Got the wife a Tab 3 (10.1) for Christmas. On boot up it wanted to perform an OTA updated. I set to ignore then proceeded to root/adblock/etc..
Should I take the OTA update or disable it altogether? If so, how? I use OTA blocker on my S3, but it looks like it is just for the S3.
I probably will never replace the ROM since it is the wife's, but definitely want to maintain root access and make sure any root/ROM exploits do not get patched.
It is OK to update. You can still flash a custom recovery and root. One warning is to avoid the decrap script. Read all the comments on that thread in the 10.1 dev threads. -- Bud

By the question you can tell that i'm rather inexperienced at this, but a buddy of mine(who has a Droid on VZW) and i were debating whether or not doing an OTA update after you root would cause you to loose your ability to root forever.
I guess it's different on both devices, but he contends that he could unroot his droid, which is running a custom 2.2 ROM, install an OTA update, decide he doesn't like it, then just go back to a 2.1 RUU from VZW or Motorola, and then re-root.
Everything i have read here about the EVO indicates that if i am already rooted, and i accept an OTA update, then i will never be able to root again. Does never, really mean never? Or is it just mean that i won't be able to root using the current methods to root the phone?
What if i had never rooted and then accepted the OTA 2.2 from sprint that may be coming this week, would i then be able to root?
What exactly does the update do to remove the ability to get /root access to the phone? Something with the bootloader, HBOOT, or what?
Thanks for the information. Hopefully, this will settle this question for my friend and I.

OTA updates typically break any existing root methods, and disable any current root access.
Some OTA's also update the phone in a manner which prevents older official roms (that have working roots) from being reinstalled.
At that point, you have an updated rom with known roots removed, that can't be rolled back, so the only option is to wait until another root exploit is found and released. Which may or may not happen depending on the device and whoever is working on it.
Hope that helps.
You can take and accept as many updates as you want....you just have to modify that update by replacing the new hboot with the engineering one.....that way you can freely flash zip files
HTC is tricksy and they dont let you roll back after the OTA. Motorolla may not have this so your friend may in fact be able to roll back to 2.1 (however he may be misinformed as well).
To root basically they find a bug to exploit that allows us to gain access as a root user. when the OTA updates come out 99% of the time they will fix this bug. HTCat least blocks roll backs so now you are on a new version of the software that you can not go backwards and the bug to root is no longer there.
While there are normally other bugs that can be exploited to get root it is possible that there isnt one or that if there is no one can find it. if they cant find it then it could remove your ability to root permanently.

while true accepting an OTA will not give you the chance to do this for most.
ok, that explains things a little better. thanks.
I'm new to all of this as well. My EVO has already been updated OTA by a Sprint employee while I was purchasing the phone. From what I've read it looks like I'm SOL until someone cracks 2.2. One quick question though... How long did it take people to be able to root the first software on the EVO's?
I m a bit confuse about Exynos Abuse, I rooted my phone about a month and half ago with Exynos Abuse but I have a huge question, when an official update comes how can I unroot to update? or can I be okay without updating? Please some help would be much appreciated.
As long as you still have stock recovery....my advice would be to grab ota rootkeeper from the market. Backup root and either temp unroot with it or use Supersu to unroot. Grab the OTA and use ota rootkeeper to regain root privileges.

Alrighty, thanks for the advice! I shall do that.
A forewaring; Some "official updates" by AT&T are patches that remove certain exploits that allow us to do what we do with our phones, such as rooting and custom ROMs. Just because AT&T has an official update, it does not necessarily mean it's a good thing.

Sooo you are trying to say I can be okay without doing the update? because in that case I would be more than happy to not unroot my phone lol.
The AT&T updates are unnecessary with what we do. The ROM we're using is actually further along than what AT&T is willing to give us in terms of updates. If and when AT&T gets around to giving us 4.2, we will probably be moving along to 5 already.
If att pushes an update chances are there will be a cwm/twrp flashable version of it in the development section in a day or two:thumbup:

Alright, thanks guys!! btw Hi Sheperd.
yep, accepting OTA updates is the mortal enemy of anyone who enjoys the "treats" that we get here on XDA...there is NOTHING in an OTA update, that wont get baked into the custom roms here, if it is anything that will make our phones better..
avoid them like the plague..

