[Q] A small question about flashing cm 12 - Xperia Z3 Tablet Compact Q&A, Help & Troubleshooti

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.

[Q] Root Xperia with Lollipop?

Hi, I'm kind of a noob, so sorry if this is a dumb question.
I just installed the new Lollipop Fimware on my Z2, using Flashtool. Now I want to root the device, but reading through articles on XDA or XperiaBlog, they all said you need to use older firmware. So my question is, can you root the Z2 with Lollipop?
I'd be grateful for helpful answers.

Things needed:
PC, fastboot driver, know how to boot to bootloader(fastboot mode) and recovery mode
Now you can without having old kernel (not firmware)
go to http://forum.xda-developers.com/xperia-z2/development/kernel-andropluskernel-v10-t2974841 extract boot.img from the zip file.
Boot your phone to fastboot mode and in command:
Code:
fastboot flash boot boot.img
Go to recovery mode after restarting and then get UPDATE-SuperSU-v2.46.zip and flash it via newly installed TWRP recovery.

Same here. I'm a noob wanting to learn how to root. But this went over my head :/
Would using PRF creator work? If you bundled the lollipop firmware with supersu.zip and flashed it would it give you lolipop with root? Because this is what i did to update to 4.4.4 with root. For anyone that doesnt know PRF creator is a program which combines 3 files which is are firmware of your choice, a superSU.zip and a recovery.zip. It combines them into a .zip that you can flash in recovery and have the firmware with superSU and a custom recovery on it.
I have a locked bootloader and mines rooted, do you want me to say how?
If its on lollipop, i would very much like to know how.
Isn't this the exact same answer as rooting 4.4.4?
Downgrade to 4.4.2
Root
Install recovery
Install rooted lollipop zip in recovery
If you don't understand this or the method posted above don't root. Also, if.you can't google things like fastboot to understand what it is don't root.

Bootloop
Everything was fine, till i tried superSU. Twrp flashed it fine, but then when i tried to reboot, the device got stuck in a bootloop.
wipe cache/delvik also didnt help.
I have a new z2, then unlocked the bootloader, and then got the Norway rom using xperifirm.
Norway rom installed fine. twrp installed fine. But i am facing a bootloop now that i have flashed UPDATE-SuperSU-v2.46.zip
Anybody else face this issue?

try wiping just "Dalvik Cache" and restart again. I have also face similar strange issue when I was using FlashTool a couple of times.
If that doesn't work try normal wiping from TWRP and install firmware using FlashTool.

I'm no Android/Lollipop/Rooting expert but using an unlocked boot loader I was able to root Lollipop (23.1.A.0.690 ) easily using the kernel from:
http://forum.xda-developers.com/xpe...ot-stock-flashable-kernel-23-1-0-690-t3061816
My steps were:
1. Install Lollipop
2. fastboot flash boot boot.img (to install above mentioned kernel with TWRP recovery)
So far so good.
PS: To use fastboot you'll likely need the drivers from flashtool (http://www.flashtool.net/index.php) and if on Win 8.1 you'll need to search for instructions on how to install unsigned drivers.

