Hello guys,
I have read thru somethreads outside of our phone's forum, and found some people restoring TA's from phones that allow bootloader unlocking, and was thinking if it's safe to do the same with our XL.
I understand there are certain modifications that have to be done.
Thanks in Advanced!
P.S. Searched the forums of the XL, but I didn't find anything with this matter, sorry if it has bean brought up.
If you forgot to backup your TA like me see this thread

As stated above, yes it's possible.
But you don't get your DRM keys back, thus your warranty is still voided.

I must have expressed myself wrong.
I have my TA backup, but i have not unlocked my bootloader, because my unlocking status is NOT ALLOWED, yet my question is, if I can use a TA backup from another phone that has a bootloader unlock allowed: YES, so I can transfer this status to my device, therefor allowing me to unlock my bootloader.
Regards.

As far as I know its not possible to unlock your bootloader if unlocking is not allowed.
But you might want to take a look here. It's CWM for locked bootloaders.
If you really want to unlock you should consider selling your phone and buying a Xperia L where's unlocking allowed (mostly sim lock free phones)
There might be a risk of hard bricking of your phone if you restore someone else's TA backup

did u attempt? what was the result?
pls kindly let us know. if u conform....imtoo thinking for it.
Don't try messing with TA backup or you will end up bricking the device and i am talking about hardbrick. If you restore someone else TA backup your mobile won't boot up and you won't be able to flash FTF again.
Just got the D6633 dual Sim for my wife. I use Nexus devices exclusively but since Sony offers bootloader unlocking I decided to get this phone instead of a Nexus for her.
My question is, should I go through the steps to actually get the bootloader unlock code for future use. I don't plan on unlocking the bootloader just yet but I worry that in the future the service might be discontinued and I'll never get a code from Sony.
It's still under warranty and I'd like to keep it that way so I guess the real question is, is getting the code what voids the warranty or actually preforming the unlock that does it? Is there a counter or some type of a flag in the device that is set permanently or can the bootloader be locked back again like any Nexus device?
Thanks for your help.
No, it's not like KNOX [SAMSUNG] or S-ON [HTC]
Keep the code if you want.
That is one of the reasons I prefer SONY devices, besides the specs and build quality. No stuff like tripping KNOX fuse or getting S-OFF to make an HTC a Google Play Edition for example.
Keep the code, just in case.

OK, but if there is no tripped flag, how do they know I didn't use the code? I guess you didn't understand my initial question. I can understands the code doesn't expire, but doesn't the act of getting the code voids warranty?

You trigger something on their servers, it's all about the IMEI and Serial Number.
Even if you relock the bootloader, they will still know it was unlocked, I for example relocked the bootloader the official way, via SONY website, and got the code in my email.
Not quite. Warrenty is coded when you unlock the boot, nor when you ask for the code.
You can get the code and keep it forever.
Officially there is no way to re lock the bootloader anyway.
However, if you root first, backup the TA patition them unlock the boot, you can restore the TA partition to re lock and don't will not know.

True, it is a good idea to backup the TA partion, I myself didn't do it, but it is a good advice.
OK, so I'm gathering that there is a way to root and install recovery without unlocking the bootloader. If that's the case, why would anyone need to open the bootloader?
Also, I'm still not clear on my initial question. Do I loose warranty as soon as I get the unlock code from Sony or does the act of unlocking what voids it.

Only when you unlock you lose warranty. But you can backup the TA partition, and relock later, if you want.
With an unlock bootloader you can root Lollipop easy, with a lock bootloader, there are a few steps, like downgrading, for example.
And many more stuff you can do, with an unlocked bootloader, flash custom ROM's...mods, tweaks, etc.

So if you can lock it back and need to claim warranty they won't know you ever had it unlocked? Something seems not right.

If you restore your TA partition, yeah, you can claim warranty.
Hi guys. I need to know how to lock BL let you can't recognise it. Can you please hele me? I have D2403
If u relocking you bl then what is the point of unlocking of bootloader...
If u want unlock then u can unlock it by androcyda flashtool for xperia...
If u have your drm keys.. Backup then it ok.. U can restore them and get fully stock device if not.. Relocking will not do anything like that.
As far as I'm aware either re-lock via flashtool or by restoring the drm/ta keys which re-locks it. Unless you have the drm/ta keys pointless re-locking it to be honest as without the ta keys updates still won't work anyway not that we'll be getting Anymore updates should be a simple process either way though..
Hi.
I want to root my phone. I need ti unlock bootloader. Does unlocking bootloader break anything. I know on my z3 it messed the camera up.
Cheers for your help
Hi all.
I've got my XZ since one week now, and I'm missing the possibilities of rooting my device.
My Z2 was LB, so I never could ever try to unlock my bootloader. therefore, I don't know anything about it.
I've read a lot of thread here and there, and some points are not that clear to me.
Will the procedure of unlocking the bootloader erase everything in the phone (like photos, contacts, etc...)?
Unlocking the bootloader will kill the DRM keys forever, if I understood well. but flashing Androplus Kernel will recover them, right?
Is it possible to relock the booltloader after? if yes, will the DRM keys be restored?
Last thing, to be sure of what I should do.
1-unlock the bootloader with IMEI via sony site.
2-install TWRP via adb command
3-flash Androplus kernel.
Am I right, or do I miss something?
Thanks for your help, and sorry for the noobish questions.

Hey sensei_sai,
Im unsure if unlocking will erase your data but its always best to backup everything in the internal memory just in case something goes wrong.
Androplus will NOT recover your DRM keys but kernels with DRM fixes try to replicate the features that are permanently lost as a result of unlocking your boot-loader.
In the future it may be possible for you to re-lock the boot-loader but even then this wont restore DRM keys, the only way to restore DRM keys would be to back up your TA partition (This contains your DRM keys) before you unlock your boot-loader but to do this you need root access with your boot-loader still locked.
How to backup TA
Unfortunately at this time nobody has figured out a way to get root with a locked boot-loader although a newly found exploit (Dirty cow) may help us do this very soon so if you care about re-locking and keeping your DRM keys I advise waiting until a locked boot-loader root solution is around!

Thanks for your reply.
Too bad for the TA partition.
So we have two possibilities. Take the risk of loose some features forever, but benefit of the root or wait till someone make some magic to use an exploit to obtain root without unlocking the bootloader.
Risk and go... Or wait and safe... Dilemma...

I think that the era of DRM lock is over, we've been using DRM fixes for all the latest xperia phones, the dirty cow is a bad exploit and it's more dangerous than useful.
I was unsure about unlocking the bootloader but now that I did it, I rooted and I regret nothing, the only downside of unlocking is the warranty loss, but who cares as long as the phone doesn't magically explode.

OK, so did the bootloader unlock erase your data? Did you use the sony way or Flashtool?

Thank you, I've seen that guide, seems like it's not possible to unlock bootloader without factory reset.
