HTC One M8 Unbrand - Help topic

Hi folks,

I have just bought a new UK HTC One M8 on Vodafone after having problems with my Canadian HTC One which didn't have the compatible LTE frequency for UK.

Anyhow.. I understand to debrand I need to S-OFF first, change CID to HTC__001 and then flash a stock firmware.

Just need some help with the following:

• Do I need to do something to the MID? (if so, what should it be for stock UK unlocked/unbranded version?)


• Can the debrand be done without rooting the device (if no, is it a temp root? so I can use the bank apps etc)


• Does the firewater method permanently root the phone?


• What's the best firmware to flash so I can get the future OTA?

Thanks in advance.

Regards
