Lenovo X1 Carbon Gen 9. What the hell did they do?

[FeerBaron]

I am trying to enable undervolt and disable me engine. I read the bios from 2 hardware programmers and FPT. Inside FPT, all looks normal. From the HW programmers, the Flash Descriptor is shifted, nvram is encrypted? or missing and LNVSEC thing isn't visible. I thought my programmer was broken but that seem to not be the case..

Hardware Read Header

Normal header with FPT

Hidden header at 0x100000



FPT of course will not write the bios region despite not being read only and no nvram editing tools can write on live system.

Is this the end of bios mods ? Anyone see a flash like this before ?

For anyone else.. there are 2 chips, one is wson




Needs different clip and remove the black glue somehow.

Which 2 programmers did you use to backup with. It is probably the recovery bios

I used a Pi B and a SP8 programmer. Ordered myself an WSON8 clip (https://www.ebay.com/itm/395919546375) but now am concerned about getting the glue off the pins. They don't appear to sell the chemical to soften it in the USA anymore. It's neurotoxic and got banned. Maybe it will scrape off with picks but am not sure.
