Lenovo Flex5 1570 Bios

[clgr000ar]

Hi all,

I'm hoping you can guide me right after I accidentally cut off power to my Flex 5 1570 during an update.
When I now switch on, apart from the keyboard light coming on for a few seconds, and then going back off, nothing happens, and I cannot boot or get to the bios.
After reading various forums this afternoon, I've downloaded the update from Lenovo and extracted the bios (attached). I don't have a backup of the original bios.

Here's the Lenovo version

Where I'm confused now is with the following…

I've read below instructions to just put my newly cut Bios.bin in a USB, and try to boot, but have also seen several comments about people losing the machine serial number, windows key, wifi mac etc.

If I can get the machine booting with this method, will I be able to then extract the defective bios, and then edit and reinstall with the missing data?
Or do I need to get a CH341 programmer in order to recover this info first, before trying to boot with the new bios?

If I need to go the programmer route, do I need to solder, or can I just read out the data i need via usb?

Thanks for you guidance and Merry Christmas

Buy the CH341A programmer with a sop8 clip , make 2 backups first and compare them to make sure both are the same,then post your backup here.
There is a virgin bios in another thread,your serial and key can be copied to it from your backup https://www.badcaps.net/forum/showthread.php?t=71948

Edit: Use ASProgrammer,Colibri or NeoProgrammer software,you`ll find them all posted on the forum.The supplied software is trash

Hi again,

I've spent the past few hrs getting my head round getting windows to recognize the programmer and positioning the clamp so that it read the chip...but finally success.
I read out 2 copies with Neoprogrammer, and compared with Beyond Compare2..are identical.

In the zip is one of my dumped files, as well as the Bios and update files I made last week, in case of any use.
I'd appreciate it if you can help me put the pieces back together.

Cheers and Happy New Year

BTW, @SMDFlea is the merging of the defective and the reference Bios something I should be attempting myself?
