[Galaxy Note II Q&A, Help & Troubleshooting] JoyMoro:
Hi RichMD..

Thanks a lot for your help. .

My both the problems solved. ie connecting phone to pc using MTP mode and cpu frequency stuck at highest.

All I did was flash ed N.E.A.K kernel and booted primary rom which is PA.

Then checked Cpu n MTP . All ok.

Then flashed Devils kernel. Booted primary. All ok.

Booted secondary . All ok

Thanks

my S pen did this. :D
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
Check the FAQs. /System is limited to 1.5GB. on the secondary ROM and your nandroid might have up to 2GB for / system. Try restoring to primary and backup apps and system data via TB. Then factory reset and back that up and restore to secondary. If that works, try restoring system data (safe on the same ROM) and a few key apps. If that works then start restoring others. Post your results and details if it fails.

thx for explaining this step by step so i dont need to read the whole bible online like the other thread! :)

i got 1 question for you! will this dual boot work with 1 stock rom and 1 costum rom or does it not support stock rom at the moment?

edit. it works but its buggy! im not trying neo's (the matrix :D) other recommendation as he stated:

For now, you should be able to install a 4.1 ROM on the secondary partition and a 4.2 on the primary partition. The most reliable method to not have problems (so far) is to install the "secondary" ROM to primary, boot up, get everything working, back it up, restore it to the secondary partition and THEN flash the Dual-boot kernel again (not when you first get prompted after the install). Post if you still have problems or even if you are all set.

Yeah....works well
[Galaxy Note II Q&A, Help & Troubleshooting] andrewjt19:
I've found that if I wipe the cache/DC and data then try to restart, it sometimes works. If that doesn't work, try doing a nandroid restore to the primary partition and reboot.. Then wipe the data, reboot, wipe, flash new Rom... I've dinked around with different combinations and one always works eventually.

I hv got an update to the secondary sammy rom...how do I install it??
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
I'm not sure if you would normally "dirty flash" or install clean but either way, it is just like installing any ROM - assuming it is a full ROM install and not something you have to install over a base. You can try the "Install ROM to secondary" option. However, that will not work for AROMA installers and potentially other install scripts. Even if it works, you might have a problem with MTP if you don't install to primary first. That might be fixed in the latest kernel versions. I'm not sure. However, if you have a problem,

1) Do a nandroid backup of your primary

2) If doing a "clean install", wipe for new ROM install

3) Install your update to primary, check to make sure everything works

4) Flash the DB kernel

5) Do a nandroid backup and restore it to the secondary.

6) Restore your previous Primary ROM

If you want to do a "dirty flash" then you could backup your current secondary and restore it to primary after step 2 above and before you install the update.

If your "update" is something that has to be installed over base then you could try "rom to secondary". However, "potentially" the "zip to secondary" might work depending on what is in the install script. If neither of those work for an "update" zip then you might have to flash the base ROM as I listed above and then flash the update and confirm it is working and then backup and restore to secondary.

Hopefully this helps and please post your results on what worked or not and what you were flashing. Good luck.

Thank you for this great tutorial and thank you RichMd for your original tutorial. I would like to know if there is a way I can have MTP on both fs. I currently have it on my second partition using the second part of this tutorial but would also like on my first. If this have already been asnwered I aplogize but any help would be appreaciated. Thanks.
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
What are you flashing as the primary - aosp or TW? Are you booting the ROM first with the included kernel and testing MTP before flashing the DB kernel again? Have you tried a TW ROM to get it working and then flashed AOSP over it - assuming it is AOSP you want on primary?
[Galaxy Note II Q&A, Help & Troubleshooting] pmaxis00:
TW as primary and aosp as secondary. With aosp I have a backup that has the kernel. And TW no kernel. What I did was I used a tw backup to flash as primary and the aosp as secondary. Could I install a fresh copy of tw and boot with included kernel, make sure everything works and install devil kernel then back it up? That is what I did with my aosp image.
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
Yes. Also, just to make sure you realize the kernel is shared between the ROMs and if you did a nandroid backup, it will include the kernel unless you did a custom backup.

Is there a particular way to update one of the ROMs loaded in dual boot? I have a TW ROM in ROM1 and aosp in 2. If I wanted to update ROM2 (for instance with a nightly) how would I go about doing that?

Thank you BTW for everyone contributing to this help thread I got everything up and running just want to see how to update a ROM
[Galaxy Note II Q&A, Help & Troubleshooting] jeremiahEJ54:
My understanding and if I recall I have done this myself

in recovery go to dual boot menu, mount the second fs, go back to first menu

if you are going to do a clean install do a factory reset option, choose to reinstall a rom, then go out to main menu choose install zip, and choose install rom

if you are going to dirty flash, wipe cache wipe delvack under advance, then install zip and choose install rom

Either way you will have to flash the kernel again after flashing the rom

I have run into the need to reenable the second fs after some flashes if sdcard can't be mounted

Hope that helps and doesn't confuse
[Galaxy Note II Q&A, Help & Troubleshooting] greenguggu:
Well I've found a way to update the primary rom...all u have to do is just flash another recovery once...do the updating...and then flash the dual boot recovery...but im still finding a way out to update the secondary rom...something easier!!
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
You should not have to install a different recovery to update either ROM. If you tried installing an "update" zip to ROM 1 and it didn't work then my guess is that you did not go into mounts and storage and select "Mount System" after selecting "Enable primary" in the dual-boot menu. /System is not mounted automatically. Full ROM installs typically do it anyway but a simple update zip may not.

