Hi, this is a problem with quite a few 5.1.1 roms and it's not just cm based. I also had this error with the latest Chroma rom. Your idea to edit the updater-script was a good one but that's not the problem. You need to replace the update-binary, which is located in the same folder.

For CM, you need to replace it with the last known CM 5.1.x rom that you are able to flash. It doesn't appear to work with an update-binary from 5.0.x, it has to be 5.1 or greater.

In your case, just replace the latest Candy rom update-binary with the one from Candy 2.0. I've already done this with Candy 2.5 and it works.

Just an FYI to both of you. Flashing the rom is just half the battle, some of these 5.1.1 roms will boot and some will not unless you flash a custom kernel over it.

I'm using Bricked kernel for its kexec patch on my primary rom and some 5.1.1 secondary roms have booted, while a couple of others failed to boot unless I flashed Bricked kernel over it.

It's been purely hit and miss for me. For example, on my first flash of Temasek's cm12.1, it failed to boot without a custom kernel, later I flashed an update of the rom without a custom kernel and it booted???

Btw, Candy booted fine without the need to flash a custom kernel on the first try.

Well, good luck to both of you. LP 5.1.1 has been wreaking havoc with multirom, hopefully the master Tasssadar will be able to make the necessary fixes. :D

Hi to all,

I don't have the ROM type option "Ubuntu" in Advanced-MultiROM-Add ROM.

Why?
[Nexus 7 Original Development] PinoDG:
hi friends

these errors are also on my tablet n7 3G ... I found that the partition "system" has a capacity of 0,00MB ... this fact does not install properly busybox as "persistent" in ROM primary ... how to solve?

how would i go about updating the stock android rom 5.1 to 5.1.1 if i am using MultiROM?

im using other roms too.
[Nexus 7 Original Development] Maxr1998:
Just flash in Recovery or via fastboot. Just don't forget to remove the wipe flag in fastboot (or just flash only system).

[Nexus 7 Original Development] The Letter M:
if i want to do it with recovery, which files do i use? do you have a link?

thank you.
[Nexus 7 Original Development] Maxr1998:
Well, you basically need a flashable zip of stock 5.1.1…

After quick googling, I sadly haven't found one here on XDA or elsewhere, so I highly recommend flashing it with fastboot.

Get the factory image zip from here, then extract the system.img from it, and flash it with "fastboot flash system system.img".

Then reroot it with SuperSU 2.46 via recovery ;)

EDIT: Possibly 5.1.1 has a new kernel, so also do "fastboot flash boot boot.img"!

I'm still having the problem where ubuntu desktop does not boot because of F2FS filesystem (that's the shown error) BUT when I go to recovery to check on the filesystem I find it to be EXT4..... So what now?

Another thing, it says in the OP that ubuntu touch is available from within the app but actually it's not, just a reminder.

twrp error to install

Hi [MENTION=452513]tassadar[/MENTION]

too many ROM and zip file are not accepted by TWRP to install.

Please control the log attached?

.... Thanks for your great work !!!
[Nexus 7 Original Development] The Letter M:
yeah this is a problem, we cant seem to install any new roms cause the recovery doesnt allow it.

[MENTION=452513]tassadar[/MENTION] please fix.
[Nexus 7 Original Development] WooHooGuy:
Current version of modified TWRP overwrites primary ROM instead of adding a new ROM. I went to add Omnirom and it overwrote the primary ROM, gladly I had a nandroid to start over.

I reverted to Multirom TWRP 2015-02-12 V2.8.5 and the secondary ROM installs just fine.

/fyi

Edit - I should have provided a link to previous versions, you can roll back here via Basket - https://basketbuild.com/devs/Tassadar/multirom/grouper
[Nexus 7 Original Development] RusherDude:
I didn't have that problem, the new ROM added correctly and primary wasn't touched at all, using current TWRP modified version.
[Nexus 7 Original Development] Tasssadar:
New recovery update fixes flashing of CM-based ZIP files. They changed their update-binary so that it checks something nobody else does. I'm kinda surprised this didn't show up on other devices and just grouper, interesting. Anyway, sorry for this taking so long to fix.

