[Q] Flashing questions

Hi, i got my Sony Xperia Z1 today and I want to do all the tweaking and flashing things. So, according to what i read i should do the following:
1- Root phone with some root program
2- Backup TA and DRM keys: don't know what drm keys are, neither how to backup them...
3- Update to ftf .290 (4.3)
4- Unlock Boot loader: Will this void warranty? Saw people saying that with TA backed up I can restore warranty as well, but at sony website it says it will void. Can someone clarify this to me?
5- Root again: Why should i root again? In which previous step I lose root?
6- Flash kernel with flashtool (or adb): Which are the best kernels? I will flash doomlord kernel for now
7- Flash custom rom: This is my main question. Which are the best 4.3 roms? I'm taking a look at iHacker, Monx, and PAC. Looks like PAC doesn't have camera working, can someone confirm that? About iHacker and Monx, there isn't a bug list, so i wonder if they are perfectly working, including camera..
Thanks

1 yea root phone
2 yea backup your TA and DRM there is a tut on the forum just search
3 yea update to 4.3 so u can unlock your bl without losing camera function
4 yea it will void your warranty and ya you can relock your bl with your keys there is a tut for that too
5 u have too because u loose root when u update but it is still a work in progress so read around and see what method works
6 doom I think is the way to go
7 try then out and see which one is better for you...I haven't used any of them so I don't know what bugs they have

4- But if i relock will i get my warranty back? I mean, they will be capable of knowing that I unlockd in the first place?
7- So you are using stock? I'll ask in the roms thread for what works. Just thought that asking once here would be better =)
Thanks for the answers!

Rooting is it really worth it?

Hi I am new to super smart phones like the z1, I'm the type of person to want to hack things and make them beret but I'm also the type of person everything goes wrong for. I want to know if it really worth rooting my phone what I would gane and if it worth the risk,? Thanks

Some of the Benefits of Rooting:
1. Easily backup your apps + data to your Ext sd card (no PC required)
2. Remove bloatware (pre-installed carrier apps that you cant remove without root)
3. Full customization of your xperia z1. Examples: change your navigation bar layout, add 3 dot menu bar, customize your status bar, assign different actions to your hardware buttons, increase/decrease height of your navigation bar etc
4.Flash custom ROMs and kernels (if your bootloader unlocked)

5.Overclokking.
6.Improve Battery life with Frequencies and Governors.
7.Full access to your System phone.
8.Modified build.prop to make uncompatible, compatible apps.
9...and more...

anyone who is asking this question shouldn't mind if he needs root - you need root ^^
there should be no problems if you read the instructions and immediatly ask questions when there are problems

So if I root my phone will all the stuff I have on there already stays there or does it wipe it. What happens when new updates come out? My warrenty stops to doesn't it? I would have to flash a stock rom if i have any problems? so the phones functions all work the same Ie connecting a ps3 controler? Just worry I'm going to screw it up or loose things to gain things

Unlocking bootloader might do that, but not root.

So rooting my phone will give me more control and customisation. Still keeping installed apps and game progress? Un locking bootloader will change everything and loose everything?

You don't loose anything when you root the phone.
When you unlock the bootloader than yes you will loose a few features such as Bionz and also the Xperia Throw.
Here is a video that should clarify a few things for you:

First question is what version of firmware you are on. To get a fully functional root on 4.3 firmware (with write to system ability) you need to unlock the bootloader first.
You can have a partial root on 4.3 that will still allow use of Titanium Backup or Xposed Framework. To get root you need to use Flashtool to downgrade to old 534 firmware. Than root with vroot (check out my channel for video). Than install dual recovery. Once you have root and recovery flash a prerooted rom. I would highly advise using monxdified rom.

When you go to Settings>About Phone under Build Number you will get the firmware that you are on. To root the phone you need to downgrade to .534 firmware. This place is to ask questions, but there is a search function for a reason. When you ask the same question for 100th time you just flood the forum. Your question on why you should root has been answered. If you want to find out how to do it read on the respective threads.

