So I have rooted my Sony Xperia Z (C6602) using the recent easy rooting toolkit relaesed by xda developer DoomLord. However I do not know how to install a custom recovery. Can anyone help me? Also bootloader is locked in my phone. I want to unlock the bootloader. Basically I first want to install a custom recovery so that I could make a backup of my phone via Nandroid.
Thanx in advance.
Read the stickys or the Recovery threads where its already been explained.
From me to you.
1stly i have 4.4.2 (.757) running on my z1 and i downgraded to .534 and i rooted the device by vroot and backed up the DRM keys successfully.. and then i flashed to .290 and unlocked the bootloader by flashtool and then downgraded to .534 and then installed the dual recovery and then flashed using the flashable recovery using recovery and then i found that camera is not working properly.. camera is opening and when i press the shutter butter its trying to focus the area and after focusing it freezes and doesn't shutter... so this is my problem... please help...
So much fail.
Do not use vroot, it sends your imei number to an ip address in China.
Also, unlocking your bootloader on 4.2 will break your camera, it clearly says so on the Sony official site about unlocking your bootloader.
Now, the solution.
Restore your ta partition.
Use pccompanion to update to the latest firmware
Unlock your bootloader again
Flash a custom kernel of your choice
Install super user app of your choice

.534 is 4.2 FW. the camera will not work with an unlocked boot.
Follow the advice I gave above

yeah..!! i have done it.. thanks
but i have unlocked it in 4.3 does it make any sence by unlocking the bootloader in 4.3 and i didn't get any recovery mode... so.. i downgrader to 4.2 and installed the dual recovery as the thread says it needs .534 firmware to root properly...

I have to ask
Why are you unlocking your bootloader? What have you done it for? You do not get a recovery mode just by unlocking the boot, you have to flash a custom kernel with recovery in it
You either do all the downgrading and install dual recovery if you have a locked bootloader
OR
You unlock your bootloader, flash a custom kernel with recovery and install super user app
there is no need for both approaches and that's why you are getting problems

i unlocked the bootloader... i didn't find any recovery after unlocking so i followed the xzdual recovery process... but is it safe to flash a custom kernel.. and by installing only recovery without kernel does this doesn't help..

Why did you unlock the bootloader? What did you want to do with it?
You can not install a recovery without a custom kernel, xperia devices have no recovery partition, it can only be installed by pushing the ramdisks to the system partition or by flashing a custom kernel.
Please follow the advice I gave several posts ago.... that is your solution.
Then spend some time reading up on xperia device flashing.
1) Xperia devices have no factory recovery or recovery partition
2) Unlocking the bootloader is the fastest and easiest method to root and get recovery (If you are allowed to do it)
3) If you cannot or do not want to unlock the bootloader, then go through the downgrade, root, dual recovery process...

Please follow my advice from post #2
that is your solution

Greg said fifteen times - follow his guide for here.
Yoy can't flash custom kernel especially not fastboot custom kernel on locked bootloader.
Whole purpose of unlocking bootloader is to flash custom kernel.
You are confused with all this informations, I would recommend that you read few things here on XDA to understand terms and other things.
You could seriously damage your device with just one wrong step.

