    Eprom dump versus firmware update

    Hi all,
    I have a interesting question but does anyone know the following.
    If i flash a tv with a firmware update and then i remove the memory ic 25Q32BVSIG, a 4mb SPI chip and read the contents with my programmer and compare the two image files (Dump versus firmware) are they going to be identical.
    What I want to get at is that if I have a firmware update and I try to download it directly into the SPI chip will it be successful? Will it work. So far I never tried it because I assumed it will not be the same. Anybody know?

    Regards

      Firmware updates are different from the content on the 25Q32. It wouldnt work if you put the firmware directly on a 25Q32 or vice versa.

        I thought as much. Thanks for confirming my suspicion.

        Cheers

          i think you forget some "?", can you repeat? Anyway an update is almost never the same as a dump, because an entire firmware is comprehensive of every partition , the boot loaders (preboot, boot, etc..), the kernel, system, recovery, etc., an update can be only the main software update..

            Yes Davi, my grammar sucks. My english teacher thought so too. ��*♀️
            Over the weekend i got in a tv that needed a eprom dump and i could not fix it because the unit i was working on is so uncommon.

              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"?

              ThinkPad X12 Detachable Gen 1: keyboard after firmware update without function
              by rumpumpel1
              Lenovo System Update offered me an update for the firmware of the Folio keyboard for my X12 Detachable Gen 1. The update got stuck and after 20 minutes I switched off the laptop. Since then, the keyboard and touchpad have been without function. Does anyone know how I can revive it?

              Sony KDL-46HX850 Can't upgrade/update firmware
              by dkneyle
              Diagnosed this TV as having a failed main board which I've replaced with one from a KDL 55HX850. They are (supposedly) the same board.

              Being 'Smart TV' it requires a firmware reboot when you swap out boards such as T-Con or main board. It starts with a black screen and flashing yellow and green LEDS, indicating it needs that firmware boot. The procedure described all over the web is to put the software into the root directory of a FAT32 formatted USB drive and it should load that up once plugged into USB1 port. But not for me. I can see the LED on the USB chip flash for about...
