[Q] Z2 Tablet Bootloader - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Hi all,
I've been considering getting the Z2 Tablet, but (despite the current lack of major ROMs and development for it), the deal-breaker for me is having a tablet which can have the bootloader unlocked.
I wanted to ask if anyone has got/seen a Z2 Tablet which has the rooting status set to "no", or cannot unlock their bootloader? I only ask because I have the Xperia T which came SIM and Bootloader locked and I cannot install custom kernels on it and I want to be completely sure of the fact that there is no chance of this Tablet being permanently Bootloader locked.
Thanks!
Peace out,
-Galcactus.

Firstly, the tablet has only just come out in some areas and it still is not available in most of the world - and we only just got root over the weekend. So roms/development for it is right at the beginning - give it time.
As far as unlocking goes - they 'should' all be unlockable - but if you are buying from a carrier in some countries they might lock it down. I can't see why any wifi-only ones would not be unlockable and in fact I haven't heard of any not being unlockable (although as I said it is only just released so there aren't a lot out there yet)

Locked Bootloader

Does anyone have a list of know Mobile Carriers who do not lock the bootloader to no? I purchased a z2 tablet from EE and it is set to no and I want to be able to
root my device, but it seems a bit of the luck of the draw trying to get one which allows it.
thanks
anyone?

Bootloader locked on non branded ZU

Hi guys
I'm a Sony enthusiast and love the Xperia line up have had several Xperia phones actually, loved them all.But what grabbed me most is the sleek precision engineered Z ultra, fallen in love with it since day one, but never had the opportunity to get it due to many causes on top of them it's availability in my country and high initial price. I lately had the chance of getting a new one and it amazed me actually. What bothered me is that when I checked the configuration menu I found out that the Bootloader unlock statue is set to NO, which is a nightmare. What makes it worse is that I have no warranty as a friend of mine got it to me from Europe brand new and on the packaging there is no trace or name that would justify that it was purchased on contract from a carrier. So guys, is there anyway I can get the Bootloader unlocked ? and how can I get information on it's carrier ''providing it was sold on contract'' . I have seen many people with various Xperia devices who have a Bootloader unlock status:NO on contract free phones, and also,seen many cases of the Bootloader unlock status:NO and people still could unlock it the official way. Please light me up

[Q] GPE vs Unlock bootloader guaranteed (factory UL?)

I'm looking to buy a Z Ultra in order to better support my FM apps on the Xperia Z* line of phones and tablets.
I understand GPE is guaranteed to be bootloader unlockable, and can be had at Expansys new for US $350 now.
But there are more ROMs and other development for the non-GPE models. Someone was working on a tool to convert non-GPE ROMs to GPE, but that doesn't seem too fruitful so far I guess. Maybe in future... ?
The problem with non-GPE Z Ultras is that many are bootloaded locked, and it seems very difficult to guarantee any Ultra bought is bootloader unlockable.
There are slightly used Z Ultras on EBay here in Canada for about $280 US. Good price, and the ads say "Unlocked" (Factory not specified, so I'd guess aftermarket SIM unlocked) but I understand Canadian Rogers phones are BL locked, and probably Canada Bell phones too.
I'd think that "Factory Unlocked" (for SIM of course) would imply BL unlockable, but I read posts here and there throwing doubt on that.
Anyone know that "Factory SIM Unlocked" from Hong Kong for example are guaranteed BL unlocked ?
Otherwise, I guess I'll just go the GPE route.
Thanks !

Bell and rodgers ZUs are both bootloader locked, and I think some un the UK (t-mobile?) were as well. I would think that any others should be bootloader unlockable. My two (one from SG and the other may be from HK?) both were unlockable.

I was working on a tool, but as I dont have a GPe it was difficult and I gave up. I think the only real bug left was baseband related, so no radio.

I actually decided to go for a Z2 Tablet straight from Sony for now. Deal seemed good; equivalent of $440 US.
Should be BL unlockable buying direct.
Z Ultra may be in my future still.

[Q] Cracking unlock bootloader allowed : no to Yes.?

Hey,
I have recently bought an Xperia Z ultra, and when i was about to CM11 it, i found out that the boot loader unlock allowed is NO.
Now where is live, i brought the phone through and import shop. so the procedure to obtain a operator key and send to Sony is impossible.
I can access my fastboot, i have even rooted my phone, but i really want custom roms and kernels to be an option.
I know that the usual answer to this is that its impossible. But i would appreciate if we discuss it to progress on this as i have seen too many people with this issue and i think it needs a solution. I would request the admin/moderators to keep this thread alive.
Now does anyone know why is it impossible ? is it hardware or software ?
any directions or people that i can personally request to work on this ? any leads ? i am really desperate, i really cant afford to spend that much on a phone again.
is the Xposed Framework any possible solution for this ?
any ideas information is helpful......
There is no solution, or one being worked on that I know of. In one thread it has been asked and a very good hardware hacker said that even taking the back off and putting a Xperia into it's maintenance mode you cant unlock a BL for these locked devices.
Have a read of the hard brick thread for the details
there seems to be a way, just a thought.
Upon on reseaerch, i am finding out a Linux command called kexec seems to be favour here. Since it can bypass kernel and force a custom one...
Work in progress for z1 here http://forum.xda-developers.com/showthread.php?t=2462799
Just leaving this link for other users like me, who might be searching... And also requesting to post replies here to see how much demand we have for this issue..
sp has something going on too
Xperia sp seems to have been worked upon in this matter recently http://forum.xda-developers.com/showthread.php?t=2377972&page=7
kexec for ultra
Kexec for the ultra itself
http://forum.xda-developers.com/showthread.php?t=2615708&page=4
Are there any developers I can call out/plead to regarding this matter?? its really frustrating to have this much of a powerful device and not play with it. I miss CM.
unlocked bootloader if it says no
I had no idea that the sony z ultra had some units that couldn't be unlocked. why would sony do this, it says being able to unlock your bootloader is important to sony. They even gave me an unlocked code from their site. I bought an factory unlocked phone, so stupid that this one here can be unlocked and that one can't. so am I stuck with a locked bootloader now? I sold my Lg because of this crap now I am dealing with it again ****

