Flash Smart Ultra 6 to stock ROM

mrochester · 12 Dec 2015 at 13:28

Hi all

Can anyone tell me what tools I need to flash a previously rooted Smart Ultra 6 back to the stock 5.0.2 ROM? I've looked around in the usual places but no one seems to give easy to follow step by step instructions.

Many thanks

If you have not installed TWRP recovery, all you need to do is download this file http://www.ztedevice.com/support/eccd1567-5b37-4f94-b0d9-8000363ff831.html un zip the file and place it on your External SD.

then turn off the phone, Press Power and volume UP until it vibrates, then scroll down to update via sd card and then use the update.zip.

Thanks a lot, I will give that a try.

EDIT - The download is incredibly erratic. Flipping between taking another 30 minutes to download to taking 15 minutes. This is on a 37mb fibre connection.

That's pretty normal for ZTE servers tbh
