You can also do a backup but only check the data partition. Delete the ROM, reflash as new and then restore the data backup

But typically you don't need to wipe system, I have even ran into cases where it causes problems
[Nexus 6  Original Android Development] demlv:
So it seems that Android Pay will never work on a custom rom, or even a rooted stock rom. Does anyone know if multirom will allow one to run a truly unmodified stock rom along with custom roms in other slots? Do the kernel modifications used by multirom prevent Android Pay from working?
[Nexus 6  Original Android Development] Droidphilev:
I have no idea but if you try: it should be in a secondary slot for sure.
[Nexus 6  Original Android Development] Droidphilev:
Hi,

Ok... the new 'systemless root' breaks Multirom (again). For now if you want a 6.0.1 rom as secondary please flash to primary and swap it. It did some other test and if you are willing to keep normal way of rooting then 6.0.1 roms are nor problem flashing as secondary. Seems that only flashing SuperSU 2.61 to secondary is the problem.
[Nexus 6  Original Android Development] demlv:
It's not clear to me what you are suggesting. Which rom would need to be in the secondary slot?

If it is the stock rom you believe should be installed as a secondary, the stock rom is not available as a .zip, so to get it installed as a secondary, I would need to fastboot flash the stock rom, then flash a compatible kernel to the primary (stock slot) in twrp , then use use multirom's swap rom function. Does that sound right?
[Nexus 6  Original Android Development] Droidphilev:
I mean the full/stock/stock/stock should be in secondary slot (as the kernel of the primary rom gets patched with the bootmanager menu. I *THINK* (don't kill me) the only thing you can try:

-completely remove Multirom

-Flash normal TWRP

-flash full stockistock rom

-make backup of this rom

-wipe

-put back your custom rom

-flash Multirom and Multirom TWRP

-restore the stockistock backup as secondary

You see this is a bit of work while i'm not sure that this will work.

(did you try that Pay thing on a rom with systemless root?)
[Nexus 6  Original Android Development] demlv:
Thanks for the outline. It makes sense to me, but it sounds like a weekend project that I may not get to until after the holidays.....

I have not personally tried the systemless option, but I have read of others and I have yet to see anyone reporting successful use of Android Pay, even with systemless root.

EDIT: Immediately after posting, I saw that someone had a few weeks ago confirmed Android Pay working on Chroma rom using a weird combination of a systemless boot.img but a regular, flashable .zip version of Chainfire's SU: http://xdaforums.com/showpost.php?p=63875645&postcount=725
[Nexus 6  Original Android Development] Droidphilev:
Well... can't help you with it right away as maybe in 50 years we will have Pay here. did a fast search and it seems you can't even edit something in build.prop or it breaks Pay.

---------- Post added at 07:45 PM ---------- Previous post was at 07:41 PM ----------

that's 6P! Here's what Zephikk wrote about n6:

"I recommend SuperSU, it's what works and is known to work. I've used it for a long time now so it's nothing new. With 12/06, I made a formal post on how to use systemless root but seeing that Android Pay only works on 5X/6P, it's meaningless to use systemless root on a N6"

EDIT2: SuperSU 2.56 was the first systemless root SuperSU. They are all flashable.
[Nexus 6  Original Android Development] demlv:
Just noticed that too (N6P not N6). The initial thought holds....no report of Android Pay working with root, regular or systemless, on any N6. So I expect to eventually try out your plan to see if I can get the unmodified unrooted stock rom working in a secondary slot.
[Nexus 6  Original Android Development] Droidphilev:
Let us know! :)
[Nexus 6  Original Android Development] H4X0R46:
So if I understand this right, having Android 6.0.1 installed with Supsersu 2.61 systemless root breaks the current multirom? Having 6.0.1 installed as primary and not moved to secondary of course.
[Nexus 6  Original Android Development] amritanshu001:
Have Chroma 6.0.1 on secondary directly, but not with super su 2.61. I am still with traditional root because

A. Pay does not work in my country

B. Even with 2.61 root pay does not seem to work on shamu. Looks to be working only with 6p and 5.
[Nexus 6  Original Android Development] Droidphilev:
Hi,

