I know that you know much about this. So if I could ask, how and for what exactly is the TA used, except drm keys?

Because I noticed that informations there are continuously updated. For example there is unlocking key (that one could be there from the factory), but also I noticed there is probably info about all firmwares I ever flashed. So it's updated with flashtool? And how is it resigned after updating? Or is it just an image using unknown file system and there is everything in separate files? So some of them are signed and some of them not signed (those updated)?

I would appreciate if you could answer some questions. I would only like to know more about this partition. Thank you.

Any news from DooMLord.

I'm stuck with the official firmware.
[Sony Xperia T, TL, TX, V] gregbradley:
Why are you stuck with official firmware?

There are plenty of stock based custom roms you can try
[Sony Xperia T, TL, TX, V] biboudidou:
All that i found are ICS.

You Know custom roms for XS based on stock JB rom?

This will help me :)
[Sony Xperia T, TL, TX, V] gregbradley:
You seem to be in the wrong forum.

This is for xperia T/TL/TX/V

For the xperia S look in the xperia S forum

edit

Took me 1 minute to find a JB stock based rom in the xperia S development section....and I have never looked on the xperia S threads before....maybe try the search button

search

Opening xperia's bootloader is a common objective :rolleyes:
[Sony Xperia T, TL, TX, V] gregbradley:
But he was asking about Xperia S roms....up till then he was OK, but xperia S roms should be in the xperia S thread.
[Sony Xperia T, TL, TX, V] brendan.crossmock:
No, I saw it. And based off your answer, I am not going to pay for the unlock. Instead, I pledge to donate my money to this cause. :good:

DooMLoRD is not planning on developing a bootloader unlock...

[Sony Xperia T, TL, TX, V] nikc0069:
Damn was holding out hope he was working on KEXEC, wanted an unlock for my XZ. Looks like it might be sale time.
[Sony Xperia T, TL, TX, V] Erica Law:
A question to fellow Singaporeans. Is your bootloader locked? What's your service provider? (SingTel, StarHub etc)

I've noticed that when I buy my phones from SingTel, all the bootloaders are unlocked. My friend buys it from M1 it's locked.
[Sony Xperia T, TL, TX, V] Sisqo:
No news on kexec? I think our locked bootloader has been forgoten
[Sony Xperia T, TL, TX, V] @non4:
[MENTION=2784807]DooMLoRD[/MENTION] is still working on a miniloader, he says there's a long way to go though
[Sony Xperia T, TL, TX, V] @non4:
What do you guys think? Should I try this? http://xdaforums.com/showthread.php?t=2340388
[Sony Xperia T, TL, TX, V] @non4:
Been doing a bit of reading, seems any device can get an unlock key?! The difference on getting the unlock is fastboot is disabled on devices with unlock allowed: NO

So in theory we just have to force the thing to go into fastboot somehow then we can use the official method, any ideas or has this been covered already?
[Sony Xperia T, TL, TX, V] Sisqo:
Yes sony gives key even though bootloader cannot be unlocked. We know that we cannot enter fastboot, if there were a way to 'force' it to go into fastboot it would have been shared a long time ago:)
[Sony Xperia T, TL, TX, V] nikc0069:
You can enter fastboot - you can confirm that by trying the command to get the java version. It is the specific "oem unlock" command that is unavailable. If we could replace fastboot that would work but I think that would cause things to fail the hash check the bootloader does.

Kexec or similar is much more likely but I don't know enough about it to build a working kexec module. Or build anything really ;)
[Sony Xperia T, TL, TX, V] @non4:
Haha same or I would be trying. Hmm how would one go about replacing fastboot? Because if nobody has tried, who knows? Worst case scenario signature error blah blah reflash ftf blah blah blah :P
[Sony Xperia T, TL, TX, V] nikc0069:
I think worst case is brick. I'm not an expert but just an enthusiast, however I believe this is likely part of the 3 level checks that the bootloader does - checking hashes of the previous stage at each further stage. If the hash for fastboot didn't match then it would refuse to boot and brick (I think).

