Hi, I got this tablet recently and I managed to get TWRP working but by my fault made a system wipe. Problem is my device is shown as tb_8504X , this underscore is preventing me from installing update. I tried changing updater-script and rezipping but TWRP gives Invalid zip file format error. I tried several times, different zip methods, different software etc. All fail.
I got stuck here just because of a typo...
Use QFIL and flash the latest firmware, the latest one should end with 31...

I think that's a problem with the TWRP build you're using. Try to flash the ROM in a different TWRP.

You're probably still using Android N firmware. Make sure to upgrade to Oreo first.
