No. No. No. You will lose root access after the update. You will have to re root. And which stock kernel do you want to flash back to? 4.2.1? Maybe I don't understand your question..
If you're saying when your device detects the update and you want to flash back to its factory stock kernel, then yes you can do that.

Cheers for the input
i was just curious of when the update comes to my nexus 7 that i will have to return to stock kernel so it updates with no issues because of running bricked kernel. I have also installed vodo root keeper (think its called not with my n7 at the moment) to help me keep root. Will i be able to flash the ota through cwm with verification signature turned of ? Or do i have to install stock to flash it

Ummm... the OTA process performs binary patching on individual files. If a file is not a target of the patching process, nothing happens to it. So that beggars the question of why you think that Superuser.apk/su (or SuperSU/su) would be targeted, as they are never distributed by Google. More to the point, neither of them exist in the boot image, so your assertion is flat out wrong.
Also, a sanity check (checksum) is performed on each and every one of those targeted files; if it should happen that there is an update to the kernel or ram disk, then the boot image will be checked, and IF you have installed a new kernel (or even have a trivially changed boot image), the check of the boot image will fail and the entire OTA will abort.
So, the OP's question was not only perfectly valid and reasonable, but exactly the correct procedure if the boot image gets patched by the OTA.
I'm planning on doing exactly what the OP suggested; but good Dog, I'm also going to do a full Nandroid backup before I begin. How wrong can things go if you have a backup to revert to? (In fact, I'm even going to put the stock recovery on the tab for the purpose of the OTA too - if you have an unlocked boot loader you can reflash or soft-boot any recovery you want, and do whatever you want thereafter.)
Even if you were to "lose root" you can certainly just over flash a minimal kit containing Superuser.apk/su. It's not a big deal.
Put down the toolkit and the hash pipe, and pick up the command line!

How to update android version when on a custom ROM?

So I am using CM10.1 with CWM recovery. What will I have to do when a new version of Android comes out? (4.2.3 or 5.0)
And will I lose my root access?

Either flash a new ROM that's built on the new version, or go back to stock.

And to flash that ROM, do you have to get new bootloader and baseband or what?
And go back to stock: do you mean to flash the factory image, or can you also get OTA updates by restoring a nandroid backup of the stock rom?

once you are rooted, unlocked and with custom recovery changing ROMs is as simple as puting zip onto your devices' internal storage and flashing it through recovery. you COULD be asked to flash a newer radio version, however it is not that common.
no OTA when rooted, going back to stock only with facotry images.
anyway 5.0 will be availabale on custom ROMs shortly after or even before official google OTA so no need to unroot.

So when 5.0 comes out, I just have to wait a day and flash a new CM version without flashing a new bootloader or radio?
And will it directly be stable?

Android 5.0 is far away by now, and nobody can tell you yet about stability
i´m sure it will get announced, just check the CM thread and read about (possible) bugs

As long as you read threads properly you'll know whether or not anything extra needs to be flashed. Even if there is something you need to flash in the future, it should be fairly easy. Normally a flashable .zip is released soon after the official release so you won't even need a PC. Personally I think it's useless to worry about it right now.

Radios and boot loaders are completely separate from ROMs. You have to specifically flash a radio or boot loader separately. But no, you should not need to flash them but it would be worthwhile if a newer version came out

I am a bit scared of flashing bootloader and baseband, because I read someone who flashed a wrong one and his phone completely got bricked. Some other guy said in that thread why would you manually flash a bootloader..

If I restore my Nandroid backup of 4.2.2 stock ROM, am I able to get OTA update? (I dont care if I would lose root, the question is if its possible ) or is it impossible since I am running CWM recovery?

If you are going to flash custom ROM; use a toolkit to Root it; flash custom recovery of your choice. Then copy custom ROM to ur phone; go to recovery and flash it. You don't need to downgrade your boot loader.

Does this mean we can downgrade from 4.3 to 4.2.2 custom ROM?
I'm not having a good time with 4.3 stock rooted and custom kernel and thinking about going back to CM 10.1.2. All I need to do is flashing the custom ROM in recovery?

Yes you will be fine. Before PA 4.3 rom was released, I was using Latest 4.3 bootloader with 4.2.2. I am going to revert to 4.2 as well. I noticed 4.3 battery is really good but sometime touchscreen doesnt response / volume buttons doesnt work.

for unresponsive screen go to 'developer options', 'hardware accelerated options', 'disable HW overlays' and select 'always use gpu for screen compositing'. Works for me but setting doesn't seem to stick on reboots.

^^ oh okay thanks but I am already back to the good old 4.2.2 .

Hi I´m quite new to this and did recently flash my second custom rom. I went from CM10.1 (4.2.2) back to stock image, and flashed
[AOSP]Official 4.3- S4 Google Edition- Finaly v2.0 - Feel the Experience of Nexus. The phone is running hot and I´m kind of dissapointed with the
lack of tweaks in Google Edition. So I´d like to go back to CM
So if I understand you right I can from 4.3 flash my stock image (from TWRP) which was on 4.2.2? Without worrying.

Did you make a nandroid backup when you were stock? That should be the easiest way to get back to stock. If you didn't then you will need to use odin to flash back to stock.

you have made alterations to your phone so its not longer stock. the file you are flashing is for a stock rom and to be flashed in a stock recovery. to flash the update simply re-flash a stock recovery and allow the update to go through. you can also simply wait and flash an updated custom stock rom.
Edit: link deleted....may confuse you
Edit2: Using the toolkits you should be able to find the stock recovery image and flash it back

Can't flash new rom after flashing 4.4 rom.

I flashed a Kit Kat rom, and before I was having problems with recovery. Now I'm having problems flashing a new ROM. Every time I try to flash a different rom, it says it flashes but it just goes back to the 4.4 rom I flashed first. I can restore a backup just fine, but even from the backup it does the same thing.

My MAC address keeps changing after reboot, and wifi is screwy no matter what I do. Full Wipe, factory reset, Factory image restore. Its seems the 4.4 roms change things that cant be undone. I now have to have my phone replaced.

Gah. I'd rather not have to have my phone replaced. I feel as if its just 4.4 ROMs though.

Try reflasing your recovery. If that doesn't work, then flash the 4.3 factory images.

I'm on the latest CWM touch, I believe 6.0.4.3. I haven't actually tried going from the 4.4 rom to a 4.3, but I know I can't go from 4.4 to a different 4.4 rom, or from 4.3 rom to a different 4.4 rom, it just goes to the first one I flashed.

GooManager is telling me that there is no recovery available for my device. That's odd.

If all else fails, download the stock 4.3 image and fastboot flash it, then try whatever other ROM you wanted.

The only other thing you might try now is flashing any 4.3 or 4.2.2 ROM, reboot, and see if it's now on that one or still on 4.4...
Or is that what you already did with PAC?
You can also manually format /system then /data from TWRP or CWM then manually flash your new ROM.

That's what I did. I went from 4.4 to PAC, and it booted into PAC. Same with CM 10.2. It seems to just be happening with 4.4 roms.

I just wiped /system and /data, and now the 4.4 PA fails to flash, but CM 10.2 flashed. I'm gonna switch to CWM to see if it'll flash there.
UPDATE: CWM would NOT let me go back to the previous option when asking me to reflash recovery when booting, and it didn't flash PA, so now I'm stuck on the first 4.4 build with no GApps until 9 or 10 tonight. First thing I'm doing when I get home is flashing the factory image.
