I have looked around and haven't seen anyone mention this so I thought I would post about it since I've been using it and thought it was cool. I hope others find this useful.
The thread I'm talking about: http://forum.xda-developers.com/note-4/general/dual-boot-n910f-snap-dragon-variant-t3065211
The original thread quoted by @aukhan: http://forum.xda-developers.com/showthread.php?t=2447534
All credit goes to the original developers for this tool.
Thanks to @aukhan, @rlorange, @chenxialong, and other contributors.
Download the first .apk (Dual Boot Patcher). That is the only app that you should need to complete the process. A video guide is posted by @aukhan here: https://www.youtube.com/watch?v=h_i3GW_s-VE&spfreload=10
That is the best walkthrough I've seen.
Since it was requested, I've made a video walkthrough of this process: https://youtu.be/5VzYED1hhUA
Basically you patch all of the .zip files that you would have flashed normally and then you flash them to a new ROM slot. If there are more questions that the video doesn't answer I'll be happy to answer them or post a better walkthrough if needed.
It should be noted that to switch back and forth you'll need to install the Dual Boot Patcher apk on both ROMs. This does not affect TWRP Recovery.
I have run this with JasmineROM as the primary and CM13 as the secondary as well as CM13 as primary and JasmineROM as Secondary. I currently have this set-up to try different ROMs without needing to completely wipe my phone and deal with backups/restores. I also use it to use CM13 as my primary while having stock options (S-Pen, Car BT, and other Samsung stuff) available in a quick reboot.
Edit:
More Specific Instructions:
1) Download all .zip files that you would flash if you were going to flash the ROM normally (ex. CM13, Gapps, SuperSu, XPosed, datafixes, kernels, etc)
2) Download the Dual Boot Patcher apk: https://snapshots.noobdev.io/ and install it on your phone
3) Open ES File Explorer or another Root Explorer app and navigate to /sdcard/MultiBoot
4) Create a folder labeled "dual" in that directory (now there is a folder /sdcard/MultiBoot/dual)
5) Open Dual Boot Patcher app and tap the three lines in the upper left then select "Patch Zip File"
6) Tap the plus button and find each of the .zip files that you will be flashing. After selecting one make sure to change "Partition Configuration" to "Secondary"
7) A file browser will now open. Navigate to /sdcard/MultiBoot/dual and save the patched zip file there.
8) You may now repeat steps 6 and 7 to add the rest of the zip files
9) Tap the check mark in the upper right to "Patch" all of the .zip files
10) Tap the three lines in the upper left again and select ROMs
11) Tap the phone icon in the lower right and push okay
12) Tap the plus button in the lower right and navigate to the /sdcard/MultiBoot/dual folder. Select the main ROM (CM13, Kyubi, JasmineROM, etc) and tap "keep location"
13) Repeat step 12 until all zips are added in the order you want them flashed (the order is important). If you mess up swipe the one that's wrong to the right to remove it from the list
14) Tap the check mark in the upper right. A console should appear and it should virtually flash the ROM as you would expect in TWRP
15) Once it says "x/x completed" in cyan text and it has stopped you can just tap the back arrow in the upper left
16) If you go back to the ROMs page there should now be a "Secondary" ROM. To test it out you'll need to select it and then reboot the phone.
17) Once it has booted and you are past the setup you'll need to enable "unknown sources" in the menu and install Dual Boot Patcher. Once it's installed, open it. It should find the two ROMs and you'll be able to select Primary from the ROMs menu and reboot back
Edit 2:
This process can be done using any of the partition configurations listed when patching a Zip file. Secondary and Multi Slots go to the System partition, data slot goes to internal storage, and Extsd slot goes to the External SD card. I recommend not using the Multi Slots since more than two ROMs is a lot on the system partition.
If you have problems make sure to set the kernel and update the ramdisk before flashing and that the files are in the right folder typed exactly as it says in the prompt when patching the file.
I have noticed many problems when using a non-Touchwiz ROM as stock and trying to dual boot to a Touchwiz ROM. I have had bootloop situations when trying to dual boot to Kyubi or PaulPizz from CM13, but with PaulPizz as primary I have no issues switching back and forth.
In the event of a bootloop you can recover your primary ROM by entering TWRP, tapping install, selecting image in the bottom right corner, navigating to the /sdcard/MultiBoot/primary folder, and selecting the "boot.img" file. This will return your phone back to the primary ROM.
Edit 3: Video Tutorial: https://youtu.be/5VzYED1hhUA
If it is too blurry I can make another one, but I think you can see what you need to just fine. I hope it helps. I also forgot to mention that if you later want to flash anything to the ROM that you're "dual booting" into then all you have to do is patch the zip files and flash them like before except you're flashing to a slot that already has a ROM now.
Edit 4: I have now tested this on Marshmallow with success. I still recommend using a Touchwiz ROM as primary and you'll need to have a kernel that's permissive. I'm using Emotion, but I think Oscar's kernel should work as well. I have PaulPizzRom.VRU2CPF3.r-2 installed as primary with the CPF3 modem and Emotion kernel and CM13 as secondary (pretty much my daily driver at this point). Everything has been working so far.
Isn't there a kernel patch requirement for this to work?
Just tried it and working great for me. Jasmine primary, cm13 secondary. Definitely easier than messing with twrp to test roms. Thanks for the info!

I didn't need one to get this to work. You may be thinking of Multisystem, which is different and requires both ROMs to run the same kernel.
As far as I can tell this method boots each ROM with its own kernel. CM13 and JasmineROM both use a version of the Multisystem kernel, but I just checked and they are running different kernels.
I'll probably try the PaulPizz or Kyubi ROMs since I've been having some freeze issues with JasmineROM and see if the others work just as well.

