Ubuntu Touch is not available for this device.

Hi all, there are a lot of ppl complaining that if you launch the MultiROM Manager app on a Nexus 7 2013, it says down the bottom that Ubuntu Touch is not available for this device. I dont have a 2013 model, but can you tell me which models of Nexus 7 is this app working on?

Glitch kernel has same problem flashing into secondary ROM. Black screen and no change to kernel.
[Nexus 7 (2013) Original Android Development] rifraf1:
Seems as if both the glich and elementalx kernels will not flash on secondary roms, they both use aroma as the installer. Was experimenting and tried to run the abootimg utility on my N7 to try and create the boot.img file but got a size mismatch error or something like it. I did notice that the zimage files for the 4.4 kernels are much larger than the 4.3 kernels could this be the problem? Does multirom have a problem with a larger file? :confused:
[Nexus 7 (2013) Original Android Development] GialanG:
It depends on whether you choose Share or Don't share kernel. The kernels work perfectly if you don't share with internal, you can simply install .zip files and run aroma as usual.
[Nexus 7 (2013) Original Android Development] wd5gnr:
Nope. This was with unshared kernel.
[Nexus 7 (2013) Original Android Development] bbernardini:

Hi [MENTION=3418703]Tasssadar[/MENTION]

I'm thinking of installing this. but one thing I noticed was that the TWRP in the OP is 2.6.3.0, while the latest TWRP is 2.6.3.1... are you planning on recompiling the recovery anytime soon? Then I might wait for you to do that. ;)

Also, wanted a bit of a clarification... Let's say I keep AOSP as my base, and I install CM11 on MultiROM... what kernel will the CM install use? Will it rely on my AOSP kernel, or use the CM kernel bundled with the ROM?

Edit: No need to answer that second question. Noob me. ^_^

Can I wipe /system partition of the secondary rom? I want to change gapps from PA gapps to BaNkS gapps so I have to wipe the /system partition of the second rom
[Nexus 7 (2013) Original Android Development] xanthrax:
as far as i can see on the second ROM options there isn`t any posibillity to do that

anyway , after system wipe you need to flash a ROM so , re-flash the ROM because during the process the system will be wiped

afterwards you can go to advanced/multirom and flash your new gapps
[Nexus 7 (2013) Original Android Development] stfudude:
Correct me if I'm wrong but Omni rom does have backup script in /system which prevented those gapps I flashed from being wiped during dirty flash of the rom. That's why manual wipe of /system is needed.
[Nexus 7 (2013) Original Android Development] xanthrax:
yes , you`re right , without system wipe you`ll end up with the same gapps

you can flash the new gapps on top of it but no guarantee , it should work fine but still some libs will get messed up

also , you can open the ROM zip and delete the script

system/addon.d folder and delete 50-hosts.sh

save both zips , the original and the modified one and the script as well

I have a problem. My primary rom is the stock KOT49H rom while the secondary is omni rom. I think I might have flashed a gapps zip on the stock KOT49H. Now I can't boot to the primary rom. After wiping dalvik and cache, the screen stuck at "starting apps".

I think the solution is to flash KOT49H factory image without "-w". I got an error saying "partition table doesn't exist" after running the command "fastboot flash update image-razor-kot49h.zip"

Please help.
[Nexus 7 (2013) Original Android Development] xanthrax:
hmmm ... yea , you flashed a wrong ROM ...

which device do you have , deb or flo ?

FLO , sorry

you need to flash a stock or cwm recovery , it doesn`t work through the twrp modified

[Nexus 7 (2013) Original Android Development] xanthrax:
yes you can

then , if all goes fine , you can reflash multirom recovery or easier use the app and boot into your sec rom

in there you can backup your apps using TB , the backup folder will be updated and recognized by any rom

Since my tablet can't boot and I have uninstalled MultiROM, how do I transfer stuffs to my tablet?

My last resort would be to factory reset (without formatting /data/media) in normal TWRP then flash the factory image again. Yeah I know how to flash the factory image, thanks for reminding.

