[Q] Restoring phone to stock - Xperia Z2 Q&A, Help & Troubleshooting

Hi everyone, wonder if you can point me in the right direction.
I'm currently on a custom rom with an unlocked bootloader and I wish to go back to stock including locking the bootloader, from what I've found out so far this is what I need to do: -
Flash original ftf
root
flash TA
reflash ftf to lose root
Now back to stock with "Bootloader Unlock Allowed: Yes"
Trouble is I can't find how to go about restoring the TA partition from my TA image so if anyone can explain what software I need and the steps I have to take I'd greatly appreciate it, thanks.

You can use the same tool that is used to backup the TA partition (read the FAQ in the 1st post):

I didn't know that you see as I used the Doomlord root exploit before the other methods were available, thanks again.
Edit: Thanks again, I'm now back to stock with the service page reporting "Bootloader Unlock Allowed: Yes"

Sorry for high-jacking this thread, it however loosely fits my problem.
When I got the Z2 I was, in all honesty quite quick with rooting and swapping the stock Sony ROM with Cyanogen. So quick in fact that I didn't bother for two seconds to actually perform a backup of the system beforehand.
So my question is this - is it possible (given the fact that DRM and such will be lost for all eternity) to revert to stock rom without the backup?
If so... How really? (couldn't find anyhone so stupid on here to do the same rookie misstake as I did so no answers was found while scouring through the forums...)
Thanks in advance, and yet again, sorry for high-jacking the thread.

you can revert to stock using flashtool and a ftf of your choice, also you can use flashtool to relock your bootloader
your drm keys wont come back
flashtool.net <flashtool im talking about

Thank you for a quick reply - forgot to add a question, what happens to the phone WITHOUT the DRM keys? What will I not be able to do - that i presently can with cyanogen or non-f***ed-up-stock-ROM?
Thanks!

nothing is affected by your drm keys weather they exist or not in 4.4.2/4.4.4 xperias they are simply used to check if you have modified your device ie. bootloader unlock (relocking doesnt restore your drm keys)

Ah, thank you!
Well as I already figured that I messed up any warranty, that's no issue for me, so really thank you. I was hoping that I could restore to original stock rom to be able to properly use the camera and noise-canceling headphones. Seems like it then. :good:

If you just want root access then just use gingerbreak, bootloader unlocking is not needed. Also trackid will no longer work if the bootloader is unlocked.

Make TA backup before unlocking bootloader. When you want to re-lock it, write original TA back.

You keep referring to "keeping a backup of your TA". Still, to the best of my knowledge, we have no tools for that yet :-O Unfortunately.

Yes, I constantly do that because that's the most important part of Sony Ericsson S1 phone. If everyone here had original TA backups before unlocking bootloader, there won't be any need for 16 pages of discussion on how to fix bricked Plays and still not find a 100% working solution.

Here's my thought:
We first need free TA backup and write.
Then someone with fully working play should make TA backup (Both a and i Play)
Then I find out the addresses of security zone in TA.
You backup security zone.
Write TA backed up from working phone.
Write your security zone.
That worked on every SE phone so far with GDFS/TA.
What is the TA you're referring to?
Trim Area - part of the phone which contains unique and important data like IMEI, Sim locks, radio data, etc...
Ah, I see. It seems a lot like the /efs folder in the Sammy Galaxy S.

Yes, something like that, only thing is that TA has signed parts so it's almost impossible to unlock phone for free at the moment.

[Q] Any way to change Bootloader unlock allowed: No?

I found only more than half year old info about this for Xperia Z2. Is at this time any possible way to change unlockable status to YES?
I flashed from my stock 4.4.2 Orange to new GLOBAL generic 23.0.1.A.0.167 4.4.4 RU ftf and i was hoping that the loader.sin contains bootloader data...
No, if the device isnt unlockable its imposible to change that
(close to imposible is more acurate)
I think you need to pay for it... I think!!!!

Is it sim free??? If so how about swapping it for my bootloader unlocked no drm so cant use remote play z2? lol
On another note, now that i dont want this particular Z2 anymore, has anybody actually tried flashing someone elses TA backup to the z2?
Im not asking what should happen if you flash a TA backup thats not from your phone, im aware of that....... therefore im assuming it hasnt actually been tried?
Sorry for the noob question,but mine says bootloader unlock allowed:yes,so does this mean I can unlock it if I want to or is it already unlocked?And Does it have something to do with DRM keys (I don't know what they are).I mean did I buy a phone that is already done some stuff with on it,or is it ok to see these expressions?I hope I could tell what I wanted to tell.

