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?
Does anyone know if there will be a new root method for the new update samsung pushed through? (UVUAMDL)

should I use auto update if I'm going to root and install custom rom later?
For me only, once I rooted I purposely used titanium backup to freeze "system updates".
I still get normal app updates, but don't want any system updates, that may break root, until my phone is unlocked.
Ok thanks, if I update can I still root after? After the update if I do a factory reset will the update be lost?
An update can remove root, and patch the methods that a particular root uses to take effect, depending on what it does. That is why I am avoiding updates until the phone is unlocked.
By the way, I can't post on dev forum so I'll take advantage of this topic here.
I already know that Purple Drake's root is working till the V10I update.
I rooted my G3 and disabled OTA's. If I enable them again, run the OTA update (V10I) I'll probably lose root, right?
But, if I apply PD root, will I get root again w/o losing all my data?
thanks!
What is the advantage of the update, should I even bother with it?

Anyone know if its safe to install the update after rooting?
It's fine to update after root. You have to use the Smart Switch though.
If you run into a problem then just run the Chainfire autoroot procedure again.
Back in the day I used to use Voodoo OTA rootkeeper to keep root through updates, but I think that process was broken late in KitKat - is there anything like that for Lollipop which would allow allow acceptance of an OTA update and manage to keep root?
Thanks!
Sadly nothing I have seen that actually works. If you want root on 5.1.1 you need to sacrifice Knox or run an engineering bootloader and lose fingerprint reader.