F2FS and MultiROM

i just want to ask.

i've been using ultirom for sometime now..and i have experienced its worst bug that you can't restore nandroid backups. But that's not my main concern now. i want to know if i can use a part-F2FS (not full F2FS) setup for my primary ROM? been using Optipop ROM by [MENTION=5373714]freak_97[/MENTION] because it's the fastest lollipop rom for grouper to date.:D and a friend who's also an N7 owner is using his Optipop on part F2FS (data and cache partitions converted to F2FS) and he told me optipop is a lot faster still..so i'm jealous. but i couldn't abandon using multiROM as i am using a non-lollipop ROM on my secondary so that i can use Freedom to hack my games.:D so is it possible to do a part F2FS on my primary ROM? hoping for answers.:D :fingers-crossed:
[Nexus 7 Original Development] todivefor:
Was running cm-12.1-20150601-NIGHTLY-grouper. Updated multirom to latest apk. Hadn't been running it in awhile and wanted to try optipop. I had data and cache formatted as f2fs. Ran the update from multirom with cm 12.1 kernel selected. It installed MR TWRP. When it rebooted I was running CM 12.1 as if factory reset wipe which also included media/data (sdcard). Any idea why this would happen?

It was the rom made by timur a while back for nexus 7 (grouper) been running that since then when I installed my tablet in my car. Think it was 4.3 (based off cm10.1).
[Nexus 7 Original Development] albenex:
I've been using MR for years but yesterday i switched to F2FS on my Tilapia (formatting to F2FS /system /data /cache as different guides suggested)

and now i can't make any secondary rom work.

Flashed MultiROM TWRP (2.8.6), at first successfully using f2fs-patched SlimKat rom as primary but even using f2fs-kexec kernels, MultiROM menu didn't show at boot. I managed to view this menu by using LegoF2FS and M-Kernel#69 but both didn't boot neither on primary rom (slimkat) or secondary (another slimkat).

Afterwards i tried as primary AutoDroid 4.4 , Resurrection Remix LP , AICP LP but more or less same result..

my best result is that i can boot only primary rom but didn't managed to have 2 different (or same) ROMs.

Am i missing something?

any help would be appreciated, thanks!

So is there a way to share apps between roms? I'm using stock (5.1) and dirty unicorns (5.1.1) and I don't want to have to download everything on the second rom again. Thanks the setup process was a breeze and it even looks nice!

Apps or their data can't be shared. Titanium Backup helps setting up the secondary and is good for syncing app data.

This wakelock drains a lot of battery when the device is in standby :(

Is there any working kernel compatible with slimkat (And all-f2fs partitions) as a primary? I tried the 4.4 M-Kernel but it says "doesn't have kexec-hardboot patch!"
[Nexus 7 Original Development] pcz:
Hi Tasssadar.

Thanks for your development! I have a question, are there any way, to use the main rom with a different kernel? I mean I want to use as a main rom a rom which have no kernel with kexec. As a second it is no problem, but can I use it as main without to loose multirom?

An another question, Sometimes I facing, that I can't install rom as a second, which have big size (I tried to usb and internal as well, and I have enough free space).

E: WARN: Modifying the real ZIP, it is too big!

E: The ZIP file is now unusable for non-MultiRom flashing!

What is the limit of the installer size? Are there any way to use/install these rom's as a second.

Thanks a lot

wrong thread post
[Nexus 7 Original Development] theFume:
So I have a question. First let me comment that I am not using a nexsus 7, but this I believe is the origin of mulirom and my question isn't a porting issue but a basic understanding of multirom. I am currently using a LG G3. Now for reasons I won't get into here, I need a ROM that's stock, unrooted on my device. I have multirom set up to boot such a rom as my daily driver as well as a secondary. Now I'm OK with stock, but I want to remove some sock apps. So I would like to access my Stock rom while in my secondary rom, which is rooted, and delete some apks.

Is it possible to access other rom's filesystems while in the currently booted rom? If so, how would I do this?

Edit:

... nevermind found it "readata", right?
[Nexus 7 Original Development] jarari2:
Maybe I should be more specific :D

I tried to browse files in /sdcard/multirom/roms/MIUI/data with Root Explorer, but I couldn't see any files.

So I opened terminal and ran "ls" on that folder, and I got Permission Denied message.

What should I do to get access for this folder on N7 android?

