[REQUEST] Sony Vaio SVF13N series BIOS Unlock
#1
Brick 
Hey guys,

I really love my VAIO Multi Flip but the fan makes me crazy. It just turns on to early. I think there is enough room for a higher temprature target for the fan. I have already seen some BIOS Mods from other VAIO Notebooks and there was a hidden settings where you could change the low and highlevel fan target.

Could someone just edit the BIOS that the hidden settings are enabled? Would be great if everything is unlocked.

Link to the BIOS download page: BIOS DOWNLOAD

Thanks in advance!

Is the attached bios file unlockable? (7zip file added .zip at the end otherwise it wouldn't let me upload) its from a SONY vaio - I am unable to make it work with the python script I get the following:

 python j-bios.py -v R1130VA.ROM NEW.fd

Hi!
I modify bios through H2OFFT-GUI-Wx64, i need to disable TDP lock. I modified it.
When i reboot after flashing the bios from windows, i got an error "insydeh20 secure flash error invalid firmware image". Current version of my bios is same as modified 1150VA. I dont know how to change, i put skip version check in flasher config.
What i need to do to flashing well?

Good afternoon, I am the owner of this device and with the help of an spi programmer I took a bios dump.
I tried to turn on amt in it and sew it back up, but it didn't work and everything remained as it is. I also tried to analyze the settings for accessing the hidden ones through IDA, but due to the paucity of knowledge, I could not complete the work.

I ask for help with unlocking hidden bios settings, enabling AMT support, and if there is a white list there, then disable it (I know the rules, but suddenly it will be easy).

I tried to enable these settings to install a new wi-fi ax210 board.
