hey, look what I found!!

I just reconfirmed something & I wanted to share it just to be absolutely positive. My previous experience was with a similar app called Boot Manager on my HTC Evo 4G. It allowed users the freedom to flash, configure, customize, and utilize several different roms on their device. Before changing roms, in order to save your settings and any "new" apps or changes you made, you HAD to do a nandroid backup, otherwise the next time you selected that rom to boot into, all of that updated "new" information was lost. In short, the boot manager loaded whichever rom you selecteds most current nandroid. I thought this was the same, but in my experience it is not. I bounced between a couple different android roms on my device and tested this out. I found that all of my changes were saved without havoing to do a nandroid backup! I thought it might have been just a fluke, so I tried it several more times, and success!!! Works EVERY time! I am not sure if everybody knows this, or if it's a feature that is common knowledge, but I didn't know it nor could I find it addressed in this thread at all. If anybody has more to add to this or wants to clarify this please do. I appreciate learning more about this fantastic tool. Thanks and I apologize for the lengthy post, I tried to make it as brief as possible while also beiing clear enough to make my point. Thanks again for this great addition to our N7!

Each ROM has its own "space" in memory so there's no need to do a Nandroid restore to switch.
[Nexus 7 Original Development] rydog66:
that is so awesome! I don't have to waste time doing nandroid backups like every day or each time I change 2 little things. I can do backups as needed. Thanks for the reply!

Would you ever consider bringing back multirom cwm?

[Nexus 7 Original Development] rebel1699:
I dont recall there ever being a multirom compatible cwm in the first place, and Ive been here since the first release of multirom.

Regarding CWM: see answer to android1999's question in this post: http://xdaforums.com/showpost.php?p=37457292&postcount=1058

I don't really see reason to use CWM, but if you really need some of it's features, it would be really easy to multiboot it using MultiROM - TWRP would be in your recovery partition, and CWM would be another entry in MultiROM's list.
[Nexus 7 Original Development] Mahdi786:
Hi Tasssadar, just a question, would multi-rom be difficult to port to nexus 4?

Question on a similar note for Tasssadar - what's the next smartphone you're likely to buy and develop for?

It'll help me narrow my choices ;)

Thanks for your work mate!
[Nexus 7 Original Development] Tasssadar:
Again, as I said, I really have no idea. I don't know what exactly is different, it could be a day of work, but it could also be month of work. I just won't know until I try it.

Well, I'm just a student, I'm not even adult yet and I don't have any job, so I don't make any money. Its most likely that I won't get a new phone for quite some time. But if I were to choose a phone, it would definitely be a Nexus phone.

Minor bugfix relase of modified TWRP. It fixes "Add ROM" option, which would not work properly if you use backup as a source and that backup is bigger than 1.5gb. You don't have to update if this problem does not concern you.

Yeah, the actual device is needed. Also, time machine would be handy ^^

OK, getting a Nexus 4 device is a realistic possibility.

I have been talking to Timur, the creator of the host mode charging kernel work. He has been gratious enough to agree to add kexec-hardboot and allow me to test before release (no eta given. Please dont rush him) If you have an acct over on rootzwiki, stop in and give him a thanks and support. It will be a great kernel to add to the multirom arsenal with some killer features.
[Nexus 7 Original Development] rebel1699:
Timur had me test his rom today, which had the kernel baked in. Worked great! I let him know that most would only need the kernel itself, and not the whole rom/kernel bundle.

To make sure that the kernel alone would work, I extracted the boot.img and put it in one of his older kernel releases. Played with multirom and all my roms very well. Host mode charging worked correctly in them all. YAY!!!!!! Im sure it will not be long before release.
[Nexus 7 Original Development] rydog66:
My primary rom my internal rom just got a major update & I need to do a full wipe/reset to install it. I am nervous with the multi-rom, as it's new territory for me, installing essentially a new internal primary rom. Does anyone have suggestions or advice for me to do this correctly??

Thanks,

edit: it looks as though I can just install it using multirom as an internal rom (like I have been doing) then after its installed, go to settings and change it and make it boot by default. Then will I be able to delete the old?? Is this how I want to go about doing this?? Please advise.

Thanks again!
[Nexus 7 Original Development] BelzIgoh:
Just do the full wipe/reset using twrp. then flash your new rom. after flash is done, dont forget to Inject curr. boot sector. :good:
[Nexus 7 Original Development] PVL_93_RU:
Just do full wipe from within recovery like on normal TWRP
[Nexus 7 Original Development] rydog66:
ok, will I lose my nandroids? should I back them up to my computer? Inject curr. boot sector will bring back the multirom menu on boot right.

no, u will not lose your nandroids as long as u not do Format Data at TWRP.

yes, it will bring back the multirom boot menu.

