Actually, after a reboot it started to work... Same as for rr rom and miui (shame on me, I don't like miui [emoji4])

The video error is caused by a third-party camera application, this happened several times previously but this time I haven't used any, only the one from the rom, very weird, Oneplus is really joking about this camera, no blobs and no support, secretomania at its best

What is making a secondary ROM boot or not?

With OOS 3.x.x, I was flashing another kernel in primary rom for roms that I couldn't boot as secondary, but not a single kernel was able to boot all kind of roms, some with elemental, some with boeffla and etc.

Now updated to OOS 4.0.1 (finally!) with the stock kernel I can boot on cirtus or lineage for example but not resurrection (neither official or unofficial) while with OOS 3.x.x and stock kernel, i could boot on unofficial RR but not the official, with custom kernel could boot on both.

Every time I flash full zip ota 4.0.1, it happens after the first restart.

I tried it once, worked perfectly but the kernel didn't support multi ROM so the touch screen wasn't working when choosing ROM at boot^^

Will this be incorporating the fixes from the official TWRP for OP3T?
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BitOBSessiOn:
Yes, it will.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] raj7749:
first u will need to decrypt the device storage.

use following command to decrypt

fastboot format userdata

then install latest twrp from fastboot

fastboot flash recovery twrp

then boot twrp

fastboot boot twrp

then install the latest multirom recovery image file from twrp, this will replace twrp..

reboot again to recovery

install latest multirom zip.. good to go further on
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] raj7749:

Is it ok to flash over existing multirom?

Does this have the f2fs backport drivers?

And [MENTION=7896746]koenkk[/MENTION] , will this recovery work with your LAOS ROM flashed as a secondary ROM, since you recommend the TWRP version with the f2fs backport.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] koenkk:
No my ROM does not contain the backport f2fs. I changed my recommendations to the latest TWRP available.

Hi guys!

First of all thanks for your awesome work, I would like to install MultiRom on my OP3T but I still have some doubt about the installation process.

I already have the TWRP standard version installed (not TWRP-MROM) and according to this unlocked bootloader. From what I understand all I have to do is:

- Flash TWRP-MROM modded and reboot in recovery mode (you need to unlock bootloader, etc...)

I saw that the TWRP-MROM is an .img file. Can I flash it from the "Install" section of my TWRP standard recovery?

- Flash MultiROM ZIP

Nothing to add, perfectly clear

-Set No-Kexec option in settings for MultiROM from TWRP

-Inject boot sector

Are this two options that I will found directly once I have flashed the TWRP-MROM recovery or they should be present also on the standard TWRP recovery?

- Flash your favorite ROM as secondary from MultiROM menu (Add ROM...)

- Reboot

-Select ROM to boot from MultiROM menu

Sorry for my questions, still my first steps here :) ... and really thanks for the provided help ;)
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] nadejo:
You can flash it in recovery. After pressing on install zip you can choose install image at the lower right side then install it as recovery
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Stefa.:
Thank you for this ;)

What about the

instead? Are this two options that I will found directly once I have flashed the TWRP-MROM recovery and I ahve to "enable" them after the MultiRom installation or they should be present also on the standard TWRP recovery?
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] nadejo:

[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] bird333:
You don't have to do those. I think the No-Kexec option is already set so if it is not you might have to check that box.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] raj7749:
It is available after flashing modded twrp and also it is enabled by default but still confirm the same if its enabled

[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] rkn989:
How did you fix this issue??? I'm having the same issue even after flashing all the versions of Mrom and normal twrp
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BitOBSessiOn:
Fastest way to get decrypted from a pure stock scenario:

1. In fastboot mode, after unlock bootloader:

>fastboot flash recovery TWRP.img (MultiROM version if you wanna....)

