[Q] Custom ROM & security - Xperia Z2 Q&A, Help & Troubleshooting

Since large part of us might get their Z2s this week (hopefully including me :silly, I'd like to know what options we have to make our Xperias secure with soon-to-arrive custom ROMs.
From what I managed to find, the most convenient option (at least theoretically) would be to:
- unlock bootloader
- flash custom recovery
- flash custom ROM
- reflash stock recovery to prevent lockscreen bypass and adb access in general
- relock bootloader to prevent flashing custom recovery and regaining adb by potential attacker.
- then if needed, reflash recovery online if rooted, reflash new/updated ROM, reflash stock recovery back
Now, I've read that Xperia Z2 (other Zs probably as well) will softbrick with locked botloader and custom ROM/kernel, rendering this method useless. Am I right?
If yes, what other options do we have?

all i know for sure is its more complicated than samsung models n im gonna wait till there a way to root it without messing with the bootloader

-Unlock bootloader
-Flash kernel of the ROM you want (DooMKernel for stock based)
-Boot into the recovery that's baked into the kernel
-Flash the ROM you want
All AOSP ROM's require fastbooting the kernel from the zip (unless stated).

I cam from Samsung also, but really not difficult to unlock Bootloader at all actually.

So there is no way to block access to recovery after flashing custom ROM?
Also sorry for probably dumb question (I'm new to Xperias): do you maybe know if current recoveries baked into CM support encryption? I know there is no CM for Z2 yet, I'm asking about current Z series phones.

Well... On newer Xperia's (2012+) you can flash a recovery to the TArecovery partition, so you could remove it I suppose... But if the kernel you are using has a custom recovery baked in (they usually do on Xperia) then you could flash back the stock kernel, if you don't want recovery on stock based ROM. but as far as CM is concerned, you cannot remove recovery.
And yes all CM has recovery baked into Xperia kernels. We'll have official CM support from FXP team as soon as they receive their device too. Good times ahead

Its not so much the unlocking of the bootloader that bothers me, i reckon i could do that. Its more the effects of it, what gets lost, stops working properly etc

Not sure, thats why i aint doing nothing to it, apparently theres a folder that contains licence keys, which you will lose when you unlock bootloader. until i know a bit more about it, i aint messing with it

You lose the DRM keys. You can't keep the DRM keys if you root as of yet, because you have to unlock bootloader to root, and you can't do TA backup without root. Vicious circle.

What would I need the keys for? Sony sends the code to unlock the bootloader.

Music info, X-Reality engine stops working and so on...

That was the one, i knew it was something important. thats why im waiting till there a root without unlocking, i could probably manage without most of it, but i want the bravia engine working and any other screen or audio stuff it affects, altho i was wondering, could you not just redownload the stuff you want and in doing so aquire new keys?? or is it not that simple?

You cannot flash kernels in locked bootloader.. And most of the mods are also there for unlocked one.. Unlocked bootloader has very few Roms.. Better unlock it and experience a whole new world for your phone
There's no different in apps or mod.
But there's rom. Most rom here are build for unlock bootloader, u can overclock and stuff.
Pretty cool but u will lose DRM keys. So no more "download music info" in walkman. All apps that need DRM keys won't work,

Yes it is, and there are guides in this forums by DoomLord.
From my own experience, the only thing I miss is walkman's "download music info" which I don't consider important. If you are one of the "flashers" I suggest unlocking it

This and other mentioned are RESULTS of difference but where is difference ITSELF ?
WHY cant I flash any kernel except stock ?
Don't tell me "because you go brick".
It is RESULT.
I can flash stock rom and it communicates with locked BL however - I think - new stock rom has it's own management of booting.
Then - base question is NOT explained and I am really curious of answer.
Locked bootloader means it can only boot sony signed kernel
NO CUSTOM KERNEL NO ALWAYS ROOT
Unlocked means it can boot any kernel made for that device
You can always have root and have custom kernels
You can also get CM and all new features
The rom for locked bootloader can work in unlocked but vice versa is dangerous

NO, bravia won't work and this is the only thing i miss from locked bootloader.
As far as i know DRM stand for Digital rights management, so you can't download music info anymore. But there are many modded walkman apps can do that.

