    So I was reading about the upcoming (maybe) 2.2 OTA. The poster said something like, "Make sure to root with Unrevoked forever before installing the OTA, or you might not be able to root again (at least for awhile)".

    Is this true?

    Can I root with "Unrevoked Forever" and install the 2.2 OTA (not a leaked version, but the actual version that actually comes over the air?). I don't want any custom roms or custom radios or anything, just the 2.2 OTA and the ability to install custom roms in the future (namely 3.0 if it ever comes out).

    So do I need to use "Unrevoked Forever", or risk never being able to root after installing 2.2 OTA?

    I think you have to have your phone untouched in order to receive anything OTA.

    You can root with Unrevoked 3 to get your custom recovery, then apply Unrevoked Forever and then load the official OTA when it comes out and revert back to a custom ROM afterward.

    Nah, I think you just have to be running the Stock ROM.

    What about stock ROM, stock kernel but with Root? Can I still download the official 2.2 OTA?

    I'm speculating here, but my guess is yes. I would assume you could download the official 2.2 OTA even if you were on the stock rom and a hydra kernel. My guess is based on the fact that the 2.2 OTA is a ROM update. The OTA will check your phone's software, and if it matches the stock software, then it should allow you to download it. Of course, this MIGHT remove your root privileges unless you have Unrevoked Forever installed.

    But once again, this is all speculation because there has not been an OTA released. Rest assured, the devs are INCREDIBLY awesome (see what I did there ;) ) and if/when this 2.2 OTA gets official, we will have some serious answers. In the mean time, if you're rooted, just install a 2.2 ROM, it's really simple to go back!

    I believe you are going to need the stock recovery in order to accept the ota.
    If you have s-off i believe the process is fairly simple but I have not done it.
    you can also follow the old procedure to unroot if that is easier.

    Same here. I have not done it either. But I remember that the stock recovery is all you need (from what I have read in XDA forums). You need to create your own PB31IMG.zip file which will include 2 files: android-info.txt, and recovery.img. The recovery.img file is the stock recovery image extracted from the RUU. And the android-info.txt file is a standard file for the incredible. But you must have s-off to use this method. Then you should be able to receive the official OTA. Someone already did this and posted it for download, except I can't remember specifically where I saw it...sorry...

    UPDATE: Found it. Here is the stock Eclair recovery. Compliments of Adrynalyne.

    so it would be safe to root first then so I can have root after the update?

    Let me take a shot at this, as i think i finally have it all figured out.

    unrevoked forever is not root. you need root via unrevoked3 in order to run unrevoked forever.

    without unrevoked forever, say you root your stock phone. you have 2.1 and root. then you accept the OTA upgrade. now you have stock 2.2 and you lose root. you now have to wait for the hackers to find a way to root the stock 2.2.

    now say you install unrevoked forever, you still have stock 2.1 and root. you accept the OTA upgrade. now you have stock 2.2 and you lose root. BUT you dont have to wait for the hackers to find a way to root the stock 2.2, because the unrevoked forever has done the dirty work and you can easily regain root.

    now that's the common thought about how unrevoked forever will work with the new OTA upgrade (that may or may not come anytime soon). but truthfully no one really knows.

    i currently have the stock 2.1 with root, and i'm going to decline the OTA until i hear people report on their experiences with unrevoked forever and the OTA upgrade. if there aren't any major issues, i'll do the Forever and then accept the OTA.

    does that sound about right?

    that makes sense I will just root tonight because i have been waiting to root but if unrevoked forever works like it sounds like it does I should be good to go when 2.2 comes out. Thanks for the clarification

    Once you root, you no longer have the stock recovery. But you need the stock recovery in order to receive the OTA. And if you install the OTA, without having run unrevoked forever first, you're stuck until someone finds a way back to root.

    Remember, as long as you have run unrevoked forever and your HBOOT is "s-off," you're set forever. Then just re-flash the stock recovery (from within HBOOT) to receive the OTA. Then you can re-root after the OTA.

    Some people hesitate to run unrevoked forever (s-off) because there is currently no way back to "s-on" which is where you want to be if you have to return your phone under warranty. I.e., setting "s-off" voids your warranty.

    Yeah, that's what stopped me -- stock is fine for me now, but I want the option of rooting in the future. I think when the 2.2 OTA comes (if it ever does), I will hold off for a couple weeks and see if it can be rooted before I decide.