Awesome, thanks! I'm definitely going to give it a try.
I cannot seem to get it to recognize the path with the patched ROM file. none of the storage paths on my device show as "sdcard", they are either sdcard0 or ExtSdCard.
Even though the folder structure is created on the Internal storage, the DualBoot app does not recognize it.
EDIT: Nevermind, I realized I do not need that app. I just patched the ROM and then added it in the Patcher app mentioned above. The added the patched ROM to it and it shows up in the ROMs menu
EDIT2: This is just not working, I try and apply the ROM for dual boot/swap, however it fails to complete the configuration. I am on a rooted stock phone..could that be the issue?

I just wanted to give an update and say I tried Kyubi ROM the other day and got it to boot just fine. I had one time where I needed to pull the battery, but then it rebooted to Kyubi and ran normally. I don't know if that was just bad luck or something else. I'm planning on trying PaulPizz's ROM today.

I added some better instructions in the OP. Can you tell me what step you're having problems with? JasmineROM is pretty close to stock so I assumed this would work just as well on the PaulPizz or stock ROM, but I personally haven't tried on either yet.

I'll give it a try with the more specific steps. I think part of my issue was all the videos and other walk-throughs are with older versions of the software. I was also trying to use the other Dual Boot app that is in the other posts....that is where I had the path name issue.
I was finally able to get CM13 on the list of ROMs, however it would fail to switch to it....but that was using the Win32 app to patch it. I'll try it all with the phone app.

I'll have to look at it tomorrow when I have time. You said you were on stock. What exactly are you running on your phone? What are the firmware version and the kernel? Also, how much free space is on your internal storage and are you using an SD card?

Try deleting all of the patched zip files and starting over. In the ROMs menu tap the three dots on the primary ROM and scroll down to the bottom. Update the ramdisk and set the kernel then reboot. Make a new folder in the sdcard/MultiBoot folder labeled "data-slot-1" all lowercase. Patch your .zip files and instead of selecting secondary select "Data Slot" and when it asks you what slot name, type "1". After tapping continue, navigate to the sdcard/MultiBoot/data-slot-1 folder and save the .zip files there. After the first time you should be able to select "1 (Data Slot)" for partition configuration instead of manually assigning one for subsequent .zips. Once you're done patching the files go back to the ROMs page and add a ROM then the .zips (selecting keep location like before) and see if that works.
The dual slot saves all ROM data to your system partition which could be pretty full even if your internal storage shows plenty of space. Since all apps are still on the system partition regardless of which slot you pick it may be good to look at how much free space is left before flashing. You can see how much space is left by tapping "Free Space" underneath the "Patch Zip File" button. The /system directory is your system partition.

My system partition says "Total size: 3.94 GiB, Free: 569.43 MiB" and that's with CM13 on Primary and PaulPizz on Secondary with Kyubi on data-slot-1. I haven't booted Kyubi yet so that may decrease my free space even further, but if your system partition is already full I don't think you'll be able to flash anything. You might try looking for big files in the /system directory. Also check to see if there are any files in /system/multiboot/dual and delete them. Do you have a lot of apps installed?

Mine says 56K free. Maybe I should revert to my nandroid which is pre-dualboot attempts and see. However I am on stock , rooted. Not even ROM, just the a rooted converter retail to DE. So perhaps the stock uses more system space.

That might be a good option. If I tap the three dots for each of my ROMs the PaulPizz (essentially stock) lists a system size of 2.09 GiB, which is half the size of the system partition. You might want to check yours and see what it lists as the system size.
You might also just try using the data-slot-1 and see if it works before the nandroid revert.

So that did work. Now I have a follow up question. Say I flash a ROM, like CM13 and GAPPS...but when I boot a bunch of apps keep FC'ing and they keep relaunching, like the SetupWizard...basically I'm stuck clicking OK on all the messsages and they just keep coming back.
My question...am I stuck? How can I flip back to booting to my primary ROM? can I delete the files from the data-slot-1 folder? Any thoughts?

It's actually pretty easy to revert back with TWRP. I was going to add this to the OP when I had time: Boot to recovery and tap install, then select image in the bottom right and navigate to /system/MultiBoot/Primary and select the boot.img, then flash it to the boot partition. That will let you boot to the primary ROM.

Hey everyone - I figured this might help some folks. It is a CWM installable zip that will restore your system to a completely stock UEKHA (the US retail build for P7310). This includes the stock kernel and recovery image as well.
Heres the instructions:
1) Download this file: http://www.multiupload.com/1KRF1M4CQZ
2) Put the file on your internal storage.
3) Reboot into recovery
4) Execute the Wipe Data/Factory Reset option
5) Choose Install Zip from SD Card
6) Choose Choose Zip from SD Card
7) Select the P7310UEKHA_Restock_v1.zip
8) Sit back, wait about 5 minutes
9) Once the script completes and says "Done", reboot.
10) Welcome to a completely stock US Retail tab
Enjoy.
I just want to ask: Can we flash this on other 8.9s from other regions (namely, an Asian model)?
I'm used to how it is in Maemo where the only differences between firmwares is localization and some preinstalled programs.
Yes you could flash it onto another 8.9 as well, although it should be a P7310 (Wifi only). Just like Maemo, the only differences between regions are localizations and pre-installed apps.
This stock image would not support 3G functionality however, so it would be a bad idea to install it on a P7300.
That's great. Going to flash Clockwork and this once I pick up my P7310 on Tuesday.
Which reminds me - how are Samsung kernels built? I heard that they need to use an initrd (or can the modules be compiled straight into the kernel? or is there a kernel size limitation, which is why an initrd is needed?)
I am truly grateful for this as I rooted and debloated my Tab the very first day lol. This is a great step!
Just flashed my tab with the ROM, works great! Originally had asian ROM on the tab.
Thank you very much! I needed some of the stock original loadable modules after some prior tweaks .
Thanks for the good work!
I was checking the system script used, and I was wondering if this CWM preserve the file/folder permissions as out of the box state or is just 7777 state?

