Hi Andrey,
How did you interfaced the SOC,,
Have you tried the procedure mentioned below:

And how did you used the omapflash tool?

Yes, sure, I tried this method. But download mode also not working, because firmware full destroyed with bootloader. When I connect device system see it like connect/disconnect long time.

I used omapflash many times with different settings, but may be not with correct.
Command -
OMAPFlash.exe -v fastboot flash recovery recovery.img
not working.
I think need correct sample scripts for my hardware. See picture ( Elpida 8Gb). Or may be possible find special short pints on board?
What is files MLO and sbl.img? I can't find it inside stock firmware after extract. May be possible use usbboot with this files?
Thx for answer.
Hi Andrey,
MLO and SBL.IMG are the bootloader images. MLO is the x-loader or the 1st stage and the SBL is what i believe to be the secondary boot loader. I presume that the command for flashing the bootloader is
OMAPFlash.exe -v fastboot flash bootloader
<boot.img>

"Operation Failed" unfortunately. Drivers working properly. Just device connect/disconnect/connect/disconnect...
I trhink need make special script for this hardware something like this:
"-omap 4
-t 36000 -p OMAP4460_TUNA_8G_HS_PRO -2
chip_download EMMC@0 Targets\Projects\tuna\MBR.bin
chip_download EMMC@20000 Targets\Projects\tuna\MLO_4460_HS_PRO
chip_download EMMC@80000 Targets\Projects\tuna\sbl.img
command cold_sw_reset"
I am not familiar with the memory configuration for this device , but your approach is correct. What version of the omapflash are you using?

I am using any version with same result (4.16, omapflash-lnx also). But I think first need for update bootloader two files special for my model: MLO and SBL. Where can I find this files? I have only u-boot.img from stock firmware.
