So this is my friends phone, he received a notification that there was a newer android version available and if he wanted to update. I had advised him not to update this this way (OTA?), but he couldn't resist.
It had stock 2.3.3, and it was unlocked following Alejandrissimo's method (
Now it does not boot up, nothing happens if you press the on/off button

What do you advise me to do?
If possible I would like to put S.E.Tweaked rom v 0.7 and Inteks kernel v15 inside
So far I found this, should I follow first or second guide? Any other ideas?

1 Fota unbrick
by testadeferro

Here is something to repair your bootloader after a FOTA update and phone iIn the package you have flash tool and the files you need.
Just unzip to a folder and then use flash tools.
The needed files are in the right folders.
After this you should have your phone fully back for a fresh rom install.
Use wotanserver to flash a full custom rom of your choice.

There´s not much to explain, this .sin and ftf files repair the damage bootloader and the trim area.
If you ´re unable to start phone after a fota update with unlocked bootloader.
Just plug the phone and connect it pressing back button in your xperia neo and press flash on the flashtool. And voila you have you phone live again.

2 [How-to] Repair Damaged Bootloader + Trim Area [Red Led][Unknown Device]
by Alejandrissimo

Sometimes we can brick our devices by a bad unlock, flashing process, or simply bad luck.
The phone doesn't turn on and there is a Red Led Of Death when pressing power button. Even with a GREEN led when we plug the phone with back key pressed the computer detect the phone as "unknown device" so there is no chance to get fixed by Flashtool or SEUS/PC Companion.
Well this problem normally means that the bootloader is broken or damaged. So, in order to fix it we need to write a new SEMCboot and after this we were able to flash a full and fresh firmware with flashtool and unbrick our Xperia.
This process like unlocking process requires SETool dongle/box and a paperclip to make a testpoint to put the phone in flash mode and be able to write the SEMCBoot.
I can help to anyone with a bricked Xperia Arc/Play/Neo/Pro just make send me a PM.

Ok Alejandrissimo pm'd me this:
Thanx mate!

[Tutorial] Fix FOTA bricked (unlocked bootloader) Phones

This will fix your unlocked Phones which got bricked through OTA update and are dead now!
Please download this package:

Let it extract to a destination of your choice.
After that run Flashtool.exe.

Now hit the button FLASH and select the package which is included.
Follow the steps and connect your phone in flashmode. This is the same mode Pc Companion and SEUS uses to flash your phone to newer firmare (Indicated by green LED), if you got BLUE LED you are in the wrong mode!
Flashtool will now detect your phone and start the repair.
After all is done your phone should be up and running again.

PLEASE DO NOT ACCEPT ANY OTA'S ! If you receive a OTA message just decline, if you accept it you will end with a brick AGAIN! So please do NOT accept them until SonyEricsson provides a OTA solution for unlocked Bootloaders!

Best Regards
Team FreeXperia
