Im on 220.127.116.11 TWRP, is that good ? And i have same problem as thread creator - PC didn´t recognize my tablet and i have installed android skd and adb utilities.
EDIT: microSD card works, i flash rom thanks to it. But iam scared when i restart and it wont work i didnt get back into recovery.
Thank god I made it. I formated only /sdcard data so i just install ROM from that folder and everything works properly.
