I hope you can. I cannot get adb to work in TWRP, no matter what I try.
[Nexus 7 Original Development] -Johannes-:
I also can't get a recovery.log...

But I just made a short video of the freezing.

https://www.youtube.com/watch?v=OXkiI135M4Q&feature=youtube_gdata_player

sent from nexus 7
[Nexus 7 Original Development] rebel1699:
Yeah, I finally just flashed back to TWRP from 7-09 and everything is working fine. Re-flashed 7-20 and all the problems came back. since I cannot use adb to get the log pulled for diagnosis, Im just going to stick with 7-09.

I have downloaded 7-20 TWRP three times, fastboot erased recovery twice, flashed one time via flash image gui, and once with fastboot via laptop. Like I said, 7-09 works fine every time, and 7-20 borks every time.

also, even when I enable adb in recovery for multirom (advanced-multirom-settings) adb still does not detect the tablet when in the multirom boot menu. ADB is only working when the Internal rom is running. Never had this many troubles.

Your video is shows exactly what mine does. The screen flash is exactly what it does, and gets stuck there. Upon reboot (by holding power) trying to boot to that rom will result in looping back to TWRP.
[Nexus 7 Original Development] Rafase282:
Here are the outputs.
[Nexus 7 Original Development] rebel1699:
Yours differs from mine only in your media_rw is showing 28, and mine shows 25. Other than that, all the same.
[Nexus 7 Original Development] Rafase282:
How would I go about fixing it? I have no clue what is causing it,
[Nexus 7 Original Development] Tasssadar:
I still fail to see anything wrong. Can you take a photo of what does ubuntu says when booting? Also, send me the boot.img which is in /sdcard/multirom/roms/Ubuntu, I'll check if it is okay.
[Nexus 7 Original Development] rebel1699:
Not a clue. I also noticed your boot.img is much smaller than mine, but that is just probably due to things I have added. I'm watching Tassadars evaluation to learn a little, just like you. Lol :D

Life keeps me VERY busy, so xda and google are the only time for education I have time for.

Regarding the picture, it clears itself before proponting for username and password at tty1 so I cant really get back to the error.

Here is the boot.img
[Nexus 7 Original Development] Tasssadar:
boot.img looks fine to me. Try to look into files at /var/log and to /home/ubuntu/.xsession-errors, see if there is not some error there. Other than that, I really do not know. How much free space did you have when installing Ubuntu?

PS: I've got a donation, which means I can buy big & fast flash drive. That means booting from USB will be done. If I make it 'till christmas, that is. I have to start working on other projects around that time, but I think I will make it in time. Big thanks for that donation :)
[Nexus 7 Original Development] Rafase282:
Just for the heck of it... I decided to remove the boot.im from the Ubuntu folder and replace it with the one from boot.img-Ubuntu on the top directory, it boots and I have gui. I noticed the file sizes were different. So for some reason it did not copy it right? I don't know what changes are done to the boot.img to begin with.
[Nexus 7 Original Development] Tasssadar:
boot.img is changed during ubuntu installation, question is why yours did not change properly. I'll try to download & install ubuntu again on my Nexus 7 tomorrow (it is already 2AM here, and I have school in the morning...), maybe something has changed in the Ubuntu rootfs.img image.
[Nexus 7 Original Development] Rafase282:
Cool.

On a side note, has anyone being able to mount a usb using otg cable? Mine failed to mount. I'm going to experiment with Ubuntu now instead of doing my homework. =b

You will have to explain better to me about visudo. I would like to check that option out.

How about apps is it shared between roms?
[Nexus 7 Original Development] rebel1699:
Apps are not shared. But, they both occupy the same partition (/sdcard), just as the op states.
[Nexus 7 Original Development] Rafase282:
I noticed that my nexus7 boots straight to ubuntu.

Also the visudo thing didnt work.

I just did sudo nautilis, went to / then changed permissions on the last one where it says other, I gave read-write and view access so my user should be able to view the files eithout problems.

