[Q] Rooted, unlocked, and OTA updates

Question about whether I'll get OTA updates on my phone after rooting and unlocking.
I read that if the system folder is modified that will prevent OTA updates. But I'm not sure if I had done anything to modify that folder.
I unlocked and rooted the phone using the Wugfresh Galaxy Nexus Root Toolkit v1.3.
http://forum.xda-developers.com/showthread.php?t=1454314
Then updated CWM with ROM Manager.

I'm curious, too. I suppose I'll find out sooner or later since I have two Nexus at my disposal. Both unlocked, only one with root.

i have heard that you will have to flash updates if you are unlocked and rooted. So your best bet is to flash it through CWM.

I wonder if the radios get flashed with the stock updates? I did flash the leaked 4.0.3 radios and have had much better connection negotiations.

Try searching, there's a big discussion in one of the threads in this forum. It's not as simple as yes or no...

Yeah, I had seen this brought up in other threads. The answer usually didn't seem clear as you mentioned. So was hoping for clarification.
Sounds like I'll just have to wait and see then.

I really recommend the other thread, and ask questions there - no one wants to repeat that debate all over again, so I'm not even gonna start...

I found out that one MUST be on the stock 4.0.2 radios in order to flash the 4.0.4 update successfully. I have not tried yet but it is good to know. The radios are definitely flashed (updated) in 4.0.2.

You can be rooted and unlocked and still get OTA updates as long as the OS is still stock. You will lose root but you can get that back by rooting again. Running a custom ROM will change that though.

Which is the best/fastest/easieast way to get the stock recovery back? After unlocking/rooting/CWMing , the stock recovery got erased and not renamed. I guess it differs form GSM to CDMA , so if anyone could help me out here (GSM stock recovery wanted) I would appreciate it..
thanks a lot.

http://code.google.com/android/nexus/images.html download the right version from the google factory images. extract the file.
Then search for the image zip, extract the recovery.img.
Then boot into the bootloader and fastboot
"fastboot flash recovery recovery.img".
This will put the stock recovery back onto your device.

thanks a lot mate...already figured it out..

Clear Answer For Unroot So I Can Update OTA Please

I keep getting the new OTA IMM76I update for my Sprint Galaxy Nexus and every time it downloads & starts to install it just opens up TWRP recovery and nothing happens...
I tried to use the Nexus Toolkit as well and do exactly what it says but get hung up on "waiting for device" after it extracts the files and everything...
I've been searching for 4 hours to try to get this update done because my calls keep dropping...
is it because I have the Franco Kernel installed on a rooted device?
no ROM or anything, just rooted with the Franco Kernel...
I tried like hell to find the stock kernel but couldn't...
DAMN this is aggravating
could someone PLEASE either explain or point to a link where it explains how to deal with this issue?
HATE having a brand new phone and the calls keep dropping....
I know there are "lots of threads on this issue" already but none clearly explain how to fix THIS issue...
please hep me out...thanks in advance.

While the above link is for how to manually install updates, the reasons why an ota update won't install are the same: if you want it to install ota, you need: the stock kernel, stock recovery, stock radio, and stock rom (with no original files missing/modified). Additionally, all of these have to be the same version.
Maybe you could also get the ota update file name for us as well.

does the stock radio stay the same after root?
like I said, all I changed was the kernel...so I'd have to flash the stock kernel to install the update, correct?
another issue I'm having is damn CWM....I have TWRP on here now and when I go to flash CWM through ROM Manager it get all the way to the end, freezes then fails...can't seem to get CWM installed for my life.
also what is all this "yakju, takju, etc..."??
I'm new to this device from an Evo 4G where we just download & flash and all updates work..never had an issue like this.
my device is v4.0.4., build Imm76D.L700FC12
baseband L700.05 V.FC12/L700.FC12
on the bootloader I saw "toro" on there so I'm guessing that's because it hasn't been updated, correct?
thanks.

If all you changed is the kernel, then all you have to do is flash the stock kernel.

would you have the stock kernel?

Try the GN root kit. You'll find it in the dev section. That will get you back on stock kernel.

You need to have stock recovery too.

