[Q] Xperia Z Bootloader?

Hey guys,
Just wondering if the Sony Xperia Z will come with a locked or unlocked bootloader?
if it is locked, can it easily be relocked after unlocking it for warranty purposes?
I know there isnt much info out right now, but i have never owned a sony xperia phone so,
someone shed some light for me?

Devices from carriers usually can't be unlocked. If you buy it outright then usually it can be unlocked. The process does not record your full IMEI and can be relocked after so you are pretty safe in that regard. My HTC takes the full IMEI (so it can be identified) and if you lock it then it goes to "re-locked" and not "unlocked" .... so the sony method is actually pretty good.
Before buying you can always check on a live unit if bootloader can be unlocked.

Ah okay thanks mate,

hmm new to Sony here too. So what are the chances of pre-orders from carriers being bootloader locked? Just to clarify, does that mean carrier purchased devices are useless (if they are locked)? I was planning to get my device from Orange Uk as i can get a pretty decent 40% off the monthly tariff which makes it the best deal for me. But if it is locked then I may need to pass on this....bummer

Well, if i recall correctly, the verizon droid DNA had a permanent locked bootloader too, but the guys here on XDA found a way to crack it.
who knows, maybe there will be a loophole discovered after the first few days?

I'm currently using a T-Mobile Xperia T, and the bootloader is not unlockable. So I would guess the same for the Z.
Though I think early units are generally unlocked (but don't quote me on that but this was the case with my Galaxy SIII and another guy mentioned this for UK network 3).

Is this just the way sony handles it's bootloader?
I unlocked several different phones which were ordered from a carrier without problem. Depends on the device itself!
But Sony seems to be very developer-friendly. There's a developer site on sonys website, where details about bootloaders are posted. Don't know the exact url atm, I'm at work...
For me it is essential to get a phone where bootloader can be unlocked. My first phone was a lg, without custom rom I would not use it anymore...

It all depends on the country. In The Netherlands all bootloaders can be unlocked, even if it are branded handsets from a carrier.

again as mentioned this is my first Sony Android device so please bare with me. Can someone explain the reasons to unlock the bootloader as from what i've seen people have said u still can flash ROMS with a locked bootloader?

If you're getting any sort of subsidy discount, it's highly likely your device will not be unlockable.
The general rule for Sonys is: If it is sold SIM-locked, you will not be able to unlock the bootloader. If it is sold SIM-unlocked, you'll be able to unlock the bootloader. If the carrier later gives you a SIM-unlock code for a device that is sold SIM-locked, your bootloader will remain locked (Sony is working on trying to change this with carriers).

Sony's bootloader security is pretty strong. If the Z were likely to have a loophole, the T would've probably been defeated by now.

You can cross-flash firmwares for other devices, but you cannot flash anything that has a modified kernel.

Thanks Entropy for your very helpful reply! I appreicate it
In regards to the discount, it is only because a friend works for them and in return are given a discount for friends and family. Otherwise it will be just the same as purchasing it direct from my carrier. My usual experience with purchasing a phone from a carrier, especially a newer phone which has 'just' (first batch usually) released is that they are usually simfree stock (sim unlocked), but heres hoping!

The Bell (Canada) Xperia ZL I have has an unlockable bootloader.

Only stok based roms... cm, miui, paranoid, etc bootloader must be unlocked so you can flash custom kernel
Sent from my LT26i

So therefore AOSP roms cannot run on a Locked bootloader due to requiring a different kernel. Where as variations/modded versions of Sony's rom can be flashed due to not requiring a custom kernel.
I think I understand now. The Sony rom looks decent to be honest which isn't something I can say about Touchwiz. It is actually skinned nicely and I wouldnt mind a de-bloated version of that.

I'm pretty sure sony will unlock it, judging from Sony's recent actions where they released the kernel source for the T if i'm not mistaken. Why wouldn't they do it for this monster phone right?

It's already listed on Sony's "Unlock Bootloader" site. So i guess they'll all unlock, unless you get it carrier branded/simlocked and they ( carrier ) will interfere with unlocking process.

I believe you need an unlocked bootloader to be able to boot the rom?
For htc devices, you need an unlocked bootloader, but it does not have to be S OFF.
If it was S ON, you just had to do an extra process of manual flashing the boot.img through fastboot

This is pretty simple if it's sim locked then it's also bootloader locked. The issue is not if you bought it on your carrier or on a retailer store. It's about locks

Depending on what you mean by "boot the rom" i am assuming you are referring to AOSP roms which use a different kernel to stock roms usually. Thus if you cannot flash a custom rom on the phone with a "locked" bootloader, you are stuck with stock Sony type roms. Don't mind it personally just sucks i cannot experience the great kernels that the XDA devs release. Fingers cross the first batch of pre orders will be unlocked though as they are usually sim unlocked in my experience.

