Multiple Rom Question - Samsung Galaxy Nexus

I've rooted before but this will be my first time using ROMs. I've already flashed to one ROM but curious to try others. Do I have to wipe and flash to another ROM, etc? Or is there a way to have multiple ROMs?

Try bootmanager it let's you boot multiple roms.

It says ICS is having issues with it :-(

Only one way to find out! It is the only one I know of dude.

You can always make a backup of your current rom ans restore it after trying another

Go into ROM Manager and make a nand backup of your Rom before flashing. Depending on which ROM you are moving to it is a good idea to then copy the rommanager/backup folder off to your PC before wiping then you can copy it back if needed.

I have been running this rom for a couple of days now. Its fast quick and very well designed. But I have been experiences a couple of issues. 1 wifi disconnects even when im next to my wireless router. 2 I get alot of droped calls for some reason while im on the phone an app will launch and drop my call. 3 Slingplayer works but when I change channels no picture comes up only the sound. I have used other roms and never had this issues can I get some help anyone.

I have been running this since it came out wiped and flashed it multiple times over the course of messing with my phone and never had any of the above issues.
The first thing I would try is to wipe everything with calk's format all zip and reflash the ROM.
Do you have the link for zip file.

Flash from recovery. I usually wipe cache/dalvik/data/SD EXT (if your sd card is partitioned) and then flash the zip. If you are using Amon Ra, just flash that zip like any other ROM/Kernel, etc. You can flash it with older versions of clockwork as well, but not the current version. If you're running a newer clockwork, and it gives you an error when you try to flash it, just manually wipe cache/dalvik/data/boot/system then try flashing the ROM again.
Also, if you are using Titanium to restore your apps, make sure you don't restore any system data and when you restore your apps, restore app only and not app + data. If your backups are from a Froyo ROM, the safest thing to do is redownload them and make new back ups. I think you can change the name of your Froyo backups folder on the SD card so that you can keep them and use that to restore if you flash any new Froyo ROMs. Most people don't have issues restoring apps btw the two, but if you're having issues, better IMO to be safer. Hope that makes sense.

You could have used the same thread buddy
Either way is fine with any rom.
You can mske a backup of whatever you are using, flash a new rom and then revert to the backup if you want.
Or you can just start all over and flash another rom. You need to full wipe always.

I've never found any bugs with a nandroid backup and have used it on multiple devices.
Sometimes if you restore app data using something like titanium you can get probs depending on the rom but nandroid backups are fine.
last time i used nandroid on sabsa prime 3.0 i got bootloop... just wanted to warn prospect since lots of people got those problems even with nandroid.

So technically the only time one should perform a nandroid backup is when he/she wants to switch back to the stock fimware otherwise "install zip from sdcard" is better

No.
You can make a nandroid backup anytime you want and restore it. It is advisable to make backups before flashing anything to the phone. Mods, scripts, etc. Just in case something goes wrong. That way yoy can go back right where you left it.
The other member, seems to have been talking about that particular rom, however strange it may sound. And there is always the possibility that in that case, either the member did something wrong or it was an isolated case.

A few questions about flashing stock ROM to activate on Sprint

First, Merry Christmas!
So here is my situation. I planned to give my sister my old Samsung Epic for Christmas. I put CM10 on it, threw in a new battery and watched her unwrap it. She was happy. Unfortunately, I discovered that you cannot activate a CM10 modded phone on Sprint, so I need to flash a stock ROM. I have never done this before, and it's been a while since I messed with Android and since she leaves the state in a few days, I need to do this quickly. I hope you can bear with my possibly silly questions so I can get this done ASAP!
1) I have seen the ROM listed here http://forum.xda-developers.com/showthread.php?p=12755712 recommended. I plan to use this. Any issues?
2) I understand this will revert the file system back to RFS. Will I be able to restore my CM10 nandroid, or will I need to re-run the CM10 flash from scratch in order to reformat?
3) Are any of my assumptions incorrect?
Normally I would research the hell out of this rather than ask for help, but under the circumstances, I am in a bit of bind time-wise.
Thanks!
1. EC05 too old. Get FC09 tar here: http://forum.xda-developers.com/showthread.php?t=1592994
2. Yes, you have to flash CM10 to convert to MTD in order to restore nandroids of the format. Don't forget to wipe /system if you ever wanna flash a CM10 package, or you'll have to pull the battery...
3. IDK, I'm in China and have no knowledge of carriers
Sent from HTC Incredible S @ Sense 4.1
Just flash a stock based mtd ROM like the peoples ROM mtd. Activate and then flash back or restore back to cyanogen. I've heard that some people have issues flashing back to another ROM from cm10 because of the partition resizing. But I've jumped back to cm9 which should have been an issue, but was not. Give it a try after a backup. Worst case you have to Odin back to stock like originally planned.