If, somehow, I managed to fix the primary rom, I plan to restore the secondary rom from a nandroid backup that I have made prior to uninstallation of MultiROM, but I didn't find an option in modified TWRP to restore the nandroid as a secondary rom. Could you tell me how?
[Nexus 7 (2013) Original Android Development] xanthrax:
well , without multirom and the modified twrp there is no chance to restore as secondary

i suggested you to flash the normal recovery in view of flashing via fastboot of the factory images

you should have on the downloads folder of twrp the multirom zips and you can flash them to get the multiboot

use adb to push the zip in your device and then flash it

TWRP has been updated to 2.6.3.1
[Nexus 7 (2013) Original Android Development] stfudude:
MultiROM v19 just released. Changes in recovery:

12.15.2013

=====================

* Support OTA updates on secondary ROMs (tested with omni)

* Add "Swap ROMs" feature

* Implement "boot the last ROM" auto-boot type

* Many bugfixes

I'm more interested with the bolded one because yesterday I've messed up my tablet again (sorry, I derped again) by selecting "flash now" in OpenDelta (Omni rom updater). The recovery flashed omni rom zip file onto my primary rom (which is stock KOT49H). It's nice that Tasssadar have now fixed this issue. Can't wait to flash the next nightly with Open Delta!

Edit: need to bump my question again.. Can I update the stock rom like usual (by OTA update or manual fastboot flash of the factory image)? The stock rom is my primary rom.
[Nexus 7 (2013) Original Android Development] Tasssadar:
Stock OTAs will not work, as they won't with most rooted and modified devices. OTAs contain only the bytes which were changed since the last Android version, which means they can't be applied to files which were changed in any way, and OTA updater checks for that.

Fastboot should however work just fine - extract system.img and boot.img and flash them like this:

fastboot flash system system.img
fastboot flash boot boot.img

Flashing boot will of course remove MultiROM and your current kernel from it, so you'll have to flash them again - you can use the Manager app for that, flash them yourself in the recovery or just go to Advanced -> MultiROM -> Inject curr. boot.img in recovery.
[Nexus 7 (2013) Original Android Development] stfudude:
If I flash MultiROM uninstaller (after backup of secondary rom), flash stock recovery and stock kernel, then restore every modified files (for example debuggerd and thermald), the OTA will proceed, right?

[Nexus 7 (2013) Original Android Development] cinco312:
You can use a USB flash drive which you will need a OTG cable. That's the purpose of this, you can install as many ROMs your memory can fit. Just don't share the kernel.

how could we install OTA then?

Hi Tasssadar,

I am having this Nexus 7 2013 LTE (deb) running stock 4.4.

Multirom has been installed with the app downloaded from Google Play, currently updated to v19.

I have receive 4.4.2 OTA update for a while but no clue how to install.

Basically if I proceed, it will just reboot to recovery and install by itself with a fail.

In the log, it said something like 'this zip is for deb, but it is a flo' and thus it refused to install.

I am guessing this is because the recovery thinks it is a flo instead of deb, right?

Can you give me a hint on how to fix this?

thanks a lot!
[Nexus 7 (2013) Original Android Development] xanthrax:
if your stock room is primary then it contains a patched kernel kernel in order to have a multirom working thus the OTA fails

from app interface flash the stock kernel and try again

also, be sure that you don't have any mods flashed over the rom otherwise it will fail again

I've made flashable ZIPs with stock ROMs again. These are made from 4.4.2 KOT49H factory images, no changes, no root, no anything. They install just like any other ROM here on XDA though, which means you can use it to flash stock as secondary ROM in MultiROM. They can also be used to upgrade existing stock 4.4.x ROMs.

Thanks for MultiRom! have it working nicely on my 32gig FLO. I have the stock kitkat rom as my internal rom (with elemental kernel), CM11 as my 1st internal and pwned pad as my 2nd internal rom. Works very nicely and I have had no issues to this point once I figured out how it all works.

I do have one request/question though.

There is a "backup" feature for the secondary rom but no "restore" for this. Can a restore be added? Or am I missing something?

When trying out a new rom add on (such as pwed pad onto CM11) It would be nice to be able to backup the original secondary rom and be able to restore it instead of deleting it and starting over each time.

Thanks again!

Second issue is that the boot screen does not remember the last ROM and will always boot to the internal if I do not change it.

Otherwise I think this is the best thing on my N7. Thanks.
