Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hi all. Thanks to all for the help so far. However, I am not able to get a valid dump of my Yoga 460 BIOS. I have a CH341a with SOIC8 clip, but I can't get any dumb (not even a corrupted) from the BIOS chip. The chip is an MX25L12873F and supported by the standard software I use with the programmer. I don't want to desolder the BIOS chip, so I hope I can get away with the clip. I am still waiting for the SPI-Driver to be delivered to use my TL866 II. However, I was hoping I could go ahead with the CH341a. Any detailed...

Thank you very much! It seems I have to order it from China, as I can't find it at any shop here in the UK . May I ask you for a better picture of the wiring between SPI-Driver and the clip?

Would it work with a CH341a programmer and my clip straight away?

Sorry for asking all these noob questions.

Thank you for your help....

Hello,
I am using the TL866 II Plus programmer with a SOP8 clip to read the BIOS chip of my Yoga 460. Although the Xgpro 10.75 software autodetects the BIOS chip correctly as MX25L12835F@SOP8 it stops reading with an ID error. The software returns "Check ID Error! Checked ID is:0x C0 00 08".

When I force it to ignore the ID error and read the chip anyway and try to read the dump in UEFITool it returns "FfsParser::parse: not a single Volume Top File is found, the image may be corrupted."...
