    LG 34UC87C-B X3 Firmware Dumps all EEPROMS

    Don't know if this helps anyone but have just dumped all firmware for the LG 34UC87C-B, moreover has anyone already dumped the firmware for this wide monitor and if so can they check if its valid, the one i'm working on has no standby but all checkable components check out okay.

    Have zipped and uploaded all three pieces of firmware.

    PCB = EAX65923705 Rev 1.0

    IC205 MX25L8006E
    IC901 25X40CL
    IC102 24C02RP

    If not i hope it may help someone.

    Quick question does the Firmware that is linked in that Post (for the 34UC97C-B) also work on the
    34UC87C-B or does it need a specific one (looking for IC205 FW)?

    Thanks!

        Re: Eeprom dump thread!

        In case someone is looking for a firmware for the LG 34UC87C-B which is bricked (no standby at all, appears completely dead), here is a dump from a know working one for IC205, which usually causes this behavior.

        PCB = LM43A | 34UC97C | EAX65923705 Rev 1.0

        IC205 MX25L8006E

        Other EEPROM ICs on board:
        • IC901 25X40CL
        • IC102 24C02RP


        Hope this helps someone!

            Re: LG 34UC87C-B X3 Firmware Dumps all EEPROMS

            Thank you omladinacm for providing the EEPROM.

            I flashed the IC205 of my LG 34UC87-B (pay attention: not 34UC87*C*-B) and it's working again. The only downside is that now Thunderbolt is gone (as far as I known that's the only difference between 34UC87C-B and 34UC87-B)...

            Not a big deal, as I'm not a Mac user and do not need the Thunderbolt - but of 'cause it also would be nice to get back to "original" condition. I'm afraid no one has a dump for 34UC87-B?

            Regards

              Was not able to fix my screen, but here the dump from my 34UC87-B.
              IC205 if someone needs it.

                Helped me recover my monitor. Re-flashed via ICSP using XGecu T56. Many thanks.

                  I was able to recover my 34UC87-B with this. As someone else mentioned, Thunderbolt functionality is gone, but I'm not using that anyway. Thank you!

                  ​Unfortunately this dump did not work for me. I suspect that it is corrupted.

                      Anker SoundCore 2 Bluetooth Speaker Turns Off After a Few Seconds (Possibly Firmware Issue?)
                      by zklgfs
                      Hi,

                      I have an Anker SoundCore 2 (A3105) that I saved from the trash (well, I guess there's a reason why it was supposed to go into the trash...). The problem is that it always turns off after a few seconds (sometimes it stays on a bit longer, between 30 and 60 seconds, but it still turns off). The power light turns on and the bluetooth light starts blinking, but both abruptly turn off again. The "turn off sound" is still played after the lights turn off. Sometimes, it also loops the on-off cycle several times without me pressing any buttons. If I connect an AUX cable, music...

                      Hello to everyone ,

                      This is my first post here, and i would like to share with you a small story in case you can help me.

                      Docker Type-C Gen 2 - Model 40AS. Was given to me by a friend for free ,but with the problem that you cannot use the video output ports.

                      All ports work , USB , Ethernet, Type C ... but HDMI + Display Port don't work

                      I searched on reddit and google for problem similar to that, and a LOT of people had fixed this problem by updating the firmware. So i tried , i searched and found 1.1.13 utility and 1.1.20 utility that can help...

                      Ubiquiti firmware help. US-8-150W POE
                      by gurj1979
                      Hi guys.

                      I've got a Ubiquiti US-8-150W POE switch which has issues with updating the firmware.
                      Turned out to be a bad EEPROM chip. It would read the firmware and work as normal, but failed to write new firmware to it.

                      So I took off the chip and read on EEPROM and saved it. Wrote to old chip and failed to write
                      Got New chip and writes good.

                      THE PROBLEM...
                      It fails to fully load the firmware, POE lights fail to work during g firmware test during load. I'm suspecting bad EEPROM Read.

                      Does anyone have a Good Firmware I can have?...

                      LG 34WR55QC dumps or firmware
                      by zzztann
                      Hello everyone,

                      I've been searching for days but couldn't find an EEPROM dump for my monitor. I tried flashing it using an MStar ISP programmer via HDMI, but something went wrong, and now the monitor is completely bricked—no display, no connection.
                      On board says 34WP75C Questions:
                      1. Does anyone have a working EEPROM dump for this monitor?
                      2. If HDMI is dead, should I try desoldering & flashing the chip directly (e.g., with CH341A)?
                      3. Any other recovery methods?

                      Request for EC firmware for MSI Vector GP66 12UHSO (MS-15441 ver 1.0)
                      by Slapito
                      I'm currently repairing an MSI Vector GP66 12UHSO laptop with a motherboard reference MS-15441 ver 1.0. The EC chip (ENE KB9548QF2) on the board appears to be damaged and needs to be reprogrammed.

                      Can someone please send me the firmware (EC/Embedded Controller) or indicate where I can download the correct EC firmware version corresponding to this motherboard model?

                      I already have access to the BIOS downloads on the MSI support page, but need specifically the EC binary or its equivalent firmware image.

                      I already downloaded the BIOS update file from msi official...
