[General Questions and Answers] ChristianMorris:
I'm sorry to hear that your Samsung Galaxy A22 is stuck in a boot loop. Boot loops can be frustrating, but there are a few steps you can try to try to fix the problem.

Are other Samsung users having the same issue? It's possible that other Samsung users are experiencing similar issues with their devices after the Android 13 update. It's always a good idea to check for any known issues or bugs with a new update before installing it.

Is there a way to get out of the boot loop without a factory reset? One option you can try is to boot the device into Safe Mode, which will disable all third-party apps and allow you to determine if a third-party app is causing the boot loop. To boot into Safe Mode, follow these steps:

Turn off the device.

Press and hold the Power key past the model name screen.

When "SAMSUNG" appears on the screen, release the Power key.

Immediately after releasing the Power key, press and hold the Volume down key until the device finishes restarting.

Safe mode will display in the bottom left corner of the screen.

If the device is able to boot into Safe Mode without encountering a boot loop, it's likely that a third-party app is causing the problem. In this case, you can try uninstalling any recently downloaded apps to see if that fixes the issue.

How do ADB and Fastboot work and how would they help me recover my data? ADB (Android Debug Bridge) and Fastboot are tools that allow you to communicate with your Android device from a computer. ADB can be used to run commands on the device, install apps, and perform other tasks. Fastboot allows you to flash factory images, boot images, and other files to your device.

If your device is stuck in a boot loop and you can't access the Android operating system, you may be able to use ADB and Fastboot to fix the problem. For example, you might be able to use ADB to sideload a new version of the Android operating system, or use Fastboot to flash a factory image to your device.

Can I unlock the bootloader while stuck in a boot loop? Unfortunately, it's not possible to unlock the bootloader of your device while it's stuck in a boot loop. The bootloader must be unlocked while the device is powered on and fully operational.

In summary, there are a few steps you can try to try to fix the boot loop issue on your Samsung Galaxy A22, such as booting into Safe Mode or using ADB and Fastboot to sideload a new version of the Android operating system. However, if these steps don't work, you may need to perform a factory reset to fix the problem. Be aware that a factory reset will erase all data from your device, so it's important to make a backup of your important data before proceeding.
[General Questions and Answers] ChristianMorris:
Here are a few more steps you can try if your Samsung Galaxy A22 is stuck in a boot loop:

Clear the cache partition: The cache partition stores temporary files and data, and sometimes these files can become corrupt and cause issues with the device. To clear the cache partition, follow these steps:

Turn off the device.

Press and hold the Volume up key and the Bixby key, then press and hold the Power key.

When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).

Press the Volume down key several times to highlight "wipe cache partition."

Press Power key to select.

Press the Volume down key to highlight "yes" and press the Power key to select.

When the wipe cache partition is complete, "Reboot system now" is highlighted.

Press the Power key to restart the device.

Attempt to boot the device into Download Mode: Download Mode allows you to flash firmware and other files to your device using a tool like Odin. To boot into Download Mode, follow these steps:

Turn off the device.

Press and hold the Volume down key and the Bixby key, then press and hold the Power key.

When the green Android logo displays, release all keys.

An warning screen will display. Press the Volume up key to continue.

The device will now be in Download Mode.

From Download Mode, you may be able to use a tool like Odin to flash a factory image or other firmware to your device in an attempt to fix the boot loop issue.

Try using a different charger or charging cable: In some cases, a faulty charger or charging cable can cause issues with the device, including boot loops. If you have access to another charger or charging cable, try using it to see if that helps fix the problem.

Contact Samsung support: If you've tried all of the above steps and are still unable to fix the boot loop issue, you may need to contact Samsung support for further assistance. They may be able to provide additional troubleshooting steps or repair options.

I hope these additional steps are helpful!
[General Questions and Answers] ChristianMorris:
Also, here are a few more things you can try if your Samsung Galaxy A22 is stuck in a boot loop:

Check for any updates: It's possible that a software update may be available that can fix the boot loop issue on your device. To check for updates, follow these steps:

From the Home screen, tap the Apps icon.

