Currently, I have an EVO with the OTA update + Unrevoked3 for root. I want to flash a custom ROM, so I'm planning on going through the SimpleRoot process, but I'm not 100% sure if I'll like the result.
My question -
After making a nandroid backup from the new bootloader that Unrevoked 3 provides, should I be able to restore my phone EXACTLY how it was prior to going through SimpleRoot and flashing a custom ROM?
no, if you do the simpleroot you will end up with hboot 76.2 which is, as of right now, irreversible

I'm getting conflicting answers on this between forums. One user has told me that a Nandroid backup will return your phone to the exact state it was in at the time of backup (like a Ghost image). Are you saying that one could not load the stock ROM/RUU, restore the Nandroid backup, and be back to whatever root state the phone was in? And if so, is this because the root permissions are actually set at a lower level that never gets wiped out even between ROMs?

Ok, minus the HBOOT 76.2 change, if I restored my nandroid backup, would the vast majority of the system be restored? The HBOOT thing doesn't prevent me from restoring a backup, right?

Nandroid makes a backup .zip file full of .img's of certain partitions. For practical purposes yes, you will restore everything you see and use on a daily basis. For literal purposes, no, you will not literally return to the EXACT IDENTICAL STATE you were in if you made a nand backup then installed the 76.2 hboot or upgraded your radio or wimax.

Yes, minus your hboot, radio, wimax and recovery partitions.

Short and sweet:
1. I'm using the recovery that comes with Toast's 2of2 method (this is Amon Ra?) The Nand/ext backup fails for me and I read in a thread that's expected, but I can't find it again with the forum search. How would I fix this, and is it necessary? Is the regular Nandroid backup good enough?
2. Does a Nandroid backup include the kernel? If I push a custom kernel and have problems, will a Nand restore revert me to the kernel I had when I made the backup?
Thanks for the help in advance.
yes and yes
the ext bkup fails bc you dont have a ext partition yet
1. Do you have an EXT partition on your card? If not then you can just use the straight Nandroid backup.
2. Yes a Nandroid should back up the kernel at the point you made the back up. (not 100% sure but 99% )
I hate to hijack the thread but it looks looks like it died down a little and in my search effort this is the closest to what my question is. so to save making a new post on something probably answered before.
I am a relative noob. (i know sad) but i am learnign fast. I was wondering what exactly a nandroid back up does and does not back up.
I am doing the Starting over method to get back to stock 1.47(rooted) to see if it fixes 4g and think i can just nandroid after doing the method described to get my rom back etc. My only fear is that by nandrioding what ever benefit i got from starting over will be reverted.
Srry for the long explaination but basically if i Nandroid is it basically a complete image changing literally everything back to the previous state(ala HDD img)? If not will doing the starting over method then nandroiding revert me back to having the problem again?
Thanks in advance.
Nandroid backs up your entire system config. Radio, software, kernel, rom, etc. As long as you don't unroot, your system will be exactly the way it was after you restore.
Omega, if you do the back to stock root and then restore Nandroid, I'm pretty sure it will be as if you never did the back to stock. Pretty sure but not 100% positive.

Nandroid does NOT back up or restore your radio, wimax, boot or recovery partitions
AFAIK nand only backs up your system and userdata partitions, not positive about the cache or misc partitions.

Thank you very much. This should mean that once i do the starting over i should then be able to just nandroid back to my rom without having to redo my kernal/theme/rom and it shouldn't mess up my wimax radio again.

Correct .
*edit- looks like I'm wrong about the boot partition. I just unzipped a nand and there's a boot.img in there.. still shouldn't affect radio or wimax though
If I run unrevoked3 on stock 1.47 (new Evo), can I restore a rooted 2.2 nandroid backup from my first Evo that was made with Amon_Ra? Would it work without engr. hboot? If so, could I be in trouble later by going to this rooted 2.2 backup w/o full root?
Had to bump this because I was curious to see how to restore a nandroid backup if I were to get a new phone for whatever reason.
Is it as simple as putting the sdcard from the old phone into the new rooted phone and performing a restore (assuming the same recovery method is used in both phones; in this case clockwork)?

It should be. the hardest part should be rooting your phone.
I'd like to try out a ROM or two. i was just wondering what would be the best method for backing up my phone before wiping/loading a new rom? I've seen several mentions of nandroid backup, but i haven't found a link yet as to how to use that.
Will the backup restore the ROM i had when i created the backup? Or will i have to flash that rom back on the phone and then run the restore to just get my apps/data back?
thanks
You can make a nandroid backup in your custom recovery. And the backup will restore your phone to how it was the moment you made the backup.
How do I do a custom recovery?

you are rooted and have nand unlocked, correct? if so, what method did you use?

rooted yes, not sure about nand. I used unrevoked to root the phone. I don't think unrevoked does the nand unlock. I'm not even clear on what nand unlocking is. So i hadn't looked into doing that yet since i didn't want to unlock 'it' until i knew what 'it' was
In for this answer... I titanium backed up but need to know if that's enough.
Ok - played around with the power btn+vol down menu and found nandroid and i am running a backup now.
What exactly is this backing up?
If i were to reinstall the original ROM from sprint on here, could i use this to restore the phone as i have it now? I assume i'd have to root the phone first in order to use the restore the backup?
thanks

1. It's backing up your nand.
There's an above post explaining this already.
2. Not necessary. Fully understand the answer to number 1.
3. Didn't you already root? You couldn't be doing this stuff otherwise.
I know that I have seen this question asked before but I can't find the post. I broke my evo (let's call it #1) and I am trying to restore evo#1 CWM backup onto evo #2 the new phone that I just got. I have put the sdcard from evo#1 with its latest backup into evo#2 and have booted into recovery.
I remember seeing that you can't do a full restore but rather to use Advance Restore but I don't remember which components to restore and which not. I think that I restore all but WIMAX bacause WIMAX is different for each phone.
Anyone know ??

