    You need to download emmys from BOOT1-BOOT2 and USER chapter3 partitions. If you want to keep full functionality. You need to read from EMMC BOOT1 and BOOT2 , as well as section 3 factory_setting . Otherwise, full functionality cannot be restored.

    Hi, I have the same problem with the same motherboard. Only BOOT1 and BOOT2 are readable. The eMMC (Toshiba) is totally fried.
    Anyone have a dump?

    Can you please tell me how did you partition the USER eMMC area?
    I have RT809H Programmer and I don't find this option.
    Is there another software that I can use?
    And do I need to copy and paste all the partitions to insert the working keys or only partition 3?
    Many thanks in advance.

Topic summary

✨ The discussion focuses on recovering and dumping the eMMC memory of a Philips 49PUS7909/12 TV with main board frame 715RLPCB0000000401 and LC490EQE LCD panel, using an RT809H programmer. Key challenges include reading the full eMMC content, especially the USER partition, which is often damaged or unreadable, while BOOT1 and BOOT2 partitions are typically accessible. Full functionality restoration requires dumping BOOT1, BOOT2, and the factory_setting partition (partition 3). There is also interest in extracting keys from the CPU to recover the TV when the eMMC is dead or damaged. Some users report fried Toshiba eMMC chips and inquire about transplanting both eMMC and CPU from donor boards. Questions arise about RT809H connection pins on the SPI main board and software options for partitioning and dumping eMMC data. SDM protection and reset pin locations are also mentioned as obstacles. The discussion includes requests for dumps and technical advice on handling the eMMC and CPU for repair and key recovery.

FAQ

TL;DR: For Philips 49PUS7909/12 eMMC repair, back up 3 partitions (BOOT1, BOOT2, factory_setting). "If these sections cannot be read, full functionality cannot be restored." Use RT809H or raw reads to preserve keys. [Elektroda, sergiy141, post #20463496]

Why it matters: This FAQ helps bench techs and TV repairers decide how to dump, clone, or transplant parts to recover keys and full functionality.

Quick Facts

What dumps do I need to revive a Philips 49PUS7909/12 with a dead eMMC?

Back up BOOT1, BOOT2, and the USER p3 partition named factory_setting. These hold essential data and keys. Factory_setting sits at offset 0x0006000000, size 0x0004000000. Without these sections, you cannot restore full functionality on a new eMMC. Save each region as a separate file for safety. [Elektroda, sergiy141, post #20463496]

Where are the TV’s keys stored — CPU or eMMC?

They reside in the eMMC, specifically in the factory_setting partition. The CPU is not the source for recovering those keys. As one expert put it: "Factory_Settings Here are the keys." Focus your read on that user-area partition. [Elektroda, sergiy141, post #20460181]

Can I use a donor dump from another 49PUS7909/12 to fix mine?

A donor dump will not deliver full functionality. Keys and unique data tie to your original device. "With someone else's dump, the functionality will not be complete." If your original factory_setting is unreadable, expect limitations even if it boots. [Elektroda, sergiy141, post #20463496]

My RT809H only shows BOOT1/BOOT2 and MBR. Is my USER area damaged?

Yes, that symptom points to a damaged user area. RT809H will often list only BOOT1/BOOT2 and MPBR/MBR in such cases. Try alternate connections, ISP rework, or chip-off reading. If USER p3 remains unreadable, full functionality cannot be restored. [Elektroda, somalorg, post #20463716]

How do I dump BOOT1, BOOT2, and factory_setting (p3) with RT809H?

Use this quick procedure:
  1. Read and save BOOT1 and BOOT2 via the RT809H eMMC menu.
  2. Perform a raw read at offset 0x0006000000 with length 0x0004000000 to get factory_setting.
  3. Verify file sizes and keep multiple copies before proceeding. These three regions underpin full functionality. [Elektroda, sergiy141, post #20463496]

What partition offsets matter most on this board?

The shared map lists 13 partitions (p0–p12). Key ones: p3 factory_setting at 0x0006000000 (size 0x0004000000), p5 boot at 0x000E000000 (size 0x0000C00000), p7 system at 0x000F000000 (size 0x0032000000). Use these as targets for raw reads/writes when cloning or validating. [Elektroda, sergiy141, post #20463496]

Should I transplant both CPU and eMMC from a donor board?

Transplant both only if your original USER p3 cannot be read at all. Full functionality depends on content in BOOT1, BOOT2, and factory_setting. If those sections are irretrievable, keeping a matched CPU+eMMC pair can preserve operation. Otherwise, a new eMMC with original dumps is preferable. [Elektroda, sergiy141, post #20463496]

How do I re-partition or recreate the USER area on a new eMMC?

You don’t need a partitioning UI if you program raw regions by offset. Write your saved BOOT1, BOOT2, and factory_setting (offset 0x0006000000, size 0x0004000000). Then program other partitions as needed using the same map. If factory_setting is missing, full functionality cannot be restored. [Elektroda, sergiy141, post #20463496]

Does anyone share full eMMC dumps for this model?

In the thread, dump sharing proceeded by direct contact. The guidance given was: "Enter your e-mail address." If you seek a dump, post contact details as requested and follow up with the provider. [Elektroda, sergiy141, post #21109493]

Which mainboard variant and eMMC chips are common on 49PUS7909/12?

Reports reference the QV14.1E mainboard, LA:715RLPCB0000000401, with a single LVDS. eMMC ICs seen include Toshiba THGBMAG5A1JBAIR and Hynix variants. Verify your exact board and memory before flashing or transplanting parts. [Elektroda, sergiy141, post #20404860]

Which LCD panel is mentioned alongside this mainboard?

The LC490EQE panel is referenced with the Philips 49PUS7909/12 and frame LA:715RLPCB0000000401. Confirm panel compatibility if swapping boards, as LVDS routing and EDID can vary by panel. [Elektroda, somalorg, post #20401976]

Do I need SDM protection reset pins to recover keys?

No. SDM reset is not required for key recovery. The keys you need are inside eMMC factory_setting. Focus on reading BOOT1, BOOT2, and USER p3. If those sections are unreadable, full functionality cannot be restored anyway. [Elektroda, sergiy141, post #20463496]
