    P774a HKC
    Ok Well I need a little help Here is what happened
    I got my HKC Android P774a-BL Tablet ich Screen
    I heard the Usb Drivers Nexus work for ADB For this Device

    Well i rooted my tablet with China Version of RootMaster
    Success with ADA drivers
    After a while I got a infinite Wifi Loop Connecting Error B.S Check to see if it was still rooted and i was not able to assign privleges
    So i uninstalled Superuser and Supersu used the unroot button
    Retried rerooting it with chineese app and it went to a full back up restore said starting to restore then ir said restore ended with a X
    Tried many programs i think it was the SU binary So I downloaded
    the update from HKC Digital
    Decompiled the Image and it said P771A
    So i was wondering why putting the update.img in the sd card or internal memory would not work
    Update never started
    Then i noticed rockchip
    So i Downloaded Rock Chip Batch tool
    I installed the rockchip driver the HKC p774a Does not have any volume button
    Just a Home button Reset Pinhole And power on off
    So powered it off with the usb cable unplugged Pressed and held the HOME BUTTON
    and kept held while i inserted the USB and it was a blank scrfeen but it came up as UNKNOWN DEVICE
    So i installed the ROCKCHIP driver from the Rockchip Batch tool THe one that came with it
    And it did have no Denys every thing was notchiced as rockchip usb
    The Rockchip the tablet it uses is RK29
    Which is weird Well In the RockChip Batch screen there was a green LIGHT down at the bottom
    Under it was the numbers 4-5
    I opened up the update.img in the browse
    selected the green device which was my tablet clicked restore
    All because i wanted to redo the android because i could not fix the loop and i lost my root privs.
    For the loop problem i needed to change the read permisions to owner to the file DHCP or something of that matter

    Well after i clicked rester Do in mind the chipset said rk29
    everything was fine
    It said Varflash Was blinking got to %100 Percent and then said
    Check Chip FAILED
    I think it may have not been the right update
    But Now i tried pressing reset pin hole do everything to turn it back on nothing but a black screen
    I think i removed the rom
    Can someone recreate the rom firmware for this HKC P774A-BL 7in WiFi Android Tablet - 8GB Color BLUE P774a
    Network 802.11b/g/n DDR2 1.5 GHz Dual Core
    Website
    Code:
    hkcdigital/update/
    I uded the 8g version


    The device still works just wont turn on nothing but a red light when i plug in the charger and the usb shows up as rockchip usb
    Other than that nothing else works can someone please help me
    I am sure this will fix many other problems as well for other people.

    I wish you the best of luck, I don't waste my time on Rock Chips, they simply aren't worth fixing, but that's just me, perhaps someone that feels differently will come a long and fix your tablet, if not try ebay.