[GUIDE] (C6833) (Maybe Others?) New Bootloader + Recovery

Installing the new Sony Bootloader and Recovery
THIS IS FOR ALREADY UNLOCKED DEVICES!
DO NOT TRY THIS ON A GPE!​Since a lot of people seem to have problems keeping their recovery when flashing Lollipop-ROMs i decided to put up this little guide...
You can also Skip this whole guide, by just flashing the newest stock-FW at least once!
First off, as already said, this is for already unlocked devices. You can use this Guide until "Install Custom ROM", except the rooting part, for rooting use this, if you haven't already!
Don't do it if you don't atleast somewhat know what you are doing.
I am not responsible for bricked devices, or whatever you might end up with.
So, lets get started.
1. Download Sonys FlashTool "EMMA" and install it: http://developer.sonymobile.com/downloads/tool/flash-tool-for-xperia-devices/
In the .zip file from the FlashTool you'll find a File "customization.ini"
Copy this file to the installation directory of EMMA, usually "C:\Program Files (x86)\Sony Mobile\Emma"
If you don't copy that file, Emma will ask you for a login, don't create an account there, you will NEVER get any activation-email!
2. Open EMMA and boot your Phone into FlashMode (Power off your device -> Press and hold volume DOWN -> while pressing volume DOWN insert USB-Cable)
3. Emma should now recognize your device, but you have to select it manually tough. Select your EXACT model number. Again, I am not responsible for any bricked devices or whatever you end up with!
Now select the "(Open Devices) TA update" and click "Apply Service"
It should take a few seconds and should then display SUCCESS.
You can now close Emma
4. If you haven't already download FastBoot and Drivers: http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
(Run as Administrator!)
5. Download the newest version of twrp and put it somewhere:
New Inoffcial twrp-3.0.0 build by me: http://forum.xda-developers.com/xperia-z-ultra/development/togari-twrp-recovery-3-0-0-t3314440
Old official versions: https://twrp.me/devices/sonyxperiazultra.html
6. Finally boot up you Phone in FastBoot-mode (Power off -> press and hold volume UP -> while pressing wolume UP insert USB-Cable
Your LED should now light up blue
Shift+Rightklick in the Folder where you have put TWRP recovery, and select "Open Commandprompt here"
Now write "fastboot flash recovery FILENAME_OF_TWRP_FILE"
You can now unplug your USB-Cable and boot into recovery and continue from there.
Your recovery will be permanent, meaning you won't loose it or replace with any other recovery that might come with your ROM.
I hope this was somewhat helpfull

You can try, just select your modelnumber in emma
If the "Open Devices (TA Update)" show up, you're fine. If not just don't do anything.
But do not try this on a GPE!

tried, but no luck. thanks.
It's really weird, I used emma, and installed their latest ta update. Now I can get into fastboot mode, all commands execute successfully, but the recovery never takes. The vol down + Power doesn't work, nor does 'adb reboot recovery'. Am I missing a step somewhere? This isn't my first android device, but from where I sit, it seems like something is up with my xzu.
If I try and install the 14.4* update through emma, it goes through the whole process, completes "successfully", then boots into 14.5. Something is clearly not working here.
The TA update only unlocks the ability to boot to recovery, it doesn't install one. And no, flashing official TWRP to recovery partition doesn't work, it must be compiled again to work on normal recovery partition and not in FOTAKernel, where it must be flashed to work.
Regards

I´m on CM 11 M12 (looking forward to 12) + the new sony bootloader without any custom Kernel stuff.
Sadly, you are right. It´s not done with downloading twrp-2.8.5.0-togari.img and fastboot flash recovery yourfile.img.
The last offical TWRP release for Xperia Z Ultra is from february 2015, any chance they release an updated version for the new Sony bootloader?

Is there any (wish for TWRP) recovery for togari, which use the new bootoader?
FYI:
My device is a brazilian c6843.
Emma recognizes the device automatically and indicates with an exclamation point that there is no services available to the unit.
In the case someone doesn't know, it's basically the c6833 with DTV 1seg. It's totally compatible with c6833 firmware, losing TV, of course.
You sir are the real hero! Thank you!
I have a xzu running cm12.1, and I have 2 quick questions for those with more knowledge than me
Is it possible to flash the new bootloder using the open source FlashTool?
If I have to use emma, is it possible to just apply the open device ta update *without* installing stock firmware first?

You can totally do that, BUT, the newest stock firmware also has some firmware updates regarding nfc, also having the newest stock rom flashed at least once will be kind of a requirement to get everything properly working on marshmallow roms.
So I would say flash the newest stock rom at least once!

I followed your advice, but it seems I am missing a few clues.
My sirius was on cm12.1. I backedup and flashed D6543_23.4.A.1.232_1281-5466_R6C.ftf with flashtool on linux. I tried to use emma (several times) afterwards to check for any TA updates, but all I got was "no services matched this device" or something like that. Google tells me I am not the only one with this issue with emma
Then I used fastboot to install twrp 3 from twrp.me to recovery partition, but I could not access twrp.
I fastbooted recovery again with twrp 2.8.7, and this time I could enter twrp and reflashed CM.
Now I can access twrp using the button combinations while booting, but rebooting to recovery from CM leads to a bootloop. Has anyone experienced this as well?
So it seems I am still missing a few clues to using the recovery partition. Is any build of twrp supposed to work on both FOTAkernel and recovery partitions?
Is there a TWRP 3 build that works from 'coldboot to recovery' and 'cm reboot to recovery' with the new bootloader? Any pointers?

