Service menu states i cannot Unlock my Bootloader :( - Sony Xperia Z Ultra

When in service menu it says
Root Status:
Bootloader unlock allowed: No
does this mean i cant ever unlock my Bootloader?
mean is it possible to still attempt with the unlock process and see if it will indeed hopefully unlock or am i out of luck?
i want to be able to install CWM Recovery so i can install a custom Rom...mostly a Stock ASOP Stock Android or GPE
at the moment i am on
Build Number: 14.2.A.0.290
Model Number: C6833
and i am not currently Rooted as it doesn't seem quite possible to Root Android 4.3 successfully
My device when i first received it was a branded o2 Carrier handset but days after receiving it the Network unlocked the handset for me as in Unlocked the handset to a Unbranded version so it will work on any Network...i dunno if this means anything to me getting the bootloader Unlocked

Sorry to say, but at the moment there is no way to unlock your BL
The best you can do is:
Downgrade to .532 (read my guide in the general section or you will lose cell reception/imei)
Root (follow LordManhatton's guide in general section)
Upgrade to a stock based rom (follow Jackie's rom thread or my instructions at #34 in that thread if not using his rom) - choices include:
DoggRom
[NUT]'s rom
Jackie099's Stock rom
monx®'s rom
StarFighter's rom

i searched for these but non of them seem to be stock android i like my stock lol cyanmod/gpe style

You will either have to live with it, or you'll have to sell it and buy a regular unlockable one. Not what you want to hear, but these things happen when carriers have a certain body part up their asses.

Dunno, but it's worth a try. I'm on O2 and mine has an unlocked bootloader. I would contact them and complain that it's locked and you want an unlocked version. I've done that in the past and since then I've always had unlocked versions.

Mine too. I just complained saying it wasn't stated anywhere that it was a locked bootloader and so they'd missold me the product. Works every time.

Getting latest firmware by editing build.prop

Hi Guys,
I was wondering if there is a way to get the latest gingerbread version by easily editing build.prop. I'm on Uk orange.
I remember doing this on my xperia x10 and I managed to change Uk version to Nordic version.
Unlocked handset from Orange
just using my old dead thread to ask a different question.
Will i get the gingerbread update if i unlock my handset originally bought from orange or will it still depends on when orange releases the update. I mean normal unlock by paying £5 and entering the unlock code on the phone and not the bootloader unlock

If you do a SIM unlock, you are still going to be waiting for the update from Orange whenever they release it because it's still their FW...

No. You need to root your phonem unlock your bootloader, flash new firmware. I'm on Ornage UK and you lose most of your RAM when unlocking the bootloader before you flash new firmware.

Yes you should consider it voided once you unlock bl.

A few basic questions

Don't currently own one, just want to make sure about a few things. Searched through the Dev forum but still I am not 100% sure and that's why I am asking here, just to confirm.
1. Is the bootloader unlocked for all firmware so I can flash custom ROMs or do I need to check something to determine if the bootloader is unlocked? I read somewhere that firmware 2.3.5 9 or above cannot be unlocked.
2. Does it come carrier unlocked by default to be used in countries other than the US, I mean use any GSM SIM?
3. What other phone can you tell me to look at, with similar specs and price range? I am interested in unlocked GSM, doesn't matter if its CDMA or not.

1) Need to be on 2.3.4 in order to unlock bootloader. If ordering from sprint, it might already come with 2.3.5. Buy from eBay and make sure to have the seller confirm its on 2.3.4.
2) Its a world phone. Its only carrier locked in the united states. But there are ways around this.
3) As far as used price range, the GS2 is probably the closest mainstream competitor on sprint. Galaxy nexus being just a bit more expensive. But you lack world phone capabilities and the photon is arguably a better phone all around depending on who you ask.

Thanks for that.
So if its 2.3.5, there's no way to unlock it? Something like Torpedo or 1 click unlock for Droid 3 would help?

Ok so it means that I cannot flash custom ROMs right? But I can gain root access to modify the OS installed.

2.3.5. locked means you have to use locked roms or the phone will fail to boot.

can you link me to something to read to understand what I can do/not do with root and what with unlock? I searched, got something but its quite confusing. What I understand is Root = admin access like but don't know about the unlock.
I think bootloader should be unlocked to install custom ROM but then there's something called fastboot which only requires Root. Confused here. BTW does Unlock means Unlocked Bootloader?
I want to know that if I have 2.3.5 can I install ICS or JB?