If there's no way, then I'll just download ubuntu img :D
[Nexus 7 Original Development] Tasssadar:
Use root explorer and go to /data/media/multirom/roms. N7 does some permissions-related magic with files in /sdcard, so ROMs might not be visible from there.

That's a problem of the Ubuntu developers, it's a testing OS right now so don't expect a perfect smooth and fast OS, as example touchscreen stops to react after a few minutes on dash, firefox doesn't like touchscreens and nautilus doesn't open folders on double tap :P

Ubuntu team released an updated 13.04 yesterday as well. I think they got the video back to useable.
[Nexus 7 Original Development] O2Blevel:
Downloading it now. 12.10 gave me a lot of problems. Do you know if in 13.04 folders can be opened in nautilus, I couldn't do that with 12.10?
[Nexus 7 Original Development] rebel1699:
Not sure. I have not installed yet. I could open folders in12.10 using a mouse with double click most times. Other times, it was a pain. I am probably going to wait on Tassadar updates multirom for compatibility with 13.04 before I move up to it.

Skyrocket on AOKP by R4ins
[Nexus 7 Original Development] O2Blevel:
I'll probably give it a try tomorrow. I've always used the internal kernel, although from what I understand the ROMs using the linaro toolchain really show off their stuff with a kernel also using the linaro toolchain. So that's something I may try after multirom gets updated.
[Nexus 7 Original Development] O2Blevel:
Well, I loaded 13.04 and it seems to be quite a bit more responsive and usable. But I still can't get folders to open in nautilus and wifi didn't seem to be as sensitive as 12.10. Couldn't do a lot with it since my battery needed to be recharged, so I'll take another shot at it tomorrow.
[Nexus 7 Original Development] fr8cture:
So how do we update it? Just reinstall in twrp? Does it replace the old install? (Ubuntu)
[Nexus 7 Original Development] O2Blevel:
I don't know about updating ubuntu. What I did was delete ubuntu 12.10 in twrp and then install 13.04 using the same procedure as before. Seemed to take a little longer this time, maybe I was just a bit more anxious this time.

Ignore the quote of myself posted below this. I was wrong and horribly mistaken as evidence by everything falling apart after reboot. Tassadar is a genius, I'll just say that much,
[Nexus 7 Original Development] farmerbb:
ericdjobs, thank you so much! I was literally just trying to upgrade to 13.04 myself with MultiROM, and failing in the process! I will use your images then!

By the way, if anybody's stuck booting in Ubuntu because of these incompatibilities and can't reboot back into the MultiROM menu, use fastboot to flash an Android kernel, then immediately reboot into recovery and "inject current boot sector". Then reboot and you should be able to select your internal ROM.

TWRP Not showing Ubuntu option

Hi everyone!

I have a Nexus 7 2013 and I'm looking to try out Ubuntu desktop 13.04

Problem is that in TWRP the option for flashing Ubuntu is abscent so I'm wondering If I can flash the Grouper TWRP linked in this post...any help will be thanked!
[Nexus 7 Original Development] GuyInTheCorner:
Don't flash Grouper TWRP, you're more than likely to break your tablet due to it being a grouper image. If I remember correctly there's an option in MultiROM manager to flash Ubuntu?

Yes, there is Ubuntu...but it's Ubuntu Touch. I need the desktop version as I want to code on my tablet....may not be the most power efficient way to do it...but I guess it'll get the job done, As far as progress go, I wasnt able to do much...I tried everything but I just dont know what to do...

I've downloaded "ubuntu-13.04-preinstalled-desktop-armhf+nexus7.img.gz" and placed it in internal sdcard

and I have 3 option (Android , *.mrom and sailfishOS)

any help how to add Ubuntu desktop ???
[Nexus 7 Original Development] z31s1g:
If I remember correctly, the option to install Linux desktop was ditched in favor of Ubuntu Touch more than a year ago. Then UT installation was moved to the MR app, and Sailfish OS was added in the recovery menu, replacing the UT installation option.

So installing Linux Desktop on a Grouper via Multirom isn't possible any longer, only full installation (replacing android).

But then again, I played with Ubuntu Desktop when support in Multirom was still present, and I found it nowhere close to usable for being used productively (or at all tbh).