Well, booting to recovery on separate partition from os, requires the rom to have a patch... the "new" mm-roms (when they finally hit aka. are ready to be shared in public) will have that, so no worry, just wait.

Any recovery we can use for Marshmallow?

XZ Dual Recovery is not yet compatible with Marshmallow and because of this I was forced to unlock the BL. Are there any recovery that we can use as of this moment? It seems that the development section for this is not so active.

I saw that there is a prerooted 6.0.1 with only TWRP recovery installed, not dualrecovery. Can you guide me on steps to get from official 6.0.1 to root status on an unlocked bootloader? I can't do anything to go back to previous firmwares and it seems I have to unlock as the only way to get anywhere.

I tried flashing the TWRP from the site of TWRP but it results in blank screen. Also XZDR is not compatible with Marshmallow.
Did you already backup your TA? You can only do this by obtaining root so it is a must to flash previous FW (KK or LP) then root and backup your TA partion unless you don't care for your DRM keys.
1. Go to http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/ and follow instructions to unlock your bootloader. Alternatively you can use flashtool (just search here in the forums).
2. Download a TWRP image of Scorpion Windy (Z3 Tablet Wifi) https://twrp.me/devices/sonyxperiaz3tabetcompact.html
3. Download older versions of SuperSU. Systemless root doesn't seem to work with Xperia Stock so you go the system way, older versions are preferred. Will attach the zip I used.
3. Flash MM FW by Flashtool, do initial setup.
4. Boot into fastboot, fastboot the TWRP image you downloaded. Reboot and you should be in recovery
5. Flash the SuperSU. Flash also the RIC defeat zip. Reboot and you'll notice your just in TWRP.
6. Force shutdown.
7. Open flashtool flash the mM FW but only kernel and the FotaKernel, dont wipe anything. Reboot. It should start.
That worked for me.
After you, need to install busybox from playstore and the SELinux Changer app
P.s I can't attach any file however you can find everything i mentioned (Zips) here at XDA and TWRP. I still need to enable init.d but I guess that's difficult with stock rom stock kernel. Oh, and you can install flashfire in substitute of your recovery. Be careful with flashing Zips after you have a stable system since you don't have recovery and therefore no Nandroid backup

After you, need to install busybox from playstore and the SELinux Changer app
P.s I can't attach any file however you can find everything i mentioned (Zips) here at XDA and TWRP. I still need to enable init.d but I guess that's difficult with stock rom stock kernel. Oh, and you can install flashfire in substitute of your recovery. Be careful with flashing Zips after you have a stable system since you don't have recovery and therefore no Nandroid backup

Well then, I knew what I should have done before I lost root. In any case, what certain DRM keys would I be losing on the tablet? I know the biggest commotion on the phones were the camera algorithms.

You would lose camera algorithm (I don't care for that, it's a tablet and its pictures are bad from the start).
X-reality and display enhancements, sound and noise cancellation (This is i don't want to lose since i use mine mainly for graphic projects) and remote play. That's only what I remember, i don't know if I missed out something.
NO NEED TO UNLOCK THE BT, flash a MM prerooted zip you can make it yourself with prf you need the FTF, recroot and superSu.
Anyway if you still want unlock the bt backup the drm keys with backupta

That won't work and would cause bootloop. tried the latest supersu. anyway, i found the workaround and it's been working good now.

Wow, yeah that's too dire for me to go forward to. I should've just stayed on lollipop since it was already what was best for me.