---------- Post added at 03:23 AM ---------- Previous post was at 03:19 AM ----------

Okay, this is not the best way to do it security wise, but at your own risk (any user will have full acces to your roo fs)

1-) in terminal type sudo nautilus, then input password

2-) Navigate to /

3-) Do a right click and in properties select permissions

4-) On the "others" tab select folder access "create and delete files"

5-) on the file access select "read and write"

6-) Click apply changes, let it finish and you are done.
[Nexus 7 Original Development] Tasssadar:
It's adb pull /tmp/recovery.log - not /temp/.

That's weird, I don't know why it does not work. There does not seem to be anything wrong in that log. Well, try to put both ZIP files to the flash drive and install from there. You can try unmounting /data from "mount" menu in recovery before you start, too.

Windows drivers are crap, you need different ones for recovery adb than you do for adb in Android ROM. I don't know which ones, never used adb on Windows.
[Nexus 7 Original Development] stadicon:
I'm having the same issue on Nexus 7 32GB 3G.

That would be impossible since, if you unmount data, you can't enter the Advanced->multirom menu.

@Tasssadar

Hi

I read change-log of Multi-ROM v12 and TWRP v2.6

But i couldn't find change-log of " Kernel w/ kexec-hardboot patch (CM 10.1): kernel_kexec_cm101-4.zip "

also checked ur wiki but ...

could you please write about it and if wrote send link

-

I m already on kexek Kernel CM10.1-3

Does upgrading to kexek CM10.1-4 wipe everything ?! (or should i do it manually!?)

Or best choice; it s like normal updating and not need wipe :D

!?!?!?

Thanks

:good:
[Nexus 7 Original Development] rebel1699:
Glad you mentioned windows drivers sucked. I remembered the arm compiled adb i had, so I used my phone to grab the log.

[Nexus 7 Original Development] Tasssadar:
Okay, here's new recovery, the crash happend when installing new secondary ROM which shares kernel with Internal. It was just a typo, fixed.

TWRP_multirom_n7_20130721.img

It was just updated to match CyanogenMod's changes. In this update, it was just one commit, which seems to be fixing some kind of security vulnerability.

Hm, I really can't reproduce this. Does it happen with recovery from 9.7.2013?
[Nexus 7 Original Development] rebel1699:
Tasssadar, thank you man! I knew it had to be something simple. Awesome!

No longer gonna use adb in windows. The arm adb and fastboot binaries have proven themselves indispensable.

Nice job on the new versions Tassadar. Thanks for all your wonderful work on this stuff.

If you unmount data then go to advanced > Multirom, it says Multirom is not installed.

I also completely wiped my Nexus and did a fresh install of stock 4.2.2:

Then I flashed TWRP_multirom_n7_20130720.img

Then I installed Slim-tilapia-4.2.2.build.7-OFFICIAL.zip

Then I installed multirom_v12_n7-signed.zip

Then I tried to launch Ubuntu from my OTG drive which it was already install on, but it said I was missing the kernel patch, as I forgot to flash the kexec patch. I flashed kernel_kexec_422.zip and now I'm in exactly the same position as I was before...Doesn't boot Ubuntu, just a black screen and back to Multirom menu.

Also cleared out and formatted my OTG usb drive and did a new install of Ubuntu, same issue.

So it might be an incompatibility with Slimrom and Multirom or with Slimrom and kernel_kexec_422.zip.
[Nexus 7 Original Development] roligov:
Ok there is more to this issue. I've ruled out Slimbean as the issue.

I wiped EVERYTHING! Then:

Installed stock image-nakasig-jdq39.zip

Installed stock bootloader-tilapia-4.18.img

Installed TWRP_multirom_n7_20130721.img

I didn't restore any apps or even login to my google account. Just booted, enabled debug mode and copied the files across. Then:

Installed multirom_v12_n7-signed.zip

Installed kernel_kexec_422.zip

Installed Ubuntu and it wont boot it on either USB or Internal. I don't know what to try next :( Anyone else have tilapia and having the same issue on 4.2.2? Is kernel_kexec_422.zip the correct kernel for Ubuntu?
[Nexus 7 Original Development] Nbsss:
Was about to post to say the same thing lol.

