Hi everyone!
Can someone help me find power schematics of this SSD TeamGroup CX2 SM2259XT2G
The SSD powering with PC3000 Shows 0A on 5V
Shorting pins Controller cannot go to ROM mode

Many thanks!

Absolutely flat lined at 0 from power on? break it down from the sata power in, if youre getting nothing something very easy is blown open.

I did measured the resistors around in resistance mode. None of them are broken. The only thing that gets slightly hot. Like 30 degrees C is the controller

Yes. Flat lined

What is the voltage across each of the coils?
If the controller heats up, then the 5V input fuse is fine. Some voltage is missing.

I think the controller is dead

Doesnt exactly fit with a 0 flat line but check the cap near pin 1.

Im sure Erkin just posted a video of a swap on one of these with a dead controller, Its not the first play Id jump on and I think his was an obvious short.

Check the crystal.

Measure the voltages at pins 1 and 5 of the SOT23-5 IC (618 + 00022). I think that may be an LDO regulator.

10 boards for US$100, or 1 for US$26. Just add NAND.

Sorry, my question was unclear. I only needed the 5.1V/3.3V readings. That IC is a 3.3V LDO regulator and is OK.

It's a long shot, but if you shake the PCB against your ear, can you hear any rattling? If so, then that could be a shattered crystal.

Nothing is rattling

You most likely have a damaged controller.

Nothing is rattling

If you don't have an oscilloscope, you could try replacing the crystal, but a controller failure seems more likely.

One other possibility is a shorted capacitor on the reset pin, but that's unlikely.

I still have some kind of problem with the SSD

So i have swapped the Donor controller
Now the SSD can enter the ROM mode, and can ID nand fine
However if not in rom mode. The SSD still only have 0.2A The LED on the left doesnt light up? I still think there is some problem with power

ROM Mode can ID Nand and controller

Not in ROM mode christmas tree 0.2A

Does SM2259 have an encryption key?

i don't believe it has

Rossmann seems to be saying that SM2259 has a key. Is he wrong? Maybe the XT version doesn't have a key.

Quote:
When a Phison E12 or Silicon Motion SM2259 controller fails, when a PMIC shorts, or when a 0.05 ohm protection resistor blows on the 3.3V rail, the data is intact on the NAND but the controller can't enumerate. Reviving the original controller is the only path that preserves the AES-256 key bound to that specific silicon (TCG Opal, BitLocker eDrive, T2, M-series). Chip-off transplant on a hardware-encrypted drive returns ciphertext.

I don't know how he expects to revive a dead controller, though.

I think mine still have something with the power.
The LED on the left doesn't turn on when i turn on the SSD. I tested the LED it is still functional

Any other things that i can test?

Do you know if that's a power or activity LED - If you have a working donor why no just swap the nand over and get the recovery completed for the client you can work on the why this one does work after.
