I have been trying to unlock my bootloader for about a week, and i have tried many things and many methods, none which have worked for me though.
Info (in chronological order of how i tried to get my bootloader unlocked):
Update through LG software to 4.1.2 Jelly Bean, V20A (stock firmware and whatever)
Rooted my device (if this changes firmware then i have that firmware now)
attempted unlocking bootloader, and had no success....
Additional Info: Kernel 3.1.10-g0cf4eb
Build Number JZO54K
Baseband Version L6260_MODEM_SIC_02.1233.00
Software Version P88020a-234-000
Is a European model, and second hand and came from germany (live in UK)
I edited a picture to explain my problem, because i dont have any other camera than the one on my phone, which obviously i cant use whilest its like that.
This is where i get stuck when trying to unlock the bootloader. I accidentally unplugged the USB cable the one time after getting frustrated and saw that it actually started the 'next step?', Running Factory Reset For the first bootloader Unlock, please wait....
I plug the cable back in and waited overnight, and nothing happened, it stayed exactly the same. Ive tried every single USB port on my computer to no success. Please help!
Kindly edit your post with the solution method so of anyone has such a problem they can find the answer.

I had the same problem. I solved it using this method:

use the file in the bottom: BL-unlock_new.rar
Sorry,I have no that problem.
Same problem
Hello guys, I have same problem and even though its marked as [SOLVED], I dont see an answer here:/. Could anyone help me?
My phone has no network and it says no sim card. After further investigation it appears that this is because the IMEI number has just gone, it doesnt exist on the phone. It is standard I have never changed software so have no idea how this could happen. Tried factory reset but nothing works. Any ideas greatly appreciated.

Install es explorer or any root explorer
Install hex editor
In es explorer go to efs folder in root
Open nv_data.bin in hex editor
Goto position 00188020 and check. .

Try to pull dev/block/platform/sdhci-tegra.3/by-name/NVA
Open with text editor.
Check if imei is stored.
This partition is recreated on flashing dz/kdz. I am not sure if IMEI is read from here. If you give email i will send you my NVA partition to compare. Don't post it or people will see your IMEI

Thanks for your guidance...I have tried both option but it get stuck in middle somewhere and not able to flash the kdz file.
So at this moment LG Mobile support tools not able to cross 10% in firmware update process and stops due to some error.
With KDZ update tools, same situation....and device can connect to adb terminal no other recovery mode options.
So using adb terminal is there any chances to do some fix ?
I think I have currupted my boot loader during installation of third party recovery software without doing boot loader unlock option.
Please guide or suggest any other try.....
Thanks

It was happened like......the phone was working ok with latest official updates V20A and suddenly lost the IMEI number so Mobile network also. After some try finally I have done factory reset..but it was not working as expected...some time it has shown IMEI but lost also...tried many time factory reset but not worked...so tried with LG Mobile repair under upgrade and recovery option but it was failing at 10 % everytime. So thought lets intall new ROM so decided to install cyanogonmod so for preparation rooted phone and installed CWM recovery ....as doing all this first time so may be forgot to unlock the bootloader so after installation of CWM recovery phone has not booted and also not going to recovery menu. After that under upgrade mode tried to burn KDZ file using LG mobile support tool but that also not working.
So now the situation is, the can only go in to firmware update mode and some time getting connected to adb terminal.
So now is there any change of BL repair through adb terminal or the only option remain is visit LG support....?
Please guide....

Did you downloaded the files??
Install Drivers and follow the steps properly,
this should work for you to keep connected,
One more thing run drivers and flashtool as administrator, I already PM you.
Still having problems, please let me know.
If your phone is still not booting, I am afraid that you bricked it.
Good Luck

Hi
I am running stock 14.5.A.0.270, rooted and bootloader unlocked. Sony Xperia Z1
My camera app opens up, the camera button on the side of the phone even works. You push the capture area and front camera freezes and normal camera just shows me two buttons and won't do anything.
Please help I do not know what to do. There were a few other threads with a similar problem but I haven't found the resolution yet. Is it because bootloader is unlocked, I have read that I should restore the ta partition and relock my bootloader but I thought I will try here first.
I thought it would be fun rooting and flashing phones but so far just a big timewasting headache. I was on CM12.1 before , nightlies they were good but then it wouldn't recognise my sim card.
RR I tried but I got stuck on the bootloop.
Now I am back on a stock and my camera doesn't work
Help me please, I want to learn more
Many thanks for your time

Sorry I'm a bit late it seems but i had the exact same problem, camera wont focus and take pictures, video did still work depending on firmware but unfocused. Chances are your asking here because you lost your TA partition and DRM keys, which is most likely the cause
Solution:
make sure your phones bootloader is UNLOCKED
1. Grab flashtool
2. open Xperifirm via flashtool
3. look for 14.3.A.0.757 firmware (for journalists and media) (MUST be downloaded via xperifirm)
3. Download and unpack automatically, let flashtool do its thing til its ready
4. Relock your bootloader, DO NOT start your phone or touch your phone, keep it in flashmode
5. flash the firmware you just downloaded (14.3.A.0.757)
6. start your phone, camera SHOULD be working
7. Unlock bootloader and Flash any .ftf you like, tick EXCLUDE in the box that says .TA when you flash / if its available
8. Enjoy
I searched high and low for solution of my problem but i couldnt find the right solution to my problem that's why I'm starting this thread.
Phone- Xperia Sp C5302
Stock Kernel
Rooted
Philz Touch recovery installed
Nandroid backup made using TWRP
Tried to unlock bootloader- Problem starts from here........
Initially phone rebooted normally but couldn't detect sim and signal.
Then phone started rebooting after few minutes . Stay on for a while then reboot again till battery died.
Now battery not charging, phone showing no life, no led, no vol up+power, vol- power , vol up+vol down+power work
Tried everything I know plz help and plz explain slowly and calmly.
THANKS IN ADVANCE.
EDIT:
Used wall charger 2amp for charging left overnight no red led or anything as described in other posts
Connected to laptop left for about 4 hours no nothing.
Tried to connect in fast boot not detected.
Any more ideas guys at least give some pointer for what to do or is my Sp is actually dead ? And I can't restore my backup? Plz guys help
EDIT: Pressed the small button at the back and the phone came back to life YESSSSS........
Now the phone isn't showing imei no. or sim or network. But when restarted it imei and network came back magically. So I thought the problem is solved to confirm it I switched phone off again then switched on then imei and network gone again and also baseband isn't showing too (I'm sorry if it is the same thing I'm a newb to this stuff)
Then again I restarted the phone number it came again. I don't know what to do in this situation. I just wanted to unlock bootloader and install xenon hd rom in my Xperia Sp.

