Thought I found my problem, flashed the stock "modified" kexec kernel and it booted the secondary ROM. I think "inject curr. boot sector" is what fixed it.
[Nexus 7 Original Development] Tasssadar:
[MENTION=4393788]webdroidmt[/MENTION], [MENTION=4681892]jbaumert[/MENTION]: try this testing version (marked as v13t), see if it fixes your problem.

Is it possible to run plasma active 4 on multirom ?
[Nexus 7 Original Development] danizwam:
Hi,

i'm using MultiRom since June and switched last saturday from MultiRom_v10 to MultiRom_v13.

After switching to v13 ROOT isn't working anymore.

I am using CM 10.0.0 as a 2nd ROM and every App with ROOT-Abilities stopped working.

SuperSU tells me, thats something wrong with the su binay.

Titanium Backups tells me, that /system/xbin/su could not be found.

If i flash the same ROM (or the Nandroid Backup) with v10, ROOT works very well.

Any suggestions?
[Nexus 7 Original Development] Tasssadar:
Yes, it was very helpful, thank you. It was loading the wrong fstab:

multirom: Loading fstab "/fstab.grouper~"

Can you try it with this testing version?

[Nexus 7 Original Development] danizwam:
Doesn't work :(

1) Update from v10 to v13t --> no ROOT

2) Deinstall and install v13t, Restore from Nandroid --> no ROOT

3) Deinstall and install v10, Restore from Nandroid --> ROOT works
[Nexus 7 Original Development] Tasssadar:

Hi guys.

I have been using multirom since two days. I installed Ubuntu Touch from the links in OP. I wanted to know if there is any way of using terminal in Ubuntu Touch. I have been searching for this since yesterday with no fortune. Also wanted to check if we can install applications on Ubuntu Touch or not cos i saw some video tutorials few days ago in which people had many applications installed. I cant do anything apart from just viewing the 4 screens and dragging the notification bar(cant even change time & date)

And i have tilapia with GwT Rom as primary.

Installed as per OP.

saucy-preinstalled-touch-armel+grouper.zip

saucy-preinstalled-touch-armhf.zip
[Nexus 7 Original Development] mf01mf01:
These also good for tilapia (3G)? I ask because there is "grouper" in the title.
[Nexus 7 Original Development] phanitej:
I'm using tilapia, have for ROM's installed.

Primary: Synman's GwT 4.3 r6 (for 3g and stock android experience) along with M-Kernel_mr2 so that the other 3 ROM's boot

Secondary: Ubuntu Touch

Secondary: Ubuntu desktop

Secondary: Slim Bean 4.3 1.2

All four working fine without issues. It's just the recovery and multirom folks that you'll be flashing, so did not effect the 3g part on my primary rom
[Nexus 7 Original Development] mf01mf01:
Thanks! And the correct installation order?

1. With the existing CWM: multirom-20130923-v14-grouper.zip, then

2. TWRP_multirom_grouper_20130923.img, finally

3. kernel_kexec_430.zip

or

1. TWRP_multirom_grouper_20130923.img, then with this

2. multirom-20130923-v14-grouper.zip, finally

3. kernel_kexec_430.zip
[Nexus 7 Original Development] thereal_bigjake:

[Nexus 7 Original Development] phanitej:

Dear All,

I was on Stock 4.3 and have CF-Auto-Root previously. The I used the sequence

1. TWRP_multirom_grouper_20130923.img, then with this

2. multirom-20130924-v15-grouper.zip, finally

3. kernel_kexec_430.zip

and get MultiROM successfully. Then I installed Ubuntu Desktop into Internal as OP and the Ubuntu Desktop works like a charm!

However, once I boot into Stock Android 4.3, SuperSU says the SU binary is missing. I have tried the "Inject boot.img file" with the CF-Auto-Root img file but that didn't work. Any suggestion can I try to make SuperSu work again (I hope to keep Stock 4.3 as internal...)?

Thanks in advance!
[Nexus 7 Original Development] Tasssadar:
Just flash SuperSU ZIP in recovery again. Don't use MultiROM options for that, just Install menu as usual.
[Nexus 7 Original Development] macexplorer:
hi,

i have same problem as above. not able to get root in internal rom.

I am on older multirom (twrp 2.6.1.0)

I have already flashed supersu 1.65 and still no root.

How can i update multirom and twrp itself?

If I simply reflashing multirom files like new, will i loose the existing installed rom list?

BTW,

I am quadbooting my N7 wifi. Its freaking awesome!! feels like this is a desktop now :)

webos/ubuntu touch/ubuntu desktop and Plasma!!

Thanks!!!:good:

EDIT:

Just flashing over current, like new install, works. existing roms not affected.
[Nexus 7 Original Development] gofd:
Thanks, it works for my Nexus7!

Another question is about the screen layout (landscape theme) of the multirom (or in particular the "Boot" button"). Since mine's screen is faulty with 1/4 of screen not touchable, is recompiling the whole MultiROM the only I can move the "Boot" button to the bottom left corner in landscape theme?

If I need to compile MultiROM for that purpose, do I need to have the whole android source downloaded (~15GB!) and should I use the master branch or the nexus 7 branch of MultiROM?

Thanks a lot for the great MultiROM!

