Remove root - Xperia Z Q&A, Help & Troubleshooting

Hi,
I am trying to install the barclays bank app however it wont work since my phone is rooted. I have tried using the permanent unroot option in supersu but this doesnt resolve the issue. Does anyone know how I can remove root so it doesnt recognise that the phone was ever rooted.

Just flash a stock ftf with flashtool and root is gone, or make a sw repair thru PC companion, same result.
If I helped you, hit the tanks button...

I know I can flash a stock rom but the thing is I dont want the apps that come with it, like facebook and all that trash.

[Q] Question about Rooting and Returning to Stock

My apologies if this has been asked before... I've spent some time searching both here and google, but I don't think I've found a thread that answers this question specifically.
First:
I've rooted (Using SuperOneClick) for the first time to use the "Battery Calibration" app (which works great by the way), but then started getting a little creative and removed a whole bunch of stock bloatware and other programs I don't use from my Bell I9000M.
Now, after using it for a couple of days, I noticed under WhatsApp settings under "About", when I hit the "Contact Us" button, it stated no Email App was installed (I removed the Gmail app, as I only use the built in Samsung Social Hub email). I didn't really notice if Gmail was the only selection in there to begin with, but it appeared weird to me.
So, while the phone was still rooted, I did a factory reset. After doing so, I noticed the phone was still rooted (I think - SuperUser was still there), and none of the Apps I originally removed were there.
Then, I thought I screwed up the Rom, so I used SpoofFW under root and manipulated the firmware version so Kies would allow me to redownload KC1. It did so, but after the ROM was installed, SuperUser was still there, but all apps were back.
I was under the impression that when you update your phone via Kies, it returns to full stock. Guess I was wrong.
So how do you bring it back to full stock, eliminating any traces of Root?
I've never installed anything beyond root... no kernal changes, new roms or anything else.. just SuperOneClick.
Can anyone help? Sorry about the wordy post.
SuperOneClick should offer the possibility to unroot too.
If not you'll have to flash an unrooted stock-FW (available at samfirmware.com).

Thanks for the quick response..
It does offer the ability to unroot... is that the only thing required?
I'm asking as we all know, when we uninstall stuff in Windows, traces of the program are still hanging around.
Android is familiar with Linux, not Windows.
If you unrot and uninstall all apps which require root nobidy can say if your phone was ever rooted.

Thanks pal... appreciate everything.
So all I have to do is unroot and basically install KC1 from Kies or ODIN to restore the Apps I've deleted and I'm good to go.
Again, thanks for all your help. I'm by no means anywhere close to realizing the true power of what this phone can do, its great to have knowledgeable people such as yourself to help people like me.
Thanks, but we all are here for helping others.
I am wondering the same thing. I'm new to this so I don't know how to check what was my stock version with bell mobility in canada.
I want to go back to the original factory default settings when I purchased the phone with bell.
Can you guys help me? thanks!

Unbricked phone, is it still rooted?

Not sure how to check this but I semi bricked my phone last week, and thanks to you guys here for helping me getting it back up and running.
But how can I check if it is still rooted?
Some of my programs are not working anymore
Thanks
Download root checker from play store. That app will simply tell you whether you are rooted or not.

If you don't know if your phone is rooted it means you don't use apps which requires root which in turn means you have no need to root your phone!

I have not re installed them yet ok, and as you can see from the previous post I have already determined it is not so why you felt the need to make a snide comment is beyond me.
Root very quickly. Upload the official ICS ROM with PC Odin. Then upload the stock recovery using the kernel from this thread. I've done everything. http://forum.xda-developers.com/showthread.php?t=1901191

Hi there, can you flash the SuperSU.zip from Recovery? I've lost root numerous times (after flashing certain kernels) and SuperSU works fine for me.
I hope this helps. Please hit THANKS if it did.

Still have Odin on my phone, will that need to be removed if I am adding ICS with it already attached?
Also my kernal version has changed like 2x today from all of the updates (LRK currently) will have to find a new way to root vs the way I did it when I was on KKA or whatever it was

PureXaudio and ota update

I have purexaudio installed and I know that the dev wont make instructions how to uninstall it. Firmware is .423 and I was wondering if anyone has worked out how to uninstall it like in an easy way so you can get ota update working again?
The thing Im trying to avoid is downloading a, rather "huge" in my case, stock rom where I will also lose all data or progress on my current apps unless I do backups.
So, any work arounds?
When you flash any rom with flashtool you won't lose data.