>fastboot format userdata

2. Boot into TWRP (DONT'T reboot system, go directly to TWRP from fastboot mode):

>flash SuperSU-2.79.zip

Now you can safely boot system, you must be rooted and decrypted, you can back to TWRP, flash MultiROM.zip, set bootsector and no-kexec in advanced otions and play around...
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] rkn989:
Thanks for your reply ... but the issue I have is with after flashing twrp. Once I flash TWRP from fastboot, and boot back into recovery it just goes to a black screen with the white LED ... [MENTION=3634934]lindahl85[/MENTION] had mentioned that issue before .... so wanted to know how was that fixed???
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BitOBSessiOn:
I had something similar with my previous OP3... Have you tried to do all the "unbrick" process to re-flash all-stock system...? And then try again with TWRP, etc...
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Stefa.:
Thank you guys!

Today I successfully installed MultiRom, nice work ;)
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] rkn989:
Yes I have tried that multiple times. Read in some other post that it's an issue with OOS 3.5.1. Any way to get the unbrick tool updated to OOS 3.5.3 or the latest OOS
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] HTCore:
I took these steps to solve the issue, IF you don't mind to lose your data;

flash twrp (not twrp-mrom)

twrp > advanced wipe everything

fastboot format userdata (...used to do this before but the last time I tried without three earlier steps it didn't work, still got black screen w/white LED!)

flash stock recovery

flash full oos

reboot the bootloader directly (don't boot to oos)

flash twrp

reboot to twrp (don't boot to oos) and flash supersu

reboot to bootloader again and flash twrp-mrom

flash mrom zip

enjoy mrom and do whatever you want!

Edit 1:

NEVERMIND! The black screen w/white LED again! I did all the above last night and was fine before turning the phone off, just turned on to play with, it DID happen again... can't find the logic!

Edit 2:

Flashed back twrp, worked fine, flashed twrp-mrom, black screen w/white LED, did this 3 times same result everytime.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BitOBSessiOn:
Weird... I only can try to build a twrp-mrom version based on latest clean official twrp source code... and check again...
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] bird333:
I'm still on 3.0.2.0, but where is the 'set bootsector' option? I don't see it.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BitOBSessiOn:
It's one of main options (buttons) when you go into MultiROM menu in TWRP (Inject bootsector).

You can also update to 3.0.3-1.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] bird333:
Ok I was looking for some kind of 'checkbox' under settings. BTW, do you actually have to do that (Inject bootsector) before or after you install a rom? I don't recall doing that when I installed RR as a secondary.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BitOBSessiOn:
You need to do it only once after installing MultiRoM.zip
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] HTCore:
It's really strange and some sort of random, i can't figure out what cause it or when starts to happen. Some steps that I take to fix it, works for one day but not for another and vise versa. Now, I made it working by flashing stock recovery back, then twrp 3.0.3-1 and then MROM... same thing didn't work for the other time.

Completely unrelated, one thing thing I noticed; after every clean installation of OOS (decrypt, full ota and etc...), as soon as I flash MROM the screen size changes to smaller size in OOS, I remember a user also reported it while ago and he settled with changing Settings > Display > Display Size option. I am doing the same and not a deal breaker at all but I'm just curious why. Can you check that too please?

First two screenshots are before flashing mrom and the other two after.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] michelD:
Hi,

Sorry if I didn't read the complete thread, but a research give me no result.

I flashed everything as explained. It was perfectly working until I brick my phone (after flashing a test build RR_5.8.0 18/1) and I had to unbrick using the MSM method.

Then I am trying now to install multirom again but it fails when I try to root OOS4.0.2 with SuperSu 2.79, I have the following message "failed to load bootimg!"

And then when I reboot, I don't have the multichoice screen: it directly boot to my internal ROM (=RR_5.8.0 stable 11/1).

Moreover, in the list of ROM in TWRP, it only list the secondary (OOS4.0.2) and not the internal.

I probably forgot something, but I don't know what ?

Thanks in advance for any help
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] HTCore:
Did you decrypt your phone?
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] michelD:
Indeed, you seem right, I never realise my primary ROM RR5.8.0 was encrypted, even if I never ask for it nor configure any pin or fingerprint, and TWRP never asked for a password !

Now I'll try to decrypt...

