[Q] Restore someone else's TA, to get bootloader unlock allowed: Yes - Sony Xperia L

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.

Bootloader unlock code for future use

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.

[Question][Request] Root for F8332 stock without unlocking BL?

Just as mentioned above. I dont mind waiting but just wanna ask is there anybody able to get it already? I've done some google, some pages offer a very 'detailed' instructions like just install TWRP using fastboot method then flash the SuperSU binary then bingo!! Some others state unlocking BL is required. Since to me xda is the only reliable source so I guess I will be looking for answers here.
Cheers
since the Z3+ and newer devices, root with lock bootloader is impossible at least for now.
btw, unlock bootloader is so easy for root, why not? Warranty?

Well... DRM keys thing is what i concern. AFAIK im gonna have to give up some features if i lose it so...
Btw it'd be appreciated if u could share some posts about re-locking bootloader and backing up/restoring DRM keys, especially for this new Xperia XZ.

I've been waiting for over 3mths for some progress on backing up the ta keys on all the x range(I have the xa) I don't see it ever happening to be honest and I've made the mistake of loosing ta keys before I won't be doing it again.

[noob question] unlocking the bootloader

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.

Is root without unlock possible?

I just wondered as a new Honor user wether root without unlocking the bootloader was possible, or if anyone is looking into to it at all?
Perhaps dirtycow or other ways?
Thanks in advance
I think that this is not currently possible. But the return of the original factory state is not a problem, see this topic here & here.
why do you even want to root without unlocking??whn unlocking is the easeier one than rooting...:good:

u should unlock but don't warry almost 90% of country's unlocking will not void warranty for huawei policies
Warranty issues and letting HW know that I've unlocked the bootloader.
Coming from Sony's previously you would lose DRM info for the camera and screen and audio tech if you unlocked without saving a TA partition.
Asume thats not the same with HW and its only a matter of them refusing to support you if you unlock?

Unlocked the BL without backing up TA Partition on my XA2 ULTRA..! Any suggestions ?

I know about the TA partition containing the DRM keys and backing it up from my previous XPERIA PHONES experience. However this time, I just unlocked the BL without thinking about TA backup :crying:. I tried to find some forums on it for XA2 ULTRA, but there is no specific well detailed thread on TA Partition backup for XA2 ULTRA. So what is the deal now? Have I lost my DRM keys + official SONY WARRANTY?:silly: Is there any workaround of restoring these DRM KEYS + TA partition? Shall I root first before doing so or anything else?
As far as I know, once you unlock the bootloader, they're gone and there's no way to get them back, but also you're not missing much, but you are definitely no longer in warranty.

But I also didn't find any forum pertaining to XA2 ULTRA's TA Partition backup before unlocking the BL. Anyways. I think if you flash the original ROM back again, the DRM keys are included in it. May be. I am not sure.

The ROM won't re-lock the bootloader, there's no way to re-lock the bootloader, and unlocking the bootloader is what scraps the DRM keys. Sony's site where you get the code for unlocking your bootloader using your IMEI makes it clear that it's permanant. I'm under the impression that the DRM keys are different for everyone's phone, so they won't be in the stock ROM that everyone can download and reflash.

Who gives the F anyways? I bought the phone from one country and will be taking it to another country, so there is not even a single point of reconsidering back the DRM keys + Sony's official Warranty. I hope this device would last 2 years without any problems.
