[Q] How to root my phone - Xperia SP Q&A, Help & Troubleshooting

Ok, it's not like I didn't had search how to do it, it's just that so far my search has been very frustrating.
First, my phone has stock rom, v. 12.1.A.1.201 with JB 4.3. And I just want to flash a stock rom (maybe a little tweak to make it smooth and faster) + root.
So I searched (maybe not too good) how to do it, and I found this: to install any rom, you need to have an unlocked bootloader, so far so good, but then when you search on how to unlock it, surprise! you need to be root to backup drm keys ... Ok then, I tried another aproach, maybe flashing from custom recovery, but then again to install a custom recovery you need to be rooted ... back to the begining.
So if anyone can enlighten on how to fulfill my very reasonable request, I would be sooo happy.

No need to unlock bootloader in order to flash stock based ROMs or for rooting. But for flashing custom kernels/ROMs that need a custom kernel, unlocked BL is a must.
There are many guides. Check through this index.
http://forum.xda-developers.com/showthread.php?t=2618222
It's sticky btw
Basically you have to (because you're locked BL),
1. Downgrade to 4.1.2
2. Root with DoomLord method.
3. Install recovery.
4. Flash a pre-rooted 4.3 ROM (.201) through recovery. Flash SuperSU update at the same time. Shutdown phone (NOT reboot).
5. Flash stock 4.3 kernel (.201) via flashtool.
6. Done. On rooted .201. Then install a recovery (because previous recovery got erased with ROM flashing).
#Details in guides. Good one here: http://forum.xda-developers.com/showthread.php?t=2727143
**Optional: Do a TA partition backup and keep it safe. Someday you can unlock the BL

You can follow mrhnet's post that helped me solve my dilemma! You can downgrade your phone, exploit root, flash recovery, flash SuperSU and then backup TA. Once TA backed up, the freedom is finally yours!

Can someone please help me..
I have an Xperia SP currently running 4.1.2 rooted, bootloader locked.
My aim is to upgrade to 4.3.3 and root, for which i will have to unlock the bootloader. To do so I need a TA partition backup , for which again, root is required.
So, my question is that is it okay if I take a TA Backup now [in 4.1.2] and then upgrade OTA and unlock bootloader, root and then restore the 4.1.2 TA backup onto 4.3.3 in order to restore DRM keys and Relock the bootloader?
Has anyone done this?
is it safe?

Why don't you install a recovery and after that flash a pre-rooted 201???

You don't have to unlock bootloader. You can flash a prerooted rom with built in 201 stock kernel

Just go to the Android development section, and you'll find plenty. You can also choose to flash a stock based rom. I went from 254 to existenz 3.3.0 (which is 201)

[Q] Help with Reverting/Relocking

So I installed CM10.2 on my phone. For that I had to root and unlock my bootloader. I didn't really like it to be honest so I decided that I wanted to go back to stock rom, the problem however, is that i'm not sure how I should do this. I made a backup of my TA Partition so I also could get my DRM keys (Bravia Engine, etc) back. I don't know what I should do first and I was wondering if there is someone who could help me through this process. Do I first need to flash stock kernel, then flash stock ftf, and then install that TA backup in order to relock my bootloader? But I thought I needed root for this, if I flash a stock ftf then root will be gone right? So many questions
Thank you in advance

Thank you for your response but this is only relocking etc. My problem is that I don't know in what order I should do things. So far I think I should do it like this (but i'm not sure, so i'm asking for someone to tell me if it's wrong) : 1. Simply flash a stock ftf (with the ftf the stock kernel will be installed too, right?) 2. Relock bootloader 3. Then apply the TA Backup to get the DRM Keys back.
Is this the right order to do things? Will I make an expensive brick out of it if I do it like that?
Flash a stock FTF and root it (or flash a pre-rooted stock based ROM through recovery ). Then restore TA, which will automatcally lock bootloader and restore DRM keys

1. Unlock your bootloader.
2. Flash DooMLoRD's advanced stock kernel.
3. Flash a superuser zip.
There is currently no way to root with a locked bootloader.

well, in superSU menu, its name is survival mode...which says it will try to keep root permission EVEN in ota. so I guess it's not ONLY for ota.
It won't help when flashing with Flashtool as /system is wiped, so the backup the survival mode makes is wiped also. I've tried before.

I'm using 4.3 with locked bootloader. Do not miss lead people.
You just need a rooted device with recovery option.

Nobody is misleading anybody. There is no way to root with a locked bootloader after you have already flashed 4.3.
Flashing a prerooted rom from a previous, already rooted rom with recovery is a different matter and is not what the original question in the OP is asking.
Sent from my C6603 using Tapatalk
Unlocking bootloader means, wipe all user data, that means more and more trouble to configure al settings and applications.
Just root your older firmware, install dual recovery, and install stock cwm firmware as mentioned in other topics.
Thats all, you have proper rooted and updated versions.

