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...

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.

[Q] bootloader not allowed xperia z

my phone is showing me that it cant unlock boot loader when i see in service test bt typing *#7378432#*#*
i am from india and using normal xperia z (not any docomo or any)
can any one say what to do for getting permission for unlocking boot loader

Short answer - you can't unlock it ever.
The only exception would be if the status changed to disallowed after rooting. There is a fix for that somewhere in Doomlord's rooting thread.

First time I checked, I was also disappointed, a few days later I realized that I checked the status without having a root phone. After I rooted the phone it said yes for me.

Short answer:
If your device says Bootloader Unlock Allowed: No, it means you CAN'T unlock your bootloader.

Unless it was rooted, as this sometimes changes the status to 'No' as stated in the first post of Doomlord's thread. I used bin4ry's tool and the bootloader status was untouched.
Edit:

if u had an unlockable bootloader device, after using this method the device will be detected as LOCKED or unlock not possible!!! (to fix this use this fix)
...........
Troubleshooting:
if your device has unlockable bootloader then after applying this hack the bootloader status will turn "Bootloader unlock allowed: No"
in that case dont worry the users have reported that doing a repair via SEUS will flash back stock firmware and turn this status to "Bootloader unlock allowed: Yes" (the same might also be achieved by flashing a stock FTF using FlashTool )

Hello, everyone.
I know nothing about rooting, flashing or unlocking bootloader. What I really need is to unlock the network of my phone. It was bought in Portugal locked to the TMN network. I am now back to Brazil and want to use it here. The conventional method of unlocking network is buying a code, but I want to know if there's a way to do it with no expense. What do you guys recommend?

Hello and welcome to the forums.
The only way to network unlock this device is with a code, either from the original network provider or from an online seller. It is not possible to unlock any other way.
Additionally, as you're new here, I will suggest you should start a new thread when you have a question in future instead of bumping a very old thread unrelated to your question.

Hi, welcome to the forums.
This is the Xperia Z section. You should ask questions regarding the Xperia Z3 in the Xperia Z3 Q&A, Help & Troubleshooting forum.
Sent from my C6603

I'm thankful that there are still wanting to address this issue of the bootloader not being unlocked. So my question is as such - Is there anyway (either by contacting T-Mobile, or Sony) that my phone, which is is SIM Unlocked (I know SIM unlock has nothing to do with bootloader unlock), can be bootloader unlocked? I'm just hoping that I can either get with Sony/Tmobile and have them do it, or even if there is a legitimate paid service out there then I will do that too! Any kind of help or anything would be appreciated! All I read is, 'If you're bootloader says no than that means NO', or I will often see people say that their bootloader says no and yet they can still enter fastboot mode.
Currently my device is Sony Xperia Z C6606 Tmobile version. I'm going to try to switch out my microUSB cord and see if fastboot works then. I'm still trying to have some kind of hope that maybe it will somehow work and I can flash a custom rom. Currently, whenever I plug in my phone into any computer, (with drivers installed) it never even shows up in the Device manager so I'm thinking it's an issue with my cord. It charges the device only.
Or should I just sell this phone and get a different android phone where I can unlock the bootloader? lol
Thanks!

You can only flash stock based roms with a stock, unmodified kernel.
Fastboot will connect even with a locked bootloader, but the commands you can use are extremely limited and in your case you cannot do anything with it at all. Your USB cable is not the problem.
If you want to flash CM/PA/AOSP etc, then you'll have to buy a new device. The bootloader is non unlockable. Nobody has cracked the security yet and I don't think anyone is even working on it, to be honest.
Sony or T-Mobile will not unlock it.

[Q] Bravia Engine - Is it worth it?

Hi, my bootloader is suddenly unlockable since the .244 firmware update from Sony. So my question is this: is it worth losing the Bravia Engine by unlocking my bootloader? Is the Bravia Engine really a feature worth having on the XZ and are there any substitutes?

If your Phone came from a carrier then it isn't unlockable regardless of the change in status.

Sad news :crying: thanks. XperienceD what's your take on Bravia anyway? Is it worth keeping a locked bootloader for Bravia Engine?

I unlocked my bootloader as soon as I got my phone. I would rather have an unlocked bootloader so I have the ability to flash custom roms and kernels then seen the colours a little brighter when watching videos and viewing pictures.

Yeah well the biggest downside to locked bootloader is no chance of AOSP roms :crying: luckily most of the Xperia's UI is pretty cool, particularly the Honami email, messaging and contacts. So after XperienceD's news about bootloader being locked if the handset came from a carrier, I can live with it for now... gonna try unlock it anyway

I'd prefer to keep it but would happily sacrifice it for the ability to be able to unlock my BL. You can try for nothing but if it does come from a carrier then I've yet to see anyone who has reported this change in status then go on to unlock it. I'll never have another Phone from a carrier that's for sure.

