Ok, first of all: I used the search button and Google a lot before coming here to post this.
My question is totally noob: can I make a NAND backup of my mobile, *before* rooting it, *before* installing custom recovery?
I'd like to do it because I'd really like to install a custom firmware (I'm oriented towards Prime or Megatron) on my O1, but I really want to have an opportunity to come back to the original firmware in case I need to repair my phone.
I've seen a large number of ways for doing backup of a phone *after* the custom recovery, but no one before.
Another question is: is it necessary to install the Android SDK for installing custom recovery, or can I run the adb commands from my mobile?
Thanks everyone in advance for the help!
The answer to your question "can I make a NAND backup of my mobile, *before* rooting it, *before* installing custom recovery?" is no. The custom recovery is the software that provides the nandroid backup facility. Without that custom recovery, you can't make a NAND backup (yet another good reason to do it).
What you can do is to backup the existing recovery image. From http://forum.xda-developers.com/showpost.php?p=9377725&postcount=9, you can do
Code:
dd if=/dev/mtd/mtd2 of=/sdcard/recovery-dump-T.img bs=4096
which will save off the stock recovery image to your sdcard. If you want to restore to the stock recovery, you can do
Code:
flash_image recovery /sdcard/recovery-dump-T.img
after you have installed the flash_image program. (Installing the flash_image program is a completely reversible step that needs root permissions, but can be completely undone.)
For your second question, all of the commands can be run from the Terminal on your phone. Note that your phone will need to be rooted and you will have to do "su" before you start typing commands. Having done "su", your prompt should turn to # instead of $.
Thank you very much for your detailed answer.
Now the question is: do I really need to do all of this stuff, or there's a way to bring back to the phone to original recovery/original OS without doing a backup myself, i.e. there is some image available from LG that restores the phone as out-of-the box?
There is only one tool from LG - LG update which updates whole your phone. It rewrite everything, also custom recovery.
Same "work" can be done with tool called KDZ_FW_UPD but, I didn't recommend it if it is not necessary.
For more information about KDZ_FW_UP take look on http://forum.xda-developers.com/showthread.php?t=875881

GPe Owners: Do not try and flash any FTFs to your device. You will BRICK it with no way to recover it.
Go to this thread and follow the steps.
Back up TA Partition:The TA partition is the "Trim Area". There are lots of things stored in here like root certs, revoked certs, DRM keys, current firmware version,... the list goes on. What we are concerned about here is with the DRM keys. Some service centres will not service a Sony device if these are missing. Unlocking the BL will erase these.
Once you lose these keys, you can't get them back, so backup the TA and upload it to your Dropbox etc
You will need Backup TA for Sony Xperia by @DevShaft Please read the thread.
Instructions:
Download the latest version of Backup TA.
Extract the ZIP file to a folder location of your choosing.
Navigate to the folder location of Backup TA.
Make sure no other script or application which is using ADB is running.
Make sure the device is booted in normal mode (the way you normally use it).
Run Backup-TA.bat
Read the last paragraph of the license before continuing.
Read the information and follow the instructions given by the tool.

Unlock the Bootloader:This will wipe your phone, so backup your stuff
You only need to unlock the bootloader if you want to run either a custom kernel or a custom ROM. Most ROMs based on the Sony releases will run on a locked bootloader.
Instructions:
Go to Sony's Developer site
Request the unlock key and check your mail straight away. Email is quick these days.
Open the latest Flashtool on your computer
Click the "BLU" icon
Follow the steps and enter your unlock key
Install Custom ROM:To install a custom ROM you will have to complete the steps above (ROOT, Back up the TA Partition, and Unlock the Bootloader) you dont need to have installed recovery but it will help you make a backup of the current state of your device.
After the above are done:
Backup current software with custom recovery (TWRP or cwm - use the same recovery the the new ROM uses*)
Downlod ROM
Extract boot.img from within the .zip
Flash the boot.img (not absolutely necessary but will mean you are on a recovery that is tested to work with the ROM)
In fastboot mode use either flashtool or the fastboot commands
- If you want to use the boot.img's recovery to make a back up of the current software/state of the device use:
Code:
fastboot boot boot.img
- or if you just want to flash the kernel and recovery to flash the ROM use:
Code:
fastboot flash boot boot.img
fastboot reboot
Wipe Data
Wipe Cache
Wipe Delvik Cache
Flash ROM
Reboot
*CM based ROMs normally use CWM. Slim and Omni based normally use TWRP
Using flashtool:Please use this very good guide: Flashtool XZU
Back to Stock:
To get back to pure stock Sony there are several things that need to be done:
Make sure you have root
Backup any data/photos/etc on the phone
Restore your TA backup with the TA backup tool above
If you are on a custom kernel or ROM you ZU will not boot at this stage
Start flashtool and load a FTF
Start the flash and wait for the onscreen instructions to connect the ZU
Connect your ZU in flashmode
With the ZU powered off
Connect to PC while holding the volume down key
Flash will start
Wait for flash to complete

