Development [RECOVERY][UNOFFICIAL] TWRP for Galaxy A22 SM-a225F/a225M Android 11+12

[physwizz]

Installing Custom Recoveries

A. Preparation.

1. Download firmware for your device
2. Extract ap file using Zarchiver and extract recovery.img from recovery.img.lz4 and compress it to recovery.tar

3. Patch the ap file with a magisk which will patch both boot.img and vbmeta.img (from magisk, choose install then select file to patch)

Exynos 850 Resources

t.me

Alternatively you can extract boot.img.lz4 and vbmeta.img.lz4 from the ap file and compress them into a new tar file and then patch that file.

note: if you don't want root then just extract the vbmeta.img and use zarchiver to add it to my twrp.tar file.
You can flash this new file from odin at step 5

For Exynos 850 android 11 use a21s patched magisk.

For Exynos 850 android 12 and most other devices use delta magisk

4. Unlock OEM in developer options
5. Attach phone to pc and reboot to download mode
6. flash patched ap file.

Extract boot.img and vbmeta.img and add them to the TWRP zip.

C. Recovery Problems

Most recovery issues can be solved by attending to the following issues.

1. Did you root using the full ap file patched Magisk .
(This contains the patched boot.img and vbmeta.img)
Exynos 850 users must use the special a217 magisk?

2. Did you then go all the way through the setup process?

3. Did you download the recovery to match your baseband?
See https://t.me/a127f_res/54 for Exynos 850 recoveries

4. Did you hold down power and volume up after Odin says pass?

5. Did you format data from stock recovery?
If you forgot to do this, just install stock recovery.img from TWRP and reboot.

6. Did you type multidisabler twice?
If it doesn't work try this

Physwizz Collection

Decrypt. If multidisabler doesn't work try this method. 1. Copy /vendor/etc/fstab.**** over to another folder. 2. Edit it to remove the line containing the word "encryption" 3. Boot into twrp 4. Use twrp file manager to replace the fstab file with the edited one. 5. Format data (not just...

t.me

7. Did you reboot to recovery by choosing reboot from the menu and then choosing recovery?

8. To avoid touch issues go to settings and untick "allow time out"

9.For touch issues use a usb mouse

physwizz(Really Old Dev) in physwizz testing & discussion

If touch doesn't work on twrp, connect a usb mouse Everyone has an old mouse at home and the adapter costs less than a cup of coffee

t.me

D.To restore Stock Recovery

1. Attach phone to pc and reboot to download mode
2. flash patched ap file or stock recovery.tar
3. reboot

Or just flash stock recovery.img from twrp and reboot.

Now, how do I flash the TWRP? The TWRP is a .zip instead of a .tar

I'm quite new to flashing recoveries, and in general, flashing GSIs and Custom Roms I want to put AOSP android 12 on my a225f, I got U 5.1 Android 13.

Unzip to find the tar

Thanks, I'll try to flash the gsi now.

hello good evening, is there a twrp compatible with android 13 one ui 5.1 binary 5? since even if I install by odin the download mode throws me the error, but I don't remember well, it says something about by lock: boot for example or what throws an error when flashing says it in that mode, and I don't know what to do anymore, I even tried patch the ap of my stock rom in magisk and flash it by odin and the same thing reaches a file and throws the error, some way to install it or another way to install a gsi.
From already thank you very much

You need to unlock bootloader.



To Unlock Bootloader
1. On phone developer options in settings allow OEM unlocking and enable usb debugging by moving both
sliders RIGHT

If you don't see the OEM unlock
-Disable Auto System Update
-Then disable Automatic date and time (Found in General Management) > then set the time back 14 days
- Connect to the internet
-Go to software update then check for update and wait a long time till it registers the device on server
-Once it's registered the OEM Unlock should be visible in the Developer Options

then connect phone to PC or to another phone
2. Reboot into download mode by holding down both Vol up and Vol down
(You might need to long press vol up to unlock bootloader)

then press vol up to continue

I already have the bootloader unlocked and in OEM activated and with A13 one ui 5.1 binary 5 the most recent is, what I don't think I have activated is usb debugging but the rest did and it gave me errors in anything I flashed

In the end you were right, I had it blocked to the bootloader, I already installed recovery and others but I want to install gsi and I can't find the system partition to choose to install it there, I get a lot of partitions but I don't know which one to choose, these are:
vendor, product, odm, prism, optics, mnt/vendor/efs, misc, recovery, boot, vbmeta_vendor, vbmeta_system, seccfg, tee1, tzar, scp1, sspm_1, md1img, gz1, dtbo, vbmeta, uh, bootloader, md_udc, efs, omr, optics image, param, prism image, reserved, sec1, steady, super, up_param, super (system vendor product odm)

I think you forgot to do 1 step, did you write multidisabler in terminal? I also forgot to do it and it bootlooped for me too.

 

[davidvaner]

I think you forgot to do 1 step, did you write multidisabler in terminal? I also forgot to do it and it bootlooped for me too.

All the steps were done, as I am indicating, the issue is that as I indicated again, I get a warning in red letters that I am using unofficial software and the phone restarts.
