[Q] Multiple ROM's? - Galaxy S I9000 Q&A, Help & Troubleshooting

Is there any way to get dual/multi boot in SGS GT I9000.
Or any way to change ROM with out flashing, Like a live disc. where i install a ROM in external SD and swap it to change to a different ROM. A crazy idea.
Lots of ROM's to tryout & only one phone to test them. LOL
Every day i try out a new ROM, The flashing part is really easy....Restoring part is a pain in the ass.
Any suggestion.

[Q] Can I dual boot my phone?

I've recently got into rooting my Wildfire and used a stable 2.2 Rom which I am happy with, I really want to try out some other Roms though.... I know I could just use Nandroid to back it up and install a new Rom but I'm wondering if it's possible to partition the phone and dual boot separate Roms?
I did notice the partition menu but would rather not mess with it until I've got some instructions.
Cheers guy's
temporary no XD
Sounds promising, I guess it's being worked on?

[Q] Is it possible to dual boot i9000 with different custom Roms

Hi Devs,
Can anyone answer the question, Is it possible to dual boot i9000 with different custom Roms?
it is possible and is under development, but has not been completed yet, as im sure you can understand how difficult it must be.
I don't think I would be game enough to try that..
Good question

Very Possible (i think)
Galaxy S is a kind of mini compact compute,
using the bootloader, using two kernels side by side on the phone.
as logical question , this my logical answer.
i think by this year, smart developers will reach that point instead of focusing on thems ,app and wallpapers.
this is intresting
thanks

That bootloader thing isn't as easy as you might think
And you have to figure out how to partition the phone because two roms mean two /system and, as far as I know, the space is lean as it is now.
It should be possible but I don't want to be the guy who does it (although I would respect that man (or woman) a great deal)
Well multi boots require separate partitions plus a multi boot loader. Quite an ask for a phone. in theory possible, but sounds pretty difficult to me.

whilst its not really dual boot you could use CWM to make backups and restore the different roms if you want to regularly switch? not what you are asking I know but a work around perhaps.
i would be happy for an app that runs a system of the sd card, kinda like how they used to run android on the HD2. Click the app and it would boot android restart and it boots back to winmo coz thats whats on the NAND .
This would good for people that want to test a ROM, mod it, theme it without flashing the orgional ROM. A Virtual machine if you will

hey guy i have think about what you said if dev can develope multi loader like computer that can we have both winphone 7 with android or maemo with bada or meego with ios! that sounds good and i think we can do that cause we have three diffrent storage in galaxy s. that have 2 gig rom that we have used it for android by now and we make it lagfix and change it from rfs to ext. another storage is internal nand that is 8 or 16 gig that we can use for further os like ios. and at last for blue tooth or else we can use external sd storage up to 32 gig i think galaxy s is more up than n900 or hd2 so we can nand and port real os on it!
BootManager - ROM multiboot
Hello, someone knows if this app works on galaxy s i9000?, I have a version of this device sold exclusively here in Brazil it is called I9000B, the only difference for the I9000, is that my tv is digital!
I wud love to hav dual boot - Android n WP7 (like HTC HD2), but having 2 android OS doesnt make any sense!
Actually does so, this way we can enjoy two different roms at the same time, can have the best of two worlds!
No updates? I thought we could just have an entry in the recovery mod which backs up the old kernel, flashes a new kernel, maybe modded to mount the /system and /data filesystems from sdcard images (system.img & data.img), replaces init.rc to avoid problematic mounts, and then boots the other rom. then, to reboot in the original rom, enter recovery and select the default one. I just want to know what are the problems we could find with this method. I can help, if someone is interested in doing this. I'm not a dev, but I can prepare images, edit init.rc, and if you give me the source I may be able to edit the recovery. I really want dual boot on my i9000, to test roms without wipes and backups, to have choice, to have a recovery rom in case something goes wrong with the default one and I'm not at home. For instance, it happened to me, that sometimes I couldn't listen to music when I was on the bus, due to roms' problems. I wish I could boot an emergency rom in cases like that.

[Q] Lots of questions before I flash my device.

