I have a rooted GNex and don't want to wipe the sdcard in order to re-root after the 4.3 OTA update.
My phone already got the OTA update, but I haven't yet allowed the update install to run. If I unlock the bootloader before letting the the update to be installed, will the bootloader still be unlocked after the update?

GNex GSM (maguro), takju build
Bootloader PRIMELC03
ClockworkMod Recovery v6.0.2.3

First, what do you mean with "wipe the sdcard ir order to re-root after the 4.3 OTA update?
Second, unlocking your bootloader WILL wipe your internal storage. After unlocking it your phone won't have any files besides the system one. All your personal files WILL be erased and your phone will perform a factory reset. You'll have a phone just like a new one. I read somewhere that there's an excetion to this rule, you could try searching for this excetion, but I don't remember seeing it anywhere after, so it's probably false.
But, answering your question, OTA updates (in the nexus case, at least) won't re-lock your bootloader. After unlocking it'll remain unlocked until you yourself lock it again.

Root is lost after the OTA update, right? (I read that somewhere.) If the OTA update also locked the bootloader, I would have to go through the bootloader unlocking process (which wipes all the sdcard, as you just described) to be able to regain root.
You're using a Nexus device, of course it doesn't relock
Thanks. I've already installed the OTA update. Root was indeed lost, but the bootloader remained unlocked, so I was able to re-root the phone without wiping my data.
Even if it did lock your bootloader, you could unlock it with this (provided you have root of course).
You could even unlock your bootloader with Omap Flash.

The salient point being, it doesn't re-lock the bootloader.
Root WILL be lost, but 4.3 can easily be obtained again on 4.3.

Hello,
i have a Galaxy Nexus "yakju" still on 4.0.2
i have opend the bootloader to able to make full dumps with cwm (without flashing it), but i got no ota update. i tried to delete Google Services Framework Data, but with no success...
Just flash the update, since you already have your bootloader unlocked. Files have been available for weeks.
Hi martonikaj,
i know that way to flash the OTA file via /cache, but my question is more in general. has google stopped the OTA? why i don't get it? couldn't find any usable info about this. May the bootloader locked to get OTA updates?

No, your bootloader doesn't have to be locked to get the OTA. Your radio, build.prop and complete footprint need to be proper to receive it though.
You don't use the /cache mode. If you have an unlocked bootloader, you just boot into a temporary CWM image and flash the update with Fastboot. The update will wipe that CWM and you'll be on stock 4.0.4.
I downloaded the OTA files and flashed it with stock recovery...

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

Just got my S3. Should I take the initial OTA or will that make it harder for me to root?
I've done my initial homework by searching but I'm still a little unclear. I'm so accustomed to HTC with their OTAs changing Hboot and preventing s-off, etc. I found the guide on how to root but does the bootloader need to be unlocked?
This is my first Samsung device so please be gentle to this noob.

Your safe to take it, initial root process will be the same regardless. You'll most likely root flashing cwm recovery or a insecure kernel in odin so the system wont matter.only the vzw model has a locked bootloader. doesnt apply to us
If you are at n00b status i personally reccomend mskips toolkit found here:http://forum.xda-developers.com/showthread.php?t=1746680 ---guys a genius, has everything you need.
you can't OTA update a phone that's rooted or has CWM on it, so definitely update before you root.
Exactly, it will download but will fail on the install because CWM is installed. You must have the Samsung stock recovery installed in order to update. Depending on what ROM you are running, you can re-install stock recovery, install OTA update, re-install CWM, then root again. That is what I did, but I am running Rooted Stock.

Really the ota's don't matter ne way as the only important parts are the modems which can be dl'd here and applied in cwm anyway
Thanks fellas. My only concern was with the ability to root and staying unlocked after taking an OTA. I'm traumatized by the EVO 3D's OTA that updated the Hboot and was just a pain in the ass.
What's the current OTA address anyway?

Hi,
I have the AT&T S3. I took the OTA update to NJ1 now. Does that mean my bootloader is now locked and won't be able to root? and install custom recovery?
The i747 (AT&T) does not and has never had a locked bootloader.

Your bootloader has been updated, but as Audit13 said, no, the bootloader is not locked. You should be aware, though, that you should not try to downgrade your bootloader to a previous version. (I.e. after some times if you attempt to return to stock ROM using ODIN, you should not install a build previous to NJ1.) Except for that, you will still be able to install a custom recovery, root and flash custom ROMs.
thanks guys much appreciated! happy new year !
I have lg g4 that i bought used, i had it for a while and wanted to return it to stock, from what i understand i has stock rom, but the boot loader is unlocked and its rooted, is there a way to return it to stock without losing data? Will i be able to just unroot and lock bootloader?
You can unroot by flashing kdz, but you cannot lock the bootloader.
You should have look into it before buying it.

If you want ota updates you shouldn't root your device.
Just use the latest KDZ to update, or unroot your phone and wait for ota.
You can try to unroot on supersu app,there it should be an option to unroot, but best thing is to use kdz.
