[Q] Upgrade to 4.4.4 z2 - Xperia Z2 Q&A, Help & Troubleshooting

i'm on EE in uk and they tend to take while with latest FW. If i root can i upgrade to a custom or overseas 4.4.4 and use remote play?
if i can't i'm going to have to suffer xfactor and downton abbey tonight so it's really urgent!

Yes, assume you are on 4.4.2. But you should know a few things first. Firstly you don't need to root to unstall a new version, just flash an ftf through flashtool. Don't Unlock your bootloader as report indicator remote play won't work without drm keys. If you do want root, follow these steps:
1. Root phone with TowelRoot or similar,
2. Install recovery for locked bootloader,
3. Install prerooted 4.4.4 zip through recovery.

Yes by all means avoid Downton Abbey. Flipping show just glorifies the aristocracy. There were flipping bas#### who treated everyone else like scum!
X factor isn't much better either. I'd avoid that too!

[Q] I need a lot of advice... thanks for looking

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.

Actually on firmware .510 with unlocked bootloader and I still have Xreality. Making your Ta backup is mainly to be able to restore your device in case of softbrick or restore your phone to stock.

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)

[Q] .257 root

I'm a total Sony noob. I ditched the galaxy note line and my beloved galaxy mega in return for my xperia ultra. Stupidly I let it update to the latest firmware (. 257) now it seems I'm stuck without a root method. I've searched around xda and it seems the only way to root my ultra is to unlock the bootloader wiping my drm keys from the ta partition. So I have the choice between having root or having x reality, Sony apps and a warrantee. Can someone please confirm if this is correct? is or will there be another way?
Android without root may as well be ios and I don't want to have to get out the mega and demote my ultra to 'work phone' status
Thanks, James
This might be correct at the present time. Previously in your situation we were doing this: http://forum.xda-developers.com/showthread.php?t=2502185. However i believe Vroot has been pulled, at least for now, due to potentially beimg malware. Haven't heard any news on that for a while now tho.

Hi James,
Let me give you the 411 on Sony devices.
Firstly Sony devices are almost impossible to brick. The only real way to brick your phone is to try and do an update when the battery is at 10% or something, and the battery goes totally flat.
(then it wont be able to hold charge, so will basically be a SD storage device that cannot retain information)
Unlocking bootloader- This is something you will probably want to do, but at a later date. The only real advantage of this is that modified kernels and ROM's can be flashed. At the moment x-reality isn't lost when you unlock your bootloader. But track ID is lost.
- You can undo this
Root - It's highly unlikely that IMEI numbers were harvested. They were ready, but we don't know anything else.
- You can undo root
Backing up your TA partition - (done after Rooting) This is done so if something goes wrong, then you are able to re-flash your TA partition, and restore your device back to stock, and still be covered under your warranty. Inside this partition, is a store of device information. DRM keys, IMEI, MAC address... etc.
- You can undo this
Recovery - Im sure you know this...
Essentially what every you do you can undo. Sony are really dev friendly. Kind of what Samsung used to be like.

Link doesn't work. Yes, you can get root, back up your TA, get recovery aaand I don't know what that link does, so I don't know. But you can install SuperSU and remove the root app from vRoot. Keep in mind that it's not the vRoot root app that's suspicious but the desktop app.
Still, we have no idea at this point so you can either root and live with it or you can wait it out and see what the investigation brings up.

I used the vroot method. Nothing is confirmed and for me I felt it was worth the risk
Does anyone have a TWRP or CWM recovery image that can be flashed and booted on. 257? Or do you have to flash the CWM kernel, flash any zips you want, then reflash the .257 kernel in order to boot up and run? Is the recovery always tied to the kernel on this device? A lotta questions, i know

2. when i root my device, is there a posibility that the X-reality engine will not work properly?
3. ive read that the device can be rooted even if the bootloader is locked. If i decided to unroot it again, can we do that?
4. is there a flash counter in xperia devices just like in samsung where in you can see if the waranty has been breached already or not?
5. can we turn the device to its original state again after rooting, unlocking and flashing custom roms?
6. if device is rooted, can we still install new updates from Sony thru OTA?
thanks,
Have a great day!

