[Q] Can I root but stay official? - Android Q&A, Help & Troubleshooting

I have a Sony Xperia Z Ultra, running 4.4.4. Is it possible to do a simple root (in order to make adjustments to the LED and sound), but not affect the stock ROM or over-the-air updates? I don't want to miss out on the official Sony Lollipop, so should I maybe wait to root until after that update is released? Thanks.

No, you can't get offical updates if you have your device rooted , although you can root your device till the new update is on the line. Just unroot your sony device get the update and then root it again. Otherwise try any other rom.

Ah, many thanks. I didn't realise that was possible. I thought rooted was rooted and there was no going back. Although I've rooted a couple of devices before, I'm still something of a newbie. Would you be able to point me in the direction of a good tutorial or website with instructions how to do a basic root, and un-root, on the Z Ultra? Cheers.

I found it pretty helpful , instructions are simple.

Is there a reason as to why google doesn't allow OTA on rooted devices?

OTA update to 6.1.A.2.45 for rooted Xperia S with unlocked bootloader

I have a rooted Xperia S with unlocked bootloader, by following instructions on this thread.
Today I received a notification about OTA update to 6.1.A.2.45 (40MB in size) and I was wondering if I can apply this update without loosing root. I really did search for an answer on the forum before making this post and couldn't find anything specific for my phone, but what I did found only confused me more, which is to be expected since I am a noob. Apparently it worked for some users of Xperia Play with unlocked bootloader, but on the other hand some users of Xperia Arc S say that bootloader should be locked when making an OTA update.
I would really appreciate any help from more experienced members, I'm new in Android and don't want to start by bricking my phone.
Thank you for your time and effort.
Boom
better dont, you will end up with a bricked device. NEVER accept OTA updates if your bootloader is unlocked.
Don't update with PCC when you're unlocked.
Wow, that was fast! Thank you guys.
hi, did you find how to update?

i also have an open bootloader although not root, but i tried updating using the phone's OTA and PCC and neither worked. I promptly realized it might just be the open bootloader which is keeping me from updating, so how do we manually update? if you have any procedures will highly appreciate anyone..... thanks in advance

You can find your regions FW. (firmware) and download it, after that download and install flashtool, and flash the .ftf file via flashtool and that is it.
thanks for the quick reply

Im going to engage in a rather noobish conversation but i want to be completely sure before i proceed to install. my phone and my pc companion both find the update which is 6.1.a.2.45, which i assume is the one i need to find on .ftf. after downloading it from wherever i find it i just open the flash tool program and select it to start the installation? and again thank you

they have some firmwares there, but they seem to be full updates, because they are 300+mb while the update on my phone its only 40mb.

Hmmm,
Slightly different scenario here.
I have a rooted xperia S with a locked bootloader and obviously want to preserve root.
Previous experience tells me that a PC update from SEUS does a full wipe of the phone and looses root however OTA updates usually preserve root. I was hoping somebody could clarify if this is still the case?
Thanks
if your bootloaders unlocked you cant update ota or via seus. it will just give an error about your device being modified

there is a rom somewhere in another forum i guess which already is updated and rooted. so you might want to just download that one and flash it. it has its own kernel and recovery.

I've not been on much recently at all so I could be wrong, but I'm sure it's been said that you can flash ROM such as the linked one when bootloader is locked and perhaps the pre-rooted one too. May need to search the thread.
Nothing out there that allows me to root my Xperia S on ICS without wiping my data though I think. One can wait... or dream. :[

Yeah having too wipe at this point is a bummer. If I'm going to wipe my phone ill wait for the ability to unlock my locked bootloader.
Problem with that is I will most likely have a new phone by then.

When/who made root for 4.0.3 5a OTA?

I know that the guys that are making the modds here for the Sony Tablet S they said that for the moment there is no way to root the 4.0.3 5a OTA cose the bootloader is closed... but... anyone... is there another way?
I just bought the Tablet S... and without root und custom rooms is just no fun.
Thanks for your efforts and with great respect for your work.... greets from Berlin

on same boat like you , hope they can find out the way to root 4.0.3 r5a , this room got so much problem and i need wipe and install new rom stable
Yeah I have to say, I upgraded cause I was sick of getting the messages for months and months on end!
Upgraded on Sony Tablet S from OS v3.x to v4 R5.
Not sure why people call it "OTA" (over the air) when it definitely was downloaded via my Wifi!
So am I stuck? Am I locked? I thought this was the perfect device to experiement with!
p.s. How can we take a backup of the current ROM prior to rooting? Something I'd like to do this time when rooting my second device.
Cheers!

Why you didn't disable the upgrade message with condi's aio tool?
I have my tablet S with r5a rooted only because condi released the Flasher but I don't really see any diference from r5 to r5a
Why? Cause I got sick of it, and I figured the newer OS would be better!
The new OS is much better. Much faster. But several apps - I wish I could remove / uninstall won't go... Plus the stupid remote and other button at top of screen ...
Where can I find a list of ROM's that will support the Sony Tablet S device?
Anyone know?
So is 4.0.3 still not rootable, even with the latest AIO?

