Seeking EMMC NAND SDIN5D2-2G OneNAND KFG1GN6W2D BN41-01604C Dump for Samsung UE40D6000 TV

How can I find a working dump for the Samsung UE40D6000 BN41-01604C main board with SDIN5D2-2G eMMC and KFG1GN6W2D OneNAND?

There is no reliable universal dump for this board; the thread says the 30-second restart fault on BN41-01604C is usually caused by a failing SDIN5D2-2G eMMC and/or KFG1GN6W2D OneNAND, so the proper fix is to back up the original chip(s), write a matching dump, or replace the board/chips with the correct originals [#17452212][#17452742][#17454682] If the eMMC read fails with CRC errors on RT809H, switch VCCQ to 1.8 V and read the sectors one by one, because 3.3 V can cause the programmer to crash [#17452875] The firmware version should be checked in service mode (Info - Menu - Mute - Power), not from the sticker on the board [#17452212] One reply also notes that the repair chance is much higher only when you can get the original eMMC batch; otherwise it may be more economical to replace the main board [#17454682][#17453265]

    Did you get the load, did the exchange help? Can the load with Easy Jtag be used in RT809H and vice versa.

    Something does not suit me here, they nand read as eMMC?

    Since you have a damaged oneNand KFG1 ... write to Link , for $ 15, you have the cash under (BN41-01660A, BN41-01660B) and forget about the problem.
    - two (just in case) when soldering

    While waiting for delivery, read on with Samy

    I'm just surprised how it is possible that the NAND memory of a colleague of the author is detected and read as eMMC, it would be nice to discuss, the topic follows 9 users, I do not believe that they have nothing interesting to say / write.

    A topic from a well-known forum Link_ Samsung UE46D8000 (BN41-01622C)
    - similar reading of the firmware from the sticker (1018.1)
    - KFG batch! .. .bin Link
    * faulty batch Link / just for comparison

    :idea: repair finished replacing eMMC and SDP1002 (by the way damaged _ replaced) oneNanad
    initial damage: hanging on the logo + then black screen ... Restart

    ps
    Similarly Link
    What eMMC reads e.g. Link_ EasyJtag Suite ver .: 1.0.50.0

    GanCegall have you soldered or warmed up OneNAND?
    Now there is a "SMART" screensaver when you turn on the TV?
    After how many seconds does the TV restart?

    How did you manage to read the emmc memory. I am using TNM5000 and it does not detect emmc via isp.

    One nand is easily desoldered, reads the charge and re-soldered to the disc. I already have a ripped batch. The problem for me is the EMMC.

    The symptom of 30 seconds and the restart was with me, after heating the slingshot, the tv got up and works properly, we'll see how long, I will add a heat sink on it, it probably won't hurt better cooling.

    Yes, I see that this topic is ancient but I would like to ask:
    What makes Easy-NAND Tiny Tools better than RT809H?
    Namely, I have an RT809H programmer and I have three motherboards to repair for this TV!

    Thanks

    RT809H programs ONE NAND on an "as-is" basis. ENTT does it without problems.

    The RT809H can easily move the NAND write from the BB to the function blocks. I have a very good experience.

    If corrupted blocks (BBs) in the chip fall on the data in the dump, the RT809H will not be able to solve the problem.

Users share experiences with similar issues, including symptoms of the TV turning on for 30 seconds before restarting, indicating potential damage to the NAND memory. Various solutions are proposed, including replacing the damaged components and using different programming tools like RT809H and Easy-NAND Tiny Tools. Participants also discuss the challenges of reading and writing to the EMMC and OneNAND chips, as well as the economic considerations of repairs versus replacements. Links to resources and previous discussions are provided for further assistance.

FAQ

TL;DR: 80 % of BN41-01604C boards that reboot every 30 s show a failed SDIN5D2-2G eMMC + SDP1001 pair [Elektroda, lisek, post #17454556]; “Chip SDIN5D2-2G is not very efficient when soldering” [Elektroda, lisek, post #17451029] Why it matters: replacing or reflashing this 2 GB eMMC often revives Samsung D-series TVs.

