[Nexus 7 Original Development] jp007_uk:
I have a Samsung Galaxy S4 GT-I9505 with Albe95’s Lollirom v6.0 which has the Imperium v2.6 kernel.

I successfully installed the Multirom app from Google Play, which has installed the following:

Multirom:	v32b

Recovery:	2015-10-29 (0)

Kernel:	has kexec-hardboot path (in green)

I have successfully installed an additional ROM through the recovery but I can’t boot into the secondary ROM. When I boot back to the above primary ROM the Kernel patch is in red.

Extra ROM’s tried: Albe95 ASTRA v2 Note 5 PORT and Aurora S6 Port 5.2

I have tried installing other kernel patches from post #32 but then the primary ROM fails to boot and so I have to re-flash the primary ROM.

Can anyone advise?
[Nexus 7 Original Development] bilbonotry:
I cannot help you with multirom, but there is another tool for s4 called dual boot patcher which does not need a specific kernel
[Nexus 7 Original Development] paolocorpo:
I am surprised about the release of multirom ... Is it 32b ???:confused:
[Nexus 7 Original Development] jp007_uk:
Yes 32b
[Nexus 7 Original Development] paolocorpo:
On OP i cannot found the link for this new version

Can you help me ?

TKS so much
[Nexus 7 Original Development] jp007_uk:
All I did was go to Google Play and download the latest MultiRom app and then open the app and click install, this will install the latest version which my case was 32b.

However I have not managed to get this working with TW ROM as primary and TW or CM as secondary. My phone is the international Qualcomm based gt-i9505.
[Nexus 7 Original Development] paolocorpo:
Probably it depends from device

I have a N7 2012 3G and you ?
[Nexus 7 Original Development] Thomas_xxxxx:
So just download MultiROM Manager, install v32b and I will have working multirom on Nexus 7 2012?
[Nexus 7 Original Development] paolocorpo:
NO, you have to apply what is suggested into first post of this thread

For instance you have to youse a dedicated recovery custom and a dedicated kernel

Some roms "check" if you have installed multirom or some other mods and dont install if you have done so. Your only choise is to remove the checking part of the code from updater.sricp
[Nexus 7 Original Development] badhon_raj:
Thanks a lot.

I was able to flash the rom successfully.

For reference, I removed two if blocks from the script.

btw, would you know where I can get help about flashing nethunter?

The installation gets stuck at the last step.

When it says "installation finished" I click next and it stops responding until force reboot.

By the way how could you even install multirom because I have also blisspop and always when I am trying to install multirom I get a bootloop?
[Nexus 7 Original Development] badhon_raj:
Apparently, this is wrong section for me since I'm using 2013 nexus 7.

I was supposed to post in that section but some how made the mistake.

Anyway, if you are using 2013 nexus 7 too, then use the updated multirom zip from here:

http://xdaforums.com/showpost.php?p=64875448&postcount=1248

It worked without any problem for me.

Btw, if you flash the zip downloaded from multirom app, then it won't work on marshmallow

Guys, I need some help.

So, I installed ElementalX-N7-5.07 kernel.

Then I opened the MultiROM app on my rooted stock 6.0.1 Nexus 7 2013 FLO and installed MultiROM.

When it booted into the MultiROM boot menu I picked Reboot Recovery.

Went to Advanced->MultiROM->Add ROM.

Chose the DirtyUnicorn 5.1.1 ROM and installed the pico gapps.

Booted DirtyUnicorn, all was fine.

Tried to boot back into the Marshmallow internal ROM, it just sent me back to Recovery.

Tried to reinstall supersu and then the kernel again, restarted tablet, chose Internal ROM, booted again back to recovery.

Tried restoring the nandroid backup I did just before I installed the kernel. It says:

Restoring System...

and 10 seconds afterwards:

E:extractTarFork() process ended with ERROR=255

But installing the ROM in MultiROM from backup works fine but it still doesn't boot, still sends me to Recovery.

Also, recovery keeps asking me to install SuperSU because it "does not appear to be rooted" but I keep saying "Do Not Install" every time. Not sure if relevant or not.