As always, very informative blueether.
Questions:
(1) Does this mean we no longer need to downgrade/upgrade/restore imei etc?
(2) Unlocking the bootloader is a requirement for installing any rom? No way around this?
(3) I understand the need for the disclaimers but rooting/unlocking BL doesn't automatically void your warranty does it?

1/ was only needed on 4.2
2/ added a line
3/ ring Sony and say this: "I rooted my ZU, and now it won't boot. Can you fix it for me?" what do you think their response will be?
With the warranty question: I asked because I'm more concerned about the cracked glass issues than bricking the device because I couldn't follow instructions. Thanks again for the instructions.
I may sound dumb but if I am only interested in root just for link2sd feature & foldermount to overcome internal storage limitation by transfering to SD card then do I have to follow all steps ? or only first 2 step will do i.e. Root & install SU.
I will just root it & don't want to touch TA or Bootloader as not planning to update with custom rom. please suggest that even for rooting do I need to backup TA / unlock bootloader.
also will new update of Android Lollipop will wipe my root or will I be able to upgrade to lollipop in later on stage with Root.
please reply on this.
Nice with an updated version. Do speak up if you need some help with anything.

My XZU hasn't arrived but my experience with other phones is that root alone should allow you to use link2sd and fouldermount.

Yes if you just need root the only go that far
OTA will probably fail with root, and flashing a FTF will wipe root when L arrives
rooting is not working. stops as there is no tr.apk included. In the guide there is nothing about tr.apk needed to be downloaded as well as that you need to donate before you can download. I dont mind to donate but I need to know it will work.

I am pretty certain that you have to go back to stock to receive the OTA, but I think that would apply also if you only rooted. Flashing an ftf file with flashtool without checking the boxes to wipe data is what I have seen recommended to get back to stock. I hate giving an answer I am not one hundred percent sure is correct so I will call on some experts, @blueether or @HEPennypacker can you confirm this is correct please.

Greetings,
I have for the last few days been reading though a lot of posts on this forum containing guides for howto root, backup TA, unbrick and installing custom ROM etc.
I must say, I am getting a little confused, because they there seems to be a lot of different guides and methods, some seems old and (perhaps) outdated, some are very easy and other very complex in comparason.
So, please forgive me, but I would just like some advice on the current best and easiest way of performing what I plan.
I am getting both a Z3 Compact Tablet Wifi (Hence why I am posting on this forum) and a Z3 Compact Phone. So both Stock ROM and locked bootloader.
For the Tablet I would like to Backup TA, Unlock Bookloader and install CM12 w/ Google Apps Nano (Or what the smallest GA Package is)
For the Phone I would like to Backup TA, Unlock Bootloeader and Install CM12 (No Google Apps).
But First a General Question:
I get the impression that on some versions of the Tablet, the bootleader cannot be unlocked? (ref: http://forum.xda-developers.com/z3-tablet-compact/general/root-flashing-construction-t3091763 -- "Please note! It will only be possible to unlock the boot loader for certain releases of this model. You can check if it is possible to unlock the boot loader of your device by checking the service menu.")
If this is true, is there any way of telling when I am buying if I am getting an "unlockable" tablet?
The posts and guides I have been looking at are:
http://forum.xda-developers.com/z3-tablet-compact/general/root-flashing-construction-t3091763
http://forum.xda-developers.com/z3-...t-rooting-sgp611-giefroot-bootloader-t3017314