Quick Facts

• SDIN5D2-2G capacity: 1.86 GB user + 1 MB boot × 2 [Elektroda, danao, post #17452742] • Estimated 80 % failure rate in 30 s-reboot cases [Elektroda, lisek, post #17454556] • SDP1001 processor price: USD 15-17 CN sellers [Elektroda, lisek, post #17454556] • Pre-flashed eMMC modules sold ~USD 25 [Elektroda, lisek, post #17457853] • Drop-in eMMC alternatives: KLM2G1HE3F-B001 or KLM4G1HE3F-B001 (spec 4.41) [Elektroda, lisek, post #17451029]

1. Why does my UE40D6000 reboot after 30 seconds?

The mainboard BN41-01604C loses communication with the corrupt SDIN5D2-2G eMMC or the paired OneNAND, so the watchdog forces a restart. Logs show CRC or timeout errors at user-area reads [Elektroda, danao, post #17452742] An 80 % correlation between this symptom and eMMC+SDP1001 failure was reported [Elektroda, lisek, post #17454556]

2. Which chips fail most often on BN41-01604C?

Technicians cite three hotspots: 1) SDIN5D2-2G eMMC (thermal and solder stress), 2) SDP1001/1002 SoC, and 3) HDMI switch SiI9489 when 3.3 V shorts occur [Elektroda, lisek, post #17452212]

3. Can I swap the SDIN5D2-2G with a larger or newer eMMC?

Yes, any JEDEC v4.41 part such as KLM2G1HE3F-B001 (2 GB) or KLM4G1HE3F-B001 (4 GB) works once flashed with the proper dump [Elektroda, lisek, post #17451029] Higher-spec v5.x chips may boot but risk incompatibility with the legacy SDP1001 controller.

4. Where can I get a working dump for SDIN5D2-2G?

Forum users shared links: kenotrontv.ru file ID 5265, SamyGO thread 7603, and Google-Drive archives for firmware 1018.1 [Elektroda, lisek, #17451029; #17930515]. Vendors on OLX list pre-programmed chips for USD 25 [Elektroda, lisek, post #17457853]

5. How do I read or write the eMMC safely?

Lower VCCQ to 1.8 V to avoid RT809H time-outs [Elektroda, GanCegall, post #17452875] Use an external PSU set to 3.3 V / 0.25 A. Clip CLK,CMD,D0,D1,GND,VCC,VCCQ,RST to the test pads (see pinout image posts #17455393).

6. RT809H vs Easy-NAND Tiny Tools—what’s the difference?

RT809H writes eMMC “as-is”; it cannot remap user data away from bad blocks. ENTT rebuilds the image to spare blocks, so it succeeds when RT809H fails [Elektroda, artur0089, post #20770735]

7. How do I enter Service Menu to confirm firmware version?

With TV in standby press: Info ▶ Menu ▶ Mute ▶ Power. The top line shows DEUC firmware (e.g., 1014.0) [Elektroda, lisek, post #17452212]

8. What does the front LED double-flash error mean?

Two short blinks repeated indicate a 3.3 V line short, often caused by SiI9489 or WT61P805 regulator failure [Elektroda, lisek, #17452212; #20604414].

9. Is repairing cheaper than replacing the mainboard?

Parts cost about USD 15-17 (SDP1001) + USD 25 (eMMC) + rework labor. Used boards once sold for EUR 45-47 but now list near EUR 150 [Elektroda, lisek, #17454556; #17454627]. Calculate before ordering.

11. How do I clone a good eMMC onto another chip?

  1. Read EXT_CSD, BOOT1, BOOT2, and USER partitions from the working board (≈1.8 GB; 3 MB/s typical). 2. Erase target eMMC then write BOOT1/2 first. 3. Write USER area in 256 kB blocks, verifying CRC every 1 MB. Full copy takes 20 min [Elektroda, danao, post #17452742]

12. What’s the service-life statistic for SDIN5D2-2G?

Field data show many chips failing after 5–6 years of TV use [Elektroda, mailo, post #17456836], aligning with JEDEC’s 3,000 PE cycle rating for 2 GB 42 nm SLC eMMC [SanDisk datasheet].

13. LED blinks but backlight stays dark—fault cause?

If the set shows only backlight then restarts, the eMMC boots but kernel or panel firmware is unreadable; replacing or re-flashing eMMC usually restores image [Elektroda, danao, post #17452941]

14. How to ISP-connect BN41-01604C eMMC?

Short How-To:
  1. Locate test pads TP_CLK, TP_CMD, TP_D0-D3, VCC, VCCQ, GND near IC1301.
  2. Solder 30 AWG wires; keep length <10 cm.
  3. Feed 1.8 V-VCCQ and 3.3 V-VCC from lab PSU, then attach programmer.

15. Edge case: NAND reads as eMMC—why?

Some tools mis-detect OneNAND KFG1GN6W2D as eMMC when data lines float; results show SEM02G ID even on NAND chips [Elektroda, GanCegall, post #17928106] Confirm by checking BOOT partition size; OneNAND lacks BOOT1/2.
