I assure you I cannot enter fastboot and others with NONUnlockable bootloaders will say the same. You were able to enter because yours was unlockable.
[Sony Xperia T, TL, TX, V] nikc0069:
This doesn't help unfortunately as the QFuse method isn't used on the Xperia's I don't believe.

Look for [MENTION=4322181]Tungstwenty[/MENTION] posts few pages (or a bit more) back, or Google about for them on the XZ forum. He outlines what can and can't be done atm, but basically the only hope unless Sony leak their signing keys is kexec. Doomlord is working on a mini-loader amongst other things but I don't believe it is a priority.
[Sony Xperia T, TL, TX, V] AndroidHoneyComb:
Locked and Unlocked bootloaders can access fastboot. The signed key is located in the trim area but that would tale forever and ever and ever to crack. A kernel will be checked if its signed unless its a unlocked BL.
[Sony Xperia T, TL, TX, V] matt4321:
I can't enter fastboot, 100% sure, been doing this for years. I'm on EE and in the UK so possibly has something to do with that. I can enter flashmode, not fastboot.

Locked but unlockable devices can. But nonunlockable devices I thought couldn't. I'm none unlockable and can't
[Sony Xperia T, TL, TX, V] dully79:
Same here. No fastboot on my bootloader locked Xperia speak and spell. :mad:

And before people reply i know how to fastboot, I have to fastboot images before flashing ROM's on my Xperia U.
[Sony Xperia T, TL, TX, V] gregbradley:
That's strange, there should be no reason why you can not enter fastboot with a locked bootloader... Maybe it has something to do with how they are preventing you to unlock...

I.e. Not that you cannot unlock, but that they ate preventing you entering fastboot which you need to do in order to unlock...
[Sony Xperia T, TL, TX, V] nikc0069:
I am locked to Three with a non-unlockable bootloader and I CAN fastboot - I can even send the unlock code, it just won't accept it.
[Sony Xperia T, TL, TX, V] matt4321:
Well this was an unexpected turn of events, some nonunlockable bootloaders can enter fastboot, and some can't. Did not know this
[Sony Xperia T, TL, TX, V] nikc0069:
But does it help with the bootloader unlock? ;)
[Sony Xperia T, TL, TX, V] matt4321:
Possibly for those that can enter fastboot but for me, dully and others who can't, unlikely
[Sony Xperia T, TL, TX, V] mirhl:
maybe you simply didn't install fastboot drivers..
[Sony Xperia T, TL, TX, V] matt4321:
Nope, I know how to fastboot. I assure everyone 100% I can't enter fastboot. It's EEs way of blocking unlocking I guess
[Sony Xperia T, TL, TX, V] dully79:
erm... thats not it. Otherwise i wouldnt be able to load up PAC ROM on my Xperia U

fastboot flash boot boot.img

fastboot reboot

flash zip

done

If i didnt have have the drivers the above wouldn't be possible.

The question is, does the device have fastboot disabled or removed?:confused: either way it blows.
[Sony Xperia T, TL, TX, V] matt4321:
[MENTION=2538774]dully79[/MENTION] are you on EE out of interest?
[Sony Xperia T, TL, TX, V] :
Just curious, what does the bootloader screen look like?
[Sony Xperia T, TL, TX, V] dully79:
No mate, TalkMobile/Vodafone. It was locked to O2.

I sim unlocked it after having an unholy war with the customer support team (bunch of monkeys) and then had to have it replaced under warranty.

The new device came carrier locked again, which i made them pay to unlock, but both have been bootloader locked.

carphone warehouse, phones 4 u, dial a phone and the others that sell multiple carrier contracts/sims dont have carrier locks, which means there is a good chance of them not having bootloader locks. Something to think bout when its time for a new phone.

---------- Post added at 03:37 PM ---------- Previous post was at 03:36 PM ----------

Dont know, but if yo do a search on how to unlock it youll probably find a youtube video that will show you.
[Sony Xperia T, TL, TX, V] matt4321:
Can't speak for this device but for other devices I've had its the same as the splash screen
[Sony Xperia T, TL, TX, V] peetr_:
Bootloader, fastboot and flashmode screens are just black screens. A little weird for dev friendly device.

No log, no feedback, nothing. Only LED.

