Hello,

I was attempting to port TWRP for my LH8n device with the twrpdtgen tool and I accidentally flashed the generated bootimg into the boot partition. After turning the phone on, TWRP started but turns out it wasn't set up properly and it does not respond to touches. I am stuck in the home screen of TWRP with no way of accessing any options, I have tried ADB and even an OTG mouse.

The device is completely unrecognized on my computer while in TWRP and it is impossible to even shut the phone down, unless I drain out the battery. The problem is, since I cannot access the phone's recovery anymore, I cannot boot into flashboot either, and I am stuck on the TWRP screen.

I have tried various tools like, SP Flash, mtkclient and bypass utils, all of them have failed one way or the other. The bootloader is still unlocked but it fails to boot into brom.

On attempting to run bypass-utility, it detects by phone when I try to reboot, but it throws the following error on loop:

Code:

I had some hopes for mtkclient but that too failed with the following:

Is there any way for me to at least open fastboot? I'm trying to flash the stock boot.img back onto the phone.

Thank you for your help!

UPDATE: I fixed the issue by using a tool called 'Android Utility PRO'. It successfully crashed BROM and let me boot into fastboot.
