Hey guys, I've rooted, installed CWM Recovery, Unlocked Bootloader, and installed CyanogenMod on another phone before.
The thing is, I've had this phone for about 6 months and wanted to do the same. However, after browsing through the forums, man are there a lot of scary sh*t going down. I would like the request the procedure to install CyanogenMod safely, without losing any Keys/IMEI/XReality/DRMkeys/Etcetera.
I dont know if the method given by FXP is supposed to be this straight forward, but I too like others, do not want to risk losing important stuff if it can be avoided (Keys/IMEI/XReality/DRMkeys/Etcetera).
HOWTO
Install instructions:
first time
- power off the phone:
- hold vol+ and plug usb to boot into fastboot (blu led)
- fastboot flash boot boot.img (from cm10 zip)
- fastboot reboot
- enter recovery, on boot led will be violet for 3'', during this period press vol+
- flash rom zip
- flash gapps zip
- wipe
- reboot
for update just flash rom zip from recovery
Google Apps are not included in this ROM. You'll need to find those yourself if you want them.

Frankly speaking, the forums is pretty much jumbled up, and the existing [Guide] Threads are either incomplete (Lacking important steps), or Unclear (Non-Specific steps).
Perhaps someone could do me a favour by using the template that I have below to help me, and possibly others, to install CM 10.2 on our beast of a phone.
Template:
1. Backup TA and DRMkeys and stuff: http://forum-xda-developers-com/backup
2. Root: http://forum-xda-developers-com/root
3. Recovery : http://forum-xda-developers-com/recovery
4: Unlock Bootloader: http://forum-xda-developers-com/ulbl
5: Install FXP's CM 10.2 :http://forum.xda-developers.com/showthread.php?t=2461286
Something like that would suffice I think, as long as no important steps are missing that would cause me to lose stuff unique to my phone, that cannot be recovered if I didn't back it up.
P.S. My version is 14.1.B.2.257
P.P.S. Thank you in advance.
1. Root
2. Backup TA (VERY IMPORTANT)
3. Install Recovery and unlock the bootloader, or the other way around. Both ways work.
4. Install ROM by following the "guide" that you quoted above.

I'm on 14.1.B.2.257, I believe reverting to the previous version causes data to be lost unless you back it up right. *Sighs* How troublesome.

you will have to back up the data anyways. I think unlocking the bootloader does a factory reset, as well one is needed going from stock to CM if i unforget correctly
I am also wondering about this. I'm currently running firmware .257.
I understand that I need to back up the TA partition first (though I'm not exactly sure on what I will loose if I don't). I also understand that to do this I need to root the stock rom. I understand that in order to root, I'll need to first downgrade to an earlier firmware using flashtool. However, after that I'm not so sure what I need to do. As far as I can see, the only method of gaining root currently is to use vRoot, which is currently under investigation for IMEI mining.
How else can I root the device? I was thinking of maybe using the recovery for locked bootloaders here: http://forum.xda-developers.com/showthread.php?t=2426739
Following by flashing SuperSU from recovery as per usual.
Will this work, keeping the TA partition intact so that I can back it up before flashing CM? Assuming so, would I even need to downgrade from the .257 firmware at all?
Thanks,
i have CWM now so can flash custom roms like i did on other phones right?
what does unlocking the bootloader give me? unless i'm wrong and i have to unlock to flash?
all i've done so far is do a backup is all. (did a TA backup a while back though)

OK, so looking into this further, you already need to have root to be able to flash the "CWM for locked bootloader" rocovery. So as far as I can see, the only way to get root in order to back up the TA partition is to give your IMEI to the Chinese via vRoot?
Thank god the stock rom is so good.

You have to unlock the bootloader to flash custom ROMs. You can flash stock ROMs without unlocking it, but you have to unlock it if you want CM, PAC, PA etc.

really, so what would happen if i tried to flash an aosp rom now? would the system partition essentially be read only?
sorry for the Qs but haven't had a locked bootloader since the htc desire (although the s-off for that one was to remap the partitions to allow more room for data) and the reasons for unlocking don't seem to be the same.

