    I have u8800 Pro. Original firmware was Android 2.2.2 . I wanted to upgrade to ICS (4.0) First I upgraded to 2.3.5 . Fine but I couldn't use internet nor the WiFi. So I decided for the upgrade to Android 4.0 . The upgrade failed at least 10 times in the beginning of phase Step2. I have USB Debugging ticked. What to do now?

    Please help.

    I was warned to choose ROM for 2.3 , which ends with 512. I took ROM
    U8800Pro V100R001C00B512G001(Gingerbread) Firmware has to be 512!!!!

    The most important advice for me was
    Make a “dload” directory on SD card root directory , Copy the “Step 1\
    dload\UPDATE.APP” and “Step 1\ dload\UPDATE_g.APP” to SD card
    I copied UPDATE.APP to SD card in dload folder but didn't rename the file into UPDATE_g.APP!!!! I didn't understand the instructions corectly.
    After that Settings/Storage/Software Upgrade

    The next step is without renaming UPDATE.APP.

    I didn't need step 3, because I don't speak Chineese.

    After that relevation everything went smoothly and problemless.

    After that upgrade to 4.0 went ok without any problem.
