Lenovo Carbon X1 9th(20XW). Failed to recover ME firmware.
Hello. Customer tried to update BIOS via Lenovo software. Update has been failed and unit was dead completely. I found working BIOS dump and flashed it. Now unit turns on very slowly, and, after every booting it tries to recover ME firmware and fails everytime. Also, unit can't detect nvme disk, so i can't boot windows to flash ME with Lenovo software. Can someone provide to me 100% working dump? There're 2 flash IC's: U49 and U801. I flashed only U49. Thanks in advance.

Re: lenovo thinkpad l14 gen 1
noone can help you. to unlock svp, you should reflash EC or modify EC firmware. currently there's no good and stable methods.

Re: mec 16xx dump with info block
hey, guys. a small question about service information. i was able to reflash eeprom area, but now i need input some data to eeprom area via UEFITool. for instance, i can't type correct "Machine Type and Serial number". also, "Product name is invalid", that's what startup sequence telling me every time i boot. if someone can explaine this issue, it would be nice.
