Huawei G7-L01 Change Vendor and Upgrade to Marshmallow (Europe-Asia)

After lots of searches over internet finally i have found a way to upgrade Huawei G7-L01 asian and European variants. Currently there is no official marshmallow update for these both regions. But in this post i will guide how to convert your phone region to turkey and upgrade to marshmallow.

Note: This process will convert your asian/european phone vendor info to turkey

 

Steps to Follow

  1. Unlock bootloader (how to unlock bootloader?)
  2. Backup important data.
  3. You must be running stock lollipop rom
  4. Download vendor update file from This Link
  5. Extract downloaded file and copy “update.app” file in “dload” folder on your sd card. if dload folder is not there, you can create it by yourself.
  6. Go in settings > update > local update> select update package. and install this file. if it fails then use forced update method (Switch off phone, then volume up , volume down & power press and hold them until you see update screen)
  7. Now dial * #* #2846579#*#* and then tap on project menu then network information and then tap on operator info. if it shows  Operator:Hw , Country:tr then you have successfully debranded your phone.
  8. Now download turkey lollipop firmware from This Link and install it following same step as you did in 6.
  9. If installation goes successful then follow This Post to install Marshmallow

If you want to rollback to european version download & install This File
