How to save bricks

The burning tool has been stuck at 3% after a short electrical contact, and uboot failed to load uboot. uart displays ddr loading failure, how to remedy it, and whether it can be forced to boot from SD.
Directly connect to the power uboot output:

Try this, and if it dont work with the firmware .img use the recovery.img out of the sdcard.zip firmware from Beelink. I have had to use the recovery img just to get to recovery and factory reset and so on from there.

Thank you, but it still doesn't seem to work. I accidentally formatted /dev/mmcblk0 before, and then restarted and it was a tragedy.

I may be way off on this, but i found something for a different box that just might give you a 'starting point' on how to go about it... hope this is of some help!

Thanks, but I still can’t forcibly flash the machine. I think the ddr initialization file is stored in the emmc of /dev/mmcblok0, and the firmware cannot be flashed without completing the ddr initialization.

Here is another discussion that might give more ideas ...

https://discourse.coreelec.org/t ... nternal-memory/1452

AND google around for that "2 pin shorting out" that would match exactly to your specific SoC chip and board ( i never have had to go that far )
Good luck

If you can enter into recovery mode that means you can flash a fresh copy of the firmware and the os but from the error i feel it is an hardware issue or maybe your flashing the wrong image.

Sorry for not replying in time

Please provide your series number
and which firmware have you updated？
