Oh really? do you pay them a salary every month? devs do this as a hobby they dont owe us anything nor do they have to share any of their roms mods or themes with us but they do.. could you try being a little grateful..and not act like a snotty spoiled kid that think that ppl are his servants.
Why is everybody ****ting on this idea? I think its awesome especially with the T-989. You can have a stock rom with WIFI calling when you need it, and cyanogenmod or whatever for the rest of the time.
You are almost a year late for the party...

Reason why Dual Boot is good
There are reason why dual boot is good
1.Don't need to worry hard brick(flashed to external sd, not in device):fingers-crossed:
2.Easy to test ROMs for developers because they can flash to sd card and boot from sd card. Also, developers does not need to mess up with hardware.
3.For people afraid of flashing ROM, dual boot is nice choice for them.:laughI am afraid of Flashing ROM also)
Sorry for my bad English.
Now this is the definition of dual boot http://m.androidcentral.com/samsung-ativ-q-puts-windows-android-single-tablet

That isn't exactly a dual booting app, but an app that overwrites your /system, /data and /cache partitions if I remember right. A true dual-boot mode would need to be baked into the kernel so that it can mount different /system, /data and /cache partitions on your device.
As was stated in an earlier post, it is nice because you can have some of those on your external SD card or internal SD card and have a failover in case something goes wrong with your ROM (ie your primary boot is your DD, your secondary is a non-DD or a new one and you hold vol+ while booting to go into it... usually it is a hotkey to boot secondary OR a menu like GRUB with a timeout). The problem is that in order to get that working, you need 2 partitions for your /system drive (one for each ROM). Most phones that support kernel-level dual boots have a partition we can borrow space from for the second /system (I believe the I9100 (could have the model wrong) uses partition 9, but our phones have that partition really small). I have looked around on the phone and currently cannot find a suitable alternate /system partition. It needs to be on internal memory as the external SD card mounts too late and you will get various kernel panics if it can't mount /system soon enough.
We COULD get dual boot working (in theory), but it would require stealing space from /sdcard (or /storage/sdcard0... they are the same device).. ie we would lose internal storage space. PLUS it would require some advanced steps preformed from the shell to do that and if you screw those up, you get a nice brick.
At least such is my understanding from reading various threads about dual-booting.
TL;DR: it is possible, but the chance of bricking is high.
Also, if you read the description to that app:
BootManager will not work with Samsung devices that are not listed because of the way Samsung handles the boot partition
and the SGH-T989 is NOT listed. Are you SURE that app works with our phone without screwing up the boot partition (or any other partition for that matter)?
I would love a dual boot feature. I use cyanogenmod and while it's great, samsung roms have MHL and wifi calling which would come in handy.

Ooo... I'm making progress on a dual boot option for our phones (YAY) bad news though is how it will work. If external ad it's present, not from it; else boot from internal.
Good news is that you can size your positions however you like though.
Bad news install steps are complex but I'm working on making it as user friendly as I can.
I'll link my post once I get it working and documented.

quick question about Partitioning my sd card...
does it make my G2 work faster with sense and other ROMS...or what does it really do for my phone?
Hmm I guess what you want to use it for would depend on what answer u get. If you want the old apps2sd method then ya you want to partition. But in general, partitioning it is not gonna change the speed of read write times or anything like thay. So if you don't have a reason to do it I would say no. Also some roms see swap/ext partitions and just assume upon using them which I never liked. So no don't do it unless you have a reason to...just me 2 cents which ain't worth much.

Hey guys..
Straight forward question..
Is it possible to password protect our Download and Recovery modes?
And i mean when you press and hold vol dwn+home+power method. Not through the android software reboot menu.
I want/like this idea because if someone were to steal my phone. They would NEVER be able to flash a custom ROM or even flash a stock ROM img. They would be completely locked out making the device useless to them.
The only way i think they could get past it is by using JTAG to overwrite the download partition with a stock one. But hardly anyone has a JTAG device.
Well this would be awesome. lol
Have at it
Im guessing it would require a modified bootloader. Not really sure though. Ive wondered about this myself. Never seen it done though.