The rules are simple: You need to unlock the bootloader to install custom ROMs that use custom kernels. You can't unlock if you are on 2.3.5. You do not need to be unlocked to use custom ROMs that use STOCK kernels. We only have two ROMs that use stock kernels. The rest, including ICS and JB, use custom kernels so you need to be unlocked to use them.

[Q] Bootloader unlock on Sony Xperia S with ICS 6.1.A.0.453

Hello. I'm wondering if anyone's managed to unlock the bootloader on a Sony Xperia S / Firmware ICS 6.1.A.0.453 where in the service settings it says bootloader unlock not allowed on a locked phone? I've seen lots of guides on doing this with a phone with GB and early versions of ICS but no guides with the above firmware? Many thanks in advance.

You can't unlock bootloader if it's locked to carrier. Not even on a gb.
Ok Many thanks for that. So if I get the phone unlocked in the normal way from my carrier - will that also give me the option to unlock the bootloader as well? Many thanks again.

I think that it depends of your carrier.
Ok - many thanks again!
Ok my phone is now sim unlocked but its still bootloader locked and my carrier O2 do not support the unlocking of the bootloader. Is there any unofficial method I can use (even paid) to unlock the bootloader?
Yeah the O2 are the worst by that question,definitely.But try to make a pressure on them saying if it is not stated in the cobtract than they can **** themselves and unlock or you want your money back!

so the carriers are the ones who is holding back the bootloader lock?...
Yes,they are guilty!

I should have look into this a bit more before I got the phone. With any luck someone hill hack it soon!

Upgrade from MJ7?

Currently running MJ7 rooted with stock recovery (on boot it shows an unlocked lock with the word "Custom", which I don't believe means my bootloader is unlocked)
I've been waiting in the hopes that someone would find a solution for custom recovery, wondering if it's worth waiting on this build or if I should just allow the OTA to upgrade me

Nope. It doesn't mean your bootloader is unlocked at all.

They're very similar builds, the only downgrade you can actually do is MK2 to MJ7. So it doesn't matter which build you're on.

Confused about rooting.

Hi, sorry but I'm confused reading about rooting in regards to DRM keys, TA partitions and what method works with the latest firmware.
I've upgraded my firmware to the latest generic. 314 AU firmware and my phone came with the bootloader unlocked.
I want to root now and am confused as to whether I will
1.lose warranty
2.be able to restore to factory if I need to send it back for repairs
3.lose anything else
4.what method I need to use to get root with my firmware.
Thanks

Do you mean that your phone's bootloader is unlockable (i.e. can be unlocked if you wish) or do you mean that it has already been unlocked?
You'll lose warranty only if the bootloader has been unlocked. If you just root the phone (and keep the bootloader locked), then you still have your warranty.
You can restore to factory simply by using the repair function in PC Companion.
Root will not cause you to lose anything. But unlocking the bootloader will remove the DRM keys and TA partition.
Use the rootkitXperia tool to root your phone.
Sorry, I meant the bootloader is allowed to be unlocked, it isn't unlocked yet.
Do I even need to unlock it seeings as you can get root without unlocking it?

you do not need to unlock your bootloader for many things
-root
-recovery
-stock based roms
-mods
-root apps
-etc
flashing a custom kernel or non stock based rom requires you to unlock your bootloader, as flashing a kernel or non stock based custom rom will brick your device

Ahh ok. I essentially want root for a couple of mods and root apps as well as ad blocking.
So if I decide in the future to try a custom rom then I should unlock the bootloader before doing so?

Right. But before unlocking bootloader make sure to backup your TA partition so your DRM keys and other essential files needed for warranty is still intact. You can use TA Backup tool to unlock and re-lock BL.
Re-locking bootloader will bring back your warranty but once you unlock your bootloader and you did not back it up, you cannot bring back and you'll permanently loose warranty.

that doesnt make sense to me
it fails to boot, you can flash a kernel on a locked bootloader, the signature verifacation i do belive just doesnt like non existant or custom signatures
the result is a soft bricked device, its why i said it will brick your device, i may not have specified weather it was a soft or a hardbrick because both can happen from flashing a Rom or a Kernel to a device which its not ment for
im having trouble understanding you here?
my point being that you cant flash a Z2 rom or kernel to a Z1 and you cant flash a Z1 rom to a Z, cross-flashing isnt somethig to ever do

Sorry it's me who's got it wrong, I assumed by brick you'd meant hard brick and I'd misunderstood the issue with flashing kernel on bootloader locked devices.
So let's agree, Don't try and flash kernels or custom roms with custom kernels on locked bootloader devices.