And missing recovery patition was also unnecessary, I think.
[Sony Xperia T, TL, TX, V] mirhl:
i dont think that a "bootloader screen" exists

maybe you are referring to htc phones? sony's haven't this
[Sony Xperia T, TL, TX, V] :
Thanks for the info.

And yes I agree, in fact I'm not even sure why any OEM would omit the recovery partition.

Nexus, HTC, Samsung and ZTE devices all have something displayed on their respective bootloader/flash/download screens. It feels like Sony want to make it tricky to modify a phone (maybe that's a good thing?).
[Sony Xperia T, TL, TX, V] gregbradley:
All my contract Vodafone phones have come with the ability to unlock the bootloader and also SIM free
[Sony Xperia T, TL, TX, V] Knucklessg1:
Is Doomlord still actively working on this miniloader? Its been a couple of months since he first said we would begin.
[Sony Xperia T, TL, TX, V] nikc0069:
I believe [MENTION=2784807]DooMLoRD[/MENTION] said it was a project he works on when he doesn't have any other development work to do so progress is probably in stops and starts.
[Sony Xperia T, TL, TX, V] Galcactus:
I, personally, am still holding out for a surprise from Adam Outler, or zdzihu, maybe even binary. No system is 100% secure. But then again, I still think that the guys experimenting with the trim area were pretty close, even though their process and testing was very risky.
[Sony Xperia T, TL, TX, V] nikc0069:
Yea I did think Adam Outler or Dan Rosenberg may pick this up once the TMO version in the US was out. I did message both of them saying how much we'd appreciate, and pointing out the bounty. Let's hope!

Has either of them acknowledged the thread, bounty, or issue yet?

-Sony Xperia Z
[Sony Xperia T, TL, TX, V] nikc0069:
No they haven't. I'm not sure they will, but you never know. I've basically lost hope that the bootloader will be unlocked - as I said before, if I had the knowledge I'd do it, but I wouldn't know where to begin. If only Sony would leak their signing keys... it is a complex thing to do so can't see it causing issues with the carriers as once you start messing with kernels you take responsibility. Don't see why we can't just waive the warranty and get the bootloader unlocked if we want. Nexus 5 is out in October according to rumors - might move over to that once it is out... at least you KNOW you will get an unlocked bootloader with that... :)
[Sony Xperia T, TL, TX, V] dully79:
I'm waiting for the Nexus 5 now after the Moto X was a massive let down.

Word on the grapevine is Sony will make the Nexus 5 based of the Honami. Seems a good shout as the Nexus is usually the best device around at the time with some minor tweaks. Also, apparently Google dont wont to put the Moto X and the Nexus 5 in direct competition with one another.

It's middle of August so we'll soon find out.

[MENTION=4357847]mcsqwizzys98[/MENTION], did you get a wheel barrow to carry that beast around?;)
[Sony Xperia T, TL, TX, V] nikc0069:

Funnily enough I just got a call from Three, and , after trying to sell me something, they told me explicitly that they would transfer me to a department who could deal with a bootloader unlock. I specifically made sure that they weren't talking about a SIM unlock. Unsurprisingly, the call dropped on transfer....
[Sony Xperia T, TL, TX, V] Felix Ding:
Will donate $20+ if it works on Acro S (LT26 w), or someone can make CM10 for this phone (w/ locked bootloader).
[Sony Xperia T, TL, TX, V] babylonbwoy:
I'm not sure we should count on this. Very cool guys, respectful (I don't own any devices that Adam Outler works on but it's a pleasure to read thread where he explain how he got this or that unlocked/rooted).

The other day Adam Outler posted a picture of (what is believed to be) Honami on G+ and had to remove it the same day (meaning he is a Sony tester now), Also Sony is Elite Sponsor of XDA DevCon and looks like they have good relations with XDA giving all the praises on front page they recieve lately, so all this make me think that none of thses respectable XDA members won't do anything that go "against" Sony (well as long as they stay dev/xda friendly...).

Ah ah! The guy has a name : MC Hammer (U Can't Touch This video)

Edit : I don't believe that it will be achieved but I can give something like 20$ for my XT if I don't sell it before.
[Sony Xperia T, TL, TX, V] dully79:
His name is mc sqwizzy and he's touched it plenty;)

and locked bootloaders are not dev/XDA friendly.

It's a crock of **** how they are allowed to restrict our devices.