that is a great idea indeed.:good:
Very interesting topic, but I think it is impossible to do (Recovery & download) are design to prevent forgotten password issues.
What a pity
Guys i thnk if it can be done
It will be easy to install it on our devices if rooted (stock android)
As companies like sammy ,htc have diff kernals
I thnk we can successfully do this fr nexus ,micromax ,karbonn etc.....
Lets have a try
Ny one tried this before
If so plz gimme a guide of it so that it will b easy fr me
Lemmi try my best fr us to have ultimate theft protection on our android devices
I hope if it wrks google may add it on its future devices
The "ultimative" protection would be:
When a phone is stolen, you can remotely trigger "the suicide button" xD
When it is triggered and the phone receives the command (Even if the phone is running other ROM) it reboots the phone and erases the Bootloader and some other things that are important for the phone to work.
Best. Protection. Ever.
Second thing I could imagine is that phone companies could protect the download mode with a password (12 digits or so).
That password will come printed on one of the manuals when you buy the phone.
If you attempt to flash an image in download mode, you will be prompted for the password.
And, optionally, if you put the password 10 times wrong, it will erase bootloader and etc.
Third idea: The download mode only will prompt for a password (printed on the manual), if you atempt to flash another ROM on it... Because this will change the confidential signature that the old ROM has passed to the download mode.
(I am not sure if this could be done. I'm just saying ideas...)

I have TWRP. I used to use CWM, but ever since getting my G4, that was what was only avail at the time. I really have to complaints on it though...other than the navigation from forlder to folder was easier on CWM.
Cwm is rock solid. Twrp has bugs(backup/restore especially) and lacks dev support.
Sent from my Nexus 4 using xda premium
Since OUDHS is based off CWM (IIRC), I'll have to say that. For the most part I've used CWM without problems anyway.
If you are using roms bssed off cyanogenmod... I say CWM but if your using TW roms go with TWRP

Wow. Didn't expect these comments. Here's my 2 cents. I started with cwm on my DX, then got touch cwm, then started to do aosp on all my phones really started with the gnex. Once I got my gnex ran aosp ever since. Have 3 s3,s as well. Twrp all the way. Never had issues and last checked it was faster. But then again. I haven't used cwm in years

I prefer TWRP, used to use CWM and it never failed me, so I will not complain, it's a preference. My bigger question would be, how would I move a file in recovery to another recovery if I wanted to have a few recovery options? Example, have the original backup on OUDHS and then switch to TWRP, how do you move that file? Sorry, not trying to hijack, but this thread seems like a good place for this kind of a question.
Had alot issues with twrp restoring nands, I went to cwm on my s3.
Twrp it points to backups that get put into the "0 "partition instead of the way it used to let u restore from external sd...in my opinion the multiple user partitions that now get created in custom recovery since jellbean is a huge headache. .. ive lost plenty of backups.. and no thanks to flashing cm10, downgrading to move all info back to internal storage is a train wreck ... I hate the way it is all set up now ..
Twrp benefit is its touch based and u can name your backups.
Cwm seems better but not as pretty.

Easiest way, save a backup with each recovery, that way, when the need arises to switch recoveries, you have it saved.

Hi everyone. Im new to the SGS2. I came from an SGS4G. I am not a developer but, consider myself an advanced user. Like the majority of. people on xda. Anyway, I think we'd get more people testing roms witn dual boot.
Edit: The Nook Color dual boots using cyanaboot boot loader. If the SGS2 uses the same method, a good chunk of the work may already be in place.

Can someone please point me to instructions for setting up apps 2 sd, or doing the internal v external sd swap?

I think that's an Android jb issue rather than a fault of the phone.

It's a ROM related issue (JB). I'm using Clean Master(App), which allowes to move at least some apps to external SD.
im using a custom rom with the memory swap baked in. But im pretty sure this is the mod/guide that im using
http://forum.xda-developers.com/showthread.php?t=2036796
it is really good and fools the phone into using your sd card as your internal memory so no need to swap on a per app basis.

Thanks for pointing me to this. Can you verify for me as I cant seem to find it. Can this be used on my stock rom rooted? Or will I need to flash a new rom? Id really like to keep it stock as much as possible. Dont mind if the trash has been removed though.
I know the thread says you need a rom and kernel that supports initD, but I dont know if this does?
Also, the initial thread indicates it needs to be a international version, mine is a US from verizon. Will this still work?
Lastly, im assuming I will need to whipe my phone and start fresh?
Again thanks for all the help with this!
I'm not a hundred percent sure to be honest. But I would expect it to work on a stock rooted phone.
You would need to do a complete wipe and I think it says in the op that you're better off using the mod as soon as you do a fresh install
However, seeing as you are with Verizon I would really advise you to Flash the rom I use, Which is the Jedi rom.
It comes with some trash removed, some nice eye candy, the swap already cooked in and the new kernel is giving standby battery performance of 1% an hour.
But if you do then I suggest you wait for version 18 which is due any day.
Good luck
