Hello,
My Z3C has bootloader unlock allowed: no.
Is there any problem if I try to unlock it anyway?
Thanks!

No there is no problem, you probably won't be able to unlock it and that will be it.
Of course just remember that unlocking your bootloader will permanently disable some DRM-protected features.
The way around that is just to use the root exploit and backup the TA partition (good guide here).
If it say unlock allowed no, there is no way to unlock it so no point trying. But no trying won't do any harm, it's just pointless.
Some people were reporting that after sending in their phone for some hardware issues the phone they got back (the same one) had changed to booloader unlock allow yes. So this could be your last resort if you are lucky and willing to wait a bit it might work. Just make up some hardware issue like random crashes, rebooting or something.
And save your TA partition if you do that so maybe someone in this forum can spot the changes of before vs afterwards which would point in the direction what actually changes.

Why not get the key? It won't make any difference if you get the key or you unlock the BL without the key. Once you unlock the BL you will lose the DRM keys and BE2. Sony will be able to tell you unlocked the BL even if they don't have a record of you obtaining the unlock key.
Should've also posted this in the Q&A thread.

i see, so no way of leaving no traces that we have unlocked the bootloader before? i thought that they won't be able to know it if we didn't obtain the key from them
my main concern is the warranty, especially i've extended my warranty for an extra 2 years
p.s. can the mod please move it to the Q&A thread please? thanks

There's no way to hide it. Even if you manage to unlock the bootloader without the keys not having the DRM keys and BE2 is the proof that the BL was unlocked. Relocking it won't get the DRM keys back, they are gone for good.

Don't worry... They will not check for missing/present DRM keys, etc. So long as you flash to a stock ROM before sending it in, they will not even bother checking for unlocked bootloader.

the only reason i haven't unlocked my BL is the fear from voiding my warranty in case of something goes bad... (SOD etc.)

You should read this
http://unlockbootloader.sonymobile.com
They say, unlocking may void your warranty.
So their is a chance you can unlock without voiding it.
Just make sure you read there terms carefully before unlocking

You cannot be 100% sure about that. They MAY still check for DRM keys.

Yes but there's always a chance of voiding it. A chance that if the OP wants to take.
thanks guys for the feedback, will take it into consideration of the risk involved before i unlock my bootloader

o.k, so it's not a 100% safe I see.
is there any method (maybe in the future) of unlocking BL without loosing those keys?
afaik, since those keys are software-based and not hard-coded such as IMEI, perhaps there is a way to back them up to PC/SDCARD and 'regenerate' them once the unlocking process has finished?
I don't care of doing some research myself and share my conclusions here, can someone please provide a method of listing those DRM keys as a start point? I mean, SONY must has a way of regenerate those keys on unlocked BL devices if they want to, right?

At this stage no one has found a way to get the DRM keys back. Sony could get the keys back but they won't fix the device under warranty. My guess is that it's embedded in the BL somehow. And unlocking it somehow the keys are deleted. It could be specific keys as well (not 100% sure) for each device.

When you meant they wont fix the device under warantee.. That be after the DRM keys are redone and took as the repair is final. Or when sending it in for DRM recovery is also chargeable?
Go here http://forum.xda-developers.com/showthread.php?p=41763438 Backup TA partition and unlock bootloader. If you want DRM keys back, restore TA. This will also relock bootloader. It will appear as if bootloader was never unlocked.

Bootloader locked means u cannot load anything at boot that would tinker with the basic core of the device, like u cannot use custom kernels when ur bootloader is locked that is y ppl unlock their boot loaders Google for further info.
As for the OP's problem :
This is a known issue when u root ur device without unlocking bootloader, the solution to this is to do a full repair using Sony Suite which will result in loss of all data phone ,SD card etc .
check this link out its clearly stated over there
http://forum.xda-developers.com/showthread.php?t=2186368
Troubleshooting:
if your device has unlockable bootloader then after applying this hack the bootloader status will turn "Bootloader unlock allowed: No"
in that case dont worry the users have reported that doing a repair via SEUS will flash back stock firmware and turn this status to "Bootloader unlock allowed: Yes" (the same might also be achieved by flashing a stock FTF using FlashTool <yet to be confirmed>)
ROOT WILL BE LOST BY DOING THE ABOVE AND YOUR INTERNAL STORAGE MAY GET WIPED!
SO DO A BACKUP OF APPS & INTERNAL STORAGE ON AN EXTERNAL SDCARD/PC
How so some people can unlock the bootloader and some can't??

