[Nexus 6P Q&A, Help & Troubleshooting] k0l0bun:
Recently my Nexus 6P crashed.

It was Nexus 6P boot-loop issue.

I’ve tried to fix this issue by heating of the Qualcomm processor in the hope that BGA balls remain electric contact and phone will be fixed.

That was my failure.

Due to aspects of an assembly, such a method is useless.

Moreover, after heating, I get more BGA disconnects, so my phone died completely.

Now I’m trying to recover my data from the phone.

I de-solder eMMC from my phone and opened it.

And this is what I found it inside:

As it can be seen, my eMMC contains >40 volumes.

My data seems to be “Volume 39 (userdata)”.

But I can’t open this volume because of unknown type of file system.

Does anyone know how to read this volume?
