iPhone or Android Stuck in a Bootloop After an iOS or OTA Update With Unbacked-Up Photos (DFU vs. Recovery Mode, Update Without Erase, and Error 14 Full Storage)¶

Waking up after an overnight iOS or Android Over-The-Air (OTA) software update to find your phone trapped in an endless reboot cycle, flashing the Apple logo, Google G, or Samsung Galaxy splash screen every 15 to 90 seconds before blacking out, is a severe data emergency when years of unbacked-up family photos, videos, or legal records live solely on the internal NAND flash chip. Modern smartphones use hardware-enforced File-Based Encryption (FBE on Android using fscrypt and Data Protection Class keys on iOS paired with the hardware Secure Enclave / Titan M2 / Knox Vault coprocessor). No repair shop can unsolder your storage chip and read it inside an external reader without your living motherboard and unlocking passcode.

However, a post-update bootloop almost never means your encrypted user data partition (/dev/disk0s1s2 on iOS or /data on Android) has been erased. Instead, the operating system failed mid-migration because the storage volume had zero free scratch blocks to unpack the new system snapshot, causing iTunes or Finder to throw Error 14, Error 1110, Error 9, or Error 4013, or causing Android Recovery to drop into a Cannot load Android system. Your data may be corrupt prompt where clicking Restore arba Factory data reset permanently destroys the cryptographic keys protecting your photos. If your phone also has water damage or a cracked display, consult broken or water-damaged phone recovery ir iOS iPhone frozen, black screen, and recovery mode. If you face an immediate physical or medical emergency while your primary phone is bricked, borrow a nearby handset to call your local emergency number (911 JAV ir Kanadoje, 112 visoje Europos Sąjungoje, 999 Jungtinėje Karalystėje) arba patikrinkite mūsų katalogą pagalbos numeriai.

1. DO NOT click "Restore iPhone" in Finder or iTunes, and DO NOT select "Wipe data/factory reset" in Android Recovery: Clicking Restore or Factory data reset issues an immediate cryptographic key obliteration command (effaceable-storage wipe on iOS or metadata key destruction on Android) that renders every unbacked-up photo and video mathematically unrecoverable in under two seconds.
2. Disconnect the phone from power if it is hot, let it cool to room temperature (20 degrees Celsius / 68 degrees Fahrenheit), and time the bootloop cycle:
3. 5-second instant flash loop: Indicates a depleted battery unable to sustain the peak 2.5A current draw of kernel initialization, or a shorted front proximity sensor flex cable (flood illuminator on Face ID iPhones). Charge the phone on a 5V / 1A (5W) USB-A brick for 45 minutes before attempting software recovery.
4. 45-to-120-second slow loop: Indicates the bootloader (iBoot arba ABL) loads the kernel, mounts the APFS arba ext4/f2fs root volume, and crashes during user-space migration (DataMigrator choking on 0 bytes of free space). This is the Full Storage Update Bootloop (Error 14 / Error 1110), and your photos remain intact inside the encrypted user partition.
5. Never put a bootlooping iPhone into DFU Mode (Black Screen) when trying to save data; use Recovery Mode (Cable-to-Laptop Screen) instead:
6. ** Kodėl DFU Mode is a trap**: Device Firmware Upgrade (DFU) mode bypasses iBoot and drops to the raw SecureROM bootrom level. Standard Apple Finder and iTunes workflows from DFU mode force a full partition erase (Restore) and cannot execute an in-place Update (Retain User Data).
7. ** Kodėl Recovery Mode is required**: In Recovery Mode (showing a charging cable pointing toward a laptop), iBoot is active and allows an in-place Update that overwrites only the system OS partition while leaving your /private/var user photo volume untouched.
8. Use a direct USB-A to Lightning arba USB-A to USB-C data cable plugged into a rear motherboard port on a desktop PC or Mac: Do not use USB-C to Lightning fast-charge cables during firmware flashing (Error 4013 and mid-flash drops frequently occur over USB Power Delivery negotiation handshakes). Never connect through a USB hub.
9. If Finder or iTunes has already thrown Error 1110 arba Error 14, stop repeating standard iTunes "Update": When an iPhone throws Error 1110 arba Error 14, the phone has zero free blocks left to complete the APFS snapshot merge. Running standard iTunes Update repeatedly risks corrupting the APFS B-tree catalog. Switch immediately to 3uTools (Smart Flash -> Retain User's Data with the latest signed IPSW) or Apple's latest Apple Devices / macOS Finder build.
10. Check iCloud.com ir photos.google.com from a separate computer before assuming your photos are gone: Roughly 30 percent of users discover that a partial background sync occurred over Wi-Fi while the phone was sitting on the charger during the initial OTA download before the reboot began.

