Probably i did something wrong but...

After V3 (excluded) i can't boot in any way the internal ROM, if i press on the Boot button in the MultiROM menù the red toast appear but it's stucked and i've to force shutdown the tablet :/

I tryied with M-Kernel (which in the past it was working for me) and Trinity, i tryied to press on "Inject Current Boot Sector" too but it always crash/stuck on the red toast :(

With V1,V2 and V3 i had no problems and i'm doing the same steps as before :S

Yes, but it doesn't really void your warranty. I unlocked rooted put ubuntu (just an example) on mine and then locked and ASUS didn't make any problem with repairing it.
[Nexus 7 Original Development] Zero Night:
How do I change the internal rom?
[Nexus 7 Original Development] N@th_OC:
You flash it normally with or without wiping and after in multirom do "inject current boot partition".

On the first post:

Updating/changing ROM in internal memory

First, make that internal ROM is active - simply boot it. Then, go to recovery and install ROM's zip file. Finally, do Advanced->MultiROM->Inject curr. boot sector. ;)
[Nexus 7 Original Development] bjo12:
After hours of trying I succesfully installed and boot to ubuntu in my N7. Now my question is, is there an app in ubuntu in which I can OC the CPU to make it snappier? I know that since this ubuntu is a port it may not be just like the desktop in terms of smoothness.. kindly correct me if I'm wrong cause I'm a noob in this multirom.. and TS and other members please forgive me if I offended you in any way by post.. cheers mates! :):beer:
[Nexus 7 Original Development] nadiros:
So I read earlier that to back up an added ROM we can copy the folders using the file browser in recovery and then paste them back when wishing to restore.

This method does not work for me. Is there a trick to it or am I missing something? Has anyone been successful in backing up and restoring a ROM that is not the "Internal" ?

Edit* BTW this procedure just ends in a bootloop :(
[Nexus 7 Original Development] xela92:
Maybe it's a permessions problem. Try wiping system (manually removing files) and reinstalling the ROM over the existing restored one.
[Nexus 7 Original Development] lintz:
Not as for now. If you want it snappier you can always try Bodhi packed by Xela92.

Bodhi is a Ubuntu based distro (arm ver is debian based) ,aimed at being lightweight. And using Enlightment as wm instead of Unity.

[Nexus 7 Original Development] gemj95:
No one can help me :( ?
[Nexus 7 Original Development] N@th_OC:
I think it as to be related to kexek-hardboot .

Try a new time with trinity kernel for ewample.

Flash-it do "inject curr boot sector".

If it's not working.

Sorry but you have to flash a boot.img (any boot.img. take one in a rom zip file).

wipe everything and re-installed v6

or you can wipe cache and flash a new rom then inject curr boot sector.

Maybe it's your internal that is dead so if you don't want to delete your data just wipe cache and flash a new rom

I tried a while back when MultiRom just came out and "Flash GUI" didn't recognize the "recovery .img", i guess because it's modified . Try it and if it doesn't work use "CWMR Touch installer" and choose "Flash Other recovery"

[Nexus 7 Original Development] jawonder:
He's talking about using and app from the Playstore call "Flash image GUI" , there's no problem using fastboot . "Flash image GUI" and "CWMR Touch Installer" are apps that can be used to flash ".img files", i.e.- a Kernel or a recovery if you don't have access to a PC .

[Nexus 7 Original Development] tiny4579:
I don't remember where it was posted but its the way the permissions are set on the folder.

If you need to view it you can see it from /data/media/0/multirom on 4.2 or / data/media/multirom on 4.2.
[Nexus 7 Original Development] viper08:
This will help explain - its taken from the multirom wiki..

https://github.com/Tasssadar/multirom/wiki

Note that you can't access /sdcard/multirom in Android, because it has chown root:root && chmod 770. The /sdcard is not direct symlink, but mounted fuse filesystem, which does not run with root privilegies, rendering it unable to enter multirom directory. It will look like /sdcard/multirom is empty, but it is not - you have to go to /data/media/multirom. It is like that because Android's MediaScanner kept scanning the folder, which generated unnecessary battery drain.

