Hi, i rooted my phone using the nexus root toolkit with permanent CWM when i was on android 4.1.1. Now i can't seem to update my phone to 4.1.2 OTA.
I did my readings and conclude that i need to manually flash the 4.1.2 update manually via CWM recovery mode. I've downloaded the necessary official 4.1.2 takju update.
So here's the thing...
How do i exactly go about manually flashing that update without messing things up or worse, bricking my phone at the end of the process? Will i lose my data/apps?
Your help is much appreciated!

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nexus, so root is not the question(though i met some problem while rooting 4.0.4 caused by the version of su.zip is out of date ).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.

Hi,
I originally changed from yakujuux to yakuju in order to get from 4.0.1 to 4.0.4 a while ago.
Now I'm trying to upgrade from 4.0.4 to 4.2. I am currently yakuju builld IMM76I. I tried doing an incremental update through CWM and I got an error. I think it's because of the different radios right?
So what would be the best route to fix this? Should I change build's back and downgrade? I also tried installing the official stock ROM but that didn't work either.
Any ideas?
Going through some folders I just saw one of a build backup when I changed it before.
How do I use this backup?
These are the files I have...http://i12.photobucket.com/albums/a210/ruckus17/scrnsht.png

you can't update from 4.0.4 to 4.2.1 through ota

When trying the incremental updates, I had downloaded the files and ran them through CWM, not actually through OTA.
I tried the google factory image through CWM and also through the Gnex toolkit, again with no luck.
I have the system update notification on my phone, but everytime it goes to install the update, it fails and displays the android logo with a red triangle in his chest.
Like I said, all I did before, was unlock the phone and change from yakujuux to yakuju to obtain 4.0.4 without root. So that's all I can really think of why it isn't installing any updates. My Gnex is now rooted and unlocked.

who said anything about cwm or a toolkit???
I had meant I had tried with the toolkit and CWM before trying the link you posted.
The return to stock method worked. Thanks!
Hi! I was having and I still have troubles with loosing of data signal in some areas when I have 2G only. I unlock my bootloader, put CMW recovery and put newest radio but it didn't help. But I saw that 4.3 Jelly Bean has comed and I didn't get OTA update. I didn't changed stock ROM and I didn't root my phone. Will I get OTA update or because I did things that I describe earlier I will need manually update to 4.3? Thank you.

The update IS possible OTA. It does not show up in KIES for some reason.
A couple of things before you do this.
Be aware that once you have the MJB bootloader that comes with the 4.3 update, you cannot go back to anything lower without bricking the phone. Plenty of articles here about it. Until someone here finds a way, it's a one way trip, and there is no stock firmware available yet to flash via Odin. I'm also not sure if you can load one of the other 4.3 versions found here without bricking it after the OTA 4.3.
Some new features are added in 4.3, and some are broken. For me, after the update, s-voice no longer works via Bluetooth, and I'm pretty sure it is an S-voice and not BT issue. Others are reporting battery life issues, constant updates, etc. Research research research. (I wish I had)
Go to settings - about device - software update and follow the prompts to get an OTA. I don't think AT&T is pushing it, but is available. Probably not a bad idea to boot to recovery first and wipe the cache before you do.
You have to be running a stock recovery for it to install and its about a 1gig download, so be on wireless and have a fully charged battery.
In my case, I had the phone rooted with a toggles mod. The update went partially and broke some things. I had to flash to an unmodded unrooted 4.1.1 via Odin to get the update to go.
I made the mistake of trying to flash MJ2 bootloader after having the MJB bootloader. It boots now with the "unbrick" sd card. Would it be possible to ODIN stock 4.1 and still boot with the SD card so it could take the 4.3 OTA again?

I don't know. I've never bricked a phone. As I understand it, 4.3 BL blows e-fuses making it impossible to downgrade. If that is in fact an accurate description, then even if you were to get it to boot via SD card and installed 4.1.1, it would brick it again (double brick?)
Considering the dangers involved, I'm afraid to even sideload a different MJB 4.3 on mine.
You might just have to suck it up and send it off for a J-tag service. I've never done it, but I think others here have.
here's the link I've seen most.

I am trying to learn more about it but my "initial" understanding is that the "blown efuse" thing is that you can no longer boot from an earlier bootloader but it doesn't "damage" anything else. Therefore, since I already have a phone in that state but it can boot off the SD card I'm wondering if it doesn't make things worse to flash a 4.1 stock image. It would still fail to boot via EMMC but then boot off SD? Then the OTA could "possibly" happen? I doubt it is possible or someone would have posted about it but I haven't seen that you definitely CAN'T do it so I am continuing to look.
Hello all, I'm new to this forum and I could really use some help with my phone. I have a rooted AT&T Samsung galaxy S3 running on 4.1.1 stock with cwm. I would like to update to the latest stock OS which is 4.3 but I'm not sure how to do it right. I would prefer to keep all my data but I don't mind losing root. how should I go about updating my device safely?

If you are rooted then you can flash any 4.3 ROM in the android development and they all have KNOX free bases. You will most likely need to update your baseband to MJB. Enjoy your KNOX free 4.3!!!

You should first check to see if you can get an OTA update. Some users have reported being able to update OTA to 4.3 even with root. Go to Settings => About Device and check for updates. If you can't get an OTA update, you may try manually updating via cwm via the method posted in the following thread: http://forum.xda-developers.com/showthread.php?t=2658486
Before updating to 4.3, however, I would suggest you ensure you are done with taking advantage of all the opportunities you have at 4.1.1 including free unlock as you would not be able to downgrade the 4.3 bootloader once you've upgraded. If you don't have Samsung Kies installed on your PC, you may install it to back up and restore your data. In other words, you cannot go back to an older version (easily) once you have upgraded.
