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? |

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)

It appears that the voltages are OK. Just be sure, here are the actual test points: Attachment: V4.jpg [ 91.39 KiB | Viewed 14741 times ] Attachment: V3_V2.jpg [ 111.05 KiB | Viewed 14741 times ] Attachment: V1.jpg [ 215.53 KiB | Viewed 14741 times ] MP2109DQ, Monolithic Power, Dual 1.2MHz, 800mA, Synchronous Step-Down Converter, 2.5V - 6V in, marking B7xx: https://www.monolithicpower.com/pub/med ... 9_r1.4.pdf MP28258DD, Monolithic Power, 3A, 4.2V - 20V Input, Synchronous Step-down Converter, marking AAA, QFN12: https://www.monolithicpower.com/pub/med ... _r1.14.pdf |

ISTM that the problem could be firmware related.

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.