Generally, I don't believe it's recommended to restore a backup from one phone to another. However, I've seen reports that it it can be done. As you assumed, you are correct by NOT restoring the wimax. If you were to do that, it would restore the RSA keys of your old phone, overwriting your NEW RSA keys. You don't want to do that. So remove the wimax.img from your nandroid backup before you restore.
Also, I'm not positive on this, but I do believe that if your old backup was made on a certain hboot version, that you need to be on the same hboot version when restoring that backup. (lets say you when you created the backup, your hboot version was 2.10, then when you restore your backup, be sure the hboot version on the new phone is also 2.10). The reason I believe taht to be true, is because I had always had hboot .93 on my phone, and all backups I had ever made were when I was running .93 hboot. I then downgraded to the ENG .76 hboot, (to use fastboot), and I tried to restore a backup that had been created when I was on .93 hboot, and it did not go well. After the backup restored and I rebooted, it booted straight to fastboot, and that was the only place I could get. None of my old backups would restore. I then switched back to hboot .93, and my backups restore perfectly fine. So that is what led me to my conclusion. Good luck with your quest. ( i personally recommend just starting fresh, and not restoring an old backup, just to be safe)
k2buckley got you covered, but restoring a backup from an old phone to a new one WILL cause you problems, and the easiest way to avoid it is to not do it.
The best you can do is backup your apps via titanium backup and your launcher settings, transfer those folders to your new phone. When restoring the apps, do only app and data, NOT system settings.
Thank you both for the reply. Based upon your feedback I decided to do a clean install of everything.
You're welcome; just trying to make it smooth as possible.
I had my Evo (android 2.2) rooted with unrevoked forever but had to take it in to Sprint. I unrooted with the S-ON zip and then flashed the closest PC36IMG.zip that I could find on the forums. Finally, I did a factory restore and applied the OTA (3.70.651.1).
I've got the phone back now, but ever since the flash my 4G refuses to connect. I suspect I might have messed up my RSA keys.
I have a recent nandroid backup, but I'm afraid to restore it because the PC36IMG.zip updated my radios. My question is: is it safe to restore?
I'm aware that I'll have to re-root and install clockworkmod again.
I'm a long time reader, first time poster, and I appreciate your input
Heck, if you're able to re-root, it wont matter. Once you're S-OFF, simply reflash the radio, PRI, NV & WIMAX that you had before you unrooted and then restore your nandroid backup. You *should* be fine afterwards. By the way, the radios are independent of roms so it's not like your baseband, PRI, NV & HBOOT was backed up when you made your nandroid backup with the WIMAX being the only exception and that is if it was selected to be a part of the backup. Having said that, if you are not able to re-root then I would not attempt to restore a nandroid backup.

Alright, thanks! I won't be able to downgrade the hboot, but I'll give it a try nonetheless. I'm assuming that bricking the phone's unlikely as long as the downgrades themselves are successful. I'd just have to reinstall what I've got now if the backed up ROM is incompatible, right?
Edit: I've got the wimax.img in my nandroid backup
If you have the OTA, and its s-on as you said, you can't root it as of yet.

Do you know which OTA that was? I have a feeling that I didn't get the latest one, since I'm not on Gingerbread.
I did get some strange results after running Unrevoked - I have S-OFF but I get the red triangle/exclamation point when booting into recovery and I don't have root.
If you are S-Off then you just need to reflash the recovery. Once you do that you should be able to reload your nand backup.

It seems like you do not have a custom recovery flashed.
User ROMManager to install Amon or Clockwork.
As long as you are S-Off still, then you will be able to reboot into the recovery of your choice.(Didn't see you didn't have root)
Try rerunning UnrEVOked.

You don't have a recovery; http://dl.dropbox.com/u/19699565/PC36IMG.zip Download that, place on the root of your sd card, boot into the bootloader, apply update, reboot, reboot in recovery, and you'll be on Amon_ra 2.3 recovery.

I've tried UnrEVOked three times, all to no avail. Still the same result.
And yeah, I tried ROMManager + Superuser from the Market but they didn't work. Definitely no root.
I figure that I should be able to push clockworkmod using fastboot from my computer. I'm having a bit of trouble tracking down the right recovery image though.

Ah that one got posted as I was typing... thanks for the upload. I'll try it now.
It worked! Thanks teh roxxorz. Now I'll go ahead and actually get superuser, install CWM, then restore the backup and hope for the best with 4G
Update: I'm done and everything works flawlessly. Including 4G. If anyone has the same question, I can tell you that it's definitely possible to restore to a nandroid backup, provided that the radios are reasonably close to the originals.
