I think I got myself in trouble stuck on 2.75 - I cannot downgrade to 2.60 (X230) via IVprep or the lenovo tool (I get "This app can't run on your PC"). Is there a way forward, please?
Here is what I did and was planning to do (1vyrain, skulls and clean/disable/break the Intel ME): ## 1. EC Patching (accept all batteries and keyboards)
https://github.com/hamishcoleman/thinkpad-ec/ It recomends using on the last modifiable version: x230 -BIOS 2.75 (G2ETB5WW) EC 1.14 (G2HT35WW)
Therefore I upgraded from my 2.55 to 2.75, by downloading g2uj31us.exe, saving on a usb stick and running on the target machine's windows (the bootable iso would not dd well to the usb stick). https://support.lenovo.com/ec/en/downloads/ds029187 ## 2. Downgrade from 2.75 to 2.60 (X230) (I cannot perform from here onwards):
https://github.com/n4ru/IVprep/tree/master
Downloaded both IVprep and g2uj17us.exe and saved on the usb stick to run on target machine's windows but then I get I get "This app can't run on your PC".
I have tested with both: BIOS Setup -> Security -> UEFI BIOS Update Option. Set Flash BIOS Updating by End-Users to Enabled, and Secure RollBack Prevention to Disabled BIOS Setup -> Security -> UEFI BIOS Update Option. Set Flash BIOS Updating by End-Users to Enabled, and Secure RollBack Prevention to Enabled ## 3. Get rid of the ME
https://github.com/corna/me_cleaner I gues for this one, I should boot the target machine with a Live Linux, clone the repo and execute ## 4. Install Skulls via 1vyrain
https://github.com/n4ru/1vyrain
This would be burn the usb stick to the 1vyrain, use the ethernet cable and the skulls release URL https://github.com/merge/skulls/releases ## This question has been also posted on: - https://github.com/n4ru/1vyrain/issues/144- https://forum.qubes-os.org/t/how-to-use-ivprep-and-1vyrain-and-disable-intel... https://github.com/merge/skulls/issues/302 - https://github.com/hamishcoleman/thinkpad-ec/issues/266
