[Q] Locked Bootloader

I unlocked my bootloader using the sony unlocking process. As it was saying my phone couldn't be updated due to modified software, I flashed a stock uk unbranded rom on to it (mine phone is a 6602 bought in Qatar, but the firmware says it's for a 6603).
I then used the flashtool to lock my bootloader. When I check the service settings it now says that unlocking the bootloader is now showing as no. Reading another thread that said by using the SEUS to repair your phone it's possible to change it back to yes, I tried it, but SEUS says that it there is no software available for my phone. Sony Update Engine doesn't have software available for my phone'
Anyone able to get my bootloader unlocked again?

Xperia Z Bootloader unlock issues help

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..

ok this might be a bit too many questions

hi all,
i have recently aquired Sony Xperie SP C5303, and i now i'm lost since i never had android phone. all i used was various emulators for PC and stuff...
but now there is many stuff to be noisy about. and probably this has been answered many times but please, do me a favor and pretty please answer again if possible.
1. Phone is SIM locked (i'm working on getting unlock code from provider, since i have right to do so, after contract expires..which has)..but is there any way to unlock phone before i get the code? i'm wondering how technitians in local services do that. they ask about 30€ for unlocking device, and i doubt they have acces to provider's unlock code.
2. I tried to flash phone with custom firmware (using flashtool) but it failed on me even though i used right firmware, and phone bricked. however i managed to recover phone with sony PC companion and it now works same as when i got it. Firmware 12. 1. A. 1. 205, android version 4.3. i have no idea why it failed on me during flash. can it be cause phone is no rooted, and have no root support? (whill connect to this on 3.) do i have to root phone before flashing? i would really like to have root access.
3. i was unable to do hard reset of phone with power + volume down button. or any other trick didn't work. i couldn't not enter android recovery options. i followed instruction on how to root my phone on
Code:
developersonymobile(dotcom)/unlockbootloader/unlock-yourboot-loader/
. i entered
Code:
*#*#7378423#*#*
to check if my device is unlockable, it says boot loader unlock allowed : No. Does this mean i won't be able to have root acces on my phone? or i still have to learn difference between terms or what they mean.
also is that really true what they warn about that there is no turning back after i root phone and all. won't just hard reseting phone or repair device with all defaults troubh pc sofware bring back and vipe everything back? how will than service know if phone has been rooted ever?
thank you in advance for all your answers.
"Bootloader unlock allowed : No" <= this means you can't use UBL ROMs or custom kernels.
You can always root and use LBL ROMs though. There are plenty of LBL ROMs out there to try.
You can always un-root your phone. And you can always repair your phone's OS by flashing the Stock ROM via flashtool. Doing so would remove root access as well, no one would know you ever rooted.
Root using towelroot.
Get recoveries by Dssmex.
Then flash LBL ROMs, mods, ports etc. that you want.
and Be careful when you flash anything,
Read the threads, don't try to flash any UBL ROM as it may brick your device.
First thank you for helping.
UBL is unlocked boot loader right? and L is locked. sorry to doubt your last tip but i need to double check was it typo or...? you said don't flash UBL. isnt that supposed to say don't flash LBL. or i have totally got this wrong. maybe i don't know what what's LBL and UBL.
but just to be safe? where can i find stock ROM? i tried official site, they don't let me download firmware manualy. only trough sony PC companion automatic repiar. Which is ok too i guess. else i can download sony flash tool callsed emma, but i cannot get login info since they need about 7 days to approve my registration.
so my first step is to root my phone. ok i will do that. i might do it manualy, not trough application though.
what about sim lock? after i root phone, is there sim unlock command or what? and do i need code...how do you unlock your phone to be able to use other SIM.

Welcome.
And no, I did mean "Don't flash UBL ROMs"
UBL = Unlocked Bootloader
LBL = Locked Bootloader
The ROMs that are made for Unlocked Bootloaders are UBL ROMs.
Unlocked Bootloader users can use both LBL and UBL ROMs.
But since your device's Bootloader cannot be unlocked, you can only use LBL ROMs.
It's written in almost all ROM threads if it's a LBL or an UBL ROM. But if it isn't specified, then be sure it's UBL. (Like all 5.1 ROMs are for UBL)
Download stock ftf from here.
Use Flashtool v0.9.18.5
and I can't say about the last one as I don't use a carrier locked device.
Try and see what happens.
thank you again for reply. you've been very helpfull with all info.

that is exactly from where i got it the first time. also same flashtool version. after i tried to use that firmware, my phone bricked.
even though it's stock ROM, probably cause my phone had locked bootloader (i finally found article on what is bootloader and i got it now).
but after this, i have used sony software to recover my phone and it works again.
now important stuff. so my device's bootloader cannot be unlocked. does that 100% means that i'm stuck with locked bootloader and no way of getting it unlocked.
even on sony offical site there is process tutorial how to unlock bootloader, and it says "if you device isn't listed, than you cannot unlock bootloader".
but it IS listed and I AM able to get the unlock code for it. now i'm confused. can i still do the process showed?
another confusing thing is where i read about bootloader, it says that for to be able to root i need to flash custom ROM, and to do that i need to unlock bootloader.
but you have provided link for "towelroot" which was able to get my phone root acces. is it different from rooting my phone manualy after unlocking bootloader. how did it manage to root it anyway? and with towelroot it still has bootloader locked. actually it says "boot loader unlock allowed: NO!". now begs the question does that mean, not allowed, but i can be unobidient one and still unlock it without clearance, or does it mean .."you're stuck with locked bootloader. deal with it!. if you try to unlock bootloader your phone will brick"!.
i think after i get answer to this, than it would be my last question for this topic
also again, thank you for answering all previous questions...and this one, hopefully

