Hard Brick warning - Read Before Bootloader unlock




This post is intended to point your attention to the simple fact that there's a hardware imposed danger to hard brick your Xperia X8 and W8, applies to E15i/a and E16i/a, at the attempt to unlock the boot loader!

The phones affected by the problem are units being manufactured at, and after, 11W29!

To check if your device is affected by the problem follow this simple steps:
  • Turn off the phone and open it up
  • Take out the battery
  • Look at the sticker below
If the date code on the sticker reads 11W29, or any later date (11W30, 11W31, 11W32, 11W33, ...), DO NOT attempt to unlock the boot loader.

These phones ship with a revamped chipset configuration having the security hole the boot loader unlock uses effectively closed. This means that upon unlocking the boot loader your phone will end up as a hard brick - and you will have NO means to revive the phone yourselves. You either have to send it off to Sony Ericsson for repair (recommended solution) or find a phone repair shop being able to resurrect shot devices!

The symptom you will experience when unlocking the boot loader on an affected device is like this:
The boot loader unlock will most likely go through fine
At restart the phone will show NO signs of life anymore.
NO LED, NO LCD output, NO vibration.

This is the point where you can not do anything anymore yourself to resurrect the device.

You have been warned, DO NOT TRY to unlock the boot loader on phones manufactured PAST 11W29!