[Nexus 7 Original Development] rebel1699:
Hey guys. Timur opened his kexec support rom for download last night! Keep in mind, it is beta, but I have been testing it and everything works awesome. Especially his custom menu in settings called "USB Hosts". I have been running my otg devices all night, and not had my battery drop a single percent. Also the ability to enable fast charge while using otg! All these things require a y cable. Dont have one? He has schematics to build your own. Or, you can buy one on e-bay. I built two for myself.

When installing this rom, DO NOT SHARE KERNEL!!!!!!!! The baked in kernel is kexec enabled and built to be in perfect unison with the rom. A standalone kernel may be upcoming to cover all roms, but with a few tweeks. No promises, just the impression that I get. That is 100% for Timur to decide.

Here is the download link

http://rootzwiki.com/index.php?/top...ost-Power-Management---USB-Audio#entry1137968

Guys, please give Timur a huge thanks, as he was not obligated to do this in any way.
[Nexus 7 Original Development] rydog66:
Thanks for the great news! I do appreciate Timur taking his know how and expertise and setting aside the time that it took for him to build this amazing rom/kernel for our community. Thank you as well for all of your efforts in facilitating this project. I cannot wait to give it a go myself. Thanks again!! an you please give the link to thank Timur again please. The more times it's posted the better the chances of people actually thanking him for his hard work.

I am updating my internal MAIN goto rom, like discussed the past couple few posts. The rom is SmoothRom 5.1 with major changes so full wipe is a must. I have used jamesst20 the dev that makes the SmoothRom's flashing/wiping tool in the past with fantastic results, as it is evtremely thourough.

http://xdaforums.com/showthread.php?t=1902016

My question is how will this work with multirom? I didn't have MR installed when using it previously. Like mentioned earlier in this post, this is replacing my current internal main default rom, so I NEED it to be solid & done right. That's why I chose the SmoothRom, I LOVE how my N7 runs when using it! Please give me some feedback based on first hand knowledge & experience. I'm no expert but I'm not an idiot by any means either. I just need for this to be done right. I want to take my time and really LEARN this uber important step so I can learn good habits using the MR. Thanks so much for your time and assistance. They both are very much appreciated.

Hey people,

I tried searching for an answer but got lost in the deluge of search returns. How does MultiRom allocated storage space for each different ROM?

Example: I want to install Ubuntu (not Touch) alongside my current Stock Android, does MultiRom partition off the internal SD?
[Nexus 7 Original Development] ikslawlok:
There is no partition. It is stocked in a hide folder.

[Nexus 7 Original Development] farmerbb:
Any ROMs you install for MultiROM are stored in /sdcard. There's no PC-style partitioning done. MultiROM uses some tricks with permissions and remounting to give the illusion that each ROM is its own separate thing.
[Nexus 7 Original Development] kyelo2:
apt-get dist-upgrade

I didn't see the earlier warnings (posts #1449-56, #1517) about using dist-upgrade with ubuntu, and so I did an apt-get dist-upgrade. The result was a boot-loop, and after that neither ubuntu nor the stock android would boot (both had been doing fine before).

I managed to get into recovery, and (I think) injected the boot sector, and now can boot as before into Ubuntu on a USB stick. But still the internal (stock android) ROM will not boot.

I am using multirom version 8 and TWRP v2.4.2.0.

Does anyone know why this happens? Is there any way to get my Android back without a re-install of the factory image?

Long post incoming.

My guess is that it wouldn't be hard, but I can't know until I try - I have no way of knowing how different the devices are.

No, not yet.

Kernel added to second post.

No, Nexus 7 has ext4 on it's "internal sdcard", so there's really no reason to do any partitioning, not mentioning the fact that it is not even possible. When installed to NTFS/FAT32 USB drive, it uses ext4 images, if the USB drive has extX filesystem, it just creates folder, just like on internal sd.

The reason why my kernel does not work is it does not flash whole boot.img but just the kernel - you need to reflash it somehow, because Ubuntu rewrote the whole of it. Use boot.img from some backup or flash some other kernel which writes whole boot.img (e.g. franco's).

You just need to re-flash boot.img and remove folder /sdcard/multirom while in recovery. I should create some uninstall ZIP or recovery option. Hm.
[Nexus 7 Original Development] s33d1ing:
I know it says not to flash a ROM via flash zip when you select one of the ROMs you have installed with multirom but if I am just updating the ROM to a newer version, is that okay?

