                HI friends,

                I really need help because I am a little bit desperate. I am trying to fix my son's computer because we cannot afford to buy another one.
                I have desoldered de Wson8 (25R512JVEN) Bios Chip, however I am not able to read it with CH314a programmer (Neoprogrammer, Ch31A program, AsProgrammer...)
                Also I have modified Ch314a programmer 3,3V but same result.

                I attach you some pictures, I don't really now If I am doing anything wrong.

                Please help

                    Computer Details:

                      you have three different files because you read them with errors..
                      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..

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

                          The 3 files should be identical, otherwise you are doing something wrong.
                          What is the chip number? Need to see which adapter do you use with the Programmer?

                            25R512JVEN and I am using T48 programmer and Wson8X6 adapter. (Forget previous pictures of CH314a... in this thread).
                            I think i am doing well but unfortunatelly this chip is corrupted.
                            So I need a bios to write in a new chip

                              Here is your new BIOS, try it and let me know.
                              If you want to replace the chip, I think you need to use a similar one "25R512JV". Also you have to choose verify after programming the chip to see if the written file is identical or not.

                                  Hello everyone,

                                  First, the data in brief:
                                  Manufacturer: Lenovo
                                  Model: ThinkPad L15 G3 21C3-0016GE
                                  motherboard: LG4 LT5 ADL RT UMA MB 8L - 448.0PZ26.0011
                                  IC Bios 1: MX77L25650F
                                  IC Bios 2​: MX25L25673G
                                  EC Chip: NPCX997KAABX

                                  So far I've been a silent reader, but now I need your help

                                  I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
                                  I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele...
                                  The laptop was brought in with a BIOS problem and a password. After reading the dump, the information was damaged. I ask for help in the BIOS with a clean ME region. Motherboard 213035-1. Serial number: PW+04e998, Type number: 21c3-0016ge

                                  Should I buy a Lenovo Thinkpad E495 with bios password?

                                  Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

                                  I have a few questions:

                                  Thinkpad X1 Yoga Gen 3 ,How to know if the BIOS is corrupted

                                  Hi everyone, hope everyone's having a great day.

                                  I have a Lenovo Thinkpad X1 Yoga Gen 3 for repair. (20LES3T900)
                                  I looked in every corner and the laptop seems fine. Its pulling 500mA but no display, no noise, nothing.

                                  So I assume its a BIOS issue. I downloaded the BIOS with CH341A and opened it on ME Analyser and didn't receive any errors.
                                  Does this mean the BIOS is fine? making it a hardware issue?

                                  I downloaded fresh BIIOS from the Lenovo site and used Hex Editor replace the Lenovo's BIOS into my BIOS region. But the file size ended up being...

                                  3. Shutdown (no power) and upgrade WIFI with unsupported chip (AX210)
                                  4. Boot up the device : bios warning, as expected
                                  5. Shutdown the device again (no power)
                                  6. Connect the 8-pin clip of a CH341a
