    Check with the supplier to see if this is a Haipad and if the mainboard is from CBS (创必胜), or something else. This at least helps figure out what firmware to use.

    I found the reset button on the S22 (HW-701T), supposedly inside the mic hole..but how do u restore the firmware using the reset button?...( i hv unsinstalled the default built-in launcher). What is hte combination press sequence of buttons?

    What the the manufacturer's website?


    Having the system firmware (downloaded above), How do I get into firmware upgrade/restore mode? USB degugging is not enabled within.

    it is the fake 2.2
    unfortunately no solution for you.

    it is very easy to flash the firmware. Same as M701.
    To get into FWDN mode push and hold the Power button and the right button on top for 5 seconds. Add lk.rom, app.rom and splash.rom to fwdn and start.

    At my s22 the nand was erased by several experiments, so FWDN told me nand has to be formatted first.

    for the problem with the sensitive touch I use a stylus, that works much better than fingers.

    guys please help me. I upgraded the firmware went on haipad.net but I must have mounted the wrong one ("Haipad M701 Android 2.2"). Now the tablet should not be more. I'm not even from the possibility of starting with the boot. What should I do?
    Please help me.

    Use xp and boot your pad with pushing on/off button and the button return(at the right bottom) for 5 sec, then plug to pc with xp and flash it
