It worked! But it was not easy... Clearly not a work that you are supposed to do as a lambda laptop user. Some feedback if it can help some dummy users like me: For the BIOS update, you have to go into one of the four /BIOS/FlashUtil/Afu* subdirs and run the exec file named something like GMxPX7xN109MED06.EXE. How to decide which of the four subdirs to use? No idea, I choose the win one without the _CAP at the end because Windows is my OS and I don't know what this _CAP is for... if someone can tell us, it could help futur users having the same problem. For the EC update, you have to follow Valleron's guide to the letter. I used this EFI shell and followed the instructions we can find on the page (mainly put the file in /efi/boot/ on the USB stick near the /BIOS and /EC dirs and rename it as explained). I was not able to chose my boot device using F7, so I went into the BIOS settings (F2) and changed the boot order in the boot section. To be able to do something when the EFI shell is available after booting on the USB stick, you need to switch to a file system. For me it was fs0 (the first item of the list provided on screen before the shell or returned by the map -r command), so I typed FS0: and was then able to navigate using ls and cd commands until I reached the F.nsh file that I ran (by just typing its name). To get access back to your Windows partition, you will have to enter your Bitlocker key that you can find on your Microsoft account. I think that you can also save this key before starting the update process by saving it on a USB key or even printing it from your Windows settings, there is some tutorial on line. If you don't know what is your Microsoft account credentials (eg. because you did not install windows yourself or you don't remember what you did), I think doing that before starting the whole update process is a good idea, this key cannot be recovered elsewhere and at this stage, you have no access to your Windows anymore to check what mail address you use to create your Microsoft account. Yes, this is help for dummies like me 😄 Now, I can play Heroes of the Storm without any freeze and can only blame myself for my defeats!
