Hi All.
I am new to Sony after having a samsung GS2 for many years.
While I am familiar with the rooting and flashing process for the GS2, I am still getting my head around the Xperia Z1.
From what I can see I need to do the following,.
Root Version.
Backup TA
Unlock Bootloader
Flash CMW Etc
Flash Roms.
I am a little stuck around the Spony version numbers though.
My Z1 is on 4.2.2 and Build no 14.1.g.2.259
Is there a root method for this version, or how can I change to a rootable version?
Thanks in advance.
Cheers
Hey I followed this guide:

It was the same as on my xz, you first have to downgrade your phone, then you can root it. This guide also upgrades your phone to the latest official 4.3 and installs CWM and TWRP. If you want to install a custom rom, you also have to unlock the bootloader. Before you do that, back up the TA partition. There are plenty of tutorials about unlocking the bootloader on the internet, I suggest you use flashtool because I've unlocked a lot of bootloaders with that and never had any problem.
Another way is to first unlock the bootloader, then install a custom kernel. This also should root the phone.
Good luck!

Thanks for response
With the second suggestion would I be able to backup the TA partition prior to doing this as we need root to do that first don't we?

290 and 136 have chance to be rooted if your bootloader has been unlocked.

Yeah you can't backup the TA first, that's a risk you have to take than

Hi Again,
When downgrading to a lower version as shown in the video, does this have any impact on the drm keys stored in the phone, as they wouldnt have been backed up.
Thanks.

Hi,
I have the latest stable CM installed on my XZ, but I miss the Sony ROM, so I thought I'd revert back, though I'm a little unsure about how to so it. Before unlocking the boot loader and installing CM, I rooted the phone and made a backup. My question is;
Can I revert back by doing this:
1. Booting into flashmode, wiping the cache
2. Choose to reinstall my back-up file
3. Relock boot loader in flashtool (if necessary, it was locked when I backed up)
4. "Repair phone" in Sony update service
And then be back to how it was before?
Seek and you shall find. Or look at the stickies!

Thank you!
But that doesn't really answer my question(s), and as they were very specific in nature, a simple "yes" would be sufficient, or a "no"m, accompanied by the aforementioned links. ^^
I'm new at this, so that post has a lot of information... That's why I asked in a separate post.
You can just flash stock rom with flashtool. You don't need to relock unless u backed up your ta partition and you want to have bravia engine and updates.

I was wondering if it was possible somehow. I backed up the TA-Partition and I defenitly want Bravia Engine back. How should i do this?

Since it's so hard to get a reply regarding my original post, I'll ask it like this;
Can I flash an official sony rom (.ftf) over my CM10.2? If so, can I just relock the bootloader through flashtool as well to get back BE2?
The key to get BE 2 working again and have fully restored DRM keys is to restore the backup of the TA partition that you should have taken before unlocking the bootloader. Flashing stock FTF and just relocking bootloader won't do the job
Neither will a CWM restore.

I made the backup in cwm before I unlocked the bootloader, is that not usable to get it back? Is there any other way?
Unfortunately, CWM doesn't backup Trim Area (TA).In your case it seems Sony DRM keys are lost forever :thumbdown:

I see. Oh well. BTW, I unlocked the boot loader once before, but then I relocked it without making any changes. Did I lose BE then, or not before I installed CM? And what other than BE will I have lost? :/

Yes you loosed it. If you unlock you booloader you loose the keys. That is the reason why you have to make a TA backup before unlocking.
Your warranty you loose also but I think you should know that
Heyy guys I have a XperiaSP which have unlocked bootloader and unrooted phone (just unrooted it a while ago). I would REALLY like to update my phone because there's too many bug here on Xperia SP. However, when the phone was still rooted I tried to update and it failed. Now after unroot I was going to update but then the fact that I unlocked the bootloader I am really worried about wiping/bricking the phone through OTA update. Any help pls?
P.S - My phone is barely Unlocked. It is nearly as stock and no custom recovery nor root is installed.:laugh:
Edit : By the way, is the Xperia SP really got Wi-Fi issues? My iPod got full signal on home's wifi and my SP got barely 1-2..
hmmm

Or else I think you know that Sony's 4.3 update is on the corner. that may will solve your issue

Ahh yeah gonna try that ASAP. but I just forgot to mention that my primary laptop is now on service center (Got a bit problem there) so I can't really update my SP through that.
I tried updating just now through OTA. After the reboot a popup message appeared :
"Could not install new software version. Try again."
Is that because of my unlocked bootloader? Cos I unrooted my phone completely through SuperSU.
If so how to relock the bootloader??
If you want to relock the bootloader just use FlashTool. In your case because you don't have any custom Firmware on your phone this should be quite easy.
But I always thought when updating with having root access you can update but lose root. Maybe it didn't work (the update) because of a complete diffenent reason. Did you try it a second time?

