A further note for you guys:
1. This guide does not work for C782 devices or other country branded devices. It will work if you rebranded to C432.
2. These files are official, just been hosted on a third party mirror and Androidhost.ru is well known for uploading all service firmwares for Huawei and other smartphones.
3. If you got an error, either there is a problem with how you set the files up on the USB. It should look like this:
CLT-L09 or L29_hw_eu
Happy flashing guys!
