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 :-

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

I read through many threads and have followed the official Sony bootloader unlocking instructions. I have requested and received the unlock code from Sony via email. I have downloaded the inf file and placed it in the correct folder in Android SDK (which I also updated). But I am cannot access fastboot mode, I hold down Vol + and plug in the USB cable but the device shows a red led and goes into charging mode. Also the PC never prompts me to install fastboot driver it simply loads the SP as Sony mass storage device (in device manager).
I have read that some people seem to think that the SIM lock affects the ability to access fastboot but this SP is SIM unlocked. Sony's official guide to unlocking the bootloader says I need to access fastboot mode to enter the unlock code but how can I unlock the bootloader if I can't get into fastboot mode?
hmmm... don't know really... i once entered fastboot mode by mistake, while trying to root stock rom. wasn't reading instructions and put device in a fsatboot mode instead of debugging... was on stock rom so don't know if custom rom would let me do that. should check myself... if anything i know it is possible to get me that blue light shining.
To enter fastboot mode in Xperia SP just power down the phone and hold down the volume up key while pluging your phone into your pc
If you need flashmode do the same thing but with the volume DOWN button held down.
I´ve got the same problem. I can´t enter in flashmode neither in fastboot mode. I´m on windows 8 32bits and I installed the .245 Deodexed ROM with a problem on root and without CWM. I don´t know what to do now, please help me.
As I explained in the first post, I understand how to access fastboot mode (and flash mode). I got root and backed up the TA partition, the stock apps (from 1.257) and backed up the stock ROM. Then, after I wasn't able to get into fastboot, I have installed CWM for LB and flashed a custom ROM based on 2.245. I am able to enter flash mode but not fastboot. As I said before, the phone is SIM unlocked but is acting like it came from a carrier, with locked bootloader and fastboot disabled. How can Sony disable fastboot? I don't get it. Any one want to take a guess how long I will have to wait until some clever dev finds an exploit?

Sorry for that i dont think that it is your computers fault because you enter fastboot (and flashmode) using your mobile phone NOT your PC
So i would roughly assume that this is a Rom bug or something in the flashing proccess went wrong.

Thanks for trying to help, but I understand that flashmode and fastboot are accessed using the phone. Actually the phone needs a piece of software like flashtool to keep it in flashmode otherwise it drops into charging mode. I didn't mention my computer so I don't know where you got that from.
As I explained, I am unable to access fastboot with stock ROM (1.257) and a custom ROM (based on 2.245) so it can't be a ROM bug or the flashing process having gone wrong.
if it's not too much of a trouble for you, go and flash .245 stock, than .257 stock kernel only. like you are trying to root it for the first time, complete rooting procedure, and than proceed on to installing CWM, but instead of connecting device in debugging mode to install CWM, try and see if you can put it in a fastboot. this was exactly the moment when i accidentally put mine SP in fastboot. of course, i'm not saying to go ahead and install anything if you score, but only to confirm if you can put your device into a fastboot mode since installing anything without CWM will likely soft brick your device.
Same problem here, i can't do anything using flashtool after flashed 2.245. I did with SUS, maybe is some flashtool issue.

It may be a flashtool problem you are right because 2 incidents with different Roms that both use flashtool to flash those roms.....
its pretty much self explenatory.

Interesting. Ok, I've read up on the process. So I use the various stock .ftf files and flashtool with the phone in flash mode? Bear in mind that kernel didn't allow fastboot when I used it with the stock .257 ROM the device came with. If I do it, I will nandroid backup first, of course, but I think I remember reading in one thread that someone managed to soft brick their XSP doing this very thing.

that's why you need to complete rooting procedure. root stock 1.257 kernel, than back to stock 2.245 with root preserved, and before you would install CWM try to put device in a fastboot mode, this assuming you still have a UB.

have you tried to boot into android, open a root terminal and type

that should bring you straight into fastboot

All that happens is that the terminal session ends and closes (not FC) the terminal app. Using the same command via adb just does a standard reboot.
i just placed my in a fastboot mode, no problems whatsoever. do you have drivers for the device installed? you will find these in flashtool installation folder.

Yes. The fastboot_with_android_usb_file.rar package specified on DooMLoRD's bootloader unlocking/relocking appears to have been removed and there are no new links in that thread. So, I found and installed the drivers included with the flashtool. But it seems to be the device that is the problem. It is acting like a carrier locked model. I am rapidly starting to believe that this one has a locked bootloader.

Hi, I have some similar issues. I've also been flashing some stuff and whenever I try to go to fastboot it just boots into CWM. Very annoying to say the least. The dark blue light goes on when i hold down volume up and for a short moment I see the fastboot driver installing on my computer. But before it completes it's already in CWM.
Not sure what to do from here on wards, maybe some advice on which kernel to flash? I am pretty sure the latest kernel I flashed is the .254 root kernel from doomlord.
Ps. I really would like to flash CM when it becomes available as nightly :angel:
Thanks in advance!

