    Bios read help fot HP 830 G5

    Hello,
    I would need help for reading a bios on 830 G5 .

    No desire to retire the chip and I tested with wires on TL866II

    but I can’t read it . this is a MX25L25673G

    It’s not recognized by the programmer.
    Chip id not correct and Full FFFF in read .

    I took the advice here with the charger but no better.
    https://www.badcaps.net/forum/showthread.php?t=79911


    He didn’t make it.

    An idea, an advice please

      I don't think 256Mb chips are supported by that programmer.

      I used raspberry pi + latest flashrom for that size.

          but chip id is always wrong .


          read is not full ff.
          somebody confirm the read is ok ?

          you can confirm that the HPUnlocker software works with 830 g5 ?? Please

              The MX25L25673G is in the support list. I have the older tl866cs ,i get errors like that when a chip isn`t seated properly in the adapter or zif socket.

                  Ok, this is the clip that falsely reads, I solder directly


                  This is why, you must always control its reading.
                  I really don't like the eprom clamp

                          What sort of clip do you have,a cheap one or a pomona.Its always more reliable desoldering the bios

                                          the chip was soldered directly to a programmer support, I no longer use the clamp

                                                  Hi everyone,

                                                  I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

                                                  I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

                                                  After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

                                                  I have desoldered the bios chip (GigaDevice...

                                                  Hi, my laptop wont boot at all
                                                  With original bios no POST, only LED lights
                                                  With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                                                  Some issues
                                                  A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                                                  B- If updated from 500LN version 203 to 300, the battery stops being recognized

                                                  Things I tried

                                                  by zenius
                                                  Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                                                  Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                                                  Hello,

                                                  I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
                                                  So I thought it was a Bios problem.
                                                  I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