Did you install the drivers properly (Flashmode, fastboot, viskan common) ?
You need to disable driver signature verification before installing drivers if you're on Win 8/8.1/probably 10 too.
And flashtool should work perfectly in both LBL and UBL phones.
You said your service menu says, "Bootloader unlock allowed : No"
Even if you get a BL unlock code you can't unlock it coz it's not allowed.
And by messing with the bootloader or trying to flash UBL ROMs may permanently brick your phone.
And different phones have different rooting processses. Rooting our SP is easier than most other phones by TowelRoot.
And "Bootloader unlock allowed : No" is more like a "You're stuck with locked bootloader. deal with it!. If you try to unlock bootloader your phone will brick!".
And you can still use a lot of LBL ROMs, from 4.3 to 5.0. So don't worry Lol.
Welcome
i did install fastboot and drivers and everything acording to tutorial. i payed attention on par "pay attention to this. be sure to install drivers correctly, lol"
i'm using win 7 64bit sp1. i have disabled UAC. i'm alaways running as admin. as for flashtool. software works perfectly..it just fail flashing.
it goes to part where i need to unplug phone and plug in holding volume something button..it says on poppup. than i plug in phone and it starts flasshing..it goes up to 40% something percent. if finish few files but when it comes to system.(something) i forgot extension, it says failed. flasshing stopped. than after that i can't turn on phone again.
i couldn't untill i recovered via Sony PC companion. i did try to flash it several times with several roms. i think it's cause my provider messed with bootloader. they locked it together with sim. on official sony site. it says:
"Note! Even if your device is listed here, certain releases of the device model may not be supported due to operator restrictions. Please select your device on the Start tab to check if your particular device can be unlocked."
anyway, i even got my provider's firmware trough flashtool download system, got my provider's name and exact same firmware that was installed. it still failed on same file.
than after i recovered i didn't try to flash anymore. i don't even know what's the point, if i can have root access without it.
i'm not so keen on installing other android version, unless this one gives me problem. for that i need to unlcok phone first to be able to even use it or test it so far it's has been t urned off most of the time

I see.. I'm not actually sure why Flashtool isn't working.
Anyways some good 4.4.4 LBL ROMs are 'CM11 by Bagyusz', 'Omni-X by NeildownX', PA etc.
Try them if you want.

I assume you're now on a rooted stock ROM.
Follow this to get recoveries.
Reboot, when you see the Blue LED burn, press vol down to enter TWRP recovery.
can i use cm-11-20150822-UNOFFICIAL with flashtool so i avoid installing recoveris or CWMP?
flashtool worked for me it just gave me an error during flashing one of the files....that might be cause i didn't know difference between LBL roms and UBL roms. maybe problem was incorrect rom type for my phone.
i tried to install recovery tools. and i had some problems...when i swhitched on phone there was no light showdown,,just red led...and after phone entered safe mode. but not in recovery menu.
i sure have no idea what to do...now everything is so strange.
to be honest i'm considering dropping this whole thig of and use stock rom as it is...
it would be cool if there would be automatic debloat application which will remove all bloatware...
or at least bloatware list of apps i can delete manually, without loosing important function on my phone. than i would not need custom rom!

If you're on CM11 by Bagyusz, Open Terminal Emulator and enter the following codes,
su
./system/bin/recovery.sh
^ it will give you access to recovery when you see the red LED while booting.
If you decide to go back to stock, you can freeze/remove these apps.
I made the list when I was on stock. Take a backup before removing them just to be safe.

Cannot unlock bootloader

But not because I bricked my phone or something, but because the model of Xperia SP isn't found on the official Sony website.
This one: developer.sonymobile.com/unlockbootloader/
Am I doing something wrong?
Hey! I had the same problem. I needed to unlock bottloader again, but I didn't have a key from my previous attempt. So I just opened the "email confirmation" link, entered my email, recived a reply, and then everything according to the instruction of unlocking bootloader. It helped me somhow....
The XSP section for unlocking bootloader has beed deleted somehow by Sony
WTF!! I also noticed this right now...
Since I had a still locked device available - I simply tried the following:
- open http://developer.sonymobile.com/unlockbootloader/email-verification/
- entered my gmail.com address since by gmx.de / t-online.de accounts never ever received confirmation mails!!
- got mail with link to IMEI-verification site...
- entered IMEI from my still locked Xperia SP
- got unlock code
- successfully unlocked my Xperia SP with that unlock code !!!
I really don't know why Sony removed the device from the device selection :-S
I hope, I could help you....
SONY is doing glories again!
Anyway, even that our device is no longer in the list, do note that it can still be unlocked, if the SERVICES menu say so. Just choose any device in the list, and hit Continue. You will then be escorted to a page requesting your e-mail address. Just enter it and follow the instructions. Yes, it may sent you an e-mail about unlocking the "other phone" you chose earlier, but it is fine. When you enter your IMEI in the next page, it will return you the correct bootloader unlock key
Or, you may just directly use the link on above post

xperia z1 c6903 cant unlock bootloader

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.
