Samsung "MU" series (UN, UA, UExxMUxxxx) fault dump IC1604 25Q40...

[lotas]

Interesting...
All voltages are present, but the indicator does not light up.
However, when I try to flash the SPI with a working firmware from a similar model, the indicator lights up, but there is no startup...

Then check what status register is set, maybe it has crashed (it should be 0x88, 0x42).

Dear lotas ,
After installation in the TV, the status changed to 0x46.

[lotas]

There should be only (S3, S7, S9, S14).
Try to record your native dump again via NeoProgrammer_2.2.0.10.

In the program:
1. Click "Detect Chip" and select W25Q40CL and "Select IC".
2. Click "Unprotect".
3. Click "Clear IC" and "Yes".
4. Click "Open File" and select your corrected dump.
5. Press "Program IC" and "Yes".
6. Click "Verify IC".
7. Press the down arrow to the right of "Unprotect" and select "SREG Edit", put a check mark on SRP0, BP1, CMP, QE (S3, S7, S9, S14) and press "Write" and "Yes"
7. Close the program. Ready.

Dear lotas ,
I already have some default parameter set. That's why I can't set the register code 0x42.

[yureyko]

Maybe I have a problem with the SPI chip or the CH314A programmer. Mine is not modified. Do I necessarily need to modify it?

[lotas]

Try to remove protection first, i.e. remove all checkboxes and press "Write", then erase and write dump again, then set the status register again...

[yureyko]

The same result, it immediately enables that parameter.

[lotas]

Try this dump.
And is your CH341A black or green?

[yureyko]

The same behavior in three programs (SiberiaProg, Colibri, NeoProgrammer).

[yureyko]

Try this dump.
And is your CH341A black or green?

I tried your firmware, but I have the same problem. I have a black CH341A.

When I try your other firmware for different TV models, I still have the same problem. It's probably an issue with the programmer or the SPI chip.

And in the settings it is set as green.

[yureyko]

I was experimenting with everything back then... Now all the settings are correct.

[lotas]

Do you use it through a clamp or do you unsolder the flash and use an adapter on the programmer?
Try another flash...

[yureyko]

I desolder the SPI chip and clamp it with a clip. I haven't had issues with this before.

Will the Winbond W25Q40BVSNIG chip work?

[lotas]

I haven't tried it, try replacing it with this one.

[Diah]

W25Q40BVSNIG have difrent clock signal at I2C will not take effect as the CL

Don't make me laugh, where did spi flash get the I²C Protocol from, it's not eeprom.

then start to laugh lotas, script written as befehl which SoC do it as I2C act via eMMC / NAND firmware , when position of script address at SPI or eEPROM different the SoC will take order but it cant deliver it to Main Firmware.. this called Step BY Step start..

[yureyko]

My dear lotas,

I ordered the Winbond W25Q40BVSNIG and W25Q40CLNIG chips to check if there will be any difference.