Yes you can unroot just by flashing a Stock Sony ftf over the current one via flashtool. Preferably the same firmware( without wiping)
Also, there is no flash counter in Xperia. If you have a locked bootloader and it is unrooted, there is no way to tell if you have unlocked or rooted

No problems with NFC here.
There are different ftfs for different regions. But that's not a problem. You can flash any region's ftf for your specific model number. If your model is 6833, then download any .757 c6833 ftf and flash it. Have a nice day

A couple of rooting questions

I have a couple questions to ask about rooting this device.
I have a UK model with unlockable boot loader. Everything stock on the device.
1. Is there a root out yet that doesn't require unlocking the boot loader?
2. Can I root without voiding my warranty?
3. Can I easily unroot and leave no indication of it being rooted, to make a warranty claim if ever needed?
4. Do mobile banking apps still not work on rooted devices?
5. Does rooting slow down your device?
Thanks in advance
Sent from my D6503 using Tapatalk
1. Yes there is a full root thread on the Original Development forums for the Z2
2. No, your warrenty will void with root however removing and flashing a stock FTF it will restore your warrenty as your Z2 no longer contains modified content
3. You can unroot via the app and there will be noticable changes unless you used root to modify but then you can flash a stock firmware
4. They should. Very few apps actualy check for root
5. Rooting does not slow your device

Almost all Xperia 4.4 xposed/modkits/etc work for any Xperia with 4.4 KK aka Z2 with 4.4

So I can root without unlocking boot loader, and then just unroot to restore warrenty if/when needed?
I have looked through some threads and a little confused about if the phone has to be downgraded to root? The build number ends in .402, so can I root easily?
Thanks again, I do appreciate you taking the time to help me

Yes you can root without unlocked boooader as of posting this
You can restore warrenty by removing root
I think you can stay on 402 to root, not sure, look at doomlords thread in original development

I never ended up rooting my device, but decided now is the time.
I am on 17.1.1.A.0.402
Bootloader is unlockable, but currently locked (and will be staying that way.).
Does anyone know if there is a way I can root it without unlocking bootloader and without downgrading firmware?
Thanks in advance

yes you can root easily now with locked bl (thanks to all the devs that contributed btw), you can upgrade to .314 and root that easily too, you can then restore ftf to stock and keep warranty. or you can also root, then backup TA, then unlock BL and do whatever you like. you can restore that TA backup later to get locked bl again and restore ftf to stock and keep warranty.
Thanks guys.
Is there any super simple step by step guides for doing this?

Before you root, you should read the threads in the dev section as potentially you are unleashing a beast which can brick your device.

HELP - First time to root my Z2

Hey Guys,
So I just bought a Z2 with Android 4.4.4, and after a lot of reading I understood that there is no "one click" rooting option for it and that I have to downgrade first and then flash a rooted ROM.
The thing is I checked all the the current threads and they are somewhat very hard to follow through and a little bit made to advanced users
Topics like: http://forum.xda-developers.com/xperia-z2/general/4-4-4-creating-rooted-update-package-t2933155
So sometimes midway they skip a step or dont explain how did they reach there (specially after step 9 in the above tutorial)
I know I am asking too much, but will someone walk me through how to root my locked boot loader phone ?
FW: 23.0.1.a0.167
Thank you very much
There are 2 ways to root
Safe way which is this way which includes downgrading and having to reset your device twice
Or the easy way which is unlocking your bootloader (losing your TA and DRM Dependant features) flashing a custom kernel + recovery
You cant root at all without losing data
Hi mate
I suggest you to try this method first
http://forum.xda-developers.com/crossdevice-dev/sony/giefroot-rooting-tool-cve-2014-4322-t3011598
It doesn't work for me and if it doesn't work for you too we can talk to the author to support our devices
with my best regards

Hey Mate , Thank you for your reply
I have tried it but it didnt work, it says my "phone isnt vunerable", I have sent to author waiting his reply.
If you have any other pointers for me that would be great !

I have also the same error now we are sure that our devices are not supported yet I think he needs some informations about the kernel.
I sent him message and I got a reply but he thought that I have 4.4.2.
He told me that he is busy.
I sent another message and I'm waiting his reply.

Then How to do it even with losing data, but not losing the original FTF ?

Its not too complicated, but im sure its 100% safe. The step only required downgrade and then install the pre-rooted rom. If you know how to flash with flashtool, then this is not a big problem. Before you begin, please make sure you understand each step that you gonna do. This is how actually i do.
1. Download all files required(ftf, rooting tools, prf creator, recovery, etc)
2. Make the pre-rooted rom first.(i just skip that step 11)
3. Flash the stock .314
4. Root & recovery it.
5. Insert that pre-rooted ftf that i made early, in my case i also use a stock rom .167
6. Reboot and finish.
I've rooted Xperia Z before and I'm sure it was much easier. I'd like to root my Z2 but it's much more complicated. I mean I know how to use flash tools, but I'm a bit lost when it comes to drm keys. Is it possible to root and unroot if needed so Sony won't know if anything goes wrong ? Does your method involve drm backup?

This method doesnt require to unlock bootloader, its safe. Backup drm key can only be done after u root your device.

Yes root doesn't harm your DRM keys only unlocking the bootloader will do that and here are so manybthreads howto get root on locked bootloader, just search before posting and read the rules !!

Yes rooting doesn't Unlock your bootloader so no loss of DRM keys. Its theoretically impossible to hard brick a locked boot loader Z2.