I'm willing to chip in, maybe someone can organise a bounty thread when we have a new forum for the Nexus 7 gen 2.

I think Tasssadar deserves it, for all the work he's done for the n7 community...
[Nexus 7 Original Development] Tasssadar:
The kernel should to match your Internal ROM, but it does not matter - if you choose wrong kernel, you just would not be able to boot your Internal ROM.

Which Ubuntu images are you using?

Also, it might be better to contact me on IRC - it's faster. I'm on freenode, channels #twrp or #ubuntu-touch as tassadar_ (webchat).

By the way, is there anyone with 3G Nexus 7 who has Ubuntu Touch working properly?
[Nexus 7 Original Development] roligov:
I've managed to make some progress. I downloaded an older version of Ubuntu and got it booting when installed on the Internal with the same configuration as before. saucy-preinstalled-touch-armel+grouper.zip and saucy-preinstalled-touch-armhf.zip are the 2 files that are working.

Also on my Verbatim Store and Go 8GB, if it's formatted to NTFS even the older version of Ubuntu won't boot, I had to format it as fat32 for it to boot from USB (exfat is not recognized). So right now the only thing I've changed is the version of Ubuntu. I'll do some more testing tonight and report back. I'll catch you on IRC, I agree it will be much faster :)

Thanks!

Hello, I'm on MultiROM v11.

I try to upgrade my "Internal ROM" with cm-10.1-20130722-NIGHTLY-grouper.zip.

Here is the cm-10.1-20130722 changelog.

All seems to be good during installation.

But, when i tap on "Boot", it won't boot.

No boot ;-(

So i'm back on cm-10.1-20130721
[Nexus 7 Original Development] Tasssadar:
Are you sure that error.txt is correct? It is from v10, and it is trying to load different kernel with kexec, which should never happen with Internal ROM Oo

What exactly happens after you press boot? It just stays on "Booting ROM..." window forever?

By the way, Ubuntu Edge: http://www.indiegogo.com/projects/ubuntu-edge
[Nexus 7 Original Development] ikslawlok:
That's it !

After you press boot, It just stays on "Booting ROM..." window forever.

Maybe error.text is an old one.

Which log file could I post to show you the problem ?

Maybe it is a CyanogenMod problem (?)

I will see with the next release.

Thank you for your previous answer

Then let you device boot normally, enable USB debugging. Copy the 4 files: multirom_v12_n7-signed.zip, kernel_kexec_422.zip, saucy-preinstalled-touch-armel+grouper.zip and saucy-preinstalled-touch-armhf.zip to your internal storage and reboot to recovery.

Install multirom from TWRP.

Install kernel_kexec_422.zip from TWRP.

Then hit advanced and select Multirom > Add rom and then do the ubuntu install. Install to internal first to confirm it's working, then try OTG drive if you want.

There is no need to completely re-flash the device. Ubuntu Touch has daily builds and is under active development, so it's possible the image is broken at the moment. Just wait a few days and try again.

Okay, 4.3 is out. I made flashable ZIP again - clean 4.3, no root, no anything, it's just the factory image in flashable ZIP: http://goo.im/devs/Tassadar/android_430.zip or http://d-h.st/8fE

It does not work with MultiROM yet though. There have been some changes, and it may require some update to MultiROM and recovery. Kernel in 4.3 was also changed, so I'll have to make new patched kernel - the 4.2.2 kernel does not work with 4.3. The source code was not yet released and I can't do much without it (it will probably take a few days, like it did for 4.2.2). Also, it seems like 4.3 is using SELinux.

EDIT: Sources are out, let's see what I can do with it.
[Nexus 7 Original Development] ikslawlok:

[Nexus 7 Original Development] Tasssadar:
Recovery was updated to 4.3 changes and 4.3 kernel with kexec-hardboot patch is available.

To install 4.3 as secondary ROM, simply use the flashable ZIP to "Add ROM" and then "Flash ZIP" the patched 4.3 kernel to that ROM.

To update existing 4.2 ROM, flash the ZIP over it and then flash the patched kernel.