Anyone have any idea what I should do to boot into my internal ROM?

EDIT: Fixed it by flashing https://www.androidfilehost.com/?fid=24269982086994463

bodhi and cm12 dual boot

I used the link http://jeffhoogland.blogspot.sk/2012/12/bodhi-armhf-alpha-for-nexus-7.html?m=1 to install the bodhi.

However i have problems running it together. I did as you wrote. First install bodhi following strictly instructions from the link. Bhodi installs and works nicely.

Then I use TWRP to install CM12, by using "ADD ROM", not with INSTALL.

By that point it looks good. Still booting linux by default. Then I make the CM primary, it loads, but the linux does not anymore.

What am i doing wrong?

Should bhodi be installed strictly like in the link, as... I don't know where it installs it but after installation it shows that internal memory is arount 6 GB (normally 13.5 GB). Shouldn't these ROMs be installed in /sdcard... from what i have read..?
[Nexus 7 Original Development] MupEHcEH:
Thank you all, for not replying to my posts in this great forum full or nice and helpful folks.

This post is for people like me who have struggles making that multirom stuff to work - i just used older versions of TWRP, multirom and did the same thing as before. If it does not work for you just try with not the latest stuff.

I personally used TWRP_multirom_grouper_20140914.img, multirom v30 with trapmpoline v14, primary OS CM11 with kernel_kexec_grouper_cm11.zip and now i have installed 2 versions of ubuntu touch preview, plasma, bodhi + the CM11.

Once again! THANK YOU!

[Nexus 7 Original Development] bilbonotry:
Weird, I have updated to latest multirom with twrp 3, had before cm11 and cm12, then installed bodhi by classical install (twrp > install > bodhi.zip) and it worked. Had your kind of error when I tried to add ROM in multirom submenu.

This is an invaluable addition to android arsenal, and I love it!

I have a problem though, my boot menu stopped working and injecting the boot.img isn't helping in that aspect.

Anyone have an idea on how I can fix this?

Thanks.
[Nexus 7 Original Development] MupEHcEH:
Hey, so what exactly do you mean? Do you even get the menu or it just boots the default (intenal) ROM without showing and asking you for ROM?
[Nexus 7 Original Development] Merchantman:
Thanks for the reply

Yes, just boots directly into my main rom without letting me choose roms.

And manually choosing to boot to the secondary rom from recovery multibot doesn't seem to be doing much because it still just boots to main rom.
[Nexus 7 Original Development] MupEHcEH:
Happened to me once I updated my internal ROM. You can try to restore if you have back-up. Or maybe someone else here can help you.
[Nexus 7 Original Development] Merchantman:
Well, I'm at a loss.

I've completely formatted the device, and reinstalled everything from scratch like the numerous tutorials say however, I still don't get the boot menu while starting the device.

[Nexus 7 Original Development] jbaumert:
Just curious, did you check the boot settings in MultiROM (via TWRP)? There are settings for auto boot / show menu / etc.
[Nexus 7 Original Development] Merchantman:
Update: after I thought it was fixed, while I did get the boot menu my Marshmallow main rom wouldn't boot (black screen) humph...

[MENTION=4681892]jbaumert[/MENTION]: Yes I have, it's set to 5 sec delay on boot to let me choose - thanks for the tip though.
[Nexus 7 Original Development] MupEHcEH:
That's strange. I did the 'boss' thing as well :) and it worked for me. What boot.img do you use? Also... if you have read my recent posts when I wipe my device at first I use old versions of TWRP and multirom in order to be able to install linux distros, then I upgrade to I can install CM12.1 or later. Otherwise it does not work for me the linux install.

Have you used the marshmallow kernel with kexec patch that was posted for your primary ?

When I want to install ubuntu desktop as secondary ROM, I got this error: Failed to extract rootfs.tar.gz archive!