Permissions should be out of the box state...the system image was taken from my stock tab directly, and the extract script should leave all permissions in tact.
Hey alterbridge86, it's great to hear you have a GT 8.9 now, that's good news for us
Quick question, how did you dump the ROM and the recovery? I have a GT 8.9 3G from Orange France and I'd like to dump everything before installing CWM to be able to restore to stock if needed.
Thanks! And again, great work!

I ended up dumping it using the CWM I posted in the other thread. The new clockworkmod stores its backups in .tar format, so it makes it really easy to manipulate. Simply create a backup, then if you're feeling adventurous, you can take this flashable zip, replace system.tar and boot.img with the ones created by your backup. The stock recovery is same on all devices, so you can leave the one that is in this package and itwill work for you
Sounds good, thanks I'll give it a try when I have a little more time to play
Hey guys, i did something really stupid today to my 8.9 p7310...I installed that Asia update to it and it placed the tab into a loop and crashes in the settings app when it first starts up. Cant access SD card to install this firmware. I need the Odin firmware to put back to stock I think. Any ideas?

When you installed the Asian firmware at ODIN, did you remember putting the CSC, PIT, BOOTLOADER to their corresponding places along with the biggest file being at PDA? If you just used the PDA file and not the other files...there's your issue. Once you successfully ODIN, flash this specific CWM Recovery and then you can either choose Stock (this thread) or the Overcome ROM.
Yea just did the pda. The instructions only said the pda. Doesnt matter anyway i am back to stock used adb to load the stock zip to sdcard and loaded

Help getting China based GT-7310 to US stock
Hello,
I recently bought a GT-7310 in China, and want to get this to stock US using your method. I had a question on step #2.
2) Put the file on your internal storage.
How do I get the file to the internal storage and where is that location? I don't see an /SDCARD folder anywhere when browsing the tab in Windows 7. I have the latest USB drivers installed. I tried to push the file to /SDCARD using ADB but Android SDK tools doesn't recognize my tab. Are there any other ways to get the file to internal storage?
Thanks.

When you plug in the tab, it connects via MTP to Windows. Then you can only get to the internal storage, just drop it in there. You'll see all the default folders (music, videos, etc.) so you'll know your in the right place.
Thank you. I got the file to SD Card, went into recovery, executed the wipe data/factory reset option. After the wipe data/factory reset is complete, I selected the option "apply update from /sdcard". I selected that and I get the following error:
E:error opening /data/media: No such file or directory
Any ideas?
Thanks.
You need to use CWM recovery, not the stock recovery.
THIS IS NOT CWM FLASHABLE. YOU MUST USE NVFLASH
Edit: It has come to my attention that the CWM is 5.5.0.2. This error has since been corrected. Sorry folks. I'm an idiot.
Hey, i hope this doesn't bother anyone but i compilied and easy zip for NVFLAshing the new CWM.
Thanks Fosser, Team DRH, and the BishopofTechnology (all of whoms work this is, i just put it in one place)
Included is the NVflashable info, the drivers for APX, and the new version of CWM.
Do this @ your own risk, i'm not responsible for any problems (i did test it three times, with each version of CWM, if that counts for anything)
Step 1) Get into APX mode (power + Vol-) [the screen will go black. that's what you want
Here's what the Bish says:
Step 2) Connect the GTab to the PC via the USB cable.
if your PC loads the USB driver and connects to the GTab, SKIP to the “Using NVFlash” section.
if the WINDOWS PC fails to load the driver, just click through Start/Control Panel/Device Manager and find “APX” listed in the devices with a yellow “!” (exclamation point) on the icon.
Select the APX item and find the “Update Driver” button and click it.
When it asks where to search, choose the “local computer” manual selection choice and tell it to Browse to the "Flash USB Drivers".
If you go back to Device Manager after the Windows install has completed, it will show the nVidia USB drivers near the top of the USB device list.
Click to expand...
Click to collapse
Step 3) Run the "nvflash_gtablet.bat"
A CMD prompt will pop up, let it do it's thing (don't stop or unplug during). Give it about a minute or until the CMD prompt disappears. You will the get a message that says "Entering NvFlash recovery mode / Nv3p Server"
At this point is should be okay to restart your tab. I'm running Flashback and had no problems staring up.
If you want to check the new CWM, hold the power + Vol+ when restarting and it should put you into recovery.
CONGRATS! You have the new recovery in preparation for ICS.
Once again, none of this is my work--i just put it into a convenient place.
Thanks again to all the Devs and enthusiasts. You make the Gtab worth having!
Edit 1:
Here is the MD5 check: 3DD468C48A3515E6E5A1C1236FF5068E
Edit 2:
The update recovery is with the normal sized Recovery.
Edit 3: 1) It seems this version partitions the external sd card when you choose to partition sd card. 2) choose zip from internal sdcard seems to use the internal memory 3) "FORMAT SDCARD" will FORMAT MICROSD CARD! YOU WERE WARNED
Alright. Download tested and verified. this is deff 5.5.0.4!
sorry again folks
Anyone that is interested in installing this via CWM, I created a CWM flashable verison from fosser2's download. Here is a link to the "normal font" version http://dl.dropbox.com/u/36150173/CWMR5504_recovery.zip. If you want the "big font" version, all you have to do is open the zip, delete the recovery.img, rename the Team DRM/fosser2/plastikman supplied version to recovery.zip & then add it to the zip.
I have installed this on 2 of my gTabs (one gTab Comb v3.3, the other CCCv8) and did not had any issue installing it this way.
Just a few notes on this version; it does give you the ability to flash from both the internal sd & external sd but uses a different naming convention though..."sdcard" is the name used for the external microsd slot and "internal sd" is what we would normally call sdcard. This version also appears to have fixed the "reboot recovery" bootloop bug of cwm3.0.2.8 (or aleast bypassed it)...when I selected "reboot recovery" it did the same as "reboot system now" (as I was doing this I crossed my fingers hoping it wasn't going to bootloop me...yea..no bootloop).
CWMR is touch capable. You scroll/select in 3 different ways...you can either use the capacitive buttons (which have been remapped to...Search is "select", Home is "scroll up", Menu is "Scroll down" and Back is "back"), you can also use the on screen touch controls (back, up, down & return), or you can also swipe up and down to scroll up/down and swipe sideway to select.
Al
PS:
WARNING: This is the beta6 release. The op page over in the Slatedroid gTablet Laboaratory says that selecting repartition will only repartition the EXTERNAL SD. Two users have reported magic value mismatch after repartioning with this version. plastikman, who created it says he is looking into it.
So u can install from the older cwm that's in flashback like any other zip?

