Hello Sir,
I am using Huawei P8 Lite in Pakistan. Recently, I updated it to marshmallow as update was listed on Huawei Pakistan website.
After that update, my phone shuts down automatically every 30 or 45 minutes approx.
Please take notice of this and release a update to fix the issue.
Or please let me know the procedure to downgrade to Lollipop, I have downloaded the old firmware too from huawei website but in setting there is no option to access that update file from SD card as the same I done to update.
I acted as you said and was able to locate the update file but installation failed.

Hi Axmat, I have got something to ask you. Since I have updated my Huawei P9 lite to Emui 4.0, it is constantly on roaming, while normal data connection doesn’t work at all. Why does this happen? Do you think I need to downgrade Emui to its previous version? Thanks a lot, Valda
