[Sprint] Flashing Kernels

[slyd]

I've heard it's better to flash a kernel over the ROM with the stock kernel. So after you first flash a rom, nandroid with the stock kernel. Then after flashing a new kernel, you should restore the original nandroid with the stock kernel before you flash another kernel rather than just flashing kernel on top of kernel. Any truth to this?

 

[MizzouBrent]

Sort of. There is a kernel cleaner script you can flash to eliminate this problem

I just read a little bit about kernel cleaning scripts. Looks like it could be dangerous for the uninformed. Seems like one script is not necessarily good for all kernels,

The cleaner script has worked fine for me w/ every kernel flash. It cleans init.d, cleans app data left behind from kernel apps, cleans some kernel files. However, you can always reflash the ROM you're running (only wiping cache/dalvik) and then flash the kernel of your choice, if you choose not to use the cleaner script.

What would be dangerous about it?

I did a Google search for kernel cleaning scripts and found this. Looked dangerous to me. http://www.crashcourse.ca/wiki/index.php/Kernel_cleanup_scripts

 

[MizzouBrent]

Hmmm well no issues for me yet!

 

[slyd]

Which one do you use?

[MizzouBrent]

That's the one.

 

[NaterTots]

So just flash that before a new kernel?
Wipe Cache or dalvik?


Thanks

 

[MizzouBrent]

Yeah I wipe both and then flash the cleaner script.

Hi...newbie here...w/ SPRINT GNEX

When I flash a ROM, Am I also flashing the kernel? Does the ROM file includes a kernel? Or do I need to flash them separately? I have been studying partitions structure and where things are in the file system. I am concern of updating my device and rendering the device unable to receive OTA updates from sprint.

Thanks in advanced for feedback...

Welcome to AF!!! Every ROM has a kernel included (usually stock). If you'd like to flash a custom kernel, you'd flash it separately.

Not being able to receive OTA updates is no big deal, we usually get to run the updates sooner than they are released officially by being rooted! The way we (The Root Community) keep our devices current, is by flashing ROM's with those updates included.

Yeah any ROM is going to be either equal to or superior to an ota update.

I would say all are superior unless you are flashing a stock unrooted ROM

Great. I can live with taking ownership of updating my ROMs...if I understand correctly, once I go down this path, I should stay on it and avoid OTAs, whether they work are safe or not. Correct? If so, let the fun begin. Thanks for the feedback and guidance!!

 

[MizzouBrent]

That's correct
