Tanix TX2 stuck on bootlogo? Anybody help?

[Teusjuh]

Hi everyone i have upgraded the firmware to 7.1 rom but the tx2 won’t boot.
It hangs on tx2 logo
So i have downgraded to the marshmellow firmwares but the same problem.... it won’t boot and hangs on the android logo

does anybody have a idea for an solution ?
Or is the bootrom upgrade from the 7.1 nougat the problem?

Hi ,

if a full wipe over Recovery not helps , you have to install the Stockrom new ,

after that you can try a CustomRom if available ???