Flashing a ROM

Hello,
I started on a quest last week to try and make my long forgotten Xperia tablet z LTE SGP321 more user friendly.
I stopped using it after being frustrated by the bloatware and its lack of customisation.
So I thought flashing a custom rom might help and wanted a bit of a technological challenge. Boy do I feel like I've got one.
I used kingroot, which worked fine. I tried to install SuperSu but it wont update the binaries.
I've managed to unlock the bootloader (forgot to do the backup TA woops!).
I downloaded TWRP app, flashed pollux_windy to recovery. Now there doesn't seem to be a combination of keys that I can find to boot the sony xperia tablet Z into recovery?? Power and volume up or down or jamming both keys...nothing seems to work. I've found one forum post suggesting it isnt possible and that I need to flash a kernel which is where I'm getting stuck.
SO this is where I am now and was wondering if I should use CWM instead or if there is another way to open recovery?
My main aim is to completely clear the tablet hard drive and start again with a custom rom.
Thanks!
>>>>>>
NEW info
So i've managed to use the ADB to reboot into the boatloader. All that happens is a black screen. I want to try and flash CWM or TWRM but it doesnt seem to work.
Im beginning to think there's something strange about the sony xperia tablet z in that it doesnt have a bootloader in its stock firmware. i've seen something about using a Kernel approach but the guides are unclear.
Any help on flashing a CWM or TWRM into recovery would be much appreciated!!

Thanks for your help. I thought I'd start simple and just try and flash TWRP to recovery.
i downloaded the latest TWRP pollux windy img and then used the command fastboot flash recovery twrp.img
It says FAILED (remote: command not allowed)
adb fastboot devices displays my tablet
(by the way in configuration in service info it says bootloader unlocked: Yes)
>>>>>>UPDATE
so i managed to flash a cyanogenmod img using "fastboot flash boot boot.img"
The device then soft bricked and went into a boot loop. Is this because I used the wrong version of cyanogenmod?? Any other I can try that work?
I panicked a bit, mamanged to get the tablet into fastboot somehow andthen flashed a TWRM img to the boot using the same command above which now loads TWRM.
fastboot reboot now caused the device to go into TWRP but its in recovery mood
How can i undo that step i did when I flashed the boot img of the cyanogen mod. I want to put the old boot.img back!

also can I ask another quick question of you, what do you do to boot into recovery on your xperia tablet Z device?
Thanks!
Sorry about all the updates.
I decided to see what you had installed on your signature and tried resurrection remix. Version 5.8 caused Error 7??
So i went for version 6.9 which i installed successfully.
Only way i know how to get into recovery is to use adb terminal command "adb reboot recovery"
Also before I installed resurrection remix would you recommend a complete wipe of everything or does it not really matter?
Thanks and hopefully that's me all sorted!
Use VOL+ or VOL- on boot to enter recovery.

2 way for me:
- usually you can set an "advanced reboot menu" under developer option or the ROM customization panel (depends on which ROM do you use)
- turn off your tablet, now push the power button until your screen just turn on, leave the power button and start pressing vol+ and vol- alternately until you boot into recovery

Flash Custom Rom on SGP512 unlocked Bootloader Marshmallow 6.0.1

Hey Guys,
as far as i could find out so far, you use TWRP to flash a Custom Rom from the Tablets Recovery Mode, this requires a rooted device, and to do this you flash a prerooted rom somehow, which includes TWRP already, which you then use to flash the rom you actually want on your device.
Another possibility was to flash a Kernel (with TWRP?) to get the same results...
Now I absolutely can´t find a tutorial for dummies, to do that, or find the required files.
After i found it kinda complicated to unlock the bootloader, since most of the tutorials didn´t even mention you need advanced mode and a special Google USB Driver from Sony´s Developer Page, to even get that working, i would really appreciate if someone could give me a step by step with links.
If a tutorial exists, pls give me a link as well, cause i looked the whole day yesterday, and found jack.
cheers
yes, you need to do all that. i just went through this yesterday and used this tutorial:
https://forum.xda-developers.com/showthread.php?t=2747676
once you are unlocked, follow the instructions for your rom, usually to flash the boot and recovery images with fastboot. two things to watch out for though, if you are using an oreo rom make sure your twrp version is 3.2 or better, secondly, if twrp give an error where it cant mount the partitions to wipe them use the change format option under wipe/advance to change to ext4 (which essentially re-formats the partition) and you should be good to flash the rom after that.
here is another tutorial to help get adb, fastboot, and the drivers up and going:
https://forum.xda-developers.com/showthread.php?t=2588979
answer yes to everything, i can't remember if i loaded in sony specific driver on top of that or not.
goodluck!
