[Xperia Play Q&A, Help & Troubleshooting] robis97:
Current situation

So I experimented a little more, and I have come to a point where I can actually give some logs.

The SIM Card fix​

The mobile network is working( i can detect cellular networks). The only problem is that there are

3 golden pins missing

. Resoldering them probably would fix undetected SIM CARD. I currently don't have appropriate soldering iron to do it, so it will take me some time, to actually try this solution.

The WIFI problem​

As to the WIFI, I can't find any solution yet.

I installed the stock firmware R800i_4.0.2.A.0.69_World.ftf and DooMKerneL v14 with WIFI modules(also tried with stock kernel, but they give the same error)

So now, if I turn on LogCat and look at the reports, i can see these lines:

so these are some of the errors i captured, and which seemed important to me :

Does anyone here knows what all this means? I haven't found any explanation on internet yet.
