I'm not sure why the other roms booted but I know why DU doesn't. if you have secure booting error it means your kernel is not bumped. you should re-bump your primary kernel after every secondary rom install.

https://mirrors.c0urier.net/android/Dadi11/Required files/MR_Bump.zip

patch it for primary rom and flash. then you'll be able to boot every rom. and as you can see it is nothing on the rom-side
[G3 Themes and Apps] abeloman:
Yeah, as I told before, after sharpening mod, ROM boot fine and everything work flawlessly... Just wondering why happen "secure booting" but it doesn't matter, after bumping kernel everything is fine and now on I'll use your zip... Thanks for your patience, cheers!
[G3 Themes and Apps] cornelha:
You keep telling us to read the instructions and oddly enough it is ONE rom that doesn't boot, the one for which you are a maintainer. Every other rom that I tried works, except for Turbo (which just didnt flash at all). If the problem was that the primary rom kernel was not bumped, how come I am able to dual boot other roms? Tried with fulmics 5.2 as primary and with RR 6 as primary and same result. If you flashed one rom with this tool, it becomes a piece of a cake to remember how to flash another. DU works perfectly on it's own (except for contact sync being missing, but that is out of context) but I am unable to boot it even after flashing your bump script.
[G3 Themes and Apps] xstahsie:
Works great. thanks. Got the latest dual boot patcher apk from [MENTION=4277844]chenxiaolong[/MENTION] 's thread and got the stock ROM (not rooted) running as the secondary ROM. So glad I can now use the Android Pay app.

UPDATE: I can't seem to be able to get the secondary ROM (stock vs98574a) after rebooting into the primary ROM. The stock ROM just sits on the red Verizon loading screen. I tried leaving it on for a couple of hours, too. The only way back in is to clear the cache and dalvik cache but obviously, after booting back into the secondary ROM, the apps have to be optimized, which can take 30-45 mins to complete.

Does anyone know how to get the secondary ROM to boot properly? Hopefully [MENTION=4277844]chenxiaolong[/MENTION] can point me in the right direction.

UPDATE #2: I finally got Android Pay working with the secondary ROM (stock and unrooted). I have tested this at the store and vending machine and was able to pay with Android Pay. And I can switch back to my primary ROM (CM13) without any issues. Needless to say, my primary ROM is rooted and have Xposed installed. I can try to help or write up a full tutorial if anyone is interested in getting this.

hi, can anyone help me ? which one to choose in partition configuration selection ?

- primary rom upgrade

- secondary

- multislot 1,2,3,4

- data

after patching theres no Aroma menu during TWRP for partition selection (as mention in tutorial), the patched file install by itself which Im unable to install the gapps due error 70, so how do I select cache partition instead main partition ?
[G3 Themes and Apps] rosboy:
Has anyone had any success flashing fulmics 5.1 to secondary? I patched it and tried installing it in the app. It gave me a warning that aroma installer needs to run from recovery. Flashed in Recovery followed the fulmics aroma menu. Said it installed successfully. Tried rebooting was stuck on lg logo very long time and kept relooping to the lg logo. Used the utilities zip to switch back to primary. That worked but I got a service disabled no imei, or baseband. Flashed the stock MM Modem and got that back working.

Anyone can assist me in getting fulmics setup?

Edit: I had no problems with CM13 Rom
[G3 Themes and Apps] abeloman:
Seems only custom ROMs can be flashed as secondary... I've tried fulmics and prime without success
[G3 Themes and Apps] rosboy:
Thanks! Is there anyway I can try fulmics without losing my current stock setup? I spend hours customizing it with the mods I use. Do you know if MultiRom would work?
[G3 Themes and Apps] xstahsie:
Unfortunately, due to time constraint and the fact that I have moved on to the Nexus 6p, I will not be able to create a video tutorial.

However, if I recall correctly...

Step 1: create the secondary partition.

Step 2: flash a stock ROM (VS98545B or VS98546A should be work) after you have patched it. These should NOT be rooted, as it will break Android Pay after completing these steps.

Step 3: flash the stock VS98547A ROM by xdabbeb (dirty flash it) over the ROM that you just installed in step 2 and also flashed the 35B bootstack. (Here's the link to both the ROM and bootstack: http://xdaforums.com/verizon-lg-g3/development/vs985-46a-stock-flashable-firmware-t3304365)

Step 4: Boot into the secondary ROM.

See the instructions in these links (OP) on how to create the secondary partition and how to patch the files for flashing:

[MENTION=2555474]xstahsie[/MENTION] Where do I find a stock ROM without root (the initial ROM you said to install)? I am trying to boot a second ROM that will work with Android Pay and Good Works :)
[G3 Themes and Apps] xstahsie:
I wished you had asked me this a month ago.[emoji2]

I know I found them on XDA in the LG G3 Verizon forum. Download the stock ROM version I had mentioned (with root is fine). Once you have it installed on the 2nd partition, uninstall SuperSu, restart, and install Android Pay. Let me know if that works.
[G3 Themes and Apps] dbnaruto:
[MENTION=2555474]xstahsie[/MENTION] Okay thanks, I will try it. I'm traveling and the internet speeds here are terrible, so it will take an hour or two to even download the ROM, so I may not be able to say if it worked until tomorrow. I'm not familiar with systemless root, how do I uninstall it? Does it leave traces that I need to cleanup (more so because Good Works is really picky; I don't think Android Pay is as picky).
[G3 Themes and Apps] xstahsie:
I'm am not familiar with Good Works--only Android Pay.