Flashing someone elses TA will brick your device, each DRM key is unique to the device and the code set is discarded after use

Yes, DoomLord, Championswimmer, other asorted Xperia veterans have shown this before, you can even ask doomlord him self and he will tell you the same thing i did.
I dont think its recoverable when you brick from a DRM mismatch

Its the exact same case with a Xperias Since Xperia X10
Every device showed the same results, after a few devices killed we just asumed they were all the same and seeing Since the TA partition and management hasnt changed its still not posible to flash a different TA to your device aside its own
At least in Spain IS possible. You only need the code to sim unlock and ask Sony to take your phone to a technical service and they will change it to allow unlocking bootloader.
I've already done that.
I know the question was asked million times but I'm quite desperate with my Xperia. I love the phone, it has good specs and never failed me. The only problem is unlockable bootloader and I'm bored with Existenz. I came across a thread on reddit where guy was able to unlock bootloader of his Z5c through the official way even though the service info said no. https://www.reddit.com/r/SonyXperia/comments/4gnc99/z5c_bootloader_unlocked_allowedno/
How likely is that? Is it worth trying? And if unlocking fails, will it brick my phone?

[SOLVED] Root Access 4.4.4

Hey guys im back after smashing my beloved xperia z (which i had mastered the ins and outs of) and reluctantly replacing it with a HTC ONE m7 which was the most terrible phone i have ever used in my life.... i have plonked a good bit of cash on a z2 and I AM LOVING IT
I had updated to the latest version of KK but i am hearing mixed reports that a root is not available for this version.
If anyone could point me in the right direction that would be fabulous.
Thank you in advance

Hello
I see you are totally green on this.
Well, im kinda green too, but I have had a lot of help from @xda and now I can manage to do some stuff with my telephone.
The first thing you have to do is BACKUP!!! This is always important.
Well, then lets get to it.
The XPERIA Z2 has a locked bootloader. This means that it cannot flash any roms, custom or other without being unlocked. When you unlock the bootloader, you delete all files on the phone, (don’t ask me how, it just does) and also deletes a partition called TA. The TA-partition contains DRM-keys, to explain that, @Envious_Data might help.
Anyway, when you have root, you can backup the TA, BEFORE you flash any custom ROM, or the ROM with ROOT. That way you will always be able to go back to scratch. Without ROOT on 4.4.4 you need to downgrade to 4.4.3, ROOT and backup the TA-partition before you even start thinking about unlocking bootloader.
(search the XDA, Google (use XDA in the end for XDA results) XDA-TV and you will find tons and tons of stuff. Once you understand some, it will come fast to you.)
I have gathered some threads here for you to read, and I hope this will work for you too.
Start off by reading this
When done, notify me.
All the best

Several problems with Xperia Z2 after unlocking bootloader

Hello XDA community,
I have a Xperia Z2, and i unlocked bootloader WITHOUT saving my DRM Keys, (i know shame on me :crying, now i know I did something stupid, nothing to do about it, but since i unlocked, i have had several problems: inestability, it means i am using an app and it restarts, or just closes, or even my phone restarts, if I go to contacts i dont have facebook contacts, the option just dissapeard, it means birthdays dont show in calendar, average camera photos just too noisy or awful photos, xreality not working properly, i know some issues are known but i havent heard about facebook contacts, to be honest i feel really bad with phone like it. So my questions are these, and thank u, thank u who could answer me, just work with me I know a little of these world, so if u could be a little specific about instructions or solutions i would really appreciate it:
1) Having an unlocked bootloader phone, in terms of security, is it easier to hackers to mess up my phone?
2) Is it better to lock my bootloader, if so, how can i do it, resolving my issues and not losing features?
3) If unlocked bootloader is an option, how can i have my phone back, i mean without issues? ( I read a thread about this point, but i confuse a little, because i dont have recovery or rooted)
I tried installing an ftf from flashtool, issues still there =(
Thank your for ur patience.
God bless u.

Hmm technically yes. I guess it would be detrimental if someone grabs your phone and flash's a hacked boot.img. Root on your phone is more of a risk with an internet based attack or corrupt apk.

You can lock your bootloader but it won't fix your issues as you've lost your drm keys. There is a drm fix in the cross development section I think. Google "Xperia drm fix xda". Not sure if this will fix your Facebook issue though, I've never heard of that one. To relock your bootloader google "Xperia relock bootloader xda"

Firstly, if you don't have recovery or root, why unlock your bootloader? Thats sort of the point.
Since you lost your drm keys, the best thing you can do is flash a stock ftf file, apply the drm fix and relock your bootloader. It will never be 100 percent the way it was as you can't reapply your drm keys.

Rooting advise needed......

Just received my Z5 compact on upgrade from o2, I'm distraught to find out the rooting status is bootloader unlock allowed : no
Now I'm unable to find anyway to root it without unlocking bootloader.
Someone please help or break the bad news to me if root access is impossible without an unlocked bootloader?
I upgraded to this seeing as I was so happy with my Z1 compact but I can't have a phone I can't root.
As far as I know currently there is no way to root without unlock. Probably nobody looks for a bug to allow this as TA partition backup is possible and the keys are replaced by a patch after unlock.

thank´s for this answer.
solve my question in the general threat.
Does anybody know if root is likely to be possible at some point with a locked bootloader?
As I was saying a few posts before: Probably nobody is even looking for a security hole that would allow root access with locked bootloader.
TA partition is backed up, TA keys are patched, root access achieved => 90% of the people are happy.
It's a locked device with low activity on XDA. We should be grateful for the current situation!
