neomojo... did you get an answer or find a fix ?
I have the same 1016ui dvdrw 16x usb. I just tried to flash A087 to A187 with drvupdate.com/LiveUpdate and got the exactly same result : green led stays on after reboot and drive not recognised. Log shows:
Model Name : DVDRW USB 16X (1) HID : 3 TID : 0 Ver.: A087
Finished : fgWriteOneFlashCmdData()
Finished : fgWriteHeader()
fgTestUnitReadyComplete failed. 0/ 0/ 0
fgInquiryComplete times Out! Drive might be fail!
0/ 0/ 0/
Well, yes it did fail and no amount of recycling power brings it back -- even the tray won't open. Note I have done 3 successful flash updates before.
I've read quite a bit on this forum and visited and read the links from the DOS flash recovery thread, but the added complication is that it's connected to my laptop, so no access to IDE either. I think I'm stuffed !
