[How To] Two Roms on One Device

People have been asking in the dev forum alot about how to have two roms on the same device. So i thought I would make a how to.
You do this at your own risk.
Things Needed:
external SD
Get CWM for droid3
SafeStrap for droid3
stable rom to use as nonsafe [put on external SD]
rom to use as safe [put on external SD]
TiBu
1. (make sure you are in nonsafe, if you don't know what this means then dont worry). Do a backup of everything you will want to keep with TiBu.
2. Put the backup on external SD or on dropbox.
3. Uninstall any existing recoveries.
4. Reboot device.
5. Install cwm.
6. Reboot into CWM Recovery and install stable rom.
7. Reboot device.
8. Uninstall CWM and Then install safestrap.
9. Reboot into safestrap recovery.
10. Use volume rockers to go to safe boot menu.
11. Toggle safesystem.
12. select install a zip
13. choose safe rom
14. DONE "]
The nonsafe system will now contain your stable rom. and the safe system will contain your 'experimental' or second rom. I recommend not putting any new or buggy roms as your nonsafe. And this is already considered a dangerous thing to do. And give a huge thanks to hashcode for providing us with safestrap and koush for cwm :]
I currently use MavRom as a nonsafe. Its extremely stable and has not caused any issues at all.

Also if you want to transfer the safe to the nonsafe, use tibu to entirely back up the rom, system and user apps, you can then restore it after flashing it to nonsafe. Make a new backup folder to put it in so you don't mix it up with other backups from different roms

I can't seem to get this to work with Cm7 as Safe rom and Cm9 as my experimental. I got Steel Droid to boot up and stock but I'm starting to think any rom that isn't blur based (which is really only cyanogen) isn't able to be dual booted. I just get a black screen after the splash screen I've been trying for a week now. If anybody is willing to give it a shot just to see if its me then please let me know of your findings but Mavrom Liberty SD all of those I can boot its cm7.1 or Cm9 that won't...

Thwe blur based thing may be right. Im unsure, but cm7 to me personally shuld not be used as stable

Damnit man I would rather not have to run cm7 as my stable rom seeing how I have no front facing camera support but the other features that the blur based roms lack just make it impossible to use as a daily driver. I need control over which buttons are in the notification widget and a few of the other features cm provides and none of the blurless roms give me that unfortunately... I'm determined to get this to work if its the last thing I do lol

I can't get cm7 to boot up past the safestrap splash screen.... I start out with bootstrap boot cm7 up and then remove bootstrap and install safestrap thus making cm7 my non safe or main rom but upon rebooting the phone I just get the black screen after the splash screen... I can get into safestrap and switch to safe mode and run whatever rom I last had there or flash any nandroids I had in non safe mode but whatever rom I had on prior to installing safestrap (cm7 or cm9) they won't actually reboot. I thought cm9 would work which would really be a hastle keeping that as my non safe rom and cm7 as my main one on the safe side thus leaving me to redo the entire process everytime a new cm9 is released but cm9 wouldn't boot up past the initializing apps screen that first pops up... It counts up to all the apps I have then just stays stuck on starting applications or whatever it says, cm7 doesn't even boot up beyond the splash screen...
Edit: And I know that I'm doing it right because I have got Steel Droid to dual boot before I just can't understand y blurfree roms can't boot in non safe mode

Ok im gonna give this another shot tonight..... haven't had the time or patience especially since I think its gonna fail again but ill update with my progress.... gonna try cm7 as the non safe and aokp as the safe one...
Sent from my DROID3 using Tapatalk

Ok, time to feel like a total noob.
So, my idea was to use safestrap to install aokp on the safe partition and leave my stock (+root) rom on the unsafe one.
I had bootstrap installed, just to back up my stuff and whatnot, so, I uninstalled it, installed safestrap, put all the stuff needed for AOKP ( rom, gsm patch and gapps ) and rebooted the phone. I enabled the safe system, and flashed rom, patch and gapps. then I rebooted, and I got into a loop where I would see the motorola logo ( the still one, which says "dual core technology" or something like that), then I got the safestrap splashscreen and if I pressed search, or left the phone idle so it would boot on it's own, it would get me to the motorola logo again, and repeat the loop.
I had to go back to the unsafe system and luckily it's all still there, but, since that point I tried every combination that I could think off, with wipes and I've flashed even just the rom, between wipes, and still, nothing.
I'm thinking that safestrap is not being able to write on the partition, or something like that, but I don't know how to solve it.
Any Ideas?
EDIT: I checked with a root explorer on /preinstall ( which I understand is the /system folder for the safe system ) and all the data seems to be there, but it's just not booting. Which makes me even more confused

Some Roms just won't flash.

Hey,
I have a nexus, but my mate has the note. He is having all sorts of problems with it when it comes to flashing ROMs. I was hoping u smart people here might be able to help
What the problem is, is that only about one in 10 ROMs will install. He flashes the usual way... wipe everything, etc but either gets in a boot loop, or just Samsung comes up on the screen, it disappears and then comes back and this repeats. He has to then pull the battery. Another weird thing is that a ROM that may not have worked a few weeks ago, he tries it again and for some weird reason it works. So far he has never been able to flash an ICS ROM.
Any ideas? I've suggested to him to start completely afresh and use fast boot, etc again, but I'm no expert myself. I've never had any dramas myself with the nexus so this has me completely stumped....
Thanks
Dean
Swiped on my Gnex
Edit: sorry guys, he used Odin, not fast boot.

