[Q] Successful Qualcomm MSM8960 bootloader unlock - Sony Xperia T, TL, TX, V

There is a detailed writeup of a successful bootloader unlock of Motorola MSM8960 phones, exploiting a vulnerability in the Motorola TrustZone kernel:
http://blog.azimuthsecurity.com/2013/04/unlocking-motorola-bootloader.html
Since TrustZone appears to be an ARM / Qualcomm technology, would it be possible to use this same or similar exploit to unlock the bootloaders on the Sony Xperia T and V?

I don't know enough about boatloaders etc. To give an informed answer, but I would personally lean towards no because I am unaware of the Xperia devices using these software fuses. Furthermore, I'm relatively certain that the kernels will be different between Sony and Motorola devices. I'm not saying there's no chance of it working, but then again I'm not saying it will work either.
I'd be interested to hear what the devs have to say about this though.
Good find nonetheless!

Apparently, no devs are reading the Q&A forum...

Boot loader Unlock and SIM Unlock is controlled by .TA file, People like XperianPro have been trying to unlock the bootloader by flashing a .TA (could hard brick your device, 95% it wont work, 50 it will hard brick device, 100% it will disable radio ( cant call or text ). It worked for one guy
ONE DAY WE CAN UNLOCK ARE BOOTLOADER!

Motorola releasing bootloader unlock-tool

So it starts again, the bootloader issue..
Motorola has released a tool for unlocking the bootloader of certain devices. Milestone is not one of them yet.
Do you think Motorola will support the Milestone in the near future?
Or maybe this tool can somehow be exploited to unlock more Motorola devices? Any thoughts?
This is the thread about it.
No chance. I believe alsmost none from the existing lineup, especially those from 2011 and backwards (as our Milestone) will get their bootloader unlocked.
Motorola sucks in the development/openess department.
Since I got my Xperia Arc I can see what are the real pros of an unlocked bootloader.
If it wasn't for nadlabak (mainly) we would still have a FroYo (and a buggy one...) ROM flashed into our devices.
Milestone !? I don't think so.

[Nub Q] Unlocked Bootloader

For HTC phones I've always noticed that they release the dev. edition which comes with an unlocked bootloader and is therefor rootable. Then it must be true that the regular release comes with a locked bootloader, is there generally a fast update where someone finds a way to unlock it or is the best bet to just buy a dev edition?

In the US unlocking the bootloader from a phone you get from at&t etc. is not completely legal: .. that being the reason why they sell the htc one dev version there!
You can unlock the phone via htcdev though It's simple and officially from htc :victory:

WRONG. Please do not spread incorrect information.
Unlocking a bootloader on ANY DEVICE OR CARRIER in the USA is 100% LEGAL.

I remember reading somewhere that the HTC One X+ was given extra restrictions by AT&T so it was harder to unlock. Can you have a bootloader sent to a website/company to have it unlocked for a small fee?

No because if HTC dev is'nt avaliable to unlock bootloader than it's uasally xda folks that crack the bootloader and most xda folks share the unlock, plus if only some small company can crack the bootloader for a fee, the development would'nt be very good

Locked bl - cm,aokp,pa,miui

I've been using motorola defy before I bought my xz. The whole world knows about motorola and their bootloader policies. They arent customer friendly and now google has upper hand over motorola. The 2010 motorola devices like moto defy which I was using before is stuck with a locked bl. With the locked bootloader, we used 2ndboot, 2nd init and stuffs which exactly made us use custom kernels
Custom kernels with locked bls!!
So I feel its possible to use all the non stock roms with locked bl.
Link of cm10.2 for moto defy which uses 2nd init, 2nd boot with custom kernels

Any comments?

Just read the stickies. This is nothing like the Defy in terms of the bootloader regime.

There is nothing in the stickies about the discussion in this thread and defy has a locked bl, people are using cm,aokp on it.

Nope, unfortunately all carrier branded Xperias 2012 onwards are permanently bootloader locked. I'm not very familiar with the method you mentioned but I think I've heard of it before, sounds like kexec. To answer your questions, none of the devs here are willing to invest the amount of time it would take to be able to get a system like that working because they all have unlock-able devices as it is so they have no need for it
In short, as it stands non-unlockable bootloader, no custom kernel, no CM, AOKP, PA, MIUI. Sorry
I remember they unlocked the bootloader of the Xperia X10 backnin the day. I remember it was not that safe. One wrong flash and you could hard brick your device (did you brick your Defy that way). Unlike current official unlocking methods, today is very very hard to brick a device.

Its tuff to brick defy cos it has locked bl. Moto devices had efuse command on the bl that anyone tries to unlock it, hack it, mess with it or somethin, you hard brick it! And defy has fastboot locked or devs there are in a great doubt whether if its even there in that device.. the bl is very very strong.non unlockable...

There used to be 2nd boot , from there we can choose the boot methods like 2nd boot or 2nd init, and one thing..those devs are one rockin devs. Quarx and epsylon..they ve gone from eclair (2.1) to jb (4.3) !!. Patched hundreds in linux kernels and stuffs so that they can make it work..

All bootloader lock/unlock status with Xperia Z is tied up with TA partition. Any attempt to mess with it results in a hard-brick. Sorry guys

[Q] Any thoughts or news on an unlocked bootloader?

I know an exploit was shown at Blackhat 2014 in August but i also know there was some question as to weather the exploit would be released. Is there any news on that exploit being developed into a usable one for the masses? I am debating between updating to 4.4.4 or trying to hold out for longer for the exploit.
I updated and If I had to do it again I'd wait. None of the root options work and the new dialer is OK but not worth missing out on a chance to unlock the bootloader. Just my opinion.
Sent from my XT1058 using Tapatalk
It is being discussed at http://forum.xda-developers.com/moto-x/general/request-help-exploit-moto-x-bl-t2828471
We have no word on any developers working on making a tool or repeatable process based on the exploit for the masses to use.
So we have no idea when, or even IF, anything will come out.

Bootloader Unlockability and Source FIles

Any update or news on the bootloader unlockability and kernel source availability?
Motorola's site lists upto the Moto G6 Plus still.
the phone is not yet released atleast in India. I am planning to buy it though. And hoping to see good support

i don't think there will be unlocking with verification code like general moto phones. it will be probably be just going to fastboot mode,
then ' fastboot oem unlock', voila it's unlocked. android one phones have this very handy feature. i hope really good custom rom devs buy this device since motorola hasn't been that popular in the xda community these days. hope this one makes it better

Motorola has always been developer friendly. we'll probably have kernel source files in less than two weeks. they suck at updates but bootloader unlocking has certainly been easier on moto devices. In terms of nokia android one devices, it was nokia who made that choice. i said what i said because i was talking about a moto android one device not android one device per se .

This phone has got to have the slowest of development I've ever seen on a phone.
No custom roms or mod threads started yet.
