UPDATE: If you need to unroot your Evo 4G completely back to stock, see Unroot Evo 4G Here!!!
Nandroid is a fantastic tool for your HTC Evo 4G to backup/restore the complete system state including apps, contacts, and the rest.
For those of you who have used Nandroid (if you’ve followed all the steps in the root HTC Evo 4G guide) to backup your stock ROM, yes you can easily restore back to it.
This won’t really “unroot” your HTC Evo 4G because there’s actually no way to “unroot” your phone after rooting it BUT it will get it back to the exact same factory state. No, I don’t think Sprint can tell if you’ve rooted your phone if you somehow return it. I believe it doesn’t void the warranty when you root it and there’s no way Sprint will be able to tell unless they’ve got Android experts working for them, I highly doubt that.
So, first you will want to shut your Evo 4G down.
Then start your phone into Hboot (bootloader) mode by pressing power button WHILE holding down your volume down button.
Once in bootloader, wait until your SD card is cycled then hit the volume button down to choose “recovery” then hit the power button to enter recovery menu.
If you see above screen, you are in recovery. Connect your HTC Evo 4G via USB cable to your computer.
Run the recovery-windows.bat (for Windows systems).
Your phone should now be in the above screen.
Choose “backup/restore” then “Nand restore”. Then find the backup file you made.
Hit power and start restoring.
When it’s done, hit the power button to reset your HTC Evo 4G.
Now, you’ve unrooted your HTC Evo 4G. (sorta.)
You can use the same method to also restore any ROMs you’ve saved using Nandroid.

When i rooted the phone i didn’t get to make a recovery mode. and now my su isn’t working right since i downloaded the update.
It’s okay, u will just have to get the Nand unlocked and then next time that happens, you can always revert back to your hacked ROM in 3 minutes.
I’d like to know if there is a way to bypass the USB connection and run the script locally from the phone so backup/restore can be done on the fly without connecting up to a PC.
Yes,to your question sir,I’ve flashed rom after rom completely from me evo 4g without
Using a PC. needed apps marked,androzip file manger,stock download manager,hulufided flashplayer 10.3 from xda developers.

Can you please tell what i can do to resolve this.Thanks
Hi there, I used the website root(or not root) unrevoked.com. I say not root because on some sites I see it says that it is not really a root. Well whatever the case I am alot better at jailbreaking my ipod then I am at rooting my android. This is all like learning a new language to me. So I have not done anyhing else but use the unrevoked website tool to root my evo and download a few apps. I have not done anything with nandroid or the roms. Just when I had some time to sit down and try to learn a little bit about Androids OS I dropped it. Just one time and the cheap a** screen broke. I do have insurance but I haven’t put the claim in just yet. I still have full use of my screen but the shards of glass are coming out quick and Id like to restore as quick as possible before the screen dies completely. So i was wondering if someone could help me figure out what the best step to take next was. I have not downloaded any paid apps and I do not care about keeping any of my settings,contacts or calender events because they are all synced with google. So my main concern is just restoring my evo back to the factory settings with as little evidence of a prior root as possible. I know that there are tutorials up above but with my situation of not needing to save the current rom onto his device I was hopeing that someone could explain to me, in newb language, of what steps are best for me. Thank you in advance for any help.
I never backed up my stock rom, how do I get it back to stock with out the back up?
How can I know which file was the one I used for backup? What is it called? Where is it stored?
I used your instruction for rooting my phone.
Do you know where I can download the backup rom file for the Htc evo. For some reason my phone didnt backup correctly and I want to restore it back to the factory setting. Thanks for you help.
This is the Original Factory Rom

Jenelle,
You and me both! I just purchased a new HTC EVO 4G and am not able to “root” it. How about you?
