Hello, I'm really interested if it's possible to dual boot our device using a stable froyo ROM, and a developement gingerbread ROM.
Do any of you have some information about dual booting?
Thanks
Dual booting is very easy using nand backups. After installing a custom recovery, you will have the option to backup your system. This will do a full backup of the internal storage on your phone. Then you can install a different ROM (gingerbread) and use that. When you want to switch back to the stable froyo, just boot into the recovery, make a backup of your gingerbread system, then choose to restore your froyo backup.
I run at least four different ROMs on my phone using this method. (hint: you can rename the folders under /sdcard/nandroid to be more descriptive.)

That's not dual booting. Its a PC equivalent of reinstalling every OS everytime you need a feature from the OS.
Try running virtual machines. I had a hard luck booting Windows 95 (crashed frequently on Qemu)
I have a theory. Nandroid backup of both ROMS, delete data.img files, restore backup of ROM you'd like to boot into. You should then be running a different ROM but with the same data files.
JUST A HUNCH
u can !
actually u can run it with windows .....

Hey all, I have rooted and flashed my fist android phone thanks to this forum. And also soft bricked it during a voodoo 1click lag fix install and saved in Odin and re-flashed again lol.
I am looking for a kernel (like I know exactly what it is) that will increase the performance of my device. I currently am running Axura Final and have CMW and Titanium Backup installed.
What kernel would be best for my current set-up and p[referably one that I did not have to use Odin to start the process all over. Looking for a sort of download to SD and reboot in recovery and install type thing!
Thanks in Advance!

Here is a thread with all of Eugen's kernels, but you need to register beforehand. Also, stock EB kernel is good, it's found there...
I'm using "B_Stock_1120_100 Kernel" with all tweaks enabled and JFS on all partitions.. About the best stable experience you can get on any JK2 or JK6 based Froyo build IMHO..
Going forward, you may want to read up in here or post in General Q&A to avoid a flame fest, as this is not exactly development thread worthy...
Thanks, I appreciate the replies. Just read the forum rules, I guess this is in the wrong section. WEll since I have your attention, the B Stock kernel you linked me to, is it as simple as installing on sd card then reboot to recovery and load from zip?
Yes, if you are booting into and flashing from clockwork recovery..
You can put the clockwork recover update.zip in the root of you INTERNAL SD card and boot into from the stock 2E recovery. Alternatively, you can install Rom Manager and have it propagate the flash commands within android.
Perfect... Also, when I use titanium Backup, Will it save all of my current apps as well? Then I just restore from Titanium Backup again right?
To answer your question simply, yes, TB will backup and restore the APK an Data associated with a 3rd party application. Take caution when restoring anything other than 3rd party apps or apps from the market as you can easily make a mess if restoring from different Roms or Android builds all together.
You can do so via the batch menu, selecting to restore/backup all apps with data. If you are in fact a "N00b", I'd stay away from restoring system data and apps until you have a better feel with what can safely be altered. Also, if you don't recognize something in the list, don't restore it.
Good luck
one more thing, If after titanium Backup I decide to go to R13, MUST i re-flash to stock and re-root and then flash R13, or can i just move R13 files to sd and load via CW
I have been switching from Rom to Rom and using CWM to install and make backups of each Rom on my SDcard, so I have a good reference install of each to return to if and when needed.
The one thing I have been scratching my head over is why does certain Roms ie.. CM7 need a different CWM than say the Superclean or GeeWiz for installs or to make backups. Is there a single CWM that can be used for all, I just find it annoying to have to Odin back to a certain CWM to re-flash a backup copy of a Rom off my SDcard.
So, I used ODIN to flash CWM and got to the recovery menu. The first thing I notice is that it can't access certain stuff (system partition, for one), but I still kept going.
The only thing I tried was to do a backup with CWM, and it start as it does a boot and recovery .img backup, but once it tries to do a system backup it gets to the same problem about not being able to mount it. Is this normal or am I doing something bad?
Because of this, I stopped my effort of installing a new ROM because, if I don't have a safe and full backup of my Stock ROM, I don't want to risk it using another one.
Its bcuz different file systems: cwm only supports ext2/3/4 and stock is rfs

Hey Everyone. Sorry if I posted in the wrong spot, but I've watched the "noob" video, and I couldn't find anything about my phone on here. So, I've become interested in custom roms, and I'm thinking about learning how to make some. I currently own a Galaxy Proclaim, and I havent been able to create a nandroid backup. I've successfully set up the adb on my Lubuntu Netbook, and I ran adb backup, and apparently that only works for ICS. So, that leaves me with a few questions. How do I make a nandroid backup of gingerbread? What does ROM Manager, from googleplay, back up? And Is there a way I could make a backup manually? I know how to backup the files on my system, but how would I backup the bootloader and everything else? Sorry about all the questions, I'm just curious and determined to make a custom ICS rom, or compile a ROM from source, but I'm afraid to try anything because I don't want to brick my phone.
Buddy do it via cwm.download compatible cwm for ur cell to sd card to root and go stock recovery m0d install zip from sd card and select cwm then select backup restore and in that option just select backup and wait until its done.u need root for flashing cwm in recovery.

Clockwork Manager doesn't support my phone. The phones model number is SCH-S720C. I've tried other backup apps and they back up my apps/media just fine, but I need a full nandroid backup in case I mess up the boot loader or flash the wrong .pit file. I'm not taking any huge risks this time since I bricked my last one. Is there anyway I could make a backup manually? I currently run Lubuntu 12.10, and I've compiled adb and it works right on my computer.

My phone wont boot into android because of a bad setting I made in pimp my rom, it only boots into recovery now. So what I need to do is sort files modified by a certain date and time (last night) and restore them with originals hoepfully to get my phone to boot back up.
So how do I navigate and search my root directory through 4ext recovery or bootloader, because those are my only options?
Is there a way to mount these directories and browse them through windows as if it were an actual folder so I can use windows 7's build in search features as well? I have android commander installed and can use that if need be.
Just not sure how to exactly approach this without installing my rom back over again.

Man you should have made a backup thru recovery before changing any settings using Pimp My ROM as its clearly mentioned in their thread. I don't think that you can mount ext4 in windows. So, in my opinion, your only option is to re-flash your rom.

I know! First thing out of my mouth last night.. "Why didnt I make a nandroid"
I think thats not possible, your only chance to get your data is flashing the rom again without wipe...

I'll just make a nandroid now, and manually restore directories after flashing my rom again, see if I can get my apps back without having to redo them all.
When you reflash the rom without wipe, your data (apps...) will usually not be gone. But better do a backup before!

Yeah you can try that. Good Luck!
Ok so I did the nandroid, then reformatted everything, reflashed my rom, then used nandroid manager to restore all my apps and data, pretty much back to normal now
