    Is it normal in those Samsung NANDs if there are 60-90 thousands (!) of bit errors? I know it is less than 1% but it seems like fairly unstable.
    You will erase nand and show log programmers where the physical ones are and how many bad blocks (BB) are at which addresses. I don't need your dump.

      Sadly it looks like the FlashCat Mach 1 programmer doesn't provide detailed information about the bad blocks:

      What should I do? I didn't find any log files in the program files / FlashCat folder.

        There can't be that many BBs "Total bad blocks: 1,467."
        Erase completely and check again.

          Here is an approximate programmer log for bad blocks, indicating at which addresses they are located:

          Request for bad blocks...Normal
          Number of bad blocks: 6
          Block 0x000D (13) address 0x00D00000 (0x00DB1200) Bad block
          Block 0x057B (1403) address 0x57B00000 (0x5C5ABE00) Bad block
          Block 0x058E (1422) address 0x58E00000 (0x5D9AEC00) Bad block
          Block 0x0645 (1605) address 0x64500000 (0x69A6C200) Bad block
          Block 0x06BE (1726) address 0x6BE00000 (0x719DCC00) Bad block

            I'll try to find where it logs the BBs list. Or is it not worth that because is it a highly damaged NAND beyond 'point of no return' ?

              No official BB list produced, so I managed to wrote down the BBs from the programs graphical interface. It is not less than 1455 (picture):

              2-13, 137, 215-377, 471-497, 499-510, 512, 514-518, 520-522, 524-532, 534-535, 537-561, 563-568, 570-584, 586-619, 621-626, 628-632,
              634-640, 642-699, 701-753, 755-768, 770-790, 792, 794-835, 837-847, 849, 851-896, 898-916, 918-959, 961-1024, 1026-1051, 1053-1106,

                Re: Eeprom dump thread!

                But there cannot be so many physical Bad Blocks, it can be the remains of a dump and in it these BBs or the programmer considers them as ECC.
                Try to thoroughly clean all the legs of the Nand Flash from flux, rinse it in isopropyl alcohol and acetone, here you need good contact between the legs and the adapter itself.

                  I did it initially before I did anything (fiber glass pen + isopropyl alcohol), but I'll give it a second chance. Now I did it again.

                  Something I don't understand: when the software recognising the NAND the message is "loading NAND memory map for valid memory, total bad blocks: 1455". And when I fiddled with the "Analyze" button in the "NAND memory map" menu, a window popped up with "Warning, this operation will erase and overwrite all blocks, continue?". Yes, of course and the process finished less than a second and then the displayed green-black blocks changed to yellow with a question mark in them, and the title says "NAND blocks analyzed (0 bad blocks found). But if I redetect (reinitialize) the NAND, the number of the BBs remains 1455.

                    Re: Eeprom dump thread!

                    Yes, it’s strange here either the nand flash is completely dead (try to find exactly the same used or new one) or the programmer does not understand the algorithm of this nand, I have never had more than 10 physical BBs in this NAND.

                      I think the software is buggy. After I turned off the bad block management and erased the NAND and activated back the BB management, the number of the bad blocks decreased to 7. I really hope this is their valid number.

                      137, 657, 1943, 2033, 2039, 2040, 2074.

                        Yes, now it looks more like the truth, but for some reason the BB at address 2073 is not shown, it is present on everyone, even in these new nands.

                          Interesting. What if we take it as bad, that won't be a problem if we don't write on that block, isn't it?

                          Edit: As I found I can manually discard blocks as bad blocks, so I discarded the 2073.

                          Edit 2: It is just temporary so not written onto the BB table. After I redetected the NAND the manually disabled block disappeared. Or maybe I did something wrong.

                            This is what happened under your BB.

                              In private messages there is a link to your dump, write it down as is (without missing BB!).

                                Hi Lotas, I have this Roku 43" TV that the standby light is on but do not respond to power ON, I replace the CPU with a good one from a similar good board of a 32", problem was the same then I put the NAND from the 32" and the 43" turn ON, backlight turn ON, respond to remote control but no picture, then I read the original NAND and programmed on the new NAND, now the TV have stand by light and does not turn ON, I suspect those Roku TVs are reading the CPU serial number so they do not work with a new CPU, here are the 2 files:

                                  Software/firmware is 1st step then hardware.

                                    Re: Eeprom dump thread!

                                    Hi. I am looking for the firmware for an RCA RLDED4031A-RK (Canada). Main board TP.MS3393.P85.

                                    EEPROM: 25Q16BSIG
                                    Right now the TV just has the red LED and does nothing else.

                                      Post your non-working dump here, I'll take a look and maybe I'll fix it.

                                        The TV doesn't even come on, only the red LED is On. I have no way to get the dump. At least not that I know of.

                                          How are you going to program someone else’s dump of your flash, do you have a programmer? If there is, read the contents of your flash and post it here.
                                          If it does not go into operating mode, then most likely your firmware is damaged, you read the contents (dump) of your 25Q16BSIG and show it to me, I will restore it and it will be operational and then you will download my corrected dump and your TV will work again, when provided that the problem is in the firmware.

                                            Hello, This might be a long shot, but I'm looking for an EEPROM dump for a HP Photosmart C4280 All-in-one printer.

                                            The printer seems to be in cartridge alignment mode. Sometimes it print the alignment page and then hangs during the scanning step, sometimes it hangs during the printing process and sometimes it hangs during the boot process. If I let it idle for a while then it flashes the back-light of the top screen and there's a letter E. Bottom screen is asking me to restart it to no avail. I have to remove the power cable from the printer for a couple of minutes to make it work...

                                            Hi

                                            I was working all day on a 42" with no backlight = Driver is bad . LED Tester. Image exists

                                            As I was reassembling, I discovered faults on the screen ( used the LED Tester to power the strips).

                                            Right distribution board, 2 Flexs, near them:
                                            The one near the center has 1" line on screen. Pressing on the board-side or Panel side of the Flex bonding place results in some change, I sensed heating one time, but main fault line remains
                                            The other, pressing on the Panel to the Chassey and the lines disappears 99.99%