Yes but beware of repartition bug

Yes you can. I installed on both mine from CWM 3.0.2.8.
Please note the warning I put on my previous post! It probably isn't a good ides to "repartition" with this version until plastikman finds the bug. If you need to repartition (which shouldn't be very oftern) you can always flash the old CWM (or stock recovery) via this version. The recoveries are so small that I keep a copy of each on the tablet just in case.
is the download ok i have try to unzip it and it gives me an error file is not a zip file

You don't need to unzip it but it does need to be a vailid zip.
Yes, the download is OK from dropbox. I just redownloaded it to my PC & tested the archive. No erors found.
I also put it on mediafire...try this link http://www.mediafire.com/download.php?qg3n084hfu783i2 & see if it's any different for you.

It shouldn't (and didn't for me). Are you sure you didn't select accidentally hit "reboot recovery" instead of "reboot system now" (since you were still in CWM3.0.2.8 untill you reboot)? If you did accidentally hit reboot recovery then it would have put you in a CWM bootloop.
There are 2 ways I've used to fixed a CWM bootloop (yes I've accidentally hit reboot recovery too)..one was is to use nvflash to format partition 7 (MSC) and the other way is to use CWM to flash stock recovery and then install CWM3.0.2.8 (for b/l1.2) via stock recovery. Formatting MSC is the fastest, but most people I suggest these fixes to choose to do the stock recovery route. If you want detailed instruction for either, let me know.

Great work and thanks for putting in one spot. I'll probably wait till a ICS ROM is released with but must say that this is a great first step till we get it. Cant wait for 10" of ICS....my cappy luvs ICS...

What does the recovery do when you don't have a microSD card in the slot. The /etc/recovery.fstab file is setup to fall back to using the internal SD card like CWM-4.0.1.5 is. Does it work on the internal SD card if no external one is present?

That procedure only works as a side effect. Simpler to wipe MSC directly. See post #3 of this thread.
Stash that zip file on you SD card, and if you accidentally select "Reboot recovery", just "flash" it to fix the always boots-to-recovery problem.
Just installed using CWM recovey and all is well. Just to test I took out my external sd card and when I went to update from sdcard it showed the content of the internal. So I am guessing that if one would decided to partition there internal sdcard they might need to pull there external out first. Then boot up recovery for there updates.

Just can't keep up with you raj...why did it take you 2 months to come up with the flashable msc format? Just kidding. I got the format msc from that very thread back in October. Everyone I've run into that is in a CWM loop I've given them the option of formating msc (via nvflash) or flashing stock recovery/then CWM. In every case they have always chosen to flash stock recovery & then flash 3028 (probably because most of the people I help are pretty new to the gTab). I think now they will choose the format via flash method. Thanks for the tip.
Just a question though. Exactly what is the CWM kernel writing to MSC to cause the loop? I assume it is the bootloader that checks for the rocker switch position & some mysterious bit on MSC to determine which kernel to load (but I'm just guessing). But if that is correct then why does flashing stock recovery, doing a normal boot & then flashing CWM fix the problem too (so I'm guessing I am wrong about my guess)? In any case can you explain why it works that way?

When ahead and changed back. When trying to downgrade to a 2.2 rom ended up with a mix match error on boot up. Looked good for what it is. Expecially liked the touch option on it, but it needs some work.

There are a couple of problems that I noticed with this version of CWM, and which might be responsible for your problems.
1. Roebeet's gtablet.cfg file which almost everybody uses to nvflash back to the 1.2 stock ROM has a bug in the system.img size calculation:
Code:
$ [B]fgrep size= roebeet.cfg[/B]
size=3145728
size=131072
size=2097152
size=131072
size=4194304
size=16777216
size=33554432
size=16777216
size=16777216
size=[B]259715200[/B]
size=0xFFFFFFFFFFFFFFFF
The second last line is the size of the "system" partition and it is misaligned. Every other partition is correctly rounded up to end at the gTablet's NAND flash erase size (128K). Compare with bekit's gtablet.cfg:
Code:
$ [B]fgrep size= bekit.cfg[/B]
size=3145728
size=131072
size=2097152
size=131072
size=4194304
size=16777216
size=33554432
size=16777216
size=16777216
size=[B]209715200[/B]
size=0xFFFFFFFFFFFFFFFF
Here all the partitions--including the last which uses the remaining available space--are rounded up to a 128K boundary. Looks like roebeet just added 50M to bekit's system.img size without rounding it up. The correct value should've been (using roebeet's system.img size as NUM):
Code:
$ [B]( NUM=$((259715200)); echo $(( (NUM + ((1<<17)-1)) & ~((1<<17)-1) )) )
[/B]259784704
--which brings us to problem no. 2:
2. The CWM-5.5.0.4 Beta 6 has a "cmdline" file containing NAND flash partition sizes which overrides the user's partition sizes read from the Partition Table. This is fine if the sizes are the same, but, a bad idea otherwise. In this CWM, the cmdline file sets "system" to be what we calculated above (259784704) but, which disagrees with the size in the PT (259715200).
Use the zip file in the attachment to empty the cmdline file out. This will cause the partition sizes to be read from the PT on the NAND flash.
My recommendation is that:
1. Users nvflash to 1.2 using either
a) the attached gtablet.cfg which has all the partitions correctly ending at 128K boundaries or
b) bekit's original gtablet.cfg. (This option is what I recommend. The "cache" partition is used for OTA updates and if it is much smaller than the "system" partition--like in roebeet's gtablet.cfg, then, depending on the size of the image, automatic updates might fail.)
2. Install the new CWM-5.5.0.4 Beta 6, and then immediately flash the attached zip file to empty out the cmdline file.

