I tried the factory image even though its checksums didn't match cause everything looked fine, but it doesn't work properly. I tried multiple times and it'd the launcher would lag, freeze, get the remove option stuck when trying to remove widgets, and gave me tons of errors. I know I'm far from the only one experiencing this, so Google obviously screwed up. Have you seen any of this, or have you not tested it yet?

Edit: Yup, same problems. I don't wanna trust it, so I'll keep waiting.
[Nexus 7 Original Development] Tasssadar:
Doesn't depend on me, the kernel sources were not yet released.

No, nothing like that. I flashed it twice, once as new secondary ROM and once to update my secondary stock 4.3. Launcher works almost the same way as it was on 4.3.

Hey that's cool! Thank you for all of your work, Tasssadar.

But the problem is I have not been able to get the wi-fi to work in UT. The system "sees" my wi-fi, reports that it is WPA protected, but when I click on "connect" I am never presented a dialogue box to enter my password. Do I need to be doing something else to get the wi-fi to work?

Is everyone else getting the wi-fi to work?

Maybe I'm just dumb. But here's my setup. Aokp as main ROM. 4.3 stock ROM as secondary. 4.4 rom in this thread as third option. Aokp and 4.3 boot fine. Sharing kernal. 4.4 I can't get to boot. Not sharing or sharing kernel. Just stays at boot animation. I'm on bootloader 4.13. Thought maybe that was in issue, that's why I asked a few posts back. Any thoughts? I've yet to get a 4.4 ROM to boot.
[Nexus 7 Original Development] bonzer2u:
flash the oxydo v13 kernel to the 4.4 rom and give it a try. Im runnin 4.4 as a secondary fine but already on bootloader 4.23 so that still could be your issue

Any chance of original 4.4 kernel with kexec? (because i cant boot my secondary rom)? or can i install oxydo or faux kernel on 4.4 kitkat primary rom?
[Nexus 7 Original Development] bonzer2u:
you can flash any kernel to any secondary by selecting the rom in multirom and 'installing' the desired kernel, you just need kexec modified kernels applied to all primary/secondaries for everyone to run, currently oxydo v13 is the only kexec enabled kernel that runs on 4.4, but that will change once the 4.4 kernel source is released from google.

[MENTION=3418703]Tasssadar[/MENTION] have you ever thought of making a guide to porting MultiRom?

I am stuck on figuring out a few things. My kernel supports kexec-hardboot from mkasick

I am not understanding that the only thing I need to modify is the kernel including my device.

Could you explain what to include in mr_init_devices.c and how do I build multirom not just recovery code?

Also what is this MR_KEXEC_MEM_MIN := 0x85000000? How do I find the specific to my device other than that we have twrp working latest code and all other basic support.

4.4

Im running 4.4 with oxydo 13 as a secondary on a ext 4 usb drive. It looks ok but It's not rooted!!! How can I fix this?
[Nexus 7 Original Development] rebel1699:
Yes, if the kernel you are running has host mode charging support AND you have a "y" cable. However, ubuntu desktop does not support it at kernel level, so only android can do this. For what its worth, tasssadars modified TWRP even contains the patch, so you can charge while installing to usb.
[Nexus 7 Original Development] bonzer2u:
Just ran a few tests with the faux mainline 22, oxydo v13 runs much better when bumping the cpu to 1500 using the latest trickster. Im sure these will be much closer after their formal 4.4 releases.
[Nexus 7 Original Development] physwizz:
It looks like I'll have to get a y-cable.

you don't have that option with faux however you can set the cpu/gpu clocks with oxydo using trickster mod
[Nexus 7 Original Development] browy:
Hi Tasssadar. Just a quick question. What happens when I go to recovery and delete a ROM? Will that ROM be completely removed with all of its data, or do I have to do a full wipe first before deleting it. I'm just curious 'cause something strange happened to me. I once installed SmoothRom as one of my secondary ROMs and removed it after some days using. Yesterday I flashed SmoothRom again and the homescreen background isn't the standard background that should come with it but the one that I set weeks ago before I deleted it. It's no big deal, I just want to know is there something left that I don't know of when I delete a Rom without wiping. Thank you for your time.

