I have an Xperia Arc with PolygonKK 1.4 custom ROM.
I had a problem similar to what has been reported many times of Xperia S where the phone becomes soft brick if the battery was completely drained, and the phone was not starting or allowing me to recharge the battery. This problem was fixed by charging the battery outside the phone and then plugging it in and starting the phone.
The problem now is that neither my phone or my PC can detect that they are connected via a data cable.
- I checked the cable with another phone, it works fine, and I am using the same PC that I have always used to handle my phone (on windows and linux).
- When I try to access fastboot mode I see the blue LED but the PC detects nothing
- Flash tool does not detect any mode connected (fastboot, ADB, Flash)
- I tried cleaning the USB port with no result.
I think now that the port is damaged, but I still have a little hope that this is a software issue, is there a way to know what has happened to the phone?