Warning! Existing root does not work with 4.3! Because of SELinux added in 4.3, Superuser apps have to be updated, in the meantime, you can use ChainFire's experimental 4.3 root: https://plus.google.com/u/0/+Chainfire/posts/WqS2E9kkN1L

New bootloader is also part of factory 4.3 images (it's version 4.23). It doesn't seem to break anything like last bootloader update did, so you should be safe to flash it if you wish to do so.

[Nexus 7 Original Development] Tasssadar:
Okay, I like how the new N7 looks. I'm pretty nervous about just asking for money, but I'm willing to go with this if you are.

I'm thinking of doing kickstarter, something like this: http://www.indiegogo.com/projects/modaco-switch-for-the-galaxy-s4-i9505/x/4034303

The problem is, I'm in Czech Republic. We can't buy N7s here. Dees_Troy (of TWRP) is however willing to buy it and send it to me, provided I pay the N7 and shipping in advance and that he can port TWRP to it first. Unfortunatelly, shipping to Czech Republic costs _a lot_, plus customs and tax.

So, the kickstarter would be to $229 + $48 + $84 + $19 = $375* $500 (indiegogo does not support lower targets) and it's target would be not only to get me a n7 to make MultiROM, but also to get TWRP on that device. It would, of course, use fixed funding - if it does not get the target $500, you'll get refund and I'll get nothing.

If the kickstarter is extra successful, I might buy some more devices (hello, n4) and port MultiROM on them, too.

Kickstarter can only be used if you're in US or UK, so I have to use Indiegogo, which has some limitations. Lowest possible amount is $500, and you can only fund by paypal.

What do you think?

* Prices:

$229 - Nexus 7, 16GB

$48 - Customs and Tax, approximately

$84 - Shipping, calculated on US mail website

$19 - Some margin "to be sure"

[Nexus 7 Original Development] Tasssadar:
I know, lunacy, right?

Nobody goes to XDA for money. Yes, people send me some donations, which I'm very grateful for, but you won't get nearly as much as if you, I don't know, got half-time job at McDonalds. I'm doing this - spending many hours programming and testing and researching - because it is fun and interesting for me, because I like to play with these portable devices.

I'm only doing this because I can see some people want it, and because it would be great to make MultiROM for multiple devices. I'm asking you to get me that device so that I can continue making this thing better, not to pay for my work. If it fails, well, then too bad.
[Nexus 7 Original Development] :
LOL. Another well known dev on xda did the same thing. Guess what, he got a different device and doesn't even work on the s2 anymore. ;)

Not calling you a liar or saying your intentions are shady. Just saying that expecting donations to buy a device for you is kinda crazy. That person I speak of didn't reach the goal he needed, so never got an s2. But he magically got a better phone just afterwards. ;)

Like I said tho....goodluck.

Oh, and people donating to a dev who's work they appreciate is fine....I've done it multiple times.....but being asked for it is another story. IMHO. :)

[MENTION=3418703]Tasssadar[/MENTION] - With all that said, let us (myself, and those interested in continued development) know when you get your "campaign" started. After 183 pages of development I'm confident there is more to come. So far, MultiROM is one of the neater things to come to Android in my opinion. Heck, I could blow $20 at the bar one night. Just as well put it to better use for once.

Thanks
[Nexus 7 Original Development] Tasssadar:
I'm currently preparing the indiegogo page, if it goes well, I'll start it tomorrow. There's pretty much nothing to lose, so why shouldn't I try it. BTW, I'll use the "fixed funding" model, so if it fails, you'll get refunded.

kj2112's point of view is very valid and I have thought about it - for you, there's the danger that I might not deliver. I can't really do anything to negate that, but every kickstarter project is like that, yet a lot of them are successful, so I figured I'd try it.

I'm still very interested in your opinions, so please, continue.

EDIT: I wonder - how long should the campaing be? I'd think 30 days is appropriate, but I really don't know Oo.

EDIT2: Any ideas what perks should I do? I don't really have anything extra to offer, everything already _is_ in MultiROM :/