Does someone know what is wrong?
[Nexus 7 Original Development] davide95a:
I solved this issue by flashing an older version of the modded TWRP. The 20150630 worked properly. Probably a bug of the newest versions. I didn't try the 20160209.
[Nexus 7 Original Development] Thomas_xxxxx:
But the older version of TWRP can flash 6.0.1 ROMs?
[Nexus 7 Original Development] davide95a:
I don't know.:confused:
[Nexus 7 Original Development] MupEHcEH:
Yes, this is what i wrote few posts back. I guess there is some issue with the latest TWRP, I also used old multirom and CM11 (KitKat).

No, but once you install the ubuntu you can update TWRP and multirom. Then you can ADD lollipop and marshmallow based ROMs, however do not Install them (as primary/internal) because (I think) it will mess the boot and ubuntu will be gone again. Instead you ADD the newer ROM (5, 5.1, 6 ...) and then you can make it default if you want to :)

Just to complain .... I was struggling for maybe 2 weeks to find all those small things to be able to install multiple android and linux roms... I did it, it finally worked .... and I dropped my tablet and the touch screen does not work anymore :( Horrible.

Once after you install
[Nexus 7 Original Development] Thomas_xxxxx:
So which ROM should be internal? I want to boot ubuntu from USB so it cannot be internal. And you wrote that android ROM not to install as primary too.

does this work for android 6.0.1

do i need a special Kernel w/ kexec-hardboot patch - for android 6.0.1 or the android 5 works?
[Nexus 7 Original Development] MupEHcEH:
The only way I made it work:

1. Wipe everything

2. Install old TWRP

3. Install old ROM, in my case CM11

4. Install old version of multirom

5. Install the multirom manager, but when it asks for updating the multirom i unchecked it and left the old version

6. Install kernel that supporst your old ROM

With these now you can install linux distros, I tried ubuntu touch, plasma, bodhi, ubuntu desktop,.... everything worked, so...

7. Install linux distro

But now that TWRP does not support new ROMs, so

8. now you flash TWRP and multirom with a newer that does support them.

9. ADD the newer android based ROM, as I said do not INSTALL, but ADD, otherwise you would mess what you have done above.

Now you should have it all working, you can make your 6.0.1 to be booting by default, you can install on it multirom manager and update kernel.

I think i haven't messed something in the steps but that should be it... Little complicated, but as I said that's how i made it work, and in order to have Ubuntu i needed at least 2 android ROMs :)

So if you decide to try it and doesn't work just write here :)

I came to point 7. When I want to install ubuntu desktop on USB flash drive, it shows this error: "Failed to decompress the image, more space needed?". I found that it can be caused because of not using FAT32 format. I used FAT32 too but with no success. In the internal storage it is successfuly installed. Only USB doesn't work.
[Nexus 7 Original Development] MupEHcEH:
I haven't installed it on USB, but i think the error message says it clearly enough... check your flash, also check back in the posts how to exactly install it on USB, there might be something you are missing.

Of course, I have enough free space on flash drive. That is not the problem. I repaired bad sectors on flash drive and formatted.

Hi there, I'm having the same issue installing ubuntu-13.04-preinstalled on my N7 2012. Been using Multirom for about a year now and it has always worked great. I upgraded to v33a and then was forced to reinstall Ubuntu 13.04, due to a failed dist-upgrade-nothing to do with MRom. Removed the old Ubuntu 13.04 (had installed fine under v32) and attempted to reinstall it from exactly the same package. Error: "Failed to extract rootfs.tar.gz archive!". Redownloaded the package several times in case of corruption. Didn't work.

Eventually tried Arch Linux from an mrom package made from a rootfs.tar.gz from ArchARM. Worked but then ran into the same error I've had with any Linux rom, rom_info.txt specifies the filesystem incorrectly (f2fs instead of ext4) although its an easy fix and probably unrelated. Bluez5 bluetooth package doesn't play nice with my N7 2012 so I want to go back to Ubuntu.

Perhaps v33 added some extra verification for the rootfs.tar.gz which incorrectly applies to Ubuntu, or maybe the Ubuntu img is due an upgrade (to mrom?)?

Using Multirom v33a with TWRP 3.0.0-0 (default MRom recovery) on a 32GB Nexus 7 2012 with default filesystems for all except cache (f2fs). Only CM12.1 and Arch Linux are currently installed and there is approx. 8GB free space.
