    I have this tablet device, and I bricked it - it has no software and i cannot install any. The whole thing started when i tried to flash the device on Win2000. There were errors with RKAndroidBatchUpgrade and then I went to Win7 computer to flash it again, but with no success. I saw then a tool for flashing on Linux, from xda-developers, but it also didn't help.

    My problem is that, on Windows, if i use RKAndroidBatchUpgrade, it comes to step "Testing device..." and then it stays forever like that (flashing "0%" at the bottom). If I use RKAndroidTool it says either "Testing equipment... failed" or "Testing blocks", something like that.

    On Linux, If I follow wiki for unbricking rk2818 devices, and do commands like this :
    Code:
    $ rkflashtool w 0x00004000 0x00004000 < unpacked/Image/kernel.img
    $ rkflashtool w 0x00008000 0x00002000 < unpacked/Image/boot.img
    $ rkflashtool w 0x0000A000 0x00004000 < unpacked/Image/recovery.img
    $ rkflashtool w 0x0000E000 0x00030000 < unpacked/Image/system.img
    It is just staying with the message :
    Code:
    rkflashtool: info: reading flash memory at offset 0x00008000 
    Then, If i press reset on the device, it works, but prints some errors, like this :
    Code:
    rkflashtool: info: interface claimed rkflashtool: info: writing flash memory at offset 0x00008000 [stuck here, press reset] libusb:warning [do_sync_bulk_transfer] unrecognised status code 1 rkflashtool: info: writing flash memory at offset 0x00008020 libusb:warning [do_sync_bulk_transfer] unrecognised status code 1 libusb:warning [do_sync_bulk_transfer] unrecognised status code 1 libusb:warning [do_sync_bulk_transfer] unrecognised status code 1 rkflashtool: info: writing flash memory at offset 0x00008040 libusb:warning [do_sync_bulk_transfer] unrecognised status code 1 libusb:warning [do_sync_bulk_transfer] unrecognised status code 1 libusb:warning [do_sync_bulk_transfer] unrecognised status code 1 rkflashtool: info: writing flash memory at offset 0x00008060 rkflashtool: info: writing flash memory at offset 0x00008080 rkflashtool: info: writing flash memory at offset 0x000080a0 rkflashtool: info: writing flash memory at offset 0x000080c0 rkflashtool: info: writing flash memory at offset 0x000080e0 rkflashtool: info: writing flash memory at offset 0x00008100 ...

    I discovered that if i unplug USB cable from the tablet it is the same as if i have pressed reset, so it is not writing files as it says...

    I'm having the same problem with my ONDA VX580W, flash failed twice and now when i try to flash it, it sits on "Testing Device" and stays on 0% forever, Did you ever find a solution to this problem?