Hi Tasssadar,

I am trying to compile the MultiROM source to have the layout adjustment. I have the Andoird Source Tree ready to compile MultiROM Release v15 with libbootimg Release 0.1.2. Inially it did not work and warned me that

DEVICE_RESOLUTION was not specified
MR_DPI not defined in device files
MR_KEXEC_MEM_MIN was not defined in device files!
MR_INIT_DEVICES was not defined in device files!
MR_FSTAB not defined in device files

and has certain Macro not executed and can't proceed. I tried to provide certain values manually (DPI_MUL and force enabling the size enum in framebuffer.h), the make command produces some files (including the multirom file). However, after replacing the multirom file in /sdcard/multirom with chmod 755 in Recovery mode, the screen splash once but not showing any choice at all and boot directly into the first ROM. Do you have any suggestion?

Thanks in advance.

Sry guys, but search is temporarily unavailable, so I cant find an answer (but may be its already answered):

How can I make Backups for the secondary Roms in MultiRom / modified TWRP? Is there a way to do it?

Btw I´m on LG4X HD with MultiRom ModV12 and TWRP (unknown version, may be its to old and doesnt have that feature)
[Nexus 7 Original Development] webdroidmt:
Just download the latest TWRP v.2.6.3 linked in the OP to make backups of secondary roms. http://xdaforums.com/showpost.php?p=34577851&postcount=2

Although you don't need to for making the secondary rom backups, you should probably also update your version of multirom to v15 while you're at it.

Mike T
[Nexus 7 Original Development] Tasssadar:
Yeah, unfortunately you need the whole thing. But, you seem to have already figured that out, so I'll respond to your next post. BTW, I'd like to add option to control multirom via physical keys until next version, which should come out as soon as I can get somebody on the IRC and test something out for mako version.

You need to grab this device folder: https://github.com/Tasssadar/device_asus_grouper. Replace your existing device/asus/grouper with it.

No, it won't. It will create folder multirom-grouper on it and it will put ROMs only into that folder.

You need to update to newest recovery. Then, go to Advanced->MultiROM->List ROMs->*select ROM*->Backup.

Don't do anything, just grab the ZIP file and install it via Advanced->MultiROM->Add ROM in recovery. The ROM technicaly doesn't exist until you add it, so there is nothing you can wipe.
[Nexus 7 Original Development] gofd:
Thanks a million Tasssadar.

With the device file package, the master branch of multirom and libbootimg, I have successfully compiled the executable version with the "Boot" button moved to fit my faulty screen.

So now I have the full environment ready to contribute, anything I can help you or test?

Anyone any advice???
[Nexus 7 Original Development] Tasssadar:
Kexec was crashing because of kernel bug, which is fixed in newer versions of kexec-hardboot patch, but not all grouper's kernel have it. Version 16a should fix it for everybody. This problem does not appear on other devices because I fixed that kernel bug before releasing kexec-hardboot patch for them.

I didn't encounter this bug because I was using newer kernel, sorry about that.

Ubuntu Desktop for N7 isn't in active development anymore. That's mainly because of Ubuntu Touch, but also because the hardware is just too slow to run it properly, like on yours for example.

I was able to install the newest Ubuntu Touch (20131009.1) and get it to boot but, once in UT it was very laggy and would crash or the screen would bug out and start flashing. I don't think it is a multirom issue, just UT being beta and buggy.

It's probably the UT. It's very buggy and misses a lot of feature for the N7. (as mentioned in the recent XDA TV ep)

You can also try the kernel by your self and see if if works (should take the same time as asking the dev). If not, just flash an other one.

But it's only a twrp backup file to download no zip, and I want it to setup as second Rom.
[Nexus 7 Original Development] TheIronMaiden:
THats a pretty gay way of publishing a rom. You might be able to just download it, and put it in your twrp/backup folder , and I think there's an option to select it as secondary or move it to the ROM folder inside tue recovery via file manager. One of these guys will come up with a clearer answer

Edit: put the backup ROM in your twrp/backup folder. Then go to advanced/multirom/add rom folder and select android. Then select backup. Then select the back up rom as your secondary.

Thanks!
[Nexus 7 Original Development] flash5000:
You need to install MultiROM according to the instructions in the first/second post. Furthermore you need to flash a kernel with the kexec patch included to your ROM.

You won't loose anything by installing MultiROM.

Enviado desde mi Nexus 7 usando Tapatalk
[Nexus 7 Original Development] thereal_bigjake:
It's all in the op and pretty simple.. you only need a patched kernel if your going to run Ubuntu or Android only if you do not share the kernel. Just flash the kernel like you have always flashed kernels if you need it.

Install recovery

Install MultiRom from recovery

Install kexec patched kernel if you need it

Then enjoy and the op explains how to flash secondary roms
[Nexus 7 Original Development] Tasssadar:
New recovery was released. It automatically injects boot sector with MultiROM after flashing a ZIP file or using adb sideload. That means you don't have to click "Inject boot sector" every time you install different kernel, it does it for you. It can be turned off on "Confirm flashing" and "adb sideload" pages in recovery.

http://d-h.st/zRW

There's bug in Xorg which causes the "mouse button" to get stuck. I can't find the bug report right now, but it is possible it gets fixed with 13.10 release, which should be here in a few days. Most people using Ubuntu Desktop here just plug in mouse and keyboard and use it as a "netbook" of sorts, I think.

Ubuntu Touch switched to Mir and it doesn't work very well on grouper. Remove file /home/phablet/.display-mir and reboot in order to switch back to surfaceflinger, it is much smoother (but it will get removed soon, probably). You can do this command while in Ubuntu Touch, either in adb shell or use terminal app.

rm /home/phablet/.display-mir
[Nexus 7 Original Development] alcaprone:
Also for me Ubuntu touch seems laggy and after a couple of minutes stops responding..is there any other way of erasing display.mir? because for me it is impossible to perform any task while on UT before it crashes..