50% true. As Entropy said the simlock can be "unlocked" by the carrier. This will therefore then be a sim unlocked device, but the bootloader remains locked. This needs to be clarified to Sony noobies like myself who may think sim unlocking will result in a unlocked bootloader, or by buying a sim unlocked device from say Ebay they have definately gotten a unlocked BL.

It's different again. With a locked bootloader you can't flash a custom kernel *at all*. I'm on a HOX now so I know all about the stupid htc bootloader unlock It basically means the device is useless for custom roms etc..
Still waiting to see if my local carrier will lock it or not, they have a mixed history with simlocking devices so could go either way. If it is locked I'll just pick get an iphone instead (should be roughly same price on contract) to sell on ebay and buy my sony outright I'll make it work one way or another.

Question Bootloader unlock

I've been away from Samsung a little while, the S21 Ultra has tempted me back.
Can't see myself not tripping them Knox for long, but does unlocking the bootloader alone cause this to trip? Thought id unlock this day one so I don't have to reset if/when the flashing starts. I will be getting an unlocked international Exynos variant.
From memory, factory images through Odin wont trip Knox?
Thanks!!

Largely it is way easier to unlock bootloaders on Global variants so the Exynos while not better per say it won't hold you back much and will give a better unlocking process as in the U.S. at least many Samsung devices get locked down.

I'm not too knowledgeable with this kind of stuff, but if you look at how Galaxy S8/S8+ root went, there was a bounty thread with a lot of money and in the end, no one was able to unlock the bootloader on the Snapdragon phones. It was way too hard, so everyone had to give up. They did figure out how to root the phone, but you had to use an old development version of the OS, battery was locked to 80%, and you couldn't install Magisk.

Answering your original question, unlocking the bootloader (either selecting OEM Unlock in Dev. Settings, and/or long pressing Vol+ on the DL screen, does *NOT* trip KNOX.
KNOX is tripped when you flash a customized boot.img file, not before

Yeh thanks bud, as I thought.

When you root and install custom kernel. It will trip knox. You can go for Samsung galaxy s21 ultra other country variant. USA version and Asian version (may be unlocked bootloader) are different. You can try custom recovery.

A71 SM-A715F/DS and A-716U questions

is the unlocked A-716U rootable using magisk and does anyone think there will be development on it(ie Custom recoveries ? One last question one this specific model; assuming root is possible on unlocked would it be possible to get a carrier locked version (cost saving) and reflash firmware similar to oneplus's MSMtool?
lastly is the A71 SM-A715F/DS root-able with TWRP support?
Thank you
ps
I will also contribute to bounties
everyone is going to say/think "search the forum!!!" but unfortunately the posts available dont list specific model numbers when talking about successful root/custom recovery,.

U.S. variants usually can't be unlocked and therefore you can't install custom stuff like magisk patched files.
That used to be the case until recently that a person was offering bootloader unlock as a service to many 2019 and onward devices, as you can see here: https://forum.xda-developers.com/t/sampwnd-usa-model-bl-unlock-info-u-u1-w.4201689/
But, you would have to ask if the A71 is supported. It probably would need to be tested, but the owner of the thread was quite confident that it could be possible.

Oh okay, so there is no MSMtool like with oneplus devices where you can just change to international firmware? If so if there an international 5g version of the a71 (any a-series) with 5G? sorry the model/SKU's for samsung devices is confusing and there is an insane amount of them.

I'm sort of guessing that's the Odin equivalent of Samsung devices, not sure I've never owned a OnePlus device.
You can use Odin to flash different firmware on the device as long as it's the same SoC. For example, I've flashed Galaxy S9+ Unlocked firmware on my T-Mobile Galaxy S9+. One is variant SM-G965U and the other is SM-G965U1. However on this case, both firmware were US. One was unbranded U.S. firmware and the other was T-mobile branded firmware. I've also flashed Poland firmware on my Mexican A71, they're both model SM-A715F on this case.
I don't know if there's an international variant of the A71 5G. I guess you'll have to look that part up on your own. I think there is though.

The MSM tool enable users to take a carrier locked oneplus device and unlock it among other things. can odin unlock bootloaders ?

