Re: ThinkPad X1 Nano (20UN) bricked
Just wanted to let you know I managed to fix the laptop by taking the dump you posted first and replacing the individual ME partitions with the partitions from my secondary chip dump.
I also reinserted the product key from the Windows registry into the BIOS NVRAM, so automatic activation should work again as well.
Any idea which role the OA3 ID has regarding Windows activation? Is it tied to the product key?

ThinkPad X1 Nano (20UN) bricked
Hi guys,
while trying to mod my ThinkPad X1 Nano (model 20UN) I got too impatient to hold the wires pressed to the SPI Flash contacts, so I soldered wires to it, but wasn't paying attention when connecting my programmer and, stupidly, swapped VCC and GND. Thus I fried the main SPI Flash, and I only have an incomplete/corrupt dump (u49_incomplete.bin). The secondary SPI flash on the board (W25Q256JVEIQ) seems to hold two redundant copies of the EC firmware (at 0x1000 and 0xc0000) as well as a redundant BIOS copy. I am fairly confident that the secondary Flash dump is correct (dumped...
