ite8227e-256.

I have a programmer SUCCESSOR50+ite lite board. https://www.vss.store/magazin/produc...or-successor50
Technically I can flash this chip. I need only work dump.

This is an excerpt from the bios you posted..

How did you do it, I need similar help in the same way, thanks!
My machine is also 16IAH7H 82RF, MTM 82RF0000CD,SN PF3SFP32
Here are my files for the bios backup that won't boot due to modifying the Gear Ratio to 1 and the official website's bios that has no DMI information, respectively

I've done it. I found the two segments beginning with LENV and they are the second Padding partition shown in the UEFITool. Then I copied and pasted twice as many FF0h bytes of data through 010editor and all the DMIs were restored (this doesn't work in UEFITool by exporting the Padding directly and then importing it).

After updating my bios via the provided .exe on the Lenovo Website the machine ended up at the ROM recovery screen and is now stuck in a loop. Both options are ending at the starting piont.

The bios update startet normal and went relativly fast. At the end of the bios update the machine did a restart but never startet compleatly. Only the Fans are running at a high rpm speed and the keyboardlight works.

I already tried simple thing. Powerdrain, cmos reset and leting the machine with no Power overnight didnt worked. Iam unable to enter the bios via the F-keys.

post merged...next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

Don't post pictures unless asked..
post motherboard model,TYPE,etc.

post the contents of the bios chip even if it is corrupted..

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Motherboard: NM-E231 Rev 1.0

I found 2 winbond chips with the Numbers:
25Q16JWIQ
25R64JVSIQ

I found simmilar chips for example 25Q16V i the supported list from AS programmer.
My question is, is it posible to read these Chips with a c341 and AsProgrammer since bouth Chips arent supported or do i need another programmer and ore software?

manually select equivalent chips..

[m1ch43lzm]

25Q16JW most likely GPU VBIOS, don't touch that one
Main BIOS is split in 2 chips 25R64JV and another chip very close to it with 25*128 in the name, may be 25Q128JV or equivalent from another brand (example XM25Q128, MX25*128**, GD25*128** , etc)
For the 25R64JV select Winbond W25Q64JV or W25Q64FV
