I have a Huawei p8 lite which is a version of chinese dual sim .I got an OTA update couple of weeks ago and now bluetooth and the wireless options are not working.All were working perfectly before i update the ROM.I wanted to downgrade the installed firmware to fix this problem but i couldn't find a firmware which is supported for my region.I have tied with the European firmware but it was failed during the update as i expected. How can i downgrade it to previous official ROM ?Or at least how can i flash it with a fresh Rom.Are their any software available to flash it?Because normal Volume Up +Volume Down +Power button method is failed like it was failed when i try the European ROM.

  • Current build number is ALE-L21C636B170 and EMUI is 3.1
  • i checked European marshmallow Roms as well.Again it was failed.
  • I tried factory reset and wipe patition and etc before check with a Rom