Don't quote me on any of this though - [MENTION=4322181]Tungstwenty[/MENTION] is the guy to talk to he knows much more about this for all I know fastboot isn't part of this chain of trust.
[Sony Xperia T, TL, TX, V] mirhl:
The problem isn't fastboot. The thing that is changed is the different bootloader which doesn't accept sony unolcking key

If i'm not wrong.. it should instead accept your operator unlocking key (which could or couldn't be revelaed to you)
[Sony Xperia T, TL, TX, V] @non4:
That's why I don't understand locked bootloaders, they cause more bricks than they can prevent! :mad:
[Sony Xperia T, TL, TX, V] nikc0069:
Haha only if you try and unlock them without consent ;)

I'd love to see a TA backup with full dump of the same handset before and after an unlock that isn't allowed.

Or indeed, the same from our Spanish friends who have had Movistar send this back to Sony to enable bootloader unlock. But then again, I wouldn't know what to do with it - I'm sure someone would though.

Interestingly I read that the bootloader unlockability is disabled when the carriers request it to be sim locked. This is why Movistar will help you get it changed with Sony - they didn't realise this. Unfortunately a sim UNlock doesn't do anything to change things the other way round!

---------- Post added at 02:54 PM ---------- Previous post was at 02:48 PM ----------

By operator unlocking key do you mean sim unlock code? As that is totally different. If you could use your sim unlock code to unlock bootloader that would be lovely, but I don't think it works.

I thought it was fastboot that simply had the oemunlock command locked out - which is why the Movistar handsets all had to be returned to Sony - they needed to testpoint and reseal the units for water resistance I suspect.
[Sony Xperia T, TL, TX, V] Sisqo:
how do you enter fastboot even though your bootloader isn't unlockable? you guys said you can, i've tried adb reboot fastboot and holding volume up, volume down, nothing.. so how?
[Sony Xperia T, TL, TX, V] Georges2251:
Why would you enter fastboot if it's unlockable?

Anyway, you can by using flashtool:

After installing, open the driver folder and install the fastboot and flashmode driver (last 2 on the list)

Then connect your phone (it's still on as normal)

After, you press the thunder icon, and then the fastboot mode option. Click Reboot into fastboot mode (via ADB)

Wait, the main log will confirm the mode, and the LED will blink blue.
[Sony Xperia T, TL, TX, V] Sisqo:
I said it is not unlockable. I want to enter fastboot to test something.. Tried adb reboot fastboot and also clicked reboot in fastboot mode in flashtool, the phone reboots, stays for 5 seconds in black screen and then boots normaly, and you guys said you can enter fastboot even though bootloader is not unlockable. So how?
[Sony Xperia T, TL, TX, V] gregbradley:
You do not need to unlock the bootloader to use fastboot commands. You can use fastboot and flash stock kernels with a locked bootloader.

The bootloader needs to be unlocked to be able to flash kernels without sonys signature.
[Sony Xperia T, TL, TX, V] Sisqo:
yes i know that greg, but how can i enter fastboot? pressing volume up when inserting the usb cable doesn't work, and all other methods i tried don't work.
[Sony Xperia T, TL, TX, V] gregbradley:
Have you installed fastboot drivers etc on your pc?
[Sony Xperia T, TL, TX, V] Sisqo:
doesn't ask for drivers when pressing volume up and plugging in the usb cable, only shows SONY and then the charging battery, and then black screen. but i have the latest drivers installed from google and also installed the fastboot drivers from flashtool.
[Sony Xperia T, TL, TX, V] gregbradley:
have you installed this

http://xdaforums.com/showpost.php?p=42541074&postcount=614
[Sony Xperia T, TL, TX, V] Sisqo:
did it now, but in installs adb.exe and fastboot.exe in program files. i have those in sdk/platform-tools..
[Sony Xperia T, TL, TX, V] gregbradley:
you can install them anywhere, just as long as you have them.

