Changes in testing version v26s:

fix franco.Kernel breaking boot of secondary ROMs on some devices

fix "no files on /sdcard" bug in Android L preview (do NOT run restorecon manually on /data/media, it breaks MultiROM.)

fix separate radio.img with Android L secondary ROMs

bunch of crash fixes

If everything goes well, this is the last test version before v27 release.

I have a question on secondary roms. When I install a rom it will download my backed up apps including MultiRom. Can I safely delete it or will it delete the main MR/TWPR?

[Nexus 7 Original Development] physwizz:
I've never had a problem with this. Deleting a secondary rom shouldn't affect the primary at all.
[Nexus 7 Original Development] dareino:
no what I meant was, deleting MR from the secondary rom. You know how google d/l your backed up apps....MR installs on all my secondaries so my question is. can I safely delete MR from each ROM!

d
[Nexus 7 Original Development] physwizz:
You can delete the mulitrom app from each if that's what you want to do but that won't actually delete multirom. It won't affect the mr app on the primary. Multirom can exist without the mr app. The app is just a convenient way to access some bit of mr and twrp without rebooting..
[Nexus 7 Original Development] Tasssadar:
So, I've bought the flashdrive (big thanks for donation to Gösser Märzen), but little problem appeared - flash drives normally use acient, slow, feature-less FAT32 filesystem, because it is compatible with basically everything. But FAT32 can't handle user permissions, which means I have to use disk image with extX filesystem to store ubuntu or android on the flashdrive.

But FAT32 also can't handle files bigger than 4GB. Considering the fact that clean ubuntu takes ~1.5gb of disk space, 4GB seems kinda low.

Basically the only option is to format the flash drive to NTFS and use images to store ubuntu & android. If I wanna keep the flash drive compatible with Windows computers, that is.

I'd like to just make another partition on the flash drive with extX filesystem, but Windows can't handle flash drives with more than one partition. Welcome to 2012, guys.

Hmm, this is kinda awkward - I thought I'll have several options how to solve FAT32 options, but during the writing of this post I figured that NTFS and images is the only option. Oh well, not gonna delete that now, at least you'll know why you'll have to format the flash drive.

I've already fixed that in source code, will be in v3. Thanks :)
[Nexus 7 Original Development] bonzer2u:
Would exFAT be a possible alternative???

http://www.microsoft.com/about/lega...rty/iplicensing/programs/exfatfilesystem.aspx

it is supported in xp/2003/7/2008/8.....

http://support.microsoft.com/kb/955704
[Nexus 7 Original Development] Tasssadar:
I don't think exFAT is supported by android.

And well, dammit - NTFS support is in android kernel by default, but only read-only (wait, what?). I'll have to use FAT32 and allow you guys to use patched kernel if you want to have images bigger than 4gb :/
[Nexus 7 Original Development] jarari2:
Hi, I injected franco kernel's boot.img but the kernel for Internal doesn't change :(

Any thoughts plz?
[Nexus 7 Original Development] seahorsepip:
Why not just simply use ext4? you can add a format usb as ext4 option in the boot menu under misc to make the whole thing easier too :P
[Nexus 7 Original Development] Tasssadar:
You have to inject it and then flash it, or flash it via fastboot and then choose "Inject curr. boot sector" in recovery.

Because Windows. I wanna keep it compatible. I'll probably let you choose what you wanna do, though - FAT, NTFS or ext4.
[Nexus 7 Original Development] ratcav:
Well, with ext2fsd you can see without problems ext4 partitions on windows!
[Nexus 7 Original Development] Raudi1:
But you have to install it on any computer you want to use it on.

Would it be possible to enable NTFS or exfat support on the nexus 7 or any other Android device running AOSP?

That would make the usage easier than adding ext4 support on all windows machines.

But since I use Linux on my laptop anyway, I would prefer ext4 over FAT32

The best solution would be for microsoft to integrate ext4 support, but that will probably remain a dream...

Hi, I'm having a problem with flashing the multirom .zip in recovery. It fails the flash with 'status 7' and says something like buildprop.device == "grouper". I'm on a 32gb 3g model.

