@OP

If I understand correctly the secondary ROM is installed on a folder or to IMGs to which the partitions are mounted, and thus no problems are faced, right?

I am working on a kernel with something similar but I won't use a recovery and it will be limited to triple-booting (for now) with no Ubuntu support.

What I will do is bind the /system to a folder to which system.img is mounted and the same thing for data and cache. So basically the secondary ROM files are installed to a folder anywhere and the IMGs pick up those files and boot up.

My question is:

a) Do you think anything will get broken in the secondary ROM because of this?

b) I am executing a script called by init.delta.rc that makes the N7 boot using the IMGs. Do I need to edit anything in the init.rc as you have done?

I can't test it right away, but I have the code ready.

Just waiting for an answer to my question.

Good luck with your work.

Running Ubuntu-Desktop from USB-Drive

Hey Guys,

when I try to install Ubuntu Desktop on my USB Drive it stucks at creating root.img (for over 2 hours now), I am using multirom v8 and the 16GB version of Nexus 7. It's a 64GB USB3 Stick, formatted as NFTS. Do you know how to fix this?

I have another question... is it possible to install the packed Linux ZIPs for Plasma, Arc and WebOS on usb stick?

Sorry for my bad english and thank you for your work.

EDIT-1:

Someone who has less then 10 posts on XDA so he can't post in Dev Section told me that NFTS is mounted as Read-Only. I formatted the Stick asFAT32 now, and it works now.

[Nexus 7 Original Development] J_Caselles:
Regarding the second question, it is not possible, unless there is some way I'm not aware of to make a backup of the ROMs other than internal. Actually, this could be a nice feature for next updates of MultiROM.

Ultimately, you can always make a backup of your internal ROM, flash those Linux NOT with MultiROM ZIPs but the normal ones provided by their developers, try to make a backup of those if it is possible (not sure about that), Restore your Internal Android ROM, and flash those backups with multiROM to your USB stick.

about your first question, may you post your entire flashing procedure for us to make sure you're flashing it correctly?

I think that you can only backup android roms...I've also tried to build myself the root directory extracting the image of plasmaa active and add the rom_info file (as Tassadar explains in gifthub)

When I installed multiROM I already had a different ROM in the internal slot other than the stock one. Now I want to have the stock image in the internal slot and keep my other ROMs in the other slots. Can someone tell me how to do this? I've tried to flash a stock image I found but it failed. And if I go in the nexus toolkit and try to flash the stock image it says it will erase everything on the tablet completely and I don't want that. I just want to replace what's in the 'internal' slot with the stock image without altering the other ROMs or data on the tablet. Is this possible?

No, it's the right one. Dunno if it actually works, though.

Which data are you willing to save? you could do a backup of internal (CM), flash all .img unless the recovery.img, of the factory image (open the image, open the zip inside the image, and there are they) and flash back CM with "Add ROM" -> "from backup". You will need a full wipe anyway, coming from CM to stock. Extracted from http://xdaforums.com/showpost.php?p=36241372&postcount=609

Re: [WiFi&3G] MultiROM v8 (new recovery for Ubuntu Touch)

You can flash the stock 4.2.2 kernel with the kexec patch linked in the op, or you can flash one of the custom kernels that has kexec.

I recommend using m-kernel, it's a common combo with PA and Aaron uses it as well.

Recovery updated to TWRP 2.4.2.0: http://www.mediafire.com/?eprykjxx4buqxy4

Again, as for porting to another device - probably nobody else than me can/will do it, because the code is not ready for use on multiple different devices, and you'd have to know how to code and actually take the time and understand structure of MultiROM to port it to another device. Plus, _I_ don't even know what exactly woud have to be changed, and I won't know until I try to make it compatible with some other device - and I don't _have_ any other device. Somebody offered me that he could test it for me on his N4, but that would be terribly slow thing to do.

The LG P500 MultiROM is actually completely different thing, it is like that because when I was making MultiROM for P500, I didn't really know what exactly I want to do....and the final product looks exactly like that - the whole thing is just terribly confused and hard to use. Thus, the N7's MultiROM shares almost no code with P500's MultiROM.

Ubuntu touch daily builds started today, but they are not compatible with MultiROM yet, the patches are not there, so don't flash it just yet. It should be okay in couple of days.

I guess it wouldn't help much, What Tassadar is saying is that he would really need to go on a trial and error procedure, and this means build crash build crash until who knows when, it would be terribly slow something like (blind)build-send-download-crash-feedback-understand the feedback-(blind)patch-....