Phase 1: Why updates cause bootloops and why your photos are still inside¶

When you tap "Install Now" or allow an overnight automatic update on iOS or Android, the operating system does not simply copy a few files like a desktop PC. Understanding the storage architecture explains why the phone crashes and how to save it.

1. The anatomy of an iOS APFS System Snapshot and User Data split (iOS 15 per iOS 18+)¶

Modern iPhones format their internal NVMe NAND flash using Apple File System (APFS) divided into logical volumes sharing a single storage container pool: - The Sealed System Volume (/dev/disk0s1s1): Contains the core iOS operating system, cryptographically sealed with a SHA-256 Merkle tree (Signed System Volume / SSV). - The User Data Volume (/dev/disk0s1s2 mounted at /private/var): Contains your camera roll (DCIM), SQLite databases (sms.db, Photos.sqlite), WhatsApp history, and app containers, protected by hardware encryption tied to your passcode and the Secure Enclave. - ** Kodėl Error 14 ir Error 1110 happen**: Because both volumes share the same physical APFS container free-space pool, if your 128 GB or 256 GB iPhone had 127.4 GB of photos and cached apps (System Data), the OTA updater often miscalculates the free space required for step two of the reboot: running the post-upgrade database migrator (DataMigrator). Midway through upgrading your Photos.sqlite database and system keychains to the new iOS schema, the APFS allocator hits ENOSPC (No space left on device, 0 free blocks). The kernel panics, reboots, attempts to resume the migration, hits 0 free blocks again, and traps the phone in an infinite 90-second bootloop.

2. The anatomy of Android Virtual A/B Dual-Slot Updates vs. Legacy Recovery OTA atnaujinimai¶

Android phones use one of two update architectures: - Google Pixel, Motorola, OnePlus, Xiaomi (Virtual A/B Dual-Slot Updates): The phone maintains two system slot sets (Slot A ir Slot B) plus Copy-on-Write (COW) snapshots stored inside /data/gsi/ota. If the update to Slot B fails to boot 3 to 7 consecutive times, the bootloader's boot_control HAL is designed to roll back to the working Slot A. However, if /data ran out of space during the snapuserd Copy-on-Write merge after first boot, or if dm-verity detects a corrupted block, the phone freezes on the boot animation or drops to the Cannot load Android system screen. - Samsung Galaxy Models (One UI Partition Migrations): The phone reboots into the recovery kernel to patch /system, /vendor, ir /product directly, then boots into Android to run dex2oat (Optimizing apps) and database migrations. If the battery dips or storage fills up during Optimizing apps, the system crashes into a loop.

3. Recovery Mode vs. DFU Mode vs. Normal Boot¶

Phase 2: Step-by-step iPhone photo rescue (Recovery Mode, Error 14 / 1110, ir 3uTools Retain User Data)¶

If your iPhone is stuck on the Apple logo or rebooting after an iOS update, follow these steps in strict order.

Step 1: Force the iPhone out of the loop and into Recovery Mode (Not DFU)¶

1. Unplug the iPhone from the computer first, wait 5 seconds, and plug the iPhone into your Mac or Windows PC using a reliable USB-A to Lightning arba USB-A to USB-C cable.
2. Execute the button sequence for your exact iPhone model while the cable is plugged in:
3. iPhone 8 per iPhone 17 ir iPhone SE (2nd/3rd Gen): Press and quickly release Volume Up, press and quickly release Volume Down, then press and keep holding the Side (Power) button firmly. Do not let go when the Apple logo appears. Keep holding it (15 to 25 seconds) until the screen switches to the cable pointing to a laptop graphic (Recovery Mode), then release.
4. iPhone 7 ir iPhone 7 Plus: Press and hold both the Side (Power) button and the Volume Down button together until the cable-to-laptop screen appears.
5. iPhone 6s, iPhone SE (1st Gen), and older: Press and hold both the Home button and the Side/Top button together until the cable-to-laptop screen appears.
6. Check if the phone simply needed a kick out of a stuck nvram boot flag:
7. Occasionally, an iPhone finishes installing the update properly, but its auto-boot NVRAM flag stays set to false.
8. Before flashing anything, open 3uTools (Windows/Mac) or irecovery (irecovery -n). If the tool detects the phone in Recovery Mode, click Exit Recovery Mode once.
9. If the phone boots to your lock screen, unlock it and immediately turn on Airplane Mode, then delete 5 to 10 GB of large apps (Settings -> General -> iPhone Storage) before backing up your photos over USB. If it falls back into the Apple logo bootloop, proceed to Step 2.

