Zsync is a utility for linux that downloads only the

changed parts from the repository and builds an ISO. You should download the standard .iso.gz file for installing and then just run updates.

You don't need to unzip the image, just install it as-is in recovery. Make sure you have updated your recovery to the latest version.

OK so how and when do you use the patch Kernel ?, I installed the MultiRom .zip and also the updated recovery . I put the ubuntu .img.gz file on my USB storage boot into recovery select a MultiRom-Add Rom select "Ubuntu" the plug my USB in press refresh, i then see- /dev/block/sda2 (vfat) which i selected then press next, i then see "root.img:4095 MB and a button saying "Change" and next at the bottom i select next then try to choose external SD to get the "Ubuntu file from it but it won't allow be to select "external SD" . Does this mean i need to be formatted to fat32 or i need the Kernel ? . Also i have Miui rom in MultiRom on my SD when i had V2 installed but i'm not seeing it , i deleted Ubuntu because i was planning on installing a fresh 13.04 .
[Nexus 7 Original Development] bonzer2u:
I installed it 3rd on the list after the multiromV3/recovery. I believe you have to install the patched kernel prior to installing ubuntu or any other android version that does NOT share the same kernel that is running on your N7 prior to installing dualboot.

I installed on internal memory and everything went as Tass suggested it would, about a 10 minute install.

Just saw that bodhilinux has been ported to Nexus 7 as well. Any plans on it being supported in a future version of multirom? This is not a request, but a general curiosity. Bodhi looks really good for an alpha. Scrolling home screens like android.

Yeah that's how i installed it on V2 but one of the features of V3 is the external storage where you can use USB to install Ubuntu that's what i'm trying to do but it's not allowing me to select external storage,i have a 32 GB USB which would be great help with space for my 16 GB Nexus7 . So you installed the Kernel patch after you install roms in Multirom and also after you install your internal rom ? .

kernel ready for testing :)

Hi guys,

As requested, here is my kernel with the added patches (see my commit here). This is simply my build 244 + the kexec-hardboot patch with all options enabled via the config.

motley build 246 (446 GPU) with kexec-hardboot support: View attachment 1577503

Note: this is my standard AnyKernel zip without the ramdisk. I haven't studied this thread yet to understand how it all works. If you just need the zImage and want to do something else with it, it's in the zip file. I recommend that someone with experience tries it first and then reports back.

Let me know if it works as expected for the boot process. I see no ill-effects from the Android perspective thus far, except that we lost 1MB RAM:)

Thx,

motley
[Nexus 7 Original Development] Rafase282:
I can confirm that it works. I flashed it like a regular file, then booted into CM10.1 then into Ubuntu, works great.

---------- Post added at 03:01 AM ---------- Previous post was at 02:51 AM ----------

I installed it. When I tried to boot it asked for

commands.

It also complained about a missing /sbin/init.

To get to the files you need to get into recovery and use adb shell. I'm trying to see if I can get it to boot.
[Nexus 7 Original Development] rebel1699:
Nice! Are you installimg through multiboot or via fastboot in the normal fashion?

Tassadar- Since usb is now supported, i have noticed that you have been referring to flash drives. Is it possible to use an external hdd? I have a 160Gb that I would like to partition and use for a much bigger ubuntu installation. I would simply try on my own, but this hdd has no external power (usb powered) and would like to know for sure before I splice power into the cord. Thanks again.
[Nexus 7 Original Development] rebel1699:
SUCCESS! I wired a 5v power source into the cord on my wd1600me-00 external hdd (160 Gb) and succesfully installed android. Rasbeanjelly to be exact. It runs surprisingly fast. I thought it would be slow. I was wrong. Amazing! Ubuntu is next on a separate partition.

[Nexus 7 Original Development] Tasssadar:
It is based on Ubuntu, so it will be sooner or later compatible (probably?), right now I don't feel like making support for this distro is needed. That UI is called "Enlightenment", or "e17", it should be available as Ubuntu packages.

If you wanna install the .img(.gz) file from USB drive, it must be on FAT32 partition, and that must be the first partition on the device - I just didn't want to rewrite half of the recovery. Or you could just push it to the internal memory for the installation, it is just 600mb or so.

Hard drive is basically just huge flash drive from MultiROM's viewpoint, so as long as N7 can handle the power requirements of the HDD (or if you have additional power source), it should be okay.

I mean the file which is in /tmp/recovery.log. But, I can probably see what is wrong - the recovery is just for grouper, and cannot handle tilapia ZIPs. I've just released new recovery, which should be able to handle both, more in this post.