I looked at this sometime back and its complicated. I'll make a post on this later this weekend after I've looked at VS's newly posted 1.2 kernel patch.

For "mysterious bit" substitute "string", but, you are correct.

Thanks to rajeevp!!
Plastikman verified rajeevvp was correct and has issued an updated CWMR. Here it is in a flashable format http://dl.dropbox.com/u/36150173/CWMR5504_recovery.zip. He switched from using pershoot's kernel (which required the command line) to using the stock kernel. I tested the new version to install a rom, do a factory data reset, a wipe cache, a wipe dalvik & a fix permissions. All worked normally. Give it a try. I also corrected the links in my previous posts to point to the updated version.

Thank you. This worked well for me, since I was not inclined to do the nvflash thing. I was able to boot back into my Beasty+Clemsyn rom without incident. Tested by rebooting again and was able to boot into the rom with no issues.

... and in the process also brought back the always-reboots-into-recovery problem, right? Whereas with the pershoot kernel "Reboot Recovery" would just reboot the tablet into the ROM?
BTW, the pershoot kernel doesn't need a cmdline file: craigacgomez's CWM-4.0.1.5 too has a pershoot kernel and its cmdline file is empty. As I mentioned before: if the cmdline file is empty, then the bootloader will construct a cmd line for the kernel.
to install the cwm recovery do I simply transfer the zip to the internal sdcard and flash zip from sdcard as if it were a rom?

Hello, Ladies and Gentleman
Many people seem to have a hard time to understand how all of this here on XDA works. I constantly get PM's from users, asking how to do the most basic stuff like flashing a .zip or stock firmware via Odin. Usually, I don't even read them and just hit delete. I know it's not ok to deny people help, so I decided to show you how you can get Xposed working on your TW based stock or custom ROM since it's the most frequently asked question I get.
It's nothing you couldn't do if you'd just....
We're going to use @arter97's customized Xposed Framework as the one made by @darkera13 needs the user to manually modify and replace files which may be too complicated for some.
Preparation
-READ EVERYTHING OVER AND OVER AGAIN.
-A custom recovery System like TWRP or CWM (PhilZ or Stock)
-A deodexed ROM. It's the only way to go. YOU NEED A DEODEXED ROM. If your ROM is not deodexed and you flash the framework, you'll end up in a bootloop. To deodex your existing ROM carefully follow Post #2
Here are a few made by XDA Senior Member @_alexndr
Stock deodexed for SM-N9005 Galaxy Note 3 International Qualcomm.
Stock deodexed for SM-G900F Galaxy S5 International Qualcomm
-And the framework itself from here
[UNOFFICIAL] Xposed for Samsung Lollipop by arter97
-Flash a custom recovery system of your choice. This is listed under preperation on purpose since this guide is about getting Xposed on your TW Lollipop device. A guide on how to get a custom recovery system is most certainly available in your device's forum.
-Store the ROM and the Framework in an easy to find folder, which we're gonna call "folder x". It doesn't matter where you store it (ext. SD or int. SD)
The Fun Part
-Boot into your custom recovery and make a full wipe:
TWRP users: "Wipe>Advanced Wipe> Tick System, Data, Cache, Dalvik Cache> Slide to format.CWM users: "Mounts and Storage> hit Format /System; hit Format /Data; hit Format /Cache.
-Still in recovery system, install, or flash the files we put in folder x;
TWRP users: "Install> Navigate to folder x and choose the ROM file first> Add Zip> now choose the Xposed Framework from folder x> Slide to flash.CWM users: "Install Zip> Choose zip from /sdcard if folder x is on internalt storage or /storage/sdcard1 if folder x is on ext. storage (SD-Card)>choose the ROM file first> -Yes - install ROMXY.zip.Do the same with the Xposed Framework zip file.
-Still in recovery system, reboot device and wait for it to boot. It can take up to 20 minutes. Enjoy Xposed on your Samsung TouchWiz Lollipop ROM.
-Stuck in a bootloop? Try this and repeat the process.
XDA Senior Member @Honzze kindly pointed out to keep following in mind; You have to start JoelDroid Lollipop Batch Deodexer with Admin permissions. Otherwise this error might return "path variable" of Java "is not set".
Deodexing your existing ROM without having to flash an entire ROM
As the title says, with this awesome guide by XDA Senior Member @townsenk you don't have to reflash an entire new ROM to your device. Instead, youll just deodex those parts of your System which need to be modified in order to get Xposed working. You don't necessarily have to perform a full wipe if you do it this way. But if you encounter fc's or end up in a bootloop, you know what to do
Guide for this guide:
Regarding point 1: "...launch a DOS shell..." just means, you need to open the so called "CMD" programm in Windows. To "launch a DOS shell" or CMD from within a folder, you simply have to hold down the shift key and right click in that folder. The context menu will show an entry "open command window here". And that's it! (Windows XP users may have to search the internet for another solution)
For Galaxy S5 and Note 3 users: If ADB returns "device offline" or an empty line after "List of devices attached" make sure your using a USB 2.0 data cable on a USB 2.0 port

