Hardware problem?

[SilvanoP]

Hello,
i have huge problem with my experia t, it was affected by occasional reboot and battery drain. After i replaced the battery it seems to be better until 4 days ago, when it began to rebooting every 5/10 minute and 3 day ago it just died.
Now if i try to start it, it gust blink with red led twice.
I tried
recharging it for 12 hours
soft/hard reset
reflashing with newer and older ttf

i wanted to try also flash kernel but i need root permission and i don't know is it's possible to root from fast/flashmode

sending 'boot' (10215 KB)...
FAILED (remote: The Device must be rooted first)
finished. total time: 0.015s

If you have any idea i will really appreciate

This will fix the problem with rebooting : http://forum.xda-developers.com/showthread.php?t=2449242 . As for phone not booting it may be a brick or something, you can try flashing a whole firmware(that should rely do it). This may be helpful too (in a case of a brick) : http://forum.xda-developers.com/showthread.php?t=1849170

// ok so what has happened is your phone is fully drained. What you have to do is take it apart again, unplug the battery. Wait 10 secs...now hold the power button and plug your charger(keep holding). This time you'll see SONY logo, as soon as you see that, plug battery in(keep holding). If you did the process correctly you should see battery charging screen(release power button). Charge for about 5-10 mins and VOILA your phone is back!

Good Luck!

Thank you for your advice, it's worked for me without holding power button and put the battery cable as soon as phone vibrate on SONY logo, but after a night of charging (the battery logo was almost full) i tried to power on and after 30 sec of just black (but back lighted) screen it switch off and now it again red(empty) battery.

Update; now i reflashed it with oldest stock rom and it seems to see the battery properly (it's always green and almost full) but when i try to power on, it goes from sony logo to battery charging logo=(

Up2:Managed to make my way to the "flames" logo with stock kernel, but still the same, after 30-40 sec of "flames" it goes to charging logo screen
