relocking and going back to original state

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?

will Bravia Engine and TrackID work after relocking ?

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 :-

help please- locked bootloader, fastboot woes

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.

I dont think you have successfully unlock your bootloader. Your attempt was failed. If it says "Bootloader unlock allowed : No" then how can u unlock it? If u think u unlocked it then try relocking your bootloader using flashtools and flash ftf.

Thanks for reply
But i was sure to unlock my bootloader before flashing that custom kernel (Williams v5.1)
After flashing that kernel my phone bricked
I flashed stock kernel
My phone powered on but bootloader unlocking allow changed to no and my phone show "invalid card"

Is your phone carrier locked or not?
Just tell me which method you unlocked your bootloader(flashtools or adb).
This could be RIL isuue(or maybe I'm thinking too much).

To access any bootloader specific mode you will need to power down the device first before connecting it to a computer.
Therefore, please try again
Power down Xperia SP
Hold volume button UP for fastboot
Connect usb to Xperia SP

Just flash stock using flashmode(volume down) and boot stock ROM. Just check if SIM is working.
It can be that your SIM may have damaged so you check your SIM in some other phone.
I also see that you have no access to fastboot mode.I think the fastmode drivers are missing on your computer.
I can give you detailed steps if you want to know.

Installing TWRP?

I'm very new to all this, so if this is a stupid please forgive me.
I have a z3c with Android 4.4.4, I believe last night I've unlocked the bootloader via Sony's process. Phone rebooked and reset (and did see the green android doing stuff).
I want to install TWRP and then CM12.
Firstly, I can't seem to get into the standard (if there is one) bootloader by holding the volume button down.
Also, Is there a step by step guide to installing TWRP and some way of confirming I have actually unlocked the stock bootloader?
Regards.

use this code in the same way if you go to call *#*#7378423#*#* and check it on Service info configuration you should see something like this :
1 - bootloader unlock allowed: No
2- bootloader unlock allowed : Yes
3 -bootloader unlock: Yes
But for root the phone you don´t need unlock bootloader I don´t know in your country but here you lost warranty if you open it. You just need dowgrade to kitkat using flashtool, root with one script and you should to make a copy of TA partiton with other script and install dual recovery.
You have a lot of tutorials and videos arround.

I'm now following a post (DoomLord's) and trying to install CWM.
With the phone powered up and connected to PC, I can use adb and see a connection
I have tried getting into fastboot mode using two ways:
1. From adb and reboot in fastboot
2. Hold volume-up and connect usb....
I get a BLUE LED, but when using Android platform tools, "fastboot devices", none are shown....
I'm assuming blue LED means fastboot?
Note: I've turned on anti-virus / firewall... etc.
Basically, can't connect to phone via fastboot command....
Any ideas?

Final Solution ROM bricked(?) my phone?

Hi,
I just installed this rom:
http://forum.xda-developers.com/xperia-sp/development/final-solution-rom-lbl-t3073678
Everything went fine. I did all the steps. After installing the ROM and the fixes I chose system reboot from CWM Recovery. Since then I can't turn my phone on. If I press the power button there is a short vibration, but nothing happens.
1. Tried to reset with the button on the back of the phone. No go.
2. Tried all the button combination but can't even get back to recovery.
3. If I connect it to my computer then the led goes green and windows gives me that sound when you connect something new, but after 10 seconds the led turns off and I get the other sound for dismounting device. No diver can see it, neither flashtool does.
4. It doesn't charge. Well, at least the led does not turn on so I guess it's not charging.
Any idea?

You have a kernel problem, Flash with Flashtool the kernel of your rom in fastboot mode (Volume +, and connect your usb cable) with flashtool or if that don't available, flash a stock kernel in fastboot mode (Volume + and connect your usb cable at your phone), when it's flashed, restart your phone

Also which flashtool should work?

Normally, you can flash the kernel included in your rom, it's a file name boot.img, flashtool is good i think, can you send error messages with flashtool if you have any messages

I double checked that it works for locked bootloaded. It's even the name of the thread: [Final Solution ROM][UBL/LBL][V2][ODEXED for extreme smoothness][William's Kernel]
So the issue now is that I can't even install the driver (windows 10) as the device is being disconnected after 10 seconds of plugging in. I got the tft file now for the stock kernel and installed flashtool but it can't detect the phone (in that 10 secs), it says that driver is missing. Tried the C:\Flashtool\drivers\Flashtool-drivers.exe and selected the necessary drivers but it never succeeds. Attached the screenshot of the failure of installing the drivers.

you must start with phone turned off, fastboot doesnt work because you have hardlocked bootloader
pick stock ftf of your choice let it load and when it prompts you connect turned off phone with volume- pressed
then root it with towelroot and install super su, open it and update su binary
when you will be done with that contact me or respond to this post i will help you with next steps

OK, to be honest I don't get any of that. What is towelroot, how to install super su and how to update its binary? Also what do you mean "let it load" (ftf)?
I have to mention that the bootloader is locked because it can't be unlocked.

OK, to be honest I don't get any of that. What is towelroot, how to install super su and how to update its binary? Also what do you mean "let it load" (ftf)?

Yeah i know that your bootloader is not unlockable, by ftf loading i mean that select .ftf you want to flash first and wait until it prepares and prompts you to connect the phone, btw last flashtool that works with sp is flashtool-0.9.18.6 , if you will have problem with understanding that try to search how to flash ftf on xperia sp on youtube i hope you will get it eventually
towelroot is an app from geohot you can get it here https://towelroot.com/ it can root your device
super su is an app on google play it is free and it controls root apps, in other words it grants or denies root access, once you will gain root with towelroot, open super su and it will prompt you to update binary just select normal and it will work

I have version 0.9.19.10. And I can't select the file before I connect the phone with fastboot. The file has to be selected after. This is the tutorial I try to follow:
https://www.youtube.com/watch?v=IXTzA7Qrrv4
So my problem is still that I can't get into fastboot to flash the kernel. So towelroot and super su are not my options until I can't get into the system.
Any other clue on how to get it flashed?

you cant use fastboot with your bootloader locked that is the point there is NO WAY of flashing custom kernel with bootloader locked or you will brick your device, only way to flash kernel on lbl is to flash stock kernel in your case WITH FLASHTOOL TROUGH FLASHMODE

I understand what you are saying. But flashtool doesn't let me flash kernel in flash mode.
So it's a catch 22? After all this means that it's already bricked, isn't it?

You are not trying to flash kernel only, but that is possible too, you are trying to flash whole stock firmware.
Yes your phone is bricked because you flashed custom kernel on LBL.
Download some .205 or .207 firmware from android development section of xperia sp xda forum and flash it with flashtool.
There are plenty of tutorials online, i dont mean to be rude but you just must try and understand it yourself.
Here you have link for firmwares http://forum.xda-developers.com/showthread.php?t=2311964
just flash the ftf and phone should be ok, if you will be succesfull i can help you with rooting and flashing something suitable for locked bootloader xperia sp
Good luck

Wait a sec. It seems I could flash the kernel in flash mode.
It was keep disconnecting but finally the sony logo appeared and it booted to the system. It doesn't work properly, and it's very slow, but now I can get into CWM. Do you have any suggestion which ROM should I install on it?
