Unfortunately your file not working. Original file is ok. I have tested it.

Should work, most probably you didn't programmed the chip properly (with verification) or didn't solder the chip as it should.
Try again.

I reflashed the chip. Verified ok. Now working just high ventilation in factory mode which was confused me. Everything okay now. I'm happy that you erased the service tag region also. Very good work. Many thanks

You need to dump your bios chip content and reflashed the chip using patched content. Master password not available for free.

There are plenty of demo videos available in the Youtube.

If you haven't purchased the programmer yet, i would highly recommend the upgraded version which has proper volt setting is available. Older black PCB one is not that reliable and need a hardware mode to make it compatible with some chips.

In my experience, CH341A is a very reliable SPI programmer. What gave it a bad reputation is the usual way of using a clip to read the chip on board. This is a very unreliable method with any SPI programmer - even with costly programmers, reading and writing with the clip is a headache.. If you have good soldering skill, desoldering the chip and use a compatible SPI adapter is the best way. Otherwise you can try with the clip. In any case, you should read the chip multiple times and verify the checksum of all.
