Error while backing up system apps & Softbrick

[KrischnaGabriel]

I ran into two problems: The first one is the softbrick where you might can held and the second one; repetitive errors while backing up system apps.

Softbrick; manual restoration of system apps ?

I screwed up and accidentally uninstalled system apps that were required for the phone to boot. fastboot and twrp-recovery still work tho. just didn't took a full system backup beforehand cuz for playing around with apps i have your software to restore them. Question is, where does OAndBackupX stores the backed up apps&files (they're not in the internal memory /sdcard/ ) and how can i manually restore system apps when i cant boot into the OS?

i did found the currently installed apps in /data/data, /data/app and /system/app but dont know where the backups are stored for a manual installation. I could also flash the stock rom, again, but cuz i cant find the backed up apps (and their data) all of my data would be lost as well.

-----------------------------

Description I took a backup of all apps (including system apps) and then oandbackupx gave out errors (java.io.IOException).

Steps To Reproduce

1. root a Xiaomi Redmi Note 9 Pro (the Guide i used: https://www.getdroidtips.com/twrp-recovery-redmi-note-9-pro/#Download-TWRP-Recovery) note: to root it i went into twrp-recovery > Advanced > Install Root which will root it with supersu
2. after rooting, install OAndBackupX from F-droid (https://f-droid.org/en/packages/com.machiav3lli.backup/)
3. try to backup all apps
4. while backing up, java.io.IOException errors occur

Expected behavior No error messages. A successful backup of all apps.

System Information:

• Device: Xiaomi Redmi Note 9 Pro
• Android Version: 10.0
• ROM: latest stock rom; joyeuse_eea_global_images_V12.0.1.0.QJZEUXM_20201110.0000.00_10.0_eea (https://xiaomifirmwareupdater.com/miui/joyeuse/)
• App's Version: latest; 5.0.0

Screenshots & logs Note: i took, both multiple logs(over the adb interface) and screenshots directly while and afterwards it happened.

All those errors with ...closed at 'X' before the 'Y' bytes... mean that the app is still running in the background. You can try to turn on the Stop-Cont option in advanced settings. If it still doesn't work, this means that such apps have priviliges to run non-stop. I see GSF under your failed backups, that's one of them.

Otherwise, the probablty that the restore of system apps on different setups could cause a system break is high.

Miui is causing a lot of problems for backup/restore processes, which is why you have to turn Miui optimizations off.

Where you find the backups, is where you've chosen your backup folder to be.