Have you set java in your environment path?
[Sony Xperia T, TL, TX, V] mirhl:
AFAIK adb command for fastboot is

adb reboot bootloader
[Sony Xperia T, TL, TX, V] Sisqo:
yes, tried that also, and all possible methods that i found, still no luck. i have lt30a, was on .142 with lt30p kernel, reverted to my stock lt30a .140, still cannot. tried on 2 pcs, one with windows 8 and other with vista. maybe making a full flash of ftf will let me enter fastboot?
[Sony Xperia T, TL, TX, V] mirhl:
You need to open device manager

Then, as soon as s1 fastboot is displayed double click on it and press update driver

If you did this correctly next time you go in fastboot mode it will stick
[Sony Xperia T, TL, TX, V] Sisqo:
i know i should search for s1 fastboot and update it in device manager, but it doesn't show.

volume down and inserting usb cable enters fine in flashmode.

volume up only shows sony and then charing, i've tried 100 times:)

pressing 'reboot into fastboot mode' in flashtool only reboots normaly.

adb driver is installed, i can do adb commands. just flashed ftf .141, i tought a clean install maybe would do it, but still nothing...
[Sony Xperia T, TL, TX, V] nikc0069:
Afraid I can't help much - just pressing the corresponding XZ volume button whilst plugging in the USB cable with the phone off. I did enabled unsigned drivers in Windows 8, installed the driver pack from Flashtool, and it picked up the correct S1 driver automagically.
[Sony Xperia T, TL, TX, V] Sisqo:
i've read that in several pages, also did that in windows 8 booted with unsigned drivers, not notification whatsoever about the s1 driver, nothing happens when pressing volume up and plugging the usb cable, just goes to charging.

thanks anyway for all your answers, i thought that because the bootloader is not unlockable i cannot enter fastboot... on other devices i would enter fastboot easily... damn sony:)
[Sony Xperia T, TL, TX, V] redincali:
Have u tried volume down then plug in the usb? Last time I flashed an ftf, I believe thats what I did. Volume up didn't work, only worked for entering recovery

[Sony Xperia T, TL, TX, V] Sisqo:
As said before, volume down works, and it enters in flashmode, not fastboot mode.

I pledge $40 US.

Would love to get this BL unlocked so I can bust out the DooMKernel
[Sony Xperia T, TL, TX, V] nikc0069:
Me too, but tbh I don't think anyone is looking at it. If you want unlockable bootloader best to sell up and buy a sim free device.
[Sony Xperia T, TL, TX, V] dully79:
That's my plan, probably won't get a T again though if I do.
[Sony Xperia T, TL, TX, V] LegibleEel:
Same, I'm waiting for the next Sony flagship Honami. Its a shame the XT didn't get much attention despite it being a flagship and the bond phone...
[Sony Xperia T, TL, TX, V] dully79:
I think I'll get a nexus. Sony release too many flagship phones. The S quickly followed by the T, which was quickly followed by the Z.

Sony easily produce the best looking phones, but I prefer practicality over cosmetics... and an unlocked bootloader.:D
[Sony Xperia T, TL, TX, V] mirhl:
Just buy your phone sim-free and at 95% you'll get an unlocked bootloader

You could discover that 2/3 years long contracts aren't so much convenient
[Sony Xperia T, TL, TX, V] dully79:
It was bought SIM free.
[Sony Xperia T, TL, TX, V] mirhl:
:/

And you can't unlock it? This is weird
[Sony Xperia T, TL, TX, V] dully79:
First T was Carrier and boot locked. Had it changed to SIM free and that's boot locked.

[Sony Xperia T, TL, TX, V] jcase:
The vulnerability doesn't belong to the Xperia community, it was not first used on the Xperia. I don't see you pointing at the origin of it either.

I was posting to point out what it was, because he did not identify what it was when it was already known. He isn't familiar with the Android community here, and it really isn't that big of a deal. He didn't go to any lengths to hide what it was either, and he sure could have.

Source wasn't needed, he wrote the exploit from scratch and had no licensing needs to cover.
[Sony Xperia T, TL, TX, V] DooMLoRD:
Thanks for clearing that up... My mistake sorry... Btw I never said that this belonged to Xperia community, it belongs to the Linux community...
[Sony Xperia T, TL, TX, V] bolillo:
Hum i have the lastest version and it is rooted ^^
[Sony Xperia T, TL, TX, V] AndroidHoneyComb:
The Xperia TL has the att bloatware version, but you can just easily flash the latest version of .142 on the TL with no problem. Xperia T kernel also works fine. Just that if I flash a xperia t firmware I need to disclude the baseband so I can keep 4G lte
[Sony Xperia T, TL, TX, V] Galcactus:
I know this wouldn't solve the bootloader "cracking", but why not create a virtual machine inside the running instance of android and use that to run a ROM? The 1GB RAM should be enough to be able to do that, or if necessary I'm certain that we could just create a stripped down locked-bootloader compatible ROM that would be better suited to running a virtual version of android. Could this function as a work around? I'm guessing that the majority of users want to have custom ROMs and relatively few want an unlocked bootloader for the custom kernels and overclocking/undervolting etc.
[Sony Xperia T, TL, TX, V] mirhl:
You can already have custom rom with locked bootloader

