Return to true stock after full root

Hi all, lurker turned poster here. I've been looking around but i can't seem to find a straight answer to this.
If i were to go through the process of doing full root and NAND unlock, to install a custom ROM and test, can i return to a true "stock" setup, specifically re-locked NAND so that my EVO can be returned under warranty? I know that RUU returns me to stock kernel and ROM, but I can't find anything about the NAND. I'd prefer not to go any further with testing any custom ROMs without knowing that I can return my EVO. Thanks in advance!

Yes flashing thee stock rru and you are back to stock.our just install the latest update and presto no more root or nand.

EVO fully rooted fresh

OTA Froyo 2.2

I'm at a loss, as I remember reading it but can't find it any where to verify. When Sprint releases 2.2 Aug 3rd, since I'm rooted I should NOT accept OTA or force it to update...or ever do it, right?
Sorry for the dumb question, just wanted to make sure!

You should not.

thanks for the quick reply!

hi im using unrevoked3, how do i go about updating to froyo 2.2 when it comes out OTA? thanks!!

you dont until someone here roots it.

And go ahead and get off unrevoked now. Do a full root and use a rooted rom even if its a stock rom. You will be happier in the end. There are several methods posted in the Dev forum. Just pick one that matches the sweet version your currently running or follow the instructions posted previously in this forum.

Actually, I don't recommend full root if you can get by without it. Full root permanently screws up your PRI, even after unrooting. Until its fixed, people should only do it if they absolutely need it. You can use an ota update, but you will lose root until someone finds a way to root 2.2. Also, you can flash one of the stock 2.2 roms that are rooted. They should work with unrevoked.

It doesn't screw up your PRI, it just makes it a lower version. For some people this causes lower speeds on 3G; others are fine. But yes, once you do NAND unlock your PRI is stuck like that until someone figures out a way to update it.
I think flashing a 2.2 ROM with unrevoked and expecting it to stay rooted is a risky thing to do. I wouldn't recommend it personally. That is, unless someone has tried it and it works.

[Q] Downgrading from froyo

Im new to this forum and I had a few questions about downgrading from the stock froyo 2.2 back down to 2.1, I installed it manually I was wondering if there is any way to do this?

As of right now there is no possible way. But give it time.

i'm looking to downgrade as well if anyone hears of anything!

I was reading about someone downgrading their nexus one froyo back to eclair using andoid sdk and some rooted sign file and a recovery file. Lucky nexus one users lol.

Anyone know anything about this?

if you want to downgrade then wait, it took a long time to root the last OTA.
If you want to upgrade and keep root, NEVER accept anything from sprint, only install from XDA or a similar forum.
The fact that this is an entire OS upgrade can either be a good or bad thing in how long it's going to take to root.

Look at it this way: If you could downgrade to 2.1, there would be no warnings or questions about how to root after flashing the 2.2 update. The answer would be "downgrade to 2.1 and root it like before."
But once 2.2 is rooted, you will most likely be able to flash a 2.1 stock or custom ROM if you wish. Just make sure you flash one that's pre-rooted.

Thanks for all the info guys, I wanted to downgrade to run cyanogen mod and overclock etc.

[Q] Anyway back to 2.1 or root 2.2 updated?

After just getting my Evo recently I was overly anxious to get Froyo so updated it quickly not knowing that standard rooting methods wouldn't work on it. I was wondering if anyone has found a way to go back to 2.1 or a way to root the 2.2 to install custom roms ect...?

......wait for it......

eeeeew. Who wants to do that?

[Q] Rooted 2.1 w/ custom ROM to 2.2?

I'm pretty new to all this rooting and ROMs and everything, but at the moment, my dinc is loaded with 2.15 radio/SR2.5 vanillia/S-OFF, but I want to get the OTA update for the official 2.2 android. I don't really understand how to do this, and I'm afraid I might mess something up, so any help please?!

Try it. Read and understand what you are going to do...before you do it. Then ask if you have any questions!

Well I'm able to go back to 2.1 sense, but I still have the 2.15 radio. Can I update from the official update with the new radio, or do I have to downgrade it back to 1.x

You have to go back to the stock radio. That's part of what the OTA is looking for. If you have an upgraded radio, it's going to skip your phone.