It's your carrier that has locked it (Rogers, i'm guessing?). There are only a couple of carriers that locks down the bootloader, like Rogers, O2 (i think) and another one that we're aware of.
It was bought factory unlocked from store no carrier involved which makes it even more crazy. I guess I will sell this model and get different one. Does the gpe have this stupid restriction on its model. I really like the 6.4 inch screen and don't want to go down in size. I am already going to get the nexus 6 so I definitely want a z ultra also

It's shouldn't be locked. Only a couple of carriers locks the bootloader. The GPe's bootloader is unlockable.
@BrownDog99 type *#*#7378523#*#* and check if you haven't. I don't think I've seen a factory one they is bootloader locked. What model? And from where did you buy it?
Ya i tried that it says no bootloader unlock. I bought it from a used cell store in toronto. It has a factory unlocked sticker on it, with no carrier apps installed or anything. Maybe it was a carrier phone, weird it came factory unlocked and with no carrier apps installed. I rooted it and put a dual recovery for lb and of course installed xposed. No custom kernel for me I guess. Too bad. I think it is Rogers and Bell that lock down the bootloader. I am impressed with the speed of it for a 800 snapdragon.

AT&T won't allow bootloader to be unlocked

Can anyone explain why AT&T won’t allow Motorola to unlock the bootloader for the Moto E? I just picked one up for $50 from Walmart (it’s branded for Cricket - had it sim unlocked for $2.68). Thought I’d have a nice, cheap toy to play with but since the bootloader can’t be unlocked I can’t do much to it.
Any insight is appreciated.

And that's the reason it's locked.
The only way it can sell for $50 (or $10 on Cyber Monday for the Tracfone XT830C variant) is if the carrier subsidizes it--at those prices, they're selling at a loss. So they need a way to discourage people from buying it with no intention of actually using it on their service. And one way to do that is to lock down the bootloader. You can get it with no carrier SIM lock and no bootloader lock if you buy from Motorola, but you'll be paying the full price, without the benefit of the carrier's subsidy.
@ code65536
I understand the point you are trying to make but I disagree. The locked bootloader only prevents me from rooting it. I got the phone sim unlocked for $2 and my wife is using it on a different network. Hence, they took a loss selling it for $50 AND now they don’t even get my monthly business. The locked bootloader does not keep me on their network. If that is their reason, it is flawed logic and not doing what they intended. At this point, why prevent me (us) from unlocking the bootloader.

That's why I said a locked bootloader was only one of the means. Carrier SIM locking discourages use on another carrier (the Motos are easy to unlock but many other phones are harder), and bootloader locking discourages people who have no intention of using it on any carrier and just want a device for the hardware.
Obviously these are imperfect since I bought a XT830C with no intention of using it as a phone at all, but limited deterrent is better than zero deterrent for them. For example, Consumer Cellular offers a 2nd gen Moto G for a substantial discount from the vanilla XT1064. With an easy to defeat SIM and an unlocked bootloader, it's easy for people to just convert it to a regular XT1064, and everyone at SlickDeals who buys it is not planning to use it on CC. People would still do that if they can't remove CC's customizations, but not as many.
Also, bootloader locking protects Cricket's “features” like their crippled tethering. Again, not perfect since you can use a non-Cricket phone for that...
Anyway, I am not saying that I agree with this practice (I was hoping to do more with my XT830C, but can't). Just offering the “insight” that the first post asked for.

That has nothing to do with it. Bootloader unlocking isn't sim unlocking, so I don't see your point. In fact, they've failed (based on what you said), since I AM using it on a different carrier other than Cricket, since I was able to sim unlock it.
ATT is just making sure most of their phones get locked now. They likely want to force people to use their worthless software and preventing bricking phones. The only recent one that hasn't been shut down is the HTC m8 as far as I know.
edit: saw you're second post " bootloader locking discourages people who have no intention of using it on any carrier and just want a device for the hardware."
Still, bootloader locking only discourages small niche of people. You don't need to root to make this a useful $50 small tablet. I can't imagine that is the main thought that goes through their heads when they decide to lock it.