Step 2: Choosing between Finder / Apple Devices "Update" prieš 3uTools "Retain User's Data"¶

Case A: You had plenty of free space (10 GB+ free) before the update¶

1. Open Finder (macOS Catalina 10.15+) or the official Apple Devices app / iTunes (Windows 10/11).
2. When the dialog box reads "There is a problem with the iPhone that requires it to be updated or restored," click "Update" (verify you are clicking Update and NOT Restore).
3. Wait while your computer downloads the 7 GB to 9 GB .ipsw firmware package. If the download takes longer than 15 minutes, the iPhone's iBoot watchdog timer will exit Recovery Mode and start bootlooping again. Let the download finish in the background, then repeat Step 1 to put the iPhone back into Recovery Mode and click Update again.

Case B: Your iPhone storage was nearly full, OR Finder/iTunes threw Error 14 arba Error 1110¶

If your iPhone warned "iPhone Storage Full" before the update, or if clicking Update failed halfway through the progress bar with Error (14) arba (1110):

1. Understand what Error 14 ir Error 1110 mean:
2. Error 1110: Explicitly means NAND out of space during APFS volume update / migration.
3. Error 14: Indicates a firmware truncation mid-write triggered when the ramdisk tries to expand system files onto a 99.9 percent full NAND chip.
4. Why flashing a NEWER iOS point-release .ipsw via 3uTools (Retain User's Data) succeeds where iTunes fails:
5. Standard iTunes Update sends a generic recovery command that stumbles over leftover OTA staging cache files in /private/var/MobileSoftwareUpdate.
6. Using 3uTools (Smart Flash) with Retain User's Data selected passes the -u (upgrade) parameter to idevicerestore while clearing stale temporary update caches and installing the newest signed iOS build whose updated DataMigrator binary includes Apple's compact in-place migration fix.
7. Exact 3uTools Retain User's Data Rescue Procedure (Windows / macOS):
8. Install 3uTools (3u.com) ir patikrinkite, ar įdiegtos oficialios Apple Mobile Device Support tvarkyklės.
9. Connect the iPhone in Recovery Mode (cable-to-laptop screen) using a rear motherboard USB-A port and an original USB-A to Lightning / USB-C cable.
10. Click the Smart Flash tab at the top of 3uTools and select the latest signed stable iOS version under Available Firmwares (or a newer signed RC/Beta build if available, as upward schema migrations succeed more reliably than same-version re-flashes).
11. Click Download and wait until the .ipsw file shows Downloaded / Verified 100% locally before proceeding.
12. At the bottom of the window, inspect the three radio buttons: Quick Flash Mode (Wipes data), Retain User's Data (SELECT THIS ONE), and Anti-Recovery Flash (Wipes data).
13. Double-check that the checkmark is on Retain User's Data, click Flash, and confirm in the popup that it will keep user data.
14. Do not touch the cable or phone while the progress bar passes through Extracting Firmware -> Sending RestoreRamDisk -> Updating FileSystem -> Verifying Restore (12 to 25 minutes).
15. When the phone boots to Swipe up to recover and prompts for your 6-digit Passcode, enter your passcode and let Attempting data recovery... complete.
16. CRITICAL POST-BOOT STEP: The moment you reach your Home Screen, turn on Airplane Mode so iCloud, WhatsApp, and Mail do not download new messages and fill the remaining 50 MB of storage, which would cause a second bootloop. Go to Settings -> General -> iPhone Storage, delete or offload 5 to 15 GB of large apps (Spotify, YouTube, Instagram, games) to free space in the APFS container, then copy your photos off via USB immediately.

Phase 3: Rescuing the "Fake Software Bootloop" on iPhone X through iPhone 16 (Earpiece / Proximity Sensor Flex Short & Error 4013)¶

What if your iPhone reboots every 5 to 15 seconds on the Apple logo, or fails in Finder or 3uTools at 19% (Waiting for iPhone) with Error 4013?