So, I have a SGS I9000t and am currently very frustrated with the official firmware 2.2.1, since some apps are having terrible issues. Whats worse is that lots of my programs are having constant crashes. My available ram is always getting capped, and i have to uninstall some programs that add functionality that while unnecessary they're nice to have.
Now I have been thinking, what to do? I hear I could flash my device. Doing so would improve its performance, even update to gingerbread. So now i have some questions. I bought this phone and recklessly installed darky's rom. It worked, but without 3g. Other than that, it was pretty amazing. I kept screwing around with it trying to fix 3g and finally bricked it. Took it in for warranty and got a new one.
I dont want to repeat the same mistakes, so this time i want to be extra careful.
Is there a way to do a complete backup? Like every single piece of data in ALL of my phone's memory backup. In case this flash goes wrong, I can just make it work just as it was before?
Is there a way to try roms before flashing? Like just load a rom on top of another rom without altering the current rom.
I would like to evade roms with 2.2.1 firmware, because of the problems mentioned before, so whats the best, non 2.2.1 rom available? Most stable, just plain best.
Since y phone is a i9000t my modem seems to have some problems when flashing, so here are the details of my phone: Model GT-I9000T // FW Ver 2.2.1 // Kernel 2.6.32.9 [email protected] #1 // Build FROYO.UBJP9
Im sorry if this is a lot of info, i just want to do this right. If I flash my phone its for better funcionality, not to get worse. Thanks for your time, if youve read this far. Hopefully you can help me out.
You are asking to be spoon fed information that is out there already!
1st rule of forum is look before you ask, people will help you if you make the effort, but you have to make the effort first. Sorry if this is harsh, so as a pointer, read the main q&a first as a starter

Ahh yes. Ive read a lot actually. Not the basic stuff though. I may have to sit down and read up.
One quick question though, Im sure its not in the FAQ.
I have been dealing with my phone and I see now that many of the problems im having are created by the apps themselves. Will changing my rom actually help greatly? Is 2.3.3 recomemded?
Sent from my GT-I9000T using XDA App
samsung use rfs file system that decays over time, hence people tend to lagfix to cure this, ie. Convert to ext4, this is done through a kernel tweak, you need to start reading and learning, im sorry but I wont do your homework for you!
Sent from gt i9000 insanity 8.5/fugumod
Your problems are not due to 2.2.1 Its the best non GB rom .
Your first step is factory reset .
Second check Kies for an update .
Third step would be to remove these problem apps .
But i just spotted the problem at some stage you installed a darkys rom
Known killer of phones ..
Total removal is flash stock froyo 2.2 rom with pit and repartition checked .
jje
I flashed darkys rom but traded that phone for a new one. So I have a fresh factory 2.2.1 and its working very well. My biggest problem is the bug with programs resetting/not saving settings because the old data stays after uninstalling. Also the rom runs great, what im looking for is better compatibility on perhaps another rom. But you say its as good as it gets so I may be staying with this rom.
Edit; Also, I must add that Kies cannot update my device, because my service provider has my device locked on that firmware. Now what you suggest is flashing to 2.2, then updating to a stock gingerbread rom through Kies? Should'nt I just flash GB and get it over with?

Yeah, ODIN is your friend.
Well, now that I have a couple of people here, I will ask, which if these two roms would be better to install?
Gingerbread 2.3.3 stock Samsung or
Juwe's Smart Edition http://forum.xda-developers.com/showthread.php?t=964672
I like how juwes sounds, but it says something that bothers me, and that is, that it has no bugs, and that is an extremely ignorant claim, since the gingerbread release will always have bugs, no piece of software is perfect, ever. That said, it could be much better than samsungs, so help me out on this one. Thanks.

If you go around looking for a problem, you are most likely to find one. This applies to more than just phone firmwares. Like you said, no system is truly perfect... With that said, I would recommend you try a custom ROM over any stock one... And Juwe's ROM is a pretty trusted one on this board... so sure, go ahead and try it!
I ended up flashing a new kernel. Speed mod or something. It worked amaizingly well. Sadly I had already bought voodoo plus, and i wont be needing that anymore. Im really pleased with my phone now. Thanks to everyone for your advice.

If you are not curious about what are in new roms and if you do not have any problems with the stock rom. Do not flash.....
I will flash haha. But I backed up all of my data before. In case anything goes wrong. Thanks for the advice though

I'd say that the voodoo plus app still will be quite useful as it works its magic regardless of kernel. You might find yourself on a standard kernel one day, and then you will still be able to enjoy the improvements of voodoo.

This is a known problem, i had it happen to me several times on froyo firmwares. Solution is to go into settings, applications, then clear data and cache of the problem program, then uninstall it, and go into /data and /dbdata/ and find any data the program has left behind and delete it. Reinstall the app from the market, and the problem should be gone. Havent had it crop up in gingerbread yet.

[Q]Dualboot Android

I love so much AOSP Roms for our Galaxy S I9000..I have done a nandroid back-up of Galnet MIUI v4 and Cyanogenmod 7..so if i want one of two roms i have to format system/data/cache/datadata from recovery and then restore the back-up..
My question is if is there a way to manage to do a dualboot between this two (or others) Roms..??
I think if it is possible it will be a great develoment for our Galaxy S..
Maybe i'm sayng a stupid thing but i want to read your opinions about this..
Cheers
i dont think its stupid at all, this would be a great feature! I have seen this in other android devices!
I've always wondered this too.
This was done on my previous device (HTC Hero) but it was a bit of a pain. The second Rom was installed on SDcard which was slow, and was FCing constantly, etc.
Whoever's interested can have a look at the HTC Hero forum section. It was ported by Kendon (he was part of VillainROM back then, don't know now).
Hope some developpers can do this ..
If it was possible on Htc Hero with less memory and less power it could be done also on Galaxy S I9000..
But Htc Hero is Htc and Galaxy S is Samsung so..i don't know..
I'm sure this week in dev I saw a trial program to do just this, running up to 4 roms! Will hunt down link if I can! Brb