The majority of people on XDA should be here to extract every thing they can from their device, and that isnt possible with a locked bl.

If carriers are allowed to sell restricted bootloaders they should come with a disclaimer.

I would have told O2 to stick it if id known it was locked.

From now on im going instore and checking these things out in person rather than asking the dude over the phone.

Its like buying a house and finding out the door to the back garden is locked? I just want to play with my super soaker:(

Other water pistols are available.

Shame on Sony... or should that be Pony, as in Cockney rhyming slang; "pony-and-trap" - crap.
[Sony Xperia T, TL, TX, V] nikc0069:
I think if Adam Outler is now testing for Sony he is actually a very good person to leak some signing keys...
[Sony Xperia T, TL, TX, V] tesseraction:
I'll donate 20 Canadian if successful. Cheers
[Sony Xperia T, TL, TX, V] babylonbwoy:
Where did you read that ? U didn't understand.
[Sony Xperia T, TL, TX, V] nikc0069:
It doesn't really go against Sony. It goes against the carrier. The carrier who, in my case, doesn't train their support staff on bootloaders.
[Sony Xperia T, TL, TX, V] dully79:
Sony must be allowing it.

Sony must be providing the carrier with sources and keys in order for them to lock the bootloader.

If Sony didn't want the bootloader locked it wouldn't be locked. They couldn't give a monkeys as long as they get paid.
[Sony Xperia T, TL, TX, V] nikc0069:
I read somewhere they supply them unlocked but supply the carrier with the tools to lock the bootloader and simlock. If that is true it is definitely the carrier - but I admit it may not be correct information. Either way, this bounty isn't going to be collected. I'm living with stock based roms but would be nice to have the freedom to do what we like with phones we paid for.
[Sony Xperia T, TL, TX, V] dully79:
Exactly. it's not very developer friendly allowing carriers to lock bootloaders. They just care about the coin.

The funny thing is, the majority of Xperia users would look at you like just told them "The teapot milked the donkey":eek: if you mentioned a locked bootloader.

Why not leave the bootloader unlockable, because lets face it, most people dont know what the hell a bootloader is so they wont unlock it. They probably think you mean the dude who works in the shoe warehouse!

When i ask people if they have rooted their phone the usual answer is "what...you mean like put it in a plant pot and let it grow:confused:".

They should supply the code/key to allow the bootloader to be unlocked after a year or pay £50.
[Sony Xperia T, TL, TX, V] nikc0069:
Couldn't agree more with that last sentiment.
[Sony Xperia T, TL, TX, V] Knucklessg1:
Too bad Sony won't read this thread :(

-Sony Xperia Z
[Sony Xperia T, TL, TX, V] nikc0069:
Maybe just maybe they will mess up the bootloader security on one of the new handsets.
[Sony Xperia T, TL, TX, V] mirhl:
i think that no locked bootloader = carriers doesn't sell sony phones = more people who bought locked gs3/gs4

simply..

normal people doesn't care about this..

but at least power user (which want to change kernel) should know this things :\\

-Sony Xperia Z
[Sony Xperia T, TL, TX, V] nikc0069:
Good thinking. Sony may actually read it then! :) To clarify, I believe that when changing form 0 to 1, it breaks the hash on that partition which breaks the chain of trust/ multi-stage bootloader hash checks. What we really need I think is a TA dump (and preferably a dump of every partition) from one of those Movistar handsets from both before when unlocked was not allowed, and after when Sony have changed this, as it would provide further clues as to what changes. I am of course not a dev so don't quote me on that being useful ;) The miniloader would be great, but it isn't a priority for the knowledgeable devs.
[Sony Xperia T, TL, TX, V] MalithMax:
m running on a locked bootloader... sure... if itz gonna work i'll donate $10 ...
[Sony Xperia T, TL, TX, V] babylonbwoy:
Never said that "locked bootloaders are dev/XDA friendly".

And being friendly is not only about bootloaders, they provide tips and tool for building apps, they give and lend devices, they even gave 10 tablet Z for the Tablet Z competition, (lots of ?) money to sponsor conference and the android BBQ, and stuff that we are not aware of (preview, brown devices, etc).

THIS is what I was talking about. But you can still act like you didn't got me.
[Sony Xperia T, TL, TX, V] Knucklessg1:
Devs don't want to go against Sony's wishes of cracking Xperia Bootloaders after receiving so much support from them, basically.

