This may be a stupid question, but it's one I've never seen a definative answer for. When installing a new ROM and Kernel, which should be installed first, or does it not matter, and should you reboot recovery between installations, or just install one over the other?
If the ROM includes the kernel I personally install the ROM w/ kernel then reboot. After it reboots I then go back and install the alternate kernel. Might not be necessary but has always worked for me. Hope this helps.
I also just flash the rom then flash the kernel. No rebooting. I've never had a problem.
You will be fine to do rom then kernel no need for reboot

I'm using the stock Gingerbread "Leak" rom version 4.12.651.1 that was leaked recently and I played around with it at first. Took several pictures and videos and enjoyed getting back to having Sense on my phone.
I used Kernel Manager Lite to download and install the Netarchy Toastmod-cfs-havs-more-sbc kernel and at now everytime I open up the camera it shows a white screen and I can't take a picture or video anymore.
Is there a why to uninstall or undo this kernel without having to reflash my Evo? I'd like to go back to just the stock kernel i guess. I even tried to use the Kernal Manager Lite to download and install a different Netarchy Toastmod kernel but it wouldn't install it over a previous kernel and when I clicked on the kernel I already have installed it won't give me an option to uninstall it...
Thanks for any help you guys can give me.
Find the stock kernel for that ROM and flash in recovery after wiping cache and dalvik cache.I will try to find stock kernel for that ROM.
Yeah there's no way to undo once u flash a kernel.....may I make a suggestions for ya foe the future.....Ive been doing this for a while......flash the ROM and make a backup once yur all setup...this way u can tinker with the rom and kernels and themes and what not.......and if those tweaks don't work for ya......u got a backup of a fully stock rom......

Thanks guys for the awesome advice!
Reverepats, it's funny you said that because that's the first thing that I thought about after this happened and I'm still kicking myself for not backing it up before flashing the kernel LOL It'll be a lesson learned I guess
Ianmb, that would be AWESOME if someone had this. I'll keep looking for this too but if I have to I guess my only recourse would be to wipe it all and reflash all over again... /sigh
There is a post for a working kernel for that ROM on the second page if the ROM is the stock 4.xxx. Stock kernel 15 I think, can't upload file from my phone?
ianmb, thanks for looking but I can't find any stock kernel #15 out there. not even google can help me =/
So it's possible to reflash a kernel over an already installed kernel? If i find the stock kernel how do I go about installing it? Via recovery?
Forgive me if I'm wrong...but if you just reflashed the rom without wiping, I believe it would install the stock kernel that came with the rom

Yes you can flash a new kernel over an installed kernel...just wipe cache and dalvik prior to flashing

At what point do I install a new Kernel?
I'm about to flash a new ROM and it is recommended to use a particular Kernel. At which point do I do this? Just before the first boot? After the first boot?
Thanks!
Kernel comes with the ROM you are flashing. So my suggestion is to try the one that came along with the ROM. If for some reason you are not satisfied with it may it be high battery drain, undervolting, overclocking, or missing governor options, that's when you look for another kernel.
There are 2 types of kernel for Desire, Sense based or AOSP based. You can't use one with the ROM based with the other.
You install new kernels the same way you flash a ROM. Kernel comes in a flashable zip. ONLY wipe dalvik and cache before flashing a new kernel. No need to wipe system at this point. Yeah flash it after the first boot, although flashing it right after the rom wouldn't hurt I believe.
Just flash it right after you flashed the ROM.