Nothing will happen if you try it now. You can easily unlock the bootloader by going to Sony's Dev site, request your key and use Flashtool to unlock it. It takes a couple of minutes once you have Flashtool and the drivers installed. It's also perfectly safe to unlock it and you will lose your warranty. BUT you can easily relock it again if something happens to your ZU and the warrenty will be back.
Remember to backup your TA before you unlock your bootloader. It contains a lot if device info and your unique DRM keys. Unlocking the bootloader will wipe the system partition, but you will still have root, photos, music etc. (But do a backup of those just in case).

i think that's where i got confused with drivers - unlocking.
i have already done a backup of my TA part so that side of it is ok. i'll leave unlocking until there's a rom i want to try. possibly a complete 4.4 or something.
cheers LM

If you've already backed up your TA, it means that you have the drivers installed, so job done All you have to do is to install Flashtool and get your key from Sony (which you will get on your email straight away). Either way, just ask here if/when you want to unlock it so we can guide you through it (it's very easy though).
ran flashtool but gave me driver errors - missing. unable to install the drivers included (i guess due to windows 8 driver signing)
GETTING YOUR ULTRA ROOTED AND
READY FOR FLASHING
This guide should in theory make your Ultra ready for flashing custom ROMs, and with that said...
...here comes the warning: Your warranty is now voided. I am not responsible for bricked
devices, or whatever you might end up with.

