    Western Digital My Book 3TB firmware dump

    Hi All,
    Does anybody have / or is able to provide a dump of the U2 chip (SOP8) in the WD MyBook for MAC 3TB enclosure? Its the chip on the SATA to USB internal interface card.

    Background - I have an enclosure which was not functioning correctly. It was only providing 2TB of space as opposed the original 3TB, no matter how i formatted it. Disabling chip U2 (cutting pin8) restored capacity to 3TB however with the loss of the useful WD drive functions.

    Hence the desire to fix the enclosure by replacing the faulty U2 (25LD020 OP8) with a new one, programmed with a good copy of the firmware. Hence the request.

    nb my circuit board is marked 4060-705094

      Request HP Proliant Microserver Gen 8 (J06) BIOS dump to restore system firmware
      by Ahari
      Hi all,

      This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.

      I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

      I...

      Request for MX25VB8035F (1MB) Firmware Dump – Asus TUF Gaming H670-Pro
      by Tamo Neko
      Hello everyone,

      I'm working on an Asus TUF Gaming H670-Pro motherboard and need help finding a firmware dump for the MX25VB8035F (1MB) SPI flash chip.

      What Happened:
      I mistakenly removed and erased this 1MB chip, thinking it was part of the main BIOS.
      • I later found that the board has two main BIOS chips (8MB + 16MB), which I have backups for.
      • My backup for the MX25VB8035F chip is just an empty 1MB segment filled with FFs, meaning I have no valid data to restore.
      What I Need:
      • A firmware dump for the MX25VB8035F chip from the same motherboard (or a compatible

      DUMP DVR HIKVISION DS-7208HGHI-K1 (80389 Rev 1.3 Firmware)
      by Mephysis
      Hello guys i really need help, i recently updated my DS-7208HGHI-K1 and it somehow got bricked, I've got it up and working now by flashing a new dump file i found but the serial number is really wrong and the uploader of the dump file probably intentionally did it.

      I still have the bricked dump file is it possible to transfer the serial number of the "bricked dump" to the "working dump"?

      Need firmware dump for LG 23MP48HQ-P
      by gun4as
      Hello everyone, I have an LG 23MP48HQ-P with a mainboard EAX65543134. After a power flicker, the monitor only shows the "No Signal" message but goes to a black screen with a brief flash when an HDMI/VGA cable is plugged in. I cannot enter the OSD menu. All main voltages (18V, 5V, 3.3V) are stable under load. I made a backup of the firmware, but it was *after* the fault occurred, so my backup is likely corrupted. I flashed it back with no change in behavior. I can only find the firmware for the 24M38H model online. Could someone please share a working firmware dump for the 23MP48HQ-P?...