Lol ok sir I will avoid them. I was just wondering, I just wanted to make sure not to do something wrong.
Hello, this is my first android device, so I'm not too experienced with the whole rooting thing. My device is currently rooted with the original firmware that came on it. (Galaxy Tab S 10.5) not quite sure which version is on here or even where to find out. I tried to do an over the air update and it wouldn't let me because the device is rooted, but apparently there is a new firmware version out, so I definitely want to get on that.
How do I go about getting the latest firmware installed and getting my device rooted again?
Thanks!
How you rooted it the first time, just repeat the steps again.
Well to get an OTA as far as I know you will need to un-root and try the update, BUT if you rooted with Chainfire method probably is gona fail, because that method trips knox, and the update is going to fail.
If for whatever reason you can update, you might loose root and maybe the exploit that worked with your current build this time is not going to work.
To find out what build you have, go to settings>>>general>>about device and there it's
That's why once you root you have to block or deny the updates until the people here with more knowledge report that it's safe.

The build number says:

I haven't tried it for marks but auto update via Kies should work. Even if rooted. Does not affect root. And does not factory reset. i. e. you get same effect as OTA.

can anyone confirm this?
I want to get some of the bloat off my Galaxy Tab S (WiFI only 10.5" 32GB) and have it auto sync time to NTP. Pretty weak that it can't do the latter on default software. I see the lovely Chainfire root tool in the General forum for this device.
My best guess is that I will still receive Android updates but installing one will void the root and make me re-root. This from a two year old thread here: http://forum.xda-developers.com/showthread.php?t=1814093
Install Titanium Backup, freeze half the stuff that comes with it, how could life get better?
Im not sure about reciving an ota update from the device will make you lose root. I have supersu pro and turned on survival mode in case I lost root from an update. To update I think you will need to flash and stock updated rom and reroot. I am on rooted stock rom and have twrp recovery. I also changed my status to official so I can see if their is an update. So basically I can get the ota update and install it but I have not tested it yet with the new update yesterday. Since im on a custom recovery and rooted Im not sure if the ota update will install correctly. But to answer your question Im pretty sure you flash the rom update with odin. As for ota updates and installing them i do not know. Hope this helps!
I used the KINGOROOT technique to root my SM-T800. I had to downgrade to firmware T800XXU1ANF8_T800XAR1ANF6_XAR (ANF8) to allow KINGOROOT to work.
The SM-T800 is now offering an OTA update. The only detail provided is "Size 39.96 MB" No clue what version it is.
Is there any way to determine what version of update would be loaded?
Would root be maintained?
I have purchased SuperSU Pro, and enabled "Survival Mode", which says it "attempts" to keep superuser access across OTA updates.
Can anyone confirm whether SuperSU Pro's "attempts" are actually successful on the SM-T800?
Once rooted you should disregard small updates.
You never know what this update will do. It could do anything from something simple to locking your bootloader. It won't be the first time people have ended up locked out of their device after an update.
If you really want to flash it, let it download then flash it with FLASHFIRE.

I wasn't thinking of the small updates - I was going jump ahead and flash the latest stock Lollipop (T800XXU1BOE2_T800XAR1BOC5_XAR) Android 5.0.2?
At this point I've got the tablet usable with KitKat - thanks for all your help!
I won't have time to mess with it for a few weeks probably, so I'll defer the Lollipop update till then.
I guess I have already let it download something, although it doesn't say what. However, it is nagging me to install the OTA update all the time. So how can I
1) Capture the downloaded update file?
2) Find out what version it is so I can decide if I want it?
3) Stop the nagging to install the update?
If you're going the whole hog then just flash Lollipop with Flashfire and you'll keep root.
