hey i cannot unlockbootloader in service info bootloader not allowed which frimeware i can unlock bootloader?
hi there,
if the phone says in the service menu bootloader unlock allowed no means it cant be unlocked but that means you can still install a custom rom which should say LBL rom. Follow this guide: http://forum.xda-developers.com/xperia-sp/general/guide-flashing-custom-roms-ultimate-xsp-t2888579

Go to Xperia website, and search Unlock Bootloader, there you can select Xperia SP and see the number code type it on your cell phone to see if your cell can unlock the bootloader ( My English is more less bad, sorry for this I am Brazilian )

If it says "no." you can't unlock it. You can install custom ROMs as long they are stated that are for Locked Bootloders. Do not attempt to flash a ULB ROM onto a Xperia SP with a LBL because it will soft brick your phone. Attempting to unlock the bootloader when the the status says "no" it's not recommendable and could hard brick your phone.

As mentioned above, if the phone says "no" or doesn't say anything at "bootloader unlock allowed:" thing, then there's no way around that. You can still get custom roms though. There are some roms that will work with locked bootloaders.
Pro tip: Always buy generic phones if you want the best from xda. Always check what you're going to buy.

Hello guys,
Well... I guess I got one of the dumbest operator rom ever made for XZ (guess it's the same as Vodafone's one), so I wanna root it to get a recovery and then flash any kind of others roms but it's still weird..
By typing *#*#7378423#*#* => Service Info => Configuration ; I was (and I'm still) on the "Rooting Status : Bootloader unlock allowed : No"
So, I do Install the ADB Drivers from this Thread
Then I try the Binary's script, but still no reaction on the 2nd step (yeah I do launch it as administrator), and then I use the DoomLord'd recovery for locked bootloader
So now, I got the CWM 6.0.2.8 recovery on my phone, but I still got the "Rooting Status : Bootloader unlock allowed : No"
Well... I just dunno where I am... Do I am rooted ? Can I flash a custom rom ?
Help

Frnd, Make ur basics clear.. Rooting different from installing custom roms. To install a custom rom u need to unlock the bootloader first. But to root your device, you dont need the same.. Please search the forum once again.. u'll get the answer

I do check what I can since weeks now, and wait till safer way get released (seems cool now ?..)
So I do try the "official" way from sony to unlock the bootloader who just tell me "lol Bootloader unlock allowed : No"
Then.. I would like to unlock the bootloader yeah...
What do I mean to learn ? for now : locked bootloader will stay locked... (I'm still in that feelin that nothin is impossible)
So yeah I search on the forum to "make my basics clear" ; here we go => Usefull forum search
So, what I meant to learn now => I just can be rooted for now, but the Bin4ry's script don't work for me and I still dunno why
But... I success to get the CWM recovery on my phone through DoomLord'd recovery for locked bootloader
Questions was :
Can i flash a custom rom through CWM ? y/n ?
Usually on my previous phones (HTC Leo, HTC Desire, Samsung G2, Samsung Galaxy Nexus) as soon I can get the CWM on my phone mean that I'm rooted, so ?....
You can flash roms that are for locked bootloaders, they are usually indicated by [LB] in the dev threads. The bootloader unlock allowed status for your device will remain no, root does not magically allow you to unlock your bootloader.

Howsit Guys
Need a lil help here. Im currently on firmware- 10.4.1.B.0.101 with [Root & XZDR] http://forum.xda-developers.com/showthread.php?t=2643898 <-- via this method.. all Works sweetly.. Problem is that i want to unlock my bootloader. Ive checked in the service menu, unlocked bootloader is allowed.
I am currently trying to unlock bootloader with latest version of Flashtools(unofficial way).whilst phone is on, i connect cable, startup flashtools, it detects device. Then i click on lightningbolt icon, to unlock bootloader. menu comes up asking to remove cable, power off phone n goto flashmode.
When i get to the part where it asks to select my device, i click on xperia z. And i get a FAIL message saying i cannot officially unlock bootloader?? Do i need to be on stock .244 firmware or stock kernal to unlock ? Or am i going through it the wrong way. main reason i want unlock bootloader to install cyanagen mod11 nightly.
Thnx
Done
Sorry for the silly post.. managed to unlock my bootloader..

go ahead with dual recovery. it won't brick your phone.
locked means it can be installed in locked bootloader.
unlocking bootloader lets you install custom roms like cyanogenmod, omnirom etc which are close to stock android something like in nexus devices.

okaay so i rooted my phone again and decided to unlock my bootloader, i have verified that i am able to unlock my bootloader and follow all the instructions on the official sony website on how to unlock the bootloader. i get no errors during the cmd process either, i turn my phone on and it gets to the purple boot animation screen and then freezes. Is there anyway around this ?
EDIT: Also i used DooMlords thread and get the same problem? /: - I also use Flashtool but when i press 'blu' i only have the option to RELOCK my bootloader? :S
Anyone ? /: been looking for the solution all day

Just flash any desired custom form via fastboot and that's all, it should work.
When I unlocked my bootloader with stock firmware it doesn't boot anymore either, so I had to flash any other or reflash it again

Just flash a official FTF, then go to service menu, tests -> configuration and if your bootloader status is:
Unlock allowed: Yes - you can unlock your bootloader
Unlock allowed: No - your bootloader is hard bricked and there's no way to solve this (permanently)
Unlocked - congratulations.
I suppose your bootloader is hardlocked. check for yourself and if anything changes - quote

it says ---> Bootloader Unlocked: Yes. But iv'e tried to multiple times and still get stuck at the animation screen on boot up
If you are on a custom rom you just have to flash the custom kernel over it putting the phone in fastboot . No need to unlock bootloader again. Please ensure that the rom supports the custom kernel or there can be bootloops .

I have tried unlocking it with and without a custom ROM on my phone, it says 'Bootloader Unlocked: Yes' on the service info and i also only have the option to RELOCK my bootloader when i try it on the flash tool. Does this mean that it may actually be unlocked already?
EDIT: im also using This custom ROM which has custom kernals to select from
-Thanks

The rom that you gave link to is a stock firmware based custom rom, so it will have stock kernel.
I think it must be written Bootloader unlock allowed: Yes, on your phone
You will need to unlock the bootloader, PM me I will guide you how to do it.

Messaged you mate ☺
Issue fixed thanks to androidtweaker1 - even put me on DU lollipop!
good afternoon, I have a problem with my xperia z1 c6903 when unlocking the bootloader I get a message that says your phone can not be officially unlocked that I should thank.
Apparently Sony has blocked the ability to unlock the bootloader on certain devices.
This is most likely the case if you got your phone from your carrier. Do you have a branded Z1?
You can also look up if this is the case by doing the following:
1. Open dialler and enter *#*#7378423#*#*
2. Go to Service info > Configuration > Rooting Status.
3. "Bootloader unlock allowed" should say Yes
If it doesn't, then at least the official way of unlocking your device won't work.
Any "not official" way to unlock the bootloader? Mine is locked too and i want to install something new in that old one. Thanks in advance.
Mine says not posible but i read somewere that can be done
That's the thing, is an old smartphone today, i don't understand why only certains models can be unlocked. Now im on last oficial os (5.1.1). I get it root but i cant unlock the bootloader in any way.
