[Q] Keeping root from 4.1.2 to 4.3(109) with Supersu Pro

I'm still on a rooted 4.1.2 and have the second OTA update to 4.3 (.109) in my notifications. Rather than go through the whole flashing process, I wondered if anyone had successfully used the Survival mode in SuperSU to retain root from this point to .109?

you can try ot yourself,.but i reckon it will give you error while applying update.

Yup, I'd read similar. I was more concerned that it would update but I'd lose root, so have to then do the full process.

I have a rooted 422 with su pro, The update process aborts mid way and the OS is left untouched, leaving all as it was. I am just too lazy to do the flashtool thing and all, so I left it alone.
I was able to go from 412 to 422 with the OTA and keep root.

I know, so lazy, if I wait long enough 4.4 will come around and that might keep root!
Nobody's read a successful account of this working then? I may as well just try it and see...
Possibly
If you have bought Supersu pro then you could try survival mode, provided that your phone is only root and doesn't have a custom recovery installed.
I personally haven't tried it on my tablet but on other phones like G2, OTA update retains root.
If you have CWM or TWRP installed then it won't let you update.

Judging by all the posts I have read here so far, attempting to update to 4.3 via OTA will fail if your tablet's current firmware has been modified to have root access. Having SuperSU Pro installed with Install SuperSU into /system and/or Survival mode enabled does not help. I have attempted an OTA update with 10.4.B.0.577 and 10.4.1.B.0.109, and the update failed in both attempts. It's okay with me though. After reading about 4.3's bugs and seeing its UI, I don't really want to update to 4.3 anymore.

you're right, but besides bugs introduced as every firmware does, some very positive tweaks were done "under the bonnet" like TRIM enabled to make less wearing of flash modules, and some performance tweaks noticeable not only in launcher, but mostly in games too.
So if you have root and recovery installed you can backup your data and install .109 prerooted firmware to evaluate it yourself.

I would also recommend to flash a pre-rooted 4.3 from scratch for performance and less issues, but if you have a lot of apps installed and everything set up the way you want it can be a pain in the a$#.
Also the OP doesn't want to flash. But if he can it means that the OTA won't install because he has a custom recovery.
I don't see why Supersu pro with survival mode won't work for an OTA to keep root. This is provided that a you do not have a custom recovery installed. It's kind of the purpose for survival mode and if you do a search it works with most other updates with other devices (even for 4.4.2)
It may be possible that other mods may affect the OTA especially ones which were flashed or possibly xposed.

I do not have (nor do I want) a custom recovery or custom ROM installed on my XTZ. I only have root access, which I achieved by using DooMLoRD's Easy Rooting Toolkit when I first received my XTZ back in May 2013. Since then, thanks to SuperSU Pro, I have updated my XTZ's firmware via OTA twice without losing root access. It is only with the last two XTZ firmware releases, 10.4.B.0.577 and 10.4.1.B.0.109, that the OTA updates fail. I suspect Sony's latest firmware releases include detection of root access, etc., which causes the update's failure to install.
Nope

Well, I tried it, thinking the worse that could happen is that it would abandon the install, but unfortunately it went right through and upgraded to 4.3 and I lost root
I'd put it into OTA survival mode but not into system/apps. I had no xposed or recovery anything, just root.
So there we go. Thanks for the discussion guys, hope this is useful to someone else.
How do I root it in 4.3? Any ideas?

[Q] How to update 4.4.2 root but no recovery

Hi!
I have the SGP311 with the 4.2.2 Version of Android. Back then I rooted it using the tool VRoot (i think that was the name).
As all I wanted was root for TiBackup I left it at that. Stock ROM, some modifications through root access, but I saw no need to go further.
I would now like to update. OTA does not work, either because I am root or because the bootloader unlock (which I think happened during the root process).
There are so many guides out there, some contradictory or rather relying on going from certain versions to the newest.
What is my best bet?
Unroot and Relock, OTA update, then re-root? Is there a Guide to that?
Or how do I get a recovery on there easily? Guide?
Then assuming I have recovery on, what do I flash. Sony has grown on me, so I am happy with a stock rom or something very close to it, if I can root it for my mods.
What is the least dangerous way to get this tablet up to date?
Thanks for your help!

Vroot would not have unlocked the tablet's boot loader, so are you sure it is unlocked? And have you tried using Sony PC Companion to update the firmware? I was going to recommend trying to use Sony Mobile Update Service, which I preferred over PC Companion, but it appears Sony stopped supporting it.

The OTA may or may not work, if it fails then just flash an FTF (with or without data wipe depending on your mood) and then reroot etc
Need help
I am quite new to this and I want to root my z ultra. However I am wondering, whenever there is a software update, how can i install the update cos I know that after rooting I might be unable to update using pc companion anymore. Please can you throw more light on this. Thanks

same here on SGP512...
I guess we must downgrade, root, flash recovery and then flash a pre-rooted ftf

rooting with stock?

hey everyone, im looking to root just to be able to run a certin app i need. If i root can i still get stock OTA updates? I really dont want to put a custom rom or unstable rom on.
Yes you'll still get ota updates but you'll most likely lose root if you take the update. You can root on the most recent update though (nk2), just upgrade via Odin and flash ne6 (stock) kernel, root with towel root, then flash back the nk2 kernel, here's instructions http://forum.xda-developers.com/showthread.php?t=2909352

Normally the update will download if you are rooted, but when it tries to install it errors out. But I don't have a problem with that because I'd rather watch the update for a while to see what it does and if it has any issues. Then I can odin the update when I determine it looks like there are no issues and it doesn't add any additional restrictions I don't was to live with. At that point I use mobile odin to update and keep root at the same time.