Try flashing stock ftf with Flashtool.
If the problem gets solved, then start with the new ROM.

Use the method answered by the previous post. But I will add into that
You can use the flashtool to flashing everything stock but please dont flash System and Kernel. If you flashed a custom recovery and want it to stay untick Fotakernel as well.
This should fix your problem without having to deal with the stock ROM.
But if problem persists then I would suggest a complete stock ROM flash.
Huge chance that the process of unlocking your bootloader is faulty. Are you sure that it went without errors? Anyway you might also wanto to try to relock and then unlock the bootloader again
@Zenith I left the phone idle for sometime now it's OK ish . I've made a nandroid backup but can u tell me plz which folder contains imei and other important stuff so I can make a backup of it too.
BTW I think my bootloader is not correctly unlocked coz pc companion is detecting my phone bravia engine is there gracenote is working. But in service menu under configuration I found: Bootloader unlocked: Yes.
Previously it was Bootloader unlock: Yes. So is it unlocked or not if not then how to unlock?
I've followed sony's official unlocking method.

You don't need to backup imei. It will stay the same no matter what ROM you use.
and You can use Titanium Backup to backup all your important apps and data. But do not backup/restore system apps.
and in the service menu;
"Bootloader Unlock allowed - Yes" means that your Bootloader is Locked, and you can unlock it.
"Bootloader Unlocked - Yes" means that your Bootloader is unlocked.
Bravia engine shouldn't work if your BL is unlocked, so something must have gone wrong in the process.
Follow what's said in post #4.
@Zenith Thank you for your wonderful suggestion i will do as u say. bt one big noob ques- Do i have to dload a ftf file to flash to stock cant i use my backup or someyhing from it to restore?
@TechnoSparks yeah i think you are right about my bootloader bt isnt there something to check if BL is unlocked correctly. Btw when i requested to unlock BL in fastboot nothing really happened apart from
<Bootloader > Unlock phone requested
OKAY [15.725s]
finished. total time: 15.725
Then restared approx every 10 min or so till battry went flat and phone being dead untill i reseted it via pin

Yes, you have to download the ftf file.
Use this one.
and don't use the latest version of Flashtool, use the "0.9.18.5" version.
@Zenith Thanks bro bt my model is C5302 will it be compatible?
And i just dloded 0.9.18.6 version. its not latest 0.9.19.0 ver is latest.
So do i have to dload again? (connection limited bandwith n slow speed)

You should flash ftf specified for C5302 then.
Download the C5302 variant that you prefer from here.
And try flashing with the Flashtool you have. If it doesn't work properly, then uninstall it, and install the 0.9.18.5 version.
Some members including me faced some problems on the next 2 versions of flashtool. So yeah..

Even you can flash C5303 ftf on C5302. I personally use Singapore variant .207. It has got least bugs and it is fast and much bloatware free.
P.S. Dont flash .201 it has got a lot of bugs.
Hi all, yesterday I flashed .101 using Flashtool (from .222) but the Flashtool binaries were corrupted and something went wrong and got bootloop. Today I used a different PC and at least it has been possible to install a custom ROM (.222) but the network is not working now. The PIN is requested but sometimes it fails and sometimes it just accept the PIN but there is no network. WiFi works fine. I have used this Xperia for more than a year and working well. My device is C6603 bootloader locked.
Thank you!

First of all, you can't flash a custom FW without unlocking the bootloader. If you so choose to unlock it, make sure you backup TA partition - it's used for DRM storage which is used for advanced camera functions (like noise canceling in pics, bravia engine and other sony stuff). Second just flash a proper FW with flashtool, wipe everything and see if it works.

Yes, you can flash a custom ROM based on stock with locked bootloader. It's what I have done successfully dozens of times, but my problem is as described in the OP, now I have a 5.1 android installation running well except the network data that doesn't work at all.

You could try to use sony pc companion to repair your phone. Sometimes, when it comes to corrupted data, flashtool won't do much good - it's something related to the TA partition that pc companion is good at fixing (I had some bootloops caused by bad root and flashtool couldn't help). You could try it and see if it works and if it does, use flashtool after to flash the rootable 5.02 and continue with the root.

OK, I just did it and didn't work, but this thing happened: Just after repair (using PC Companion) it booted and the text was chinese! I'm spanish, my PC language is spanish, my previous smartphone language was spanish... I don't know what is happening here but I thing this chinese thing is related to the SIM problem.

Somehow related but it isn't uncommon. I had an Xperia ZR bought from an official local retailer and when I opened the box I had a weird charger and first boot was in chinese. Sometimes they bring phones made for hong kong or signapore and sell them on european markets. 5.11 update might have different api s for the sim card, so different regions might not be compatible. This is only a speculation. Pc companion flashes the latest FW acording to your phone boot version, ets and customization. Imma PM you for more details.
