Model: Lenovo y50-70 20378
Problem description: I downgraded it from ver.3.03 (bios) to ver.1.14, and tried to delete the existing module through EzH2O, then repaired and stored it.
Question 1: I used rufus to make a free and pure DOS system. I copied and saved the files saved by EzH2O to my mobile flash memory (U disk-it is already in DOS mode). When I booted up, I set up bios to make him It is in legacy mode, and then quickly boot into the DOS mode of the U disk, but a new problem comes, Error201: [fpt. exe】 cannot be run on the current platform, please contact your vendor.
Question 2: I tried to run CMD with highest privileges again in windows10 x64,
fptw64 -f biosbak. rom -bios but it didn't work again
The problem is that PDR region does not exist
GBE region does not exist
Error28: protected range registers are currently set by bios, preventing flash access
please contact the target system bios vendor for an option to disable protected range registers
I tried searching the materials for a week and learned how to use them, but the results are not the same. I am a little bit distressed. Is the tool incorrect?
This makes me very helpless, find our organization to ask, if you have time to guide me?