[Q] any difference between factory 4.0.4 or OTA to 4.0.4 from 4.0.2?

hi i just upgrading my phone from 4.0.2 to 4.0.4 imm76i (gsm/hspa+ without google wallet),
i am going to root the phone by cwm recovery, then i have some questions:
when i was on 4.0.2, i rooted the box by cwm, and when i want to do update by OTA, i have to refresh back to the original recovery in the factory 4.0.2 image to apply the package, and that's what i have done...
so here is the question: if i root it by cwm again, and then flash the new recovery.img from factory 4.0.4 image download from "https://developers.google.com/android/nexus/images#yakjuimm76i"
to the phone, will it keep the ability to OTA to next android version? in another way, is there any difference between OTA & factory image OR, is there a identification to know that whether this device flashed a factory image or ota from a previous version?

ok, then if do not mv/rm /system/recovery-from-boot.p after flash cwm(for root), will it restore the stock recovery and keep the ability to do OTA?

The ota is usually just the parts of the rom that have been updated, those image files are the whole rom, if u root u will be able to get the ota but it won't install even with factory recovery,I haven't done it since my N1 but if I remember right u can delete super user from system app folder and delete,--- com.noshufou.android.su and reboot and root should be gone then ota will work and after u update u just root agn .... but your way u did it is always an option ....

thank u for response, i tried to update to 4.0.4 from rooted 4.0.2, and everything is ok.. according to your condition, i think there may be some difference between nexus S and galaxy nexus, so root is not the question(though i met some problem while rooting 4.0.4 caused by the version of su.zip is out of date ).
now i am on 4.0.4 and rooted by cwm, and i didn't delete /system/recovery-from-boot.p, i hope that i will not have to re-flash stock recovery when the next OTA come

When you say that is rooted through CWM, means what exactly? You only used the CWM to root the device? But how?

yep cause i wanna use stock rom on my GN so far, so i use cwm only for root(by flashing a su.zip), and after googled a lot, i think it has went back to stock recovery now, no longer worry about OTA, thank you

No difference. If you did not delete the two files (/system/etc/install-recovery.sh and /system/recovery-from-boot.p) then your device will automatically flash the correct stock recovery on every re-boot.
EDIT: Actually there is one difference: the OTA places those two files on your system, while a full stock ROM does not.

This is wrong. Rooting has no impact whatsoever on being able to install an OTA update.

if i flash update file from takju 4.0.4 to 4.1.1 through cwm with just unlocked bootl

if i manually update from 4.0.4 takju to the jb 4.1.1 through cmw, will i still get OTA updates in future. also, if the i do the update, will it lock the bootloader and erase cwm? thanks

OK to get a few things right here, you need to have stock recovery to install OTA, no it won't relock boot loader, yes it will erase CWM. Your rom needs to be 100% stock (including boot loader, kernel and radio aswell as rom and recovery).
The way I just went to 4.1.1 (takju) I was running the preview JB Google IO rom anyway so in CWM I reflashed that to undo any system changes I made. Then using Mskips nexus tool kit I used it to flash stock recovery and then BOOT (NOT FLASH) to CWM. Find the update and flash it. Before you do all this use titanium to back up your stuff, do a nandroid and get voodoo OTA root keeper so you get root back after the update.
Then using the tool kit again I used it to flash CWM back. Then your done. I won't give further instructions but for further reading efrant has very good posts about this stuff, mskip has very good instructions on his tool kit in the thread

i'm still a little confused. my phone is completely stock. it's a takju 4.0.4. i don't want to wait for the OTA for jb 4.1.1. i was going to use the nexus tool kit to unlock the bootloader ( i believe that's required to boot it into cwm) then run the OTA update that people posted for my version to update it. I don't care about keeping cwm or bootloader, just want the update now and keep the phone still stock. i also want to make sure that i'll get OTA updates in the future. It looks like I can just boot it into cwm without flashing it, so that's what i'm going to do.

Yeah you can but you need to unlock the boot loader to do it, which wipes your entire phone so back up any thing you want to keep like photos or music. When the bootloader is open you can just leave it and just lock it if you need to send for warranty. Or if you already have root but locked boot loader there is a free app to unlock it on play store

once, i update the file using the nexus toolkit to boot into custom recovery, once it updates, it will lock the bootloader and the phone will be back to stock right? or is the bootloader going to stay open.
also, will i still get future OTA updates if i just do the update by booting into recovery and not flashing cwm?

