          Check to see if you have lost any small components around the bios chip (eg capacitors or resistors).

                          Re: T470 bios needed

                          I got my t470 20HE corrupted in a bad flash (no boot).
                          The winbond is a 25Q80JV 8Mb chip, but all I see here is 16Mb files for this bios.

                          I used Neo programmer and a ch341 to read the bios.

                          Am i missing something?

                          is there a way to extract a bin file from a bios update?

                            101.4 KB is far away from a good read. Try again be more careful.

                              "25Q80JV" size is (1MB/8Mbit/1024KB) and it's a Wrong chip, search for another chip on the Motherboard (Both sides).

                                  25Q80JV is the most famous spi chip around here.
                                  I don't understand why rookies likes him the most, probably because of the number 80 on the marking.

                                  Yes it is, that's the right one. Are you using a clip to read the chip?

                                    They probably assume it will be 8MB. Also sometimes it has the same package as the BIOS chip (SOP8/SOIC8).

                                      I don't understand why rookies likes him the most, probably because of the number 80 on the marking.

                                      Edit:


                                      Yes it is, that's the right one. Are you using a clip to read the chip?

                                      .
                                      Yep, the full aliexpress package.
                                      Freezes sometimes in the beginning, sometimes halfway.

                                        Yep, I bet that's exactly why.
                                        Maybe it's time to put in my signature - "Do not touch the 25Q80xxxx chip"
