I have had my fair share of problems getting out of all kinds of tricky situations. :fingers-crossed: I thought it would be nice to share my knowledge and experience with the good folks on XDA
Using this guide you can get out of the following problems:
- Bootloop: Sony logo -> Xperia logo and/or bootanim followed by a reboot
- Bootstall: Sony logo appears, nothing else happens
- Soft-brick: Phone vibrates when you try to turn it on, nothing else happens, not even the screen turns on! (Formerly named Refuseboot)
A bootloop occurs when your rom has missing or corrupted files or otherwise an incomplete system partition.
A bootstall is caused by a heavily corrupted system partition to the extent you could say it is nolonger there... or an android service that fails to start during init.
A soft-brick can be caused by either a corrupted TA partition or by relocking your phone while you have a custom kernel image still on it (big oops! and yes: I have been in that situation myself :silly: )
Xperia Z: Testing functionality before we start...
Bootloop/bootstall: Try to reboot your phone by holding down the
POWER and the
VOL-UP buttons
at the same time for a few seconds. If it reboots, you can be happy! :highfive:
Soft-brick: If you can feel your phone vibrate when trying to power it on, even when your screen does not turn on, you can also be happy! :fingers-crossed:
The above functionality
SHOULD also work on the Z1 and the ZU.
Xperia ZL: Testing functionality before we start...
The ZL has a small reset switch behind the lid where your SIM card goes. You need a pen or something similar to operate it and it should be labeled 'reset' or 'off' inside the case. To reset your phone, you will need to use this switch. The selection between Fastboot (Vol-up) or Flashmode (vol-down) however is the same.

Now that we know we can re-/boot your phone, you have a way out of this problematic situation! :victory:
