Hi there! I’m having some problems with some Dell Wyse 5070 ThinClients. We have a lot of clients laying around which need, according to the blinks of the orange LED (3 Blink, pause, 3 Blink = BIOS Recovery image not found), a cleaned BIOS. I have dumped the BIOS from a fully working Wyse 5070 and flashed one broken Wyse 5070, but unfortunately, it didn’t really work. The LED is white which means it’s powered on, but as soon as it gives output to all USB ports, it blinks orange again. What should I do in this case?
The chip is a Winbond W25Q128FWSG, 1,8V. The service tag is: B9N45P2.
Not all of your machines may have a firmware error, not all may have the same error. Might be corrupted static bios parts, corrupt ME/TXE, might be corrupted NVRAM, might be defective hardware or a combination of all.
Since there’s not much feedback on earlier threads no general recommendation. Easiest way would theoretically be to dump one machine, create a ‘universal’ stock firmware image with clean ME/TXE and then transfer the machine specific DVAR region for each machine.
Missing here unfortunately the proof of concept.
