Hi!

My Mygica ATV1200 working firmware was 20130805 (http://www.geniatech.com/news/dual-c...re-release.asp) but then i wanted to test older firmware and started to downgrade my box. I installed SPI from 20120918 firmware (http://www.geniatech.com/down-eng/an...0120917SPI.zip) and after this install my box doesnt boot anymore. It just showed the red light and i cant get to recovery too.

I compared both spi files: the spi.img file from working firmware has 3 files inside (env_MX.img, recovery.img and uboot_MX.img) but the older firmware spi.img file has only 1 file inside (spi_MX.img).

I tried many different rescue methods and one of them worked. With rescue SD card and pin shortening my box booted to recovery. Then i tried to install spi.img files from different firmwares (new stock firmware versions) but always get this error message: assert failed: format("MTD", "recovery"). Here is a screenshot: http://postimg.org/image/3o9zw1llf/

Then i installed Finless 1.4a ROM (boot_recovery.img and finless_14a.img installation was without any problems) and thought that now i can boot my box but... without pin shortening and rescue SD it's only the red light and no boot.

Maybe somebody knows why i cant install new stock firmware versions but can only install Finless ROM and spi.img from 20120918? Its something wrong with the NAND partitions or its incorrect ROM format? Why box cant boot Finless ROM (all files are installed succesfully). Something wrong with uboot? Any ideas?

Thanks in advance!
