Dual Boot - Epic 4G General

This should really start being looked into by the devs. It would be AMAZING to have it on the Epic4G. Easier said than done. But we got some great devs and I think they can pull it off!!. Please devs. We need this!

What do you mean by dual boot?
http://epiccm.blogspot.com/2012/01/boot-el30-stock-from-sdcard.html
The temporary EL30 boot from sdcard is a method of "dual boot" which has been useful for people to update PRL and calibrate sensors. This old version is problematic in that 3G and 4G data is broken. We know how to fix it, but it would take a few hours of work and there hasn't been demand for it.
Any type of dual boot would boot from the sdcard. The slow sdcard. Not a great user experience.

LOL...I got a quad boot on my phone. If I boot right into CWM I have nandroids of 4 ROMs to choose from to restore. Takes less than 10 minutes to restore one and then there is no issue of running from a slow sd card since we don't have enough internal memory to make real dual boot work.

Haha no Dual booting is when you turn on your phone and have the chance to boot into either windows or android. like windows has.

Is it possible that other phone's ROMs are much smaller than ours? It can be done but would be a tight squeeze on MTD but next to impossible on BML.

Nook color has this. Although I never compared the specs. One boots off SD card, thither off internal memory. Speed off SD is same as internal. But I don't think the epic could handle this as a full time option. Just my opinion. My NC dual boots cm7 and cm9.

Where'd all that space come from? I thought we only had like 300 megs in both RAM and ROM?
Also my friends tp2 and hd2 dual booted very easily into android (infact I think the hd2 is the most developed for android phone after the g1 and nexus 1, and its not even native lololol) and ran extremely smooth (on the hd2...on the tp2 it was like a hero with a keyboard lol. Random sluggishness.)
But nah if the hd2 can handle it I know damn well our phones can handle it. The problem is, everything we can dual boot is closed source so that's why windows phones can dual boot android but not vice-versa (I mean, you could do it yourself but just can't distribute it).
Meego seems like a great choice for a dual boot though since its open source and amazing...

Whats funny is the HTC HD2 still runs ICS or can dual boot etc... and its 3 years old

I have had my head spun by this topic myself -- I've been doing a lot of searches and reading just about every result but I can't seem to find good general info on the subject. I've seen some loosely compiled info on dual booting CM9/CM7, and I've seen some info on the EL30 from sdcard mentioned before, but I had hoped to boot CM9/CleanGB as CleanGB is what I'm running stable and comfortable with now. I'd just like to be able to have stable and comfortable as a fallback for playing with ICS. I know running off the sd is supposed to be quite slow, I don't really know what to expect as to HOW slow, but the way I figured slow was an acceptable compromise for a stable fallback.
My bottom line has been that a lot of kernels seem to support this, yet it feels like there's very little info on doing it, and that just confuses me a skosh. Is CM9/CleanGB even possible due to kernel requirements?

I used to do this on my HTC TouchPro2. It was nice having android on it. The only problem was battery died too quick. But it was a pretty easy thing to do.

Actually, its in the process of being done on the EVO, Its not final if it will work or start, but it was able to boot. Maybe at the End of the Summer, it may be available for the Evo, and it might get ported to the epic, but the chances are highly unlikely.

One of my favorite features of the HTC phones was the ability to dual-boot android or WinMO. The Touch Pro was awesome with this. Unfortunately HTC doesn't want to make a decent phone with a keyboard anymore, and nobody else likes WinMO.

None. No other device uses the same hardware as ours and writing drivers for an entire OS is an unbelievable undertaking we don't have the devs for.

They don't have a dev community so not really. So far there has been one successful "jailbreak" that ruins their ability to update forever. Not much of a future there.

That's what convinced me to come to Android. I had a Windows Mobile 6 phone, and after dual booting with Android for about a month, I realized I liked it a lot better and decided that my next phone would be an Android one. And that was a big deal for me, because I was developing apps for my Windows phone but had never made an Android app before.

The OS has nothing to do w/ whether you can dual boot or not. But more depends on the hardware and and what software and/or drivers the community has put together.

Dualbooting

Can you dualboot miui and cm7?
For what reason would you want to do that?
I'm guessing if you know how to dual-boot then try it make sure you have a kernel that's compatible with both.. otherwise no.
Sent From My "epic" SPH-D700 via XDA Premium
Because I like them both and can't decide which I want as my daily.
With the new partition map and both roms under 118 mb I don't see why we can't have 2 different roms on the internal memory.
I am trying to find a computer science summer school so I can do this myself but summer is far away so I was wondering if any of our amazing devs could do that quicker than me

Possible the how to dual boot in android development .....
I think this method still works very lenghty so read up :
http://forum.xda-developers.com/showthread.php?t=
Sent From My "epic" SPH-D700 via XDA Premium
But that requires me to boot from the sd card which is really slow.
I think this is going to be my first real project.
It doesn't seem complicated.
I tried at other projects and failed so I'm going to give this a shot and if it works I'll post it in the development section.
Yes, one would need to boot from the sd card because there is no current way to share the system and data space. Your phone would not be able to seperate one framework-res from the other...you get the idea. You can't put pot roast and spaghetti in the same pot and try to eat only pot roast.
Sent from my SPH-D700 using XDA App
But if you make 2 system folders and 2 data folders and interrupt he boot path to let you choose which ones to use it might be possible. Take all that I am saying with a grain of salt but our device has done some pretty amazing things the past year and a half so let's let it live up to it's name and try every single way to make it better. I am going to start trying after I get my spring break because I'm a freshman in high school then in the summer after my classes I could probably get close or a buggy version working. I just needed to know if any other developer already did it so I wouldn't waste my time.
Sent from my SPH-D700 using XDA App
It sounds more like it would need 2 partitions and some controller to pick which one at boot up but feasible since computers can do it.

Challenge accepted! Lol Cupcake on the Evo. Wonder how that would run being that the Evo specs are well above what's needed. I'm assuming, if someone is actually able to get it to boot cupcake, that it would run about as well as running Windows 95 on one of today's typical PC specs.
In regards to the toolbox and apps. Would the flash 11.x work on GB as well? I thought flash stopped at 10.x for GB and 11.x was for 4.x.x (ICS and up).

I think it does run on GB. When I flash a rom I flash this group of app along with it. It shows up in my apps when I boot up but I am not sure of the last time I used any flash on my phone. I usually use my pc for the Internet.
Op has some more info. I will be working on it more over the next few days. This will have apps, tweaks, and tricks. The apps are one part of the toolbox that will start showing up in our roms. They will also be included in a flashable zip for those who are not using our roms. The second part of the toolbox will be exclusive to our roms. It consists of modifications to the installer script that will put a copy of your recovery log into a folder on your sdcard. It will also do a md5sum of the rom you are installing and put that in the folder also.
Remember this is a work in progress so don't expect it to be finished over night.
Peace,
Love, and
Happiness
