I have a unlockable bootloader Xperia S, but for warranty & DRM key reasons, I am currently refraining from unlocking the bootloader. I have however rooted it.
My question is, can I keep root using OTA Root Keeper, so when OTA updates arrives root stays?
You should be able to.

There is currently no root for .21 update.
But, you can unlock the bootloader and flash a ROM that is already rooted, which will give you root. But that will void your warranty (by unlocking the bootloader).
you can downgrade using http://forum.xda-developers.com/showthread.php?p=23872834 but the question is :
after rooting old version, is it possible to upgrade to .21 keeping to root mode ??
yes, you downgrade (I went to .14 because it was the only one I could find) then you root, then you download and install ota rootkeeper from the market. Then you go back up to .21 and believe me this is a complete oversimplification of the process.
DO NOT UNLOCK YOUR BOOTLOADER JUST FOR ROOT
What I want to root on .21, I must say that I am very happy that I did not unlock my boot loader. Last week I had to send my TFP with dock back to Asus as it would never charge the tablet when connected to the dock. Therefore, they quasi upgraded me from a tfp201-pad 0214 to the 0215.
Hi,
As soon as I got my cell, I rooted it. I think I read some where that x-reality wont work on rooted phones? Is it true? I haven't had a chance of experiencing it as I don't know if its running or not.
On 290 (Android 4.3), rooting requires (or used to, not anymore) that your phone's bootloader be unlocked.
It is this unlocking process that causes you to lose your DRM keys, thereby getting rid of X-reality.
Lower builds (257 and below) could be rooted without unlocking the bootloader.

I successfully root .290 without unlocking bootloader...
I use NUT's guide...
Please search around...
That's what i said - rooting 290 doesn't require unlocking BL anymore, but it used to.
When I bought my ZU 6802 it was on 257 then I OTA to 290 then 681.
my goal is to get root access only I also want my DRM key intact.
Here is what I plan to do with the ZU.
1.Downgrade to 532, root it without unlock the bootloader, then back up my TA petition.
2.OTA upgrade from 532-257-290-681(will I still be able to? I already took the OTAs Do I need to unroot first?)
3.After back to .681, I will unlock bootloader, then use jackie099's method to root it.
4.Relock bootloader, restore my TA petition.
Does that sound like a plan?
Two things I worry.
1. I am not sure if I can take the OTA update back to .681 after downgrade to .532,
2. What will happen after I relock the bootloader, will I lose root? Jackie099's rooting method has dual recovery, it uses kernel from 6833, my ZU is 6802, my guess is after I relock the bootloader, dual recovery will be lost or null, and I will still have root access.
Any advises will be appreciated.
I am a rookie with these things and I would like to get some clarification.
I want to root my tablet, I am very satisfied with it and its system, all I need is to root it without touching my bootloader and drm keys. There are so many threads about it claiming its possible without unlocking the BL and I am not sure which tutorial should I use to root my device.
My device is LTE version, nothing modified and firmware is 23.0.1.A.0.16.

you can try Towelroot as I see Z3TC is supported but I didnt test it on my tablet
where did you see that z3tc is supported by towel ? i can't find a device list or so.

There is only one method at this time to get root on this tablet and this method involves unlocking your bootloader after doing a backup of you DRM keys (TA partition). Once you rooted your device with the unlocked bootloader you can reflash the TA partition and the bootloader will be locked again with all DRM keys intact as if you never unlocked it in the first place, but with root. Towelroot is not supported as the kernel exploit that was used is patched since nearly half a year now.
Hey guys,
I own a stock Xperia Z3 Tablet LET (SGP621) and I have never upgraded it, still running stock 4.4.4.
I want to root it and only root (to Lolipop). I have read topics but there are so many and written in strange language for me I have no idea where to start.
I read I could just flash prerooted ROM without even touching my drm keys, right? But then I was not sure how could I do it.
Any help would be appreciated.
Thanks!
There is no method to root the tablet without unlocking the bootloader. The root exploit which most of the guys mentioning in these strangely written topics (giefroot, easy root tool, geohot, blablabla...) is useless now since Sony surely patched it. So to root, you have to unlock the bootloader. But wait, you would loose the DRM keys.
So, it means that you need to make a backup.
But, without root you can't backup.
But, how should you root if you don't have an unlocked bootloader??? And it goes on and on and on and on....
The "trick" is to flash a firmware from another device (not z3 tablet compact) that can be rooted via the exploit. But nobody wanta to use the "other" firmware to gain root. This "other" firmware is only used to gain root temporary so you can backup the drm keys.
Then you likely have to flash back the stock firmware (and root will be lost again).
Now that you backed up the drm keys, you are ready to unlock the bootloader and let the drm keys disappear for a while.
And then you still have to do some complex steps to achieve root on your stock firmware, then restore drm keys (bootloader locks up itself again...), blablabla
TL;DR forget rooting this device unless you are ready to do all these above steps. If you don't understand the steps and are new to rooting sony devices, I recommend you not to root and enjoy the stock firmware. Next thing is that lollipop will come and you could easily update without problems (via OTA). Until then, wait for some magicians/hackers/crackers find a new exploit which can root 2015 sony devices without unlocking the bootloader.
If you want to know if your device (firmware) can be rooted via exploit, try xdualrecovery. It contains the exploit root method. But if you are unsuccessful flashing xdualrecovery, that is because the exploit doesn't work and your firmware is patched.
Sadly, sony devices are nothing like nexus. And including this "afraid of loosing the drm keys", simply unlocking the bootloader might not be a pleasing thing to do.
just to add maybe we don't need to unlock bootloader to root our tablet
we temporarely flash z3 kitkat system to get a rootable core and we flash again z3 tablet compact system before reboot
or so I understood

I would advise not to answer questions about root without understanding the process and/or misguiding people asking for help.
The information you give above is wrong. You don't need to unlock your bootloader provided you downgrade to an explotable firmware.
The thread that details how to root your Xperia Z3 Tablet Compact is this one:
http://forum.xda-developers.com/z3-...to-rooted-lollipop-locked-bootloader-t3083980
1. Obtain root by first flashing SGP621_23.0.1.A.0.167_CE.ftf and the system partition of D6603_23.0.A.2.93_Generic_20GLOBAL.ftf. Then use giefroot to root.
2. Prepare prerooted flashable zip of 23.1.A.0.690 NOBA on your internal storage or external SD.
3. Install XZDualRecovery and now you will have TWRP to install 23.1.A.0.690 NOBA on your SD card.
You may ask any doubts in that thread.

Well, the OP (junior member) mentioned "strange languages". So he/she might not understand all this complex steps. That's why I "let it be" to keep the things easy. If he/she understands these steps then it's good for him/she. But you're right, I lied. And thanks for the clarification and pointing out my wrong information.
Personally, I had every Xperia unlocked without backing up the DRM keys. I never had any disadvantage. I was, however, a little reluctant with the XT3C. That's because I use it as both my phone and tablet.
Still, did it now. No adverse effects. Root is SO much more important than the Bravia engine or whatever. And the camera isn't very good anyway so I don't miss the 'better' quality. It's bad either way