Hi there,
Dual booting is kinda possible.
First one is to have very slims roms so you can install both on the nand and select one using a modded recovery.
Second one is to use redbend_ua script that will backup the current running rom, and then install another one and run it. The operation takes between 5 to 10 min depending on the rom and thats the only possibility to switch from 2.2.1 to 2.3 and vice-verca without having to flash bootloaders as redbend can flash bootloaders.
Also using redbend can be tricky as it can dump and write on partition but if it fail at flashing bootloaders you will be bricked.
Bricked phones can still be recovered using j-tag or 301k resitor.
Here is an attempt by z4ziggy:
http://z4ziggy.wordpress.com/2010/09/15/rom-flashing-using-redbend_ua/
The script in this page does not work but it can be improved.
You should check with him and some good dev like supercurio or codeworkx.
Also before applying any scripts, post it here and ask other people to see if it seems correct.
Happy flashing.
quick edit:
Be sure to dump the whole rom and restore the whole image even empty bml as it may have an importance.
We have to ask to developpers..
Not really, try to make a script that dump some bml, then try to restore them is it works then your good to go further.
Finally when you have a working script use tegrak kernel sources to include a "boot selection" as he did.
(on tegrak at phone boot you can enter recovery using the "home" button, change that to run the script so if you wait it boots normally, if you push "home" it dump the current rom and restore another one to boot on it)
Editing again:
If you use 2.2.1 bootloaders only, you can symlink an rom.img at boot and boot on it, it is easier but it is also pretty slow. (see nexus S rom port by supercurio)

Boot up to 5 ROMs Instantly

Is this a must?
really cool app but this thread belongs in the themes & apps section
Playing around with this now, thx for the post. Never would have thought this would have been remotely possible ..therefore I never looked for anything like it via market lol.
cool app, but, how does it work?
is it automating the flashing process?
is it changing the boot.ini to make my phone look for the other os install on the sd card?
am I flashing like mad going in between roms?
I find these questions need to be answered first before I install this.
the way I understand it is
1.main rom i flashed on my phone internal memory+(kernel)
(on SD)
{
rom2+(kernel)
rom3+(kernel)
rom4+(kernel)
rom5+(kernel)
}
and the app works by flashing an update.zip that changes where the phone looks to boot.
Am I correct in my understanding?
EDIT:

Useful answers
1. Will this also work if you have a froyo rom and gb rom that you are switching between?
Yes u can install whatever roms u want to whatever slots gb roms froyo roms whatever makes u happy they're all completely separate it's like having 5 different phones basically
**** remember your radios folks we have mr1 and mr2 some roms need separate radios so if you use the app and swap, you wont have any data untill you flash a new one through hboot.
2. Are you saying that when you flash between roms, the app will auto wipe data, cache and dalvik?
The app creates imgs into the slots when u install a fresh rom to a slot u should check all the check boxes to wipe data cache and system but it doesn't wipe the data cache and system on ur phone just the slots data cache and system the app doesn't touch any of ur data on ur phone just makes it's own in the sdcard
3. Let's say I have Chevy's Froyo rom and his SS GB rom on there. If I flash from GB to froyo, then back to GB. Will I have to restore apps?
No each slot is saved all of it's data stays there nothing is ever wiped again just like having five phones basically all of ur slots are completely separate all of ur data is separate and saved nothing is lost
it aint workin right for me. I tried doing an install from the sdcard and it is telling me i dont have enough space. but i have 1.37 gb free!
This app is kick a**! I know one of the devs that made this app back from my D1 days (he was co-creator of one of the best D1 ROM's IMO) and he is an amazing dev! I was lucky enough to test this app and it is def worth the $$ if you're a person that can't decide on 1 ROM or you just like to try all the latest and greatest ROM's that drop.

So my question is...does it run the ROM from the SD card?
If so...how is the speed/lag once the ROM is booted up?
I like the idea of having different ROMs to test, but I'm wondering how much time you'd be saving if it takes that long to install a ROM initially.
A lot of these Devs have nightlys or almost nightlys....
Very interesting...
looks pretty retarded to me... right up there with rom manager. i cant wait to see how it effs things up for some beginner noobie
not all roms work,you may get FCs during setup... yeah looks pretty amazing.
think ill stick to manually wiping and restoring my nandroids after i get them set up.

That's what has kept me from purchasing it. It's been in the market for a few days now but if the rom runs off the sdcard it could cause issues.

On initial setup do you need to reinstall your current rom?

Yes, it runs from the sdcard. Lag is minimal if you let the kernel settle when you boot one up. On my thunderbolt I don't really notice any lag and i don't even overclock.