Correct. Only flashing supersu 2.61 is a problem. You can swap thou OR use 'old' root method
[Nexus 6  Original Android Development] H4X0R46:
So multirom does work but flashing the new supersu doesn't currently work for secondaries? Does the multirom menu that's in boot.img come up and function correctly when you have systemless root installed? (primary). Or is this another issue that needs a different root method? (Traditional root)
[Nexus 6  Original Android Development] Droidphilev:
Read. It works primary. I wrote you can swap so this should be clear i think. I also wrote this a page back.
[Nexus 6  Original Android Development] H4X0R46:
I have read back, read it a couple times actually, I tend to get confused sometimes however. On something you said in the page before, you said 6.0.1 would have to be in a secondary slot correct? And meaning the rom installed on system partition would have to be 6.0 on this case? Forgive me if I'm just confused again, this IS my first Nexus device, I came from a Samsung, WORLDS different lol
[Nexus 6  Original Android Development] Droidphilev:
You are mixing postings! Somebody aksed a way to have a full stock rom, that had nothing to do with 6.0.1
[Nexus 6  Original Android Development] deeplyyoung:
Guys have moved my primary existing Rom as secondary & flashed Cata 6.01 as primary then moved it as secondary & Flashed Chroma 6.01 as primary & everything is working smoothly...

just informing...:o

Late edit... As systemless root not working directly over secondary 6.01 Roms for me..
[Nexus 6  Original Android Development] Phrodini:
You're running a lite stock on secondary? I have 5.1.1 as secondary so I'm guessing I don't have to swap, just do a regular flash of whichever 6.0.1 rom of choice for primary.
[Nexus 6  Original Android Development] deeplyyoung:
It seems I'm not able to wrote correctly.. As of now or say with me, I'm (&few others too)not able to flash systemless root over 6.01 while trying as secondaries...have tried with Cata n Chroma as secondaries... Flashing screen freeze at flashing boot.img . that's why have moved my primary existing MM6 ROM as secondary cuz systemless root installing flawlessly over primary... Hope clear...

Edit: haven't tried lite yet..
[Nexus 6  Original Android Development] Phrodini:
I'm not worried about secondary, I have a lollipop rom on that. My primary is android M cata , I was clarifying that I should be good flashing over my primary without any issues. Thanks for the info.
[Nexus 6  Original Android Development] Gabbyii:
Encrypting Secondaries

So is it possible to encrypt secondary roms with or without the primary being encrypted?

Thanks
[Nexus 6  Original Android Development] H4X0R46:
I would guess no but I could be wrong, I have always left my Nexus 6 unencrypted because is truly yields much much better battery life, so I'm not too sure! I would guess no. I think the first page of this thread says something about secondaries asking to encrypt, and it says "do not do this!" In bold I think. But like I said, I've always just stayed unencrypted since I got this device!

[Nexus 6  Original Android Development] wrongway213:
Any source for unencrypted helping battery? First I have heard of this - as far as I know it is only supposed to boost read/write spreads, and many (myself included) think that is mostly placebo as well.. curious if there's any basis to this as I have never heard it before
[Nexus 6  Original Android Development] H4X0R46:
I've heard this before on multiple forums, it very well may be placebo, however, just the quicker read and write speeds do seem to have a noticeable effect with really heavy use! Like, moving huge files back and forth or playing heavy games and what not, not having to encrypt on the fly with no hardware for it seems to yield better battery. I think so lol

Sent from my Nexus 6
[Nexus 6  Original Android Development] wrongway213:
Ah, so it is the read-write speed boost that you (and apparently others) believe is tied to battery. That's a first for me, but I suppose it makes sense if you believe decryption really boosts performance. Either way, appreciate you explaining man.
[Nexus 6  Original Android Development] H4X0R46:
To each their own.

Also, since we're being politically correct in this thread, here's one of many sources where people are saying the same thing, found this with a simple Google search and about 10 seconds of my time.

