    I bought two damaged players on eBay and I'm trying to fix them (display is showing "LOAD").

    I expected that main PCB should be BD-P1620, however there is a BD-P3600 (on NAND is label BD-P1620A and no SATA port installed).

    Is this OK or I bought fake hardware.

    Which firmware version I should use - for DB-P3600 or DB-P1620 or DB-P1620A ?

    ************ Edit: several hours later ***********

    I connected serial console, boot loader is running, but I don't have any idea how to extract firmware from RUF file and run it ?

    Sorry I can offer no solution to your problem - although I'm having exactly the same problem with a BD-P1620 bought from ebay.

    As soon as I upgraded the firmware the word LOAD appears, and I either get a distorted boot screen, or nothing at all.

    On further inspection I've also found the main PCB is marked BD-P3600 and not BD-P1620 - so assume I've unknowingly bricked the player by installing the wrong firmware version. This might of been a good thing to mention on the ebay item description grrrr :mad:

    Anyway back to the point - how exactly are you connecting to the player? I've used a serial console to connect & upgrade/downgrade nokia firewalls before - but that was quite a few years ago now.

    .............my next plan is to replace the PCB

    >PCB is marked BD-P3600 and not BD-P1620 - so assume I've unknowingly bricked the player by installing the wrong firmware version.
    I think there are two versions of BD-P1620 player
    BD-P1620 on PCB BD-P1620
    BD-P1620A on PCB BD-3600 (with limited by firmware functionality)

    >how exactly are you connecting to the player?
    There is a OPUCN1 connector (15 Pins)
    Code:
    OPUCN1 pinouts:
    |1 3 5.....13  15|
     \2 ..........14/
    
    1 TX
    3 RX
    13 3.3V
    15 GND
    
    COM : 115200,n,8,1 and you have to use TTL -> RS232 converter
    >.............my next plan is to replace the PCB
    PCB perhaps is fine, you need to download right vmlinux.gz kernel.

    My player has one bad row in flash - this is the reason why CFE boot loader can't check firmware signature.

    If you will able to connect console, pls send to me flash_nand dump. I will try to merge both images to obtain valid vmlinux-secure-signed.gz file:

    Code:
    configure TFTP server and ENABLE write (like tftpd32.exer)
    CFE>ifconfig ... <- set IP, mask - 'help ipconfig'
    CFE>save 192.168.x.y:flush_dump 0x1fc00000 0x4000000

    I use kernell from Momitsu player (same Broadcom BCM97xxx procesor) - usefully only for boot, this image can't play BR/CD

    There are tools to manipulate nand memory: /bin/nanddump and /bin/nandwrite.
    I'm still looking for volunteer who can connect rs232 console to do kernel dump.
    This can be first step to create BR region free image.

    I also have one of these players and am keen to fix it,
    what is a OPUCN1 does it have another name, how do you buy the relevant connector to rs232 port

    The name are: OPUCN1 - board BD-P3600 or UCON1 for board BD-P1600
    You need to use standard RS-232 -> TTL converter (MAX 232)

    Do you have a splash screen on TV (bluish background)
    if not -> bootloader doesn't start so you have hardware problem or bootlader is demaged - I don't have idea how to fix it

    if yes -> check converter
    disconnect pins 1 and 3 and connect them together, in terminal window echo should works (you will see what you type)

    @PIORUN:

    My Samsung BD-P1600 blu-ray player only displays "LOAD" after a failed firmware update. Nothing else works.

    I'm also trying to find a solution.

    From your description, does my player have a damaged kernel or CFE bootloader?...Is this stored in the Broadcom chip? or in the NAND?

    Do you know how to program the NAND with a damaged bootloader?

    I think we can obtain the correct firmware file for our players directly from the RUF file...

    These Samsung blu-ray players use a Broadcom chipset. The Broadcom processor uses MIPS processor code.

    The RUF firmware file from Samsung website is just a compiled version of MIPS code (MIPS32). I don't think it's encrypted.

    Since the RUF file is actually a MIPS32 memory dump file, you can use a MIPS disassembler to extract the RAW firmware. I think there are free MIPS "disassembler" programs on the internet, but I have not extracted the firmware yet.

