Re: [WiFi&3G] MultiROM v7 - updated recovery (Feb 02)

I'm actually running 4.2.2 on secondary. Working well and all :thumbup:

What I did was - backed up internal ROM(smoothRom) to my PC, just in case flashing 4.2.2 wiped internal data.

Then flashed stock 4.2.1 because was missing system apps and all, then flashed the 4.2.2 update in recovery.

Installed multirom and modded twrp again real quick

Backed up 4.2.2

Restored SmoothRom to internal , then added 4.2.2 to secondary via Backup in mutlirom.

Seems like there would be an easier way :rolleyes: but this worked

I did all this to see what the 4.2.2 fuss was about. It does feel smoother than 4.2.1

.. But it could just be in my head :D

Hi,

The kexec patch still works on the new kernel 4.2.2. So the opportunity to continue MultiROM. Yes!!!!!
[Nexus 7 Original Development] J_Caselles:
I guess 4.2.2 doesn't really mean new kernel...

I have 4.2.1 as my primary ROM. What should I do to flash 4.2.2? Flash stock recovery back, update via standard OTA, and flash again MULTIROM?

thanks!

Re: [WiFi&3G] MultiROM v7 - updated recovery (Feb 02)

You shouldn't have to flash stock recovery if your internal 4.2.1 is pure stock with system apps in tact and all. You can just flash update normally via twrp.

Here's an easy guide https://www.youtube.com/watch?v=rfZ4f5Bdgfc&feature=youtube_gdata_player

Sorry sorry sorry Now I figured all out, it's explained in the first post, and now I know, the zip file is stored in /cache. All I needed. :victory:

[Nexus 7 Original Development] N@th_OC:
I think you're wrong 4.2.2 fixes bluetooth and audio problem, and those stuffs are mostly located in the kernel.

So yeah it will work, but on what purpose?

I remember someone (UBER if i'm not wrong) saying flashing Franco on top of 4.2.2 is like flashing back to 4.1.1.

And i'm pretty agree with him...

4.2.2 has new kernel, but the sources were not released yet. Not much I can do about that, but it looks like it works okay even with older kernel.

Yes, it's possible, just install multirom in Stock.

So get tablet running stock.

Install Multirom.

or do you mean install it as additional ROM? With Let's say PA being "Internal"?

Hey, so i tried this today on my nexus 7 running bootloader 4.13 as suggested, with cm10.1 nightly 20130213 and motley kexec patched kernel, i did all as suggested in op, installed multirom through recovery (cwm), rebooted to bootloader fastboot flashed the patched twrp recovery, rebooted and got the promt to select rom, picked internal/cm10.1 and it worked, went to recovery did add rom and added the ubuntu 13.04 image with its original name " raring-preinstalled-desktop-armhf+nexus7.img.gz ", which it took some time to install (guess around 10-15 minutes) but without errors, rebooted after it was done, got to pick the ubuntu installation and it started booting, i could see the "ubuntu" logo with the dots under it moving, after some time (perhaps 1-2mins) the logo and purple screen disapperead and there was a blank screen "for ever" (i left it at least 30 minutes), held power button so the tablet rebooted and retried, but to no avail, again rebooted to recovery went to manage the rom and change name from "raring-preinstalled-desktop" to "ubuntu" rebooted, but no avail, meanwhile if i picked the "internal/cm10.1" option

now i removed the rom and installing it again and ill rename it to "ubuntu" before booting first time.

one more thing, there was no console or anything, that is mentioned in the op and i used internal storage for it not an usb drive, perhaps ill try an usb drive next if it wont work

Does anyone have input what i could have done wrong? Thanks

Edit, ok a second time around, same thing, the purple screen with ubuntu logo keeps loading than at some point it get dimmer and at the end blank screen (backlight is on)

edit 2: i can make a video of how it "boots" if anyone wants to see it, i assume there wouldnt be any debugging possible over usb?

edit 3, im installing it on an usb drive now, will see if i can get anything from there, perhaps i can get its syslog after failed boot, through a pc, by mounting the usb.

edit 4: so i installed it on an usb drive, again it started booting fine, the process was a bit different, more stuff written in console, but at the end blank screen again. ill attach a video once i upload it.

R: [WiFi&3G] MultiROM v7 - updated recovery (Feb 02)

Hi!

I've try to flash android with the new version but now the system information shows me that android isn't update to 4.2.2 but still 4.2.1...

And when I searching for new update, the system says to me that no updates are available!

I've install multirom and the recovery!
[Nexus 7 Original Development] Tasssadar:
4.2.2 kernel sources were released, so here's 4.2.2 kernel with kexec-hardboot patch: http://www.mediafire.com/?x38j3jur23afpt9

By the way, only 3 new commits in this kernel, and none of them related to audio as far as I can tell, but one of them _could_ fix crashes with video playback.

Bootloader was also updated in this OTA. New version is 4.18 and it broke kexec-hardboot for MultiROM. I managed to fix it though, so here goes MultiROM v8.