For updating the secondary ROM, if it is an "update" (not full ROM install) then select "enable secondary" in the dual-boot menu and then select "mount /system" in mounts and storage. Then choose zip to secondary. If this does not work then please provide more details on what exactly you are flashing and what happens.

If you are trying to flash a full ROM install as an "update" to the secondary and it uses AROMA then you will probably need to restore secondary to primary, perform the update, backup and restore to secondary, restore the original primary.
[Galaxy Note II Q&A, Help & Troubleshooting] greenguggu:
Well I'll try and tell you asap!
[Galaxy Note II Q&A, Help & Troubleshooting] jahnbodah:
Are there any downsides to this? Im afraid if I have a TW rom and an AOSP rom, I will run out of space for apps really fast since I would have to the apps on each rom.

the other thing I worry about, is whenever I have tried aosp roms, it creates a new folder in my SD card and puts my whole SD card in that folder... Im wondering how/if it would affect using the SD card from both roms.

(currently using SKYnote 9.2 att rom on tmobile note 2, and I plan on running skynote/paranoid android - or aokp)

Also, at one point, I thought I read that you ABSOLUTELY HAD to put TW rom for secondary, and AOSP for primary, is that still the case or did that change?

and yes, I do have an SD card in the phone, lol
[Galaxy Note II Q&A, Help & Troubleshooting] jahnbodah:
Alright, so I had twrp installed, created a nandroid, reboot back to recovery, installed the kernel, and the dual recovery, reboot to recovery, made another nandroid with the dual recovery. Then I went to dual boot menu, hit the create secondary... and it said something like e: not found. Rebooted to Rom. Boot to recovery, dual menu, mount secondary, hit create secondary, and the screen flash and hours back to recovery main menu. Tried many things multiple times, whenever I hit create secondary it just goes back to recovery main menu.

At no point have I wiped anything... could that be my issue? I was hoping to just keep my current Rom as is.
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
Your SD card has 2GB of "internal" storage for /system, etc. The secondary ROM will have 1.5GB for /system, etc and that 1.5GB is taken from the remainder of your internal SD card (~11GB). Other than the 2GB and 1.5GB mentioned, the remainder (~11GB) and any external SD is shared between the ROMs. It takes a LOT of app installs to chew up 1.5GB. Most apps that download additional content (wallpapers, music, etc) will store them on the shared storage. You don't need a 64GB card as mentioned. I have a 32GB external which is more than enough for me - it was before I was dual-booting and that didn't change. You are correct that early versions of the kernel required TW on the secondary to have everything work but that is no longer the case.
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
I assume you just yesterday downloaded the kernel and recovery DerTeufel posted in his OP - correct? If it created the secondary partition, you should see ".secondrom" under /data/media. Do you see anything there?
[Galaxy Note II Q&A, Help & Troubleshooting] jahnbodah:
I got it working, I ended up flashing cm10.1 nightly to partition 1 and nandroid sky note (touchwiz) to partition 2. They both boot. And its working... Mostly OK. Seems like battery drain on cm10.1 is kind of high... Haven't used touchwiz ROM much yet... Is there anyone else that has had high battery drain?
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
Did you leave the CM kernel until you booted it and it was working? Flashing the dual-boot kernel right after flashing a ROM has caused the CPU to stick at 1600 which would cause the battery drain.
[Galaxy Note II Q&A, Help & Troubleshooting] jahnbodah:
That is probably it... I will dirty flash cm10.1 and boot, then go back and flash devil kernel.

Hi, I keep getting ' E:unknow volume for path [/data]' when trying to make the secondary partition?
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
I'll add it to the FAQ but that is common on many installs. Please check /data/media for the .secondrom folder which will indicate it actually succeeded regardless of that message. Post your results and I will update.
[Galaxy Note II Q&A, Help & Troubleshooting] mha93:
I can't find any .secondrom folder. And I can't switch on to my wifi :|

Also, before that, I can't mount my external SD card via CWR. I thought it was my CWR version's fault. Could it be a result of my SD card? Or do I have to make a fresh install?
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
So before you even get dual-boot setup it sounds like you have problems with your existing ROM regarding WIFI. You aren't saying dual boot caused that = correct? You are using DerTeufel's latest recovery and you can't mount the external SD or create the secondary partition?

Please list full details such as below.

Which model phone?

Have you flashed the latest DB kernel?

What version does your recovery say?

