My PCB is similar to that: viewtopic.php?f=10&p=241918 (similar but nat same)

I use the 200 ohms range of multimeter and somewhere 200k range... Measuring results:

coil A : 109 ohm

coil B : 72.7 k

between 5vin-5vout : 49.2k

ground-5vin : 10.6k

ground-5vout : 39.2k

Those measurements appear to be OK. Can you now measure the voltages?

[selmansanli]

voltage measure:

5V in and 5Vout = 5.1V (look like 5v e-fuse is ok)

coil A =1v and other side of coil A 0.44v

coil B = 2.87v and other side of coil B 1.5v

resistance up side 1R5 =2.85v (two sides 2.85v)

resistance down side 1R5= ( one side 1v other side 0.8v)

CAPASITOR GROUP ONE SIDE 5V OTHER SIDE ZERO VOLT (YOU CAN SEE PICTURE)

VOLTAGES

It appears that the voltages are OK. Just be sure, here are the actual test points:

ISTM that the problem could be firmware related.

ISTM that the problem could be firmware related.

have you an idea to solve firmware problem?
what is the mean of ISTM?

[fzabkar]

Sorry, I have no solution for firmware problems in SSDs.

ISTM -> it seems to me

[selmansanli]

If i have same ssd, can i copy the firmware and flash the bricked ssd? Do you know a way to flash firmware for bricked ssd?

[fzabkar]

The "firmware" consists of several modules. AIUI, a common failure mode is corruption of the Flash Translation Layer. That's not something that a firmware download can repair. You could try waiting for an hour or so to see if the drive fixes itself and then comes ready, but I don't hold out much hope for you.
