Hi

Recently I went on to tackle this Kingston 9904234-383.A00LF USB drive.
The memory ICs are Toshiba TC58NV64D1DT600 while the controller is unbranded with the following markings


Made sure none pins on the ICs were shorted/loose, cleaned off any gunk which wanted to come off with IPA. Then I soldered the 0.02mm copper wires from USB A male plug to the corresponding VIAs, made sure none got shorted together (especially D+/- to +5V), and plugged it in.
Sadly, the drive was detected with error 43 in devmgmt.

Looking closer I think the GND wire was shorting some line going into two VIAs (the copper wire isn't enamel coated). Sadly, when I was correcting that mistake pretty much all of the wires broke off, which were pain in the butt to solder on.

Now, my question is, could anybody mark which capacitor should I inject 5V into? The VIA of Vcc goes under the controller IC and it seems like it just stays underneath it.

I managed to solder the wires back on. Double checked for shorts and plugged it in.
Sadly, nothing happens. Hitting the scan for new hardware button in devmgmt doesn't result in the drive being detected. The controller IC isn't also heating up...

Turns out it was the GND pad not making a good contact.
With that out of the way, windows still reports a error 43 on this device.

Any ideas what might be the cause?
