I've had my sensation for a few weeks now. Still on stock room 2.3.3, no root.
I want to do a full backup and restore of the ROM, like a nandroid backup, before experimenting with other ROMs.
If I boot into the recovery/backup mode and do a backup, is that the same as a nandroid? Will it backup the entire ROM as is?
If so... if I then S-OFF, experiment with other ROMs, and then recover from that backup, would my phone still be S-OFF or would it revert back to S-ON?
I know the preferred method is to root and then do ClockWork Recovery, but I'm wondering if it's possible to do a full ROM backup before rooting.
Thanks.

A nandroid backup is done using ClockworkMod rcovery, which means you need to S-Off and install CWM before you backup. This will be a full backup of the phone at that point and would allow you to restore to that same point.
So what is the difference between the nandroid/ClockWork backup and the backup done after holding the volume down and starting the phone?
The latter only backs up contacts/settings/etc?

When you hold the Volume down and Power button, it takes you to the HBoot screen. If you select Recovery, that takes you to the Recovery mode. If you have ClockworkMod installed, you will get a recovery menu which has the backup and restore options ands this is a nandroid backup. I have never seen the standard HTC recovery screen, so I don't know if there is a backup/restore option or not. Every thing I have read about nandroid backups has been in reference to CWM and that's the way I have always done it on my 3 HTC devices.
Someone please correct me if I'm wrong. I'm always eager to learn.

My phone is rooted, backedup with clockwork and I even used sprite backup to backup the phone just in case. I plan on flashing my phone for the first time with the Epic Experience rom since it seems to be the most popular.
I'm pretty happy with my phone's current state except the battery life once in a while. So after flashing with a custom rom how do I revert back and restore my phone to the "EXACT" way it is now?
Make a nandroid backup in clockwork, then you can go back whenever you like.

Restore nandroid backup and flash stock kernel. You will most likely have to flash a non stock kernel for a custom rom, and even if you dont HAVE to, you will probably want to.
So to go back to stock, flash back to a stock kernel, and then restore the nandroid backup.
are the steps to creating nandroid backup the same on the epic as others? I can't locate a tutorial for the epic specific

yeah its pretty self explanatory, boot into clockworkmod > backup. or you can choose backup current rom an rom manager if you use it. thats your nandroid system backup
that's just confusing. So basically, a nandroid backup is the backup creating using clockwork? lol if so, that was the first thing I did after I installed clockwork.
This is a noob question, but I have a bit of experience under my belt just so you don't have to worry too much about using "confusing" terminology.
I have rooted/ROMed many devices in the past and have heard guides talking about doing a Nandroid backup. My question is how exactly does it work? Say for example: I am on the stock ROM (rooted of course) and I do a Nandroid backup while on stock. If go to say Cyanogen and I don't like it can I just restore from my nandroid backup like I would flash any other ROM to go back to stock. And if that will get me back to stock does it also preserve all of the user data that was in that ROM when it was backed up?
Any other information about about nandroid backups would be appreciated. Thanks in advance!
From my understanding, the backup backs up all the stuff on your phone EXCEPT for what's on the SD card.
The idea is that you do a back up. Then install a new rom that you want to try out. BUt you don't like it, so you just restore the backup and woolah! your old phone is back along with all your settings, data, etc.
I'm not sure why it's called a nandroid backup, but from what I gather, you can do it with clockworkmod, just boot into recovery. And use the backup and restore option.
That was my understanding as well. I just wasn't sure on the situation with the user data (or the backup in general really). So all it takes is a nandrid backup to revert back to (rooted) stock?
A Android backup takes all the files on your device and saves them as a data.img,system.I mg,cache.I mg,user data,and recovery.img. It is also restorable through fastboot. It can also get you out of a tough spot. Say you are messing with a new theme and it causes your device not to boot up or causes unwanted problems. You can restore a backup to a time when your device was working correctly.

this is true unless you do a nandroid+android_secure backup. this also backs up your external app data

Yes you're correct. You can restore but just remember some app might have ext data in sdcard. If you don't delete it, when you restore you'll get the same as before

So if you want to restore say just your data can you just delete the images you do not wish to restore from the backup folder and it will just keep the ones you have? Or won't it work at all if you start deleting images?

i wouldnt tamper with a nandroid backup, but if you have clockwordmod recovery, that is possible. clockwordmod recovery gives you the option to restore one of those images (but only one at a time).
does a nandroid backup include your kernel?

It does! It's a compelete "snapshot" of your phone with all apps/settings etc.
Does it also backup the stuff which has been stored on the external ext2-Partition, which is mounted to enlarge the space for apps?
Same with restore of this nandroid-backup. Will it also place the backup again to the same space?
As I know there's a (symbolic) link put into /data which might get problems.

