[Q] Root and ROMs - Xperia Z Q&A, Help & Troubleshooting

Hi!
I want to root my Xperia Z, but I am afraid of lose my warranty.. I am new to Android, I have been a iOS user for years..
Well.. My question is: Can I root my phone without losing my warrany? If I root withous unlocking the bootloader and do not install any custom ROMs? If so.. Will I be able to run "root apps"?
Thank you for all answers
(I know there may be a few grammar/spelling mistakes, but I am norwegian, so do your'e best to understant )

Rooting without unlocking the bootloader will not invalidate your warranty.
Even if it did, there are ways to return your phone to a factory state with no trace of root if you need to send it in for repair.
Yes, rooting is enough to run root apps (maybe busybox is needed, but most root toolkits install it anyway).

Im not sure what the advantages is to unlock the bootloader then obtain root, now as there is a way to root without unlocking bootloader..

So read under android development
At a guess unlocked boot loader will allow installation of custom roms
Root will allow running software that requires root like root explorer

Are there any ROMs worth installing yet? I feel like its a lot of bloatware that I dont need are installed with it so it would be nice to clean it
i think everybody that even visits xda know what root is, but unlocking BL vs locked prior to root?
if it`s only the custom roms that cant be installed I`m keeping mine locked and just gonna root. im quite happy with the stock rom.

You can install stock based ROMs with a locked bootloader, as long as you stick to Sony's kernel.

Some questions from a first timer

Until a few days ago, I didn't want to do anything involving rooting with my Xperia Z just in case I messed anything up but since Towelroot came out, I went ahead and used it to root my phone without any problems but now I have some questions.
Now that I have root access on my phone, if Sony releases an OTA firmware update, does this close the root access?
My next goal with my phone is to try and cut out as much bloat as possible from my Xperia Z but I'm worried I might get rid of too much things that I might render it bricked. Is there some things I should leave well alone?
Also thinking about trying custom roms but I'm overwhelmed by all the guides so are the guides even from years ago still valid in 2014?

Updating firmware will remove root
If you remove system apps you wont get OTA
Custom roms require unlocked bootloader which will void your warranty and you wont get OTA
Look up in the forums for latest guides
OTA shouldn't remove root. Root gets removed if you flash with flashtool, sus or pcc

If you remove something wrong, just flash a ROM again. But like always said: Don't remove something, if you don't know what it is.

How to unlock bootloader for custom ROMs: http://forum.xda-developers.com/xperia-z/development/tutorial-xperia-z-zl-bootloader-t2153261
Don't forget to make a TA-Backup!: http://forum.xda-developers.com/showthread.php?t=2292598
Quote by devshaft from the TA-Backup thread:
Backup TA can backup and restore the TA partition of the device. When you create a backup before unlocking for the first time, then you will be able to restore to full factory state (including a locked bootloader). This means all DRM keys intact, Bravia Engine working in Album and last but not least your warranty when needed

Like androidtweaker1 said, unlocking the bootloader will void your warranty. The TA-Backup includes some unique data from your device(!), which will be removed for ever if you unlock your bootloader. That's why you should make a TA-Backupfirst, to keep this data.
There are 2 ways how SONY take a look at it if you unlocked the bootloader:
- They take a look in the servicemenue
- Or they take a look at if the DRM-keys(which are included in the TA-Backup) are in your device
If you relock the bootloader only, they will see in the servicemenue that it is locked. But if they take a look at the DRM keys and they aren't available, it's clear for them that you unlocked your bootloader.
If you want to send your device to a repair center, just relock the bootloader and restore the TA-Backup. There are also some threads about it, so don't be afraid to search for it. And one more thing: Never, and really never restore the TA-Backup from an other device, it will hardbrick your phone!

Unrooting Z1

Hey, does anyone here know that if I root mybz1 and I notice somekind of problems in hardware or something. Ofcourse my warranty is voided since I rooted my phone, but if I unroot, will there be any kind of "fingerprint" of root or will I be clear with simple unrooting? I heard that samsung had somekind of counter that is unable to reset etc. So the ppl who repair phones will see that you have rooted it even you unrooted it. So long story short, if I unroot my phone will it bring back the warranty?

Rooting does not void warranty, only unlocking the bootloader does.
To unroot just flash a Stock FTF, there is no sign of root after you do this.
Thanks! And to spoil everything.. What is ftf? ?

Find them by searching for the FTF mega collection thread in the general section. Its not to hard to find.

[Q] Downgrade from 4.4.2 to 4.3 possible without unlocking bootloader?

Is it possible to downgrade to 4.3 without unlocking the bootloader?
I really need root but I can't unlock the bootloader since I need the warranty too.
Thanks!
Hi, I could be wrong, but I believe even with having an unlocked bootloader, you wont be able to downgrade to 4.3. You should however be able to root once you unlock your bootloader. Sadly, I believe there is no method currently of rooting your tablet without unlocking it. What do you need root for?

Thanks for your answer, that's what I thought. I did find a guide for downgrading to 4.3, but it seems that it's only working with a unlocked bootloader.
I use root for things like Xposed, Titanium backup etc.

Hi, do you mind linking me to that forum that shows you how to downgrade? I am on 4.3, but I am curious about trying 4.4.2 out and want to be able to bail out if I want to

Rooting noob here...

I just want to root my HTC Desire 510 in order to use Xmod game assistant and just to delete bloatware. I tried using kingoroot, it said success, but it actually didn't even work. I found out that you need to unlock the bootloader. I don't really want to this, i have no interest in it. I was thinking of using Kingoroot's HTC bootloader unlock to unlock it, then root it using the kingoroot rooter, then re-lock the bootloader with the Kingoroot bootloader program. Is it risky? Please note my phone has no important data, it's new. And I do not want to install anything custom. Just get xmod and remove bloatware. That's all I need.
Would this all work? Please help.

No this won't work and the number one reason is because if you root the phone and then spend your time deleting all the bloatware you'll be wasting your time if you don't install a kernel with write protection removed because as soon as you reboot the phone will reinstall everything! So you need to unlock the bootloader and then install the custom recovery and then make a backup first before doing anything else and then install the kernel with write protection removed and then delete bloatware!
Ok, I decided I don't want to remove bloatware. I am just rooting so I can download Xmodgames and such apps that need a rooted device. No custom ROMS or anything. Would I be fine?

Yes. Although be warned rooting will restore the phone to stock after unlocking the bootloader.
Can you even use the phone if you make changes? What I mean is isn't the point behind a locked bootloader to keep changes from being made? So if you unlock -> make a change (rooting for example) -> then relock .... doesn't that equal bootloop when the bootloader notices you've changed something?
For my two cents... I'm probably more of a noob than you @uRager, and I got through the unlocking and rooting process with not too much trouble. I think the good old fashioned way will probably serve you the best. And there are several kernels that are just a modified version of the stock kernel (write protection removed) so a couple more minutes will get the bloat removed as well. Also don't be afraid to ask questions, from what Ive seen they usually get answered.
