What am I doing incredibly stupid. I can't flash a custom ROM to this to save my life.
I have a Tab A8 SM-X200 A 12. I Downloaded the latest firmware with Frija.
Rooted it with a Magisk patched boot.img. Installed TWRP through Odin. I could
boot either into TWRP or the rooted, but otherwise stock firmware. Before flashing
a ROM, I would format the data folder to ext4, wipe everything, enter fastboot mode from TWRP and do the
fastboot flash command with no errors. See screenshot. Fastboot reboot would take me back to TWRP.
When I did TWRP > Reboot > System, the device returned to TWRP. When I did TWRP > Power Off,
The unit would hang on "The tablet is not running Samsung's official software" nag screen, and not turn off.
I have tried 2 different ROMs, lineage-19.1-20220814-UNOFFICIAL-arm64_bgS.img and
lineage-20.0-20221111-UNOFFICIAL-arm64_bvS.img. My stock tars for ODIN are AP_X200XXS1BVJ1, BL_X200XXS1BVJ1, and
CSC_XAR_X200XAR1BVI6. Could it be that the CSC_ file is BV16, and AP_ and BL_ are BVJ1 are a problem?
Using TWRP_3.7.0_12-0_X200XXS1BVJ1.tar.md5, Magisk-v25.2, and Platform Tools 33.0.3.
Treble Info: no seamless upgrades, system-arm64-ab.img.xz, Treble and VNDK, System as root A/B, Dynamic partitions.
For laughs and giggles I tried flashing the img files from TWRP and it went into a bootloop.
Remember the good old days of zip files? I don't need encryption for this tablet. It's a Lazy Boy companion.
