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 :
  1. sudo ./upgrade_tool rfi

  3. Flash Info:

  5.         Manufacturer: SAMSUNG,value=00
  6.         Flash Size: 0MB
  7.         Block Size: 512KB
  8.         Page Size: 2KB
  9.         ECC Bits: 0
  10.         Access Time: 40
  11.         Flash CS:
Copy the code

Also I cannot simply wipe out / upgrade the emmc firmware like I used to do :

  1. sudo ./upgrade_tool uf ffly/stock/FIREFLY-RK3399_Ubuntu20.04-r240_v2.5.1d_230330.img
  2. Program Log will save in the /root/upgrade_tool/log/
  3. Loading firmware...
  4. Support Type:RK330C     FW Ver:8.1.00   FW Time:2023-03-30 16:11:48
  5. Loader ver:1.1a Loader Time:2023-03-30 16:11:20
  6. Download Boot Fail
Copy the code

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 ?

I opened a thread on r/SBCs.

rkflashtool on MacOS gives the most information: this is what I get after having booted the card in Maskrom mode and attempted to write/update the emmc:
