    Hi there will this work on the ALE-L02 ?

  10. Thanks a lot for your help, it really worked great for me. I struggled for a long time, from unlocking the boot to getting fastboot to detect my phone, it was a nightmare. With fastboot i realised i was using an outdated version of the driver.
    With unclocking i used a method i saw on youtube, i got the lock key instantly instead of that 14 days waiting period nonsense. You are a start man, give than man a bell!

  11. Hi sir i did the flash wrong firmware i can’t enable sim cards it failed no network imei is null,when am trying to update to new version manual it failed.

  12. My Phone shows error “failed to enable sim card”. How to solve this, I have Huawei P8 Lite ALE-L21. Please Help.