Tap Settings.

Scroll to and tap Software update.

Tap Download and install.

If an update is available, follow the on-screen prompts to download and install the update.

Keep in mind that installing a software update may require a stable internet connection and enough storage space on your device.

Perform a hard reset: A hard reset, also known as a factory reset, will erase all data and restore the device to its original factory settings. This can be a useful option if the boot loop issue is caused by a software problem that can't be resolved through other means. To perform a hard reset, follow these steps:

Turn off the device.

Press and hold the Volume up key and the Bixby key, then press and hold the Power key.

When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).

Press the Volume down key several times to highlight "wipe data/factory reset."

Press Power key to select.

Press the Volume down key to highlight "Yes -- delete all user data."

Press Power key to select and start the master reset.

When the master reset is complete, "Reboot system now" is highlighted.

Press the Power key to restart the device.

Keep in mind that a hard reset will erase all data from your device, so it's important to make a backup of your important data before proceeding.

Check for any physical damage: In some cases, physical damage to the device can cause it to become stuck in a boot loop. If you suspect that your device has suffered physical damage, it's a good idea to have it inspected by a professional.

Consider seeking professional repair: If you've tried all of the above steps and are still unable to fix the boot loop issue, you may need to seek professional repair services. A trained technician may be able to diagnose and fix the problem with your device.

With regards to this thread's title

Recover data with TWRP after device is stuck on boot loop?​

take note that you can recover user-data when phone gets booted into recovery mode ( Stock Recovery is good , TWRP isn't needed ) because in this mode you via ADB can pull the data you are interested in.
[General Questions and Answers] alecxs:
yeah welcome to bull****-bingo :)

(besides its fully restricted no adb) stock recovery doesn't have any access to /data at all. TWRP recovery does not support Samsung Encryption, no way to decrypt /data.

unlocking bootloader is no option as encryption keys are tied to the bootloader status and boot/recovery image signatures.

There is no way to access your data other than fix boot-loop and unlock screen.

install Odin3, download stock ROM at current bootloader level same as device (you can find on download mode screen) and flash HOME_CSC (instead CSC) to keep userdata partition.

if no HOME_CSC file exist, unpack files and flash partitions manually from mtkclient (do a backup before)
[General Questions and Answers] xXx yYy:
@Alecxs

it's not me who is the idiot here ... Take note that ADB is supported in Stock Recovery mode. :D

@nanawa

To boot into Stock Recovery mode ( Stock Recovery mode refers to Android's bootable partition in which the recovery console is installed ) on a Galaxy A22 5G is to use the physical buttons of the phone:

This is fairly straightforward. One needs to turn off the phone, press the required buttons and the phone will go straight to Stock Recovery mode.

Before one can run ADB commands in Stock Recovery mode ( one needs to have the proper ADB and USB drivers for the Galaxy A22 5G, as provided by Samsung, installed on PC ) one of course must have phone initially unplugged before entering Stock Recovery mode. When phone is started in Stock Recovery mode one has to connect phone with PC via USB-cable and start USB-Debug mode - AKA ADB.

In USB-Debug mode you even can start an Android shell and remove any encryption as shown next

mkdir C:\DCIM 2>nul
adb devices
adb shell "su && echo '--set_encrypted_filesystem=off' > /cache/recovery/command"
adb pull /sdcard/DCIM C:\DCIM
dir C:\DCIM | more
[General Questions and Answers] alecxs:
you don't have any android device running android 5+ otherwise you would know that in stock recovery adb is limited to one single cmd that is called sideload

what you can do with adb in stock recovery is NOTHING

also your "remove" of encryption is bull****. data cannot decrypted without credentials not even with root lol.

what you're referring to is cmd (on /cache partition) to disable encrypted fs (requires formatting), used only for OTA update zip unrelated to adb (and unrelated to decryption)

maybe it works on your ancient android emulator but that's different from android smartphones. do not provide "solutions" you haven't tested yourself.
[General Questions and Answers] xXx yYy:
To keep you updated:

