Had root on 4.4.2 but lost root after updating to 4.4.4? Any suggestions?
Sir,
Please wait until mods will move this thread to the device specific forum.
For reply or more questions please register an account on XDA forums.
Stand by
Good luck
since there is no root exploit for 4.4.4 , you have to downgrade to 4.4.2 (flash ftf with flashtool) --> root it --> install recovery for locked bootloader and then flash any pre-rooted 4.4.4 rom by recovery.
OR
You can also root 4.4.4 directly by unlocking your bootloader --> flash recovery --> flash supersu but you'll lose DRM keys and some functionality on the phone.
You can find tutorials for both options here, search a little.
Is there a way to root my Xperia Z2 (4.4.4) without unlock its bootloader?
Or else better, is there a way to back-up the bootloader before the unlock?
I ask because I want to root it without set a custom Rom.
Thanks in advance.
There is. You've got to downgrade to for example 4.4.2, root your phone, create a pre-rooted version of 4.4.4 and then flash that. There is a much more detailed guide around here, so I recommend that you check that out
To back up your ta partition you will need root first.
In stead of creating a rooted rom you can also find some prerooted here in the development forum.
-Use flashtool to downgrade to 4.4.2
-Root and install recovery with one of the available root methods (towelroot for example)
-Use recovery to flash a rooted 4.4.4 zip, recovery (again) and SU (again)
-Reboot
-Test network connection, if 4g is not working, use flashtool to flash a local 4.4.4 baseband
That's all.
I heard that for rooting it's required to have unlocked bootloader. Is that true?
(I have seen the root guide in forum, but I don't think that it mentions the bootloader)
My problem is that I want to upgrade the phone without errors (when sony has updates). I say that because a friend of mine has a rooted Nexus 5 with unlocked bootloader and he can't install the last update.It gives him a bootloop and returns to the previous. This is something I don't want.
Thanks in advance.
Unlucking is not needed.
Official updates should work if you're on a 100% stock rom, but updates are generally available as flashable rooted zip, here in the forums, long before you get an official update available from Sony.
So that should be no problem.
Biggest issue here that people dont search howto root on locked bl, that is possible, search and read then you will have it, example like the installations steps of a modded stock rom

Hi,
I just want to install a custom rom for my z2 but i'm having a little bit of trouble figuring out how to install it.
I was interested in installing the resurrection remix rom found here http://forum.xda-developers.com/xperia-z2/development/rom-resurrection-remix-t3028260
I'm currently on the official 5.0.2 version of android. I upgraded from 4.4.4 to 5.0.2 through Xperiafirm.
As far as I understand you need to have both root, an unlocked bootloader and a custom recovery to install a custom rom. NOTE: I have met none of these requirements.
My problem is I cant find a way to root my z2 on 5.0.2 or unlock the bootloader for that matter.
From what I gather most people upgraded from 4.4.2/4.4.4 using a rooted z2 to a 5.0.2 pre-rooted rom to keep there root permissions.
Does this mean I'll have to downgrade back to 4.4.2 or 4.4.4 and then do one of the easy root processes then flash the custom rom?
Or is there an easy way to root and unlock my bootloader on my z2 on 5.0.2 so I can flash the custom rom?
Thanks in advance for the help guys.

Since you haven't rooted Lollipop theres no easy root method.
1. Use flashtool and flash any 4.4.2 (17.1.2.A.0.314) from here
2. Then root and install recovery in one step using this guide :
+Make sure you have USB debugging turned ON and plug the phone to your computer.
+Download Z2-lockeddualrecovery[VERSION]-BETA.installer.zip from http://nut.xperia-files.com/?+Download=qh1p4ekeofo9krfbu6maic2np5&randomizer=_mc6cojzeq
+Unpack at C: or somewhere you will remember!
+Navigate to the resulting directory and look for install.bat, double click it to run;
+Select "Installation on Unrooted rom....." option
+Your phone WILL reboot when installation has completed and it will go into the default recovery for the first boot.
+Reboot to system from recovery to allow the installer to clean up after installation (it is safe to skip this step).
3. Once you have recovery installed you will hve to unlock the bootloader. Since unlocking the boot loader will remove your DRM keys you have to back them up first. Use this guide to backup DRM keys and then unlock the bootloader using this (read the whole forum carefully).
4. Since you have unloacked the boot loader you an proceed to flash and rom according to the instructions through the recovery.
Hi
Could somebody guide me, because I'm a little confuse looking through the forum.
I want to upgrade my tablet with custom ROM (CM 12 Nightly ROM).
My tablet has unlocked bootloader; build nr: 23.0.1.A.0.167, and kernel version: 3.4.0-perf-gd4d661a
I’d like to know, how to root my tablet;
How To Install A Custom Recovery;
How to flash CM 12 Nightly ROM.
Could anybody show me the links where can I find all this solution.
Since your bootloader is unlocked flash the advanced stock kernel and flash advanced stock kernel http://forum.xda-developers.com/showthread.php?p=57192065
You can flash root script and dual recovery to have an updated recovery. Then flash cm 12.

I also want to root my SGP611, but I don't need a custom ROM. How can I achieve this?
And should I leave my bootloader locked or not? Because after reading some threads here, I have the feeling that either you
1. Flash rootable system image; then root via giefrootv then backup ta; then flash back original firmware; then unlock via Sony's official method; then somehow some more confusing steps to gain root
Or
2. I skip unlocking bootloader (DMR keys unharmed) , but what should I do to gain root access? Does giefroot (exploit) work with Kk (4.4.4)? Didn't somebody say that the exploit is already patched? And what about the xdualrecovery thing? It didn't mention that it's compatible with SGP611...
Hey all, first of all I'm not new to the Android world. I've had many phones, and all if them modified heavily. I do not consider myself a Dev (I've made some basic scripts that's about all) but definitely a power user.
Anyway, I'm a little lost on this z2 as far as modding it goes. My bootloader is NOT unlockable according to the phone stats, however I have seen a few root methods for 5.1.1 and locked bootloaders (I'm build a.1.232). Now many of these rooting methods ask for you to downgrade to a rootable version, root it, then reflash a prerooted 5.xx ROM. Easy, However with my unlockable bootloader how will I flash anything other than a stock Sony ROM without bricking it?
Essentially what I'm after is how far can I go with a locked bootloader, and if there is s surefire way to root 5.1.1 without downgrading since I can't flash back up. Also am I good to flash a custom recovery? Or is that offlimits as well being locked. I'm a little lost due to lots of mods here apparently working with locked bootloaders, and on my HTC one that just didn't fly.. Lol.
Thank

You meant locked bootloader right?
You won't be able to flash any custom ROMs without unlocking your bootloader.
The only custom ROM that works for locked bootloader is MIUI (which uses the stock Sony kernel)and the phone needs to be downgraded to 4.4.4 and there are some custom ROMs out there which may work on locked bootloaders.
Yes,you will be able to flash custom recovery and use mods that are available on XDA and also xposed works fine on LB
You won't be able to flash custom kernel or custom ROM for LB
Yes downgrade is possible
