How does backup work? Can i create a nandroid of both roms?

I´m running this now with RR as primary and CM as secondary for a nice test. It works but how can i install gapps, su in the second rom? Touch doesn´t work on those roms so i need to set auto boot in recovery first.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] lindahl85:
I found one issue. Just like when restoring a nandroid backup, the pin pattern becomes wrong when i shift from primary to secondary and back to primary again.

I only delete "gatekeeper.pattern.key" to access my phone again.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BitOBSessiOn:
Go to MultiROM options (upper right icon), List ROMs, select ROM, and there you can install any zip (gapps, su, etc...).

It doesn´t :) Is it possible to use the nethunter kernel on my secondary rom? (CM13)
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] xanthrax:
I haven't tried but most probably yes, the multirom uses the ROM kernel to boot not a kexec patch, try and report back, you can always erase the ROM and it won't affect the primary ROM

Sent from my Darkside of Oneplus 3T
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] lindahl85:
Will do :)

EDIT:

Tried now with cm13 installed. After that, reboot to recovery and flash:

nethunter-generic-arm64-kalifs-full-rolling-3.15.3-20161205-0246

then

kernel-nethunter-oneplus3t-marshmallow-3.15.3-20161205-0246

It boots, then bootloop, start multirom menu so i can see cm13, then it goes totally black and turn off itself.

TWRP 3.0.4 is out. I guess the MultiROM version will be updated soon to.

Should I wait until I try this out, or I should go for it? I'm on OOS 4.0.2 and would like to have LineageOS as my second ROM.

I would suggest to wait for a few days... F2FS is not working as expected... Although it works, we are getting too long TWRP booting times because FS checking, etc...

I've moved my /data partition to encrypted EXT4 for testing.

I hope we can enjoy latest TWRP-MultiROM soon... but no ETA, facing also some theme issues because theme engine has changed in 3.0.4.

[MENTION=6411851]BitOBSessiOn[/MENTION] BUG REPORT (Oneplus 3 build, not 3T): i am not able to install secondary roms with your latest mrom-TWRP build for oneplus 3. It was working on build-006 (although, for some reasons, i had to delete locksettings.db everytime i flashed a secondary ROM because it did something (?) to the password).

With the latest 3.0.3-1 build (didn't try in-between ones) it gives errors like "unable to update system.IMG" or something like that, unless i flash the current ROM as secondary too, wich succeeds;

I'm installing them on Data partition with F2FS filesystem (could that ne the problem?)
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] rkn989:
the white LED issue is with the OOS 3.5.1 version as I can see. After dirty flashing with OOS 4.0.2 and then flashing mtwrp rom works fine. Strange .... :mad:

I din't get the exact steps here. I was trying to decrypt the device - went into fastboot mode and format userdata - when logged back into twrp - the memory was just 24 gb :(

Can you let me know how you fixed it?

You just have to do a "Factory Reset" in TWRP menu (Wipe).

It should, but only tested on op3t. Waiting for feedback from any op3 owner...
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] knpk13:
Yay, new update!

Does it have all the fixes from 3.0.4-1? Also which Roms did you test? Do Roms with the new and old f2fs work fine with multirom? I still don't understand this new and old f2fs thing, it'd be helpful if someone could explain it in detail.

I'm assuming the old multirom uninstaller still works with this?

I asked this before, and xanthrax gave me an answer.. but can you confirm that any zips (that contain firmware) installed as secondary Roms won't overwrite the actual firmware of the device? Like for example if I flash OOS 4.0.2 as secondary (or a custom rom that ships with firmware), it won't overwrite my primary OOS 4.0.3 firmware?

Edit: MultiROM working with OOS 4.0.3, Lineage, Omni, and Slim so far.

[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] deeplyyoung:
I still using ext4, as no reason have found to change type to f2fs, rest latest version is working just perfect. Whereas your query regarding FW, yes if you flash ROM containing FW or you flash FW over secondary it will overwrite your device FW and modem,as it's not ROM based.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BIGWORM:
I'm pretty much gonna test this combination, except FreedomOS 1.3 will be secondary (based on OOS 4.0.3). Wish me luck!