After installing a stock ROM with root, you should see SuperSU in the app drawer. Launch the SuperSU app and go into the app settings; in there, you see an option to fully unroot the ROM.

Out of curiosity, do you own the Verizon variant of the G3?
[G3 Themes and Apps] dbnaruto:
[MENTION=2555474]xstahsie[/MENTION] Okay, I will try. And I do have the Verizon version

Edit: So I got the ROM and bootstack downloaded and patched, but I have not been able to boot into it. At first it was failing to install in the Secondary slot, but I think that it because I did not have enough room (I had 1.6GB, and while the .zip is 1.4GB, unpacked it is 2GB). So I installed it to a Data slot, but even after installing it and the bootstack (which both "succeed") when I boot into it, it just sits on the first LG boot screen, and then restarts into recovery. I can't seem to find out why xD
[G3 Themes and Apps] xstahsie:
I've not encountered this issue. The only issue that I encountered was the phone sitting on the boot animation screen.

What is the ROM that you are using? Could you provide link to where you got it from? Also, have you tried a different stock ROM?

Here are the ROMs and bootstack that I've patched myself that should get you going. After flashing these files (I forget which order), you should have a stock 47a firmware. You should be unable to go into SuperSU and uninstall root; once you do this, Android Pay should work.

I run Fulmics 6.6 as a base together with crDroid cm14. For me crDroid installed fine after flashing RADIO_D855_21C_Step-han.zip which can be found somewhere in the forums.

---------- Post added at 03:53 PM ---------- Previous post was at 03:44 PM ----------

A question that I have involves SECURE BOOT.

I have installed Fulmics 6.6 as primary without patching it for primary (when I patched it, installation did not work out). I then installed crDroid android 7.0 (from Oct. 21) to a data slot together with gapps.

Every time I want to boot into a rom (doesn't matter into which from where) I get the SECURE BOOT warning and I have to flash MR bump. I also installed MR bump separately to primary with a patched file. Switching betweem roms does work, but I have to flash MR bump every time, which is quite annoying.

Does anyone have a solution to this?
[G3 Themes and Apps] Antidote03:
i have the exactly same problem and i stopped using newer version of DBP .. Something wrong with the new one , u can use older one version 8

Thanks for your reply. I used this version DualBootPatcherAndroid-9.0.0.r56.ga5fde5c-snapshot. I will now try version 8.

I installed the latest 8: DualBootPatcherAndroid-8.0.0.r2709.g554d8f9-snapshot. I patched the files using that one and installed the latest crDroid to data, but I still have the same SECURE BOOT problems. The ramdisk can indeed be updated now.

Working great right now on the vs985. Stock ROM as primary and also Euphoria as secondary. Have been trying to get the app sharing working across ROMs but without any luck.

How do I set a different kernel for the Secondary ROM? Don't you have to flash a new Kernel to get two?

I don't want to mess anything up, so here is what I think might be the procedure:

Install patcher on primary, set kernel.

Patch rom zip and gapps zip.

Reboot to recovery and flash rom zip and gapps zip. Install to cache or system.

Reboot and go into Secondary, install patcher.

At this point, if the kernel is different than Primary (aosp vs stock) because it comes with the secondary ROM I just flashed, is it currently running the secondary kernel?

Do I have to set kernel to Secondary at this point?

Perhaps I'm just confusing this simply process by overthinking. I suppose since I have nandroid backup I can just fully restore in TWRP...
[G3 Themes and Apps] whoppe862005:
For a different kernel it says to patch it and flash and flash it. I'd recommend going to the original thread s4 thread and reading though that at least the OP.

[G3 Themes and Apps] Vivasanti:
Great work guys, thank you for bringing this to the G3, i have a couple of Q's...

1 - what is the advantage of installing it in /system rather than the cache partition?

2 - how do we fully remove it, like uninstall/remove the rom, is the only option to restore a nandroid backup? (fully remove all data)

Cheers.
[G3 Themes and Apps] xocomaox:
1 - You have more space (typically) in that partition than the cache partition.

2 - The only way I've found to remove the ROM from the system partition is to literally restore from nandroid backup. The wipe does not work.
[G3 Themes and Apps] lukas77:
2. Just delete /system/multiboot and /data/multiboot
[G3 Themes and Apps] xocomaox:
Through File explorer? This would remove all traces of the additional ROM?
[G3 Themes and Apps] lukas77:
Yes use file Explorer, DualBoot works this way:

- patched kernel/ramdisk booting up ROM from following locations /system/multiboot or /cache/multiboot and all your data is stored in /data/multiboot

- when you switch ROM from DualBoot app you actually flashing a kernel (eighter stock kernel to boot primary ROM or CM12 patched kernel to boot secondary)

- when you siwtch to primary ROM you can delete /system/multiboot or /cache/multiboot and /data/multiboot to completely remove second ROM

- additionally you can delete /sdcard/multiboot where only kernels are stored

[MENTION=4277844]chenxiaolong[/MENTION] correct me if I'm wrong ;)

Tip (time saver): if you stuck in second ROM because you didn't set kernel for Primary ROM and you cannot switch ROM, you can boot up Primary ROM by restoring only Boot via recovery.
[G3 Themes and Apps] chenxiaolong:
That's exactly right :) By the way, the app provides a way of wiping those files too:

I think it's because you flashed it for the other rom. Did you try to go to the rom you want to have gapps and go to recovery from there and than flash it.
[G3 Themes and Apps] lukas77:
Check if you have enough free space to flash gapps. If you have enough free space, then don't use pa_gapps, use cm12 instead.