I don't think there's an instruction to uninstall. Zero even says he won't give instructions to uninstall. There's only a zip which resets the volume to stock values. I'm assuming volume is stock but the mod is still there . But then again op can just use flashtool to flash new firmwares.

A simple back-up would've helped.
You had to make a backup before flashing it. Zero wrote only to revert the VOLUME back to normal.

I know I had to make a simple backup before flashing but I didnt since I didnt have access to my pc and really had no space left on my phone.
Thats why Im asking if there is any other way.

[Q] Confirming the Stuff i need to do

NOTE: MODS, i know i could have used an existing thread for this, but i need the information in a proper way and maybe ask some repeated questions.
Hi guys,
I recently bought my first sony phone. Mighty impressed, i must say. Being an old HTC fan, i didnt expect i will ever make a jump, but this phone hooked me.
I have worked a bit for the development of HTC and some other phones, so i know what to look for and where to. Reading all the guides here, this is what i concluded if i want to safely unlock bootloader and flash some CM goodness. Please read my steps and let me know i am doing the right thing:
1. Root (via Doomlord thread guide. Flash old kernel, use exploit, then flash new kernel back)
2. Backup TA partition (for the precious BE2 and other magical SONY stuff)
3. Unlock BL the official or unofficial way, (as it doesnt matter because i can always relock it using TA backup , am i right???)
4. Flash CWM/TWRP etc and enjoy all the custom roms. (never look back)
Much appreciated guys. I will surely contribute with my own flavor of aokp once i get the basics correct. Not so soon.
Regards
neXusPRIME
Yes and Yes.
The steps you described are the proper ones
Yep that's the right steps to do!Have fun unlocking your device
Real benefits of unlocking bootloader? And can I use custom roms without unlocking?
Found it. I need to unlock before flashing non stock custom roms.

No if your bootloader is untouched it will update you will lose root tho

Rooting will not flash a custom recovery it will just install a SuperSu app and su binary. U can use a stock firmware and flash it using flashtool to get back to stock

One last question before taking the plunge.
What if i flash a generic stock FTF (for my c5303 ofcourse), but not caring about the branding, will that also be okay for OTAs or will i have to repair/update via PCC SEUS?
In other words, how do i know which branding stock ftf do i need? About Phone page doesnt have that info i think.
I am not worried about system partition or anything, but i want to make sure i have stock recovery of my phone which will guaranteed work when i get the 4.3 OTA.
for rest, ill root, flash CWM and nand backup all things.
btw, it was so so easier on HTC

You can restore you phone with SEUS also with Flashtool ofcourse.
It does not matter what kind of firmware you flash as long as it is an C5303 one. I had dutch Vodafone Branded and I flashed a Generic EU one without issue the updates will be provide by Sony and not vodafone (my case).

Used sony update service to repair my phone,
Its back to unrooted stock 254
i think twrp messed something up.
Is it recommended or CWM only works?
on my old phone, twrp was more reliable.
There is something fishy with sony mobiles.
I know the modding stuff is more safe due to flashtool being always available for the rescue, however common stuff such as unlock, TA, recovery and etc are much too complicated for the newcomers.
even being n RC for porting TWRP to two htc phones didnt help me there.
Stuff dont work the first time.
In my case, the problem was,
flashtool worked the second time for flashing 254 kernel
doomlord kit worked the second time for rooting (i really dont know why, but it wasnt related to kit, something up with usb debug n permissions)
installing CWM didnt work the first time as well, (not the fault of installer, rather first time fails coz u give SU permissions just then, so something is missed, 2nd time, the SU permission is already there, so it works)
and ROM flashing almost always needs wipe dalvik/data/cache etc otherwise you might mess something up...
Its a lot safer if i see it one way, because these steps are more foolproof, but on the other hand, a lot more complicated, then say HTC or samsung phones. especially as i havent unlocked my BL so being cautious at every step.
Anyways, all things are fine now, using existenze ultra and enjoying it every bit.
Will step more carefully now on, using above as experience. Thanks all. This thread is closed until i have another problem

Why does it work better rooted ?

