I'm pretty sure the answer is no. Only thing you can do would be to switch between your nandroid backups

I have multirom installed on my nexus 7 and have 4 roms running. Not sure if multirom can be ported to s3.

While I am sure it can be done Orbison really no different then keeping a few nandroid backups of other roms and restoring them. Not the wisest idea but fun at times

Not exactly called multirom. what im talking about is safestrap for the droid 3. yeah backing up and restoring nandroid might be the same but this is alot faster and more convenient. I wish I new how to develop lol

boot manager doesn't work apparently. found a tutorial on how to dual bot stock with cyan mod. it says to install siyahs kernel. would i brick my phone if i experimented with other ones to? and what would the steps be to port safestrap to s3? I know I would have to get the developers permission and stuff if i wanted to attempt doing so. its basically a whole new bootloader I think lol.

Well let me put it this way: It depends if you have a good warranty :silly:

Playing with bootloaders is a very dangerous thing and probably shouldn't be the first Dev project you take on.

that's a good point haha. have you anyone tried dual booting? It says in the tut to post the tutorial on any forum. would it be unfair to do post it on here just to see what people say without trying it myself? lol

I never tried it myself as it's not a feature I need. I enjoy a ROM that works and don't look back once I've settled on one. I will though be entertained by others.

Posting the tutorial here probably isn't the best idea as it could cause some people to brick their phones. Imo, you could look for a Dev who's willing to look at it.

DO NOT INSTALL SIYAH! It is for the international version. You will hard brick and we will point and laugh.

yeah i didn't do it cause i had the feeling not to :p I backed up my stock rom and installed galaxy mod discovering that My imei was corrupted and didn't back my efs. i restored stck and it was back and I had data back. If I go back to galaxy mod and backup my efs how would i be able to restore it back so i have my imei number on galaxy mod or was that not a usual case?

It's unusual but can happen. Replacing your efs folder with your backed up one should fix it.

As another option, there's a thread specificaly for it. Let's your fix your IMEI without a backup (of course, backup is better/easier).
