Question about unrooting.

Alright quick story to get you were I am. Seens I got my sgs2 I rooted it and flash a ROM that day. I never did see how this phone is stock or even useed it to compare it to other roms etc.. So I unrooted back to 2.3.5 because I figured that was my stock phone but I really don't know. Ether way the question is shouldn't my phone tell me I have a update for 2.3.6? I have been stock for 12hrs I just thought it would tell me I have a update.

You should, but it would be faster probably to just flash it...

I know it would be faster to do it that way. I just want to make make sure this phone is back to stock. Samsung Kia says there is no update. I am starting to think I am just not a stock phone.
Android version: 2.3.5
Baseband version: T989UVKL1
Kernel version: 2.6.35.11
Build number: Gingerbread.UVKID
now I think this might not be 100% stock and thats my problem. The reason I am asking this is I am going to be sending a phone back and just wanted to make sure it is a close as it can be stock.

Did you odin it back to stock or did you use cwm to flash it back to stock?

Used Odin to flash 2.3.6 ( was stuck with boot loader ), Then flashed in 2.3.5. Why what was the difference?

was just wondering if you did odin or CWM... odin is more true to going back to stock.. if you use cwm you would have to flash stock recovery, kernel, rom, and modem.
but since you're just sending it in for warranty exchange. 2.3.5 should be fine. I sent mine in while it was still deodexed. You can always try to odin 2.3.6 again, try a different port.

Alright thank you very much.
What does deodexed mean? After doing more resreach I found out that that is the 2.3.5 that I am useing as well.
Thank you all with out saying much of anything about my issue you all did help figure this out. For the next person that may be trying to unroot there phone back to stock and wondering why they are not getting a 2.3.6 update this is why.
-This is what I had
Android version: 2.3.5
Baseband version: T989UVKL1
Kernel version: 2.6.35.11

This is stock 2.3.6

Android version: 2.3.5
Baseband version: T989UVKID
Kernel version: 2.6.35.11

My old 2.3.5 was a cross between 2.3.5 and 2.3.6 so I wasn't getting the updates because my phone it was running 2.3.6 Thanks to the baseband.

Update only offered through the kies app though not OTA and may take app little bit to auto detect you can manually start it from tools menu after phone plugged in and drivers finish install.
You have to copy superuser zip and flash on any ROM that is not pre rooted before you get super user and full function.

Please use my advice as advice I am not responsible for what you choose to do with your personal device in any way.
You need to use a stock recovery image and flash with Odin at least
use your original nandroid backup from right before you installed your ROM and right after you rooted
but if you want things like custom install count reset use unroot package (easy Google) as I am unsure if original nandroid would reset this (but most likely will as they are full partition images)
They usually want to see stock recovery menu and ROM and don't normally dig deeper from mine and others experiences.

He did check through kies, but there was no update most likely because his baseband was still kl1

He Odin the stock ROM which includes stock recovery and kernel also. not sure why his baseband didn't change... bad flash? who knows.
If you restore your nandroid that was backed up after you rooted, you would still have superuser install you would want to remove that too.
But yeah he doesn't need to do any of this because he Odin the factory stock ROM that includes everything stock.

Yup phones golden now right to be shipped back.

Got OTA notification but....

...I downloaded the 4.0.4 update and went to install and reboot. But the phone got stuck at the screen with the android belly up and a exclamation point. Pulled the battery and rebooted and was at 4.0.2 still. Haven't gotten another OTA notification. Do I get another OTA alert or do I have to update manually.
I have a GSM Nexus, rooted but with stock 4.0.2. And I activated OTA RootKeeper before downloading the update. Any help will be greatly accepted.

Besides root and maybe unlock your bootloader, did you change anything in your system (install mods, different radio etc. or rename system files)? If you are not completely stock your OTA will not work and you will have to update manually or get back to Stock first.
Sent from my Galaxy Nexus using xda premium

Nothing changed. Except for root and unlocked bootloader everything is stock.
Sent from my Galaxy Nexus using Tapatalk

Well the screen you were looking at (Android belly up) is the stock recovery. If you see that: no need to pull battery. Simply push volume up + power simultaneously and you'll get into the recovery menu. Scrolling through the options can be done with the volume buttons, select with the power button.
That said: I think no one knows for sure but I myself would not wait and update myself. There are a lot of guides here on how to do that and if you flash the stock images you will have the same as anyone who had the OTA. Make a proper backup first (you allways should)! You will lose all your data if you have to unlock your bootloader.

Have you installed CWM recovery installed?
The "belly up" android is the phone trying to boot in the stock recovery to update the phone. But as you may have CWM recovery installed (which replaces the stock recovery) the phone cannot complete the update.
You will need to re-install the stock recovery. I believe you can do this with the GNex Toolkit.

Is it possible to get the Stock Recovery Screen when you have CWM installed? Didn't think that was possible... that it would just boot into CWM recovery. That is why I didn't mention it (trying to learn here).

Same problem here. Stock 4.0.2, rooted, CWM installed.
Does this mean we will lose settings before we are able to update the device?

this mean you are not eligible for the OTA update mate, because you have a custom recovery
i suggest you to
flash the stock rom manually
flash a custom rom wih 4.04 inside

custom recovery is needed in order to install custom ROM dude, is quite simple
and yes, you can root the stock ROM without custom recovery, there are a lot of guide about that in the developer section

So my only option to fix this now is flash 4.0.4 manually (will I lose stuff?) and then root again and get stock recovery back? Sorry for my n00b questions, thanks for your help!

