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?

[Q] Question going from a 4.4.2 to 4.4.4 rom

Hi all,
I went with the f2fs-all version of slimkat (a 4.4.2 version) a while ago and everything was great. Now looking to go to a 4.4.4 f2fs rom (probably still slimkat but maybe another) and was wondering if there is something special I must do. I know on some phones you need to take the ota, then you can go with newer versions.... but not sure if that is just to get the latest radio.
My plan is to tibu, then pull that to my pc. same with a nandroid. Then totally reformat in f2fs the 3 relevant partitions. install new rom, possibly kernel if not included with rom. re-copy my backups over and restore. Am I missing any important things? Do I need to go back to a stock rom and non f2fs-all recovery and grab the 4.4.4 update from google for any reason first?
Thanks all.

no need to take the OTA
the boot-loader did not change
so just do what you need to do to change to a different ROM

[Q] Bump questions...

Hi guys, I am a normal user who like to flash roms and kernels as dorimanx has bump his kernel I am wondering, how am I supposed to flash the bump recovery over KK bootloader? The same way as we use to do it on jb? With flashify? And, about roms, the rom I will going to flash has to be bump? Or once I have a recovery I can flash anything?
Thanks in advance

i would like to know this too...
and what's the advantage of bump anyway?

The advantages are that you don't need to use autorec you just can flash without anything else like on jb that means that (in my case) don't need to restore a KDZ flashable zip to go back to the original phone model because autorec change it....

i still don't see the advantage unless i'd go full stock again (and i don't think that will happen)
i was wondering are there any advantages to the already rooted devices with custom recovery and kitkat roms?

As I know there's no difference for those

[Q] How to Upgrade to Lollipop from CM12 (Tmobile D801)

I have a D801 (Tmobile G2) and I’ve been running CM11 on it for over a year.
Now that we have lollipop, I want to upgrade to a ROM based on the official Lollipop release, (this one: http://forum.xda-developers.com/tmobile-g2/development/rom-tmo-lp-extreme-v1-0-4-16-15-t3084681)
Ofcourse I’m rooted and have a custom recovery installed, specifically ClockworkModv6.0.5.0/Philz Touch 6.48.4)
Can anyone please guide me on how to install the Lollipop ROM mentioned above. I’m thinking the first step would be to update my recovery to a TWRP recovery…. How do I do that?

Flash the TWRP.zip inside the CWM recovery,then reboot the recovery.

And then I just flash the Lollipop based rom? Even though I'm on CM11 (kitkat)?

That depends, you might need the latest bootstack for the new CAF-based roms, but not everyone seems to agree. I would flash it anyway though, this would prevent any issues like sound bugs and anything else you might find.

Can you downgrade to a custom ROM if you're rooted and already updated?

Hey guys, everything I've read has said once you update beyond 4.3 you can never go back down because of knox. I also saw someone mention you actually can downgrade to a custom ROM based on a previous build just not to stock. Can anyone clarify this for me? I'm not worried about breaking my warranty since it's long since expired. I'm on the rooted 5.01 Goldeneye ROM and want to go back to a 4.2 ROM. strictly for tethering purposes

What is the model # for the s4?

It's the AT&T sgh-i337

With a locked bootloader, the phone is limited to customs roms based off a stock Samsung rom. Aosp and cm will not install or run.

Thanks for the reply! So if I stick to TouchWiz based custom roms I can downgrade without bricking my phone?

Yes, just don't touch the bootloader or modem.

Ok thanks. Can you suggest a good 4.2 ROM? Also, since I'm already rooted with safestrap, do I just wipe and flash the new ROM or do I need to install a different version of safestrap and kernal etc? I'm have trouble finding any instructions on how to downgrade. I appreciate all your help!

I can't recommend any 4.2 roms as I don't have the phone. Also, I don't think such an old rom will work on an lp modem and bootloader.

Ok so based on your statement "I don't think such an old rom will work on a lp modem and bootloader," does that mean you actually don't think I can downgrade?

You can try but I don't think you will have a functioning phone in that the imei will not be properly displayed which means the phone wouldn't be able to connect to the carrier.
