Though keep this in mind: If you SIM unlocked your phone chances are it could revert back to the original SIM lock upon boot loader unlocking!
My friend has no plan of sim umlocking the phone. All he wants is a new kernel

The important line is this one here:
Quote:
If the simlock certificate specified is NOT RECOGNIZED SIMLOCK CERTIFICATE, you can't unlock the bootloader of your phone. If you try, radio capability of your phone will be disabled
Take the added comment...
Quote:
(this has been reported to be untrue by a number of people who claim to have unlocked bootloader successfully with msm7227_semc.cmd).
...with great caution! Better NOT to proceed in this case.

noo, [Faceplant]
that line saying simlock certificate is what you need, if it has something like NOT RECOGNIZED SIMLOCK CERTIFICATE

Nice to be back.

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:
  1. Turn off the phone and open it up
  2. Take out the battery
  3. 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!


Update (2012/02/23):

To clear up the "no means to resurrect the phone yourself": This is true unless you are a experienced electronics technician. If you own a JTAG box (RIFF Box, Medusa Box) you may attempt to resurrect the device through JTAG. It may also be possible to resurrect the device through UART flash by using a test pin connection. Google is your friend here to dig up the required informations.

As posted by baiclark: There's an option to unlock the boot loader on 11W29+ devices, though this involves some Software (setool2) where you need to buy credits to perform the unlock. This is an untested procedure. If you decide to jump the gun please report your experience.

mine was 11W17 is it safe for unlocking BL?

Now let is do some math class...

12W0x <-- NOT good!
11W5x <-- NOT good!
11W4x <-- NOT good!
11W3x <-- NOT good!
11W32 <-- NOT good!
11W31 <-- NOT good!
11W30 <-- NOT good!
11W29 <-- NOT good!
11W17
11W02

Now here comes the question ...

Is 17, or 2, lower or higher than 29?

If it is LOWER you can try
If it is HIGHER you DO NOT try

Now take your calculators and solve that little problem. You can also put it this way ...

If having 29 apples is a bad thing and you only have 17 or 2 apples, would it be good you have less than 29 or would it be bad?