I had already installed cm10.1 jb for my xperia ion.
Now i tried to install cm11 kitkat for my xperia ion.
Every thing is gone good.
But now got stuck up with a problem.
fast boot mode is active only for 5 seconds while connecting my xperia ion to System with flash tool.
help me to do the need ful.
Guide me to download compatible drivers and flash tool for fast booting process.
If you have UNLOCKABLE bootloader, then you dont have a FASTBOOT mode on your phone. Its just pure luck. some phones dont have it... kind of a sony crap... I also happen to be one of those LUCKY ppl. no unlock, so stuck with Stock kernel forever.
When you connect your phone to Flashtools in FLASHMODE...
See for a string BOOTLOADER: NOT_ROOTABLE.... it means you belong in the lucky group...
If it says rootable, then you're doing something wrong.
Pardon me if i read something incorrect. i skimmed through all the posts before posting.
picked up a Z1 and went straight to rooting it.
rooted succesfully, installed the dualrecovery, and then attempted ot install VANIR only to realize that i did not unlock the bootloader.
so it will not turn on. holding power it vibrates every 2 seconds. plugged in it does teh same, but also blinks red.
i can get the computer to recognize it several different ways.
blue led- fastboot interface in device manager - not detected in adb devices
red/green/blank led - SOMC flash - no adb
PC companion is no go.
I have no idea where to go from here. I am currently downloading flashtool to see where that gets me, but I was hoping someone might have some direct and well known solution that i did not uncover in my searching..
Thanks

He will not be able to enter recovery because dual recovery is system based which he cannot get to as its now trying to boot a custom kernel with a locked bootloader.
Also the recovery on a custom kernel is in the kernel, which also cannot boot. Hence a bootloop with no chance of recovery mode
The solution should be easy enough
Flash a stock FTF for your device using flashtool

Look in the general section for a sticky thread called FTF mega collection for the best FTF file for you.
Once you have flashed that then you should* root, then unlock the boot following the official sony instructions (http://bit.ly/1cebNlh).
once you have done that flash the boot.img of the rom you want to flash using fastboot them flash the update.zip in recovery
*The reason to root before unlocking the boot is to backup the DRM keys in your TA partition. If you do not do that you lose them forever.
Cannot get into recovery. Device seems to be bricked.
After Sony logo there is nothing else other than black screen. Please help me recover my device.
Don't Panic, this can easily be recovered. However the data that was inside I'm afraid is gone forever. Maybe it can be recovered maybe not, anyway I'm giving you some easy steps you can follow to recover your device.
1. Download Flashtool
2. Download the Firmware you want to load into the phone. (Search in the forum for .ftf ---make sure it is for Xperia Z --- files or you can download Xperifirm and make them on your own)
3. Once you have the .ftf file ready click on the Flash (Lightning) icon and select the firmware (.ftf) [Mode to flash is FLASHMODE]
4. When the phone is just one second from booting up (I know you are now in a cycle - loop but try as many times until you get it right), with the VOLUME DOWN button pressed connect it into the PC.
5. Wait for flash - About 10-15 min and you are done.
For any questions ask here. Good luck

I went through tthe threads and could find a workking method to unlock the bootloader. Sony has too many appps which I do not need, I want to get rid of them as it consumes a lot of batttery. Hence a custom Rom with basic stuffs arre the soolution.
If you can help me unlock my BL I'd be thankful
And one more question, does TWRP's Latest version only works for Unlocked BL ?

First, Try to do things in order!!!
You are very messy, first you needed to unbrick the device, now you want to unlock its BL and want to know if you can install TWRP!
Install a stock firmware, make sure you can unlock the phone (by checking in the settings menu)...
And post some info...
In your device, open the dialler and enter *#*#7378423#*#* to access the service menu.
Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

Good for you, for anyone who needs to install fastboot driver on windows 10, when they cannot install they need to disable windows driver signature:

I would like to know if there are custom kernels available for battery saving ? I flashed Zomie kernel and it was repeatedly booting my device into multirom recovery.
Right now I am on mokee, can I use any custom kernel with it ? If yes what ? I couldnt find many custom kernels for the device and what about Roms ? Not many custom Roms as well, only found RR and Mokee. Slim LP does not have a working link and couldnt find other popular roms too for this device.
I never tried new kernels, only thing install Kernel Adiutor and underclock, also change the governor mode.
As for the rom I use the modified stock rom by @androidexpert35, it provides good balance between performance and battery life. For any Rom you should write in their dedicated post. Keep experimenting but do it in a reasonable way and don't try to ask for everything, search and read others. Good luck
