OK I have a DFu V3.29d Hardware v1.7B, MCUtype STM32F103VB, LCM Ctrl: ILI_9341 and seem to have every headache described in this thread.
I tried upgrading with the latest dfuse demo, but no devices show up. I tried installing from the 3.0.0 version, same problem. I tried doing drag-n-drop but the drive either disapeers or the attempt times out. I tried installing the driver over the defaulted on in windows (driver that came with the 3.0.0 version) but it always falls back to the windows driver.
I tried throwing dfu-util on two different linux based machines - I tried everything under the sun to get it to see the dfu devices with no luck.
I eventually found that on linux I could get the /dev/sd? to mount from root. I tried copying the two files in together, dismounted the partition, remounted and saw one reading RDY, the other reading ERR. I tried copying them one at a time - dismount/remount and saw RDY on each that way one at a time. I powered off and back on and had the white flashing screen.
I came to this thread and have tried again with the original two files twice (together and separate) and the patched version twice. I have tried grabbing a LIB301_APP311_2 suggested by one user, still white flashing. I tried grabbing DSO Nano 2.6 official firmware - still white flashing.
At this point I don’t care if I end up on some old version - can anyone tell me how to un-brick this thing please?
The dfu mode still comes up fine and the info mode still come up fine, and I can see the logo briefly before the flashing thing. Any help would be greatly appreciated.