BACKUP YOUR TA PARTITION BEFORE YOU UNLOCK THE BOOTLOADER
IF YOU'RE NEW AROUND HERE AND YOU WANT TO ROOT .757, DOWNGRADE TO .532 AND ROOT, AND THEN BACKUP YOUR TA PARTITION. PROCEED TO UNLOCK YOUR BOOTLOADER, UPGRADE TO .757 AGAIN AND ROOT BY FOLLOWING THE SHORT GUIDE HERE.
ROOT ALL THE THINGS:
Thanks to @geohot, we're now able to root (almost) all the things, meaning there is now one tool for rooting. This tool doesn't touch the bootloader, so it also works on locked bootloaders. Be sure to backup your TA partition after you've rooted (in case you want to unlock the bootloader). You can find the tool here.
Note: This tool will not work on the GPe model.
ROOTING .108:
Go to this thread and follow the steps.
ROOTING .757:
Same procedure as with .681, so just go to this thread and follow the steps. Requires an unlocked bootloader.
ROOTING .681:
Rooting .681 (first KitKat build) is pretty straight forward and requires an unlocked bootloader.
After that, just flash the kernel and then SuperSU. You can download and follow the short guide here. The kernel includes Recovery.
ROOTING .290/.136:
.290
• Unlocked bootloader: Follow this thread.
• Locked bootloader: Follow this thread.
.136
• Unlocked bootloader: Follow this thread.
ROOTING .532:
• Use this tool to root
ROOTING GPe:
GPe OWNERS: DO NOT TRY TO FLASH FTFs OR OTHER "XPERIA" ROMs AND KERNELS.
YOU WILL BRICK YOUR DEVICE.
Go to this thread and follow the steps. Thanks to @blueether.
DOWNGRADING:
• Download and install Flashtool (if you're running Windows 8, follow this installation guide) (Jump down to "Part 2" of the guide)
• If you're having issues with driver installation, install this one.
If you have issues, or simply have no clue how to install ADB and Fastboot, install and run this.
• Download NUT's 532 firmware from here
• Flash it by following this short guide
BACKUP TA PARTITION:
The TA partition holds all your unique DRM keys, and X-Reality won't work without it (except if you're on .681 or later).
Once you lose it, you can't get it back, so back it up and upload it to your Dropbox or something. So how do you backup your TA partition?
• Download this tiny tool on your computer and run it.
Here's a video tutorial by @hamdogg
CHANGE CDA (OLD):
This step is no longer necessary.
• Install a file explorer from the Play Store. I recommend Solid Explorer or ES File Explorer.
• Navigate to /system and open build.prop
• Change your CDA to: C6833_1275-8026 (there are three different places this has to be changed.
Just take your time and try to find something that resembles the CDA code above.
• Next you'll want to find "ro.somc.customerid" and change it to 436
• Next you'll want to find "ro.semc.version.cust_revision" and change it to R11A
• Now reboot your device
• The OTA update should arrive now. If it doesn't, go to "Update Center" (app) and manually refresh.
• Update to 257
• The root app (i'm not sure what app it installs) might be gone, so just install
SuperSU from the Play Store if it's not in your app drawer anymore. Update binaries and choose "Normal".
UNLOCKING THE BOOTLOADER:
This may wipe your phone, so backup your stuff
• Go to Sony's dev site
• Request the unlock key and check your mail straight away. Email is quick these days.
• Open Flashtool on your computer (yes, the one you installed earlier)
• Click the "BLU" icon
• Follow the steps and enter your unlock key
INSTALLING RECOVERY AND TWRP:
• Just run this tool on your computer.
• Boot into Recovery (POWER + VOL UP)and take a NAND backup ASAP.
It'll "save your life" (or time) when you're soft bricking your Ultra.
FLASHING A CUSTOM ROM:
• Find a ROM
• Move the ROM (and gapps if it is required) to a folder on your Ultra and remember where you put them
• You'll see that you'll need to flash a "boot.img" before you flash anything, so download this
• Now go to this thread and download QuickIMG and follow the short guide
• Flash the boot.img
• Now unplug from the computer and enter Recovery by pressing the Power button.
Once you see the green LED, push and hold VOL UP. If you fail, just press and hold POWER + VOL UP until you
notice some rapid vibrations. Now try again.
• Once you're in Recovery it's the usual stuff. Flash the ROM and gapps and wipe data/cache/dalvik etc.
• Reboot
BACK TO STOCK:
So you have to send your Ultra to a service center and you want to get it back to 100% stock.
Be sure to be on a STOCK kernel before restoring the TA partition or re-locking the bootloader.
• Restore your TA partition using the tool from the "Backup TA Partition" part of this guide.
• If your bootloader hasn't been locked by the TA tool, use Flashtool and press the BLU button and choose "Relock".
• You may not be able to boot now if you're on a custom ROM, so fire up Flashtool again and flash a stock ROM.
BLINKING RED LED:
So, you locked it while on a custom kernel, and all you get now is a blinking red LED above your screen.
Simply unlock the bootloader in Flashtool again, and it'll work again.
You should now be back on stock, un-rooted and with TA and bootloader in place. If you're back on stock,
but the bootloader is still unlocked, get back to 532, root, lock the bootloader, and then flash a FTF in Flashtool again.
BOOTLOOP:
You've ended in a bootloop and you have no idea what to do. A bootloop is when the boot animation is looping, and you're stuck.
We'll start out easy and go harder as we go down the list.
• [SAFE] Boot into Recovery and wipe cache and go to "Advanced" and wipe Dalvik. Reboot and see if it boots now.
• [SAFE] Boot into Recovery and re-flash the ROM and see if that does the job
• [WIPE] Boot into Recovery and wipe data (this will wipe everything) and reboot
• [WIPE] Boot into Recovery and flash a different ROM (wipe data after flash) and reboot
• [LAST RESORT] Fire up Flashtool and flash a stock FTF and get a new hobby
MISSING IMEI:
You downgraded from 290 or later, didn't you? Well, you'll have to update again or flash [NUT]'s .532 build.

Yes it strange as it only happen with my latest back-to-stock. my stock backup is with rooted .257 where as far as I know still don't have proper kernel+recovery like .526 or .532 has.
Bread guide will help me when I want to get gpe rom on my ultra.
Nice guide, where was it last week?
Would it be possible for you to add a "So you need so send your ZU back to Sony" section covering restoring the TA partition and relocking the bootloader?

here is a video I made on how to backup TA partition. also discusses what to do to restore your TA partition..
youtube ID : 8TowVR7CNQQ
I'll do a more comprehensive video in 3 days I hope... but for the moment this should be fine.
feel free to shove that in the OP
PS... can't believe that I'm the only one thats said thanks so far... tick... tick... BOOM!
Alright, i can add the "going back to stock" part, but i have never relocked the bootloader and restored the TA, so i'm not sure in what order we should do it. Relocking the bootloader is easy. Just use the TA backup tool and restore your backup, and it will lock the bootloader again. But, here's my question. This requires root, so we can't do it when we've flashed the stock firmware using Flashtool since we'll lose root. So i guess if a person is running CM, he'll have to restore TA and also lock the bootloader while on CM, but this will cause a soft brick, but then he can just flash the stock TFT in Flashtool?
Any ideas? I'm asking because i don't want to write something that's not 100% right.

