Since I was an android virgin until just before Christmas, I'm still trying to get to grips with all the cool stuff that can be done.
I've rooted the phone and unlocked the bootloader. Everything else is currently stock.
I don't want to go to Clockwork recovery, or Cyanogen/MoDaCo ROMs. Not yet. I'm still savouring the "Google Experience".
However, I have three questions (which may turn into many more ) about flashing new kernels, and I don't want to clog up any specific kernal thread with noob questions.
1) Does flashing a kernel wipe the whole phone the way unlocking the bootloader did?
2) If you're running stock ROM with new kernel, will you still pick up OTA updates as before?
3) How do you get the original kernal back if you don't like the new one (or if it just goes totally tits up)?
Thanks guys
EDIT: Yes, I realise there is a search and this may well have been asked before. But before someone points this out, I'd like to mention that if you do a search for "android kernel", you get approximately 1 bajillion hits...

1) No, you should not wipe anything before flashing a kernel. You should however do a NANDroid backup.
2) You should be able to but it will wipe your kernel.
3) Restore your backup from #1

flashing a kernel doesnt wipe your phone, it simply replaces whatever kernel is in your phone at the moment.

2) Is fine, as once I've figured out how to NANDroid backup, re-flashing it should be easy enough. 3) Is fine, once I've taken the backup in the first place.

Excellent, thanks!
Ok. So all the NANDroid guides I've seen here start with ADB and Fastboot (which I remember doing when I rooted the phone), but then they say about flashing alternative recovery images... is that necessary? Or is that what the fastboot thing was?
I've just checked and ADB still works, so if fastboot is an alternative recovery image, am I good to take a NANDroid backup, and if so, how do I do that?
If Fastboot is not an appropriate recovery image, do I need Clockwork Recovery (is that different to the "CWM" I see mentioned around here?)?
The Nexus S guide I read said that there was a NANDroid option in the Clockwork Recovery. Now this isn't in my recovery options, obviously, but I assume with ADB, a command prompt and a few instructions, I can do it manually. Maybe.
Bear with me guys, I'll get there eventually...
Ok, scratch the NANDroid questions. NANDroid is a backup tool contained in the Clockwork Mod recovery image.
Using Fastboot, you can boot from the recovery image without flashing it (using this guide here), so I've still got whatever recovery image I got when I did Paul's rooting technique, but have booted into CWM once to do the NANDroid backup.
I may flash CWM later, that's a task for another day.
So. Now I've got the backup (and thus, booting from that image again later, the ability to restore from it), I can try flashing the kernel. Which I can do from the regular recovery image.

To flash from the stock recovery you must rename files update.zip just FYI. I've said it before and I'll say it again; there are no possible negative repercussions from flashing a non-stock recovery image.
Apparently it was unsigned, so the stock recovery wouldn't do anything with it.
Back in CWM and it worked fine. I may have to flash that, it's damned useful...
So now I have a new kernel!
Thanks for all your help

It is very useful indeed! Enjoy your kernel
Ah, am I right in thinking that if I flash CWM, I can't revert back to stock if I want to?
I'm hoping to do nothing permanent at this point...

Yes, you can flash back. Not only can you but depending on how you did flash the recovery the phone may revert it on your behalf. I know mine has several times, like any time I reboot. There's ways to stop it from doing that but I don't mind.
To get the stock recovery back if it isn't automatically restoring means flashing an NAND from the Dev section here.
I didn't want to open a new thread just to ask this so I hope it's OK to post it here.
I'm very interested in getting supercurio's voodoo sound and ext4 mod on my Nexus S but I don't need/want the overclocked frequencies and other stuff included on most of the kernels out there. You guys know any kernel that I could flash to get those and keep my stock fequencies?
Thanks

If you flash the Trinity max kernel and do not adjust the clock you will have everything your asking for. This kernel boots at stock and has Voodoo and ext4 built in.

So I used to run the CM7 rom, then upgraded to a ISC WIP. Well, it was pretty unstable, and wanted a stable rom, so tried restoring my old CM7 backup, and now when I turn on my phone, it shows the HTC splash screen, the goes black (screen still on), and won't go past that. I realize now I downgraded the firmware, and you can't do that.
My buddy said I need to get some toolkit and reset EVERYTHING back to stock roms, re-root and all that. So can some generous person link to all that? I see a lot of it in the Inspire 4G forums, but want to make sure I have it all. And after I flash all the stock stuff, can I restore that CM7 backup (clockwork recovery mod)?
Thanks in advance for the help/reply, much appreciated.

You should follow the steps to reinstall recovery, then go to flashing a rom. You only need to go through the "flashing a stock rom" section if you had problems reinstalling recovery. Just read through all the steps and you'll get it.

If you are S-OFF you just can flash a new recovery image and then flash any rom you want. You will have to do it from command prompt...
if you need help in doing that, just let me know...

Glad you got it sorted out, To be honest that is the first thing you do when a rom wont boot. Whenever you restore a backup it is best to wipe first
Where do i get JUST a kernal (Air Kernal 3.9)?
i cannot find it alone and i already have a rom on and id like to not get rid of it.
Im pretty sure you can just flash a kernal over the older one.
anyone have links?
Thanks.

Nick ... it's an easy operation to change kernels. Go to the proper development forum and d/l the Air kernel for your device to your SD card. Boot into recovery, wipe the cache and dalvik cache, and flash the new kernel. Reboot and you should be good to go.

I don't need stock rom I'm trying to flash Codename Android 2.0 which needs ICS and 5.0.2.x and that one click gives stock rom
how do i update to cm9 and staying on 5.0.2.x recovery

You can't update to cm9 and stay on 5.0.
Unlike most samsung phones, we do not have a functional recovery partition.
Even though we do have a recovery partition, and you can flash the recovery.img there, the bootloader will not even notice it.
It will just boot the kernel with the kernel command line argument: bootmode=2
In this mode, a stage1 init has to check if we are booting to: recovery, low power mode (charging), or normal boot (possibly with ota upgrade).
So in a nut shell, you upgrade to cm9, you get whatever recovery comes with cm9.
If you want to flash another cm9/ics based rom after that, just flash it (factory reset/wipe data, of course!). No need to go back to 5.0 recovery.
If however, your IMEI is screwed up or you have a specific reason to go back to gingerbread, use the oneclick that eollie mentioned. Flash it twice to get bootloaders. And then you can go back to cm9 by just 'factory reset/wipe data' and flash cm9 or whatever ics rom you wish.

This has already been discussed in countless places, including the fix in the first post of the UrDroid thread, under the big red boldface letters "RECOMMENDED".
Always take a few minutes to search and browse for the answer, and read the ROM thread before posting a question; since its almost certainly already been asked and answered by others.

Thank you for your valuable suggestion.
I have seen that while i was downloading ROM! but i don't know the importance of that.
and i know only how to flash custom ROM. but really don't know how to flash a firmware?
could you tell me how to flash that firmware?
i must need TWRP recovery?
whether i need flash this firmware before flashing ROM? or after?

If using carl1961's file from the UrDroid thread (as I suggested) just flash in recovery. Not sure, but CWM should work. You must be SuperCID and S-off to flash the firmware.
Can be flashed anytime, doesn't effect the ROM itself. But with flashing anything, I always do a nandroid first.
