    Where do you find the file: " u-boot-SD.bin.mid703v3.mm" ? I can't find it anywhere.
    Thanks.

    Using Google returned two sites with direct download: 4shared and mediafire. Did you try those?

    Well its official. I have thoroughly bricked my brand new Kyros 7127. It started out as being stuck at the fastboot CWR screen, I was then able to get it to the FWDN screen, and read several tutorials on how to use the FWDN program to unbrick it. Well I was able to get it all set up with the FWDN program. I successfully flashed 2 of the files, and the tutorial said " After step 14 you could flash using the system image tcc8900_mtd..", so I figured it was optional and all I wanted was to be able to get back to a recovery screen and restore the CWR backup I had made. Well after trying to reboot it it now wont even go to the Coby screen. The buttons light up, nothing on the screen, and it stays like that until you either desolder the red battery wire, or wait until the battery dies.

    So at this point I have emailed Coby and have asked to have it shipped in to fix it. Im sure my warranty is null and void, but at this point I dont care. I just want it back to the way it was. :confused:

    You should never, I say again never, try to flash a firmware that wasn't tested on your tablet model. If you got FWDN running, maybe you can get a backup from someone and install. Or try to get ClockWorkMod installed so you can do it. I can't help much since I have never used any Telechips based tablet, so I don't know how to do it. But if you can get fastboot I bet you can flash a backup firmware.

    I was able to get in fwdn, but cant now, just blank screen. It does have clockwork installed, and I have a full working backup. But I have no way to flash it because I cant get into recovery. I also cant get into adb because my pc doesnt even recognize the tablet via usb.

    It seems that the problem is that it doesn't boot anymore, so u-boot is missing or broken. You could try booting via SD but since there is no restore firmware for 7127 it will be hard to do. You could try the CM7 beta for 7022, as it is already bricked. Maybe you can get fastboot back at least...

    There is no 2.3 and no official firmware for 1025_v4. You must use a custom one (CFW). The procedure works as long as you follow the instructions:
    - use a 4GB microSD for the resurrection firmware
    - use "u-boot-sd.bin.mid703v3.mm" as explained
    - copy a compatible firmware to the empty partition of the microSD used for resurrection
    - short circuit NAND pins 7 & 8 while booting for firmware installation if the tablet won't boot otherwise.