Hi, today Google released update from KRT16O to KRT16S, and i downloaded it from HERE. But when i try to flash it via Advanced -> MultiROM -> List ROMs -> Flash ZIP it Fails :(

Can you help?
[Nexus 7 Original Development] Tasssadar:
OTAs will never work on a system which is modified in some way, because they contain only bytes which were changed between two Android versions. If files on the device are changed (custom ROM, different kernel, MultiROM-injected init, sometimes even root), OTA simply can't be applied. Everyone who roots his device should be aware of that.

Wait for the flashable ZIPs, I'll make them once I'll get home.

[Nexus 7 Original Development] Tasssadar:
No. Use the ZIP I made to upgrade, it can be flashed over existing 4.4 ROM - you'll have to flash SuperSU again, but your /data will stay intact. It is big, I'll give you that, but there is no way I'm making binary patches like google does.

Correct me if I'm wrong.. If I have 4.3 stock with kexec kernel as internal and install any 4.4 rom (secondary) without sharing kernel or installing 4.4 kexec kernel rom will not boot. 4.3 roms work well but I guess that's because I have 4.3 as internal, right?

y-cable

I decided to make my own by splicing a usb cable (red and black wires only) into my OTG cable.

It looks like it charges the N7 when it's off but not when it is on. I also think it may be supplying power to the external drive while it is running.

I tried a number of different ROMs and kernels but I haven't yet found one that will charge the tablet while accessing the external drive.

Any advice?
[Nexus 7 Original Development] rebel1699:
Give me a few minutes, and I will find the link to a good diagram by timur. I have made many for the tablets around here. As far as a kernel with host mode charging capabilities, metallices m-kernel a63 works great. Others do as well, but metallices is my favorite.

Addition: Use this link. Scroll down and there are diagrams. Best of luck.
[Nexus 7 Original Development] physwizz:
I use m-kernel a63 on my secondary (smoothrom). Do I need to flash it on to the primary to get the y-cable to work?

[Nexus 7 Original Development] rebel1699:
I am an idiot. I didnt even put the link in my previous post.

http://mehrvarz.github.io/usb-host-mode-power-management-nexus7/

Just as long as the kernel that is currently running on the system you are booted into has host mode charging, it should work.
[Nexus 7 Original Development] physwizz:
y-cable

Thanks for the link. I did something very similar. I cut my OTG cable in half and joined the leads back together while splicing in the red and black leads from a usb male end of a cable.

It charges my phone and also charges the nexus 7 when using bodhi linux, but it won't charge when I'm using any of my android roms.

Edit... I finally got it to work with cm 10.1 and Timur's kernel:)
[Nexus 7 Original Development] TheIronMaiden:

[Nexus 7 Original Development] ylixir:
I've been maintaining a guide as I have time. Arch has some issues though. Mostly it needs a new kernel. Speaking of which...

Tassadar, I wonder if you could tell us where you got the kernel for your Arch image? Did you recycle an android kernel or use vanilla linux? In either case if you built it yourself could you provide a brief rundown of the process? I'd like to try to get it at least updated to 3.4 and maybe even over the holidays try to get it working with a more vanilla kernel (if it is indeed using Android sources) by splitting Nexus patches from the Android patches and seeing where I can go (assuming I have any free time over Christmas break heh).
[Nexus 7 Original Development] Tasssadar:
It is kernel straight from Ubuntu Desktop. They took android kernel, added few things and enabled several config options. It should be doable with that 3.4 kernel, see http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-nexus7.git;a=summary for the exact changes.

[Nexus 7 Original Development] flash5000:
You can create a secondary ROM from a TWRP backup if that's what you want. Otherwise you could use TitaniumBackup or a similar app.