Where do I look to see if it is R5A? Or how do I tell? In about Tablet, Android version just says 4.0.3. It came OTA.

[Q] Rooting Ultra C6833

Hi
I'm on .510 and I just got done reading through a bunch of rooting threads and had a some questions.
From what I've read you cannot gain root access if you upgrade to .257.
If I root it now, then upgrade to .257, will my root remain intact? I have screen sensitivity issues and want to upgrade, just trying
to find out the best way possible and be able to unlocked my bootloader, and achieve root.

No, I'm on .510 but I got the message to upgrade to .257.
If you're already rooted on .510, install OTA Root Keeper (from the Play Store), then update to 257. You should (if everything goes well) still have root when it's done.
This method (with OTA Root Keeper) did not work in my case.
My Ultra has already rooted, I received the OTA update, but the update refused to install.
Every time I tried to install the upgrade, an unknown error occured and the phone restarted.
Finally, I succeeded to upgrade the software with root using this method: http://forum.xda-developers.com/showthread.php?p=46803343#post46803343
hey all, sony xperia noob here, been reading the forums but i hoped you wouldn't mind a quick question. i got a C6802 that has .257 on it, and it still has warranty until late February 2014. is there a way to downgrade without unlocking the bootloader, then root(again, w/out bootloader unlock)), and then update back to .257 and keep root with one of the methods?
or should i not even worry about the warranty? on the phone they said unlocking the bootloader does void the warranty, but you know, they have to say that i'm sure. thing is, i figure there is a chance i could exchange for a replacement if i find any quirks.
thx in advance for any info/advice.

I'm surprised

I'm surprised this device attracts so few developers. Most devices have several custom roms and kernels to choose between.
I love the device. I had some tough weeks to get use to the size but now I can't imagine having another phone.
It's perfect. I can play with it for hours.
I will send it to some of the core devs in my team when I'm done with it so we'll get official SlimRoms on it.

The answer is to read, read some more, then think about what questions you still have and search for them and read those results.

After owning this phone for almost a month as my daily driver, I can see why this phone might not be so popular.
Sony does not seem to do as much advertising as Samsung (at least that I can see), and for quite a while this phone was just too expensive. Add to that the fact that this phone for most people is just north of being too big (I came to it after owning the Galaxy note so I am ok with the size), and if you own one of these, you want to use it a lot and even with the stamina mode turned on battery life can be a little short if you turn it on to play with it every 5 min or so.... lol.
On the other hand my S4 build quality feels worse and worse after owning this beautiful thing.
One final thing I can think of is that the stock ROM (at lease 4.3 which I am still using) is not very bloated and really quite nice. I don't feel the need to try to load a AOSP rom as much. Every time I pick-up a touchwiz device I just want to throw up a little.

KitKat has already been rooted for quite some time! I am using 4.4.2 KitKat and am rooted.
Refer to Jackie's root guide. You will have to download the 4.4.2 FTF rom as well as Jackie's custom kernal in order to root.
Have you unlocked your Xperia Z Ultra bootloader? In order to root you must have your bootloader unlocked. It is very quick and easy to unlock.
Here is the link with instructions on how to root KitKat.
Special thanks goes to Jackie for making this possible so fast.

Before telling some one to unlock their bootloader to gain root PLEASE explain to then the consequences of that action:
If you unlock the bootloader before backinf up the TA partition you will lose your DRM keys and warranty. You will also lose the ablity to use some apps that rely on those DRK keys.
If you want to keep these (or have the ability to restore them) you have to downgrade to 4.2 (build ending with .532) and use an exploit to gain root

5 latest firmware and root remains

I have had my Z2 less than a fortnight but already I'm itching to root it etc, problem is it seems a lot more complicated than Samsung devices. I was always switching between roms on my S4/note 2. I am on the latest firmware and would like to root it to be able to use xposed but I'm scared of messing it up and as the phone is under warranty don't want to end up with a paper weight.
Has anyone done a detailed tutorial for newbies like myself?
Thanks in advance

It's not really that hard and there are also of resources online that can guide you.
1 Downgrade to 4.4.2 is required as noone had found a vulnerability with 4.4.4.
2 Root phone
For step 1 and 2, Have a look at this http://www.xda-developers.com/android/how-to-root-the-sony-xperia-z2-xda-developer-tv/
3 install recovery for lock bootloader
Have a look here http://forum.xda-developers.com/showthread.php?t=2785598
4 install a 4.4.4 zip through recovery. I recommend this one as its basically stock http://forum.xda-developers.com/xperia-z2/development/stock-4-4-4-23-0-1-0-167-bug-free-t2929402

It depends on how you want to root, you can root and permanently void your warrentg or you can root and keep your bootloader locked
