Factory reset after software upgradeSupport

    My M835 originally had the Build 622 software installed (B622 at the end of the version number). It has since been upgraded to Build 666 (B666) that was provided via Huawei's web site.

    If I do another factory reset of the phone, will the phone revert back to B622, or will it reinstall B666?

    The upgrade directory and files for B666 remain on the SD card, I did not remove them after it was upgraded.

    Thank you.

    Thanks. It didn't solve the reboot issue though. :(

    I don't get the reinstall issue?

    If you factory reset it will go back and reinstall B666 (Devil's in)

    I'm no longer using the M835. It rebooted too many times with no solution available.

    I will not buy anything made by Huawei anymore.

    I did enough resets of that phone. Trust me. I will NOT buy anything Huawei anymore, period, end of story. :mad:

    The phone was rock-solid when it had a native metroPCS signal and the roaming selection was on "MetroPCS Only." Otherwise, it was doing "The Reboot".

    Glad I'm rid of it. :wavey:

    My wife's cousin has this phone and has a problem with the phone crashing and rebooting itself when the phone is idle. It doesn't do that while the phone is in use, however, so what he does to circumvent the problem is to leave an app like his music player or something running....

    I noticed this as well when the phone was roaming on Sprint. I web browsed for a solid hour and the phone did not reboot. It only rebooted when it was idle. I suspect there is a software issue with the M835 that causes it to reboot like that. Even the update Huawei made available via their web site (I call it the B666 update), did not fix this problem. A friend who is a Linux engineer believes it is a device driver problem.

    My phone is running on Android 2.3 . Now I upgrade it to Android 4.0. I don't sure after I reset to facotory mode, my phone will turn to Andoid 2.3 or Android 4.0 ?