[Nexus 6  Original Android Development] Droidphilev:
The first month i had a Nexus 6 i wasn't even aware that it was encrypted. I never saw any difference when i decrypted it (i only wnat to be able to access my data is someday something goes wrong while playing).
[Nexus 6  Original Android Development] moskvicheff:
Just wondering,

Has anybody yet got srated working on porting ubuntu touch to our device? :)
[Nexus 6  Original Android Development] githyanki:
Unfortunately, no. They have stopped supporting nexus devices at all and are focusing development on the ones they have partnerships with.

https://wiki.ubuntu.com/Touch/Devices

I really wanted to use this when I bought my Nexus 6.
[Nexus 6  Original Android Development] moskvicheff:
Yeah me too! I still do :)

My understanding is that they've not even participate any nexus 5 poring effort, however there's a version of ubuntu touch for this device. I'm wondering if it's still possible to port the ubuntu touch to a custom android powered device. Why not since they're running android kernel?
[Nexus 6  Original Android Development] githyanki:
Ubuntu is based on Android 4.4, and since there never was a 4.4 for the Nexus 6, there was no source for the kernel to be based on. That's the furthest I ever pursued the matter, I would be way out of my depth in trying to get a kernel working. The closest I had ever came to messing with kernel was make 'menuconfig;make clean; make install'. (Or something close...)
[Nexus 6  Original Android Development] Mayank97:
The link for the uninstaller is broken.

Aw that sucks, that would have been cool to mess with! :P
[Nexus 6  Original Android Development] 808phoneaddict:
Anyone know if this works app works with systemless root?

Was wondering if anyone had tried doing a full wipe, then doing systemless root, then installing multirom and going from there?
[Nexus 6  Original Android Development] amritanshu001:
I can confirm it does not work. I think its coz systemless root patches boot.img after install, so maybe the kexec hardboot patch is overwritten. I tried benzorom in secondary, which has system less root baked in, and ran into a lot of problems. Didnt have the courage to try it on primary :(

Edit: Maybe in primary, the kernel should be flashed AFTER the supersu 2.61. i dont know if there will be issues with system less root in primary then.
[Nexus 6  Original Android Development] adl:
I actually think it works on primary, but not on secondary. That's from what I read somewhere above. I think it was recommended to switch secondary and primary (so that the secondary is primary) to get it running for the secondary.
[Nexus 6  Original Android Development] deeplyyoung:
Doing the same procedure to flash systemless root, moving existing primary as secondary then flashing new ROM with systemless root as primary and then swap if needed...all works good...
[Nexus 6  Original Android Development] Droidphilev:
yes, i posted earlier if it works and how to do it. you should use a permissive kernel though.
[Nexus 6  Original Android Development] mkeller96:
Has anyone found a solution to installing 6.0.1 ROMs as a secondary? It fails every time when trying to flash as secondary.
[Nexus 6  Original Android Development] deeplyyoung:
Either try MR {unofficial} shared few posts above, or simply move primary Rom as secondary and flash fresh one as primary….
[Nexus 6  Original Android Development] mkeller96:
Can't find it

at 1st i thought that is was normal he didnt do updates staight away... but now im not sure, its like this guy fall from the face of earth.
[Nexus 6  Original Android Development] 808phoneaddict:
Hmm I missed this and glad someone brought it up, how do I flash this? In recovery (the IMG file for twrp multirom), I'm guessing this works well by those who's flashed this?
[Nexus 6  Original Android Development] Droidphilev:
You can flash an .img in your current twrp. Just choose "recovery" when flashing.

It works fine. One thing that's not working is flashing newer SuperSu builds (the ones that have systemless root) to secondary roms. If you don't need systemless root just use SuperSU 2.52 or if you do need this kind of root: flash the rom to primary and swap it to secondary if needed.
[Nexus 6  Original Android Development] greeneyez15o:
I tried swapping systemless rooted rom to secondary, but stuck on boot animation. I had to flash UnSu.zip in order for it to boot, n then i still had su privileges.
[Nexus 6  Original Android Development] Droidphilev:
It works fine for me after swapping. I think there's some other problem on your end. unsu.zip is only meant for systemroot, not systemless root.

quote from the maker of unsu:

"Note, to completely remove all traces of the systemless version, all you need to do is uninstall SuperSU, delete /data/su.img and flash a different boot.img, which is pretty cool and easy so I felt no need to add support for that."
[Nexus 6  Original Android Development] 808phoneaddict:
I tried flashing the IMG and the zip and both flashed successfully but when I tried to boot into my secondary rom I got into a bootloop and eventually booted into recovery...

