Hi, everyone, I just got my z3 tablet and I am in love with it except i don't like the interface. So i decide to root my tablet without unlocking the bolted and I did made it and i did install TWRP. I have a question, since I have TWRP is it possible for me to install cm 12 rom or I need to have a unlock boot loader in order to install it?
Sorry for my bad english and thank you for answering my questions.

You need to unlock to flash a custom kernel which would be needed by the cm12 to run. So first.
1.Backup drm keys
2.Unlock BL
3. Flash CM kernel via fastboot
4. Flash CM Rom via recovery.

I just bought a Z3 tablet compact, which should be here at the end of next week. I haven’t found a tutorial which includes all steps to get from the standard rom to CM12. Did I miss any steps or does the following steps include everything?
Root tablet on the original Sony rom
Backup TA partition (I guess that's where the DRM keys are?)
Unlock bootloader
Flash a recovery (any recommendations?) I found this tutorial, but I only need one recovery and I don’t want to flash that zip every time I install a new rom.
Flash CM12. Are there any kernels beside that one included in the CM12 zips?

I guess you should just flash the kernel via fastboot after unlocking the bootloader, that would eliminate the need to flash a recovery. It's hitting 2 birds and one stone and besides CM uses a different kernel than stock so later you would really need to flash kernel.

Thanks for your reply. The whole flashing procedure is a lot more complicated than on my S3, so I have a follow-up question.
Should I just backup the TA partition, unlock the tablet, flash this kernel which should give me root and TWRP and then flash another recovery and CM12?
I found this recovery which is only semi-permanent, because you have to flash it before you upgrade/install a new CM12 version. It’s not big deal tbh, but is there a permanent recovery, which I only have to install once.
I'm also curious about this.
Right now, I'm trying to download the Flashtool program from Sony, but apparently, you need to "register" for it. Where did you guys download your Flashtool from?

Correct, make sure the kernel is compatible with CM

The whole procedure is really frustrating, maybe someone can help me here.
I did a backup of the TA partition and unlocked the bootloader. I tried flashing the boot.img from the cm.zip, but I have no idea how to flash the rom via the cm-recovery.
Flashing the advanced kernel to get TWRP wasn’t successful as well. I tried the fastboot mode of the Flashtool and flashed the kernel, but nothing changed.
Can someone post a brief guide with the next steps to get CM12 running (with cmd commands pls)?
EDIT: I just tried to use “adb sideload” in the CM recover, but “adb devices” doesn’t show the tablet .
EDIT2: EDIT: Seems like I got it to work after all. The DualRecover Installer worked, even without SuperSU installed.

I ran into the same problem usin the cm12 nightlies from 27th march 2015:
Sideloading would not work because the tablet is not recognized by the computer. I tried with Windows 7 and gentoo Linux.
Installing from the sd-card in recovery mode was also not possible due to a error of missing "/misc".
I solved the problem by manually choosing the driver in Windows 7. I booted the tablet into recovery. Choose update using adb as detailed in this post:
http://forum.xda-developers.com/z3-...t/root-root-locked-bootloader-sgp621-t3013534
Then I found the device in the windows device manager. Here I manually choose the adb driver that I installed earlier from the flashtool package. After that the device was correctly recognized by Windows and I could Sideloade the cm12 image.
I just installed Cyanogenmod and whenever I boot into Cyanogen recovery and try to apply an update it fails. For example I tried installing the flashable .zip for NUT’s DualRecovery but got
Finding update package...
Opening update package…
Verifying update package…
E:footer is wrong
E:signature verification failed
Installation aborted.
same happens with a boot animation. By the way I have an unlocked bootloader.

I'm going to need some help on with this. I tried ">fastboot flash recovery twrp-2.8.6.0-sirius.img" and it put the device into a bootloop.
I got it to work. Using Rashr I installed TWRP.

After installing the NUT’s DualRecovery, TWRP thought my phone was tianchi ( Sony Xperia T2 Ultra ).
I got Cyanogenmod working at last ( by flashing the boot.img inside the zip ), Everything seems to work fine for me. I even flashed CM 12.1 unofficial port by infected_. It still works fine for me... Try flashing the boot.img again and see if it works.. Also have you flashed other kernels or mods?

Zu is not included yet. This is what HTC has been doing for ages. Not sure why everyone does it this way...
There are two rules in life for being successful:
1. Never reveal everything you know;
2.
Sony has now made these available for a variety of Xperia devices, including the Rhine family (which the Z Ultra is). Excellent news! Thank you, Sony ❤
Would this new bootloader brick the Z Ultra GPE?
ZU is now supported but I tried flashing it today over stock 5.0.2. Foraging showed as successful but nothing happens when I try to boot into recovery. The phone just reboots normally
What benefits is thing going to offer over what we previously had? Trying to figure out if I should wait with anticipation or apathy.

most likely it will brick your gpe. And you don't need this "new" boot loader, Gpe has all the features already. It's just Sony devices had the function removed.
This boot loader allows booting directly to recovery without having to go through the boot partition. GPE doesn't let you do that right?