When I got my laptop back, I'm definitely going to relock the bootloader. But if I do something wrong, will it hard brick or something? (sorry for my parranoidness) and relocking is not much difference from unlocking right?
I tried installing the software update the second time. Unlocked BL, fully unrooted (No Super SU). Still fails gonna try at PCCompanion

I'm on my stock ROM now (Default Sony ROM right? But I've updated it before, does it count as stock?)
What's TA partition?
Sorry for noob Qs
I never do this before.So can I update my phone via pc companion via unlocked bootloader?On stock rom without root and recovery?

If you didn't flash anything on your device you can relock your bootloader without any problems. If you had a custom recovery, kernel or ROM and you relock your bootloader while having this custom recovery, kernel or ROM this should brick your phone (I think this could even be a hard brick) but if everything is stock (like I already said) there shouldn't be any problems with relocking
TA partition contains the working bravia engine (2) which gets lost if you unlock bootloader. If you had made a backup of the TA partition you could restore this and get the bravia engine back

if i didnt make backup (because no one told me to ) i cant install 4.3 update from Sony if comes out ?
Yes, you'll be able to get the 4.3 update without the TA partition. But, as everyone else here said, make sure you're on a stock ROM, with a locked bootloader.
Locked bootloader ----> You can use PC Companion or Flashtool to update your phone
Unlocked bootloader ------> Flashtool only
Also, don't try to update your phone via OTA while having your bootlader unlocked, because it will brick your device.

My original Stock Rom had been flashed to CM 10, but now I have flashed it back to stock rom that I tried to search online from this site. Is it counted as original stock rom or not? My phone is unlocked bootloader, and I got ota update but cannot install, I don't know why; maybe it has been changed or maybe of unlock bootloader?
Hey guys is it safe to unlock the bootloader running 4.3 build #290
I dont quite understand the TA backup
Its my first time to own a non nexus device so im a little scared to unlock my bootloader with other things to do
Anyhelp will be much appreciated! Thank you!

You need to backup your ta partition for warranty reason and some xperia features to work.
First root your device then backup your ta-partition and then you can safely unlock your bootloader.
To root your device Out most likely have to downgrade your firmware, then root, then backup and then you can go ahead and unlock your bootloader with the latest version of flashtool

If you don't backup TA and DRM keys and you Unlock Bootlader you will never Relock your bootlader again, you will lost warranty forever and features like X-Reality, Bionz Processing and Bravia Engine.

Don't be, I remind you that Unlock Bootlader is necessary if you want to flash Custom Roms with Custom Kernels Only, if you will not do that, you easily can Root, Install Recovery and Custom Roms on Locked Bootlader.
Hi guys thanks for the quick response imma try the thing without unlocking thw bootloader and installing dual recovery

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.

I did not thought that the first question of the OP was to root the phone ....
Hi guys. I have recently signed up here and am currently a XDA and Android noob. But i do have some experience of rooting. (I often watch one of my relative root and do stuff with odin but only for Samsung). I currently own a SONY Xperia ZR C5502. It has android 4.4.4 KitKat.
And i have no idea how to root it or load it's boot screen. I'm trying to install CyanogenMod or an android lollipop ROM to it.
If anyone is kind enough to give me some advice or help I'd really appreciate it.
Thanks
Ahmed
Hi Hardwelling, Welcome to ZR Forums
i was a samsung user one day so i know what you feel now
For Sony Devices, to flash ".ftf" ROMs, flash kernels..etc , you should use Flashtool
It's the same as ODIN.
First
For Rooting your device you've several ways :
1. Root the device without unlocking bootloader (you'll not be able to flash any other ROM not based on Sony Stock one)
2. Root the device with unlocking the bootlader. (you'll lose your DRM Keys , however there are ways to Back them up, search xda for further information about DRM keys)
for both of them, you may search in the forums and you'll get a lot of methods (towelroot, Pre-rooted ROMS..etc)
Second
Installing Custom Recovery.. you may find plenty of them here, but i suggest the best one NUT's Dual Recovery,it works for both Locked Bootloaders and Unlocked Bootloaders.. Here you'll find all recoveries for Xperia Devices, make sure to choose the one beginning with "ZR", and go the "Installer" way, much faster
Third
Flashing custom ROM, it depends on what you have [LB] or [UB]..
Locked Bootloader Devices can't run CyanogenMod or AOSP ROMs..etc, as it only allow Sony signed kernels.
Unlocked Bootloader Devices allow you to run any kind of ROMS even Stock ones, but you'll lose some features of the Stock one as you lose your DRM keys
For myself.. i'm running Rooted LB Stock 4.4.4, and previously i was using this ROM
Use Flashtool to unlock the bootloader using SONY's official way..go to sony website and follow the steps there
Install the NUT's dual recovery using the installer..
Flash the pre rooted AOSP build :thumbup:

I would not recommend this approach as you will lose your drm keys.
Just follow one off many rooting guides wich you find on this forum.
After that take a backup of your TA partition with TA-Backup tool wich also can be found in this forum.
After this you can safely unlock the bootloader.
