32mb current not unlock

Good morning, SIr.
I have here a ThinkPad E14 Gen 2 (GE4B0/GE5B0 NM-D011), Core i7 11ºGen, but this machine has it´s BIOS locked. I removed WSON8 Gigadevice 25R256DYIG and changed firmware, but when I powered it on again, started a processing "SELF-HEALING BIOS BACK-UP PROCESSING". And this Lenovo recovered old locked BIOS automatically. So I can´t install Windows. SIr, I have original BIOS file here, could you help me get this situation solved? Thanks a lot.

Good friends, I have a problem with 2 laptops Lenovo ThinkPad E15 Gen 2 and has model motherboard GE4B0/GE5B0 NM-D011 Rev:1.0, the problem they have is that one of them when I press the power button the LED of the button flashes 3 times, it turns on and off after 5 seconds, It turns on again and repeats the process of switching on and off in a loop forever.
The power button does not respond to the off when pressed, the RAM has been checked and they are good and without errors; Does anyone know where the problem may be and which part of the motherboard should be looked at?
I have the repair scheme to go looking. Thank you very much and a greeting.

Thank you for answering, I tried a new BIOS and it did not work, it was taken from a working computer and same model and CPU, follows with the same symptom as above.
A greeting.
