How to install recovery or cwm with locked bootlaoder

How kan i install recovery or cwm with bootloader locked.
My statu for unlocked bootloader is : no
Do You have one way to install this please

I don't think there is currently a way to do that. If you were to flash an unbranded firmware onto the phone would that allow you to unlock the bootloader (allowing installation of CWM)? I can't unlock my bootloader due to my PC being broken.

I'm waiting for a solution as well. it should not be that hard as they have a solution for the xperia s with a locked bootloader.
maybe some very wise and helpful dev can port cwm for us xperia t owners with locked bootloaders.

Flashing unbranded firmware will not allow you to unlock the bootloader if you currently cannot unlock it.

Well, no promises of any kind, but there is that one user which claims that after updating to 3.195 the bootloader status changed from non-unlockable to unlockable.
I have to stress out, I cannot confirm nor explain this and I do not propose that anybody tries this.
But we all know where this is going, right...? Sic...

Its safe to try, as long as you have a .ftf made from your original rom or are prepared to flash one the .303 .ftf's found in the all in one thread

I've flash one week later the 3.195 and my statue dont change.

For people with the lock bootloader cant you unlock it through the official Sony site? i thought Sony allows you to unlock bootloaders on their devices...

Sony does, but some carriers (Especially AT&T) block it.

You can ask, but I bet they say no.

up to date, any method to unlock it?

Seriously?

I also have this problem, the boot loader is locked and I need to install the recovery. Prompt really working bootloader unlock method, none of the methods I did not ride. Through the website Sony have an error occurs, full of requests to install the update file, it weighs 1.5 gigabytes. I do not have as much Internet traffic to download it.

Currenty is possible if you are both rooted and in FW 303. Try this.

Lets get this damn bootloader unlocked! (234-000 and other non EUR-XXX)

The other 234-000 thread seems lost. As official cm10 has come we need to get unlocked if possible. The purpose of this thread is simple, 234-000 users, post all methods you have tried, and whether there was success/failure, or anything wierd happened. This will help us rule out different methods and find the right one if one exists. Please only post here if you are 234-000 or other locked model. I'll begin:
Tried flashing china v20b, adb reboot oem-unlock just gave normal reboot
Tried HK v20b, same result as euro rom, security error
Tried on euro v20a the following:
Standard method: Security error
Wait 2 hours connected to "real network": security error
Do command from recovery: adb reboot oem-unlock = error, closed
Tried changing persist_sys_country to EU, still got security error
Sent from my rooted P880

I tried unlocking it on Orange/EE and Three. No luck until now...

262-000 here
using a Vodafone Malta sim
connecting to real network i assumed it just means having reception
did not try with 3G on since its quite expensive on my network
tried using adb reboot oem-unlock I get a security error
adb reboot bootloader -> fastboot oem unlock
I get the option to unlock and press it but when i check from hidden menu it still says Lock.
Tried these two options while being both rooted and not rooted. Also tried with MLT enabled and disabled.
Finally I also tried to unlock using euro open v20a and Germany v20a.
Would really like to run CM10.1

Tried on T-mobile including everything non4 has mentioned.
Also tried downgrading, upgrading using kdz updater, lg flash tool but not the pc suite hack (which seems to be the method for those who got it to work) as I can't get it to work for me.
I've noticed in the hidden menu that under SIM test you can enter details for a virtual sim and was going to try using a MCC & MNC code for a EUR XXX country and try re flashing 20A with that set but haven't got around to it yet.
Now we've got official CM10.1 I'm desperate to get this unlocked!

Downgraded to V10H with LG Flash Tool, Then upgraded to V20A with KDZ Updater,
Left for 12 hours on mobile network (Never connected to wifi)
Re-flashed several firmwares. Tried Germany European firmware, tried every command that could possibly unlock the bootloader. After each reboot i have left it for 2 hours on mobile network.
Still keep getting [LGE SECURITY] Unlock Permission Denied.
LG's open source team tell me i should go to an LG Service centre and get the binary image reset (Which we can do with KDZ Updater or LG Flash tool) Other users recommend we wait for AGBRBK_V20A for our device. Doesn't explain how i know 2 other users running 234-000 V20A with unlocked boot loaders...
I would like to ask whether anyone else had flashed the Leaked KDZ files, what their boot loader lock state is and the software version.
Example from me:
Flashed V20A Leaked image - Yes
Software version - V20A_234-000
B/L lock status - Lock

234-000 Uk v20a (I think?? It came on the phone)
3G waited 2 hours and got security error

I think they do but for some reasons some devices are not allowed to be unlocked due to carrier limitations... hopefully these politics will change...

Well they sent me a mail saying many uk carriers had concerns so they kept it locked for now. As UK rom is forbidden this may be why, because they also said they are in contact with HQ for a better solution. Maybe we'll end up with a flash counter like Samsung or something, but as people did get 234-000 unlocked in sone cases we gotta keep trying, I'm out of ideas though

May be worth trying that address to see what response you get.

first we need to know a mmc and mnc from a EUR - XXX Phone.
Then we should put out our sim.
Goto hidden menü and use a virtual sim.
than flash EUROPEN ROm with flashtool to eraese everthing.
maybe it works then

Problem About Bootloader unlocking

So its my first time, got it in FastBoot AP Flash Mode (secure boot off)
Have latest drivers, and opened cmd in the Razri_Root_Windows folder and typed the code, it said "Could not get unlock code"
I Still havent download Android SDK..so yeah maybe thats it..