How to DeOdex YOUR (...) Rom.
I would like to note that I appreciate all the work that developers have put forth in creating and maintaining modified Roms. there are some awesome feature rich implementations available. My intentions are not to be critical of any specific Rom or mod. Without the developers we would have nothing.
(...)
This method is very common knowledge I thought I'd just explain it in an easy to understand way.
Here is what you need.
A stock (...) ROOTED configurated phone. Debloat as needed. Set the phone up exactly how you like it with apps and such.
Make sure it's stable. (If you have issues before DeOdexing they will be there afterward!)
Here's the files you may need to make this happen
LBD2.4.zip
7-Zip
Installer template (at end of post)
1> Make sure ADB is working on your computer. USB debugging turned on. Create a folder to store your soon to be download system files and launch a DOS shell from that working folder. Working folder name should NOT contain spaces. With the phone hooked up you should be able to type adb shell and get a prompt.
2> Type these commands
adb pull /system/app app/
adb pull /system/priv-app/ priv-app/
adb pull /system/framework framework/
This will take awhile and you will be left with three folders
Create a new folder named "system" and place these three folders inside.
3> Extract and launch LBD2.4 (This is the DeOdexer and is AWESOME). Point it at your recently created "system" folder and let it do it's thing.
I'll assume this will occur without errors as I have never had any.
4> At this point you can manually apply modded apk's to the system folder but I don't really recommend it. They can be applied afterward using the seperate installer zips.
5> with 7-Zip installed open the provided Installer template. Do not Extract it. Just open it in the 7-Zip file browser using the right click context menu in windows.
Drag-Drop the contents of your system folder into the empty system folder in the 7-Zip browser It should be the three folders previously created but now they are Deodexed. Close the 7-zip file manager and select Yes if it asks you to save.
Note: The provided installer template has been modified to only wipe and replace the three system directories.
6. Copy the created installer to your sdcard and install with recovery. Wipe cache and Dalvik before rebooting.
Go have lunch. You will sit at a boot screen for about 10 minutes. Then another 20 to rebuild caches. Time varies.
7. Your system will now be Deodexed! At this point you can install your mods one at a time, I recommend this so you can test your system between installs to determine if a specific mod is creating problems.
This method has so far removed ALL of my stability issues.

Since I no longer own this device, I'm retiring from this thread as of now. Hope I could help you.
Don't know if someone can help me as you stated that you're retired from this thread.
I did every step you do mentioned here (for self deodexing existing rom)
I did everything successfully and deodexed my files with 2.5 deodexer, putted files in the system folder to the 7zip folder and sent to my device and flashed zip, cleaned cache and dalvik and it stuck on booting for about 15 minutes. I know, it takes alot time during rebuildup of cache, but guys, it's 15 minutes! for me, if i cleanup cache and the dalvik/art cache, it just takes 1minute on boot screen to show up the image of each apps cache, but i just sat there with lots of patient for 15 minutes or a bit more and still same, stuck in same crappy booting logo.
I did restore my system files, now i'll try to retry it and send it again. Im suspicious of the zip file being corrupted during trasmitting to Device, however install was a big success so im very sure it wasnt corrupted. I'll do 2nd test and see it again if it's happening again.
If it does, i'll most likely try to figure out other ways to deodex as there is already deodexed roms out there, so they must have done is somehow.
Thanks, hope someone can help me out with this.
P.S: My adb works fine, i got usb drivers for my device, i got usb debug on, i got lots of space on phone, i got TWRP recovery which got very high compatibility when it comes to install anything from zip via recovery where almost all roms do work stable with TWRP.
omg brilliant @nitrous² ! thanks so much! its been days i keep trying to deodex with others tool...

Nope, i ended up using CM12 (at that time, right now i got cm13 update).
Well i had to deodex apps to get xposed on TouchWiz, but i failed and didn't get headache because of the Xposed modules being not really well compatible on TouchWiz, so i jumped to CM, i find it more stable, and the CM13 is insane because it saves so much battery at stand by, compared to lollipop, the Android 6.0.1 Marshmallow is the biggest update in android history, that saves hell lot of battery (it can be also maybe because i don't have Xposed Framework in recent rom).
Anyway, im tired of it, and i don't need to hassle with Link2Sd because of Android Marshmallow offering to mount the SD Card, in the end, all my needs are being offered in this (for me) huge, best android update, being Marshmallow.
Try it i would say, so amazing.
Ok i would like to go to cm13 as you but i stil need the support to the gear s smartwatch so i decided to stay with touchwiz without xposed.
Multiboot project is a work done by @chenxiaolong , I do not own any of the work presented over here.I just sent the author need logs.Support All Version
About Multiboot : A project to handle different ROMS at the same time so that you actually can use different ROMS without having to wipe up device to flash ROMS, it allows installation of more thn one ROM with all the features enabled.
USAGE1. First, boot into your primary ROM and install the Dual Boot Patcher app
2. Open the app and go to "Roms" in the navigation drawer. It will ask if you want to set the kernel. Make sure that you do.
3. Go to "Patch zip file" in the navigation drawer and patch the ROM or zip you want to install.
In-app flashing
To use in-app flashing, go to "Roms" in the navigation drawer, tap the floating button on the bottom right, and add the zips you want to install. You can queue multiple zips and they will all be flashed in one go. Once you've added all the zips you want to flash, click the check mark in the action bar and they will be flashed right away.
DOWNLOAD : https://snapshots.noobdev.io/(Added support 10.04)
ORIGINAL THREAD : http://forum.xda-developers.com/show....php?t=2447534
Manual
Step 1
download and install DualbootPatcher app
if you are in motion rom do this
Step 2
Open the app
Slide the menu and go to ROMs
It will request for root access
Allow the root access
and a message will ask about to set the kernel
Select "set now" and after it said kernel set now
Step 3
reboot your device
Now after device is turned on
Go to the app and navigate "Patch Zip File" from the menu
and tap that + button select zip of ROM you want to patch
A window will come up and if you see in "your device selected by default" you done everything right.
then:
If you are CMuser ( means you have a cm12.1 , cm11 or ... on your primary rom)
and want to install another cyanogeonmod rom (cm11 , cm12.1 ...)
Select the partition configuration as "Secondary"
If you are trying to install another ROM that has a huge system
Select partiton configuration as "data slot" and select an ID for the ROM
better to be a number
(It will be installed on data partition this means it will use the device internal storage space )
and select continue and set where to place patched file .
you can add more files to patch there .
and after you are ready to patch the files tap that tick button in action bar
to start patching
Step 4
After you patched the zip ROM go ahead and navigate to ROMs from the menu
select button down corner and select patched zip you patched
and then select keep location (or if you want you can change the location ) and add more patched zips or tap the up corner tick to start install
note : if any thing wrong happend PM me on telegram and send me multiboot.log in internal storage.
Step 5
after ROM is installed
it should be selected the installed rom .
tap and switch to primary rom
now use three dot on side of primary and select update ram disk
and then select reboot now
now after device rebooted go back to the app navigate to roms
now use three dot on side of new ROM you installed and select update ram disk
after it said done
select the rom you installed . ( tap on the icon of it or name )
( if you saw a message about checksum select continue )
reboot the device and see the magic !!!!
your new ROM is booting !!!!
Cool, let's stop enjoying and continue
Step 6
now after your new ROM booted
take your time to setup the device
and go and install dualboot patcher app again
now open the app
Go to ROMs and allow root access and
now use three dot menu in side of primary ROM and select update ramdisk
now use three dot in side of new ROM and select update ramdisk
and reboot
Soon there will be video instruction
NOTE:Support 4.2-6.0