Hi peeps.
I was rooted a while back. Had problems with phone freezing mostly when using camera.
Sooo i unrooted, relocked bootloader and then used the Sony update to repair. So ive been on .757 pure stock and i got more problems with that, touchscreen was weird from time to time. It rebooted once a day and it didnt matter wich task i was doing it seems (when rooted it only happened during use of camera and mostly AR effects). So now i became random reboots.
Well i rerooted now and now i can use the AOSP brower again(thank god for that) and most things i wanna have working are working. Havent tested it for that long yet when rerooted but keeping fingers crossed that it will work like it should. Possibly some random reboots wich i dunno whats causing them.
But isnt it strange.
I was wondering about something though. Scrolling seems not so smooth when rooted, but that might be placebo kicking in.

I was wrong It worked just as bad with rootaccess now. So I repaired the phone again with Sony update.
I just wanna get rid if this phone now, it gives me me a headache!!!

if you get reboots on Custom Roms with Custom Kernels, well, it's not strange to me, it happen many time, BUT if you get random reboots on Stock, then I will should be worry about it. For all the other reasons you have to have them less on stock, if you really still have all this issues then I will replace it via warranty. I heard some Xperias was not fixed with any Firmware.
Well that's just it. I have reboots on stock rom with stock kernel. Usually once every day. I can't get rid of it. I've repaired and repaired and it is still the same.
Here is the funny part, the warranty of the phone expired one month before I even bought it when I was in touch with Sony. I have abit of an argue with my retailer atm since he says it's software related. And im saying I wanna return it. And get either money back or a new working phone.

Reflash stock rom via flashtool. It sounds like your just repairing the device. Do factory reset and flash stock rom.do a back up first.

I am on .136 stock (4.3), no root, no unlocked bootloader... all works fine...I have read so many people complaining about newer updates to .681 or .757 .... I do not see any point updating to newer versions, as I am not missing anything major with .136

That isn't anything to do with rooting m8, how you flash your phone and what you flash onto your phone, the apps you use or don't use and your actual habits you have, these are some of the things which cause random reboots and problems for the most part, the other is bad luck and hardware issues.
Particular devices did have some rebooting issues, I myself haven't had one in a long time so i don't get them at all, whether i'm on a custom rom or an AOSP rom, I do get the occasional slow down but there isn't a phone out there or PC for that matter that never slows down at any time.
What I would say to do is to clean up your internal and external memory and download a tried and tested rom, lets say monxified 6.0.3
Go back to 534 and re-root, install a custom recovery and flash that bad boy (don't forget to perform a full wipe, factory, cache and dalvic) use a full FTF to fill in the blanks using flashtool (avoid flashing system and TA , exlude wiping with flashtool) Do not restore using recovery either.
Don't flash a custom kernel either, just let the system boot and see how it runs, install one or two apps (not a massive restoration using titanium) Avoid xposed for now and reboot the phone.
See if you can leave it like that for a while and see if you get any random reboots.
Do it by the numbers methodically and you should be fine
Good luck
How do I wipe everything with flashtool.
Last time I rooted I flashed 681 with flashtool. Had strange reboots then aswell.
Let me say this, I have unlocked the bootloader and I do not have backup on my TA. Wouldn't older roms then 681 mess up my phone? Bootloader is relocked with flashtool and I ain't rooted and I don't have CWM installed anymore.
So easiest way to clear the phone would then be? And I want to use Stable Sony rom.

Yes, this is what I meant, just click on Wipe Data, Appslog and Cache. Still not a full format of your system partition but this is what it do to make a clean installation.
Well I did that a few days after I received my phone. I had the same problems back then. I actually did just that one hour before making this post aswell. Hoping it would work good, which it didn't.
If the phone would have been in my possession a little longer I would run it over with my car. Now it's quite new so I won't do that but I'm really tired of it and it's so boring have to send it to my retailer for repairs and w8 forever. Then when I get it back. I BET that they only will flash new software and test it for five min and ship it back and it will still have the same problem.
Been there done that alot of times with other things

I was thinking rolling back to 4.3 though to see if that would be more stable. Noticed that, if the phone don't reboot in a day wich it normally does then the touch is acting weird instead.
And last night I stopped it from rebooting, I pressed the power button to turn of screen when it frooze and that cancelled the reboot. But after that I noticed some apps with camera didn't work.

I think something like a Tool to format the entire system partition will be useful but in your case I think it will not help much.

Well now I have wiped the phone using cvm. And I flashed 4.3 instead hoping the phone will be stable. If it ain't it's going in the bin
I do miss the emoji keyboard, but that's about it. Know if it's possible to get that on 4.3?
Phone feels alot faster on 4.3, the camera reacts faster and tbh the pictures look better. No problems so far, hoping it will work. Battery time is also ALOT better!
