After several failed attempts as well, I finally managed to start Syberia as second rom only reinstalling (and flashing the rom from) the previous build of Multirom (20181118); remember that this buid has a bug with the brightness: you have to set it at maximum level (just once) in order to be able to see the boot menu; despite this, I assume that this bugged/older build has more rom-compatibility than the newest one.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Shahan_mik3:
That is not possible from our end too many roms..maybe some user can do it

I have tested below ROM

Miui beta

Miui eu

Miui globe

Miui pro

Nos

Los

Aosip

Pe

Benzo GSI

Mtp is disabled (adb push file) and vib also needs to be added

[MENTION=6282592]ydd0ras[/MENTION] if m not wrong has flashed almost all roms without any problem
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] ydd0ras:
Yes, [MENTION=5162591]Shahan_mik3[/MENTION] you're right. I have tried nearly every available ROM (the ines you have mentioned + Bliss, Bootleggers, Citrus...) including 2 gsi. Never had a single issue with Syberia, regardless wether LOS or MIUI was on internal. Flashed Syberia last night once again; everything is fine.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] zedbest:
This is not a competition between who is right and who is wrong: impossibility to install Syberia for some users with the last Multirom is just a matter of fact.

Please have respect of other else experiences and try to give solutions: the way I did after I found my personal workaround (after all, I advised the same tool of the same developer who I give all my gratitude).

Any tip helps more than a screenshot and we are here to help each other. Thanks.

That' s exactly what i always do. Just replace the multirom and recovery files with the latest. Flash always the latest vendor/firmware zip.

That's my procedure - always and with every ROM.

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] -TheKoolAnie-:
Same problem, Can not able to boot Los as secondary ROM .
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] colossus_r:
I Had the same problem with those roms as I posted in previous Page.

I deside after all those tries to install PE and LOS to start from scratch.

So I format everything even internal and start installing roms. And all of the sadden all roms that I try was installing fine with no problems.

What I did :

After formating everything I first installed miui eu 8.12.20 as primary as usual.

Then multirom 18112018 and multirom twrp.

Then Pixel experience latest

Then Los latest

Then Reloaded CAF

Then Syberia.

And PixelDust, msm xtended and Nitrogen.

ALL OF THEM where installed and working good.

Procedure to install secondary roms

1. Add new rom with default settings and select install zip.

2. Install the latest firmware and vendor zip. (8.12.20)

3. Install rom zip

4. Install DFE (encryption) zip with magisk 18.0

5. Install open gaps Nano 21122018.

6. Reinstall DFE again as a safety (some times not working the first time)

Now boot your rom (wait some times needs 5-10 Min)

DONT SET PASSWORD OR SECURITY ON SECONDARY ROMS. IF YOU DO YOU WILL NOT BE ABLE TO LOGIN TO YOUR PRIMARY ROM.

I hope this post will help people to install any rom they like.

One small query, I am currently on Miui 10, unlocked, rooted with magisk but encrypted. The twrp I use supports encryption and everything is working fine

Can I install multirom keeping my encryption intact with multiple roms ? I have lot of dual apps not contents in phone which I don't want to lose
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] k@iserex:
You can use multirom on encrypted data without issues but as I have understood you can't have password/PIN/lock whatever security measures you have on both ROMs ( primary, secondary, third and so on...), so if you have that on your primary ROM and set up the same thing on secondary you'll be locked out of your primary ROM, so it is what it is.

I'm on a clean flashed Bootleggers 4.0 rom with Magisk and TWRP 20181012. i install MultiRom.zip thru Recovery, boot again to recovery to flash MultiRecovery.Image, but then when i do a reboot in recovery it wants a password.

Hello all,

i have several questions about backups and rom switches between internal and secondary.

1. Can I move roms from secondary to internal (other way I test it works, but if I copy the secondary to internal it will not boot (boot loop)

2. can I create Backups of Secondary and the install as internal or install witout multirom.zip

3. can I create Backups of Secondary and install as new secondary (use System.image Vendor.image boot and Data I get an error and it will not be installed) if I make this with an Backup from internal it will works

4. Must I use the system.image, vendor.image for Backup, I make yesterday a mistake with the internal (backup only system, vendor, boot, dat without .image) and I can install this as secondary and it works

I will test more with Backup and restore to secondary, but for internal it is tricky one mistake and I must install all things new.

Thanks for helping

Edit:

to 3. the Error is this: Prozess mount -o loop.noatime.ro -t Auto "path of the backup" /System_image.emmc.win" /tmp/System endet mit Fehler: 1 (ending with error Code: 1)

if i make the Backup on secondary not with .Image then it is working.
