Hello guys, i had an Xperia U with unblocked Bootloader and every time I had a single bootloop, (Only Sony logo appeared) i just pulled my battery off and installed Stock Ftf thorough flash tool. Now I bought an Xperia S and I am thinking of installing a ROM.... What shall I do in case a boot loop appears, since the battery is not removable? I really need an answer guys.
Thanks in advance.

Edit: Answer was given by Envious_Data

one buzz ~ force off
3 buzz ~ hard reset (like pulling your battery)

hmmm it depends on what your looking to do

if you want to keep your bootloader locked folow these steps

root your device
install cwm for locked bootloder
make or downloadflashable zip of stock rom
flash if bootloop

for unlocked bootloader
Root
install cwm (one for lbl works on ubl for obvious reasons)

install a custom kernel
(almost all for xperia s custom kernels have recoverys commonly cwm and some with twrp)
make or download a stock rom

i dont know what you do with your phone so this is a mostly failsafe fix

So, in case i fail doing sth i must have a Stock ROM zip in my phone's memory, and when my phone starts boot(loop)ing, i should enter cwm and flash the Zip.Thanks bro!
And a last question, what happens in case someone doesn't have a Zip ans his phone keeps boot looping?

You can switch off using by pressing Volume up and power key while the device is on. This is similar to removing battery of the phone.

yes holding volume up and power will force off

one buzz ~ force off
3 buzz ~ hard reset (like pulling your battery)

you can power off during boot from your PC but id recommend forcing off instead, it seems data gets corrupted more easy when its requested to turn off
