What can I do, with a rooted but bootlocked device?

HELLO XDA :good:
I have a rooted, but bootlocked Xperia T.
I was just wondering, what fun things can I do with it?
I can't install CMW or anything, so isn't flashing things impossible?
Anything would be nice!

you can install cmw on a rooted phone running 7.0.A.1.303 firmware, and you can flash that firmware with flashtool. Read the all in one thread from my signature.
Also, I must ask, why did you root if you didnt know what to do with it? You have just killed your warrenty for no reason..oh well.
What you can do with rooted and locked bootloader
Remove bloatware/debrand phone
Gain access to system partition
install cmw (In 303 Firmware)
Flash stock based roms like mine (Find in my signature) Its 195 based so you will be rooted and still have cmw and be on 7.0.A.3.195

Rooted it for Titanium Backup.
Just checked, and I'm running 7.0.A.1.303 Could I flash CWM using flashtool?
Thanks!

[Q] OTA Lollipop then root?

Hi
Got Z3C, D5803, Android version 5.0.2
Build 23.1.A.0.726
Bootloader Unlockable: No
Can it be rooted?
If so at what cost?
If this has been asked and answered, I'm sorry. Please forgive my search skills.

Hey,
The only way to get root on lollipop is to downgrade to 23.0.A.2.93 (or whatever it is) root that and install recovery.
After that you can flash a pre-rooted zip to get back to lollipop - all this can be done with a locked bootloader
Steps: (All specific instructions to root / install recovery / flash firmware are in the provided links)
Download and install Flashtool
Download a KitKat ftf download the ftf for your phone model (D5803) and download from the version 23.0.A.2.93 list, any brand will do as they are all the same on the inside
Flash the KitKat ftf using FlashTool
Root using giefroot then install recovery with XZDR
After you have rooted and got a working recovery you can go into recovery (when booting, on the sony xperia screen, when you see the green light hold the volume down button) and flash THIS PRE-ROOTED zip (Instructions to flash are within the link)

Thanks for the info.
Seems like a lot to go through to delete bloatware.
I may just stay stock, for the first time ever! Or wait until some genius figures out how to root Lollipop
One question, if I did root with the BL locked would I still get OTA?
Appreciate all the help.

Yep, you would still get OTA but if you did update you would loose your root

Wouldn't SuperSU's OTA survival option work? It worked with the 23.0.1.A.5.77 OTA
I mean root in KK and doing this instead of flashing a pre-rooted fw

Sadly the lollipop (OTA or computer update) seems to completely remove root no matter what survival modes / root keepers you have
In the latest version of SuperSU (SuperSU 2.46) the survival option has been removed. Hopefully soon there will be a way for survival to work - but root and recovery is always better

I had this question too.
Thanks everyone for answering it.
I still have a doubt: In HTC devices you did the same but sometimes you needed to update firmwares, radios and stuff via adb.
How do you do it in sony?or you don't?

{Short version; you don't}
After updating or flashing a pre-rooted zip everything is included in that zip / update file
And with the xperia series there is a model for Asia area (Australia, new Zealand etc) and a model for us and UK areas so if you flash a zip / update for the model that you have everything is included (usually you shouldn't have to flash radio or firmware manually unless you really wanted)

Thanks for the answer.
In HTC devices usually all worked well without flashing radios and firmwares but it was always better to keep them updated.Since I never found any tutorial on how to do that for xperias I found it strange.

sorry to bumb an old thread, but
Hi folks, i just rooted the Z3C of a friend and i am curious wether she could install future OTAs and just reflash superSU.zip from recovery or am i missing something? i find this easier than downloading a prerooted FW everytime.

[Q] Flash new ftf while keeping root?

Hey,
I have a rooted Z3 Compact (D5803) with locked bootloader (via the gfrieroot hack).
However now I still have this old fw and I want to update to the latest KitKat FW, 23.0.1.A.5.77, according to this list:
http://forum.xda-developers.com/z3-compact/general/list-stock-firmwares-d5803-d5833-t2906706
So now I'm wondering how can I do this, with keeping root?
TY
PS:
Before you ask, I want to stay with KitKat until Lollipop is more mainstream -> less problems.

According to the topic that you linked, it is written in the FAQ :
My current firmware is already rooted, will I need to root again after flashing?
Yes you will, as every time you flash you erase the system partition entirely (root included).