Maybe he dont follow the instructions correctly

What method is he using to flash? If using pc Odin does the flash get stuck at factoryfs. Img?
Was he on ics stock and did he perform any factory resets on it?
If answers are yes, it's likely he's got traces of damage on his emmc chip, but we need to know where the flash is failing to understand further.
Sent from my GT-N7000 using xda premium

No and no.
His phone came with GB. He downloads the ROMs using his computer then transfers the zip to then flash using CWM recovery.
He has tried lots of different ROMs. He tried to install a new ROM the other day but before doing so he deleted a few ROMs he still had on the SD card. He flashed the new ROM and it didn't work. He freaked coz he didn't do a backup first, but he tried installed the ROMs that were still on the SD card and found them all but one to work, and the one that worked was a ROM that he had tried before but didn't work then, but this time it did work...
What is happening? Is there something he can do?

Try flashing rom with pc odin instead of cwm.
Check out Dr ketan sticky thread in rom development for directions on how to use pc odin. It's simple.
Let us know how you progress.

Yes you must be on the Jellybean leak, rooted, with Safestrap 3.0 installed.

Well I rebooted without wiping data or cache and now my phone won't boot.
Cannot enter SS3 either..
So this is a must, not a suggestion.

For you it was a must, in my other experience it's a suggestion. Always wipe if unsure. I will note this in the OP, however.

Yes go into boot options (power and both volume buttons) bp tools

Thanks man , great to see some Custom ROM Action :good:
Will definitely try it over the weekend .

Did everything like the op said and ended up in a boot loop.So i had to go to ap fastboot and use the utility 1.0 to go back to stock and start over.Not sure what went wrong.Will try again and see what happens.

Hey matt. Nice ROM... it looks really cool. Thanks.
For ppl with unlocked BL are the steps the same. Mine is a bell model and cant update to the leaked jellybean. Also do i need safestrap?
I now there's only like 2 of us in this situation here... thnx in advance

unsuccesful on my end as well just stayed at the boot animation all night RSD saved me though i might try again later
edit** tried twice now and still no dice boot loopin on tablet mode

bootloop
tried tablet version and went into bootloop.....and what happened to the safe strap recovery because this sucks having to rsd, update, root all over again. can i just root, install recovery then restore MY ORIGINAL backup and i assume thats without data. this was a simple op nothing should have went wrong...maybe leave save strap in???

I'm a giddy lil' b#!&h for this! I can't wait to get the time to figure all of this out and get this GORGEOUS ROM runnin! Thanks Matt and Sirhoover for all your work and testing!

Well you can go to leaked Jellybean for AT&T if you are boot loader unlocked... You flash system and boot.IMG from ATT 77.12.22 then boot to stock recovery and install the jellybean leak after the normal root procedure ( root, ota root keeper, etc) see the threads for those Also might need to wipe data when flashing att files or boot loop.

For people having problems I hope you restored to a ROM Slot and wiped data/cache. This method has been tested by SirHoover2010 and he says it works.

It works.

Have you followed the proper installation instructions on every ROM you tested? (wiping Data and other partitions)
Do you also get the freezes when connected to your charger?

i install new rom following way
1.enter into recovery
2.format data
3.wipe cache
4.wipe partitions
5.wipe delvic cache

How about when the charger is connected? It may be your battery that is screwed up. Or maybe some rogue app that is consuming your resources.

Try to restore the smallest number of apps possible, always reinstall them from the play store. And NEVER restore system apps.
This should keep you free of your problems.

Help...My note just completely died (sgn 7000)

Was running RRv1 JB, woke up to a screen asking a question in german, no idea what it was. i rebooted and went into a "samsung galaxy note" boot loop. Rebooted recovery, and tried to dirty install RRv1 over the existing version, wiped davlik and cache partition first and then midway though the install my phone went black, never to show a flicker of light ever again.
It was at 100% charge when this all started, i tried replacing the battery with a spare...nothing. It doesnt seem to want to take a charge and there seems to be nothing I can do to get even a spark of life here.
thoughts? (help!)
Jason

U should have done full wipe, data, cache and dalvik all. Try doing it now if you can enter recovery...

I can't, the phone seems dead. I'm hoping for some insights in regards to that

no recovery, then I dont know. Did you flash a non n7000 rom on phone?
If you do have recovery, old known issue, perform the wipes on save kernel and reinstall rom should fix it.
Best go to different rom and or use Phills kernel with the fix included.
That should do it, all at own risk

I have no power, it won't take a charge, it won't turn on even when I put a fully charged battery in it.
I'm asking if anyone knows of a list of things to do when your phone is in this condition. Are there certain things to check by taking the phone apart, I'd there anything I might be able to do, or must I send it away to Samsung?