I ran my primary rom and tried to boot to secondary through the multirom app and it didn't work either, same thing, stuck on Google image
[Nexus 6  Original Android Development] Droidphilev:
Far too less info!

-You flashed both the recovery and the zip from the androidfilehost link?

-after that you flashed a rom (+gapps if needed), a custom kernel and supersu 2.52 in twrp as a secondary rom?
[Nexus 6  Original Android Development] 808phoneaddict:
Oh no I already had a secondary rom that I had flashed on the official multirom,which has systemless and a custom kernel... Was hoping I could boot that secondary up
[Nexus 6  Original Android Development] Droidphilev:
I'm not sure if that will work. You mean you dirty flashed Multirom, right? I think you will need to start over.
[Nexus 6  Original Android Development] 808phoneaddict:
Yeah pretty much, well I overwrote the original multirom recovery with the modified unofficial one, I thought that should be alright, that's how wee do things in Android...

U mean I need to reflash the systemless rom in secondary with the modified unofficial multirom for it to work in secondary?
[Nexus 6  Original Android Development] Droidphilev:
as i wrote before: if you want systemless root in secondary, flash it as primary and swap to secondary
[Nexus 6  Original Android Development] 808phoneaddict:
I did do that but it won't boot up in secondary
[Nexus 6  Original Android Development] Droidphilev:
on a clean installed fixed multirom? no idea then, it works fine for me
[Nexus 6  Original Android Development] 808phoneaddict:
Oh I did that on the official multirom not the modified one, I'll give that a go

Edit: I flashed and swapped on the official multirom then when that didn't work I tried to boot it up with the modified multirom, and that didn't work
[Nexus 6  Original Android Development] Droidphilev:
you really need to start fresh!!!!

uninstall multirom

flash new multirom.

flash as primary

swap

!!!
[Nexus 6  Original Android Development] greeneyez15o:
Im gonna give this a try now cause i have the same issue. Systemless primary wont boot when swapped to secondary.
[Nexus 6  Original Android Development] 808phoneaddict:
Ok so I went totally clean (wanted to since I been crack flashing for awhile now), went back to stock then flashed twrp then modified multirom and flashed the zip also, then I flashed a custom ROM and everything seems to boot up fine...didnt try to boot and swap into secondary yet tho

But I did have a problem, I tried flashing xposed and when I do it boots but now I get nfc fc and some other fc (spool print or something) and I can't stop it from happening so I flash back to the rom to remove xposed and everything works fine now... Anyone have any ideas?
[Nexus 6  Original Android Development] 808phoneaddict:
Also, using the modified multirom, I can no longer use the multirom manager app correct?
[Nexus 6  Original Android Development] demlv:
You can use it to boot/switch between ROMs. You just need to be aware that it will show that updates are available (the standard multirom stuff)....so you should not choose to apply updates through the app unless you want to go back to the older (standard) multirom.
[Nexus 6  Original Android Development] 808phoneaddict:
Ok I tried booting up the systemless rom that I installed on primary then swapped to secondary and it did boot up! Woo-hoo! Nice work!

PS sorry for the numerous posts lately!
[Nexus 6  Original Android Development] greeneyez15o:
Did it take a long time to boot up at 1st ?
[Nexus 6  Original Android Development] 808phoneaddict:
No actually, booted up like regular

Edit : actually I do recall it booting up on first run and going to the multirom rom select page then rebooting and going back to it, then followed by it booting up correctly
[Nexus 6  Original Android Development] greeneyez15o:
Does using the original multirom cause issues , with the new development ? Ive updated n had a couple problems with backingup, restoring, flashing, etc. So i ended up going back to original.
[Nexus 6  Original Android Development] Droidphilev:
Yes. You will get problems with M roms. I never had problems with backing up, restoring etc
[Nexus 6  Original Android Development] greeneyez15o:
To update should i flash multirom uninstaller, amd then flash the new mod. Or just flash the mod over existing multiromtwrp ?
[Nexus 6  Original Android Development] deeplyyoung:
Best option is to use uninstaller then start from scratch....:o
[Nexus 6  Original Android Development] greeneyez15o:
What version of systemless root can i flash over a secondary rom ?
[Nexus 6  Original Android Development] deeplyyoung:
Systemless Root Not gonna Work over secondaries Roms, just swap them with Primary & flash SU
[Nexus 6  Original Android Development] 808phoneaddict:
With the modified multirom posted earlier, they run if you flash them primary then swap them to secondary
[Nexus 6  Original Android Development] deeplyyoung:
I want to say that you can't flash systemless su directly over secondaries ROM you need to swap with primary and after flashing Systemless can reswap... Haven't tried modified one yet..
[Nexus 6  Original Android Development] amanker:
I am using Cataclysm latest stable android 6.0.1 with systemless root. I want to install android 5.1.1 as secondary rom.

