Nope sorry, you can't flash kernel seperatly with s-on and unlocked bootloader. If you make s-off you can.

The kernel must be compatible with the ROM. Usually, Sense version and Android version need to match.

I'm sorry, is it actually possible to flash a kernel with unlocked bootloader and s-on? Before I s-offed, I could not flash New kernel via recovery, is there a way to do it other than via recovery?
Edit: I suppose if the new kernel was in boot.IMG format, then you could flash it in fastboot.

yes The Kernel In the .zip format can be flashed in two steps.
First Flash The Zip File In Recovery
Then Flash Boot.img via Fastboot,fastboot flash boot boot.img

What's the first step for?
I think the whole point of this thread was the op wants to try different kernel with existing Rom on the phone using a kernel.zip .
My original answer was if your s-on you can't flash a new kernel.
What I didn't however include is you can't do it via recovery, using a downloaded kernel.zip which was my mistake. But I would have thought that was obvious, because that was the original question.

But...what does flashing the zip do that flashing the image doesn't? Am I missing something?

According to me,The Flash Zip is required to place the files in the system directories...
It would be the same reason you have to flash the boot.IMG manually after flashing a Rom from recovery (cwm, 4ext etc) because it doesn't get flashed to the boot, same reason kernel doesn't flash via recovery. HTC unlock but still s-on doesn't allow you to mess with kernel directly or via recovery except using fastboot.
Atleast that's my understanding.
May I also add my own personal experience, I went straight to htcdev to unlock my phone, my experience with my HTC legend gave me the knowledge to do it without issue except the boot.img which through me a little. Long story short after flashing Rom and boot.img I wanted to try new kernel but it wouldn't work then I used google and found out via a different forum site the reason, which is HTC'S official unlock does not allow access to kernel with s-on....

Hi XDA. Sry for my bad English
yesterday i had rooted my HTC Wildfire and then i installed SetCPU. But when i started the program, I could only underclock my phone and not overclock it. Does any1 know why?
Plz help me
Are you using a overclockable kernel with whatever rom you're using?
Sent from my HTC Wildfire using XDA App
Welcome to the forum.
Questions and anwsers go in the Q&A sub-forum.
Now for your question: you need to install a custom kernel, that will allow overclocking.
#2 i think i'm using a standard rom
# 3 Do you have a guide to do that?
Download an overclockable kernel
Boot into recovery 2.5 (Flash the attached file for a temporary 2.5 recovery)
Flash kenel.
#4 do you want me to copy the files into my Wildfire and the go into recovery?
Yes, but the attached files isn't the kernel, you still need that if you want to flash it.

Yes, copy the kernel of your choice and the update1 zip to your SD card. Then flash update1, then the kernel.

It just depends on the script in the flashable zip I believe. If its an old zip cwm needs to be downgraded.

I have tried several times to flash the new baseband radio. With 4EXT and I have tried rename file and fastreboot. Non works.
With 4ext I get massage I'm not allowed to flash etc ..
Am I missing something?
This will be the first radio I flash..I'm still on stock.

You can flash a new radio file .zip via CWR. It's very simple
I need to install clockwork recovery to be able to flash radio? I thought 4ext touch could do the job as well

Any recovery can.
Depending on your hboot, you may not be able to flash radio via recovery.
Flashing via fastboot is always better though.
I tried changing the zip file name and put it in sd card then boot phone into fastrecovery by holding back button and boot. But it doesn't recognize the file.... So I don't get any choice.

That's your problem. You can't flash radio via recovery with that hboot. You have to do it via fastboot.

Ok.... Did some searching.. Found out i had to extract the zip then flash the img file. Am i able to flash back and forth between radio versions. Also.. Do i need to reinstall the rom after the flash?

No need to reflash roms after radio change. A general rule to follow is that you don't mess with your radio if you don't have problems with your phone. One wrong move during flashing and it can brick your phone.

If it ain't broke, don't fix it. Unless like me, you have balls of steel and are still amazed that after what you've put your phone through over the years it still functions. Hell, it even survived me accidentally dropping it.... err.. against the err... wall...
Sorry for the long ? I did read some where if you have Soff you don't need to flash boot.IMG every time when flashing a ROM can i just flash the zip with cwm

Yes, if S-Off you can flash directly from the device itself, using CWM etc.
Are you sure you have an S-Off HOX? If so Lucky you !!
People have been searching for S-Off on HOX for a long time now, with no result !
Unlocking with htcdev doesn't give you s-off so you will still need to flash the boot.img with fastboot

I'm currently on stock 3.14 and got a update notification for 3.20, the only mod if done is a custom kernel. Is it safe for me to install the update, I've also got clockworkmod recovery

You need to have stock rom(boot.img) + stock recovery to install updates...

Can I just reflash them both?

Yes... You can.. But make sure your using the correct boot and recovery files to flash...
Edit: since ur on stock rom... U just need the correct recovery file... Thats it..
Sent from my HTC One X using xda app-developers app
Not if he flashed a custom kernel too (as stated in the OP) Then he needs the stock boot.img and also the stock modules !
What's the main version number
Fastboot getvar version-main
I can make you a flashable zip for the modules. That we way you can safe yourself from restoring a full backup
Is it possible to flash kernals,boot.img without a PC?
Sent from my HTC One X using xda app-developers app
No, only with s-off devices. So custom kernels will be flashed from the recovery, custom roms probably won't flash the boot.img because most devs took out the script

Yes custom kernels like XM for instance should be fully installable via recovery. But If the phone has no signal or WiFi after install you must flash the boot.img manually
