My battery is verry low , i think that's the problem , i tried to flash the phone and i got this error . When i put my phone to charge i get the red led.. and after 5-6 minutes i get the green one , with no image no nothing on the screen ..



Dead battery. No response from the power button, no screen and no led.
Connect to charger
low battery level charging mode. This is when just the RED led is on and no screen. At this stage the battery's charge is to low to turn the phone on, but it is charging.
Kernel controlled off-line charging mode. This is when the battery has charged enough from step (3) and boots the kernel to charge the battery. The phone is off, but could be turned on using the power button. A quick press of the power button will show this battery icon. Icon will fill with charge.

The kernel also controls charging when the phone is on.
Battery is fully charged.
Unplug the phone and turn on.
Battery is dead from normal use.
Repeat stages starting at (1)

I found this but i do not understand how to do that , any video ?

I have an Xperia LT30