    I can build an RS232-TTL converter to connect to the serial console, but I need help:

    1) What serial program did you use?
    2) What COMMANDS you use? I don't know how to interact with the CFE using serial console?
    3) What commands can we use to read/write the firmware?

    I look forward to your reply.

    @ PIORUN:

    Thanks for sharing the recovery flash for your player.

    I have a few more questions:

    1) My player shows only LOAD... Do you know what partition is corrupt? kernel or rootfs?

    2) Is partition "mtd10" a duplicate copy of all other partitions combined, just stored in a different offset in the NAND?

    Can I extract each partition separately and then compare (for example) partition "mtd1" (kernel) with partition "mtd10" (all) offset 0x00180000 to 0x00680000?

    Will this show my problem? then I can check "mtd2" the same way? If yes, then can I extract the good version from "mtd10" and replace my damaged one in "mtd1" ? Unless"mtd10" is damaged also?

    3) Your player is BD-P1620 or BD-P1620A but mine is BD-P1600.. Can I use your kernel and rootfs or will there be problem?

    4) What are the commands to extract/dump each partition from the NAND? Is it "nanddump"? I assume the command will store the dump on the NFS, and then I would need to transfer the file to my computer?

    5) Is the nandwrite command part of the rootfs_XXXX.tgz file?

    Sorry for all the questions. Thanks for your help.

    You have to send log from console ..

    >2) Is partition "mtd10" a duplicate copy of all other partitions combined, just stored in a different offset in the NAND?
    this is not a COPY - raw NAND

    >Can I extract each partition separately and then compare (for example) partition "mtd1" (kernel) with partition "mtd10" (all) offset 0x00180000 to 0x00680000?
    I hope (I didn't test it)

    >3) Your player is BD-P1620 or BD-P1620A but mine is BD-P1600.. Can I use your kernel and rootfs or will there be problem?
    AFAIK BD-1600 has the same MB/CPU like BD-P1620

    >4) What are the commands to extract/dump each partition from the NAND? Is it "nanddump"? I assume the command will store the dump on the NFS, and then I would need to transfer the file to my computer?
    yes

    >5) Is the nandwrite command part of the rootfs_XXXX.tgz file?
    this is unsquashed rootfs (mtd2)

    Anytime I execute:

    boot -elf -z -tftp 192.168.10.77:kernel.gz

    It tells me:

    Loader:elf Filesys:tftp Dev:(null) File:192.168.10.77:kernel.gz Options:(null)
    Loading: Failed.
    Could not load kernel.gz: File not found
    *** command status = -18


    Any help would be appreciated.

    Thanks!

    Unfortunately I don't have kernel/rootfs_dump for BD-P1600, however you could try BD-P1620 – the same mother board …
    Code:
    [URL="http://rapidshare.com/files/429938601/RecoveryFlash_SamsungBDP1620_MainBoard1600.zip"][COLOR=#000000]http://rapidshare.com/files/42993860...nBoard1600.zip[/COLOR][/URL]
    

    >boot -elf -z -tftp 192.168.10.77:kernel.gz
    192.168.10.77 - sever wih TFTPD / OpenTFTPD ...
    kernel.gz - this file must be in TFTD /root_share_dir

    the player is a BD-P1600 w/3600 board.

    1.)You have serial connection between Comp and BDP?

    2.)You have Ethernet connection between Comp and BDP?

    From what terminal do you use the "nandwrite" command?

    Thanks

    You have to load kernel from net instead of /dev/romblock2, check readme ....boot -elf -z -tftp server_ip:kernel.gz

    So close!

    Turns out an issue with my Windows7 firewall, when I switched to XP computer, now can get to point where it is looking for Root-NFS, but errors out.

    What do you use for NFS server?

    The TFTP file transfer continuously errors out when trying to boot the kernel.gz, error is that file size is too big, that memmory is full on BD-P1600. I tested with 0kb file named kernel.gz, was able to transfer file. Any suggestions? clear flash?

    Thanks in advance

    Kernell is running fine, you have a problem with NFS server.
    I use Linux with nfsd as a server.

    should be /var/lib

    Could you mount this exported root on other Unix/Linux system?
    # showmount -e 192.168.10.77