The problem is (like you said) that you can't change kernel (and so the custom rom has to use stock sony kernel)

But this is not only important for "the few" that overclocks/undervolts

A custom kernel is essential for every AOSP and CM, and i wouldn't want a detuned rom...

And btw, have you ever tried to run a virtual machine on your computer?

You would understand that that is not the way...
[Sony Xperia T, TL, TX, V] Galcactus:
I meant ROMs like CM or PAC, Miui etc. Which is why I thought that a VM would be ideal for this kind of thing, the only real restrictions would be the ones we put on it. I have run many a VM on my computer. If you allocate the resources correctly and optimise the system enough then it can run pretty smoothly. Anyway, I still think it's worth looking into, even just to see if it runs and/or works...

[Sony Xperia T, TL, TX, V] nikc0069:
I don't think anyone is ever going to pick this up. I know nothing about Android dev or I'd work on kexec as I really like my Z. Thought the t-mobile launch may spur things on. But sadly i may just go back to the Nexus 4.
[Sony Xperia T, TL, TX, V] babylonbwoy:
I wonder if this money would be used to pay a good lawyer to get some help or his opinion.

Sorry for my english I'll try to explain my point of view about bl lock :

Carriers ask Sony for whatever reasons to lock the bootloader on contract phones because they say the mobile belong to the carrier until it is fully paid,

so once the contract ends and the device is totally paid it should become fully owned by the user and thus we can do absolutely what we want with it

(and this is even more true when the warranty ends as there is no risk for sony/carrier handling repair for free), so they should give an unlock code to

everyone requesting it with proff of purchase or any other garantee of ownership.

Maybe it would sound dumb to some of you but I think that it would be a good step, even if we have the code only after one year it's better than nothing.

For example here in france carriers must give you (only if requested of course, greed as usual) the simlock code after three months of contract,

don't tell me it has nothing to do with BL I know that it's just an example of unlocking code given after some time).

If you want the simlock code before those three months you have to pay something like 70€, why not making something similar for bootloader ?

Just my two cent like you say in english ;)
[Sony Xperia T, TL, TX, V] abusedcloth:
Has anyone been able to just call AT&T and get the phone unlocked? Or is that not how it works? (And I'm talking possibly after the contract has ended)
[Sony Xperia T, TL, TX, V] LaZiODROID:
Not sure if this is what you mean, but a bootloader unlock is not the same as a carrier unlock. Bootloader unlock will allow the user to flash a custom kernel to the device (instead of using just the stock Sony kernel). Custom AOSP ROMs like CyanogenMod run on custom kernels so those of us whose phones do not allow a bootloader unlock cannot try them. There are some great stock-based ROMs here though, thankfully, so we're not completely losing out on getting some flexibility with our devices. (shout out to the devs!)
[Sony Xperia T, TL, TX, V] babylonbwoy:
I wasn't sure but after searching a little I found this on the portal (thread is here), about Xperia Play from Verizon which Sony added support for unlock bl one year+ after release.

edit : It would be better to find a legit way of doing it, fighting for personal rights must start somewhere...
[Sony Xperia T, TL, TX, V] nikc0069:
That wouldn't make a difference if unlock bootloader allowed=no. You just can't unlock it via official means without sending it to Sony.
[Sony Xperia T, TL, TX, V] babylonbwoy:
It was an example of Sony allowing locked devices to be unlocked later after release, XPlay Verizon was locked by the carrier is how I understand it.