As far as I can tell, only c6833 is supported so far.
But if you wanna give it a try, head over to sonymobile.com/developer. you have to install the Sony flash tool for xperia devices.
when you open the flash tool and connect your device as instructed on the website, it will show all the available 'services' you can flash to your device.
Have you guys succeeded in booting to recovery? Coz I have flashed TWRP to recovery partition and it doesn't boot
Regards
Would be interesting if the GPe stock firmware can be flashed after this, since GPe and the normal ZU are more euqal than ever with that.
Anyone tried to flash stock GPE after this flash ?
Since a lot of you guys seem to not get into recovery after installing the new sony bootloader i might share how i succesfully did it...
I've installed the new Sony-Bootloader (or how Sony calls it "TA-Update") on my Z-Ultra (C6833)
After that i immediatly booted into fastboot and flashed twrp to the recovery partition (fastboot flash recovery FILENAME)
Succesfully booted into the twrp-recovery version i flashed
Device didn't got wiped, but cache partition did get wiped
But i was running twrp-recovery (but im pretty sure it wasn't the newst version) before on fotakernel, also i was running aicp-rom
Didn't do any experiments afterwards, but we'll see what happens after i flash a new rom

Didn't work for me. Did the same but it didn't boot to recovery, it booted up normally. I had twrp installed in FOTA, too.
I flashed in a virtual machine with Windows Vista since I wasn't able to get Emma running in my Windows 10 x64 Pro.

Flashing stock 14.6.A.0.368 installed the recovery partition for me. (C6806, which Emma is still to provide me with the partition)
The trick is to actually find a recovery that is written to work in the recovery partition, Saatvik Shukla has posted a build of TWRP over in the developement forum which works. The "Official" version over at twrp.me doesn't

Thanks man, I searched for something like that but didn't found that. That explains why it didn't boot the recovery. I'll try that later.

I accidentally flashed TWRP to the boot instead of recovery. Whenever I turn on the phone it goes straight to TWRP. As it stands the phone is unsuable! AS far I understand it the way to fix this is to flash the phone's original boot.img to the boot. Is this correct? If so my phone is MT2L03 with the 5.1 update. Does anynone know of any link or could anyone PLEASE share their stock boot.img with me. I really need help!
Thank You.
Boot image is part of OS. If you want to install CM12, while you are in twrp, just transfer the cm12 rom and gapp from pc to your sdcard, then flash both. You get complete cm12 with its boot image.
But if you want stock boot image back, you can just flash the stock firmware using the 3 button boot. It is available in the "official stock firmware" section in the INDEX page: http://forum.xda-developers.com/showthread.php?t=3149530
If you have difficulties doing that, let us know. I maybe can find it somewhere, but to be honest, I don't use stock anymore once CM is out.
Thanks. CM12 flash problem
I was able to find a b321 boot.img online so problem solved. The cm 12 flash is not working for me I keep getting an error while flashing TWRP keeps telling me that the cm 12.1mt2 file is specifically for the b322 bootloader but that my bootloader is "unknown" so its unable to flash.
Still haven't figured out what the problem is. I tried to install the specific 2.8.7.0 TWRP for the mt2l03 via the app but it gives me an error. When I try to flash it in recovery it still has no effect on the cm install. Maybe someone would be kind enough to guide me.

Try reading the OP for that ROM. It clearly states you have to be in b322.... Reading is key.

i do have b322. So the problem is not that. the problem was already there even before i booted with the b321.img. In any case the img is for boot only. It is not the build.
Also twrp, have you install the twrp listed in that same page? other twrp version doesn't work.
Edit, saw you mentioned already that install twrp error using app. So try install the correct twrp in bootloader.

You need to put the Customization.ini file in Emma's folder prior to running, as per the instructions. Then it won't need a login.

You should already have the new recovery, it will have been installed/ partitioned when you first installed Stock 5.1.1. (The method described in the link above or even using Emma does not work on C6806 by the way.)
It does require an unlocked bootloader for it to be active though.
-------------------------------------------------------------
Doesn't work on my C6806, device just continues to boot the OS.
I have the recovery partition as I can access championswimmer's build of CWM or Saatvik Shukla's build of TWRP 2.8.5.0 if flashed into recovery. (and a build of TWRP-2.8.7.0 that I forgot that I had downloaded from somewhere in December)

I know, I can flash into the recovery partition (and access) three different recoveries, See my previous post.
@pTeronaut sorry didn't read that

There is an "issue" with the fstab and recovery.init.rc script with this recovery.
I just built crDroid-mm, and the mountpoints of the "new" install scripts don't work with this build of twrp, since there is a missing symlink (github commit)
If any1s interested, i've gone ahead and also built twrp 3.0.0 for our togari
How can I check if I have new partition for recovery? I flashed with flashtool .216 firmware a month ago. Now I have gpe port with recovery in kernel. Is possible to have recovery in kernel (old recovery) and in the same time new recovery?
If You flashed/updated to newest fw at least once You have new bootloader with /recovery.

You can also use the Emma Bootloader and flash it into recovery via:
Code:

fastboot reboot
But this way needs UB

Emma doesn't find any 'services' for C6806 (NA LTE ) & C6843 (Brazil with OTA TV) variants.
An update on my attempt to get TWRP 3.0.0.0 installed and working on my C6806.
My previous attempt was coming from flashing stock roms from 5.0 onwards using Flashtool or PC companion.
This time, I relocked the bootloader & flashed the FTF of 14.3.A.0.681 (4.4.2) and let my phone update itself all the way to 14.6.A.1.236, re-unlocked the bootloader, and tried to flash TWRP again.
This time I was successful, either Flashtool and/or PC companion cannot handle the repartitioning, or they mispartitioned my phone the last time around.