--------------------------------------------------------------------------​

New recovery released. The TWRP is updated to the newest 2.3.3.whatisthatnextnumber, it should be able to flash ZIP files for both grouper and tilapia, and - you can now "Add ROM" from backup. It simply restores the backup as a new ROM.

PS: I am getting really lot of PMs, usually asking what to do when something does not work. I don't like that. I am not that person. I can handle like a few, but seriously, this is forum. You as the community can solve most of the problems yourselves. And that you can post here yet is no excuse - just create thread in general, Q&A or something.

So "Tasssadar" the reason i can't switch to external is because the USB is not Fat32 ?. I installed Ubuntu on the the Internal memory but i would love to use the USB, i bought a dongle just for that .

Boot ubuntu on your N7 and insert your usb stick. Open app called disks. Format the stick to ext4. Reboot and install any os you choose to the stick, without mem limitations.

[Nexus 7 Original Development] Tasssadar:
Yeah, sorry, I did not test it with backup in internal memory, because I kinda am starting to have problems with space on my 16gb nexus :/

So, new recovery with fix: http://www.mediafire.com/?gno3g62akkezt6t

We probably do not understand each other. The location where you want to install ROMs is selected on the first screen, right after you tap "Add ROM" - in the lower part, it is called "Install to:". Your flash drive should show up there (as /dev/block/sdaX (filesystem)).

When you're on the screen where you select the Ubuntu image ("Select Ubuntu image file:"), then the image file must be either in the internal memory or on usb drive with FAT32 filesystem.

So, you can install to eg. ext4, but the installation image file you download must be in internal memory or on FAT32 partition.
[Nexus 7 Original Development] jawonder:
Tasssadar That's what i'm saying , i did all of that select the location for install choose the /dev/block/sdaX/ and i have the Ubuntu file on the USB but i'm not seeing and it . After choosing the dev/block/sdaX/ it seem to still have the blue dot checked on internal . So i move the Ubuntu file to my internal SD but it won't allow me to select external for installation
[Nexus 7 Original Development] Tasssadar:
Okay, screenshot time. When you say "it won't allow me to select external for installation", do you mean those toggles I've highlighted in attached screenshot?

If so, those are used just to select location of the image - if you have it on USB drive, you select "external SD" and it will switch to USB drive and you can select the image from USB.

Toggles like that are used throughout the recovery, so I thought it would be okay If I used them too.
[Nexus 7 Original Development] shinji257:
Gah... this looks interesting and something I want to try but I can't make heads or tails of the directions. Keep in mind that I can usually follow them. Is there a video that I can watch that allows me to see the install of Multirom visually along with the installation of one rom so I can see it being done? This would help me figure it out. Thanks.
[Nexus 7 Original Development] smirkis:
what don't you really understand?

flash this with your recovery..

MultiROM: multirom_v3_n7-signed.zip (md5 abb2b6242441e9c7531294651c9a2a7e)

then fastboot flash this new recovery

Modified recovery (TWRP 2.3.3.0): TWRP_multirom_n7_20121220-2.img (md5 e9e1cbf6b1f749e2d45c0cadddd198d5)

flash whatever kernel fits your device

Kernel w/ kexec-hardboot patch (4.1.x, grouper): kernel_kexec_41.zip

Kernel w/ kexec-hardboot patch (4.2, grouper): kernel_kexec_42.zip

then poke around and learn how to use it.

this is more like the android hacking i've been waiting for. recoveries/roms is just so basic now days, i'm glad to see this type of development going on. get your hands dirty people, you can't brick your device, if it stops working reflash back to stock images in fastboot and start over.
[Nexus 7 Original Development] jawonder:
Exactly !, those are what i'm talking about . Ok i got what you are saying .

I installed the boot image and recovery, no issues. I then installed Ubuntu to a USB flash drive (the image was also located on the USB flash drive, formatted fat32), which seemed to proceed through all the steps normally. When I rebooted and switched to USB there was nothing detected. My only choice was to boot from internal, the stock ROM I had been running before. I'm really not sure what went wrong, everything seemed to go exactly as it should.
[Nexus 7 Original Development] tiny4579:
Just wondering. I installed the raring image and when it booted it was 12.10. Maybe just an old version listed on the installer.

Problems with my original rom and boot

Hi,

I have N7 Wifi. I donwloaded the ubuntu image from the link posted on the first page cdimage.ubuntu.com/daily-preinstalled/current. The errors.txt file from /dev/block/sda1 is attached.

At first it boots to the recovery always, USB attached or not. I try to fix it running "Inject curr. boot sector" and flashing again multirom and recovery and now it boots directly to the Nexus bootloader and from here I am able to boot to recovery TWRP 2.3.2.3. From this recovery I am able to browse the internal filer and list the rom form the USB in case I have attached it. If I flash the multirom anothe time, then it boot to the multirom but I can not see the ubuntu rom under USB "tag". If I choose "Internal" from the Internal tag and "Boot", it shows "Booting ROM... Internal" but nothing happens...

