Hi , I want to ask some question about flashing custom roms like cyanogen mod on xperia phones
Currently i have Xperia ray with unrooted gingerbread 2.3.4 , 4.0.A.2.0.42 firmware
I want to flash cyanogenmod 7 and my questions are --->
[1.] How can i unlock boot loaders without messing up DRM ? bcoz i heard after unlocking boo loaders update service and some apps wont work.
[2.] How to re lock boot loader in order to get warranty back ?
[3.] Will i need to root my phone in order to install CM7 because , in cyanogenmod wiki they not mentioned root, but i think i need to root my phone
If yes then can i use "Xperia 2011 Easy Rooting Toolkit" to root my phone running on gingerbread 2.3.4
http://forum.xda-developers.com/showthread.php?t=1320350
[4.] how to install full functional clockworkmod recovery on xperia ray ?
[5.] While installing cyanogen mod after flashing boot.img , will i able to make backup of my stock rom ?
and how to restore it even i bricked my phone ?
or is it possible to flash ftf firmwares anytime using flashtools, or wotan . is there any official firmware tool for sony phones ?
and how to get official firmware in FTF file format
[6.] When i successfully installed cyanogenmod , will i get all option to install another custom ROM over cyanogenmod (i.e. CWM recovery and rom manager)
No developer replied my questions , after hours of research i found answers
[1]. http://androidflip.com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working/
[2]. re-locking bootloader is not possible this time for xperia ray , sony will solve bootloaders issue very soon , then we will not need to worry about this, although we will lose warranty
[3].no need to root your phone , it is like installing ubuntu on windows without knowing passwords
[4]. fxp made CWM for ray but this time it only works with cm7 and MIUI, there are some experimental kernels with cwm are available but i dont recommend them
[5]. of course you can make complete backup of stock rom
to restore follow this = http://forum.xda-developers.com/showthread.php?t=1382088
you can also revert to stock using flashtool , follow this = http://androidflip.com/how-to-install-android-2-3-4-gingerbread-update-on-xperia-ray-st18i/
[6]. definitely you can flash any custom / stock rom over cyanogenmod
maybe u can try my tutorial, but that's language indonesian, u use google translate dude, hehehehehe....
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

i have the d6503 with android 4.4.4 build no. 23.0.1.a.0.167 , there are many tutorials but i fear from bricking my device....what is the easiest most noob friendly way to root the z2 (link please?) and can it be done without downgrading ?
Yes. It can. You have to install some recovery (like cwm) and then just flash a supersu package. Installing recovery is being best done, when your bootloader is unlocked, as doomkernel has already custom recovery installed.
If you want to unlock your bootloader follow official Sony instructions.
You will also need some flashtool to flash your first custom kernel.

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.
Basically want to root this phone so I can run a custom ROM, setting this phone up for my fiancees mom. All I wanna do is root and unlock the bootloader to put custom ROMs on it - Is this possible?
There is a thing called xtheme engine. ...and others too....u really don't need a coustom rom.....
