Development [RECOVERY][OFFICIAL] TWRP 3.7.1-0 for Galaxy A52s 5G

[ShaDisNX255]

A question comes to my mind : Do you format data before restoring the backup (going from crDroid back to NCX) ?

Yes, I format data (because it gets encrypted if I input a password) then reboot to recovery and proceed to restore my NcX backup

 

[Arobase404]

A backup of boot, vendor_boot, dtbo, super and data should be enough to achieve what you wanted to do. Remember you must disable PIN/password in One UI when booting in TWRP in order to mount and backup your data partition correctly.

You also forget to mention the Secure folder feature which might the reason I have had so many problems with my backup and restore, including the Data partition !!! ^^

hi everyone... is it possible to flash zips (magisk or custom roms) without having an external sd card?

Reason I am asking is... after twrp installation and reboot to recovery ->

1. unable to find the magisk file via file manager or install -> went through all the folders
2. if I do data wipe, then also unable to find the file
3. if i reboot to system after data wipe, the files I had put in internal storage disappeared (phone started setting up again, and this is the culprit I guess)
4. then if i save the magisk or other files in internal storage and reboot to recovery problem is same as above steps 1,2,3

I want to completely root and install lineage os and then do other stuff. I have not done rooting since end of android 7 and once with early andriod 8. Looks like many things have changed.

Please advise and help with what I am doing wrong.

I have followed the steps given by OP and tried https://magiskzip.com/install-twrp-recovery-on-samsung-galaxy-a52s-5g/ this as well. When I try the method in this magisk link I get stuck at Flash the Disable Dm Verity Force Encrypt step because (you guessed it) can't find the file :-D.

I highly suggest you not to follow that guide since it is just a CTRL+C/CTRL+V guide for another phone where they just replaced the device name (dm-verity is not anymore a thing). Please read and follow the guide in OP and make sure not to set a lockscreen protection method to be able to decrypt your data partition.

Ok let me try this again by following OP steps. BTW just bought an external sd card

You have to connect your phone to pc with usb cable. Then, press and hold VOLUME UP + POWER KEY. When the bootloader unlocked warning appear , release the power button, keep hold Volume Up 15s

Does the patched vbmeta work for U4 bootloader?

If you’re having issues with the one in OP, you can download a newer one here.

Did a backup and now trying to restore it

OK, I restored a backup (I'm coming from official LOS and restoring NCX) and... I'm stuck in Samsung logo.
This time when restoring I had messages saying that odm, vendor could not be mounted (invalid argument).

There must be something I'm not doing right.
Now when I reboot to recovery and try to wipe cache for instance, it says my filesystem is encrypted and I may need to perform a Format Data (and loose the data I restored lol).

The thing is, I created the backup after I disabled any PIN/password or fingerprint on NCX (which is not encrypted by default by the way).

 

[Anas Abed]

Plese help I got error 255 when I restore my backup the problem only when restoring data partition any help ??

I'm answering to my own post.
When I formatted Data before restoring NCX I had to boot on LOS to have data/media created and be able to copy my backup on the phone and then restore it >> this is what activated encryption....

So I had to format data once again and boot NCX to get rid of encryption, copy again my backup and then restore.

Now all is OK.

What's TWRP?

Oh come on, you know what it is - don't try to fool me!
In case you're serious, though...

Team Win Recovery Project is a custom recovery for Android devices.
It allows you to back up and restore your data, flash custom ROMs to your device, repair broken file systems, root your device and more.

Read more about TWRP here: https://twrp.me/about/

How do I flash and set it up correctly?

Please notice that the following guide is meant for full stock devices, if you've already rooted your device you can skip it and flash directly the recovery without any extra steps.

Before starting, make sure to backup all your data and important files stored in your phone, since this procedure will format your data partition.

• Download Odin3, Samsung's Android USB Drivers, the latest TWRP's tar and a disabled vbmeta image.
• Make sure your phone's bootloader is unlocked, follow the guide below in case it isn't:

Spoiler: Unlock the bootloader

• Open the Settings app, enter Developer Options and enable OEM unlocking (If you don't see Developer Options, enter into About phone>Software info and tap "Build number" 10 times to show it).
• Enter Download Mode: to do so power off your device, connect it to a computer via an USB cable and hold both volume up and volume down buttons.
• Long press volume up to unlock the bootloader. This will wipe your data and your phone will automatically reboot.
• Go through the initial setup. Skip through all the steps since data will be wiped again later. Make sure to connect the device to Internet during the setup.
• Enter Developer Options and check that the OEM unlocking option exists and is grayed out. This means our bootloader is unlocked and your phone has no KnoxGuard lock set.

• Connect your phone to your PC and boot in Download Mode (power off your device and hold both volume up and volume down buttons).
• Open Odin3, select the TWRP tar by clicking the "AP" button and the patched vbmeta tar by clicking "USERDATA", then press the Start button.
• Reboot your phone in recovery mode: while it still plugged in your PC, hold both the power and volume up buttons.
• Once TWRP has booted you need to format again your data partition in order to be able to boot in system again. To do so touch Wipe>Format Data and follow the instructions in screen.

Bugs:

• Decryption will only work if no password/PIN/pattern is set in Android (One UI).
