Hi there,
maybe you could help me with the following problem:
what I did:
- temporarily booted TWRP.img out off bootloader
- installed TWRP.zip out off temporarily booted TWRP from external_sd
- restarted into recovery
what happens:
- TWRP is coming up
- Touchscreen not working
- when I try to temporarily boot out off bootloader again I fail with the following error message:
"Sending 'boot.img' (28464 KB) OKAY [ 0.663s]
Booting (bootloader) Failed to load/authenticate boot image: Not Found
FAILED (remote: '')
fastboot: error: Command failed"
goal:
- want to temporarily boot TWRP out off bootloader again
- get TWRP runnig with touch working
any advise?
Thx a lot!
Hi,
i'm having the exact same issue with my G7 Plus. i flashed TWRP via temporary TWRP and the permanent TWRP got stuck with no touchscreen support. Now i get the error mentioned above.
Unfortunately creating a batch loop like Vsx06 didn't work for me. I couldn't boot the TWRP image.
/2nd Edit:
Managed to boot into temp recovery with USB-C cable by making bat file with commands in loop

'fastboot reboot bootloader'
'fastboot fastboot boot twrp-3.3.1-0-lake.img'
'fastboot reboot bootloader'
'fastboot fastboot boot twrp-3.3.1-0-lake.img'
After this tried to replicate succes and it worked every time by starting 'fastboot boot xxx.img' split second before bootloader reboot was fully finished.
Is there a way to brick the bootloader, so it shows up as "Qualcomm HS-USB QDLoader 9008 (COM..)"? idk, like switching to slot b?
So i can blankflash it again? (i started with a bricked phone)

thanks in advance

I also found this thread interesting, having the same issue in another Moto Model, but since i'm not that deep into flashing, i couldn't find a way to adapt it for my G7 Plus

I found out, how to recover the phone. You have to flash a stock software command by command. Just like mentioned in the link above (for the Moto X4), i typed in every command of the flashfile.bat, which can be found in the stock software file:

You'll have something like:
fastboot getvar max-sparse-size
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot flash bluetooth BTFM.bin
fastboot flash dsp dspso.bin
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system_b system_b.img_sparsechunk.0
fastboot flash system_b system_b.img_sparsechunk.1
fastboot flash vendor vendor.img_sparsechunk.0
fastboot flash vendor vendor.img_sparsechunk.1
fastboot flash oem oem.img
fastboot flash oem_b oem_other.img
fastboot erase modemst1
fastboot erase modemst2
fastboot erase carrier
fastboot erase userdata
fastboot erase ddr
fastboot flash fsg fsg.mbn
fastboot flash bluetooth BTFM.bin
fastboot oem fb_mode_clear
fastboot reboot
After you've done this, the phone is back to stock and you can try flashing TWRP again.
This time it worked perfectly with no issues.