I did a backup of TA partition, then I updated to 4.3 (290) and unlocked bootloader in order to flash TWRP and flash SuperSu. All was nice, except for x-reality didn`t work (which i dont care so much) but I didn't know if BIONZ camera image processor stop working too.
This is my only concern. I want to know if its possible to have unlocked bootloader and root without loosing BIONZ processor. I tried restoring TA partition while unlocked/rooted, but it became in a soft-brick which I only could solve flashing a ftf.
Thank you very much!

When you unlock the bootloader you loose the DRM keys.Technologies such as X-reality Engine or Bionz will not work with bootloader unlocked.
When you restore your TA do it on the same firmware that you did the backup on. There have been issues reported when trying to restore backup from 4.2.2. on 4.3

But it's possible to have a working camera without bionz working? (such it happens in 4.3 after unlocking bootloader).
I can only do TA backup in 4.2.2 (534 or 257) because are the only rooteable versions. And I only can unlock bootloader in 4.3 because it's the only version which doesn't lose camera functionality. How it's supposed to be root and restore TA in 4.3?
Thank you.

The camera works on 4.3 when bootloader is unlocked. You are going to loose bionz and x-reality. You cannot relock the bootloader on 4.3 if you want to have a functioning root. It's either one or the other. When you restore TA you will relock the bootloader.

Unlocking bootloader allowed, why not root?

If sony is completely fine with us unlocking hte bootloader, as shown here: http://unlockbootloader.sonymobile.com/unlocking-boot-loader
Why did they make it so difficult to root the device?

If you can unlock the bootloader it is a very easy 2 second job to root.

But id have to downgrade my firmware. And my data would be erased. Seems so needless

That's only to back up TA upgrading with root from 4.2.2 is to 4.3 or 4.4 is not supported.
Upgrade to stock then unlock
Also I think losing all data is a sacrifice worth it besidesvyou can back up data Sony provides you with the tools or just copy SD card to desktop and restore when done.
OOORRRRRRRR.....
You can get pre-rooted firmware here http://forum.xda-developers.com/showthread.php?t=2711982
Backup TA and unlock(if you want but I'm getting the sense that you just want root)
The last option is the preferred one no downgrade pain nonsense.
And finally to answer your Question: Sony is gonna Sony they say they don't mind you unlocking boot loader but the remove the good stuff like BIONZ. Now just imagine with root in which they never claimed to not mind about.
yup owns Z1 and stuff.

As for unlocking bootloader there's no hope. But you can still get root by flashing pre-rooted firmware in the link I provided in previous post. Just follow the locked bootloader instructions.

what does sir?
"Rooting Status:
Bootloader unlock allowed: Yes"

Why dont you search before asking? I wanna tell you some problem after unlock bootloader:
4.2: Camera doesnot work (BIONZ is disabled)
4.3: X-Reality doesnot work, camera still work
4.4: X-Reality + Camera still work
BUT DRM KEYS ON TA PARTITION WILL LOSS FOREVER IF YOU DO NOT BACKUP BEFORE UNLOCK BOOTLOADER, AND ALSO YOUR WARRANTY.

i dont have the warranty anymore so 4.4.4 is the best to unlock cause x-reality and camera still works?
can you help me unlocking sir?

The help had already been given. Follow the link I posted above and read it and do what it says

It is recommended not to do that first, but to root first
That way you can backup the TA partition to relock your bootloader and restore your DRM keys if you want to. If you unlock first then you lose the DRM keys forever.

Where can I find the specific TWRP thread? (and no it is not in your signature) I know that downgrading is not necessary for unlocking the bootloader but I will loose the camera if I do it on the latest firmware right?

It is, just click on "XZ2 Development"
It is the camera preview and no, if you use the newest firmware, you won't loose it.
But it will fullwipe your phone.
Sony Backup & Restore won't work after unlocking.

1. Yes, the camera will still show the preview and shoot pictures.
2. No, Sony Backup & Restore needs a working DRM.
You could use Google Backup or maybe there is some hack to root a locked xperia xz2 to use another backup solution.
Maybe a compiled stock kernel with this commit
https://github.com/j4nn/sonyxperiad...mmit/549389a03bfca69c8d2a8237b7d41c36105619df
will let sony backup & restore work on an unlocked phone, but I sadly have no time to compile it at the moment.
