Hi, I got a defective Kindle PW and want to try to fix it. Following the board's advice, I bought the TTL-232RG-VREG1V8-WE. Now I can connect through serial port to Kindle. Using Putty, I managed to run both BIST and Recovery Menu on this device. Unfortunately the problem is that after connecting Kindle to USB, the device is only available for a while in the Device Manager (Win10 Pro). I think the next step should be flash diag and main partition, but I do not know how to do it without access to the usb storage.
Please give me any tips.
