WRT3200ACM corrupt bootloader recovery?

[panda-mute]

https://github.com/Chadster766/McWRT/wiki/WRT1900AC-corrupt-bootloader-recovery not work in WRT3200ACM.
Is there any method to reflash uboot of WRT3200ACM?

Follow the instruction in the below link in the Armada 385 tabs:

It seems the device not into uart boot stage? How to trigger the uart boot?

[Chadster766]

Try "./kwboot -t /dev/ttyUSB0 -b u-boot-a38x-spi-uart.bin " instead

Sorry I don't have Skype now.

Try as your advice:
Sending boot message. Please reboot the target...|
Sending boot image...
0 % [+++++++++++++++++xmodem: Bad message

Is there any help for this message?

[Chadster766]

That looks good but it fails in the middle of the uart transfer.

Check you TTL leads are connecting well.

[panda-mute]

The TTL connection is well, because it is working with another WRT3200ACM(input and output).
Anyway I change to another TTL to USB cable, the boot is hang, no uboot printout.
So can you advice which TTL to USB cable is work in WRT3200ACM?

I've asked the expert on this process to help with your boot loader recovery:
