I need a firmware vor a Coby Kyros MID7022-4G.
Dont know the build version, because it doesnt start.

On mainboard ist written EM73_M7

I tried the 7022 und EM73 FWDN-Images from: //
The 7022 and the EM73capazitive..8K results in an CRC-Error while flashing
The EM73capazitive..4K was flashed but System reboots an starting System.

I tried catdroid, D703, M778, whatever I find ...

Since fastboot is now working, I also tried to flash a recovery via this.
fastboot boot xyz-8k.img says "Incomplete Bootimage" and flashing will result in fastboot, when try to start recovery.
fastboot boot xyz-4k.img will reboot and flashing will also result in reboot, when try to start recovery.

It seems to be a 4K-Nand, because all others will result und CRC-Error/Incomplete_bootimage, but the ist a modul named EM_a100_v2 with a 29F32G08CBACA-Nand an that's an 8k-Nand.

Could anyone help with another idea or even better with a firmware for that build.

For further user who has problem with CRC error, the only solution that I found is replace NAND IC with 8K...

@sks4u Bro this NAND 29F32G08CBACA is 4K but board EM_A100_V2 is made for 8K... That is why we get CRC error..

I put NAND ic 29F64G08CBAAA and ALL WORKS OK after flashing with concorde7020_0712...

Best regard!!