Maybe, but I don't know how. Especially since I used a hack/exploit to obtain root w locked bootloader, which only works in that old FW (so I can't just update and do it again).
However from what I read there are ppl who have root, locked bootloader and a recent FW... So I guess there must be a way...

You have to find the original FTF for the version you want (23.0.1.A.5.77), and either make or download a pre-rooted flashable.zip for that version. Then just follow the last part "Install latest firwmare with root, DRM keys, recovery" from the rooting guide again: http://forum.xda-developers.com/z3-compact/general/how-to-root-backup-drm-keys-t3013343
If you want to keep your data partition and internal storage, remember to check "DATA" and "CACHE" in addition to "SYSTEM" in Step 43.

Also, looking at that tutorial it doesn't seem to be necessary to have a rooted phone for that...
Why did I went then through the hassle of downgrading fw, gfrieroot hack and so on? *aaargh*

Well, because you need a recovery to flash the pre-rooted zip, and to have a recovery you have to root first. The pre-rooted SYSTEM partition cannot be flashed using Flashtool because it would not pass signature check. The only way to flash it is to use root access and a working recovery.
Edit: and that reminds me, if you have root but no recovery yet, install NUT's dual recovery first.

Root Xperia Z1 5.1.1 Firmware ?

Hello People Can Any One Tell Me If Theres A Way To Root The Xperia Z1 With The Last Firmware 5.11 Without Downgrade To 5.0.2

kingroot ?

As of the moment, there are no know root procedures for 5.1.1 that have been posted in the Xperia Z1 General section other than pre-rooted FTFs downloaded using XperiFirm through Flashtool. Although - if my memory serves me right - I think I read somewhere here that if you have an unlocked bootloader, you shouldn't really have to worry about rooting as apparently it is easy to get root access. I really haven't explored the part of unlocked bootloaders even though I have a phone that I can unlock my bootloader though to be honest.

Its just around the corners of Xperia Z1 General section I believe. But to be honest, I don't want to mess about with my bootloader - but that's just me, my own preference. The good thing is locked or not, we can still root our nasty Z1 phones!

Personally though, If I have a new phone and it's on 5.1.1, I'll just downgrade to 5.0.2 because I can root it without a PC. Just use Kingroot, (optional) replace KR with SuperSU using Terminal emulator, and Baaaammm!!! phones rooted. Then I'll install DualXZ1Recovery, grab one of the pre-rooted 5.1.1, then flash away baby!!!

Make yourself a ftf.
Use flashtool to download your firmware. Use flashtool again to convert your firmware files to an ftf.

I am new to xda and this is my first post.
I found this thread very helpful but am stock right now...I want to root my xz1 already on 5.1.1, right now I have both ftf files of 5.0.2 and 5.1.1.
My problem now is...how do I create a pre rooted 5.1.1 from the ftf file? And does installing a pre rooted firmware gives all the privileges such as installing fonts?..I'd greatly appreciate your assistance.

You have to use a Windows prog called PRF Creator. With it you can created your pre rooted zip file.
The pre rooted zip file will give you root privileges to your phone. With root you can basically do whatever you want.
To flash the zip you need a working custom recovery on your phone.

[Q] Question Before i do

My phone still unroot and locked Bootloader and Im made mistake upgrade to latest official stock ROM lollipop 5.1.1 bec im having overheat issues, battery draining and weird popup. then im about want to downgrade to kitkat and flash ftf firmware with root.
1) Do i have to Backup TA before i use flashtool? i think if i do flashtool, i will lose DRM keys like sony features? (for locked bootloader)
2) What meaning by 'pre-root' firmware? (*sorry about this. it look new word to me*)
3) without root phone and unlocked BL, is it possible to use PRFCreator? (link: http://forum.xda-developers.com/xperia-z1/development/c6943-368-official-lollipop-5-1-1-t3218004)
I made decide not to unlocked bootloader bec i know its risk to lose but i want to keep it simple only.

you only need to backup your ta partition if you plan to unlock your bootloader. By Unlocking your bootloader you will lose your DRM keys. Anyways having a backup of your ta portion isn't nothing bad.
Using flashtool and flashing a stock firmware will not unlock your bootloader.
2]
A stock firmware comes unrooted. Pre rooted means that the firmware comes with root integrated.
3]
PRF Creator is a Programm you use under windows
4]
You have to understand what a ftf file and a flushable zip means.
Ftf files are flashed with flashtool.
Flushable zip files need a custom recovery to flash. For example twrp or cwm or philz recovery. To get a custom recovery on your phone your phone has to be rooted.