Has anyone else had this problem?

Thanks in advance.

EDIT: I managed to write down the exact error :

Assert failed: getprop("ro.product.device")== "grouper" || getprop("to.build.pr

The rest is cut off.

EDIT 2: Solved it. Edited the updater script myself to match the correct device.
[Nexus 7 Original Development] Tasssadar:
Yeah, it checks if it is grouper, I forgot to change it to accept also 3g nexus. Kinda interesting other people with 3g nexus did not have this problem. Anyway, can you tell me what this command says when you run it in root shell on your 3g nexus?

cat /system/build.prop | grep ro.product.device

PS: I've just booted cyanogenmod from flash drive, looks like there is no problem with it. Good night :)

I'll let you choose - if you have kernel which can handle ntfs, you'll be able to use it. If you wanna format flashdrive to ext4, by all means, do it, MultiROM will be able to handle it.
[Nexus 7 Original Development] bonzer2u:
Excellent, my preference is for NTFS if it matters........
[Nexus 7 Original Development] zamps:
The response is

ro.product.device=tilapia

# ro.build.product is obsolete; use ro.product.device.
[Nexus 7 Original Development] Raudi1:
Probably because many of us are running a grouper recovery.
[Nexus 7 Original Development] Xentar712:
I've been installing my Roms manually to get around the tilapia block. There also haven't been any tilapia roms made yet, so I've been installing grouper ones(with no 3G) instead. Probably risky on my part.

---------- Post added at 10:44 AM ---------- Previous post was at 10:42 AM ----------

Exactly, and the only rom is Modaco, which works fine on a grouper recovery(at least it did when I flashed it). When flashing the 4.2.1 stock update though, I got an error, so I had to flash through fastboot.
[Nexus 7 Original Development] Raudi1:
I'm also running the Modaco rom with a grouper recovery. Didn't even try the stock 4.2.1 update. It will have to do before Cyanogenmod becomes available. Then I just need a way to dualboot it with Archlinux and I run all my favorite distros on one device :)
[Nexus 7 Original Development] Xentar712:

How can I get access to data folder of other roms?

It says permission denied everytime I try to see files inside :(
[Nexus 7 Original Development] rebel1699:
Open a terminal, and type su. Enter password (ubuntu). Type "nautilus". When nautilus opens, browse all the files you want, including the other roms, including internal.
[Nexus 7 Original Development] jarari2:
Thanks for the reply! :)

Then I need ubuntu, right?

Could you tell me if there's any way to access the folder with the device itself please?

Cuz I don't have computer :P
[Nexus 7 Original Development] rebel1699:
Well, you need ubuntu on the n7, yes. You can also access roms from wothin android in the sdcard in "multiboot" folder.

I was running 4.4 as internal and L as secondary, through multirom.

Today I decided L is stable enough for me, so I wiped 4.4 (internal) and flashed LPV81C from the zip file here: http://xdaforums.com/google-nexus-5/development/rom-n5-l-developer-preview-t2796003

I selected the "Inject MultiRom after installation" but the install failed, so I tried again without the option, and it worked.

Problem is, now I can only boot in the new internal L ROM.

When I try booting the old external one (need to get some data from it), it does not work: it gets stuck at the initial "Google" boot screen for a minute or so, then reboots itself in recovery.

Any ideas? I just need to get some AppData from the old secondary rom, then I can wipe it.

Thanks

I could only find the full installs for razor and hammerhead but not for grouper.

Did you reinstall the kexec patched kernel or did you leave kernel that installed with L? Also try reflashing MultiROM again.

I had to downgrade to v27 from v28. Certain apps were conflicting, no issues anymore. Working great.

How can i enable Ubuntu option?. ( Want to install Ubuntu Desktop 13.04 )
[Nexus 7 Original Development] Dude360:
Just a quick question.

Finally got round to playing with MR and loving it, awesome piece of work!

Right, so, I have a theme on TWRP. When in normal recovery this theme is there.

On occasion when I finishing flashing a zip, TWRP will reboot and I will be in a TWRP without a theme.