When running recovery image from debuggable builds (i.e. -eng or -userdebug build variants, or ro.debuggable=1 in /prop.default), adbd service is enabled and started by default, which allows ADB communication. A device should be listed under adb devices

adb devices

List of devices attached

1234567890abcdef recovery

Although /system/bin/adbd is built from the same code base as the one in the normal boot, may be for most only a subset of ADB commands are meaningful under recovery, such as adb root, adb shell, adb push, adb pull etc. Since Android Q, adb shell no longer requires manually mounting /system from recovery menu.
[General Questions and Answers] alecxs:
which device you have tested was able to run adb root, adb shell, adb push, adb pull in stock recovery?

which device is released as eng or -userdebug build? name a single one

🤦

bonus: which stock recovery is able to mount encrypted /data (and how the lock screen pattern is requested without touch screen)?
[General Questions and Answers] alecxs:
of course, you have no proof and no arguments, as always...

[General Questions and Answers] nanawa:
Thank you a whole lot for taking the time to write all this, means a lot to me Christian!

But.. I can't manage to get into Safe Mode. I believe it's because it isn't a third-party app triggering the boot loop (since it all started with the update and solely because of it) but I might be wrong, as I'm not quite familiar with how that works.

As for the cache partition... I tried, but it didn't change anything :(

"Keep in mind that a hard reset will erase all data from your device, so it's important to make a backup of your important data before proceeding." Does this mean I can still make that backup, even if my phone's on bootloop?

Also.. you advised to use ADB, but can I do that if the bootloader wasn't unlocked in the first place?

Again, thank you so much for replying, truly!! <3
[General Questions and Answers] nanawa:
Thank you for correcting it!

As for "stock recovery", would you please elaborate? that's the first I'm hearing of it!
[General Questions and Answers] nanawa:
Oh my, I think I'm understanding less and less..

Does this mean ADB can't help?

Regarding the "current bootloader level same as device" I can find on the download mode screen.. I don't get what I'm supposed to look for, I attached a pic of the screen I get, if you may be so kind to tell me what to do! :)
[General Questions and Answers] nanawa:
Okok, now I get what stock recovery mode is.. I thought it was a new thing :')

So, once in stock recovery, do I just run ADB and copy paste the code you wrote?
[General Questions and Answers] nanawa:
As for the rest of the discussion I can't understand a single thing, can I or can I not retrieve data with ADB? @aIecxs @xXx yYy

Also this might be dumb to say but regarding "and how the lock screen pattern is requested without touch screen)?" my phone's also locked by finger pattern! if that makes sense 😭​

(also idk why I'm writing in bold I'm so new to this.. but please don't fight folks, I appreciate the help you're both giving me!)​
[General Questions and Answers] alecxs:
no worry, you're not the only one who doesn't understand much...

on PC download platform-tools then connect device in recovery mode and install usb drivers. now add platform-tools directory to path (or navigate to directory with 'cd') in cmd.exe

if adb is available you should see device serialno when typing 'adb devices'. that's all, the rest won't work (but please try anyway, just to proof him wrong xD)

RP SWREV: B3 means bootloader level = 3

bootloader is downgrade protected, so even in case you manage to flash ROM with lower bootloader level (for example with mtkclient) device won't boot.

you can only flash ROM with same or higher bootloader level because of downgrade protection.

kindly upload picture of recovery mode screen too, so we can check for official ROM that matches best.
[General Questions and Answers] xXx yYy:
Because you tagged me:

1. When device got booted into Recovery mode, a stripped down version of Android is loaded

what allows to perform basic tasks - this is comparable with WinRE what is based on Windows PC's recovery environment that exists by default on all Windows PCs .

2. When booting Android device into Recovery mode device's /data partition doesn't get mounted, thus no locks are got activated.

3. According to source-code of file recovery.cpp what is part of AOSP v13

any encryption can get disabled, thus all user-data beome fully readable: as I've shown some posts above this can be achieved running an ADB command whilst in Recovery mode.