Yes. That I did, on older stock ROM, ST26i_11.0.A.3.28_WE. Lost root after upgrade to latest.
Downgraded, prefer have root than latest ROM however speed is about 15% higher on new ROM, must be better kernel and libraries.

why would u want to downgrade? u can have root access on every ROM even if your bootloader is locked.
So for unlocked bootloader just flash a custom kernel with "autoroot" function. Once u flashed that kernel, u will have root access after reboot.
For both locked and unlocked bootloader this tool from b1nary should also work...

As the name suggests LOCKED BOOTLOADER means the bootloader is locked and cant be accessed, so you can't install custom kernels as it is locked with the kernel by Sony itself......yes you will lose your DRM keys,you cant use trackid and the download music info which are somewhat pretty useless for me........those were such small sacrifices so you can access the vast open world of modding your phone.....hppe that helps.

Hi people. This is my 3rd android device. Two samsung products, and now the Z ultra.
So I have no idea what people are talking about... I'm used to ODIN... so is flashtool a similar piece of software?
My xperia Z hasn't arrived yet, Im just trying to get my head around sony and the way their devices are run..
So.. questions...
1. Backup your TA partition (I read that this has important info that I don't want to loose... Do i do this with flashtool? Do i also reflash this partition at a later date?)
2. Unlock your bootloader (Why are some people not unlocking bootloader... Do I understand correctly that some features will stop working... like x-reality?? If so, can't they just be reactivated with a custom ROM?)
3. I see there is a recovery for locked bootloaders... (can you still flash kernel's custom ROM's zips using CWM with a locked bootloader?)
Ive spent 3 days looking on the threads here, but I think because of my previous devices I have a preconceived idea of what i should be doing.. I'm confused.

Now everyone knows you're a n00b!
First of all, the minus of unlocking bootloader is losing your DRM keys. To do this, sony has provided us an official way through their website (just google it). Or you can do this via flashtool too. After unlocking, you will lose xreality engine and won't get FW update from sony anymore through official means (pcc or ota, but you can always flash). Some says trackID will be lost, too, but hey, who use it anyway?
The plus is, you entered godmode for flashing anything into your phone.
Unlocked bootloader can be relocked through flashtool, but relocked is not the same as locked, because xreality is still lost, cmiiw. To restore to original locked state, use backupTA (search thread in xda) BEFORE unlocking bootloader. And backupTA needs root, so we need root w/o unlock bootloader first (already plenty in other threads).
And yeah, what a maze this is.

Ok thanks, that confirmed what i thought about bootloader..
Can you still flash VIA CWM with a locked bootloader?
otherwise as i understand it...
1) root device
2) backup TA parition
3) unlock bootloader
4) flash ROM/kernel/etc
5) reflash TA partition.
done... custom ROM with x-reality support?

Well it's harder to make, apparently. Currently even custom recovery for locked bootloader is not finished yet. Check the development section. And flashing things that normally isn't allowed on locked does have limitations, check in other xperia devices threads.

I am looking at getting the phone too. From what I understand is when your bootloader is locked, it will only load signed boot partitions. So any modification to the boot partition outside of the official stock kernel will not boot when locked. So installing any custom kernel (OC/UV/etc) with stock rom needs unlocked bootloader, or installing CM (which has it's own kernel anyway). So best is getting custom roms (only modified system) with stock kernel.
Also like already said, unlocked bootloader means no updates from Sony. I would backup TA at all costs anyway.
I doubt stock kernel supports kexec, but I guess you can hack the system init process to load different ramdisks. Which is why I guess they are having trouble with locked bootloaders with recovery ramdisks in the dev forum.
I am waiting for the C6806. Here are my plans:
1. Root using vroot (hope it doesn't infect TA with something ;o)
2. Backup TA Partition
3. Unlock
4. Deal with loss of DRM
5. Install whatever ROM/kernel for daily usage
6. (maybe make official TWRP)
7. Get official updates by restoring TA partition, stock kernel if necessary
or...
1. Root using vroot
2. Backup TA Paritition
3. Stick with stock kernel
4. Help with getting locked 2nd ramdisk working with stock init
5. Is the stock ROM awesome enough? (Not sure since we don't have 4.3 )
Also hoping info comes out about ATT bootloader soon on Note 3.
LTE phone is out by 9/25 I am thinking with US warranty support. (C6806)

Is it worth it to unlock your bootloader because you lose some things like apps and bravia engine....
Do you have any problems on your device with unlocked bootloader?