If an exploit will be found to unlock not allowed devices I don't think the guy will give it free for the sake of community, greed is common even in so called android "community" they're all (well, would say most) about donations and money.
[Sony Xperia T, TL, TX, V] nikc0069:
I get that, and thanks for posting it. What I mean is - in the case of the XPlay Verizon, I don't believe the online/Sony portion of things allowed an unlock through an agreement with Verizon. However, int he case of these new devices, anyone can get the code form Sony - but it doesn't work on the actual device due to limitations imposed by Sony at carriers request. Movistar had to arrange for people to ship their XZs back (at least I believe it was the XZ) to Sony who then, at the behest of the carrier, unlocked the phones. If the bootloader unlock allowed=no, you have to send it to Sony, they can't enable anything from this end (otherwise I'm sure someone would have cracked this by now). I'm guessing on the new devices there is a hidden testpoint, or they reflash a partition but with their on signing keys or something so it passes hash checks.
[Sony Xperia T, TL, TX, V] gregbradley:
Test point is not hidden, we know where it is. It does not work because Sony closed the bypass that that method used (which worked on older phones) for our newer phones.
[Sony Xperia T, TL, TX, V] nikc0069:
Cool thanks :) I think the rest of the point stands though.

As I guess there hasn't been any progress on this I'm edging even closer to saying bye bye to the XZ. Back to Nexus probably.
[Sony Xperia T, TL, TX, V] dully79:
We should not be having a conversation about locked boot loaders.

In this day and age, we should be able to do what we see fit with our purchases.

I can understand carriers sim locking until your contract expires. But what do they gain from locking the boot loader?

You should be able to opt in or out at the expense of your warranty, and it should be as simple as that.

Obviously hardware failiure should still be covered but...

If you turn your £500 brand spanking new "Insert device here", into a throw/chew toy for your dog through incompetence tough ****, you should have bought a speak and spell.

Maybe if a petition was created and presented nicely to Sony highlighting the X Play history, they might consider doing something similar with other devices.

After all, they say they are developer friendly and locked boot loaders are anything but.:(
[Sony Xperia T, TL, TX, V] babylonbwoy:
Ok, it's not really important the way unlock is done, getting a code (didn't know that it's not possible this way) or going to service center or sending the device to sony is the same for me, as long as they agree to do it how it will be done doesn't matter.

Don't think that, everybody was thinking it's not possible to get DRM back once they're gone (even well known dev) until someone actually tried to backup/restore the partition, and guess what ? We can bring back DRM now with the Backup TA Tool... so who knows what the future has for us...

I only buy unlocked devices, just got a locked XT because I had the possibility to get a device with my contract and had no choice but getting a locked one, although we buy only unlocked mobile it's not a reason to not trying to find solutions for those who can't afford an unlocked mobile who are the majority of xperia owner I guess.
[Sony Xperia T, TL, TX, V] jewkhok:
has anyone researched any possible way to unlock it?

I was reading how Dan Rosenberg unlocked the moto boot loader in his blog has anyone any input in the possibility the same or similar procedure can be done with the xperia t boot loader?
[Sony Xperia T, TL, TX, V] matt4321:
It'll be useless as that requires access via fastboot and we don't have it. If we do, we can then use the official method. I have an unlock key for my device but can't enter fastboot
[Sony Xperia T, TL, TX, V] gregbradley:
You can enter fastboot and flash stock kernels with a locked bootloader.. It's not that which is the problem, it's the Sony signature that is needed
[Sony Xperia T, TL, TX, V] matt4321:
Ermmm you can't, I have a locked bootloader and cannot enter fastboot

EDIT: Do you mean flashmode?
[Sony Xperia T, TL, TX, V] oualidbenadid:
We can't get the sony signature on the custom kernels ?
[Sony Xperia T, TL, TX, V] abusedcloth:
Or customize the kernals already signed...
[Sony Xperia T, TL, TX, V] gregbradley:
We can do that but you lose the signature then

---------- Post added at 08:31 AM ---------- Previous post was at 08:29 AM ----------

No fastboot.

Before i unlocked my bootloader I could flash stock kernels.

You should be able to enter fastboot mode with a locked bootloader. But you can only flash packages signed by Sony. The unlocking process means you can flash packages without the signature.

If you cannot enter fastboot mode then it is probably not set up correctly on your computer....