MTP access via computer will also do the same thing - it will look like multirom directory is empty.

Post the log. Usually is in /sdcard/multirom/errors.txt

The problem usually is that zips are not-so-standard, and have boot.IMG in a subfolder of the zip tree.

You should put it in the root, so that multirom can find it and work. Hope it helps in this case, too.
[Nexus 7 Original Development] DragosP2010:
Or, it hasn't at all.

I repeat my question.

If I select to install a new rom (with multirom, of course) internal, my previous rom will be erased? Or it will be in the menu and I will be able to select one of them?
[Nexus 7 Original Development] xela92:
You can't have multiple internal roms. 1 internal rom, all external roms you want.

If it doesn't have a boot.img, put one inside for it.

It's a cm based rom? Use cm kernel. It's not? Try another. I have no other ideas...

Hello!

I just stumbled upon this thread and I'm really fascinated by your multiboot approach. I had a few quick peeks in your source code and it looks really elegant - thanks for sharing!

But I unfortunately don't own a Nexus 7 so I'd hope to be able to port this to the Nexus 10 as well, would this be okay for you?

And I have one more question for the Ubuntu (or Plasma Active) port, because that's the main thing I want to achieve:

How and where is the initial ramdisk (initramfs) generated? I compiled a kernel for the Nexus 10 with CONFIG_VT, framebuffer and kexec enabled and wanted to test the boot ubuntu process using "fastboot boot boot.img". But I'm lacking a initramfs that is able to mount the rootfs from an ext4 file system image that's located on the iternal storage. How did you achieve this?

Thanks for any help and your work!

EDIT: Is there any source code for multirom_installer / multirom / trampoline available?

EDIT2: Found it in Tasssadar / multirom / trampoline

Preparing ZIP file...

Erasing incomplete ROM...

Updating partition details...

For the curious ones, this is how to clone N7 screen through wifi http://esrlabs.com/android-transporter-for-the-nexus-7-and-the-raspberry-pi/ and it requires a specific ROM.

Thus the importance of MultiROM.

If you read the OP and post #2 there's patched Kernels that MultiROM requires to function. You can flash whichever one is best over your

stock ROM without having to wipe anything.

I am using motleys kernel with no issues and have CM10.1 as internal and Mmuzzy's AOSP as an alternate. All the info is in the OP for an easy install.

Wouldn't it be possible to create zips with empty directories to simulate wiping in MultiROM? Maybe wipe "cache", "dalvik-cache", and " factory reset".

Not sure if this has been asked, but how do you flash new kernels to the internal ROM? M-Kernel, to be exact. do I have to use the inject options or just straight flash?
[Nexus 7 Original Development] rebel1699:
Straight flash as normal.
[Nexus 7 Original Development] xela92:
I don't think it would do that (erasing). And it's not a good idea to create zips that erase things on sdcard (I see the danger inside).

If you need to wipe a ROM and you don't want to do it manually, delete it and recreate it.

Re: [WiFi&3G] MultiROM v6

What will the USB stick show as when selecting the install location?

So far when I plug my USB in I get:

Internal memory

And dev/something/sda1

I know what the internal is but I wasn't sure if the dev/...../sda1 was the USB stick or another ROM install(i just added webos, thanks tassadar for the .zip)

Edit: sorry for all the silly questions I've asked I just like to know as much as possible before I do anything.

USB not essential as it installs nicely on the internal storage under a seperate multirom folder and is able to boot from that....

I know what you mean. You want a flashable zip file and not an img file. I dont think there's one. You'll have to manage to flash the img file into your device somehow.

Re: [WiFi&3G] MultiROM v6

I dont see a point in downloading wugs when fastboot is so small and easy.

Fastboot flash recovery recoveryname.img

Easy as that. Why waste bandwidth, time and space?