INFO
Code:
Quick info
The patcher offers several locations for installing ROMs:
Primary: This is normally used for installing a zip to the primary ROM. It is not required, but is strongly recommended because it has code to prevent the zip from inadvertently affecting other ROMs.
Dual: Dual/Secondary is the first multiboot installation location. It installs to the system partition. This is a good spot for installing a second ROM because it doesn't take any space away from the internal storage.
Multi-slots: There are 3 multislots: multi-slot-1, multi-slot-2, multi-slot-3. These install to the cache partition. This is specifically for devices, like the Galaxy S4, that have a massive cache partition.
Data-slots: There can be an unlimited number of data slots. These install to the data partition and eat up space on the internal storage. This is useful for devices where the system partition is nearly full and the cache partition is tiny. These slots are named "data-slot-[id]", where "id" is something you provide in the app.
With that said, let's get to the "how to"!
First, boot into your primary ROM and install the Dual Boot Patcher app
Open the app and go to "Roms" in the navigation drawer. It will ask if you want to set the kernel. Make sure that you do.
Go to "Patch zip file" in the navigation drawer and patch the ROM or zip you want to install. You can select one of the installation locations described above.
There are two ways of flashing the patched zip file. You can either flash it normally from recovery or flash it using the in-app flashing feature. Both methods are explained below.
Flashing from recovery
To flash from recovery, just flash the patched zip file like you would for any other zip. Nice and simple.
In-app flashing
To use in-app flashing, go to "Roms" in the navigation drawer, tap the floating button on the bottom right, and add the zips you want to install. You can queue multiple zips and they will all be flashed in one go. Once you've added all the zips you want to flash, click the check mark in the action bar and they will be flashed right away.
App and data sharing
DualBootPatcher very recently got support for sharing apps and their data across ROMs. Maybe sharing is somewhat of a misleading term. The feature actually makes Android load the shared apps and data from a centralized location, /data/multiboot/_appsharing. So you're not sharing apps from one ROM to another per se. The ROMs are just loading the apps from one shared location. Let me make this clearer with an analogy.
Think of the people in a company office as ROMs. You want to share with your coworkers some documents (apps). Instead of telling them to come over to your desk to see those documents (sharing apps from one ROM to another), everyone goes to the conference room to look at the documents together (loading apps from a shared location). That's how app and data sharing is implemented.
To use app sharing, follow these steps in every ROM that you want to use app sharing:
Install the app you want to share
Open DualBootPatcher and go to "App Sharing" in the navigation drawer
Enable individual app sharing
Tap "Manage shared applications" and enable APK/data sharing for the app
Reboot
When you uninstall an app that's shared, it simply become unshared for the current ROM. That way, other ROMs are not affected. To continue the analogy above, if you quit your job, you won't shred the documents that everybody else was looking at.
If you unshare an app's data, it will go back to using the data it had before it was shared. In other words, you leave the conference room and go back to work on your own documents at your desk.
How do I...?
Switch the ROM if something doesn't work properly?
You can flash the DualBootUtilities zip from recovery. It will provide a menu interface that allows switching to the various ROMs.
If you have TWRP, you can also switch manually by tapping Install -> Images (bottom right) -> Go to /sdcard/MultiBoot/[Your ROM]/ -flash boot.img.
Wipe /cache, /data, /system, or dalvik-cache?
The easiest way is to do it from the app while booted in another ROM. Just go to "Roms" in the navigation drawer, tap the 3 dots options menu for the ROM you want to wipe, and tap "Wipe ROM".
Alternatively, flash the DualBootUtilities zip from recovery, which will also allow you to wipe a ROM.
NOTE: Don't use the recovery's built-in wiping abilities as that may delete non-primary ROMs!
Update the primary ROM?
Patch the zip for primary and flash it. The "primary" installation target is designed so that other ROMs won't be affected when you want to flash something for the primary ROM.
Update a non-primary ROM?
Patch and flash the zip exactly like how you did it the first time.
Flash a mod or custom kernel for the primary ROM?
Patch it for primary before flashing. If the zip does not wipe /cache, it is also safe to flash it directly.
Flash a mod or custom kernel for a non-primary ROM?
Just patch and flash it
thx so much inote 2 still not get work on it so sad
I'm proud to present the first dual boot project for the all Exynos7870 and Exynos7880-based Samsung devices. This project started off as a feature in my ROM, but not anymore. This will allow any number of ROMs to be installed at the same time. It works by patching the secondary ROM's installation scripts and boot image to load the ROM files from an alternate location (/system/multiboot, /cache/multiboot, and /data/multiboot). Because of the way this is implemented, no changes to the primary ROM are necessary
Donators
A huge thanks goes out to all of the donators for supporting this project! I if forgot to add you (and you want to be added), please send me a quick PM.
See all of our supporters here
It patches...
Custom kernels for dual boot support
ROMs so that they can be installed as secondary
Google Apps packages for AOSP-based ROMs
SuperSU so that it can be used in the secondary ROM
NOTE: If you want to dualboot a TouchWiz ROM, I highly recommend installing TW as the primary ROM. Otherwise, any mods will need to be patched before flashing.
How to use the patcher
Android
Download the patcher apk and run it. Tap "Patch Zip File" from the navigation drawer and choose the file you want to patch.
After patching the zip file, a new file, like some_rom_dual.zip file will be created. For example, patching ktoonsez's
KT-SGS4-JB4.3-AOSP-TMO-08.28.2013.zip
would create a new
KT-SGS4-JB4.3-AOSP-TMO-08.28.2013_dual.zip
Instructions for dual booting
Before doing anything, download the Dual Boot Patcher app and the DualBootUtilities.zip from the download section below.
The patcher offers several locations for installing ROMs:
Primary: This is normally used for installing a zip to the primary ROM. It is not required, but is strongly recommended because it has code to prevent the zip from inadvertently affecting other ROMs.
Dual: Dual/Secondary is the first multiboot installation location. It installs to the system partition. This is a good spot for installing a second ROM because it doesn't take any space away from the internal storage.
Multi-slots: There are 3 multislots: multi-slot-1, multi-slot-2, multi-slot-3. These install to the cache partition. This is specifically for devices, like the Galaxy S4, that have a massive cache partition.
Data-slots: There can be an unlimited number of data slots. These install to the data partition and eat up space on the internal storage. This is useful for devices where the system partition is nearly full and the cache partition is tiny. These slots are named "data-slot-[id]", where "id" is something you provide in the app.
Extsd-slots: There can be an unlimited number of extsd slots. These install to the external SD card, which is useful as it keeps the ROMs off of the internal storage. Note that the ROM's data files are still stored on the data partition.
With that said, let's get to the "how to"!
First, boot into your primary ROM and install the Dual Boot Patcher app
Open the app and go to "Roms" in the navigation drawer. It will ask if you want to set the kernel. Make sure that you do.
Go to "Patch zip file" in the navigation drawer and patch the ROM or zip you want to install. You can select one of the installation locations described above.
Well, Just flash the patched zip file via recovery (Custom Recovery, like TWRP of course)
A normal backup from recovery will backup every ROM. If you would like to back up ROMs individually, please see @rlorange's awesome tool: http://forum.xda-developers.com/showthread.php?t=2491299