Hey all can't post in the rom's thread so here will have to do hope someone can answer this.
Got the rom working fine. The issue is A.) I lose CMW
why? and is there a guide for installing cmw standalone without flashing a kernel?
B.) gapps don't appear even though i def flashed them as OP said to.
Permutations tried so far:
- OP verbatim
- OP + F10AOKP kernal as recommended in OP
Thanks to any and all
using cwm with an ics kernel has been causing bricks. It happened to me once already had the have best buy replace my phone. Most devs aren't packing cwm with ics kernels for the time being this may change but for now its safer this way. When I need to flash something I use mobile Odin to flash back to el26 then I wipe cache flash what I need then flash an aosp kernel : ) and boot

Thanks for clearing that up for me! Also I figured out my gapps issue some trial and error led me to follow CM9's gapps link and that did the trick.
you lose your recovery because of two related reasons:
1) on this device (not sure if it applies to all samsung devices, though i think it does apply to most), kernel and recovery are packaged together and therefore always flashed at the same time. when you flash a kernel, you always lose whatever recovery you had before.
1.1) since you flashed aokp, which includes a kernel, you therefore lost your recovery because of reason 1. no big. next time you need to flash something over AOKP or make a nandroid, just odin el26 kernel which includes cwm (search for it, not gonna link it), and do your thing. just remember to reflash the ROM before rebooting cuz el26 is a gb kernel which wont work with aokp (because it's ICS).
Also you should read the first couple post in the thread....it explains what is what with the ROM and that it doesn't have cwm ...etc

Hi guys! Since I am a noob I haven't flashed a custom ROM before I wanna ask you do I need to change my kernel in order to put the amazing Hashcode's JB ROM. I already have a root privileges and TWRP installed. What are the steps then... There is hardly any info about the installation process in the ROM's topic. And how to install google apps - through the TWRP or? Thanks in advance. Waiting for your answers...
ROMS always have the kernel included. Everything is installed from recovery. Just wipe partitions, flash ROM, flash gapps, reboot.
Thanks man, I really appreciate. Will try!
What saved said....the kernel is included In all ROMS.
When life gives you tech....Make use of it.
So, I was relocking my HOX in order to get the OTA JB update from carrier (H3G) in order to use the new Viper ROM.
All went well and managed this. Got re rotted and installed CWM ans Super SU.
However, I read that before installing the JB Viper ROM it was important to do a full wipe. Using CWM i did this. Specifically I did the wipe data/factory reset, wipe cache partition, wipe dalvik cache and format system.
Now my phone is stuck on the white HTC screen. Please help.
Thanks
You formatted system, which basically wiped the rom. Reflash and don't format system.

And don't forget to flash the boot.img file !
Thanks for the quick response and apologies for the basic and wrongly termed questions. Just panicking a little.
How do i get the ROM and boot.img on to the fone? Because it sticks at the white screen the pc doesn't seem to detect it.
Last time i used a stock RUU and followed that process. Will i be able to flash the new Viper ROM instead?
thanks
The boot.img is supposed to be flashed from the PC. To get the Rom into the phone you need to go back to clockworkmod, go into mounts and storage and press the mount usb thing
Edit - to flash the boot.img find a thread about fastboot. Don't worry you'll get there
To get the ROM on the phone boot into cwm and GOTO mounts & storage
Then mount USB storage
It should now be detected as a drive on your PC and you can copy the ROM back over

Thanks. I did as you guys suggested and was able to install the Viper ROM (used the tweaked stock kernel as recommended in the download).
So have a ROM now but I have no service with my carrier and when I try to connect to wifi it says 'error'. Have I missed or done something wrong?
Cheers

While installing the rom, did you choose at the kernel question to keep the stock kernel and modules

Got it resolved. I had used the tweaked kernel and assumed that this was not standard, so when asked about which kernel i was using i said it wasn't the viper one.
So i went back to basics and used the kernel that came with the ROM zip and just flashed both. Working fine now. The only question is whether I could have used the tweaked kernel and answered yes to using the viper version?
Thanks for your help. Felt like I have learned a fair bit in the last 12 hours though!
Well if you flashed a different custom kernel you can answer that with the question so it won't load the stock modules but backs up the custom modules from the custom kernel. This way it won't mess up functionality.
When you use a boot.img without it proper modules it can mess up those things you experienced. Hope i make my self clear