I ever restored TA backup once but that was before I flash Cm at the first time.
When I back-to-stock by restoring nand, bootloader still unlocked.
I wondered if we have nandroid stock (with locked bootloader) , then we unlock, then we flash CM or other custom roms,
can we then just restore the nandroid stok (with locked boot loader) without any problem and we will have our TA partition back and relocked without restore the TA first?

When I sent mine in for repair I had to reroot first... But most people will be rooted.. so:
1)restored the TA partition,
2)locked the bootloader (checked after restoring the TA partition and it was still unlocked)
3)flashed a stock FTF.
Then it was completely stock.
Post this in the OP for locking bootloader
____________________________________________________________________________________________
Download the latest flashtool from:
http://ul.to/3kjpyj70 [v0.9.13.0]
Before you relock the bootloader you have to be on a stock kernel or else the device WILL NOT BOOT.
-We recommend that you will need to return to a Sony STOCK FTF if you are currently on a custom ROM-
Steps:
1) Download Flashtool. Start Flashtool and click on BLU button
2) You will be asked to connect device in flashmode
3) Once you connect the device, you'll be prompted to "Relock"
4) Click on it, and when prompted, disconnect your Ultra

there is a new flashtool driver version too. It probably wont matter... but you could add it into the FAQ section or something. For those having issues with flashtool...

Thank you very much! I've added it under downgrading, and I also added the ADB and Fastboot Windows installer for people that have trouble installing those manually.

I didn't need to do that. I was on stock Sony build 257 and had never flashed AOSP before. All I did was root the phone, update OTA, install recovery and just flash a ROM. Looks like Sony's official unlock is unlike HTC dev unlock and doesn't need a PC (fastboot) to flash ROMs.

Yeah, it seems like it's a hit or miss with the whole boot.img. First time i tried to flash Omni (coming from 257) it wouldn't flash if i didn't flash the boot.img first, but it worked just fine after flashing it, so it seems like people have different experiences and outcomes with the whole ROM flashing, and that's why i just included it so the people that uses this guide gets to the finish line. It's a "fail safe" way of doing it.

True that. It appears (as someone mentioned) there's a problem with Omni's install script. Other ROMs flash fine from stock without the need for fastboot.
I have a Sony Xperia Tablet Z, 64GB WiFi (SPG312) running stock 4.3, and I can not root this thing. I've tried several different methods to no avail. Does anyone on here know how to root this thing? I'm ultimately trying to install CM11.
Either go back to 4.2, root with Doom's Rootkit, then install a recovery, and install 4.3 already rooted, or unlock your bootloader, install CM kernel, use the recovery built in to install the SuperUser zip, then flash stock kernel again.

So unlock the bootloader? How do I go about that? And after that I can install CM right from there? That sounds like the one thing I haven't tried.
How do I go about doing that?
http://unlockbootloader.sonymobile.com
Follow that link. It's pretty easy. Just make sure you have all the tools in hand. Shouldn't take more than a hour to read everything and do the procedure, if you have everything ready.
It's mentioned there, but remember that it will void your warranty and, with Android 4.3 or lower, on stock ROMs, you will not have Bravia Engine working. Also, in any version, Music and Video Unlimited will not work anymore.
Another big tip: Go to the Xperia Z section (the phone one), and on the sub categories, can enter one called Cross Device Development, or something along those lines, and look for a thread with the name TA backup. If you do the long process, of going back and such, backup your keys. Should come in handy in the future.

