I agree with what is being said here. However I would recommend that you flash back to .434 first that these methods have worked for many times, and it is more known version for attempting this.

Just reflash the .253 with a full wipe using flashtool.. it's bit trickyto enter to flashmode during bootloop. Just make sure to press volume down key & plugin the USB cable when the screen goes off.. type *#*#7378423#*#* in dial pad once it loaded you will have bootloader unlocked:Yes
I had the exact same problem.
I had unlocked my bootloader via the official Sony way.
Installed CM10.1.
Went back to stock Sony ROM (after relocking bootloader and flashing a tft via flashtool).
Tried the official way to unlock my bootloader, and all the time had a boot loop.
Tried to unlock my bootloader via flashtool and didnt have a problem.
Back to CM10.1 for me now!
If your phone reboots mid xperia that mean there is a system error.
With doom v6 kernel that is 4.1.1 based so that might be why you are getting bootloop if you are trying to flash kernel on a up to date 4.1.2 system

Is it possible to relock a bootloader and flash a stock rom onto the phone so normal sony updates will work after trying something like Cyanogen? Just wondering for future knowledge.
I think if i'm right you can lock the bootloader with fastboot oem lock, but not sure if the flashed stock rom then takes sony updates?

Yes it is. Flash a relock ftf file and once you do that normal updates can be installed.

Thanks, having a major crisis at the moment. cm10 was buggy for me and didn't work. Now I can't get the phone to boot without errors and can't get flashtool to recognise the phone. I just want to go back to how it was now to have a phone that works.
I downloaded flashtool but the phone doesn't seem to boot half the time and when it does it's buggy. It's not seen by flashtool correctly, seems some drivers are no longer working for it.
I did download a stock rom (pre rooted) but despite flashing that the phone still seems to have cm10 on when I boot up. I'm thinking I'll just go back to stock if I can somehow manage to do it, the latest stock as the problem with my phone initially was it wouldn't complete the stock updates.

The phone now shows up as an MTP USB Device which fails to start, it no longer boots and I can't get it into recovery.
Do you have a Xperia T? Did you use this to relock the bootloader?

Once you relocked the bootloader then the cm10 custom kernel would not be able to load as it needs an unlocked bootloader.
Follow these steps.
Download and install flashtool
Download a stock ftf from the all in one thread for your phone (Dont worry about the fw version, but if you want to root it should be an early one, eg .303 or .305)
Open flashtool
Drag and drop the ftf into the open window of flashtool
Turn phone off, wait 30 seconds
Attach USB cabe to PC, then to phone. WHilst connecting to phone press and hold volume down button.
It should now work, if it doesnt copy and paste the flashtool log here
I know you have said your pc does not recognise your phone, but please try this exactly as i have said and post the log if it does not work.
Thanks that does work and I am now on. 195.should I relock bootloader to get updates or flash manually each time?

Trackid works fine with unlocked bootloader. To get bravo engine back you have to do some extra work. Heck out the thread in the Xperia S dev section to see how they got it working again.

ok finally getting around to doing relock. I can't get flashtool to see the ftf i drag in, nothing happens.
There a thread on mobile bravia engine trying to fix this problem. See thread below :-

Evening guys
Just tried to unlock my bootloader via the Sony website.
After succesfully unlocking and rebooting it keeps repeating the booting.
I see the Sony logo and the Xperia logo. Then it goes of and back on again and keeps doing the same.
I already tried to flash back the stock firmware and that works.
When I retry to unlock the bootloader the same thing happens.
The service menu says I can unlock my bootloader.
Any tips or tricks that might help me to unlock it.

It is hard to say from your explanation whether your phone is unlocked or not.

SUS doesn't work for phones with unlocked bootloaders (neither does PC Companion).
Get yourself a full ftf for your current customization & flash with the official flashtool (Emma).

Did you put your TA backup back onto the phone before relocking?

No I don't have TA backup .. I unlocked my bootloader without making TA backup
PC companion solution maybe !!
Now I'm trying to repair my phone by Sony PC companion, it's downloading the software update now.. hope that this is a good solution.. I can stop if not because it needs 2 hours and more to complete, because of my slow connection...
It should work fine after you use PC Companion.
It wont boot as your using a non Sony kernel (has recovery). If you flashed a stock, non modified kernel before you locked your boot loader it would be fine.
If for some reason PC Companion cant fix it, just unlock the bootloader again and flash a stock kernel thats not been modified and then relock your bootloader and it should work fine.

I unfortinately formated system in clockworkmod touch recovery. Afterwards phone gets stuck at sony logo when i power on the phone. Am able to boot into fastboot and flashmode using key combinations but cant enter into the clockworkmod with key combinations as i used to do before the system format. However, i unlocked my bootloader and rooted the device before i had this problem. As a result, am not able to get sony pc companion to repair my phone. I tried flashtool but then upon flashing, it asks me to enable usb debug mode and am not able to enable debud mode since the phone doesnt boot past the sony logo.
I will appreaciate it greatly if anyobe can help me get my cute phone out of this situation
On android 4.0.4
Sorry if i posted in a wrong forum.I'm new here

If you can get in fastboot mode you can allways relock your BL and repair it via PC Companion.
I have a sony xperia z c6603 , it was never unlocked from the start but it worked very fine on its original firmware, android 4.1.2. But then someone flashed a c6602 android 4.1 on it and now the IMEI is corrupted and it restarts every 9.3minutes.
It says bootloader unlock allowed: Yes which I guess means the bootloader is locked and can be unlocked, but since IMEI is corrupt, i cant request for unlock code from sony or use fastboot.
My only other option is the famous flashtool. I have three issues with flashtool.
1. I already downloaded the correct firmware and preparing to flash, so I click on the flash icon and start flash (Using Androxyde flash tool). It goes through the normal process and then an empty device selector screen comes up, with no option but to cancel. and when i cancel, it says "loader not found for this device"
2. Okay, after step 1, i am thinking "maybe i have to unlock the bootloader first" so i click on the BLU button and connect the device in flash mode, it starts and the empty device selector screen comes up again, once i cancel, it says "your device can not be officially unlocked"
3. So i did a little bit of digging around on here more and found that i have to update xflasher.jar to beta6, and so i did and flash tool started as "androxyde and bin4ry flash tool" .Only problem is when i click on the flash icon and choose flash mode, nothing comes up, i cant get into flash mode. but I can get into every other thing like fastboot mode and BLU
Please if you think you have an idea on how to solve this problem, please reply. I cant afford a new phone and I would also like to know if my phone can be repaired too, I also dont have a lot of time to waste trying to repair it.
try to reinstall flashtool after deleting it first .. install fastboot and flashmode drivers and drivers for ur device from drivers folder in flashtool folder.. disable any antivirus and any app that could interfere and unplug any usb device ... try to flash with flashmode