DO NOT TAG ME ANYMORE BECAUSE I NO LONGER PARTICIPATE THIS THREAD.
[General Questions and Answers] alecxs:
despites that's all hypothetical (you never tested you just defend your fantasy) that requires root permissions to write on /cache (we don't have) furthermore 'disabled' is nothing else than 'destroyed' in that context and requires formatting. in no way the data can be decrypted/accessed like that (as already stated)

again, in stock recovery no adb commands work.
[General Questions and Answers] nanawa:
Yes, excuse my late reply!

I'm currently downloading it, I'll tell you if it's available!

How do I add platform-tools directory to path? (edit 2: dw I googled)

(I wish he'd be right tho, as it would be amazing if he were xD)

I'm attaching the recovery mode screen as asked, thank you so so much for the help alecxs! <3

(had to edit 1 because of the breaking the matrix error lmaoo)
[General Questions and Answers] alecxs:
so what you need is ROM with bootloader level 3 - yes that matches current build no (A225FXXU3CVK3) i will search for...

unfortunately thats already the Android 13 version

(you're not the only one btw)

https://xdaforums.com/t/4535591
[General Questions and Answers] nanawa:
Thank you a lot, I got it! But..

I had to write "adb devices" in cmd.exe, right? cause uhm.. is this it?

"C:\Users\Yoshikage Chiko>adb devices

List of devices attached

"

it's empty? :(
[General Questions and Answers] alecxs:
adbd is not running in (stock) recovery mode. select the "Apply update from ADB" entry from menu, that will enable adb sideload. you should see new device in windows device manager, there you can install android_winusb.inf Android ADB Interface driver manually (Update Driver -> Browse my computer -> Let me pick -> Show all devices -> Have Disk -> android_winusb.inf)

these are ROMs with same bootloader level

although the good thing these ROMs are flashable from Odin3, still the encryption keys are downgrade protected and I don't know if one of the parameters did increase. and, we don't know encryption keys were already upgraded or not. so it's basically trial and error.

you can decide what ROM you think was previously running before the update... download ROM from Samloader, unpack and look into files if HOME_CSC exist (required for flashing without deleting userdata)

other methods to preserve current (encrypted) userdata partition available
[General Questions and Answers] nanawa:
"apply update from usb" menu -> is that supposed to be on the recovery screen? Because my only two options are ADB and SD card (I have one, if needed!)

I'm trying to install the driver manually now :)

My region code, as in where I'm from? Italy! If I understood the question (oh and good evening fellow european!)

you can decide what ROM you think was previously running before the update... -> oh my, based on what can I decide? I don't get it.. :((

"other methods to preserve current (encrypted) userdata partition available" -> does this mean there are other methods to preserve my data?
[General Questions and Answers] alecxs:
no, not really. just other methods/tools (like mtkclient) to flash ROMs without flashing (empty) userdata. so your region code is ITV... hm, on download mode screen it's EUX

the problem is with encryption keys are bonded to various parameters (even boot/recovery image signatures) we have to figure out which is the current bonding...

you can decide on guesswork... maybe date when ROM was released?
[General Questions and Answers] nanawa:
Oh.. I see :( as for the region code, I'm not sure why it says albania, I got it from a nearby bennet store? (just found the receipt!)

By googling, I found that EUX stood for European Union, but that's not specific at all :( I really don't know the date when ROM was released.. I'm not even sure I know exactly what ROM is 😅 I'm learning so many new things these days ahah, please be patient with me😅

edit: as for the bonding, any idea on how we can figure it out boss?
[General Questions and Answers] alecxs:
I checked from samloader. EUX not available. have updated above list with ITV. there is no good way to determine what ROM/firmware is the right one, it's trial and error.

days? weeks? months? more info would be helpful.

maybe scroll through the "View recovery logs" option in recovery mode (can be huge)
[General Questions and Answers] nanawa:
a month, defintely! I remember 27th of november specifically, but by googling it says december 6th. well, that's around that time. and I decided to do it on 01/01 lol.

as for the trial and error, I'm up for it! it's ok if I make mistakes right? I hope I don't soft brick or something lol

quick question tho, you've included Android 12 and 11 in the list too. doesn't downgrading require resetting? I've heard so. I'm not sure if I have an Android 13 or 12 now, since 13 didn't boot once after downloading the update(I believe?)