1. The Face ID Earpiece and Proximity Sensor Flex Short (iPhone X per iPhone 14):
2. Inside the top bezel of your iPhone screen sits a ribbon cable containing the earpiece speaker, ambient light sensor, proximity sensor, and Face ID flood illuminator.
3. Over time, moisture from rain, sweat during calls, or humid bathrooms seeps through the top acoustic mesh grille and corrodes the I2C communication line on the proximity and flood illuminator sensor.
4. During the early seconds of booting iOS, the kernel queries every peripheral on the I2C bus. When the corroded top sensor flex pulls the I2C clock or data line low, the kernel hangs, watchdogs out, and reboots the phone on the Apple logo (or throws Error 4013 during a Recovery Mode update).
5. How a 5-minute hardware disconnect saves 100% of your photos with zero soldering:
6. If your iPhone fails with Error 4013 after trying a known-good USB-A cable, or if it loops every 5 to 10 seconds before reaching the slow migration phase, take the phone to an independent repair technician and give them this instruction: > "Do NOT wipe or restore my phone. Please open the display, temporarily disconnect ONLY the top earpiece and proximity sensor flex cable from the logic board, and press the power button to test if it boots to the lock screen."
7. Unplugging that single corroded top ribbon cable allows the iPhone to boot straight to the lock screen in 20 seconds with every photo and video intact. Unlock with your 6-digit passcode and back up all your photos immediately.

Phase 4: Step-by-step Android photo rescue (Safe Mode, Samsung Odin HOME_CSC, and Google Pixel ADB Sideload)¶

Method 1: Escaping the Android "Cannot load Android system. Your data may be corrupt" Screen¶

Kai po atnaujinimo Android telefono nepavyksta paleisti 3 kartus iš eilės, įkrovos įkroviklis paleidžiamas juodame atkūrimo ekrane ir siūlo [ Try again ] ir [ Factory data reset ]. 1. NEVER select Factory data reset: Highlight Try again, press Power, and immediately press and hold Volume Down continuously as soon as the boot logo appears. 2. Holding Volume Down throughout the boot animation forces Android into Safe Mode, which disables third-party launchers, overlays, and corporate MDM profiles that often crash system_server after an OS upgrade. Once on the lock screen in Safe Mode, unlock the phone, connect it to a PC via USB (File Transfer / MTP), copy your DCIM ir Pictures folders off immediately, and free up 10 GB of storage space before rebooting normally.

Method 2: Rescuing a Samsung Galaxy Bootloop Using Odin + HOME_CSC (Retains All Photos)¶

If a Samsung Galaxy (S21 per S25, Z Fold, Z Flip, arba A-series) is stuck on the SAMSUNG logo after a One UI update: 1. First, enter Samsung Recovery Mode (connect the phone to a PC via USB cable, hold Volume Up + Side Power button) and select Wipe cache partition (making sure you DO NOT select Wipe data/factory reset above it), then select Reboot system now. Wiping /cache deletes zero personal photos and fixes roughly 25 percent of One UI update loops. 2. If wiping /cache does not stop the loop, download the official Samsung firmware package for your exact model and carrier CSC (using Frija arba Bifrost). It extracts into 5 files: BL_, AP_, CP_, CSC_ (WIPES DATA), and HOME_CSC_ (PRESERVES DATA). 3. Enter Samsung Download Mode (Odin Mode) by holding Volume Up + Volume Down while plugging in a PC USB-C cable, then press Volume Up. 4. In Odin3 (v3.14.4), load BL, AP, ir CP into their matching slots, and in the CSC slot SELECT HOME_CSC_...tar.md5 (NEVER load the regular CSC_ file). Verify Re-Partition is unchecked, and click Start. In 6 minutes, your Galaxy will boot to the lock screen with all photos intact.

Method 3: Rescuing a Google Pixel Bootloop via ADB Sideload of the Official Full OTA Image¶

Google provides full OTA Rescue Images (developers.google.com/android/ota) that fix a post-update bootloop even when the bootloader is locked (OEM Unlocking is OFF) and without wiping /data: 1. Download Android SDK Platform-Tools (adb) and the latest Full OTA .zip file for your exact Pixel model from developers.google.com/android/ota. 2. Boot the Pixel into Fastboot Mode (Power + Volume Down), select Recovery mode, and on the No command screen hold Power, press Volume Up once, and release. 3. Select Apply update from ADB, connect the Pixel to your computer via USB, verify connection with adb devices, and run:

adb sideload ota-image-filename.zip

Dažnai užduodami klausimai¶

Ar duomenų atkūrimo laboratorija gali paimti saugojimo lustą (NAND) išjungti mano įkrovos iPhone arba Android pagrindinės plokštės plokštę ir tiesiogiai skaityti nuotraukas?¶

