I asked this questions in other threads, but i received literally opposite answers, so i decided to make a thread and explain my situation.
I am a noob and i installed twrp recovery and sabermod rom,before installing sabermod i made a nandroid backup of stock 4.2.2 rom,as you all know android 4.3 will be released soon,and i got some question:
1)If i restore my backup of stock 4.2.2 will i be able to update via OTA even if i have twrp recovery ?If yes will all be updated ? (radio,bootloader,rom ecc. ) and will i keep my custom recovery ?
2)If the answer to the first question is no ( i won't be able to update via OTA with twrp recovery) how can i update to 4.3 when it will be released?
A nandroid backup does not restore the bootloader or radio. Only system, data, and boot.
If no other modifications are made the ota will go through with a custom recovery.

Yes i know that a nandroid backup doesn't restore bootoader and radio, my question was if an OTA will update bootloader and radio in addition to the rom, i guess yes right ?
In your thread i think to be in scenario 2, so i need to flash the ota via custom recovery instead of getting automatically updated like in stock rom ?
If the ota has a new bootloader and radio it will as long as your have the up-to-date versions installed.

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?

Hi,
I am about to flash the PA rom on my N4 but before doing that I need to know how easier I can come back to my stock setup.
I have made a complete nandroid backup but I am not sure if that will work. My baseband and bootloader are already latest versions so that's that.
Actually I'm not sure if flashing the stock rom back is the only way so need to confirm that.
Thanks!
You can either go back to stock by flashing the stock nexus 4 images, or by restoring your nandroid backup that you created while you are on stock ROM.

Or you can simply download the deodexed stock 4.2.2 ROM and flash it via recovery. Just wipe cache and dalvik cache.

But it isn't really stock because he won't get OTA's if the rom is deodexed, right?

If you flash a stock ROM from XDA whether its deodexed or odexed it won't install ota because its signed differently

Thank you so much for your helpful responses, I was able to "test" and successfully restore my previous setup using a nandroid backup so no need to flash stock images/firmwares
So, we have two options when we want to go back to previous rom:
1. Either flash a factory image as mentioned (which erases all the system data etc etc)
2. Make a nandroid backup before installing a custom rom and restore the backup if youre not happy with it
Cheers and Thanks again! :good:
I rooted my N7 (NE370T) a few months ago but can't remember how I did it. I would now like to flash a stock 4.3 ROM to it, and was looking for the safest way of doing it while retaining root. I have CWM 6.0.1.9 installed - would it be easiest to install a flashable stock rooted ROM zip from CWM? (e.g. http://forum.xda-developers.com/showthread.php?t=2376881)
I'm currently on v4.2.1 (JOP40D)

Yes it would be easiest to flash a 4.3 ROM actually. I went the way of Clean ROM 4.0 and faux kernel and I don't regret it. It came pre rooted and optimized. Though as always you should make a nandroid before you flash anything.
Also, make sure your bootloader is up to date if you have problems flashing a 4. 3 ROM

Sorry for the dumb question, but how do I check and update my bootloader version??
Check the dev section for the latest bootloader. As for checking, you'd have to use commands in fastboot and I'm sorry I don't know them. Basically what I would do is just do as I said in the previous post. If things don't work, then it's obvious you'd need to either update Cwm or your bootloader or both.

You might want to have a look at my blog, there I described a very easy way for updating to 4.3
Boot loader version comes up in the bootloader screen ( vol down + vol up + power while tab is off ) .. And to flash the bootloader
Code:
fastboot flash bootloader bootloader.img
4.23 is the latest version for bootloader.

Thanks for all the help. I managed to successfully flash a pre-rooted 4.3 stock ROM from a zip using CWM recovery. I suspect that my bootloader may not be the latest but everything seems to be working OK so I guess it's OK to leave it.
Hello!
I recently had Xposed Framework installed. I uninstalled it to get my phone ready for the Android 4.4 OTA.
I have a STOCK ROOTED Nexus 4 with CWM Recovery (Bootloader: Unlocked).
I wanted to download the Android 4.4 OTA once it is released.
Based on what I understand, there are two ways (that I prefer) of receiving this:
1> Unroot the phone and put stock recovery. I had a question with this method:
a: Would I need to lock the bootloader to install the OTA? If yes, on locking would I loose my data?
2> Flashing a binary that would be released on the Google website. I also had a few questions related to this:
a: Would I loose my data if I did so?
b: Do I need to make any changes to my Stock Rooted Nexus 4 with CWM Recovery to follow this method?
Which method would you follow? Or do you have a better method? Please help me out :laugh:
Thank You!
Just go to the ota help desk here on xda and once the ota is being released they will put it in a zip file and you will be able to install it in recovery without losing any data, so just like a normal ota.

That's great. But what if I want to install the OTA? Wouldn't installing something from the OTA Helpdesk void the warranty?

No................................................................. this isn't a Samsung phone.
Can anyone confirm you need to unroot or not to receive OTA? (I have never bothered with it since flashing roms). Just make sure you're running unrooted stock rom that is odexed, stock kernel and stock recovery, as far as I know.
If you flash the factory firmware from Google it will wipe out everything, including your /sdcard/ partition. You could wait for a 'stock rom' that is flashable by custom recovery, these don't delete your /sdcard while flashing, these (unrooted odexed) roms should still be able to receive OTA (correct me if I'm wrong).
Yes u will have to unroot to receive OTA.

I see so many of these threads and then I see the I bricked my phone going back to stock threads next. Please if you enjoy root and the features it brings you just relax and wait out the update. Your favorite developer will then create a nice new KitKat version with your updates and customizations. Of course do what you like but to unroot and get rid of your custom rom to have stock and then re root to try and get the same effect again just sounds crazy too me.
Patience is a virtue
Edit: but your question is what route to take just so you know there are back to stock threads which would be your best bet to follow if you honestly feel like doing all that to undo it later....
I recently realized that I use no root requiring apps or custom ROMs on my Nexus 7(while I keep my phone rooted for many a reason). Now that I hear the 4.4 update is being pushed, it occurs to me that all keeping a custom recovery and root on my tablet does is complicate updates. So I want to unroot, return my recovery to the stock, and get myself all ready to wait for the update to push out. What would be the best way to do this that does not require me to lose data/game saves/have to reset everything up?
Fastboot flash the stock recovery and don't worry about su because the ota will take care of that.

I am sure this has been answered somewhere and I did search the forum before posting but right now i am pretty excited about 4.4 and would like the experts to answer this regarding grouper :-
I got the 4.3 update OTA on a rooted 4.2. I later rooted the 4.3 but did not remove any default apps. I also have frano kernel installed and TWRP recovery. Does the kernel and custom recovery affect the OTA process? Am i safe for 4.4 OTA? or shall i unroot, install stock kernel and also stock recovery?
Thanks
You should be fine if you install the stock recovery before the OTA arrives

Open the SuperSU app on your device.. Go to the app settings and select the option to unroot/clean up.. Reboot. That is all.

Yes, you'll want the stock kernel and stock recovery installed.
On grouper, it can update independent of changes you have made to the system and recovery. This isn't true for all other nexus devices, for example, mako. Doing the 4.4 update will get rid of root for you, but it will flash fine even if you have a custom recovery. You may need to flash stock recovery manually if you don't want custom recovery anymore.

In the past, that has failed for me. I'm still one update behind on 4.3 because it would not install and I was too lazy previously to unroot and get it to install.