-Sony Xperia Z
[Sony Xperia T, TL, TX, V] mirhl:
don't think too evilly

maybe it's only that sony bootloader is simple and very hard to break

some developers. already. studied. this (last link continues for 3 pages long)
[Sony Xperia T, TL, TX, V] nikc0069:
I think it is a combo of being very hard to break (no security mistakes like other manufacturers when implementing) and most people don't have a locked bootloader so devs aren't that interested in breaking it.
[Sony Xperia T, TL, TX, V] Knucklessg1:
So is this thread dead? No hope in unlocking Xperia Bootloaders then? :/

Read the last couple of pages of this thread:

http://xdaforums.com/showthread.php?t=2153261&page=51

This guys bootloader lock status magically changed when flashing a certain ftf. Not sure how and don't hold out much hope but if anyone wants to try it there is a link. I've not tried this precise ftf myself yet but have tried one that to all intents and purposes is the same.
[Sony Xperia T, TL, TX, V] gregbradley:
This had already been discussed and it does not provide any help, sorry
[Sony Xperia T, TL, TX, V] nikc0069:
I've given up and bought a Nexus 4.
[Sony Xperia T, TL, TX, V] jewkhok:
is there anyway?

Is it possible to log the process of an official unlocking and derive any information from that like official signature or anything?
[Sony Xperia T, TL, TX, V] nikc0069:
I don't believe so no. The official unlock wouldn't sign anything, just set something in the TA partition so that the bootloader knows not to check signing when flashing kernels. In a locked bootloader the oem unlock command isn't enabled so you can't set the process in motion to perform this change.

The best hope is still something like kexec, which I believe intentionally leads the kernel to a panic situation, and then loads a failsafe kernel-this process can be hijacked to load an unsigned kernel. This is the fabled mini loader as far as I understand.

TA backups have been discussed but changing them alters their hash and they then don't pass security checks.

Of course I was told a couple of posts back that apparently "we don't give a f***" if I got bored of explaining the fundamentals in a ton of threads despite the fact that all the info can be found earlier in this thread from [MENTION=4322181]Tungstwenty[/MENTION] who explains and understands it much better than I do. I've been on this forum since 2006 and this is the first time I've been directly sworn at.

the only way i can see is "a sort of" cracking key generation system, and understand how DRM, bootloader status and forced-locking work
[Sony Xperia T, TL, TX, V] jewkhok:
it actually does work

I had a phone call from O2 last week trying to sell me a new device. When i explained they had locked the bootloader (not the sim) and all the trouble i've had with customer services, they attempted to contact Sony on my behalf to see if it was possible to unlock the BL and was apparently told "not at this time". Does that mean they can and will unlock it, or is that just a generic line they spout?! Interesting.

Anyway, not something i need to worry about anymore. Shame as i really liked the T.:(

All had boot loader unlock allowed: Yes

I got my Xperia T home and well...... :eek:

They wont allow me to return it because I have "used the device"

Iv had this trouble with previous xperias I was hoping the old tricks would work (like flashing a relock ftf) but... no joy

I managed to brick this thing in less than 2 hours lol..... had to disassemble it to disconnect the battery.

I noticed 4 connectors that looked similar to test points.... they can be seen in this video.

I used the test point method on the xperia play seen here...

This is a 2 year contract I have with Three... it dosnt cost me anything to call customer services and I have sworn to phone them every day for the next 2 years about removing the bootloader lock.

Thanks a lot for the friendly explanation, I was just curious and the OP contains no info that suggests what

the problem is apart from the fact it's for the Xperia TL. I am a Samsung owner turned Sony and therefore

all the bootloader lark and complicated rooting processes are alien to me. Once again thanks for your kindness

and for being so considerate.
[Sony Xperia T, TL, TX, V] Knucklessg1:
No problem! I also am a Samsung owner turned Sony. I had a GS3 last.

So with Sony's bootloader, there is the ability to unlock your bootloader through Sony's official website, however, T-Mobile disabled the ability to unlock it officially. You can check to verify if yours is locked as well if you into your dialer settings and checking for "device unlock allowed = " "no" or "yes".

All the information I just told you was in the rest of this thread, so if you need more info, you know where to look. ;)