But why do you need to start from scratch when updating a secondary ROM? Are you aware that you can flash ZIPs for a ROM using 'list ROMs'? That's also valid for updates, you just cannot setup another new ROM this way...

Gesendet von meinem Nexus 7 3G mit Tapatalk
[Nexus 7 Original Development] blucmal:
OK so no way to restore a nandroid backup to secondary rom I have to use a backup app. What does it say don't flash Roms from this menu? If I go list ROM/flash zip.
[Nexus 7 Original Development] thereal_bigjake:
Just flash the new rom zip with the flash zip option to update a secondary rom. Ignore the warning for this.
[Nexus 7 Original Development] flash5000:
No, I think you misunderstood - you can restore a nandroid backup to a secondary ROM: Add ROM -> Backup (instead of 'ZIP file').

Key is to add a 'new' ROM, I don't think you can restore a nandroid to an existing ROM - but it doesn't matter anyway.

I don't know why Tasssadar put this warning there. I made lots of ROM updates this way and never had any trouble.

[Nexus 7 Original Development] blucmal:
Just to be clear I wanted to create a backup of secondary rom delete that rom ad the new version of that rom install gapps then restore data to the new version of the rom I just deleted, rather than have to go through and re download all the apps and setup the layout etc. I relised I could restore a backup as a secondary rom but thats not what Im trying to do.. Thought it was weird that I could do a backup but then could not choose where to restore the data from that backup to. All I was trying to do was just restore the data from a backup to a secondary rom. Not restore a backup as a secondary rom. Hope you understand what I mean.
[Nexus 7 Original Development] thereal_bigjake:
Well you could do that in the main rom slot then take a backup of that and flash it as a secondary
[Nexus 7 Original Development] Xentar712:
That did it! Thanks!

Do you recommend making the "internal" rom the one most commonly used or does it matter? I know I like PA better but it's in beta and still no 3G, so it won't be my primary until it is compatible(Hence why stock is still my primary). Once it's compatible, are there any benefits to replacing my primary rom?
[Nexus 7 Original Development] xopher.hunter:
Is there currently any way to make a backup and restore it as an added rom? Or possibly backup an added rom?
[Nexus 7 Original Development] Tasssadar:
It doesn't really matter - all roms are in the same memory, so the speed is not affected in any way. The idea is that the "Internal" ROM is the one which is most used. It is also the one which will probably boot if something goes wrong with MultiROM.

No. Adding to my todo list.
[Nexus 7 Original Development] Rafase282:
I havent tried it but ti backup a rom other than the internal you could just copy its directory somewhere safe and then move it back if needed. After flashing v2 whatever previous rom that was on the sdcard will be displayed on the boot menu. For the internal a backup from recovery should do.
[Nexus 7 Original Development] jamesst20:

[Nexus 7 Original Development] jamesst20:
Sadly, it doesn't work on my side :S

Did I miss something?

Here is what I did:

1. Went into fastboot and flashed the recovery

2. Installed MultiROM zip from recovery

3. installed a rom

4. rebooted

5. Now I can see the ROM list : Internal and the ROM I installed

If I select internal, it boots fine, otherwise it says 'an error occured. Stopping multirom to avoid error etc..' it says also that it makes a log, but it doesn't :S

What is wrong?

Edit : I also notice that /sdcard/multirom/roms/ROMName/system is empty

Thanks!
[Nexus 7 Original Development] Rafase282:
If it's system is empty it means it was meant to be the last one that booted but somethign went wrong and you went into the internal one. When a rom is not in use, you should be able to see it's system files. I suggest you remove it and install it again. I had that problem before and opted to clear everything. the roms, factory reset and delete data to ensure a clean install. That might not be necessary but it is an option to keep in mind.

Remember that if you want to flash gapps on a rom that is not the internal you need to go to rom list, click it and then select flash zip otherwise you will mess up the thing.