u need to download flashtool and find a 4.1.2 rom for your device...
then you can either use framaroot 1.91(gandalf exploit) or use doomlords root setup...
after that you can install phill'z recovery...
http://forum.xda-developers.com/showthread.php?t=928343 this link was very help full for my device sgp311 and i think its almost the same for your device only the rom and the stripped .ftf will be different...
unlocking your boatloader is not really applied to you,you only need it if you want to install custom roms...but before you do search a bit around to find hou you can backup your drm keys aka .ta partition.
Make sure you downgrade to 4.2 and root using http://nut.xperia-files.com/?dlid=V...jb3ZlcnkyLjcuMTIzLUJFVEEuaW5zdGFsbGVyLnppcA== option 3 then backup your TA partition before unlocking your bootloader, or theoretically you'll lose warranty
ok ok ok
So what steps do I take to install CM11?
Which method posted would get me there? You guys are saying a lot of different things here, have me a little confused
Hi anyone knows and tries this Kingo to root and unlock bootloader

thanks
Unlock bootloader > flash any cm10-11 kernel that has recovery built in > boot to recovery > flash SuperSU > flash 4.4.2 stock kernel back (from FTF)
So today I managed to root my Z2
Following advice from o0 Matt 0o in another thread, I downgraded from 4.4.4 to 4.42 using flashtool, then using the rootkitXperia_20140719 install.bat the phone is now rooted (for some reason it would not find adb even though running adb from a cmd prompt worked!)
Anyway, now I am on 4.4.2 with root, if I upgrade back to stock 4.4.4 rom will I lose the root?
EDIT: I have installed dual recovery, is there a pre packaged rooted rom for:
Android 4.4.4
23.0.1.A.0.167
United Kingdom - 3 - 1281-2574

Dont really want to create a rooted package myself, the steps can be confusing
Thanks!
Since you have dual recovery on 4.4.2 you can use the pre-rooted package by niaboc79 (can be found in the Android Development section) or any pre-rooted stock based ROM based on 4.4.4. It is all down to your preference.
I doubt there will be a 3 branded pre-rooted package either.
Actually you're right I should just get one of those roms which is not branded which would look better anyway
One last thing what is the steps to backup ta partition? At some point I will unlock bootloader but don't want to lose the dry keys
Cheers

In the Sony cross device development section there is the backup TA tool, simply use that. Also, make sure to upload your backup to a cloud service or something like that, in case your hard drive goes kaput and you need it to relock your bootloader.
Please remember that unlocking the bootloader wipes the internal SD card (not the user one). Also, restoring the TA backup relocks the bootloader so make sure you are on a stock ROM and kernel when you restore the backup.

Cool thanks for the tips :good:
I have done: revert to lollipop, root, install recovery (NUT's dualrecovery), flashed eXistenz (3.5.0)
And I would like to get a working recovery.
current state
ROM: 6.0.x Marshmallow based eXistenz with root access, version 3.5.0
Bootloader: locked (would like to keep it that way, because warranty)
Recovery: none? (tried 'adb reboot recovery', various volume/power key combinations and some apps from market)
my questions
1. I've heard that NUT's dualrecovery won't work on Marshmallow, so which one will?
2. Is it even possible to have recovery on marshmallow rom without unlocking bootloader?
3. If I unlock bootloader is it possible to relock it? (I have TA partition backed up)
4. Why do some roms require unlocked bootloader, but some work with the locked one?
Thanks
1. That's true, NUT's dualrecovery works on lollipop, but not on marshmallow and trying to install it will get you into a bootloop.
2. It's possible, since serajr was kind enough to make it for us. You can download it here.
3. We're almost sure that backing up your TA partition (and restoring it if you need to) will get you your warranty back. Just make sure you downloaded the right version that works on marshmallow and dry-run the backup to be sure it successfully backed it up.
4. Some roms have features that require custom kernel, and to have to unlock your bootloader to be able to replace stock Sony kernel with a custom one.
Hope that helps you understand your phone a little better [emoji57]
Thanks

Thanks for help
I've had a Nexus before and it was much easier with it
Praise serajr, I have a working recovery now
Yup, I'm sure it's much less complicated and easer to customize.
Anyways, I hope you will be happy with your Sony [emoji2]
