AIS Playbox v2 sn:1806 Amlogic S912 - 2GB RAM - 16GB - DV8429 - Bricked

[digitalbilly]

Hi guys/gals,

I have bricked my box and I need help to recover

I have made a backup with TWRP of the Original ROM - I have checked all options except for cache.

I had Poison Rom 4.3 running on it and I thought It was running slow so I wanted to go back to the original ROM that I have made a backup of with TWRP on a USB.

I am not sure what went wrong but I can no longer get back in to recovery using the reset button and launch TWRP to restore.

only get a black screen on the TV tried different monitors as well thinking it had something to do with resolution.

I cannot boot to recovery using TWRP using USB or SD card Slot

but I do have connectivity with Usb Burnning Tool

any idea how to flash from my TWRP backup is it even possible to recover with USB Burning Tool?

I have also tried loading other firmware with s912 2/16 rom and have tried T95Z Plus rom no go
getting error: [0x10103005]Romcode/Initialize DDR/Download buffer/Read item data failed

Could try the Amlogic short pin method. Don't know if it will work with the AIS Playbox, but from the looks of it you got nothing to lose.
I did use in the past short pin root method for the fire stick 4k, worked like a charm.
I also have the playbox V2 sn:1804. So far I use it as intended for TV, without root or anything else.
Maybe in the future will try something.
If you do try the short pin method, let us know how it works?
