[Q] Timur and Kexec-Hardboot kernels together!? (using MultiROM AND USBRom together?) - Nexus 7 Q&A, Help & Troubleshooting

Hey everyone.
i was wondering if i could have Timur's great kernel for USB Host power management AND be able to boot in ubuntu or other android roms, using amazing MultiRom?
i found that i have to use a patch or sth. like that, but i have no idea what i should do.
can anyone give me a step by step guide? noob proof?!!

Timur's kernel already includes the kexec-hardboot patch. When installing Ubuntu with MultiRom you are to select "Don't share kernel with Internal ROM".

Yes, Timur added the patch several months ago. And when you install ubuntu, you dont need to pick dont share kernel. The way multirom is set up, you cant share the kernel, because when you choose ubuntu as the medium, the option is automatically removed.

I should have been more clear. The 2013-01-24 kernel does not have tje kexec patch. He implemented it after that date. Use the cm kernel from april or may.

Is it ok to use cm kernel on stock rom? :S
Sent from my Nexus 7 using XDA Premium HD app

Cm means cyanogenMod, right? So installing the cm kernel on stock rom may harm my device, and the stock kernel doesnt support kexec, right?

So, my problem gets worse. Can anyone give me a link to stock kernel?

Ubuntu touch nightly build installation.

Using the Ubuntu touch nightly builds, should I only be flashing the armel-manta zip and phablet-armhf zip?
I see there are additional files for system, boot, and recovery img, and was wonder if I should be using any of those as well.
Also, I am using a Nexus 10, hence looking at manta builds.
Thank you.

For the nexus 10, you can use the phablet-flash tool (on Ubuntu) that makes this easy. If you're doing it manually, I think all you need are the 2 .zip files. The instructions for manually installing can be found here: https://wiki.ubuntu.com/Touch/Install#Manual_Installation

I don't own this device but it looks like you're flashing this like any other Android rom. If everything breaks you can still flash with Odin to stock and install CWM again.

If all else fails you can revert to stock Android and then move to a custom ROM from there.
Or more simply... boot into recovery and flash new ROM zip. No need to go back to stock
maybe its brick

This is just a developer preview so remember that many things don't work, i think you should wait for 17 October when official release for nexus devises comes out, after that devs will start making ports of the OS to other devises.

[Q] TouchControl app on stock kernel of 4.3

I can't post in the official development thread, so I've posted here:
Does anyone know if TouchControl (aka slide2wake) app works on the stock kernel of 4.3 version?
If it doesn't, any solution to make it works?
Thanks
No.
You will need a custom kernel which has the feature to work.
Sent from my Nexus 4 using Tapatalk 2
Thanks.
Can you suggest me a stable kernel with this feature in it?
No one has really made a custom 4.3 kernel except for Franco but that only has a few changes. You'll have to wait for the Dev to actually update the app and he'll release a modified stock kernel like before

What he said. The pure stock kernel has injecting disabled or whatever it was so the dev of Touch Control would need to compile stock kernel and remove that security feature.

Actually, I think the developer of touchwake has to update this mod to be compatible with 4.3. So just wait out for a while.

The developer also needs a kernel based on 4.3 for it to work as well. Not just the app, as the app relies on the kernel and the kernel relies on the injection from the app.
Thanks to all, I'll wait for a modified stock kernel by the developer app.
They discovered a way to modify the stock 4.3 kernel on a Galaxy Nexus to make Touch Control work!
So it's just a question of days until we get a modified kernel for the Nexus 4.
Hopefully...

Can't flash Kernel

I'm running CM 10.2 Nightly 9/27/2013
I'm trying to flash Franco Kernel Plus R184 but everytime I flash it, it goes through but ends up reverting back to the CM kernel. I tried flashing stock Franco and it still does the same.
I'm still looking for help on this matter
Gotta download the alternate kernel he provides.

Kernel question

Hello guys,
Iam new to the Nexus 4 forums. I have experience with other phones with flashing etc. I have a couple of questions:
I flash a kernel(zip) after I flash a ROM. That seems to me the right way. The flashing seems going right but after restarting the phone somewhat stutters, its no lag or something like that.
Iam running PA with now the regular kernel but when I flash Franco or Neo kernel it happens.
Anybody a idea what i am doing wrong?

For PA use jwr kernels. Not jss. Neo and Franco both have two versions. Jss and jwr.

There's also this zip which allows Jss kernels to be used in jwr roms.

[Q] CM 10.2 nightly won't boot after flashing franco r191-JSS

Hello,
I am running CM 10.2 (latest nightly). I flashed the franco kernel r191 for the first time and it bricked the phone. The boot animation won't come up. It gets stuck after the Google logo. I would appreciate if you could help me out. Fortunately, I had a full nandroid backup and was able to recover my phone.
I use the TWRP recovery.
Thanks.
You need to learn what the definition of bricked means.
a bricked phone is worthless and unrecoverable, it makes a great paperweight/door stop. flashing a kernel that wont boot is not bricking a phone, and not close, and there are many ways to recover from a non booting kernel, nandroid restore being one way. you can also just flash a good kernel or your rom to recover.
Thank you for clarifying the definition of brick. I did not know that. Please feel free to chime in regarding my original question. Thank you.

What IS your question? From what I've read, you were able to restore your nandroid, right? Just don't flash that kernel if it messes things up.

try a different franco kernel. are you sure that you pucjed the right kernel? 4.2.2 kernels dont boot on 4.3, and 4.3 kernels dont boot on 4.2.2.

According to the author, I am supposed to flash the one that has a JSS tag in the file name. http://franciscofranco.minooch.com/Nexus4/4.3/zips/
I am sure I downloaded the correct file and flashed the right version. Since I am new here, I am not allowed to post in the original thread, which is here:

no. custom kernels no longer work on cm properly, if at all.thats probably is the reason why franco kernel wont boot. cm changed their base code from aosp to qualcomm a few weeks ago, and that broke the ability to use custom kernels on cm. custom kernels are based on aosp, and qualcomms code breaks stuff because of it.
Thank you so much! Now I understand why.

Started a couple of days ago. Not sure if the r191 is the cause or the cm 10.2 nightly.

As said previously CM is the cause, Franco still remains AOSP based, you can try hellscore kernel, Google it, it as a nice reputation for amazing battery life and has a CM version of it.

I don't even like the way that term is used to be honest. To me a soft brick is more or less something that requires a JTAG.
A bootloop or a failed boot just isn't any type of brick at all really as far as I'm concerned.
You really should change the title of the thread. Franco does great work and really does not need to be slandered. After all cm is preventing your device from booting not Franco's kernel. If you want to rant maybe you could change the title to cm bricked my phone