How much space do you have on your internal SD card? You need at LEAST 1.5 GB free.

What steps are you doing in recovery?
[Galaxy Note II Q&A, Help & Troubleshooting] mha93:
My rom is Rootbox vanilla. The wifi is okay before that, only after I reboot several times after the 'unknown volume for part problem' did I noticed that my phone is acting weird. Its okay now since I reflashed another version of CWR and restored from a back up. I suspect it could be the lack of memory that's causing all this weird issues. I'll try again and see how it goes. Oh and yeah I did used the latests DB kernel amd recovery.

Can someone help me I can't flash 4.2 to secondary btw It's first time flashing 4.2 on my device ever
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
Have you flashed 4.1 ROMs before? I would first do a nandroid of your primary and install 4.2 to primary to get it working and then backup/restore to secondary. I can help but you need to provide more info on your current setup and where you are stuck.
[Galaxy Note II Q&A, Help & Troubleshooting] Thealshear:
My current setup stock rooted firmware with devil kernel and recovery. I follow the steps I install pa rom to secondary and flash the kernel everything is successful. Then I reboot secondary rom I am stuck in a bootloop
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
Check the OP FAQs regarding problems with secondary. Again, I would suggest backup your current, flash PA AND boot it with the included kernel first. Ensure it is working, then flash the devil kernel and boot to ensure everything works still. Then back it up and restore to secondary. Boot secondary to make sure it is set and then restore your primary.
[Galaxy Note II Q&A, Help & Troubleshooting] mha93:
Okay so I bought a new microSD card and clean flashed everything and tried to do this all over again but the problem still persists. I still can't mount and create the second partition and I'll get the "E:unknow volume for path [/data]" error every time I try to do so.

I have Galaxy Note 2 LTE, N7105. As of this writing, I'm using the latest DB kernel and Recovery that's linked on the original thread. I have at least 3GB of internal memory and I'm stuck at step 6.

Also, about the wifi issue, I think it occurred due to the process still being halfway through.
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
If you use a root file explorer and you don't see the . secondrom folder under /data/media then I suggest you post in DerTeufel's thread. Sorry, but I don't know what else you can try. :(

Edit: have you tried saving what you want on a PC and formatting your internal SD card? When you clean flashed, did you wipe /system before installing the new ROM?

If I understand what you are asking, the answer is NO, creating the 2nd partition a second time will not use additional space.

Hi

I tried this kernel when dualboot wasn't available yet. Today I'd like to test it again but I don't want dualboot.

Is DB activated right after installation?
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
Definitely not. Plenty of people are using it for single boot - AOSP or TW. The kernel will support dual-boot but it will only try to boot a secondary if other configuration steps have been performed via the special DB recovery. You can use standard recoveries with it (TWRP or CWM).

I want to install paranoid Android(4.3) or slim bean as secondary rom and omega or rooted stock as primary rom

1)is it possible to dual boot a 4.3 ROM(I know that a single 4.3 ROM boots)

2)what is the best way to format and/or prepare my SD card(internal) for dual boot

3)is it possible to install secondary ROM on ext SD card(I couldn't figure it out in the recovery)

[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
1) 4.3 is currently only supported for single-boot (primary)

2) Leaving 4.3 out you don't need to do anything special on the internal SD other than ensure you have at LEAST 1.5GB free since the secondary ROM is stored in a new dedicated folder.

3) Sorry but not officially/directly. It's "possible" I think using some folder redirection, etc. but I don't know exactly how IF it actually would work. :what:

[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
I am not familiar with JellyBomb 19. However, I assume you mean you have tried running the install from external or internal SD rather than an install location - correct?

You are using DerTeufel's latest kernel and recovery?

You are choosing ROM to Primary AFTER selecting "enable mounting primary" (or close to that) in the Dual-boot menu?

I have an Idea, could you use internal storage or sth. like that for the "SD" part or sth. like that to avoid confusion...
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
I think you are saying to use "internal storage" rather than internal SD but what is "sth."? Also, internal storage could be confused with the 2-3GB for apps and data which is a subset of the internal SD. I tend to think of "internal storage" for the app installs, internal SD for music, photos, additional app data, etc. and external SD also. I appreciate any suggestions though to clarify it.
[Galaxy Note II Q&A, Help & Troubleshooting] My1xT:
for one point the App Storage (as I like to call it) doesnt exist on recent devices like note 2.

also there is a passage where you used SD without internal or external, which makes it even more confusing...

sth.=something

that makes

to "Something like that"

you understand?
[Galaxy Note II Q&A, Help & Troubleshooting] RichMD:
OK, thanks. I never saw something abbreviated like that. The screenshot shows 11GB total since the remainder is for the app installs and data and ROM, modem, etc. - basically everything from the root minus what is under the sdcard folder (a subset of the physical/real 16GB internal SD). At least that is my understanding. I can't attach but it was a screenshot from the storage menu

I will make changes to not just list SD without specifying though. Also, I guess I could list a "glossary" of internal storage, internal SD, and external SD
