Possibly if you find the Lenovo tools somewhere. Some Lenovo bios updates for Thincentre ask for new serial, but I’ve seen Laptops updates mostly not asking.
I downloaded the bios 1 and bios 2 files that were posted here and bios 2 was successfuly loaded and the laptop is back to life!!
Thanks for the info, great forum
Hello everyone, I also updated the bios to a friend of mine’s flex 4 14ARE05 and I found myself in this situation. I purchased the CH341A programmer and I think I managed to read the inside of the bios, I attach it in the message, now what should I do? SN: R90YD&XN
Hey tnx, flex 5 sorry, the exact model is the flex 5 15ARE05 R90YD6XN (wrong serial in previous post), i updated with the latest bios on lenovo site before the brick (EECN44WW version). How can I compare the various dumps? I bought the CH341A programmer without the 1.8 volt adaptor, is necesary? Tnx
But the last EFI volume should be static firmware code and while all the structured parts of the firmware are EECN44WW the last EFI volume is not. I hope this is just static code and nothing gets changed when in use, but I can’t unfortunately check for older versions since versions earlier than EECN42WW aren’t available any longer.
So I replaced the last EFI volume, might work or might not work…