Edit:

after decryption with the toolkit, my internal memory = 24.8GB instead of 128 GB !!
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] abhisek1994:
You have to format device when you go to wipe option in TWRP it from TWRP and it will go back to it being 128 gb(more like 113 but you get my point)
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] michelD:

I reflash AICP ROM in primary and OOS4.02 in secondary and everything seems OK now !

Hi guys!

I have the stock Oxygen OS 3.5.4 (Marshmellow) as primary ROM.

Is it safe to flash a Nougat ROM as secondary? It's also safe the ROM switching considering that the primary ROM is Marshmellow and the secondary ROM is Nougat?

Thanks a lot for your answers ;)
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] michelD:
Edit 2:

the problem I have now is that the multichoice panel is not touch sensitive !?! So it is impossible to select the ROM except via multirom TWRP

Any suggestion ?

Thanks
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] bird333:
Thanks. Couple of quick questions. What is 'Run Restorecon'? It that for restoring the backup? What does 'Inject boot.img' do? What's it's purpose?
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BitOBSessiOn:
Don't your buttons work? Which kernel do you have on your primary...?
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] BitOBSessiOn:
Dunno atm about restorecon, sorry. Inject boot.img simply flash a boot.img file from your election.
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] michelD:
Yes indeed, the multi choice screen appears, but the buttons do not work.

I am curently using AICP ROM v20/1/2017 as primary.

Anyway, I'll try another one

The other problem is that I am still unable to root the secondary (=OOS4.0.2): when flashing Supersu 2.79 SR3, I always have the error message : "failed to load bootimg!"

What can I do?

Thanks for your help
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] acuicultor:
Restorecon is intended to be used in order to fix permissions issues and/or selinux related issues, Inject boot.img just Inject the kernel in primary rom into multirom afaik that's just needed in older mrom versions without the no kexec workaround.

You need a compatible kernel in primary rom to get touchscreen working in multiboot menu and for root in secondaries try with stable supersu 2.79 it works flawlessly here.

Thank you, indeed, I now flashed RR_5.8.0 official dated Jan,21 and I finally get rid of the "failed to load bootimg!" when flashing SuperSu.

But I still have the issue of non responding touch screen with the Multi-choice screen. but not a big deal, I can change booting ROM via multirom TWRP.

If I understand correctly, it is an issue related to the kernel of the primary ROM. Correct ?

Thanks again for your help
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] bird333:
Ok, well then how do you restore a backup from multirom? Because that one button was the only on that has 'restore' in the name.

[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] xanthrax:
Yes, you can flash nougat as secondary, to be safe, remove any security lockscreen before

I don't really understand what people means by "switching", if they mean replacing the secondary with the primary, that's swapping, by switching I understand, moving from a rom to another and if this is what you mean then, that's pretty possible

I haven't tried swapping the roms but I'm afraid that isn't safe, twrp isn't fully stable as off yet

Actually, this swapping doesn't make too much sense to me, you can flash everything on a secondary rom, the only thing isn't possible for the second rom, OTA but, how many roms with a working ota we have and moreover, how safe is it to flash ota a custom rom?...

Sorry for the misunderstanding, by "switching" I mean moving from a ROM to another as you stated.

Thanks also for the information on the swapping. The impossibility of receiving an OTA update is not a problem at all considering that it's a custom ROM as you rightly stated ;)
[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] michelD:
OK thanks

The problem I have now (and that I didn't had before bricking/unbricking is, after successfully fash RR_5.8.0 as primary and OOS4.0.2 as secondary, is the following: when I boot with one ROM, it totally wipe the Data partition of the other one, even WITHOUT encryption on any of both ROM.

Moreover, now in TWRP, the "sdcard" partition appears empty while I can see the content when ROM is booted.

I suspect that the MSM unbrick program when pushing OOS3.5.1 change also something very deep in the hidden partitions related to encryption process.

My "fault" was probable to directly flash multirom TWRP 3.0.3-1 and then only the OOS3.5.4 boot.img and not having done a full factory updating to OOS3.5.4 before.

What do you think?

Thanks