I want to manually flash 4.0.4 and stay unrooted. Should I use the GNex Toolkit to flash 4.0.4 directly or do I need to flash the same version I have on my phone?
Sent from my Galaxy Nexus using Tapatalk

I had the same issue described by the OP, the belly up android when trying to update to 4.0.4 from the OTA notification. I had previously changed to 4.0.2 yakju using efrant's instructions from the first post in this thread: http://forum.xda-developers.com/showthread.php?t=1391881
However, I had skipped the optional sections. In particular step 12 to flash the recovery partition. I went back and just executed step 12 (fastboot flash recovery recovery.img) and rebooted. Then I was able to update to 4.0.4 successfully from the OTA notification.
I'm guessing I didn't have the "stock recovery" because I previously had the default Samsung version?

Just got the update again OTA, and again the belly up droid. I'm really pissed now, bc it also reset my Go launcher... Had 7 screens w/ widgets and shortcuts...
Why did it go wrong again? I thought I put back the recovery to stock to solve the OTA problem... Should I do other things? The phone starts to really slow down and I'm ready to toss this piece of c* in the bin...

I had the same issue just now with my phone (unlocked, rooted, stock revcovery), but a quick reboot allowed the update to complete and I'm now on 4.0.4. Did you check the version number again after this latest attempt?

Yes, still 4.0.2.
And of course, my phone says I'm up to date. Lovely, NAAAAAT!

System Update 4.1.1 Failed

Hi
My phone is rooted and I have the OTA update of JB 4.1 installed . Today i got an System Update from Google and when i clicked restart and install , my phone rebooted in recovery mode of ClockworkMod, then i saw that the update has failed .
I restarted my phone and when i saw that version it is 4.1 and when i selected check for update is says my phone is up to date ?
Please let me know how can i get the update from google now ?
Thanks

??

Manually flash the OTA in the release section. You have to be on stock everything (with the exception of root and an unlocked bootloader) for the OTA to succeed i.e. you will need to have a stock recovery which by seeing that you booted into CWR, you don't have. You can simply boot into CWR rather than flash it e.g. fastboot boot NAME_OF_RECOVERY.img

Relating to flashing the stock recovery? Well you have to be on ICS to update to JB...and assuming your bootloader is already unlocked, you shouldn't lose any data when flashing the stock recovery, radio or bootloader.

I am already on JB. I got via rom from here (xda). So i will need to go back to ics. Is that it?

yeas, it's works perfectly

If you have busy box installed like most people who are rooted it will screw your system files so you can't update properly an you will keep getting the install aborted message, just permanently flash system image from 4.0.4 stock using fast boot or toolkit before installing jellybean.If you want cwm an stock recovery keeps flashing itself back after each reboot you get that dead android screen when trying to boot into recovery ,you have to go to system/ect location in phone an rename the install-recovery.sh to install-recovery.bak using root explorer or whatever an reflash cwm again, I had that problem when re rooting after jb update an trying to use cwm.

My friend having seems red error. After downloading update. And as mentioned here it is xxla issue which has to be stocked.
One quick question though, do I need to just flash xxla radio and reboot or I have to unlock bootloader too?

This is only true if you installed busybox in /system/bin. You should NOT install it there. Installing it in /system/xbin will cause no issues, and it will work properly.

Jb 4.1

To start I am a newb
I Have a galaxy nexus with the 4.1 Jelly Beans ( not stock, installed via ROM from here xda). That's fine. This week a new "system" update was available for my phone. So I downloaded it and the phone reboot, when the phone starts it goes to the cwm recovery screen saying the update failed. I would like to have some HELP, I found other threads, but I really don't want to do anything worng.
My questions:
How can i get the updates to work again?
DO i need to get ICS back to update the phone?
How should i do it?
Can I do that without losing my data ( would be great, but i am ok if there is no way)
I am just afraid if i go back to ICS, and the update don't show up.

Everything must must be bone stock to install an ota.
Jellin' like a felon

The issue at hand here is that you have a custom recovery. I can't say that if you remove CWM that you'll be able to OTA update, but that's at least what was the problem there. Now, if you want to keep all your apps and update to the OTA jelly bean instead of the Google I/O preview build, you can flash this here: http://forum.xda-developers.com/showthread.php?t=1737849
Follow the instructions on that post to update. This is what I did and it worked perfectly.

But going to factory reset will not remove the cwm recovery... right? If i go to factory data reset on my phone ( remember i am using a 4.1 rom) will it go back to ics and delete all roms / root?

PLZ, tell me!! If I do the factory reset is it gonna remove CWM, and all stuff i have installed?

You said you downloaded your ROM from here, but you didn't say which one. There was at least one (Koush's) that was an image of the stock ROM, taken from the OTA update that went out to the phones given out at Google I/O. If you have that ROM (and the corresponding radio), you can just use CWM to install the OTA update. I know this works because I did it myself.
If you really have one of the custom ROMs, your only choice is to return to stock if you want the official OTA. And yes, this will remove CWM and wipe your entire phone (including anything in /sdcard)... so backup anything you want to keep before you try this. See efrant's excellent guide here: http://forum.xda-developers.com/showthread.php?t=1626895

Sorry man, I know i am not giving a lot of information, but that's cause i really don't know. I did a random "how to update your galaxy nexus to 4.1" tutorial, and i don't even remember where...... I just know the links i download were from here.
So what i am going to do:
1: Factory data reset
2: I think it's going back to ICS
3: Just do the normal system update that should just pop up.
My only fear is if the phone does not ask for update.

If you restore to stock using efrant's guide, it will be ICS since Google has not yet posted Jelly Bean firmware images. If you don't get the OTA notification or don't want to wait for it, you can just download and apply it manually (see here: http://forum.xda-developers.com/showthread.php?t=1419170)
