I have problem with my Xperia M. I have managed to flash system.sin ONLY ONE TIME. But after turning on the phone it was saying low battery like 3%, even I knew that the battery has been charged in other phone (Xperia J) and showed about 80%. So seeing this bug with battery I've decided to flash it one more time (I read that it may be some bug with kernel/rom). Anyway since that time I cannot flash the phone again....
I cannot flash any rom to it. I have tried different ones from generic to custom. Also tried different flashtool versions (0.9.8.0; 0.9.16.0; 0.9.16.1).
I have all drivers installed. Also tried different cables, different computers. And I have bootloader unlocked (if it matters).
The phone does not show any sign of life except that I can turn it on in flashmode or fastboot. Flashing with different rom's sometimes gives different errors.
This one is most common errors

- no response to power button, no vibration (no soft/hard reset available)
- can go into flashmode or fastboot
- while connecting to PC or wall charger it shows Sony logo + constant red led, nothing more (looks like stuck on it)
I've tried flashing system.img by fastboot but it says that this file is too large (something like this), I've read that it can be done only with system.img smaller than 256mb (mine are about 1GB)
