EJTAG Debrick Utility v5.2
But I'm not sure is this program worked fine (I think wrtjp.5.2.exe not the best choice, because it has a lot of bugs). For example if you choose any option for chip "/fc:XX" with a capacity of 4MB, the program will be fine with them to work (read). Because of this, I think the problem with writing it in the Flash Chip in this "/fc:XX" command option.
I have MR3220v1.2 with cFeon F32-100HIP (EN25F32) SPI Flash-chip
TJTAG 3.0.2 RC3 readme:

As i understand the programs based on TJTAG not supporting the cFeon F32-100HIP (EN25F32) chip.
I tried to work with the program TJTAG V3.0.0 (it not supporting the cFeon F32-100HIP (EN25F32) chip) - but the program has not been able to determine the flash-chip (even for read). I was looking for a program version 3.0.1 or 3.0.2, but I could not find it (for windows).
I would be glad of any help or any links.
P.S.
Please forgive me for my awful English.
