There is no problem with not sharing kernels. I never choose to share the kernal and I have never had a problem. I think that is the recommended option.

From my understanding, if you choose to share a kernal, you have to be especially careful that the kernal on your primary system will support the new ROM (in terms of CAF or Non-CAF support). Otherise , the secondary ROM might not boot. You also have to be careful when flashing a new kernal on your primary system as your secondary Roms depend on it.

That's from my understanding, but I might be wrong. I recommend however, that you choose not to share the kernal

[Nexus 7 (2013) Original Android Development] roofrider:
No problem at all, i think the problem will arise only if the shared kernel in not compatible with the guest/2nd rom. Possibly something like a CAF-AOSP clash.

I don't share any kernel, though if there is any particular advantage in sharing them i might give it a shot. Maybe if the kernels are shared swapping primary-secondary roms will be easy? I dunno, the last time i tried swapping roms with wavering attention, it turned out to be a mess. :D

Is there an easy way to change the twrp splash screen at startup? I downloaded TWRP_multirom_flo_20140308.img and used Android Image Kitchen to swap the curtain.jpg. Reflashed and worked as expected but the MultiRom Manager app shows no recovery installed. When I update it goes back to regular splash screen.
[Nexus 7 (2013) Original Android Development] z31s1g:
Here's what tasssadar posted a few weeks ago in another thread:

Attached you'll find a "repackimg_mr.bat" to use with the Android Image Kitchen. I'm using it for creating the repacks for the Holofied themes.

It has the required argument included. Just drop in the kitchen folder and use it instead of the default "repackimg.bat".

As a result the multirom app will detect your repack properly.

[Nexus 7 (2013) Original Android Development] basily:
Anyone? I'd love to have Ubuntu touch installed to experiment with but it just takes up too much space on my tablet.
[Nexus 7 (2013) Original Android Development] Alucai Vivorvel:
Why not try it yourself? Back everything up and go ahead. I don't think many people install ROMs to external storage. Computer OS's maybe, but for a mobile device? Doubt that's very common.

Also, what size is your tablet? I have a 32 GB with three ROMs (including Ubuntu) on the internal memory.
[Nexus 7 (2013) Original Android Development] basily:
Well, I have tried. But there doesn't seem to be a way, and least from what I can tell. That's why I'm asking.

I don't think it's so strange to install a ROM to an external drive if you don't plan to use it often. I have other data on my 32GB tablet which I DO need to have easily accessible.

For regular ROMS, there are options to install to a USB-OTG drive when installing via recovery, and for a manual install I could do that for Ubuntu as well, but the appropriate zip files for that sort of installation don't seem to be available AFAIK. Also, with an Android ROM you can do a backup using the Multirom options in recovery, but not for an Ubuntu ROM.

So, I'm still hoping someone might know of a way to do this, because, if it's possible, it's not apparent to me.
[Nexus 7 (2013) Original Android Development] Alucai Vivorvel:
I think it's failing because Ubuntu's file structure is so different from Android, that MultiROM and recoveries just don't know what to do. Gotta love Linux, eh?

Keep in mind also that everything's subject to change at this point, so it wouldn't really be worth it for developers to configure everything just so Canonical can go mess it up with a minor update.

If no one responds saying they've successfully installed it, perhaps you'd be better off waiting until the dedicated tablet release. Can't remember when exactly that's supposed to be launched, but everything should be a bit more stable at that point.

[Nexus 7 (2013) Original Android Development] Alucai Vivorvel:
There are like four different kernel patches it can install, there's a drop down menu. Are you using an AOSP (stock) based ROM, or some variant of CyanogenMod?

Can I use this to have a pure stock partition (so I can run Sky Go) and a rooted, custom rom?
[Nexus 7 (2013) Original Android Development] Alucai Vivorvel:
Yes, you can! If, that is, you use the "Manual Installation" method as mentioned in the first post of this thread, as otherwise you'll require root (and I don't know if Sky Go works with rooted ROMs? Probably not, if you're looking to go back to stock). First, flash completely back to the stock ROM (back up everything first though, as all your data will be wiped) using Wug's Nexus Toolkit. Download your custom ROM of choice and GApps, and boot into recovery. Go into Advanced -> MultiROM -> Add ROM -> Next -> ZIP file, and swipe to confirm. You'll have to go back to the MultiROM menu in the recovery, List ROMs, and select your newly installed custom ROM in order to flash GApps I think (someone correct me on this if I'm wrong).

I have CM installed as my second ROM (Not internal)

I'm on nightlies, and was wondering if using apps like CM Updater would screw up my primary (internal) ROM?

Any ideas?

EDIT: I went ahead and tried it.

It downloaded updated .zip rebooted into recovery and didn't do anything.

Manually went into MultiRom selected second ROM, / flash zip and flashed update.

Rebooted and it's fine.

I guess it's half a win, - i don't have to download full ROM nightly just the updated .zip, but i do have to manually flash it.

it's all good.
[Nexus 7 (2013) Original Android Development] gravedigger76:
A possible suggestion for an enhancement...

If at all possible to allow secondary ROM (s) to share installed apps that would be so sweet. Only need to have the app take up single instance of install.

Just a though. :)

Hi [MENTION=3418703]Tasssadar[/MENTION],

It's really annoying if the second roms don't share kernel with the internal when the device has to boot all again from the beginning after selecting which rom to boot (to reload the kernel, I guess). So can you add the function to switch between "share" and "don't share" again after installing a rom? I think not many people want to install a brand new rom just to switch between the 2 options.

Thanks a lot.
[Nexus 7 (2013) Original Android Development] Tasssadar:
In recovery, Advanced -> MultiROM -> List ROMs -> *rom*, there is a button Remove boot.img. This action switches ROM to "share kernel" mode. Flashing a ZIP which contains kernel (even ROM update!) into that secondary ROM puts it to "don't share" mode again.
[Nexus 7 (2013) Original Android Development] thecdn:
I just tried my device and it doesn't work. Must have confused myself when I was flashing different kernels. I blame my high blood pressure and sinus headache.

Either that or I'm an idiot.....

It's not working for me, the screen is way trippy. Do you have any tips of what I may not be doing correctly? MultiROM works for other ROMs, I have checked the md5 of the b2g file, and used both "share" and "don't share" kernel settings. It boots, and seems to be functional but the screen is bright pink and flashes quickly, text is overlapped, and things seem to not fit on the screen.

EDIT: Other ROMs don't work. They seem to boot fine, CM showed boot animation, but then screen glitches out. I hope this is just something I'm overlooking with my noob blinders.

TIA

There are several ARM compatible distros, including debian, Ubuntu, arch, slitaz, and a ton of Ubuntu/debian derivatives. There are plenty of ARM computers.

[Nexus 7 (2013) Original Android Development] Alucai Vivorvel:
My apologies, you are correct. Though perhaps once Canonical has fully ditched Android code (I believe they have been working on that for some time now) they will release the source code and make it possible to boot other distributions on a mobile device?

I doubt that somewhat, as it seems they aim to make some sort of profit after all this development, but hopefully most of their work will be open source.