Another thing would be to team up in a GitHub project for not just testing but developing actively with more people than Tassadar... I'm sure there is a lot of Nexus 4 owners that would love MultiROM in their devices and do have the needed knowledge to be involved! They may be already in this thread, they may not know about it yet! spread the voice! ;)

Hey guys,

i installed MultiROM 8 and it works fine, but i have a problem with TWRP... i cant mount USB Storage.

Is there a little trick or a fix?

Greets

//Edit: Im using the latest TWRP version (TWRP 2.4.2.0)
[Nexus 7 Original Development] stadicon:
I think there is some issue with the latest recovery. Installing it, prevents any of my Linux ROMs to actually boot. After i select any Linux (for instance Bodhi or Ubuntu) on MultiROM menu, i get a restart and end up on recovery. I've tried reinstalling my kernel, multirom, patching boot process etc. Nothing worked, until i reinstalled the previous recovery build.

Note, i am working on a Nexus 7 3G.
[Nexus 7 Original Development] Tasssadar:
Yeah, I broke it. Recovery had wrong kernel which doesn't work with older kexec-patched kernels (the ones you flash to internal memory). Basically, the boot process with older kexec-hardboot patch was like this for no reason:

1. Linux ROM selected
2. Its kernel loaded into RAM
3. Reboot to "recovery"
4. Recovery's kernel detects another kernel loaded in RAM and runs it instead of starting recovery

So, it needed also recovery's kernel to be patched. I forgot that I changed recovery's kernel, so it didn't work and just rebooted to recovery. With never kexec-hardboot patch, it looks like this:

1. Linux ROM selected
2. Its kernel loaded into RAM
3. Reboot normally
4. Your main kernel detects another kernel loaded in RAM and runs it instead of starting MultiROM UI again

...so recovery is not involved at all.

Anyway, here you go: http://www.mediafire.com/?ujz1rlw92klnf7c
[Nexus 7 Original Development] stadicon:
Ok. Works like a charm, now! Thanks for the quick response and the explanation. Does this mean that when my kermel (M-kermel) updates (i mean, when the creator applies the correct patch) it will work the second way?
[Nexus 7 Original Development] Tasssadar:
Yeah, but Metallice doesn't have to update the patch, it is minor change and if I didn't screw up, you wouldn't even notice it. Please, do not tell 3rd party kernel developers to update because of this, it is really _very_ minor change, and it is already quite awesome that they accepted the patch in the first place.

To be honest, it's all my fault - that rebooting to recovery shouldn't have been there in the first place, I was probably just too lazy to check it all properly and think of the consequences until it was too late. Well, it changes nothing for you as users, it just is ugly.
[Nexus 7 Original Development] stadicon:
No, of course I won't ask about it. I am not that kind of guy. :) Besides, it won't make any difference on me. I was just asking because I wanted to make sure I understood the concept correctly (let's say it's a noob dev curiosity). Thanks again for the wonderful work you are doing. :)
[Nexus 7 Original Development] AssailantLF@gmail.com:
I asked this a few days ago, but it got buried in some other discussion, I think.

Just for clarification, there's no way to have multiple roms installed and share apps/data between them? Without the ability to do that, I feel like I'll primarily use this maybe try some linux stuff and just preview ROMs before actual use. My assumption is that it probably can't be done or something, but it sure would be more of a utility that way. :P

multirom uses a custom version on TWRP. if you flash the regular TWRP, you'll lose the multiboot options because they aren't built in. just reload the recovery (modified TWRP) from the 2nd post and you should be fine.

Re: [WiFi&3G] MultiROM v8 (recovery updated)

I tried every kernel in the op and stuck with m-kernel.. I have read that if you want 1.7ghz to work you will have to over volt that frequency.. Runs fine at 1.6ghz without the OV for me, but I normally just stick to 1.3ghz...

Over clocking the gpu is where I see the best performance increases on my tablet. I run mine at 500mhz to smooth out my 3d games and works great for me.

Re: [WiFi&3G] MultiROM v8 (recovery updated)

If you have an app installed on the first internal, and then install the same app on one of your secondary roms, it will indeed grab the data from the other, providing the data is on the main internal sd. I have minecraft on the internal (main) rom, and installed it on a secondary rom as well. When opened, it had all the data from the internal. Same game saves and all. So if your app meets those criteria, then yes.

And no, i did not tibu from the internal to the secondary. However, if you tibu in the internal rom, you have acces to those backups from within tibu in the secondary. I probably could have stated all this clearer, but i am pretty tired.