There is two ways :

- update internal ROM

- update secondary ROM

After flashing a kernel you have to "inject curr boot sector" in multirom menu.

If inject curr boot sector doesn't fit it, try refreshing multirom. You shouldn't have to do that often but occasionally I have had to reflash it.

Not sure if this is the right place to post, please let me know if not!

I'm having trouble with my 'internal' ROM. It started ages ago when I was playing around with something I probably shouldn't have (can't remember what). At the time I got some kind of error upon booting but since my secondary ROM worked fine, I didn't bother sorting it out.

Now, whenever I try to boot from the internal it will get stuck in the boot animation (no matter what ROM I flash). It's not a huge issue as the secondary ROM still works without a problem, I'm just wondering if anyone knows how to fix this so internal becomes bootable without losing any data from the secondary rom?

Thanks for any help!

EDIT: I saw there's an option in TWRP's wipe menu to delete rom. Will that just remove the internal.rom, leaving the working secondary? And what will that do to my existing data?
[Nexus 7 Original Development] rebel1699:
Ubuntu desktop for N7 13.10 (Saucy Salamander) was made available on the 2nd. The normal ui is not usable yet, but it is looking promising. From what ai can tell, touch operation is greatly improved. Again, this is not yet usable, as unity ui and video drivers need worked on.

Yes. From what I have gathered, Tasssadar got TWRP to have full rotation control. He sent the fix to the TWRP devs and may be in the next release. However, there is a download available now. I will get the link. I dont think it is modified for multirom yet.

Well can you help me out? Cause once I installed v2 I have never been able to boot ubuntu with the gui.

What steps did you use? Or are there some files outside multiboot that I should delete or some kernel that would prevent the thing from working properly?
[Nexus 7 Original Development] rebel1699:
I'll do what I can. I flashed v2 earlier today, but deleted ubuntu shortly after because i wanted a fresh start while getting adb and fastboot operational (which I did, yay!). Anyways, I used no special operations to get it going. Install, reboot, choose ubuntu, and it built and started after 10 minutes. I did however flash francos boot image and then inject it into current boot. My internal rom is rasbeanjelly 4.2. If you have any specific questions, i would be more than happy to help in any way.

[Nexus 7 Original Development] Rafase282:
I have EOS as the internal. I tried with bricked kernel and trinity for the internal. Other roms work fine. Perhaps I should format the /data/media (sdcard) and start over. When Ubuntu was working I had it install most of my usual apps. Audio was not working tho. I created a new user and gave it admin rights and remobed the ubuntu one. If I remember well that might have given some issues but shortly after I started over with v2 and I have been unable ever since. I'll try Franco's kernel then.
[Nexus 7 Original Development] rebel1699:
Once it gets going, you can fix audio. Upon boot, unmute and turn up volume. Then, suspend from power menu. Exit suspend and sound will be functioning.

Wow, you really are spammersfast-writers :)

Well, you still did not send me screenshot of what does ubuntu says. I can't do anything without at least that, would be event better if you could get me /proc/last_kmsg (I've already described "how" twice in this thread).

I am currently pushing kexec patches, which are requied for booting from USB, to Ubuntu and Cyanogedmod. But I still don't have flash drive big nor fast enough to boot from :/

As from GS3 - no. I will not do this for device which I don't have. Reason is simple - I would not be able to test it properly. You can't write 6k lines of code and just hope it works.

Memory leak? Do you know which process causes it? Use "top" command to find out. I guess it could be the famous "media" process, which scans "sdcard" for media files. And, well, when you have ubuntu and several android roms in there, it is lot of files. Should stop after ~30 minutes though.

Is this internal rom? I don't get this bug in Internal ROM, only when booting one of the additonal ones. Maybe it is because my internal ROM is 4.2.

This is the internal rom yes.. Stock rooted 4.2 .Running Nova Launcher with Dock bar turned off. NO other tweaks or changes. Yes its reporting right .. i checked it against fx file explorer and others.

I am not complaining at all as it does not effect anything running.I even killed all the Google services . Its just strange Did not do it until after the multi rom. Who really knows why its happening just wanted to point it out.No real issues are caused from it..

Erica Renee

Thanks for all you effort .
[Nexus 7 Original Development] rebel1699:
This could all be caused because even though ubuntu is stored in the android fs, it is still seen as a root partition (of sorts) of a foriegn nature, with permissions and rules that android might clash with a bit. Just a thought. All in all, I am loving the os diversity on my N7.