Yes you need either the Android SDK or the root zip that people are using. Have you unlocked any smartphone bootloader before?

Nope not yet. My first phone is a SAMSUNG Galaxy Ace Plus and it didnt needed unlocked bootloader.

If I flash a new firmware I might be able to get the code.

[Q] Cant get the bootloader unlocked, please help :)

Hello again all peeps!
I need helpeth! I cant unlock the bootloader, nothing works.
First I cant get the status options from *#*#7378423#*#* , it just says the number isnt working. I got that menu when I started this a couple of days ago but I cant get them now so I cant check if my phone is unlockable.
Second, the command for unlocking the boatloader with the command: "fastboot.exe -i 0x0fce oem unlock 0xKEY" doesnt work, it says: "FAILED (remote: Command not allowed)" .
Third; I downloaded latest flashtool and tried that but it feels kinda scary since the threads says it only works for x10, x8, x10 mini/pro.
´So what shall I do at this time?? What to do`?

Is your device unlockable?
Like does it say bootloader unlockable = Yes on the service menu?

From a unrooted state due to root can change status sometimes

How do I check this out? With this command: *#*#7378423#*#* ? That one has only worked once, when I rooted the phone, otherwise it doesnt.
And the phone is rooted I think, otherwise the TA backup wouldnt have worked I guess

I must agree... If it's Carrier locked phone, you can't unlock your bootloader either vía flashtools or fastboot.
Sorry, but only sony's service centers can do it...

Argh, wtf! The other Android devices I bought where always available to "crack" on some way but I guess there isnt a way now... :/ I hope there will come in the future
Anyway, I have root now anyway. I guess I can install some roms anyway

Any idea if someone is working on a boot loader unlock for the c6606 I'm kind of annoyed. I have it rooted and debloated but I want to flash other Roms.

Indeed you can. As long as they are stock based and planned for locked bootloader...
The only issue IMO is that you can't flash other kernel than mentioned STOCK based ones
Enviado desde mi C6603 usando Tapatalk 2

What about updates? I won't get ota updates if I flash it right? I'm stock rooted at the moment

If you finally unlock the bootloader, you will surelly face OTA issues, and probably a soft brick. You will have to use Emma from Sony. It's meant for unlocked.devices...
But first of all, make a BACKUP of your ta partition, or you Will loose your drm Keys.
You have been warned

Simple.. As long as you don't tick DATA, your firmware should be upgraded instead of deleted...
You can preserve root If you don't tick kernel also (i think)

You've got a locked, un-unlockable bootloader. This is what you get when you send the unlock command in fastboot in this scenario. The oem unlock command is not allowed. This comes from experience of my C6603 on Three UK. Go check the Xperia bounty thread for a ton of information. ( http://forum.xda-developers.com/showthread.php?t=2287897 ) Doomlord is working on a workaround for this when he doesn't have other dev work to do.
Upshot of this is that you can't flash kernels that aren't signed by Sony. This rules out CM and anything using CM as a base. It is very annoying but at present only stock based roms are flashable.

I just read his instructions more carefully so now I know that since I have the same firmware (10.3.A.0.423) as his rom so I can just install it via TWRP

help me unlock my bootloader

Hey guys last days im started looking how unlock my c6602 and i cant find any way that work for me
I tried doomlord way and didnt worked what i did:
1-Got my bootloader key from sony
2-connected my phone in fastboot mode to my pc
3-opend command window in the place i installed fastboot drivers
4-typed: FASTBOOT.EXE -I 0X0FCE GETVAR VERSION then enter i got VERSION:0.5
5-typed:FASTBOOT.EXE -I 0X0FCE OEM UNLOCK 0X************
6-i got that error :invalit id (0x**************)
I checked the number many times and it was currect SO WHY???
I tried flashtool to unlock and i got that (failed remote: command did not success)
Is sevice menu says bootloader unlock allowed: yes
Is there any solution for that??
Running:4.3 stock %100
EDIT: today tried again in command window AND NOW EVERY TIME I THY THAT SAYS failed remote: command did not success)!!!!!:crying:

I said this to you when you asked in the bootloader unlock thread, but you didn't respond or acknowledge my reply.
The unlock key is case sensitive. Meaning that any letters that are upper case (capital letters) must be entered in upper case. So E must be entered as E, not e.
If you don't enter the unlock key exactly how they sent it to you, it will not work.
If it still won't work, maybe you entered your IMEI incorrectly when requesting the unlock key. Try requesting it again and double check the IMEI when you enter it into the form, as a key generated for the incorrect IMEI also will not work.

Anyway i bored of that unlocking story now im trying to get perooted rom

Well, you're definitely doing something wrong. Both Flashtool and fastboot work for unlocking the bootloader for everyone else.
From your screenshot in the bootloader unlock thread, you were entering the key with all lower case characters, which was probably wrong if you're now entering some upper case characters. Enter it EXACTLY how it is in the email.
Anyway, good luck flashing any rom without root. You'll need root to install a recovery.

Are you deliberately not reading what I'm telling you or something?
You'll need root to install a recovery to flash that rom. If you don't want to unlock your bootloader, you will need to downgrade to a 4.2.2 stock rom.

I tried it on 4.3 and 4.2. The bootloader unlock allowed says yes.
