Sony Xperia L (C2105) charging problem

[Wolldamn]

I will tell the whole history just in case, it might be relevant.

It started with battery problems, it was charging at a very slow rate (4-5 hours)  and it was lasting 1 hour top. The camera was the cuplrit, it wasn't working at all and by disabling the camera app the phone worked fine for a week.

Suddenly stopped charging now.

1. When  the phone is on it doesn't recognize the charger not even the computer, no bottom led. The computer doesn't recognize the phone either.
2. When the phone is off, if i connect the charger, then the bottom led turns red for a second, SONY logo appears, battery appears for another seconds and reboots... infinitely.
3. I thought that the USB connector was the problem but i can connect it to my laptop in fastboot mode and flashmode, the phone is recognized in both modes, i even "repaired" the phone with Sony PC Companion and i'm having the same problems like before: no camera and no charging.

I don't think it is a firmware problem, i've re-flashed the stock firmware from XPERIA Firmware and no success.

Any ideas? Thanks in advance!

You should contact your local Xperia Care

You could boot on safe mode and check again

Tried "Safe Mode", nothing happens

Sorry to hear that, you must contact your local Xperia Care

thanks for replying so fast but i was hoping for some ideas, i have no intention to contact Sony.

The phone is 2 years old out of warranty, if i can't repair it on my own then i will go buy another one. It's not worth the effort to contact some specialized departement to tell me that they can repair it for 100€ when i can buy a better new one for 150€.

I think that i've asked for help in the wrong place

If the micro USB port its damaged, then there's not much you can do as you will have to replace the motherboard, and that will cost you quite a bit, almost the same as a new phone.

My Xperia L just started developing the same charging problem as described above. I really wait for a solution to surface from the forum other than contacting local Sony center.