If you install another ROM with different kernel and then you want to go back to nandroid backup, does it work ?
Nandroid backups
I was wondering if the framework is saved as well. I recently updated to the ICS firmware and am wondering if I restore with a backup from the old GB firmware will that be restored as well or will it still stay on the ICS? From my understanding ICS firmware will run previous versions
will nandroid backup (made from cwm) un-brick your phone if say, you installed a custom rom via cwm and it bricked it?

Yes,It restores all data and apps nandroid backup is a mirror copy of your phone.after restoring you will get your previous stock ROM.

im not sure, i think nandroid backup will unbrick your phone as long as you can boot to recovery. atleast when i installed a roms pach it didnt fully boot, got stuck at bootanimation, no loop, just froze, then i got it back with nandroid backup

Is there a way to convert a nandroid backup into a flashable zip file? I would like to have the possibility of returning to my rooted rom if ever I decide in the mean time to go back to stock rom and don't like it.
The question has been asked a few times but has never, to my knowledge, received a clear answer.

A nandroid back up takes a snap shot of your entire OS. All of the /system files, all of the /data files. All the apps in their current state. I mean EVERYTHING is store in the nandroid back up. When you preform that there is a "backup/restore" option in the Clockwork ROM recovery image. You would just select "restore" then select the back up you want to store. I will advise you not to change the name of the file as the MD5SUMs will not match and it will not be able to load it. It's a flash-able .zip my nature. but it will verify it's own MD5SUM prior to flashing it.
which brings me to this point.
but to restore you nandroid you need to be a) rooted b)have clockwork installed.
Yup, you can do it, but you need a few things:
1) system.img and boot.img to flash
2) you'll also need a non-stock recovery, so if you return to stock, just go back to a rooted stock system, and keep the non-stock/cwm recovery so that you can apply the zip. This begs neidlinger's point above about just restoring your backup via recovery.
3) if you want to really cross your eyes and dot your tees, then you should also get the EBT partition from the stock firmware so that you can update the bootloader. Most people are fine using what ever old bootloader they had when they rooted, but I think it can cause bootloops with certain combinations.
So yes it can be done, but it's more an exercise in android-fu. You'll have to search around and take apart a few zips to figure it out.
what about this (just to see if I understand the approach): I make a cwm recovery of my present non-stock rom and I somehow manage to go back to a stock rom. If I miss my custom rom, I root , install cwm recovery and restore the backup stored on my external sd card...How is that?

That is correct
You are on a custom OS, you make a nandroid backup Via CRW (ClockWork Recovery) (it will store to the SDcard)
you go back to OE not rooted OS with stock recovery.
you don't like it, it's slow or ugly, what ever.
you re-root. Reinstall CWR
you wipe the device
select "backup/restore"
Then restore
and it will restore the Nandroid completely.
you boot the device to the exact point in which you left it.
Just a little question.
if I do a nandroid with my phone (I'm on s-off) and want to return to this backup again..
can I only restore this nandroid and everything will work fine? without flashing boot.img?
example
sense backup -> go to cm 10.1 -> want to go back to sense -> restore -> done?
not sure what your last sentence means--
But, a nandroid is a full image backup of phone, everything will be restored
EDIT: Well at least everything you check in recovery, which is usually System/Data/Boot
I don't check Recovery or Cache. I am on TWRP 2.4.2.0

hm..
if i come from cm 10.1 and have an older nandroid from stock sense,
if I restore this nandroid, do I have to flash the kernel / boot.img again? or does twrp restore the kernel too when s-off?

Yes.
Your nandroid backup contains a boot image and it gets restored when you're s-off or on a low hboot.

that is what I said--it is complete back up--i restore sense and cm roms over whatever rom is on phone
you just can't restore a rom backed up with cwm thru twrp recovery or vice versa

Is there a necessity to install a custom recovery when I'm running on stock rom? (never changing to custom)
If I factory reset my phone and try to restore everything, only titanium backup is needed right? the system apps are the same so titanium backup would restore them. In this case is a custom recovery necessary?
I'm on android 4.4 and rooted but bootloader is locked. I understand the differences of titanium backup and custom recovery but I wanna know if custom recovery is needed on devices with stock rom+titanium backup

If you are rooted then yes its always a good idea to have custom recovery so you can make a nandroid backup of your stock setup, then if later you have issues that you can't get straight you can restore the nandroid and be back to normal, nandroid backups are backups of your entire device, titanium backup only backs up user data(apps you've installed, app data, contacts, pics, videos, music and things like that).
Titanium backup does not back up your boot, modem, system or recovery partitions and those are the important parts, the stuff titanium backup only saves non essential stuff.
If you don't install custom recovery and you have issues then your only option would be factory reset or reflashing stock firmware, these would wipe any data that you want to keep.
