mine was already bricked and no sign of life except when the light opens when charged thats all and when connected to the computer it just show APX but after few days later it opened and worked like it wasnt bricked i dunno what happened but the only thing i remembered is i prayed so hard to help me fix it xD
Indeed, 100% accurate!
Once the killer roms upgrade has been applied, the tablet is dead period. Unless an nvflash package surface this recall is indeed a waste of hardware! Nvflash is fairly common with older nvidia chipset but it's been less and less common with the recent SOC they released. The best is to remove the OTA before your tablet get killed.
The only question I still have about the recall process is the fact that the made us enter a code inside the recalled tablet, I suspect we unlocked something inside the recalled tablet so that the kill switch can kill the recalled tablet, I would not be surprised that the kill switch would not work on a regular tablet as you would need to enter the code to allow the kill to happen, however I am not yet ready to do a proof of concept test on this theory yet on my hardware
I would find strange that any tablet can be killed by urgent OTA, to me that would be opening a HUGE security hole ..