PRF Creator is a stand alone Programm that doesn't require a phone.
It only needs files as input and the result is a flashable zip you must flash with a custom recovery

No.
This zip will launch a program called aroma installer. With this program you will be asked what you want to install.
For example the description of iHackers rom says that you have to choose between stock or custom kernel.
3]
To flash a custom rom or custom bootloader you must unlock your bootloader first. If not you can't flash anything custom.
You can unlock your bootloader with flashtool. For that you need the unlock key for your bootloader. You do this in fastboot mode with the help a flashtool.
Flashing a ftf the phone is in flashmode.
Fastboot mode and flash mode are two different states you can put your phone at.

I am not sure. As far as I understand yes if you choose locked bootloader.
Maybe some other member can help here too.
But to flash the zip you need a custom recovery. For a custom recovery you need root to install it.
Post #4 at ihackers rom Threads mentions the step to flash the rom on a phone with locked bootloader. Not that easy!

Answer is Yes. I've already tried iHackers ROM on my Z1 w/ locked bootloader. I don't want to be rude or anything but all your questions are answerable by going through some basic reading materials that are all available in XDA. I strongly recommend you do your reading first. We don't want you coming back at us saying you now have an expensive paper weight, or that you have lost some important audio, video, image, SMS, MMS, Contact, etc. on your phone. It would really help alot if you read the iHackers ROM thread as well.
You did state on your initial post that you want to keep things simple. Then I suggest rooting your phone, get rid of the apps you won't ever use and just keep it stock.

I don't want to be rude or anything but all your questions are answerable by going through some basic reading materials that are all available in XDA. I strongly recommend you do your reading first. We don't want you coming back at us saying you now have an expensive paper weight, or that you have lost some important audio, video, image, SMS, MMS, Contact, etc. on your phone. It would really help alot if you read the iHackers ROM thread as well.
You did state on your initial post that you want to keep things simple. Then I suggest rooting your phone, get rid of the apps you won't ever use and just keep it stock.

My phone still unroot and locked Bootloader and Im made mistake upgrade to latest official stock ROM lollipop 5.1.1 bec im having overheat issues, battery draining and weird popup. then im about want to downgrade to kitkat and flash ftf firmware with root.
1) Do i have to Backup TA before i use flashtool? i think if i do flashtool, i will lose DRM keys like sony features? (for locked bootloader)
2) What meaning by 'pre-root' firmware? (*sorry about this. it look new word to me*)
3) without root phone and unlocked BL, is it possible to use PRFCreator? (link: http://forum.xda-developers.com/xperia-z1/development/c6943-368-official-lollipop-5-1-1-t3218004)
I made decide not to unlocked bootloader bec i know its risk to lose but i want to keep it simple only.

I just want to answer this and sum it all up.
Do i have to Backup TA before i use flashtool? i think if i do flashtool No, you don't need to Backup your TA partition to use Flashtool. Flashtool works for both locked & unlocked bootloaders.
i will lose DRM keys like sony features? (for locked bootloader) I'll treat this as a separate question. Yes when you unlock your bootloader you will loose your DRM keys, which is why you need to backup your TA partition first before you unlock your bootloader. But as I mentioned earlier - No, you don't need to backup your TA partition if you will not unlock your bootlader. And -No, it is not needed to be able to use flashtool.
What meaning by 'pre-root' firmware? It means it is a stock Firmware that has root access. It is basically your stock firmware that was ran through PFRCreator.
without root phone and unlocked BL, is it possible to use PRFCreator? It's basically like this... NOTE: This is a not-so-details procedure but it will give you an idea on what the PRFCreator is. So the answer is Yes, it is possible to use PRFCreator with a locked bootloader but you need to have a rooted phone with a custom recovery so you can flash the pre-rooted 5.1.1 *.zip file you made, then flash the 5.1.1 FTF using Flashtool
1. Install flashtool
2. Download a 5.1.1 FTF using XperiFirm (it's an icon in Flashtool that opens a FTF downloader that automatically unpacks and makes you a FTF that you can flash on your phone)
3. Download PFRCreator
4. Using PRFCreator you basically create your very own pre-rooted 5.1.1
5. Now you have Two(2) files - the flashable *.ZIP file (the file generated by PRFCreator) and the 5.1.1 FTF you have downloaded earlier
6. You will need to root your phone and install a custom recovery partition on your phone so you can flash the *.zip file you have created using PRFCreator, then flash the 5.1.1 FTF using flashtool
7.
