Hi there!
I received a z310i, it doesn't turn on.

I've tried to flash it with SeTool, however it returns this error:

llbug: write timeout [Overlapped I/O operation is in progress]
packet timed out (01)
subblock 017 NAK, [44140000/00010000]

I've checked the battery, it's new and okay. I've tried different USB ports on my PC, no luck.

The rest file is created via ssw2rest and using .mbn file.

What else can I try here?

I've also attached a log from SeTool.

Hello and welcome to our forums!

Afaik you just gotta full flash it (.mbn, .fbn, cda) then generate rest for future just in case, I read it's CID 52 so no problem you could use FAR manager with plugins as well but if you care for file system you could try to flash just .mbn and try to turn it on, if it's just soft brick, else I'd dismantle the phone and look for signs of any water ingress or other damage, if you got the access to ultrasonic bath cleaner it's not impossible it could help in that case, otherwise trying to heat the main IC on the board is the other step, else idk, btw, do you know some history of that piece?

This method doesn't work, unfortunately, it was the first thing I tried.

If I try to flash it, the error in SeTool is next:

GDFS startup failed,error is 04 [1D]
GDFS startup failed, this is fatal

I'm not sure what happened to this phone before, though.
