Marvell AQC113C FourPartID Firmware updater edit

Have you tried using the "flashUpdate2 --recover" option by chance? Does that save the contents of the flash? I ordered a ch341a, so I'll see what I can do with that and see if it can back things up without desoldering.

i just tried its to recover a bad card
e.g. you flash an image to it not save

Okay, thanks for confirming it's a write operation not a read operation. It's too bad they don't have backup options like many of the other flashing tools.
