2) Once S-OFF, can I change M8t into either US or Taiwan stock version so that the phone can receive other country's OTA in the future? Only changing CID and installing different country RUU are required to achieve this ?
3) M8t supports WCDMA/TD-SCDMA and TDD/FDD-LTE. After S-OFF, flashing other country's stock Sense ROM, will the radio be affected, rendering it useless or limited connection? (Not sure the stock ROM, firewarre, radio and recovery in ZIP file are compatible to China Mobile)?
