Sony KDL 55W-955B Sony EMMC dump search :)

[Morosan Dimitrie]

Hello guys, can someone help me with an eMMC dump for a Sony KDL55W-955B TV, I tried to read the original memory with the RT809H but it shows me that it only has 1888MB even though it should have around 3.8GB. On a new memory it shows me 3776MB. From what I found on the Sony page, the following models could also be compatible:

KDL-65W955B, KDL-55W955B, KDL-60W855B, KDL-50W805B, KDL-42W705B, KDL-32W705B, KDL-48W605B, KDL-40W605B, KDL-60W605B, KDL-55W805B, KDL-42W805B, KDL-48W585B, KDL-32W706B, KDL-42W706B, KDL-42W815B, KDL-42W817B, KDL-50W815B, KDL-55W815B, KDL-42W828B, KDL-42W829B, KDL-50W828B, KDL-55W828B, KDL-55W829B, KDL-50W829B, KDL-50W817B, KDL-55W817B, KDL-50W705B, KDL-50W706B, KDL-40W705C, KDL-32W705C, KDL-48W705C, KD-85X9505B, KD-65X9505B, KD-79X9005B, KD-65X9005B, KD-55X9005B, KD-70X8505B, KD-65X8505B, KD-55X8505B, KD-49X8505B

Please maybe someone has a dump from those model so I can try. If it helps to motherboard code is 1-889-347-11.

Thank you in advance!

why you suspect the emmc... sony W series are known of BGA issue at Vision Soc

Because I check the power supply and is sending power, I tried to reflow the emmc without succes same thing. I check for short circuit whole motherboard and everything ok and when I check the emmc information from it is corrupted.

I hope maybe I can find someone to help me with a copy from a working emmc to try it 😁

Someone else's firmware does not work on this chassis, you will get error "3". These boards have defective memory chips (DDR).

[lotas]

If you want, try it.
Dump was read by the UFPI programmer, rename the files to suit your programmer (RT809H).

emmc reballing is required i guess.. if also corrupted files also emmc rewrite..

Hy guys. I change the EMMC with a new one and put the dump from lotas on the new EMMC and now I have 3 red led blinks. Before was no light present no blinks, from what I search on internet I should update the firmaware? Thanks for all the help!

I wrote above that someone else's dump will not help you, you will get error 3 (on this chassis), and that's how it happened. In this chassis, dump is encrypted and linked to the processor ID...

And there is no chance of fixing some how this error ?

[lotas]

Look for a donor (motherboard).

[Davi.p]

there is a little chance, as i have said, that original emmc is ok, but you like others does not trust me..

You should have first figured out if there is data flowing between D0 and the other data lines between the EMMC and the main processor. It will tell you if you got a bad EMMC or bad firmware.

How can I check this ? With an osciloscope to see if exist a signal ?

Yes.

Hello guys I m back again, from what I found on Internet I see that for this model sony modify the EMMC to work on the enhanced mode which now I understand why It was showing me half of the capacity. I ordered a stencil to fix back the bga ball of the old EMMC and I will come back with an update.
