Title: Bricked SoC ? Stuck in MaskROM mode, unable to update firmware [Print This Page] Author: sylvainsab Time: 4/23/2024 23:43 Title: Bricked SoC ? Stuck in MaskROM mode, unable to update firmware I hope my mistake can be repaired. Some weeks ago I seemingly bricked my RK3399 SoC, because I followed an advice from some internet tutorial advising to erase some blocks using an upgrade_tool ws 0xsome_address /dev/null or something like that. It was a rather small address.
Since then I can only boot in MaskROM mode, but what worries me the most is that the size of the flash memory is displayed to be zero :
sudo ./upgrade_tool rfi
Flash Info:
Manufacturer: SAMSUNG,value=00
Flash Size: 0MB
Block Size: 512KB
Page Size: 2KB
ECC Bits: 0
Access Time: 40
Flash CS:
Copy the code
Also I cannot simply wipe out / upgrade the emmc firmware like I used to do :
Program Log will save in the /root/upgrade_tool/log/

Is there a way to solve this and hard reset the SPI/emmc ? Probably using the electric pins ? Thank you.
PS I don't mind which platform to use, this is posted from Linux using manjaro live usb but I have a spare Windows computer among others.

Hello ? Can anyone tell me whether I can fix my own card, or else if I need to return it to the staff for repairing ?
