I rooted this C67ML Carta+ and installed TWRP.
The TWRP recovery didn't work with touch, but I figured out how to use it by sending commands with adb. I used this method to do a full backup before trying to debloat the system. I installed a zip from github using TWRP (with adb) to remove Gapps. After this, I got a bootloop.
Okay: So I calmly went back into TWRP to restore my backup (I made two just in case). First, I wipe /data /cache and /dalvik-cache
Next, I get this:
Restore folder: '/sdcard/TWRP/BACKUPS/rk30sdk/2020-05-28--16-25-52'
Skipping MD5 check based on user setting.
Calculating restore details...
Restoring 3 partitions...
Total restore size is 499MB
Wiping System...
Formatting System using make_ext4fs...
Done.
Restoring System...
E:Unable to extract tar archive '/sdcard/TWRP/BACKUPS/rk30sdk/2020-05-28--16-25-52/system.ext4.win'
Done processing script file
Now my device is thoroughly bricked. However! I can still boot into TWRP and adb still works.
My question is this: Does anyone have a flashable zip or method that can remedy the situation? All of the links on Onyx's website are broken for this model of reader. Any help is very much appreciated.
Does anyone know how to get my backup to flash??