The USB pendrive contains the raring-preinstalled-desktop-armhf+nexus7.img (667 MB) file and a multirom folder with a raring-preinstalled folder that contains root.img file (4 GB).

Following one of the last post, I managed to boot my ubuntu installation, just unpluging, and repluging the stick. The problem is I can not boot my original android rom. Do I have to do something else to boot my android rom?

Regards,

Any help will be greatly appreciated!!

Thanks in advance...

Can't boot from original internal ROM

Hi again,

I managed to boot from ubuntu and Cyanogenmod 10.1 from my external USB stick. If I made a backup from my original Android system, I can see it on the boot menu (Internal and ROM) but I can not see Internal at ROM list, just the backup. If I choose "Internal" to boot it does not bott, just stop on the "Booting ROM..." and nothings happens.. If I try to boot from a ROM installed from a backup from my internal ROM, it hangs :( Attached error log as required on the message.

Any idea/clue to try to recover my original Android???
[Nexus 7 Original Development] bonzer2u:
I'd be very interested in trying this distro with multirom as well......
[Nexus 7 Original Development] rebel1699:
Well, im downloading now and going to give it a try. Since it uses Tassadars kexec hardboot patches, it may well be possible without alot of problems. My external hdd is already formatted to a 80 Gb ext4 partition that I was going to use for storage, but I will use for test as well. Sould be able to use the supplied kernel by specifying the "don't share" option. It may not work, but ill try anyways. Im not super expwerienced, but know enough to be dangerous. :D
[Nexus 7 Original Development] bonzer2u:
I have stock 4.2.1 and ubuntu 13.04 dual booting now.

If I ran threw the ubuntu install again would it overwrite my existing or create a 2nd version?

If it installed a second version of ubuntu, what would be the best way to scrub my initial ubuntu install and create a fresh install?

Obviously I would like to scrub ubuntu and have the option to reinstall or better yet run plasma instead.

Nevermind, I just went into recovery and deleted it
[Nexus 7 Original Development] rebel1699:
Simply reinstalling would not replace the first, but just create a second. The process for scrapping the first would be to, in recovery, advanced-multiboot-list roms- then choose first ubuntu install and click delete. Then, reinstall as normal. If I get plasma install worked out, ill post process. Wouldnt hold my breath though! :p

I definitely cant figure out a way to install plasma using multiboot. and since I dont plan on wiping my entire device to install it via fastboot, I guess I'll just have to be happy with android and ubuntu. Would have been cool to try, but I wont be doing it just to have to start over and redo my entire system. We will probably have to wait till it is released in a more multiboot friendly manner, like a proper .img file.
[Nexus 7 Original Development] Squarex:
I asked the Plasma Active developer, if it is possible and he replied:

It seems, that MultiROM could support it by just few changes.
[Nexus 7 Original Development] rebel1699:
Yeah, I was thinking about that. I boot from an external hdd, and have an 80Gb partition just waiting for it. I can get multiboot to see plasma by manually adding the fs to the partition, but am stuck at loading the kernel and passing the args. I would like to be able to perm install the kernel adn get the boot lined out. To this point, all attempts have ended id "system is corrupt. System will now reboot" type message. You cant actually "flash" it through multiboot, because multiboot does not recognize tar or tar.bz2 as flashable or installable.

Is it possible to flash via fastboot to /mnt/usb/sda1, for example? (I know that may not be the correct path. Just an example). If it could be flashed to an external device with fastboot, that would save deleting the regular internal rom. If done that way, the kernel and boot would be set up correctly and multiboot would recognize it and could most likely boot it.
[Nexus 7 Original Development] bonzer2u:
I extracted the tar out of the bz2 file, then file/folders 1.2GB out of the tar. Would it be possible to repack this directory structure into an installable .img file with dd?
[Nexus 7 Original Development] rebel1699:
I had thought about that too, but I dont think so. I tried several time to do it, but to no avail. Always a "cannot find rootfs.tar.gz", even though I wrapped the root fs into rootfs.tar.gz before dd imaging it. For all I know, I could have had the structure wrong.

It seems like they are trying to build the os AND package in a full miltiboot solution as well. In my opinion, they should have followed ubuntus lead and made a simple installable image and get the core os going and tested before trying to add all the other things that makes it really over complicated. A simple "blablabla.img" would have allowed people to just install it and help get it going, instead of having to abandon the functional android os to get it. It will cut into how many will actually use and test it.