http://forum.xda-developers.com/z3-...t/root-root-locked-bootloader-sgp621-t3013534
From what I've gathered, the steps are roughly as follows:
1) Put device in USB debugging mode and Install USB drivers (Fastboot for instance)
2) Place SuperSU on a SD Card
3) Install Dual Receovery "TabZ3C-lockeddualrecovery[VERSION]-RELEASE.installer.zip" as pr: http://forum.xda-developers.com/z3-tablet-compact/development/tabz3c-xzdualrecovery-qa-t3014211
4) TA Backup as pr: http://forum.xda-developers.com/z3-tablet-compact/general/root-flashing-construction-t3091763
5) Unlock Bootloader, also as pr: http://forum.xda-developers.com/z3-tablet-compact/general/root-flashing-construction-t3091763
6) Flash " TabZ3C-lockeddualrecovery[VERSION]-RELEASE.flashable.zip" as pr: http://forum.xda-developers.com/z3-tablet-compact/development/tabz3c-xzdualrecovery-qa-t3014211. I am a very unsure about this step, it says "Be sure to flash TabZ3C-lockeddualrecovery[VERSION]-RELEASE.flashable.zip from http://nut.xperia-files.com after installing the ROM and before you reboot, this way you will not lose recovery!". What does this mean?
7) Boot into recovery and install CM and GA (and SuperSU again?)
I apologize for being thick, but there is a lot of cross linking in these treads and some are 100+ pages long, so if there is important details hidden, spotting this is difficult.
Thanks for any help!
Sorry, i do not speak english (i use Google translate). Briefly:
For backup TA + installation CM 12.1
1) Install Drivers (adb, flashmode , fastbootmode)
2) Root with kingroot (it is only compatible with kitkat and lollipop 5.0.2, downgrade if necessary with flashtool)
3) Backup TA (Important)
4) Unlock bootloader . Reboot
5) Copy CM Rom, gapps and supersu zip´s to internal memory (or skip and use sideload)
6) Tablet in fastboot mode (vol+ and connect USB)
Type (PC): fastboot flash boot boot.img
(extract boot.img from the zip of CM)
7) Type (PC): fasboot reboot
When the LED is purple press v- to enter recovery Cyanogenmod
Flash cm.zip. gapps.zip and supersu.zip
8) Reboot, Finished

Current Situation:
-Phone is on KK (version .167)
-Phone is working fine, no problems at all
-Has Locked Bootloader
-Is Missing Recovery
So my questions are:
1) Can I install recovery WITHOUT having to unlock my bootloader or flashing another rom?
If yes, then could you perhaps provide me with the necessary information to do it? (if I need a PC, and where to find the required programms, I will do everything else on my own)
2) Can I take a Nandroid Backup of just the system? (not the apps installed by me)
3) If I have a Nandroid Backup, flash another android version, and then restore the backup, everything should be as if I never flashed anything right?
4) If I take a Nandroid Backup while on locked bootloader, flash a rom, unlock my bootloader, flash a kernel, and then restore my backup, what happens?

Yes. This has been asked and answered. There is a search button to assist in asking siple thing. There is also google.
1. Root with community root kit, towelroot or king root. Install recovery image. Google twrp and it'll tell you how to install with dd.

Not really. You can take a complete backup and restore the system partition only though. Look in advanced restore of recovery. This will only recover the system partition and not the apps you install (assuming you don't install things on the system partition).

Yes depending on what you restore and what you wipe. E.g. If you don't wipe data you may get some interesting things like force closes or boatloads.

1- You don't need to unlock the bootloader, there is no reason to do that. You must downgrade to 4.4.2 to install a recovery - A downgrade means you'll loose your apps and settings.Unlocking the bootloader will trigger factory reset too. And yes, you will need a PC or Mac with all the drivers installed (ADB and Flashmode are a must) See NUT's XZDR: http://forum.xda-developers.com/showthread.php?t=2261606 Download the older installer from his official download page and search for Z2-lockeddualrecovery2.8.21-RELEASE.installer.zip . It can temporarily root to install the recovery. After you have a fully functional recovery you can install the SuperSU .zip
2- Use TWRP to make a backup, also you can make a flashable update package by yourself by using PRF Creator: http://forum.xda-developers.com/crossdevice-dev/sony/tool-prfcreator-easily-create-pre-t2859904 (You will need this to keep root/recovery on Marshmallow)
3- I usually do clean installs, so I can't answer this one
4-If you unlock the bootloader it will stay unlocked until you manually relock it.
BEWARE! Unlocking the bootloader on a Xperia is more of a downgrade. You will loose proprietary functions like noise cancelling, a bit of camera quality, some GPS functios, official updates, DRM keys...etc. First try to root on 4.4.2 and do a TA Backup (Trim Area) BEFORE tinkering with the bootloader. The DRM keys are unique to every phone, they are not interchangeable and cannot be recovered after you unlock the bootloader. Bootloader unlocking will not unlock the SIM card.

