Locked bl - cm,aokp,pa,miui - Xperia Z Q&A, Help & Troubleshooting

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] s-off/ bootloader/ custom rom

Hello people.
Before i get a comment Like ''google it", i want to clarify that i think this thread will be useful to many people here. Why? Cuz i strongly beleive that many many galaxy users wont be grtting the gs4. No need to state the reasons.
Therefore, i bet many people, including me, are noob with htc devices and i would appreciate any help since rooting on gs3 was fairly easy compared to htc.
I know that with s-on i cant install custom roms , but i can still root it right? If i want to install a sense based ROM, do i need s-off? Or its only for aokp, cynogemod, etc?
For recovery mode, do i need s-off, bootloader unlocked? Or both?
Bootloader: does the international version comes unlocked?
Last question: who had htc one x or other previous 2012 htc devices, which ROM was more stabled? Batterywise? Speed?
Thanks in advance.
Sorry if any stupid questions made. But im rly noob.

With S-ON you CAN install custom ROMs AND root the device.
Only the UNRELEASED HTC DEV edition (only an US version has been announced so far) comes with an unlocked bootloader.

With S-Off you can flash the kernel through your phone alone(without relying on fastboot on PC). And you can downgrade hboot, basebands etc.
In short S-Off is a more deeper level of tweaking to a point that you could brick your device permanently. Bootloader unlocking is just... unlocks your bootloader. And the bootloader has the capability to mess with the kernel and system partition.
If you're using a Windows.
S-Off = Administrator privileges
Bootloader unlock = standard user
Locked bootloader = Guest user

Thx! That clears my doubts. Só with s-off i Can also flash custom ROM without PC?
Now I realize why ppl say sg3 is easier.

You can flash a kernel/boot.img without fastboot or a pc even if you are s-on. There is an updater-script mod to accomplish this.
S-Off = security check off. Meaning you can flash radios/fw etc that are not signed with HTCs private key.
Do we get updates rafter we unlock bootloader? If not - will simply locking the bootloader help to get updates?

No you will not get ota updates if you unlock the bootloader.
But I don't know what will happen if you re-lock it!

I will just try to buy the dev. Edition from US so I don't have to worry about unlocking lol.
My next step will be to learn how to root it and flash new ROMs

Sadly I won't be getting the dev edition since I'm not willing to pay $650 for a phone. Upgrading for $300 is a whole lot more appealing than paying $650. Hopefully someone will figure out how to unlock the bootloader for the AT&T locked version since obviously it won't be getting unlock through HTC Dev.

Why not? I saw at the blog that people could unlock from their website?
Also for me 650 is cheap. Do you know how much is an iPhone 5 64gb in my country? 1200 us dollar Lil.
You are luck to get a phone for only 300

Yeah I know some people got it worse. :/ but also a iPhone here for 64gb is 800 I believe. Still a big price gap between 800 and 1200 though.
The reason it won't be unlockable is because AT&T in the past had always had locked bootloaders that weren't unlock able byHTC Dev. I think the One X got it after a few months but I'd prefer not to wait. But for 300 vs 650 I can wait a bit. As long as it doesn't take like a year.

[Q] Successful Qualcomm MSM8960 bootloader unlock

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!

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

T-Mobile XZ is locked bootloader so u cannot unlock it.
cause in standard method of xperia unlocking u should get unlocking code from sony but they won't send it to C6606

I have already a custom recovery (I think its like in OMAP devices like Moto Dx2 or Razr XT910-912), so my question is if I can flash customs roms and if every rom on developers section is compatible...
So u can first flash custom boot loader and then try custom kernel and rom
But it s better to ask rom developer that u wanna install it

What?
1. There is no such thing as a "custom boot loader" for the Z.
2. Custom kernels will not run on a locked bootloader. Flashing one via recovery will soft brick the device.
To answer the original question, you should be able to flash any stock based custom rom on the C6606. I'm not sure on how it will affect LTE, but I've seen quite a few people around the forums using custom roms on the C6606.

Odd way to unlock bell xperia z or t-mobile xperia z bootloader?

Hey guys,
I own both the bell version of the xperia z, and the T-Mobile version. I ONLY want to use them as glorified tablets. Basically like the Ipod touch version of the iPhone, I want to use them unactivated. For me, its all about customibility and I really want to unlock the bootloader. I know neither of these can be unlocked, but in theory, if i wrote the software of the global unlockable versions (c6602/c6603) which DO allow for unlocked bootloader, would I be able to do it? I know signal would be screwy with the radios, but i dont care since thats irrelevant to me. Any help would be great, thanks guys.

Short answer: Never going to happen.
So its impossible to write c6602/3 software to it? Longer answer would be nice : P

Sorry, you can't unlock the bootloader if a device says: "bootloader unlock allowed: no" which is if you have a branded device. If you try it, you'd better throw it away.
If u can root everything is possible. As long as there's someone who provide geeky solutions
And under your situation u don't need flash different rom as there's a way to install recovery without unlocked bootloader in rooted phone.

hey, thanks a ton for the responses guys! So, is there ANY possible way I can get cyanogenmod installed on either my c6616 or c6606? (Bell and t-mobile)w
I don't have your phones so I cannot guaranty but you can try my method.
I got a c6603 from vodafone, and use ota to update to 4.3.
Since the 4.3 cannot root and I dont want unlock bl. so I use these steps
1. downgrade phone by flashtool to a version which can be rooted.
2. root
3. install recovery in locked BL:
http://forum.xda-developers.com/xpe...cked-bootloader-cwm-recovery-6-0-2-8-t2187363
4. Choose whatever rom you like and flash it.
DONE!
You cannot use custom kernels on a locked bootloader, so you cannot run CM, PA, AOSP etc.
Stock based roms only. There's no way around it.
Sent from my C6603 using Tapatalk
Awesome tips guys! Got recovery working and its all good- just ONE last thing:
are there any vanilla style roms out there like cyanogen that are stock based? I just want my pure android with some nice customizable features, no kernel updates or anything. Can you suggest any?

[Q] Locked Bootloader

Does this device have a locked bootloader like the Moto's of old where you cannot unlock it?
I'm talking about the International/UK device, Not a US version?
I was looking at ordering one as the Nexus 6 is way too big, but I want to be able to Root & Rom this sucker.

You can unlock it just fine. I did. Only some variants in the US doesn't allow unlocking.

Proceed with caution regarding expectations for custom ROM development for Moto X. I suspect that they will be few and far between.
