The stock kernel is 'kernel.sin', and it's present inside the ICS FTF file.

Thanks. If i flash custom kernel (.img) with fastboot mode and when i want to come back stock kernel, i flash stock kernel by flashmode, is it right.
(Sorry for my bad english)

[Q][GSM] Stock Kernell 4.0.3?

Hi guys, i used the search button but I don't find anything. I am looking for the Stock Kernell 4.0.3 for the gsm version of the galaxy nexus. I want to try it on different custom rom instead of the custom kernell provided, but i can't find anywhere where to download it... Any link or suggestions are appreciated...
Search with one l as kernel doesn't have 2
Sorry... Kernel whit only 1 L....
anyone whit this kernel?
I would also appreciate this.
Here you go. This kernel is built from AOSP 4.0.3 r1 using full_maguro-user configuration. Completely stock and is insecure (so you can root yourself).
I'm using my own ROM with this as well. You can flash with fastboot:
Code:
fastboot flash boot boot.img

I haven't tested it as I'm not using CWM, but it should work.

Need the stock kernel for 4.1.2 or 4.1.1 please

Hey, I tried (almost) all custom kernels but battery seems to be best at stock kernel.
So I would like to have the stock kernel but I don't know where to get the zip from
I'm running 4.1.1 Can I flash the kernel that shipped with 4.1.2 (assuming it's different and better)?
If not then a link to the kernel with 4.1.1 would be much appreciated.
4.1.1 Stock kernel

Thanks, I guess I'll wait for the zip to be posted somewhere. (Drivers of that ADB thingy can't be installed on Windows 8 or something like that.. Can't use fastboot)

[Q] Installing Tyrinty Rom for Acro S while Being on XZXperience ics rom

Hello ..
I have Acro s Unlocked bootloader and i am using XZXperience rom
now i want to flash Trinity Vengeance RaptorXL V2.9 UX12.5B
do i just flash to rom files inside recovery mode ?
or i have to flash the stock jb rom first and reroot it again ?
Thank you
just wipe data and flash through recovery any rom is flashed this way if it's a zip file
Best way is to flash it with Flashtool. Flashing a ROM through CWM will never be as accurate.

Where to download stock boot.img and META-INF for Arc S?

I started making my ROM with Android Kitchen and I dumped system folder from ftf file.
But I cannot find META-INF and boot.img to use for ROM.
I tried using MIUI v4 META-INF and boot.img but I get status 6 error while installing ROM. By Kitchen's FAQ it means something is up with update-script. So, I need to find stock boot.img for latest ICS Arc S firmware and associated META-INF with update-script.
I searched for those files for more than 8 hours, still can't find them.
I hope if anyone posts them that I could be able to normally install ROM without a problem.
Thank you in forward.
Err, there is no stock boot.img. All stock kernels are provided in the stock firmware packages also known as FTF files.
Depending on what you need it for, you can download the source code(, make the modifications) and compile it yourself.
Hmmm, how am I going to make custom ROM without boot.img if it is needed(or is it?).
I can't get any other custom kernel because I want to make ROM for locked bootloader phone.
Do you know what should I do to complete ROM if i can't have stock boot.img?

Yeah, that's what I though after someguyfromhell wrote a post and I made a new zip without boot.img and deleted write_raw_image line from update-script.
Right now I am searching for solution to other problem(some folders and files are not showing up on my sdcard while viewing it in Windows, so I have no space to drop ROM in there, will try when I fix this).
Thank you both for replies, will try to fix this soon.

If you are going to do a ROM for locked bootloaders, then there is no boot.img needed at all. Locked bootloader means stock kernel, means no boot.img.
Also, it is not needed. Some ROM developers supply their own kernels together with the ROM, however it is not a requirement.

Flashing Stock Kernel

Hi,
I am currently running the 5.1 version of the Digital High GPE rom and would like to flash the stock kernel. I looked some on htcdev but all I found was the kernel source. Is there any place that I can find a flashable zip that will install the stock kernel? Thanks!

You can find a firmware zip there with the stock boot img included.

Awesome! So I extracted the boot.img from the zip file. Now, just to confirm, all I have to do is use the command "fastboot flash boot boot.img" and I should be set with the stock kernel? Thanks!

That would be correct.
Don't forget to flash the matching stock modules too !

Which is why extracting the boot.img from the GPE ROM as I stated in the thread that I linked to is the better option.

So if I flash the boot.img from the stock rom like you stated, do I also have to flash the modules?