*edit* Yeah, that didn't work lol. I'm on RR right now and for some reason Freedom OS is failing to install as primary. Something about gapps contained in the zip is incompatible. Even freedomOS 1.2 is giving me the same error, now. Hmmmmmm. I'll flash the full ota then see if freedom will dirty flash over that. Will update shortly.

*Edit 2* So, got stock oos 4.0.3 to boot as primary with RR 5.8.1 as secondary. RR keeps telling me that SuperSU needs to be updated, though i flashed the separate zip, the systemless flash. I'm guessing that may have something to do with the conflict. I guess I could uninstall it and use the built in root solution Privacy Guard. I'm not sure if the non-systemless SU will work. I've been using SR3 2.79 since I've had this phone the past month or so. If I install multiple zips on the primary ROM, including the ROM itself, should I uncheck install multirom after complete even when I've already installed it? I'm ultimately wanting to room freedom os as primary then RR as secondary, if that's possible.

So, getting "failed to mount trampoline" errors when trying to flash RR official as secondary. Op, did you want me to try again and dump a logcat?
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BIGWORM:
Had to double post to attach log. I'm guessing it has something to do with the 4.0.3 firmware. Can I pull the modified boot image from the system partition then mount it?

*edit* got it working running oos 4.0.3 and latest RR official. I had to reinstall multirom, flash RR as secondary, run restorecon, deleted secondary, then reinstall RR again. I will note I'm not seeing SuperSU at all now on RR, even flashing it. Again, its probably because I'm flashing the systemless version. What exactly does restorecon do? I ran that combing over this thread, lol!

[MENTION=6411851]BitOBSessiOn[/MENTION]

I bricked and unbricked my phone four times today to identify the problem.

The problem started when i flashed unified multirom twrp and zip

--> This allowed me to flash oneplus3 roms on oneplus3t device which is resulting in brick.

ro.build.product is still oneplus3 in oneplus3t device which is causing this problem.

However the earlier builds on multirom had ro.build.product=oneplus3t

Later I had to downgrade multirom to

twrp:

TWRP_3.0.3-2_multirom_oneplus3t_20170128-02

multirom:

multirom-20170128-v33-UNOFFICIAL-oneplus3t

This is working for me.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BitOBSessiOn:
You must flash only unified OnePlus 3 ROMs or specific OnePlus3T ones. If flashed ROM is only for OnePlus 3 (not unified), yes... sure you get a brick...

Can you confirm this approach, please ?

If we want to unify 3 and 3T worlds, it seems logic that we must identify both models simply as 3... right ?

Thx.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] ram4ufriends:
Can we change the version name to 3.0.4 to be consistent with Official twrp version you are using?
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] raj7749:
Yes it is absolutely logical to unify 3/3t as 3, this also helps developer in many ways. However if any rom which is not unified is flashed over the other device could cause brick.

We have to be careful now for what we are flashing in secondary rom to avoid brick.

(Using unified recovery) Flashing:

1. oneplus3 over oneplus3t device is possible --RESULTING BRICK

2. oneplus3t over oneplus3 device is not possible -- AVOIDS BRICK

This kinda gives oneplus3 an upper hand to avoid such situations.

Just wanted to convey the message.

However nothing is going stop me from flashing unified builds over my 3t. :D

Thanks a lot for you efforts :good:

[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BIGWORM:
Nope, its the right twrp. Need the commits from that recovery to flash stock OOS 4.0.3, which i did, as primary. In addition to that, I had latest RR official installed as secondary. You need to update the firmware on your phone. You're more than likely getting a TZ mismatch.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] lindahl85:
I noticed that i was only on 4.0.2. It worked after that but there is some issue when i try to boot my primary rom. I get the boot logo as usual, apps starting, then it goes to the multirom menu and restarts. The fix seems to be to reflash the multirom zip again.

EDIT: That didn´t help either. It seems like 4.0.3 can´t run Marshmallow. I jump back to 4.0.2.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BIGWORM:
Yeah, if your primary rom is 4.0.3, your secondary is going to have be based off of that same firmware, I believe.
