[Q] Switch ROM and back

I'm currently running SR4 plus a few mods and I like it. What I want to do is try out a couple other ROMs but eventually come back to the setup I have now.
Can I make a Nandroid backup of my current setup, wipe all and flash a new ROM, then when I'm done just wipe all again and do a Nandroid restore and be back where I was before flashing the other ROM?
Sorry if a noob question, just like to tinker around with my Incredible

Yep your backup takes you right back where you were when you made it.

Thanks for the reply, just wanted to make sure to be safe first before thinking it works one way when it really works a different way.

No problem!

Yup, I do that all the time when I get in the mood and MUST flash a new ROM. Works like, well, clockwork!

help?!?!

i updated my phone from gingerbread to ice cream sandwich. i did a nandroid backup for the gingerbread. if i decided to go back to gingerbread, i just gotta go into recovery and do a restore? or do i gotta reset wipe factory again and wipe data,cache dalvik?

I flash dark side super wipe before restoring

Before flashing anything even if it's nandroid, it is always best to wipe it clean.

And flash proper radio before restoring, if necessary

The recovery restore doesn't reflash my old radio and kernal? Cuz I'm not even sure what radio it had. So I pretty much need to do all the steps again like I'm flashing a new but use the the restore in place of flashing new rom.

The recovery restores everything (including kernel) but not the radio. I have switched back and forth between ics and gb a few times without ever wiping before a restore and never had a problem. I would argue its not necessary but certainly doesn't hurt.

Restoring back to nandroid.

I'm on cyanogenmod 10 beta 3 and wanted to go back to AOKP Milestone 6 but I'm having problems with superuser (and therefore cant use mobile odin) so I was wondering if I could just restore my nandroid back to EL26 via the JB recovery mode and then flash the aokp ROM through that recovery like normal? Or would that not work/brick my phone?

Bump, really need some input on this. Any help is appreciated. thanks.

Safe bet as I had the same issue: use sfhub one click to go back to el29 w root, then one click root to el26 cwm access and then you're good to go. Just make sure whatever road u take it leads you to el26 cwm by chris41g.

I don't really have a PC at my disposal at the moment though is my biggest problem :/ which is why I was asking if restoring back to my nandroid back up via JB recovery would be safe?

Hey, quick question.I'm just trying to do some reading about safety and such, and came across your post. Wouldn't it be safe to JUST Odin EL26 CWM alone? Without going back to EL29 first? Is that necessary? Again, not being a smartass and trying to call you out, I'm just really trying to get a hold on what is safe, or not, and procedures.

Well the main issue is it seems he lost root access....just saying its safest to start fresh. Only takes 10 extra minutes. If he had root he would've been able to just mobile Odin el26 like he stated, but its not an option.

Exactly. That's the problem I'm having, which is why I'm asking if (since i dont have a pc to use) It would be smart and safe to just restore my nandroid (which is el26 with root and cwm) from the JB recovery (cwm6) and then just flash my original ROM through el26 cwm.
Anyone think this is safe?

It sounds safe, both are quoted as being safe recoveries. I even restored a nand from a broken phone onto my replacement one yesterday so I'm sure what you're doing is far less risky. Its the wiping in non-safe recoveries that caused bricks, you should be OK as long as you don't do something stupid like pull the battery during the restore.

Someone else told me that even while restoring a nandroid backup, it still wipes data, so if you're on an unsafe kernel, it still can brick. Just so everyone knows, I was on a safe kernel when I bricked mine. Apparently there was a mis-merge that happened that caused the safe kernel to be unsafe for a few days. I was very unlucky, but its one of the risks we all take when doing this. I'm planning on odin-ing el26 kernel whenever I need recovery from here on out!

Thank you both for the replies. I guess I'll go ahead and try the nandroid restore.
Wish me luck haha. Hopefully this recovery is as stable as people have been saying lately.

Just thought of something: if you lost root, how do you still have a custom recovery? You may want to wait til ur near a PC to do el26 flash!

No idea but I can boot into CWM just fine, its just superuser won't give me root access. I even tried to do the su binary update and nothing.
I'm not flashing El26, I'm just restoring to my nandroid backup which is el26.

I deleted it because it was a stupid question that I should have known the answer to. It was when you recover a nandroid does the recovery and kernel from when you made the android come with it.
My problem was I am and was on king kang and decided to flash a modem. I didn't realize the jb modems were only for tw roms so when I had no data I though I needed to update prl and profile. I flashed a stock rooted rom from repository, it was rooted but didn't mention had no recovery. Odin kept falling when trying to put a new recovery on. And after 5 hours of fail I finally succeed with a one click from repository. After flashing a modem (fi27) I think. I just wanted to make sure I want going to be stuck with no recovery again because that really sucked. I didn't mention this in the original question but all is well now and I'm back on king kang

I'm on it right now, however, I made some changes and stuff in between the time of the backup and now, so I wanted to just reflash the stock ROM rather than lose all the changes.

Also, is this the stock kernel with absolutely no issues as stable as the one that comes from T-Mobile/Samsung?

Just checking, you know titanium backup can save all your apps and data? Flashing a kernel, then flashing stock back over it isn't exactly a fresh start and may leave you with the odd strange issue. Or not.
Still I'd recommend backing up your stuff and wiping everything, especially the system partition and doing a clean install.
That's what I would do anyway. Just my opinion tho.