Should I start with the Android 13 code?

P.S.

[General Questions and Answers] nanawa:
Regarding the recovery logs.. maybe wiping cache partition wasn't the wisest idea lol.

(if I'm correct about that being why all of the list starts with cache?)
[General Questions and Answers] alecxs:
yes, thats the location. have a look into last_log.9 (you can view contents just for fun, no need to post screenshots)

that are some more parameters (like bootloader level) but - to which encryption is tied... the downgrade protection of encryption keys is one possible reason why phone bootloops - and the reason for downgrading require resetting -.-

Android 13

A225FXXU3CVK3 2022-11-14 20221114195721

that is the update caused the issue. it probably won't work because boot/recovery signature has changed. well, I don't know what changes happen between Android 12 -> 13 but I guess Samsung forgot to tell you it requires factory reset. (seriously I have no clue how that works under the hood, maybe they are smart enough to prevent data loss... in theory)

Android 12

A225FXXU3BVI9 2022-09-24 20220924210000

that is the previous one before update. assuming that's the right build, it will work in case encryption keys are not upgraded, yet. I would try this first, it may able to fix bootloop and decrypt userdata. However, do not flash from Odin (for now) as that may factory reset. only download and have a look inside...
[General Questions and Answers] nanawa:
I wish I could understand a thing tho, looks all cool but still xD

I'll try downloading the Android 12 one! But if I can't flash from Odin, how can I have a look? :unsure:

edit: I was looking at the firmwares in here https://samfw.com/firmware/SM-A225F/ITV to download the Android 12 one but, isn't the version I have (seen on the stock recovery mode screen) A225FXXU3CVK3? (the one for Android 13)? does it not matter? :oops:
[General Questions and Answers] alecxs:
as I said, I would try the previous android version first, that one your userdata were encrypted with till 2022/12/31.

you can open files with 7-zip. there should be 5x files

AP_A225F*.tar.md5

BL_A225F*.tar.md5

CP_A225F*.tar.md5

CSC_OXM_A225F*.tar.md5

HOME_CSC_OXM_A225F*.tar.md5

for Odin, only 4x files used

from what I have read (never did and cannot confirm):

flashing HOME_CSC (instead CSC) will keep userdata. this is because HOME_CSC does not contain A22_EUR_OPEN.pit file used for re-partitioning... however, AP file still contains userdata.img (what seems quite risky to me)

search for flashing with Odin without wiping userdata. there are some rules to respect (such as uncheck checkbox for re-partitioning)

my idea would be to remove userdata.img from AP file, but the new file will be without md5 checksum (could be flashed anyway with modded Odin).

but as mentioned, we have other tools such as heimdall, mtkclient for linux with more control over partitions to be flashed. also mtkclient is capable of backup partitions.
[General Questions and Answers] nanawa:
super thankful for all this<3 I think it will take a while for the firmware to download (doing the Android 12 now :D)

as soon as it does, I'll try to apply what you said!

about the tools tho.. I'm not familiar with any of them (might have heard mtkclient before, maybe you mentioned it before?) should I try with odin then, or google more about those two? I think odin would be safer but then again, how would I know😅
[General Questions and Answers] alecxs:
do some more research about Odin without data loss. I don't know trustful source for this HOME_CSC info.

to me, backup with mtkclient would be safer (because I have linux)

(y):cool:
[General Questions and Answers] nanawa:
I don't have linux, should I download it? I only know it exists and that computer-knowledgeable ppl use it😅

Will do research, thank you! I've heard about the HOME_CSC thing as well, hopefully we can prove it right😼