Not really. Odin can only flash firmware, either stock or custom (you use it to flash TWRP and then basically everything else you flash with TWRP).
And no, Odin doesn't do any bootloader unlocking, any unlocking is done with the device itself. But as I mentioned, U.S devices aren't unlockable out the box.

There is no possible way to do it... for free as of now. If you want to unlock the U.S. variant you have to do it via the paid service I pointed out and thats only IF it works (as I mentioned, its been untested on the A71)
In comparison, you can buy the F variant, turn it on, head to developer settings and select OEM unlock and then unlock the bootloader.
If we ignore the paid service, sampwnd, that I pointed out in my other response then it is impossible to unlock the bootloader of the US variant and therefore, impossible to root.

No, and OnePlus seems to have no interest in updating its unlock token page since the 9 Pro. I have asked several times and no one in cust. service has any idea what's going on months after release of the NE2217.
I only bought the 10 Pro because I expected to be able to unlock the bootloader, as I did easily with the 8. At this point, I'm looking to sell the 10 Pro.

I upgraded from an unlocked 7 pro. I only got the T-Mobile version because they gave me too good of a deal to pass up. Honestly I'm pretty happy with it stock. There's not much you really need root for anymore unless you're developing. It was a big plus back in the day but not so much anymore.

Does anyone live in USA?, need favor.

it'll depend on when T-Mobile gives the ok. T-Mobile is subsidizing your phone so you need to play by their rules.

Honestly if a service provider is going to tamper with the device, just don't bother with them.
I'm in the UK but the crap I've seen people have with T-Mobile and Verizon is just insane, avoid them like the plague.
I think you'd be better off converting a Chinese phone and that's something I'd avoid more than sleeping on the opposite side of the bed to amber heard.
Go global, unless theres a fool proof way to make it to global.
EE in the UK did this on the Sony z1, I ended up bricking my device, so I sent it back via a third party retailer.
Original - EE.
Retailer - carphone warehouse.
They sent me an unlocked version, with a normal bootloader.
Not sure if that's an option for you. A little convaluted but certainly worked for me.

SM-G973u1 snapdragon root

Sorry to just drop a question, but I can't find the answer. Can the snapdragon S10 SM-G973u1 bootloader be unlocked? If not is there another way to root it?
Thank you
Chris

HelloChris333333, just when you post on a forum the courtesy of saying hello. Yes you can root just with the firmware of your model S10 SM-G973U1 US model so not compatible with EU firmware.

I'm not sure that's true, but I would love to find out I'm wrong.
In my research, the SD phones cannot be unlocked unless you are on (and remain on) an older BL version. The last unlockable BL version was 4, as I recall... if you're running updated firmware you are likely on BL 6. Even on 4, the process was not free and once you did it you could not update to a newer version of FW without losing the unlock.
For this reason, I gave up on getting root/BLunlock on my phone... and honestly, I have not missed it. This is also why I have not seen much development of FW for the SD phones anywhere.
Again, if I'm wrong, I'd love to learn how it's done!

Hello meric57
Can you share a link to the firmware I need? I just bought this phone and there is no OEM unlock option, it is a US phone. If I cannot root it I will have to sell it and get another phone.
Thanks
Chris

I guess another question would be where can I get a S10 with the Exynos chip?
Thanks
Chris

Using ADB I keep getting "waiting for device" and then I find I need to unlock the bootloader. This crap is an endless circle.

U4 can be unlocked before , I can unlock it , Special engineering documents need to be made

I'm V6 nothing available. I bought a G973F instead. G973u1 going on ebay.

Exactly, there is really no root/unlock for snapdragon phones unless you're on a very old BL (and you have to stay there so you can't update). IMO, that's not "can be unlocked" even with "special" steps, particularly since most phones today will have newer BLs (even a year ago, I couldn't find a BL4 phone)... but, yes, it's technically true to say it can be unlocked, but only in very limited cases.
@Chris33333 For this reason, I get that you may want to go to the Exynos instead... I'm curious, if you're in the US, how does that work with carriers? Does it? I've found most US carriers refuse to activate phones that don't match their list of "compatible" IMEIs... I imagine an F-series phone won't be on that list.

I'm in the US using Straight Talk with T-mobile. I've had a Galaxy S5 rooted for years. With straight talk I can use AT&T, T-mobile, or Verizon. But this international phone does not do Verizon.

And StraightTalk will activate the F-series phone without complaint or issues? If so, that's great to hear... because I know VZ and ATT typically won't...

I haven't put the SIM in it yet. Still trying to delete all the crap off the phone.

Lol
