[Q] No battery charge after flashing
I got a xperia V, and the former owner told me tha it was flashed with a xperia Acro S firmware, and no longer turned on, so i tried to put it in flashmode with no success, then I tried a trick that saw over here (on a xperia sola) that was to connect usb without battery, an then put the battery as fast as possible, to my surprise this worked flawlessly, and I could flash the phone with flashtool and with Sony Update Service as well, the problem is that after flashing the phone still didn't power on, thinking it was the battery, I replaced with a new one, but still no success, The battery is not charging (according to my multimeter). May be the phone is not detecting the battery or the board is damaged? but is strange, because if that were the case I think the flashing would be impossible.
When I connect the phone to the charger one of two things happen:
1. Constant red light
2. Red light (if on a PC, I get the sound of a device connected), then red light goes off (if on a PC the device is disconnected), and then red the light comes back with a fading effect.
After some waiting the red light disappears and nothing else happens.
Any ideas on what I've been doing wrong, or what's wrong with the phone
Some more info, when the red light first appears, from lsusb the device get recognized as:
ID 0fce:d17b Sony Ericsson Mobile Communications AB
When the light disappears it doesn't get recognized at all.