The OP is obviously on 4.3 already.
Downgrading to an older firmware usually requires that you wipe /data anyway.
The OP didn't ask how to upgrade and keep root. They asked how to root 4.3, therefore my original post is currently the only correct answer to the question in the first post.
Sent from my C6603 using Tapatalk
So, lets make a conclusion here.
1- if you have already upgraded to 4.3 you have 2 choices; unlock bootloader and use doomlord kernel, OR downgrade to 4.2.2 and go to part 2.
2- if you have not upgraded to 4.3 yet, you can use a pre-rooted stock 4.3 rom (link of them can be found in this thread) and flash it using recovery and flashtool.
Sent from my C6602 using Tapatalk
If you haven't upgraded, there's a third option. Backing up of the TA partition, flashing new firmware either from ftf, Seus or PCC and then unlocking bootloader, temporarily flashing custom kernel, rooting, flashing stock kernel again and relocking bootloader via TA partition restore.
Takes more time, but its the cleanest way to have 4.3 with root I think.

Or you can wait for OTA release and turn on survival mode of superSU. As SuperSU says, it's NOT guaranteed that root permission will be kept. But if you have patience to wait for OTA release, it worth trying.

He was after a pre-rooted rom but you sent him links to roms that need root to install.
Sent from my C6603 using xda app-developers app
Installing any pre rooted rom requires a recovery which means the user has to have had a rooted device in the first place with a recovery installed. Even if root is lost and a recovery exists a pre rooted rom can be flashed. The links provided above are perfectly fine.

You have 2 options
A . stay away from boot loader (0 Risk):
1- backup your SD data & All SD contents to your computer ( I Think it is not that hard)
2-Flash 4.2.2 with flash tool
3-Root on locked boot loader follow instructions here
4- Install Dual Recovery follow HERE
5- Install 4.3 Pre-rooted from here
****************
Option B.(not recommended if you have not enough experience )
1-Back TA (boot loader ) Here
2-Unlock boot loader Here
3- Root using this method HERE
4-Flash 4.3 pure stock Kernel (Kernel only )
5- Restore your TA (lock boot loader again with all benefits )

[Q] How to root Xperia Z with 569 firmware and locked bootloader?

Hello,
I've got new Xperia Z with 10.4.B.0.569 firmware on it. I can't find solution to root device with locked bootloader. I can unlock bootloader then root phone, but first I would like to backup TA partition, but I can't backup this partition because phone must be rooted first! I can't flash custom recovery too because of locked bootloader.
Is any solution for this problem? Thanks for any advice!
If you want to backup your TA partition, you will have to downgrade to 4.2.2 and root.
There is currently no way to root 569 after you have flashed it without unlocking your bootloader.
Sent from my C6603 using Tapatalk
Thank You for advice. Is there any difference between downgrade firmware and flashing other firmware using flashtool? I mean can I download stock, previous firmware, flash it using flashtool on device with locked bootloader?
Yes, use Flashtool to flash an earlier firmware.

i don't recommend you to unlock bootloader as there's many steps to do which takes time.
so you will just need to downgrade to 4.2.2 firmware by flashing the ftf,then root it & install custom recovery,after that flash a pre-rooted 4.3 rom.

too late. i already unlocked my bootloader. but after i unlocked it, my phone on bootloop but i managed to enter cwm. the 'free xperia' and 'xperia' logo keeps coming out if i try to boot my phone. looks like im on a wrong firmware to unlock my bootloader.
now im downloading (C5502) 10.4.B.0.569 tft files and flash it via flashtool, then im gonna try to again if my phone will boot or not.
@Ben Ling
I am new this rooting to. And I want to install a custom rom on my Xperia ZR. How do I downgrade to the previous ROM? Do I just use the flash tool? Is it necessary to backup my TA partition during this process or can I do it when I am about to root the device?Thanks!

download the 4.2.2 ftf,flash it then root it & install recovery
then flash custom rom (only based on 4.3 & stock firmware)
Thank you
So basically these are the steps which I need to perform
1)Download and run flash tool
2)Download the correct ftf and flash it via flash tool
3)Root the phone using doomlord's vroot kit
4)Backup the TA partition
5)Unlock the bootloader
6)Install custom rom
Please confirm if these are the steps to be followed
Thanks!
If you only want root you dont need to unlock bootloader and backup TA.

I live in India so would there be an India specific rom(Stock) for my phone?
@Ben Ling I rooted my zr by flashing 4.1.2 . I have also backed up the TA partition. Can you please suggest any good ROMS now? What should I choose stock based ROMS or AOSP roms like Carbon?
Also, If I want to come back to stock ROM(4.3) again what should I do?
Thanks!

if you want 4.4,then just try the carbon rom
for 4.3,try this.. http://forum.xda-developers.com/showthread.php?t=2726463
for back to stock,you will just need to backup your current 4.3 rom,then if you want to restore,just restore
but the backup will only restore by using the same recovery that you backup.
@Ben Ling Thankyou! One more question before I installed the 4.3 ROM which you mentioned, do I need to unclock the bootloader to install the ROM?

Hi,
Guys, I just need root access on my Xperia SP (C5302). I'm not interested in installing custom ROMs. If there's a method to achieve it, please post it or a link that would help me. The bootloader is locked and the build is .201.
I tried few vRoot and Kingo, but none helped.
Again, I just need root access.
