Hi, I am a new user but I have been reading xda for many years.
Today I had a big problem later I have followed the guide (i presume correctly but I am not sure): https://forum.xda-developers.com/ga...pment/guide-multi-boot-note-pro-12-2-t3575495
- TWRP 3.1.1
- Resurrection Remix 5.8.5 as main OS (fresh install today but installed with TWRP 3.0.2) and working
- DualBootPatcherAndroid-9.3.0.r463.g1fc7bbd0-snapshot installed
- Set kernel done
- Set UI mode (clicked by mistake but I did not know how to turn it off after)
- Lineage 15.1 zip patched (slot lineage151) and saved to internal rom
- Boot to TWRP and lineage.zip install.
Here i have done a mistake, installed then also gapps stock 7.1 patched for same slot, (I have confused 15.1 with 14.1). Errors on gapps install that I have ignored.
- Reboot
Note12 not boot and stucks on Samsung logo for a some time and then it has appeared "android download do not turn off target" (Odin Mode).
I have waited some minutes and the I have forced power off.
Now Note12 not turn on anymore, even the charging logo not appears if i connect charger to recharge battery (but there is a 0.3Amps current consumption).
Battery was over 60-70% when I flashed 15.1
If I connect Note12 to PC Windows detects a Samsung Mobile USB CDC composite device but nothing happens.
Suggestions for solving or I have to throw my Note12 to trash can ?
PS
I have tried many keys combinations
Power button
Volume Up + Home button + Power button
Volume Down + Home button + Power button
Volume Down + Power button
Volume Up + Power button
but nothing happens and no screen output
EDIT:
Found a guide that tell to hold Power Button for 30 sec.
I has worked, Note12 power on but goes to Odin Mode
I suppose that now I have to reflash from zero with Samsung Fw or there is a way to recover actual installation (with TWRP) ?
EDIT2:
Resolved!
Power + Volume Up hold for 30 sec will boot to TWRP 3.1.1
I reinstall the Fw without ODIN