got error 1 when flashing lineage as second rom
Tried it. It works if I flash the ROM from recovery but if I want to switch to primary using DualBoot utilities it doesn't work. Fortunately I had made a buk up...
One more thing : The secondary ROM detects the SD card as corrupted and needs formatting if installed to external storage :/
Can anybody help my?
I want to install second ROM on sd card, it will be perfect on ext4 separete partition.
I'v tried it.
I install second ROM on sd card (now it have only one partition vfat), but it cycle rebooting. Helps only restore from TWRP recovery.
DualBootUtilities..zip dont work and have an ERROR 1 in TWRP both 3.2.1.0 and 3.1.1.0.
My primary ROM is last oficial Android 6.0.1. , second ROM is [ROM] Stockrom Lite SM-A520F
Primary ROM rooted SuperSu, CSC - BTU, bootloader - A520FXXU4BRC4, PDA - A520FXXS2AQH1, Radio - A520FXXU4BRC1, ROM - A520FXXS4CRE1/A520FOXA4CRD3/A520FXXU4CRD3, Kernel 3.18.14-10911830 [email protected] #1 32-bit
Here is recovery log file

You need root for this to work. Do you have that?

Yes, I'm rooted with magisk. I wonder if it matters what version I am running. I am running stock 8.0 on an A520W.

Oh right. I don't know if op patched something about this, but originally touchwiz roms don't work with DualBoot, not even Hades.
Or, at least, I couldn't get it to work.

Ok, that makes sense, I tried a different version on my note5 and it didn't work either. The OP said to set Tw rom as primary though, is there a way to do that?
Edit: Would it work to flash lineage os, install dualboot, and then flash touchwiz as primary?
Do ROMs boot normally from an SD card? Or are they a bit slow?

Depends on the SD Card ;p
But, in my experience, SD is slower than internal memory
Where to get the DualBootUtilities? Cant find them in this thread. Can I use the official ones from the website? Or can I just install the App and im fine?

Did you fixed the error when going to ROMs? Im having the same error and I dont know what to do. Im rooted with magisk on Stock ROM 8.0

Try a custom ROM like lineage os and it should fix that error. However, when I updated ramdisk through dual boot on lineage os 16, my internal storage would quit showing up in stock file manager and downloads would fail. Haven't tried on any other ROM s though.

Great job ,thanks. I did'nt find the download link "DualBootUtilities.zip"
I am getting an error 1 while flashing a patched ROM. It looks like the ROMs aren't compatible by looking at the logs. Don't know if that is the correct verdict though.