Hi!
I've been given a few steps on how to root, flash a recovery and backup TA on my Xperia Z1 (steps are here http://forum.xda-developers.com/xperia-z1/help/q-root-ta-backup-custom-recovery-help-t3143388 in the second post). My question is if I have to do something special to unlock the bootloader or just follow those 3 steps (1- root, 2 - flash a recovery, 3 - backup TA) and just then wipe the phone and flash a CM12.1 from the recovery? Or how can I unlock the bootloader and flash the CM12.1 on Sony Xperia Z1 (Honami)?
EDIT: !!! I found out that my Xperia Z1 says Unlock bootloader allowed: NO ! What can I do? Please?
Thank you for all of your answers!
I'm in the same boat and I have scoured the net for months and have found no solution, software or hardware or otherwise. I think we are SOL
I just received a Sony Xperia Z3+(E6533) on stock Marshmallow 6.0 and I've looked up how to root but only got ways to root while it's on Lollipop. Is there anyway for me to root on this software or downgrade from Marshmallow to Lollipop on this phone?
You can also root your phone while on MM. You can unlock the bootloader, flash a rootable kernel followed by a recovery and than flash the SuperSu zip. No problem.
But it is not recommended to do so, because you will loose the DRM keys/functionality when unlocking the bootloader. And once the keys are gone there is no way to get them back.
The better way is to downgrade to LP (e.g. .266), backup the DRM keys (TA Backup) and proceed with unlocking the bootloader and rooting the phone.
That's also the way I did yesterday, when I got the Z3+.
And of course you will have to read... a lot...
Thanks for the heads up , I've been trying to figure out ways for my specific model all morning and last night.
So to downgrade I'll just unlock the bootloader first then get a Lollipop firmware and flash using flash tool then do the other steps such as getting a rootable kernel and so on?
No, that is not what I wrote. Before unlocking the bootloader you will have to flash a LP firmware assumed that you want to backup the TA partition with the DRM keys first. This can only be done under LP.
I think you will have to read a little bit:
How to root Xperia Z3+?!
iovyroot - (temp) root tool
[Rootable Kernel SXZ3+ IVY/IVY_DSDS Marshsmellow ] [32.1.A.1.163]
What are the issues if we loose Drm keys? Will it affect non DRM normal contents? Or will it altogether disable Netflix or any other apps using Drm or other encryption?
You may have a look here:
Loss of DRM Keys or
Unlock your boot loader (Risk section)
Why don't create a guide?
Do some readings
I am completely new in the world of custom ROMs but experienced in the Linux world. I want to replace the original Android firmware of my mobile phone with LineageOS. Now I am looking for a way to be able to return to Android in case I am not satisfied with LineageOS or anything goes wrong. My idea is to plug the phone to my desktop computer (using Linux) like any other external device and mount the phone's filesystem so I can make a backup of it with the dd command. This way I could simply use that backup to overwrite LineageOS with the original Android. I have not found a howto for this procedure on the web, so I guess, my approach is not possible.
I found a few howtos that recommend ADB for this task, but the phone has to be rooted to apply ADB, so making a backup of my rooted phone would not let me return to the unrooted state, in which case the phone's warranty would be lost.
My question is: Is there an alternative way to completely backup my phone without rooting it? And if not, what would be the most simple but safe solution without depending on Windows-only software? Any advice pointing me to a solution is appreciated. Thank you.
Do you still have warranty on Xperia SP?!
1- You can Root and Unroot your phone again anytime.
2- You can Unlock and Relock your bootloader anytime.
3- The most important and the only thing you need to backup is the TA partition that has all DRM keys of your phone.
4- You have to Unlock your bootloader if you want to install Lineage OS ROM.
5- You have to backup DRM keys before unlocking your bootloader.
6- Here you are step bay step what you need to do before flashing Lineage OS ROM:
a- Root your phone using twolroot app from here
b- Backup DRM keys ( follow this guide for Linux ).
c- Download Flashtool version (0.9.18.6) for Linux from here.
d- Finally follow this old video tut to unlock your bootloader official way.
P.S: Read carefully the instructions in these links before doing anything, I am not responsible if you brick your devices.
Yes, I just bought a brand new SP with a valid warranty.
So, the only partition that is modified by the custom ROM is the TA partition?
I just noticed that my device does not allow me to unlock the bootloader. I have to find a way to achieve
Bootloader unlock allowed: Yes
Edit: Trying to boot into fastboot mode (holding volume up; connecting device to PC by USB) does not turn the LED to blue but to green, and in my PC's file manager the device does show up, but cannot be mounted
My phone is not SIM locked, so no network carrier, no contract involved. Bought it from a hardware online shop.

No, not only the TA partition but you can restore everything by re-flashing the stock rom except the DRM keys must be restored from backup.

if you have "Bootloader unlock allowed: No" then I don't think you'll be able to flash LOs Rom.. And I don't know if there's any way to make it "yes".. Sorry [emoji120]
But there's some old ROMs for locked bootloader devices here on xda just search for it if you want kitkat or lollipop or even stock based ROM.

So, these ROMs can be flashed without fastboot? How is that possible?