Once you unlock it the bootloader stays open until you choose lock I again. You can still get ota but remember you need the matching bootloader, kernel, radio and unmodified system and recovery. So just booting cwm is fine to apply and then after its applied the patch you can flash what ever you want again. I find its always a good idea to make a back up of a 100% stock rom and keep it on the pc just in case. This is all simple and quick with the tool kit

Hey, first, thanks for the replies. Second, if I unlock the bootloader to install update, make no other changes, meaning everything else is stock and the update is googles stock update, them once the update is done, can I run the toolkit again to lock the bootloader. Doing this will it bring my phone to same everything as a stock ota updated one? Or is me unlocking and then locking bootloader going to cause me to have a different version for the next ota

No worries its fine. Yes after you have successfully applied a stock OTA patch onto a stock rom then you are running the same as everyone. Their are minor regional differences, like takju and yakuto (what ever lol) toro, toro plus etc but flashing a ota patch from a different build won't work on a rom that doesn't match.
You can go to the Google developer site and search for the full ROM and you know definitely its 100% as its meant to be, the patches just write over the bits which change in updates. The thing to bear in MIMD about flashing the whole ROM from Google site is that it will wipe your entire phone

Please Help! How to restore from backup on laptop

I am a n00b.
Just today I changed my phone from yakjuux to yakju, and it all seemed to go smoothly.
I am receiving texts, and everything seems to be working, and when I was trying to update to jelly bean OTA, everything was going well, until a little red triangle popped up over the little android, and my phone restarted with no change. I flashed my original radio image (UGLA4) so Im not sure whats up with that. If anyone has any suggestions about how I can fix this it would be greatly appreciated.
If not, I would like to restore my phone to yakjuux using a backup I made using this website: http://forum.xda-developers.com/showpost.php?p=21266325&postcount=239 as a guide. I have all the files saved onto my laptop, but Im unsure about how to use them and restore my phone to its original state (yakjuux)
Many thanks

You are seeing the little red triangle because you have an image that is not stock. You need to do the optional steps to get the ota (i.e., you need to flash the bootloader, radio and recovery). Go back to the convert to yakju guide and do them.
P.S. why did you not flash the JB images instead of the ICS images??

I flashed the bootloader, radio and recovery(I probably should have mentioned that in my initial post). Do I need to download a new image to flash onto my device? And how can I tell if its stock? I got my factory image from the link from your guide.
Im not sure why I didnt flash the JB images... I'll blame it on my n00bery.

Will there be any problems if I follow all the steps in your guide, and pretty much redo everything? I would flash the bootloader, flash the same radio (UGLA4), flash the data paritition, flash the system partition, flash the kernel and flash the recovery the only difference being that I would use the JB image rather than the ICS image.
Thanks again

There will be no issues. Note that if you flash the UGLA4 radio, the next OTA update will not install. You will need to flash the XXLF1 radio before attempting to install the next OTA update. (That is probably why you are seeing the red triangle -- the OTA is expecting to see the XXLA2 radio, and it is seeing the UGLA4. If you want the update to JB to install, just flash the XXLA2 radio, and the update will install.)

After updating to JB, I got prompted to update the OS to 4.1.2 and tried the OTA. For some reason it worked even though i wasn't using the corresponding stock radio image, and now I'm being prompted to do another OTA update (4.2.1). Seeing as the OTA worked last time, I tried to do it once more with the 4.2.1. update, but i ran into the same problem as last time: a little red triangle appeared over the little green android. So I did what you suggested, and flashed the xxla02 radio, and then tried to install the OTA but the little red triangle appeared again. So my question is; are there new corresponding stock boot, radio, and recovery images for JZO54K? If so, i probably still have the boot, radio, and recovery images that were stock to JRO03C.
I figure that if i flash the new stock boot radio and recovery images, the OTA should go smoothly. Any thoughts? Or should I just manually flash the 4.2.1 update that i can download from the google developers website ?

Not all updates will update the radio or boot images, but some will. If you are on 4.1.2, for future updates to work, including 4.2.1, you need the boot, recovery and Radio images from 4.1.2.