Is it worth?
Simply. Yes. That's my opinion.
Btw, I unlocked bootloader and I still have BE2, all these DRM keys. Is it normal?

Seems http://unlockbootloader.sonymobile.com/ is intermittently down tonight loaded the web page earlier but can't load it now. Will check it out tomorrow, my phone is from Vodacom so it's a carrier phone.. this will be an interesting test. Is it normal for Sonymobile website to be down? "The website encountered an unexpected error. Please try again later." Poor show if it is..

It worked, unlocked my bootloader with a carrier issued handset I bought my phone from a dude when it was three months old. It came from Vodacom. It had the Vodafone logo splash screen when booting from stock and he showed me a photo of the registration screen at Vodacom when he picked it up. So I assume it was a carrier issued handset. Anyway, seems all is well now :highfive:

I flashed .244 stock firmware in Flashtools and now it's fine. But I can't flash custom kernel, so I suppose that means my bootloader is still locked? But when I unlocked it, it said successful

Hey XperienceD, dunno how this happened. My bootloader changed from a status of unlock not allowed to unlock allowed after I flashed .244. Now I managed to unlock the bootloader, and it's a carrier phone from Vodacom in South Africa. Strange but true :victory:

Fastboot issues,bootloader (un)locked?

So I've unlocked the bootloader on my xperia Z the official way. Entered the unlock key and it was successful.
However, if I try to write a recovery in fastboot I get the error : Remote: not allowed.
I have made sure I have the correct drivers and all but it still doesn't work. Even tried unlocking it again with a second unlock key.
How can I fix this?

Unlock bootloader without losing DRM keys
Hey guys
I have a similar problem. I want to flash DoomLord's custom kernel but the command is not allowed. I found out bootloader unlock allowed does not mean it is unlocked yet, so that is the problem why it is not allowed. However, I do want to backup my DRM keys first. Is this possible? My phone was rooted before I flashed 4.3, so it is not rooted anymore.
Oh I have a Xperia Z 4.3 c6603 flashed with the ftf supplied by doomlord.

just checked the screenshot says that BL unlock allowed: status YES which define that ur BL (bootloader) is not unlocked yet!
make sure u are using the appropriate tool that works for ur device after u get the BL code from Sony, then follow the instructions in Sony where u got the information about unlocking BL
first off... do not proceed with bl unlock until you backup your TA partition cuz u might brick ur phone after the unlock is done if something goes wrong!
is it's not really recommended... u can still root it with a locked bl and enjoy ROOT privileges... FYI, unlocking bl will erase DRM keys and might affect on ur TA partition too.... so keep in mind that Bravia Engine2 along with Track ID will stop working after unlocking ur BL

Xperia LT30at: Root, Unlock and Remove AT&T Apps?

In general, I would like ask about unlocking my Xperia LT30AT. I've unlocked a phone before but it has been a long time.
I seem to recall that when I unlocked my first phone, I downloaded a developer kit that you use to root and unlock the device. I am interested in doing that to my LT30at, but I don't want to use any custom roms like Cyanogenmod.
What I would like most of all to do: to
(1) root and unlock the phone,
(2) keep the (functionally) authentic Android OS, and
(3) Get all the AT&T apps off the phone for good.
...but I would settle for just the first one, for starters.
Any suggestions? Thanks! MX

In addition I wanted to know if you lose your 4G LTE Thanks to all who respond
* P.S. many links to files in the root of the sony t is no longer usable

To root this device you should use the flashtool, you can't unlock bootloader at all. Me I rooted it added a recovery. Then flashed a unbranded firmware via the. Recovery. Kept root that caused everything to work pretty Ok now my att TL is rooted with 4.3 with a few bugs

Since you want the phone to be rooted, you have only 2 options:
1) If you want to stay on 4.1.2: flash any generic 4.1.2 FTF using Flashtool and exclude the baseband in the process, then root the device.
2) If you want to upgrade to 4.3: follow the guide in my signature.
Bootloader cannot be unlocked.

If you update to 4.3 using Flashtool you will lose root access to the device because there is no exploit available yet. Carrier lock is SIM lock and is managed separately from ROMs.

Are you sure it's "bootliader unlock allowed: yes"? LT30at have always come with locked bootloader.

Yes , Bootloader unlock allowed in my device is YES . Firmware is 9.1.F.1.120 , android 4.1.2
So can i update my device to 4.3 ?

You're probably the first person I've seen with a TL with at&t firmware (I'm assuming since it's 120 firmware) that has an unlockable bootloader.

Yea I must 2nd that how did that happen