As suggested you can just flash a Touchwiz MTD ROM like The People's ROM. Activate then restore your CM10 nandroid or wipe data in CWM and flash back to CM10 after.

Or just stay on TPR and enjoy the succulent battery life
I've done the multi boot method where you boot off the sd card. It works great and is a lot faster than I thought it would be. You keep your cm10 system exactly as it is. You also can leave the OS files on your sd card and install the zip from recovery any time you need to update the prl or adjust radio settings.

[Q] looking to switch roms? currently running jellybomb

Im new all this rooting and rom stuff and yesterday morning i successfully rooted and inststalled the jellybomb 14.0.0 jelly bean rom thanks to qbking77's on point videos. so the question is... how can i switch which rom im running? i like the jellybeen roms and im looking to explore more to see which better suits my needs. ive heard of doing clean/dirtry instals or something of the sort but i want the best and safest way possible so i dont run into any bricking trouble. please help?
Ok, read up on how to flash a recovery
Download the rom of your choice and place it.on your sdcard. Once you do that you can install roms by booting into recovery and finding the zip for the rom you want to flash and selecting it through the "install zip from sdcard" option
Now a clean install is whenyou wipe all partitions, aka blocks of your phones memory, (details farther down) and then install the rom zip. This method minimizes the chances for problems to occur after installing
A clean flash involves:
Formatting system
Formatting / Clearing data (also known as a factory reset)
Wiping cache
Wiping / Clearing dalvik cache
Now a dirty flash is when you just flash the new rom zip over whatever you're currently rumning, without clearing anything. This method is only recommended when flashing an updated version of the same rom, and even then, the nature of some updates can require you to do a clean flash.
One more thing, DO NOT flash any roms, mods, or zips for the international version. That usa surefire way to brick your debice because the partitions are completely different.

Backup via CWM (RECOVERY) is mainly for restoring the same rom or going back to the rom you were running if experimenting, Now, can use apps such as Titanium backup to save all the other settings, apps and things. Once you flash your new rom, download it, open program and can restore your stuff that way. Personally, I'll wipe, start from scratch, sometimes i'll download an app i never use, and it just allows me to clear out the useless ones.. Happy flashing!

Yes as said above, a backup through recovery (also called a "nandroid" ) stores an EXACT image of the current state of your device. Meaning all data, all system files, all apps, radios, etc. Backing up through an app, like Titanium Backup, only backs up certain things like apps and app data
Basically, if you're trying any experimental stuff that may break your system (for example, flashing a new modem or testing to see if a certain kernel works), then a nandroid is the way to go because you can restore to an exact image of a state when everything was working
Yea I did that the 1st time and couldnt recover anything. Is there a certain way I should recover or maybe I did something wrong? Im not sure. Sorry if im sounding stupid but I cant return my phone if I screw it up so im tryin to be as safe as possible. Hopefully thats understandable

No no, its recovery
The recovery is basically something that allows you to install zips, it doesnt actually have much to do with recovering anything lol
But first do what was suggested right above me to check to see if you have a recovery installed
To get a more detailed description of what a recovery is and what it does, you can get over to xda-university and read through the "as user" section on recoveries
Think cwm has saved a few phones on here. Me I don't use a pc. Easy just with phone. If he's deleted his folder should he recoveR then it would bring that folder bk?

need help getting a rom

Hi all i have a galaxy s3 t-999 and just rooted with and now i want to install beanstalk rom for it
but i am having trouble knowing what to do?
let say everything does not go well and i want to recovery my original rom how would i do this and how do i download the beanstalk rom into it
please help thank you
You should read more before flashing anything. If you have to ask how to flash a ROM, then you probably shouldn't be doing it.
A good place to start reading would be in the android development section.

if you have cwm recovery, simply make a NAND backup. So if anything goes wrong, just restore back to previous ROM with everything intact.
Only flash ROMs for T-Mobile version. i9300 is different and will brick your phone.
To flash a new rom, wipe data, cache, then flash the ROM.zip from SD card.

Make sure you do some learning cause even just having a backup is not always a save. I have had backups fail. So I recomend having a second rom on your sd so that you can at least get a rom back on the phone. I almost bricked my phone and the sec rom I had on the phone saved me.