Hi. I'd like to know if there's any way I can relock my bootloader, after getting it unlocked, so that I can trick them and get my warranty back.
As far as I understand the unlocking and relocking procedure, they will still see that the fuses have been messed with. A relocked fuse value is not the same as the locked factory one.

If they just test the bootloader status with the secret code, they will probably see locked. If they do the same in oem-unlock mode, it will very likely be the same. But if they read odm_reserved, they see it has been messed with.
You should wait for somebody else to answer too. I don't own the device yet and do neither know about the internal workings of the lock status test app using the secret code nor the oem-unlock code checking mechanism. It could be possible that these also know about relocking and display that status instead of 'locked'.
It would also be good to know if there are any devices that come with relocked (i.e. next iteration checking fuses) bootloader [Bgby default[/B] from factory. If there was any, we could be sure that they won't notice that you unlocked and relocked.
ok, thanks for the help. I'll wait for more replies.
I'm trying to figure out exactly what you lose when you unlock Z3(C).
So far I've discovered that:
- Sony has a webpage that allows you to unlock your device
- Unlocking your device will void your warranty
- Unlocking is the only known way to get root (at least right now)
- Unlocking your device will kill the "TA partition" that contains DRM keys
- Loss of the aforementioned DRM keys will cause some stuff to stop working
I found a huge thread on backing up TA partition for older xperia devices, but no good information RE: what exactly you lose if you wipe out the DRM keys by unlocking.
Do any of you know definitively: what the DRM keys are for and what you lose?
As an aside - it looks like backing up TA partition is only possible before you unlock bootloader and if you've rooted your phone (so probably not possible on Z3C until someone finds a working exploit to get root with a locked bootloader).
Thanks in advance for any insights.
I don't think there is a definitive place which says exactly what you lose by unlocking the boot loader but judging by what people having been saying after unlocking the Z3C and other Xperia phones on 4.4 it seems like the answer is nothing. Nothing is lost on the software side at all.
On the z1c I neglected to back up the TA partition. And apparently lost native mirror cast and some camera features when I rolled the device back to stock.
Back up your TA partition before unlocking BL... If not for the I'm tact features turn for your warranty!
http://forum.xda-developers.com/showthread.php?t=2292598
Those that have rushed into unlocking the BL without backing up the TA partition risk voiding warranty I'm afraid.

Problem is, you need root to use those backup tools... So we would need a temp root exploit to backup before unlocking. But from what I've read so far, it doesn't seem like you lose that much, if anything.
I am also curious about this as I need root access but would like to preserve the warranty. Somebody else has also started a thread with what breaks with unlocking: http://forum.xda-developers.com/showthread.php?t=2890936

Most important consideration is your warranty such if your happy to lost it then unlock your BL.

It's not that definitive that you will lose warranty. Sony says it may void your warranty. Known issues with the specific model or batch, or other hardware problems that could not be caused by flashing custom ROMs/kernels will most likely still be covered.
http://www.phonearena.com/news/Sony...oader-unlock-tool-voids-your-warranty_id32972
I myself have sent in my Xperia T twice since unlocking the bootloader and on both occassions it was covered by the warranty.
Mind you, I did relock the bootloader and flash a stock FTF before doing that.
Flashtool has a function to relock the bootloader

I don't know if this works on our phone already, maybe someone who has already unlocked would like to try?

No, I don't think that is possible. I know that it was on a old Motorola devices, but not on Huaweis afaik.
It's both not possible.
If you rooted your phone you can't lock your bootloader and with unlocked bootloader you'll get this message. No way to remove or hide it, it's hardcoded.
On Huawei's sight you should be thankful for having an unlock code since they're not providing them anymore. So, write it down, safe it on a cloud, on PC, on Laptop, carve it in your wall and make a tattoo on you forehead, so that you'll never loose it.

It's not possible to lock your bootloader, or relock, with root.
You can only relock after removing the root completely. At the moment it seems that there's no possibility to completely lock the bootloader without downgrading back to Nougat.

Well, how many times a day do you restart your phone?
It's just a message for a few seconds, you should be more concerned about Huawei's ****ty update politics and the fact that they never will release 8.1 for P10 to fix issues with Bluetooth, NFC and other things. And you also should be more concerned about Huawei's unlock code strategy - they stop providing unlock codes for everyone.
So, the message is annoying but there are some issues produced by Huawei which are more serious.
BTW, this unlock message is present at all Android devices and there are no possibilities to disable this.
