[Please help] Dead Teclast p20hd after flashing
(16-12-2021, 03:45 PM)teclastp2020hd Hello!
After flashing my device with a new boot img (magisk patched) using SPD Research Tool it doesn't turn on any more (black screen/no usb connection). but the SPD Research tool showed successful flash.
I've tried reconnecting the battery. I've been reading https://www.hovatek.com/forum/thread-808.html
To check possible usb connection I use udevadm monitor on linux (tested with other devices).

I think before that I tried to flash a wrong vbmeta and boot image..
So I tried to flash a new signed vbmeta img -> failed: wait input timeout (I kept holding the buttons during the whole flashing process, I'm using the latest r24 flash tool) How to fix that?

Is this the vbmeta from the pac file? Or you created and signed one?

thank you hovatek, it was signed by myself, but I decided to reflash everything. Now it evens shows the boot-logo and fastboot mode. I sucessfully unlocked the bootloader.
but I couldn't flash nv_lte and super partition. Maybe I'm using a wrong pac.
Do you know firmware files of old version for my device (teclast p20hd, n6h3)?
