Hello guys i used to use multirom on my nexus5, Nexus. It was amazing experience. To have multiple roms at same time trying new features. also it was greet way utilize different rom for different purpose of my life. Multi user limits functionality and also slows down a bit.

So my question is which latest devices with good specs support multirom. any help will be really appreciated. IF you can provide me list i can purchase device accordingly.

Thank you so much in advance.

Rom Install Failed

Hi

thank you for the excellent work. I have managed to install ubuntu and it works great I have stock rom in internal memory and ubuntu as additional I wanted to install anothe android rom such as cynogen and it starts and comes up with an error Rom installation failed and it says cannot read/data/media please help
[Nexus 7 Original Development] Tasssadar:
Okay, status update - MultiROM v3 is basically done, now I have to "just" update the recovery with support for ROMs on USB. I'll probably release it sometime next week, because I'm out for the weekend.

I am also waiting for Ubuntu & CyanogenMod to hopefully accept some patches required by MultiROM, it seems promising :)

PS: Thanks again for the donations, it is very much appreciated, especially before christmas.

MultiROM stores all data in /sdcard/multirom, so it the space is shared with all your other data.

I tried that, but Android does not like it if the permissions are different, so it just erased all app data.

Depends on the kernel. If it is using AnyKernel installer, it should be okay. If it uses that aroma thingy or it is distributed as boot.img, you have to select "Inject curr. boot sector" in recovery after installation.

When does it says that? In recovery? Could you write the whole error/get the log files?
[Nexus 7 Original Development] Solarian:
I installed everything based on the OP, so I guess I'm running 12.02? No real way to check. Well, Ubuntu seems to be a laggy summabish, but I'm still very impressed by MultiROM and I'm really looking forward to optimizations in future versions of Ubuntu. Browsing in Firefox under Ubuntu is soooooo much better than any Android browsing experience, and I'm installing some Libre Office now. Overall, awesome job with this mod, it's amazing!

Found where to check, I'm on 12.10.

Nice it works now!

Upgraded from 12.10 to 13.04 without bluetooth support
[Nexus 7 Original Development] Tasssadar:
I may have a fix for that "media scanner keeping device awake and eating all the CPU" issue - do this in terminal as root:

For 4.1:

chmod 770 /data/media/multirom
chown root:root /data/media/multirom

For 4.2:

chmod 770 /data/media/0/multirom
chown root:root /data/media/0/multirom

Please try to boot all roms you have, see if it works and does not cause any problems.

EDIT: You won't be able to go into multirom folder without root, but neither will the MediaScanner. As far as I know, this is the only possible solution.

Any chance of support for Aroma installs?
[Nexus 7 Original Development] -viperboy-:
Just picked up an N7, tried this out and it's really cool! One thing I will just let you know, I booted up into ubuntu, wanted to go back to Android so I hit restart. It then started to restart into ubuntu but then the multirom screen came up. As it booted into my internal ROM (PA), my data wasn't there and it looked like a fresh flash. Confirmes that the multirom folder doesn't exist anymore.

Has anyone else seen this? Was this a freak thing or should I be shutting down ubuntu and not restarting? Thanks again for this!

I'd say make sure you installed both the zip and recovery image properly, check to make sure permissions on the multiboot folder are root:root, and of course, make sure you have enough space.

[Nexus 7 Original Development] Raudi1:
CyanogenMod just got released for tilapia:laugh: And it requires a tilapia recovery:( How do you propose we handle using CyanogenMod (or any other ROM that requires the tilapia recovery) and MultiROM on the Nexus 7 3g? I don't know how difficult it would be for you to build a recovery for tilapia, but that would be the cleanest solution I think.
[Nexus 7 Original Development] Tasssadar:
Did you install new recovery? Also, the filename must end with either img.gz or .img.

Don't see reason why CM should "require" tilapia recovery, other than the fact that it checks if it is tilapia, and refuses to install if it is not.

From what I can tell by looking at the installation script, you should be okay just removing the first line in /META-INF/com/google/android/updater-script file in the installation ZIP (the one which goes "assert(getprop("ro.product.device") == "tilapia"...")
[Nexus 7 Original Development] EvanA:
Yes, I'm using the latest recovery (2.3.2.3) and the image ends with .img.gz. If I rename it without the .gz extension it is visible but fails to flash.

Nevermind, it turns out the recovery flasher I used didn't work properly. Flashed recovery via fastboot and all is good.

Sent from my paranoid+m-kernel nexus 7
[Nexus 7 Original Development] XYunknown:
You can not just "rename" the file. .gz means that the file is compressed. If you like to get the .img file of it, you can use the "gunzip" command either in your devices' terminal emulator or in any other linux terminal (gunzip is standart part of most linux systems)

Can you make a version with support of ubuntu 13 and with that old style switching kernel..i use power saving kernel and i apsolutly love it because of no single bug and awsome battery life but i now that there is very small chance that it will be patched with your patch.

[Nexus 7 Original Development] Raudi1:
You are right. But since I flash new nightlies every few days, it would mean a lot of work each time. Also things like the CyanogenMOD updater wouldn't work and I guess the signature check would fail as well and increase the risk of flashing a bad download.

So for me the best solution would be a recovery which returns getprop("ro.product.device") == "tilapia":)
[Nexus 7 Original Development] Tasssadar:
Recovery must give more than that. Get me the recovery log.