Toolkits are actually more complicated than fastboot. Fastboot is as simple as it gets. The gui of a toolkit is no more than a placebo of ease of use. In the computer age, typing on a keyboard should not be feared.

how do i include Kernel w/ kexec-hardboot patch (CM 10.1)?
[Nexus 7 Original Development] rebel1699:
Re: [WiFi&3G] MultiROM v6

How did you try installing bodhi? You dont install it in the multiboot section of modified twrp, but in the opening menu like a normal internal rom. There is a file within the zip provided in the op that tells it to install as a secondary to the sdcard/multirom directory. Tjhe zip in the op also already contains the correct kernel. No need to replace it.
[Nexus 7 Original Development] bradman117:
ohhh

is bodhi more reccomended?
[Nexus 7 Original Development] rebel1699:
Re: [WiFi&3G] MultiROM v6

Bodhi is pretty good. I think it is actually a little ahead of ubuntu, for me anyhow.

Re-readimg your post, the kexec enabled kernel you need to install to internal can be found in the multirom thread. Second post in that op. Match it to your internal rom type (cm 10.1, aosp, ........). That will allow kexec to redirect to the kernels of the other roms when you choose to boot them.

I would also recommend reading the entire multirom op for a better understanding of how and why it works. It is very helpful in future troubleshooting and maintenence.

Edit: This IS the multirom thread, lol. I thought I was in xelas thread! But, the info still stands. Download the bodhi from xelas thread and read this op fully. Gotta remember where I am next time. :P
[Nexus 7 Original Development] browy:
Exactly, why should I waste my bandwidth, time and space. Like I said before, I used wugs to root my nexus 7. I already have it on my computer, it can do all the jobs just fine, so why should I go and install fastboost on my computer and then learn how to use it. I don't see the point of doing that extra step either since I can flash a file with 3 mouse clicks using wugs. And no, it has nothing to do with the fear of using the keyboard. I just do the method that takes less time for me.
[Nexus 7 Original Development] rebel1699:
Re: [WiFi&3G] MultiROM v6

I always encourage fastboot for one main reason- On occasion, using a toolkit can accidentally read your partition incorrectly. A 16Gb can all of a sudden be seen as only having 8gb useable, and 16 on a 32. Then, fastboot is the only alternative in which the flash-all.sh commands have to be used correctly to correct the problem.

If you have wugs, then fastboot is already downloaded, as that is what it uses to flash. It is merely a gui for fastboot, with huge added size. Fastboot binary itself is only a few k's in size. That is the danger in toolkits. That is info you should have already known. Dont take this post as insulting, but as sound info. Afterall, your knowledge of fastboot does not help or hinder me in any way, but could very well help you, yourself, greatly in the future in the case that a problem arises that a toolkit cannot repair. Fastboot is super simple. For example, to flash a recovery, you type "fastboot flash recovery recoveryname.zip. They beauty on a nexus divice is its simplicity to work on. Toolkits can sometimes be a case of "not seeing the forrest for the trees".

When you download a factory rom and extract it, open the flashall.sh file in a notepad, and all the commands are there. Fastboot is a very simply process, but hugely comprehensive.
[Nexus 7 Original Development] bradman117:
Re: [WiFi&3G] MultiROM v6

I'm glad I was able to try out fast boot due to it being my first attempt with a fast boot and was successful.. Good learning experience:)
[Nexus 7 Original Development] rebel1699:
Re: [WiFi&3G] MultiROM v6

Sweet! I understand why rootkits/toolkits are there, biut when dealimg with somethimg like multirom, its always best to use what the dev did to avoid issues. I mean, wugs most likely works fine, but I dont want to run the risk of having to do things twice or more. Hell, the fastboot commands can even be c&p into the term for added ease, and a tenth of the hd space as a kit.

But the number one problem I see is all the post where people need help, and wait hours for it, when fastboot could have fixed it in 2 minutes. Fastboot can literally be learned in 10 minutes or less. If it were up to me, google would include a fastboot index card in all their nexus device boxes. So many problems would be avoided.

Did you download the zip from xelas post? If so, there is no need to open the zip, as it is preconfigured to install correctly. Reboot to modified twrp, and click install. Choose bodhi zip, and swipe to confirm. It will not erase your internal or replace it. The other linux roms do not get installed from the advanced-multirom section like ubuntu does.