I tried official and unofficial multirom.

Many different 5.1.1 ROMs.

Changed lernels also.

But never got success in 5.1.1 as secondary rom.

Everytime either it stuck on google logo and reboot.

Or if 5.1.1 start booting then boot never complete whatever time i wait. It never completes to home screen.

Please help.
[Nexus 6  Original Android Development] demlv:
You can backup Cataclysm, install stock 5.1.1 as primary, restore Cata as secondary, then set Multirom to autoboot the secondary. Not exactly what you asked for, but it will work. Any particular reason why you want 5.1.1 installed as secondary?
[Nexus 6  Original Android Development] amanker:
Yes.

I am using xmodgames. For playing coc.

And xmodgames dont work on marshmallow
[Nexus 6  Original Android Development] demlv:
I truly don't understand. With multirom You can boot a lollipop rom (installed as a primary or a secondary) anytime you like and use xmodgames, right?
[Nexus 6  Original Android Development] amanker:
This was answer to your query, why I want Android 5.1.1?

No, I couldn't install 5.1.1 rom as secondary rom. As mentioned in my previous post

.
[Nexus 6  Original Android Development] Droidphilev:
Flashed Blisspop (5.1.1) as secondary yesterday. I use CataMod as primary. flashing (using SuperSU 2.52) and booting works just fine.
[Nexus 6  Original Android Development] amanker:
I tried bliss pop also.

But boot never completed.

I changed kernel to zen kernel.

Same result

I have cataclysm with system less root supersu 2.64

Installed official and unofficial multirom.

I have cache and data partition formatted as f2fs

Tried different 5.1.1 roms never flashed supersu or gapps on secondary rom.

Secondary rom never completed its boot

Can you elaborate what roms and procedure you used please
[Nexus 6  Original Android Development] Droidphilev:
Primary: Tupac4u lite rom, CataMod, ElementalX (permissive), SSU 2.52 (so no systemless root), Xposed framework

Secondary: latest BlissPop, Elite kernel, Opengapps, SSU 2.52, Xposed framework
[Nexus 6  Original Android Development] demlv:
My point was that even if you cannot successfully install a 5.1.1. rom as secondary, you can still simultaneously run a 5.1.1 rom and a 6.0.1 rom, so long as you use the 5.1.1 as primary, and the 6.0.1 rom as secondary.
[Nexus 6  Original Android Development] Droidphilev:
I'm using it the other way around. M as primary, L as secondary. Works fine here.
[Nexus 6  Original Android Development] deeplyyoung:
With system root have used plenty of Roms either primary or secondary without any issues except few which can't be flash as secondaries (like AOSiP)... Cata, Chroma, PN,aicp,Blisspop,DU...all working without any issues..but with system root.... Just for info...
[Nexus 6  Original Android Development] vsot13:
Scratch DU, they went systemless root. So no secondary
[Nexus 6  Original Android Development] deeplyyoung:
Rite now my primary is DU...
[Nexus 6  Original Android Development] vsot13:
You can installed as primary and swap it, but you can't installed as secondary

[Nexus 6  Original Android Development] 808phoneaddict:
As long as you have enough space to swap roms, as long as you install on primary then swap it, and use the modified multirom, then u can have as many systemless roms as you want
[Nexus 6  Original Android Development] demlv:
Do you truly need to swap ROMs to do this? Couldn't one choose to install a systemless ROM as primary, back it up, then restore it to a secondary slot?
[Nexus 6  Original Android Development] spiral777:
n6

yea ive got enough room...64gb nexus 6 (55gb to play with)

how did you go about it? i dont get what you mean by swapping if i can only install a systemless root rom as a primary rom...

and where can i find this modified multirom?

thnx again
