    When I start my ZTE T77 at upgrading mode it returns the system recovery utility, but I can't flash the tablet. The reason is:

    E:Bad bootloader arguments
    "(null)"
    E:failed to mouknt /sdcard (No shuch file or directory)
    E:failed to mouknt /sdcard (No shuch file or directory)
    E:failed to mouknt /sdcard (No shuch file or directory)
    E:failed to mouknt /sdcard (No shuch file or directory)
    E:cannot mount /sdcard (No such file or directory)
    E:Can't mount /sdcard/factory_update_param.aml
    E:unkow volume for path [/udisk/factory_update_param.aml]
    E:Can't mount /udisk/factory_update_param.aml
    E:Error in /cache/recovery/last_log
    (Read-only file system)
    E:Can't open /cache/recovery/last_install

    otherwise I insert a bootable sdcard with factory_update_param.aml file with the .img file refered into its script is retourned the screen:

    E:Bad bootloader arguments
    "(null)"
    Finding update package...
    E:unknow volume for path [/install.img]
    E:Can't mount /install.img
    Installation aborted.
    E:Error in /cache/recovery/last_log
    (Read-only file system)
    E:Can't open /cache/recovery/last_install

    I've tried set rw to system directory by the adb shell us command prompt and that didnt work.

    Please can anyone tell me what to do definitely?

    Thank you!