Q: Is this themeless 'area' the TWRP relating to the new ROM/zip Ive just flashed and will anything I flash be sent to the normal ROM or the secondary ROM?

I dont know if this is a feature to show Im controlling/in a different ROM, or if its a glitch with the theme or TWRP

Ive been rebooting back to normal TWRP (where theme is on) then using the MR button from there and flashing.

[Nexus 7 Original Development] USBhost:
First off you cant be f2fs and ext4 at the same time

That being said

If your installing an none coverted ROM

You will have to share kernel because the kernel in that ROM

Does not support f2fs, well at least the RAM disk doesn't

So

For it to boot you need to share kernel

Or

Flash an f2fs kernel

Restore Architecture

Just curious as to how the restore structure works with MultiROM [MENTION=3418703]Tasssadar[/MENTION]?

EG: 1 is primary, 2 is secondary, 1r is primary nandroid, 2r is secondary nandroid

Restoring 1r would restore 1?

Restoring 2r would restore 2 while not affecting 1?

Backup of 1 results with remnants of 2 backed up as well?

Backup of 2 only backs up 2?

Because I tried to restore 2r on main subset of TWRP due to a lack of a Restore button under Advanced>MultiROM and it always fails to restore!

Thank you!

Been using a Nexus 7 since 12/2012, and Multirom shortly after, and would like to say (again perhaps):

hello i am trying to flash the android l preview using multi rom but when i go add rom in multirom recovery. i dont have the option to "Share kernel with Internal ROM?", it just has - "Choose ROM type" - "Android" and then install to "internal memory" . did that option get removed in the later releases of recovery?

go where you would flash something to your external ROM

AOSP Lollipop as secondary....

As always (in other devices) a huge thank you to Tassadar for MultiROM.

Installed this latest version of Lollipop AOSP Vanilla ROM from "bshiznit", as secondary: Vanilla AOSP 5.0.0_r2 ROM (LRX21M) for WiFi Nexus 7 (2012) Grouper. The install was extremely easy and basically effortless. SuperSU included.

For anyone wishing to try the latest Lollipop version, this might be the one. I personally think that It really works great. See what you think.

Takes a long time on first boot, but after installing my apps and rebooting I found that it is totally normal and it works. Very nice, very very snappy, and as far as I can tell, again, everything does work..

Plz excuse if this ROM has been mentioned here before, I searched and couldn't find anything in this thread referring to it. :good:
[Nexus 7 Original Development] blambo:
Please excuse if this has already been answered.

Backup R1 only in TWRP normally. Backup R2 in TWRP (Advanced) MultiROM. Two completely separate entities.

To restore Backup of '2' as your secondary:

In MultiROM TWRP: Go to 'Advanced', then 'MultiROM', then 'Add ROM', make sure 'Android' and 'Internal memory' are selected (they are by default), click next, then choose 'Backup' as the source..

Note:

If you already have a ROM as secondary, you may want to delete it first before installing the backup. When the backup is installed, it will then appear as your normal secondary. This method does not overwrite the secondary, it adds another ROM, but it creates it from your 'R2' backup. Be aware that it does take a good while to restore the secondary backup, but it works flawlessly.

Hint: Rename the secondary ROM from its backup name to its original name in 'MultiROM Manager'.

Play with this a little, I think you'll find the method very well thought-out and the reason why Tassadar made it this way. Brilliant actually. :good:
[Nexus 7 Original Development] Tasssadar:
Stock 5.0 zip files from LRX21x, get 'em while they're hot! Clean, mostly unmodified, not rooted ZIP installation files straight from factory images. They have the "kernel modification" needed for SuperSU in them, so the only thing you need to do to get root is to flash the UPDATE-SuperSU-vXXX.zip file.

Basketbuild or dev-host, files starting with lrx21. If your device isn't there, then the factory image was not yet released.

Kernel sources are out too and I'm building patched stock kernels right now. From what I can tell, final 5.0 images work just as well as the preview ones did with MultiROM.

Instead of installing the zip as a new rom, I used TWRP to create a copy of internal and then flashed the zip into this copy so it used it as an update. This gave me an updated secondary rom running Android 5, and now wifi works, yay!
