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.

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
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 .....

If you put spaces in the name of your backup file in ROM Manager you will get a Md5sum error when restoring your backup.
To fix, boot back into your current ROM and using Root Explorer or an equivalent file manager, remove the spaces and try again under recovery. Should work now, unless you truly have a corrupted file....
Also I do not recommend Rom Manager on the SGS2. A lot of people complain about bad backups and problems with flashing or restoring!
There have been problems with some roms and Rom Manager because the CWM recovery that Rom Monager "flashes" is not a real recovery. It is only an update.zip file placed on the internal SD card of the phone. The real CWM is the one that is combined with your kernal.
However, for those flashing CM7 nightlies, it is still a useful tool as it makes downloading and flashing new updates almost a one click and fool proof exercise. Importantly, Rom Manager makes sure that the files (including restoring your backups) are not corrupted or incomplete through the MD5sum check. Not sure if real CWM kernals do the same so I like to use Rom Manager to make sure nothing goes wrong.
For those having difficulty booting into proper recovery from Rom Manager, there is a free app called Quick Reboot which works well.
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.

I did the ExynosAbuse-v1.40 exploit, install Mobile Odin Lite, SiyahKernel v2.6.14, ClockworkMod Recovery, and install CM 10.1.3.
My first root and rom install and everything works great! Battery life went from one day to three and operating quickly.
Do I keep the files on my sd card or can i delete them?
For future installs and upgrades, is CWM recovery my primary means of install?
Thanks guys for your hard work. I really appreciate all you do and plan on donating to the cause.

"on my sd card"? You meant external uSD card or internal memory?
Either way, you can delete them if you won't ever need them again.
From this point on, any flashable zip file will be run using CwMR
Welcome @dave042,
-and congrats on a successful first root/ROM experience.
regarding the "files on the sd card", If we're ignoring the expansion slot, then there are files that apps use on the internal SD, so I wouldn't go deleting them at random. I'm sure that a google search will help you with which folders are needed, and which are not.
All future firmware installs should indeed happen from CWM recovery. Once you're rooted and kernel'd, there isn't any need for mobile ODIN. The options offered in CWM recovery are superior.
As you try new things, I do advise that you do some cleanup inbetween ROMS. Dirty flashes often lead to issues that people blame on the rom or kernel. factory resets only catch a portion of the critters. @mrcook has a few rom wipe scripts specifically for the i777 that have helped multiple people (myself included) out of weird phone issues that were the result of old-rom-junk not playing well with new-rom-junk.
Happy flashing
-Cyril
thanks votinh and Cyril for the quick response.
the SD card i was referring to was the external SD. i don't plan on installing too many roms but will make sure to do a complete wipe prior to any install.
was this process of installing ExynosAbuse-v1.40 exploit, install Mobile Odin Lite, SiyahKernel v2.6.14, ClockworkMod Recovery, to get me to root? and once to root, to install a rom?
another question, kernal and rom updates, are they independent of each other? can i update one without the other?
i understand roms are numerous and customized, what about the kernal? does changing the kernal make any significant changes to the operating system?
Gneerally on this device ROMS will come packaged with their own kernel. The kernel will be flashed when the rom is flashed. I do believe however that most install AJK after they flash their roms.
You can delete everything off your sd card. I do keep a known good rom as well as a copy of Siyah 4.3.3 kernel on my card at all times. You never know when something is going to mess with your phone, and you may have to re install a rom in order to make you phone function again. I would hate to be somewhere, my phone start a boot loop, and I am stuck without a phone. The Siyah 4.3.3 kernel comes in handy for me. Some roms will give you an error 7 when flashing. Rather than messing with editing the build prop I just flash Siyah, and try my rom again.
If you go flashing kernels make sure you have the proper kernel for your ROM.

ExynosAbuse-v1.40 exploit <-- tool to establish root-access to the device (framaroot is another useful, easy rooting tool for the i777)
Mobile Odin Lite <-- tool that uses root-access to install...
SiyahKernel vX.X.X <-- a custom kernel (one of many) installed primarily to provide cwm recovery, but are also commonly used to:
-provide additional functionality to the existing ROM
-backup your ROM install
-install a different ROM
-install a different kernel
-flash cleanup scripts
-and many many other things
As Butchr stated, the ROMs are usually packaged with their own kernels, so the kernel used above only remains in place until another ROM is flashed, which will overwrite the existing recovery with one specifically designed for the ROM flashed.