Try this recovery, it should return "ro.product.device=grouper", but also "ro.build.product=tilapia": http://www.mediafire.com/?kr4t5pkj2y6vxi2

I have my current rom installed and nandroided so I installed the multirom zip and fastbooted twrp. The internal rom is aokp 4.2 and if I install multirom.zip I can no longer boot my internal, first it lets me choose internal then freezes at the google screen. If I reinstall my current rom it will boot but multirom ui goes away. Then if I reinstall multirom.zip and reflash my rom plus reinject current boot it does the same. sorry if this sounds a little bad as it is really hard to word it.

so basically If I flash multirom.zip i cannot boot my internal rom whatsoever, if rom is reinstalled and bypasses multirom it boots fine.

ubuntu boots fine thank you so much for that

Edit: was able to boot into android successfully once, but ubuntu boots every time. Don't know why internal rom is being so difficult.

EDIT2 - I done a complete wipe of my tablet, including sdcard, flashed stock 4.2 applied it all again, and it still hang on Booting Rom, i am running trinity kernel, let me try without that.
[Nexus 7 Original Development] ksqp:
What you say is true, but only for devices with an x86 CPU (i.e. a PC or Mac). It's because you need to be able to install Windows in the virtual machine, and Windows is only currently made available for x86 architectures.

Maybe one day someone will work out how to install Windows RT in a virtual machine under Ubuntu on a Nexus 7, and then it might be possible to run Microsoft Office for Windows RT. Don't hold your breath though.
[Nexus 7 Original Development] Foka002:
OK this is awesome and something I have been waiting for. I got it up and running. Ubuntu is smooth and to have an options to choose between roms is just beautiful. I'm completed now and I can die in peace ;)

[Nexus 7 Original Development] kar10s:
Sorry, but that is a total nonsene. Athough you can use virtualised windows to run MS office, It is just waste of system resources, free space and money for Win license - as long as it will work on wine and to my experience, MS office is working fine on wine. I did not tested anything above 2007 as I do not have access to it, but I see no reason why it should not work. After all, MS Office was one of the main reason why was wine project started...

Another thing is, whether or not the wine itself got ported for nexus, but sooner or later it will be...
[Nexus 7 Original Development] Tasssadar:
It wil not wipe anything.

Give me link to that ROM, so that I can try it.

EDIT: Also, is your filesystem upgraded to 4.2 version? I mean, do you have the /data/media/0/ folder or not?
[Nexus 7 Original Development] ksqp:
What a rude reply.

I am very well aware of Wine, but user prestige777 asked if MS Office could be run in a virtual machine on a Nexus 7. I simply explained why it currently cannot, without making any comment about whether it would be the best way or not. I do not see how that information qualifies to be called "total nonsene" (sic).

Furthermore, as your experience of Office under Wine is somewhat limited, I can tell you that Office 2010 did not run under Wine for at least a year after its release, until Wine was updated to be compatible. So people wanting to run Office 2010 on Linux distributions at that time had to do it in a virtual machine or not at all. And modern PCs with multi-TB disks, quad core CPUs and 12 or 16 GB of RAM can run multiple virtual machines without any trouble at all - "waste of system resources" is a complete non-issue.

That may be so, but Microsoft Office for x86 will never run under Wine on a Nexus 7, so that's not actually going to help. Or are you assuming Office for Windows RT will one day be released by Microsoft as a separate product? Personally I wouldn't bet on that.
[Nexus 7 Original Development] Tasssadar:
Give me link to that aokp ROM, I can see at least 3 ROMs saying they are AOKP.

Also, can you get me logcat? "adb logcat" should already work in that "Booting ROM" phase. If not, try following - when it gets stuck on "Booting ROM" again, press power button for 10s until it reboots and then press both power button and volume down. When you'll get into bootloader, use volume up/down to select recovery mode and then press power button.

Whe you'll get into recovery, use adb shell on your computer and do this:

cat /proc/last_kmsg > /sdcard/kmesg.txt

File "kmesg.txt" will be created on your sdcard. Get me that file, it contains debug info from multirom.
[Nexus 7 Original Development] Warrior1975:
I had it working perfectly with AOKP 4.2 last night. Booted fine on the internal ROM portion. Awesome thing you made, thank you so much!! I've wanted something like this for a while, can't thank you enough.
[Nexus 7 Original Development] kar10s:
Well, first, its not meant to be rude or anything, It is more likely that his question sounded like he is not aware of the possibility to use wine instead of virtual windows, but yes, I might have got it wrong. So, once more, sorry if I offended you. I simply understand that question as "I want MS Office on my tablet".

Ok, thanks for enlightenment, but that does actualy mean that NOW it can be run correctly without virtual Win, right? And yes, most new SW (especialy that wich are ment for new Win) can have trouble runing under wine at first, that is common fact.

And for this, well, if you have Nexus 7 tablet which can be compared to system tat you have just described, then OK, you can do that without any noticeable impact on you system and I am sorry that I mentioned this subject, but I would certainly not try it on MY nexus which (sadly) has only 1GB of RAM :crying:

Well, first, I heard that MS is going to release office for android soon, so there will be no need for that. Second, as wine stands for "windows emulator" there is no need for similir architecture, if wine is ported correctly, because it should interpret windows api only, not use window libraries (although it can do that, it would not work on nexus or any ARM, you are right in that, but that has nothing to do with wine). Ok, right, I can not show you working example (I do not have it flashed yet, but now I certainly am going to test it soon), but that is the point of "emulator".
