Here's a tip for the Asroxk G10

After an installation of DD-WRT it was not easy for me to quickly reinstall the original firmware , bricked ?

I had wired the serial / ttl port

1 - You must use tftp to install OpenWrt ( see slh post )
2 - Once openwrt started use scp
3 - Copy partition 11 previously saved in tmp/tmp
4 - Flash partition 11 with mtd -> mtd write 11.bin ubi
5 - From openwrt run "g10_back_to_factory" script from /sbin "
6 - Power off , power on

If you don't have partition 11 you can contact me

Thanks for your reply, but I'm still not able to boot an Image which I transfered via tftp before.

After stopping the boot process, I've told u-boot:

Things I've tried:
Different LAN cable(s)
Resolder the serial console (this time taking GND from the JTAG header)
Back to OEM FW, upgarde OEM FW and install OpenWRT again.

I'm running out of ideas :thinking:

I just tried tftp-booting the FB-4040 from the .ITB image the same way, worked out of the box.

Any help appreciated.

That box was driving me mad ...
After loading the image via tftp I did a checksum calculation.
The output of tftpboot 22.03.3.itb was something like:
...
Load address: 0x44000000
...
Bytes transferred = 9161376 (8bcaa0 hex)

So I did a
crc 0x44000000 8bcaa0
After each tftpboot with the same file the checksum had changed :yawning_face:
WTF is going on ?

Next thing I tried was LAN Port 2,3 4 on the G10.
Same error on LAN port 2 and 3, only with with LAN port 4 constant checksums and the beast finally booted from RAM.

Is this just my device or do others have the same issue ?
