Well.I just got a used.Sony z
I.rooted. Via.one click. And installed twrp with the apk.
My question is can we flash roms without no issues even with a lock bootloader on this device seeing as I opted out to flash recovery with the locked bootloader and if that's not the case how do I find out if my bootloader is unlockable version

If you are locked, you just need to flash roms flashable zips via recovery. Look for "LB", which stands for Locked Bootloader, threads under the Development section, and you'll find compatible software with your unlocked device.
If your device is from a carrier, chances are you are locked with no way to unlock. If your device number is C6606, you are not able to unlock, no matter what.

If your bootloader is locked and you can't unlock it you can still flash roms but only those bases on stock. The problem with the locked bootloader is that you can't install a kernel that isn't signed by Sony. So no CyanogenMod and derivatives.

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
Sent from my LT30p using xda app-developers app
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.
Hey guys, with the no bootloader unlock exploit, i could obtain root without unlocking the bootloader.
However, i just want to ask, will the root still be kept if i flash on a different rom, or flash on the new FTF 434 firmware?
Thanks :3

It is possible to flash roms on locked bootloader devices. Wait till the devs support it. The xperia s has roms for locked bootloaders.
there is already a locked bootloader CWM recovery available. so i would imagine that you can flash stock based roms..
Hey,
I just had a thought this morning regarding the situation with Locked bootloader's that can't be unlocked is it possible to flash a stock ftf file which originally allowed the bootloader to be unlocked to a locked phone, if it is possible using this method can someone give me a stock ftf which has the original unlockable bootloader and I will try it.
I hope someone knows the answer to my question
You can flash the FTF, but it will not make a non-unlockable bootloader into an unlockable one. It is not that simple. If it was, don't you think it would be common knowledge and the recommended course of action?

After of a few hours of driver issues (adb windows 8 sony xperia z too) I have managed to make them all work.
I tried root without unlocking, no luck with that method
I tried unlocking with flashtool, It said "Done", my first doubt is how I can check my bootloader is unlocked?
After this I tried unlocking with the official way (sony, and I got bootloop,on sony animation logo)
So I had to flash the 10.3.A.0.423 (the one I had previously which I flashed it with flashtool)
Now I think pictures look a bit worse because I have unlocked the bootloader and I have lost the Bravia Engine but maybe its just me, how can I check if I have unlocked succesfully my phone? If I have unlocked it I have lost the BE? I tried to save it with no luck because I wasn't root
How can I succesfully install a recovery for installing another rom? all the tutorials aren't working for me neither the locked recovery cwm or the unlocked one..
Can someone link me to other tutorials?
The order is Root, Unlock, Recovery?
Flash doom kernel with fastboot,it has root and recovery.
If it's successfully flashed that means you have an unlocked bootloader.

Hey all,
I've been using my Xperia T on the Rogers network here in Canada for a couple months and wanted to throw a custom rom on it.
After doing some research unfortunately it is Not possible to unlock my bootloader. There is also no way to boot into "Recovery Mode" which I assume has something to do with the locked bootloader.
I've noticed that you can downgrade to .303 but those roms look like they are for LT30p. Will they work with my LT30a?
I was hoping to get a version of CM on my phone. Is it even possible? I've read that maybe I can load certain roms but will be unable to modify the kernel? Will that work ok?
Thanks for you time!

if you are willing to go for CM then the answer is NO. you need to have a BL unlocked device with you. did you check with http://unlockbootloader.sonymobile.com ? and your mobile as well to confirm whether it is unlock-able or not. Check Here ..
but even with a locked BL you can install custom ROMs to spice your device. there are some ROMs which are specifically designed to be used with locked BLs.. that means they will run on Stock Kernel with customer ROMs.. .. for my LT30at (BL locked) i'm using a custom ROM
Yes it is indeed locked and cannot be unlocked. There's one Rom for my device I saw but it looked dated.
Rom suggestions for a locked bootloader?

You should be able to use any of the custom ROMs in the development section for locked bootloaders. I have an LT30at and I have used all of the ones in there at different times.

So I made it as far as rooting the phone, installing a version of CWM for locked bootladers. But after tying to install two different ROMS for locked bootloaders they both put me into a SONY boot loop that seemed like it would never end.

ok did you go through the CWM menu and wipe the system, data, dalvik cache and so on... before you flashed the rom?
It often takes allot longer to boot up for the first time but no more than... id say 5 minuets if that
