If you had trouble with the touch screen, give the new release a try. It should be fixed. Thanks to @joaoppecurto for testing.
I even tried flashing aosp official GSI, twrp fastboot working fine. A little off-topic but 5G isnt working with this GSI
Turn on Legacy mode in the V4A app. I was very lucky to find this XDA thread which helped me a lot with my Galaxy S4 (RIP, you will be missed) and my current A22 5G.
Navigate to
/data/adb/modules/ViPER4AndroidFX (in root) and open post-fs-data.sh. Enter a new line and paste:magiskpolicy --live 'allow audioserver audioserver_tmpfs file { read write execute }'
magiskpolicy --live 'allow audioserver system_file file { execmod }'
magiskpolicy --live 'allow mediaserver mediaserver_tmpfs file { read write execute }'
magiskpolicy --live 'allow mediaserver system_file file { execmod }'
magiskpolicy --live 'allow audioserver unlabeled file { read write execute open getattr }'
magiskpolicy --live 'allow hal_audio_default hal_audio_default process { execmem }'
magiskpolicy --live 'allow hal_audio_default hal_audio_default_tmpfs file { execute }'
magiskpolicy --live 'allow hal_audio_default audio_data_file dir { search }'
magiskpolicy --live 'allow app app_data_file file { execute_no_trans }'
magiskpolicy --live 'allow mtk_hal_audio mtk_hal_audio_tmpfs file { execute }'
magiskpolicy --live 'allow mtk_hal_audio sysfs_dt_firmware_android file { read }'
magiskpolicy --live 'allow mtk_hal_audio mtk_hal_audio process { execmem }'
magiskpolicy --live 'allow vendor_default_prop vendor_default_prop file { read }'
magiskpolicy --live 'allow mtk_hal_audio metadata_file dir { search }'
magiskpolicy --live 'allow mtk_hal_audio debugfs_ion dir { search }'then save the file, and reboot. Should work now.
Anyone else getting:
Not sure if it's normal or not because I also get something similar in the Magisk logs.
E: Unable to unlock /dev/block/mmcblk0p[number] for flashing: (null).Not sure if it's normal or not because I also get something similar in the Magisk logs.
I have the same problem, but no matter what I do, the phone still restarts on the Samsung logo
You had to go to fastboot via twrp, did you go there? Try to reinstall the driver, I used lib usb
Try to download this firmware and install https://sourceforge.net/projects/tr.../crdrom-v224-201019-arm64-bgN.img.xz/download

It took me sometime, but I can now share with you a TWRP with basic functionality. You of course flash at your own risk. I am not responsible for lost warranty, lost data or any other damage to your device.
This Build of TWRP is based on:
- Firmware: A226BXXU4AVB1
- TWRP-11 minimal manifest
- Device Tree
- Kernel source
Working:
- flash of zips
- fastbootd
- flashing of GSI images (via fastbootd)
- MTP
Not working:
- Probably a lot of stuff ...
What you need:
- Unlocked bootloader.
- Odin3 v3.13.1
- android platform-tools and device driver.
- adb and fastboot
- Magisk or GSI depending on what you want to do.
- Patience, the device can be very tricky to get to download mode.
How to flash:
Be advised that this build is a work in progress and is not ready as a daily driver. Only flash if you know what you are doing.
- First read all points below, without doing anything. Warning, you will lose all your data!
- Download the recovery.tar from here.
- You start off in Odin, put recovery.tar in AP slot and the vbmeta_disabled_R.tar in the USERDATA slot, uncheck auto-reboot.
- After the flash is completed hold down power + volume down, instantly after device goes Black screen press and hold power + vol up to boot to TWRP
- if you didn't get to TWRP, you have to flash again.
- In TWRP, go to Advanced → terminal.
- Type multidisabler two times.
- Now go to Wipe → Format Data (not wipe) → and type yes.
- You can boot to system now.
Hot to install Magisk:
Method 1, Micro-SDCard- Download Magisk from here, rename the file from .apk to .zip
- Save the file to a Mico-SDCard
- Reboot the phone to TWRP.
- Go to Install → Select Storage → Micro-SDCard. In the file system, choose Magisk-vXX.X.zip and swipe to confirm flash.
- You can now Reboot to System
Method 2, sideload- Download Magisk onto your PC from here, rename the file from .apk to .zip.
- Reboot the Phone into TWRP. Go to Advanced → ADB Sideload → Swipe to start Sideload.
- On your PC, type in a Terminal adb sideload Magisk-v24.3.zip
- You can now Reboot to System. adb reboot system
How to install GSI:
- Go to Wipe → Format Data (not wipe) → and type yes.
- Now reboot to fastboot.
- Connect the phone to your pc and startup a terminal of your choice.
- In the terminal type fastboot flash system name-of-your-gsi-iamge.img (it has to be a .img file, extract .img.xz files do not just rename them).
- You should now be good to go and can reboot to system.
