Its happened to be before you have to either flash other rom or another kernel or could also restore from nandroid

That happens when you flash the wrong Kernel also. Make sure its for supersonic. Most of the kernel devs have kernels for multiple phones on the download sites.

[Q] Kernel Question for Froyo

I have the new Froyo on my Droid Incredilble and was thinking about trying a different Kernel to try and improve battery life. My question has 2 parts
1. What would be best kernel for this?
2. Do you lose any data when replacing the kernel? Will I have to put all my stuff back on phone after replacing kernel and is the replacement simply done via clockwork in recovery mode?
Thanks for all your help and suggestions
The kernel is all personal preference. Flashing a kernel does not require you to wipe anything nor does it remove anything. A nandroid backup is highly recommended though.

I am also trying to find a download of the stock kernel for froyo so that I can revert back if I want but have not found one yet.

[Q] kernel flashes leave screen unresponsive

I've tried flashing several kernels, only for the purpose of overclocking, but everytime, once i reboot the phone, the screen will not respond to any touch! I have to open the keyboard to unlock the screen, then navigate using the trackpad to restore my original rom
I was stock, n i've flashed both Baconbits 0.1 n 0.3, then flashed the Virtuous Sense rom, which worked normal. But i wanted the newer kernel (jan 11? I believe) but the same result, so i reverted to the jan 4 original kernel
Can anyone explain to me why any kernel i try flashing leaves me stranded? Can i fix this?

YouTube doesn't play and setcpu

Ok so I'm new to the whole flash kernal thing. I just flashed a kernal today and after the process was over I realized that my setcpu on boot would just restart continously and wouldn't allow me to access my phone at all. So after wiping the data and reset to factory I didn't install the setcpu but then my YouTube app would load videos but when it plays it only shows a white screen. I wanna know if there is a particular kernal that can fix these issues or perhaps the Rom I'm using is bad but its the fresh Rom and I haven't had any of these issues with this Rom until I flashed the kernal can someone please help me.

Have you tried a different kernal or reflashed the rom?
We're comin from a pure power source.
Yep, its the kernal. Different Evo's behave differently to kernals. That is a tell-tale sign the kernal you are trying isnt working with your phone.
Yes I have flashed a different kernal and still same issue I haven't reflashed the Rom. But I know there has to be a another kernal that fixes this issue so my only concern is what kernal is it

Where can I go to try out different kernals
Sent from my PC36100 using XDA Premium App
The dev section has kernals, or kernal manager from the market. Or the rom you flash has the kernal already

[Q] change kernels

Hi there.
I've been using gtg's "UNnamed"ROM. I absolutely love it. However, there are some bugs that lead Me to believe the kernel is at fault.don't ask me why I think that, i'm a noob. Lol. Anyway, I tried to flash Chris 41g's acs recovery repack (matching el13). When I try booting after that, it shows the galaxy s 2 start screen and then goes to a blank screen.
I'm wiping cache and dalvic before I flash, using cwm to flash the zip from my phone. Am I doing something wrong? Or is there some reason why one wouldn't be able to do that?
I don't want to bog down the dev thread with this one.

Can you open up a rom zip and insert your own kernel?

I have something annoying im trying to figure out. Every time I re-partition my phone with ODIN I end up having to freshly install an MTD ROM. When I install an MTD rom for the first time, my phone reboots without allowing me to flash the kernel i desire before the ROM boots up. Some people flash kernels without fresh installs, but I cant stand doing that. I end up having to re-install the same ROM in the new recovery so my phone doesnt reboot before I flash the kernel. I hope this makes sense.
Anyone know what directory the kernel is in for the rom zip file? Can i swap it out with my desired kernel without flashing problems?
You can. But you should really just use the kernel that the rom comes with. It is what is tested by the dev and devs get annoyed by bug reports from people using other kernels.

No I think you'd need to recompile the whole ROM and incorporate the zImage aka the kernel it flashes also have the updater script prompt that....its complex and I don't even know how to do it...

I do normally, but in this instance, im using StarksyROM. The original ROM comes with Shadow 0.3 I believe.... there is a charging issue unless the kernel is updated to 0.4 or above.
(the bug is the battery charging display doesnt show up when the phone is off)