I would really like to know what have they changed in this new bootloader Oo

That "USB drive not detected if plugged-in too soon" bug should also be fixed in this version. If you still experience it, check that it says "..trampoline v2" in bottom left corner in "Misc" tab in MultiROM and then report it to me.

Bonus round: I made flashable ZIP with 4.2.2 stock ROM so you can multiboot it. It is normal ROM ZIP like any other here on XDA, so install it via Advanced -> MultiROM -> Add ROM. No root, no anything, this is pure 4.2.2 from Google: http://goo.im/devs/Tassadar/android_422.zip

"MultiROM" title in main UI is now centred, if you haven't noticed)

PS: regarding updating your internal ROM - update it as usual, as if you didn't have MultiROM installed. If you lose MultiROM in the process, then use Advanced->MultiROM->Inject curr. boot sector option in recovery.

[Nexus 7 Original Development] creepy33:
1) Download the 4.2.2 Google image :

2) Download Google Nexus 7 TOOLKIT

http://xdaforums.com/showthread.php?t=1809195

3) Unpack the Google Image (the zip into the tgz file too), Install the Toolkit

4) Put .img files in the appropriate directory of the Toolkit (directory named "put_img_files_to_flash_here")

5) Flash images except userdata.img & recovery.img with the menu 11.

6) Root again your tablet with the menu 4.

7) Boot to the recovery and install the zip files (kernel_kexec_422.zip and multirom_v8_n7-signed.zip) on your internal Rom

8) Enjoy

[Nexus 7 Original Development] Tasssadar:
The daily image seems to be broken. It happens. Wait for new one or try one of the older ones. I can't affect it, but it is to be expected that they will be broken sometimes - it is not stable release.

Read the third post in this thread. In short, the main problem is that I don't _have_ the device.

Yes, you can. You will probably also have to either reflash MultiROM zip or use Advanced->MultiROM->Inject curr. boot sector option. You shouldn't loose any of the secondary ROMs (some might not work with 4.2.2 boot image though).
[Nexus 7 Original Development] jawonder:
Tried flashing the stock 4.2.2 rom and i got an error, tried to restore a backup and got an error also . I had to fastboot a regular TWRP recovery to restore by backup, so it has something to do with the modified recovery. Any ideas "Tassadar" ?.

Hmm.. I am confused, I just went to reboot from within the recovery and then chose recovery... So it just rebooted straight into recovery, I also just wiped before a flash when this happened...

Anyway if it happens again I will grab a log, but it wasn't a big deal to me at time so I didn't think about a log...

I just tried to load the latest image dated 2/16/2013, 562MB loaded fine no errors.

After reboot I got the purple ubuntu splash screen with animated orange dots then afterwards the black screen of death (no error message). I have let it bake 15 minutes with no response.

Just my opinion but Im thinkin that there may have been a fundemental change with ubuntu that multirom doesnt like???????

What you'll want to do is, after updating with apt-get, reboot into recovery, go into the Advanced -> MultiROM -> List ROMs menu, select the Ubuntu install and choose "re-patch init"
[Nexus 7 Original Development] Starfire-1:
I must have missed something along the way...

I have a stock 4.2.2 Nexus 7 and added Multiboot successfully (multiboot zip from recovery, TWRP from fastboot and then patched 4.2.2 kernel from TWRP)

I downloaded the 2/14 and 2/15 images of Ubuntu and installed the ROM via TWRP (I have tried both internal and external USB). Upon first boot, I see some of the typical Linux boot messages, WiFi etc. It loads the autobrightness driver and dims, then loads a little more then goes black. I have read that it takes a little while for the first boot, so I let it sit for 20-30 mins before I gave up. The last boot message before it goes black is about the kernel crash daemon - which might not mean that it crashed however.

Exactly what should I be looking for on the first boot when it takes time load? BTW, I have never seen a graphical screen (e.g. the Ubuntu logo and dots)....

Thanks!
[Nexus 7 Original Development] bonzer2u:

Its already expanded so it loads alot quicker but the background graphics will be scrambled until it finishes loading then normal. Note that you will get about 300 updates with sudo apt-get update which should render the error I posted above.
[Nexus 7 Original Development] Tasssadar:
1. The image is broken right now.

It happens, this is still not stable realease after all. And it will be broken for a while - it's weekend. Use the image bonzer2u posted.

2. Ubuntu not booting after update

intramfs-tools, the only package I have to change in order to multi-boot was updated and the patched files were rewritten. As you figured out, you have to use option "Advanced->MultiROM->List ROMs->*ubuntu rom*->Re-patch init" in recovery.

Yeah you can even use the "broken" image and repatch it immediately after installing in multirom recovery and it works (I tried it on an usb drive).

I have a different issue though: even if I set never to lock/require password on sleep, I always get the login screen after turning screen on and off, but thanks the keyboard doesn't show up, so I can't write pass... Anyone had this issue or has an idea how to fix it? Apart from that it's terribly laggy and buggy, even the gentoo on my pandaboard, that is only half as powerful runs better...