The only reason to unlock the bootloader is to run custom roms, we don't even need it unlocked for recovery now.
You can also restore the TA partition to regain xreality on stock roms.

I have unlocked my BL and to be honest I can't tell any difference with X-reality deactivated. But I mostly use QuickPic to view photos and MX Player for videos. I do not regret unlocking.
There is a difference but sadly is not always for the best from my previous experience.
Some things look very nice, almost HD like but very bad video quality for example just seems to look even worst lol

Bootloader unlocking

Hi guys, yesterday I just installed on my xperia z2 .726 LP stock, prerooted and with recovery. And I don't know if its good for me or no. And as the lollipop is getting updated, im thinking maybe i should go to 5.1?
The question is: Is it really worth unlocking my bootloader and going for 5.1 or I should stick with stock and with locked bootloader?
What I lose if i unlock my bootloader?
And if its worth it, can you give me the links to do it the safest way, without losing some things
Unlocking your bootloader is safe as long as your not stupid about it
You will lose your warrenty, and some xperia features spesific for the stock rom ( these are permanent because unlocking your bootloader wipes your TA partition where unique information is kept)
You can backup your TA if your device is rooted
(google will help here)
So Is it really worth unlocking my bootloader and going for 5.1 or I should stick with stock and with locked bootloader?
And maybe, if u kind, can you tell me, what rom, kernel, what do you use?

Id rather stay with stock but androPlus kernel
Stock has all the features and the look i need above any commom custom rom
And the custom kernel alows for some aditional customization as well as some patches that alow even more e.g. xposed
(easier to root, recovery is more static you could say)
If you realy dont care about X-Reality, your warrenty and a couple of xperia apps then an unlocked bootloader is for you.

Okay, if I do unlock my bootloader, i lose my warranty, xperia apps, x reality, but doesn`t restoring TA keys, gives me back all of it?
Oh and what about camera?

You lose all that but sony cant tell if you restored your TA or not when you did so yes
Camera quality on stock rom is good but on Ub its somewhat lost however the results are more honnest so to someone who is into photography UB is better
On custom roms its about that of stock, CM based usualy varies depending on the scene.

So I can unlock any time I want and I can relock any time I want. And all functions will be lost/restored if bootloader unlocked/relocked ?

So, if I unlock, does my camera becomes a lot worse? And if I relock, does my camera go back to normal?

So if I unlock, install androplus and existenz 2.0 Y , will I get much worse camera quality?

1. This only applies if you restore your TA if backed up before unlockimg
2. The camera quality doesnt even drop all too much.

So, camera goes a lot worse in CM roms?
So, I can easily go for TA backup, unlocking and installing existenz with androplus kernel, or even your kernel, if you release it ? ) (camera is important for me) (I want bigger battery life, now its 2days, with 5hrs of sot)

root 5.1.1

Hi there can anyone help Im not new to rooting and flashing stuff its just my new sony experience came from htc one m8 Im so confused with this dual recovery do I need to root first before flashing this dual recovery? because on most phone just install custom recovery then flash supersu.zip and done you are rooted, I want also some custom rom can anyone help me? im on 5.1.1 d6503
It depends if you care about your warrenty and certain Xperia Spesific features
1. Downgrade, use root tool then use prfCreator to make a pre-rooted flashable zip to upgrade back to 5.1.1
(for recovery use XZdualrecovery for sirius
2. Unlock bootloader and flash recovery and kernel or just kernel with recovery bundled with
Notes:
- Stock based roms dont need a custom kernel (custom kernels require unlocked bootloaders(
- Custom non-stock based roms need a unlocked bootloaders

It really depends on your use
Example: i benefit from a Unlocked bootloader because i can flash androplus kernel which allows me to tune my phone in such a way to where i can get an extra 2hrs of Screen time
And you lose camera post processing and those display enhancements that make pictures look nice in the album app when enabled as well as some PS3/4 related features
In my opinion the camera looks better without post processing and the X-reality isnt a permanent thing so whats the point of it really