Also not true. Root with towelroot ask (https://towelroot.com/) and install twrp. Can be done from phone 100%.
Dd Install Method (Requires Root):
Download the latest image file (.img) from the download link above. Place it in the root of your /sdcard folder and rename it to twrp.img. Run the following commands via adb shell or a terminal emulator app:
su
dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel

Thank you guys for your responses, I know I should have searched before actually asking these questions. Anyways, thanks for saving me from actually having to search!
I have found many sites with conflicting answers, so please don't tell me "google is your best friend" for my silly/already asked questions...
So first what I have: a 5 month old, non modified M4 aqua (E2306), bought from a Canadian carrier. The firmware version is 26.1.A.3.111 (bootloader locked). My goal is to root my phone when I update to MM (using the method PiSpecialist has posted, I cannot post links), but I haven't done so for the fear of losing TA partition when unlocking BL. There is currently no way to root MM with locked bootloader.
Now, my questions:
1. When I unlock my BL, I will lose the TA partition (DRM keys) of the device. Yet to back these up, I need root access. Should I root my device while it is still on Lollipop? There are ways to root BL Lollipop correct? If so, please link a preferable way to do this.
2. Will I receive OTA updates after rooting my phone? If not, I should download and flash firmware from Xperifirm?
3. Will I lose root when flashing new firmware (e.g. flashing MM to a rooted Lollipop device)?
4. Is it dangerous to flash official firmware to a rooted phone? What is a safe way?
I found that dealing with TA is dangerous and can hard brick a phone. Anybody found a reliable script/tool to do this?
So this is pretty much what I am planning to do so far, if the above is correct:
Root my phone while it is still on Lollipop with a locked bootloader.
Backup my TA partition.
Get MM (from either flashing, or OTA, depending if I still get OTA updates)
Unlock bootloader (as there is no way to root for locked bootloaders in MM)
Root phone while it is on MM (if I don't keep the root after updating from lollipop)
Restore TA partition
DONE!
Not as many questions as I thought.... Any other advice/things to look out for would be appreciated
Theres no way yet to have root in mm /system, it needs to be in kernel and you cant use custom kernel and restore ta. All the questions you did are already answered in forums.
But in case your interested ill tell you what i did step by step to have original TA part with drm and "tunned" but unrooted /system.
Keep in mind that your warranty is void, you will loose all your data and you may brick your device. Messing up with TA partition is serious and dangerous stuff. The following steps are just to tell you what i did.
If you want to do so, do it at your own risk.
1. Clean install LP 3.120 via flashtool wipping user data.
2. Root with rootkit 3.xxx and installed twrp for BL
3. Backup TA
4. Unlock bootloader and install MM fw via flashtool
5. Now with BU installed boot.img and recovery.img
6. Now with root, deleted unwanted apps, installed adblocker, installed xposed, tunned some settings/apps etc.
7. When /system was how i wanted, i made a backup via twrp (data, system, cache).
8. Clean install LP 3.120 again via flashtool, wipping user data.
9. Root via rootkit and installed twrp for BL.
10. Restored TA partition
11. Restored the backup via twrp and SHUTTED DOWN the phone because itll not match with the rest of the fw.
12. Installed MM fw again via flashtool but this time, excluded /system part and DID NOT WIPE user data nor Apps log. (as ive restored MM /data backup before)
13. Started the phone.
Now i have MM with drm, locked bootloader, unrooted, xposed working with few modules, adblocker applied and some other mods. Also i receive updates via sony apps such as whats new. And the low speaker volume seems to be fixed.

Theres no way yet to have root in mm /system, it needs to be in kernel and you cant use custom kernel and restore ta. All the questions you did are already answered in forums.
But in case your interested ill tell you what i did step by step to have original TA part with drm and "tunned" but unrooted /system.
Keep in mind that your warranty is void, you will loose all your data and you may brick your device. Messing up with TA partition is serious and dangerous stuff. The following steps are just to tell you what i did.
If you want to do so, do it at your own risk.
1. Clean install LP 3.120 via flashtool wipping user data.
2. Root with rootkit 3.xxx and installed twrp for BL
3. Backup TA
4. Unlock bootloader and install MM fw via flashtool
5. Now with BU installed boot.img and recovery.img
6. Now with root, deleted unwanted apps, installed adblocker, installed xposed, tunned some settings/apps etc.
7. When /system was how i wanted, i made a backup via twrp (data, system, cache).