Ne, ne jokiame „iPhone“, pagamintame nuo to laiko iPhone 5s (2013) arba bet koks modernus Android telefonas, pagamintas nuo to laiko Android 7.0 ir naujesnės versijos. Kiekvienas šiuolaikinis išmanusis telefonas naudoja privalomą aparatinės įrangos šifravimą („Apple“. Saugus anklavas UID raktas arba Android Titanas M2 / Knox Vault / TEE su aparatūra susietą raktą kartu su užrakinimo ekrano slaptažodžiu). Neapdoroti duomenys, įrašyti į NAND Flash lustas yra beprasmis kriptografinis triukšmas be unikalaus silicio lydyto procesoriaus (`SoC`) ir kriptografinį koprocesorių iš tikslios pagrindinės plokštės, paleidžiant ir atrakinant failų šifravimo raktus RAM. Net geriausios kriminalistikos laboratorijos atkuria nuotraukas iš sugedusių ar paleidžiamų telefonų pagrindinės plokštės taisymas arba įkrovos kilpos pašalinimas, kad telefonas galėtų paleisti užrakinimo ekraną ir priimti jūsų kodą.

Why did Apple tell me at the Genius Bar that the only option is to "Restore" (wipe) my iPhone when it has Error 14 or Error 1110?¶

Apple Retail Store Genius Bar technicians are bound by strict internal support protocols and diagnostic tools (`AST2` and Finder) that only provide two buttons: Atnaujinti ir Restore. In addition, Apple's standard retail repair warranty expressly disclaims responsibility for customer data backup. When a standard Finder Atnaujinti nepavyksta vieną kartą su 14 klaida arba Klaida 1110 kadangi telefono saugykla buvo pilna, parduotuvės techniko scenarijus nurodo spustelėti Restore arba pakeiskite ragelį. Jiems neleidžiama naudoti trečiųjų šalių IdeviceRestore įvyniojimai (3uTools išsaugo vartotojo duomenis), „Flash“ naujesnis leidimas - kandidatas .ipsw stato apeiti įstrigusį DataMigrator, arba atjunkite trumpąjį jungiklį I2C lankstus artumo jutiklio laidas, leidžiantis nukopijuoti nuotraukas.

Kuo skiriasi DFU režimas nuo atkūrimo režimo ir kodėl tiek daug „YouTube“ vaizdo įrašų pavojingai liepia žmonėms naudoti DFU režimą?¶

Daugybė bendrų trikčių šalinimo tinklaraščių klaidina Atkūrimo režimas (kai ekrane rodomas įkrovimo laidas, nukreiptas į nešiojamąjį kompiuterį) su DFU režimas (Įrenginio programinės įrangos atnaujinimo režimas, kai ekranas yra visiškai juodas). Kai įdedate iPhone DFU režimas ir prijunkite jį prie „Finder“ arba „iTunes“, „Apple“ programinė įranga tampa pilka arba pašalinama vietoje Atnaujinti kelią ir verčia užbaigti Atkurti iPhone (kuris visam laikui išvalo visas nuotraukas ir vartotojo duomenis). Jūs turėtumėte visada naudokite atkūrimo režimą (kabelio ir nešiojamojo kompiuterio ekranas), kai bandote išsaugoti duomenis be atsarginių kopijų, ir palieskite DFU režimą tik naudodami specializuotą įrankį, kuris aiškiai verčia Išsaugoti vartotojo duomenis žyma, kai negalima įjungti paties atkūrimo režimo.

Kai ištaisius visos saugyklos įkrovos kilpą, mano telefonas pagaliau įsijungia, kodėl pasakėte prieš kurdami atsargines nuotraukų kopijas įjungti lėktuvo režimą?¶

Kai telefonas vos išgyvena visos saugyklos įkrovos kilpos gelbėjimą (14 klaida arba Klaida 1110), jo vartotojo skaidinyje dažnai yra mažiau nei 100 megabaitų liko laisvos vietos. Iš karto, kai telefonas prisijungia prie „Wi-Fi“ arba mobiliojo ryšio duomenų pagrindiniame ekrane, foniniai demonai (WhatsApp, iMessage, paštas, Instagramas, Apple podcast'ai, ir Indeksavimas dėmesio centre) nedelsdami pradėkite siųsti į eilę esančius pranešimus ir generuoti duomenų bazės talpyklas. Per 90 sekundžių šie foniniai atsisiuntimai sunaudoja galutinį failą 100 MB laisvos vietos, sukelia Springboard to crash and throwing your phone right back into a second bootloop. Turning on Airplane Mode the second you unlock the screen stops all incoming data so you can calmly delete 5 to 10 large apps (Settings -> General -> iPhone Storage), free up 15 GB of safe disk space, and copy your camera roll to a computer over a USB cable.
