        24G256 - BR24G256
        Yes, you can, insert it into the block for eeprom. Select the microcircuit, then "I2C", then "Generic" and select _24C256.

            Do you still have the native, not working dump?

                  No, I need to dump his old native (not working), which was before the update.

                      The file (Dump), which you now want to read, has already been updated with an incorrect "cv306-merge.bin" file, but I need it before the update, the bin file can be packed into winrar.

                            How do you read dump? your dump size is very large, I asked you that you have an old dump left, the one that you did not update with the update.

                              sorry my mistake .i did not read the data before the update
                              the tv was fine but no sound ,after the umc update no menu or sound

                              i read the spi using ch341a the spi number is 25q328vsig
                              the nearest on the list of programmer ,i used w25q256fv
                              does that matter ?
                              im still learning as ive only used the ch341a a few times
                              i did try the update a few times ,could that be why the dump is larger than normal?

                                Is it native spi flash? There should be 25Q32 or 25Q64, but not like 25Q256.
                                And if there is no sound, this does not mean that the matter is in the firmware, there may be another problem in the hardware.
                                Do you have such a mother?

                                  this ic is the original
                                  it does not look like it was changed in the past
                                  its possible that the spi number is 25q32"b"vsig
                                  not 25q328vsig
                                  as the markings are so small ive used two magnifiers to get the best chance of accurate reading
                                  the pic looks similar but not the same
                                  the board markings are CV306H-X
                                  then the second number is 27T1005A D
                                  I should add the original fault was :the sound would be ok for a few seconds

                                    Count again, like 25Q32, and lay it out again, the size should be 4Mb.

                                          should i erase the spi with ch341a first?
                                          then load the fresh dump to it ?
                                          or should i refit the chip in tv then use usb to write fresh dump