Thank you.
What adblocker can be install?
Btw, false alarm regarding speaker volume, it still saturate with bass at higher volume resulting in a lower and kinda cracked volume output, it may need to be tweaked, or even try to port LP audio parametres to MM rom, if thats even a thing and possible, until sony fix it (if they do lol). Ive tested a variety of songs

Theres no method at this moment to put su binaries in /system, but if you dont mind you can keep the root as long as you dont restore your TA / lock bootloader as it needs a stock kernel signed by sony.
I enter twrp recovery in MM by holding power+vol down

I don't understand about "excluded /system part"? Flash only system file or everything

No, you exclude system as you restored it early via twrp, flash the rest of the firmware like modem, kernel etc. Remember to dont wipe data and apps log also
Edit: if you flash system youll loose the changes you did thats why you need to exclude from bundle when choosin in flashtool

Thanks! This was what I was looking for!
Also, will you be able to root after this? (If someone comes up with a method)

Your welcome. Yeah if someones finds a way to do the classic root like in LP this will be rootable for sure.
At least in the meanwhile we can have ads blocked and xposed with some modules and still keep bootloader locked with drm keys to keep functions and receive updates.

This is what im going to do...
Root bootloader locked in LL
Back up TA
Unlock bootloader
MM through flashtool
Root MM (boot.img , recovery.img) (This IS what you did by flashing these, right?)
http***://forum.xda-developers.com/m4-aqua/general/root-t3421932 (going to use this boot and recovery .img)
Chang/add to Marshmallow firmware
At this point, the device should be rooted on MM, with UB TWRP and SuperSU.
Now, is it okay if I just restore TA partition NOW, instead of going back to LL? I'm not really interested in saving OTA updates... speaking of which, how did you manage to still get them? I thought as soon as you modify your device, you are excluded from OTA updates...

Yeah you root mm by flashimg boot.img.
First, some people reported that is recommended to restore TA partition in the same firmware as you backed them up. Second, if you restore your TA and you have custom boot.img (like that one to get the root) your device will not boot

i have locked bootloader and its not unlockable (buyed to a company) and after some test i can tell you that don't need to unlock bootloader to do this
you can do it from rooted LP with twrp, first wipe data , system and cache, install MM fromzip (you can create the zip with PRF creator using the dummy_flashable.zip instead supersu zip) after MM its installed you can now install xposed, and other kind of flashable mods, lastly, power off phone and flash tft skipping system.sin
you will have android modded and untouched bootloader without root

id rather prefer to do the system changes with root in the mm firm, but sounds like a good method for those ones that cant unlock the BL.

Can't everyone unlock from the Sony website?
DarkerJava said:
I have found many sites with conflicting answers, so please don't tell me "google is your best friend" for my silly/already asked questions...
So first what I have: a 5 month old, non modified M4 aqua (E2306), bought from a Canadian carrier. The firmware version is 26.1.A.3.111 (bootloader locked). My goal is to root my phone when I update to MM (using the method PiSpecialist has posted, I cannot post links), but I haven't done so for the fear of losing TA partition when unlocking BL. There is currently no way to root MM with locked bootloader.
Now, my questions:
1. When I unlock my BL, I will lose the TA partition (DRM keys) of the device. Yet to back these up, I need root access. Should I root my device while it is still on Lollipop? There are ways to root BL Lollipop correct? If so, please link a preferable way to do this.
2. Will I receive OTA updates after rooting my phone? If not, I should download and flash firmware from Xperifirm?
3. Will I lose root when flashing new firmware (e.g. flashing MM to a rooted Lollipop device)?
4. Is it dangerous to flash official firmware to a rooted phone? What is a safe way?
I found that dealing with TA is dangerous and can hard brick a phone. Anybody found a reliable script/tool to do this?
So this is pretty much what I am planning to do so far, if the above is correct:
Root my phone while it is still on Lollipop with a locked bootloader.
Backup my TA partition.
Get MM (from either flashing, or OTA, depending if I still get OTA updates)
Unlock bootloader (as there is no way to root for locked bootloaders in MM)
Root phone while it is on MM (if I don't keep the root after updating from lollipop)
Restore TA partition
DONE!
Not as many questions as I thought.... Any other advice/things to look out for would be appreciated

If on rooted 5.0 all you need to do is flash a pre-rooted mm zip via recovery on lollipop, no need to unlock the Bootloader for root unless you have a device that has drm-verity security activated.

Oh yeah I completely forgot about that... someone released a prerooted rom about a week ago on the forums. This will less complicate the process for bl locked rooted MM, thanks!
