Default [Q] Galaxy tab 2 P3100 JB 4.1.2 (rooted using CF-Auto-Root) Official updates question

Hello,

I am from India and recently purchased Galaxy tab 2 P3100 model with Jelly Bean 4.1.2 version built in on it.

Baseband

P3100DDCLK1

Kernel Version
3.0.31-812001
se.infra@SEP-98#1
SMP PREEMPT Fri Mar 8 20:09:50 KST 2013

Build Number
JZO54K.P3100DDCMC1

I have tried to root the device two days back, here is what happened,

1) Copied cwm-root-gtab2.zip and Fix-Recovery.zip to external SD Card. Flashed GT-P3100_ClockworkMod-Recovery_6.0.1.0.tar using Odin successfully.
2) Went in to ClockWorkMod Recovery mode (power button + volume up) and Installed cwm-root-gtab2.zip and Fix-Recovery.zip using CWM Recovery successfully.
3) Rebooted the tab. ROOTING WAS NOT SUCCESSFUL.
4) Went in to download mode again and flashed CF-Auto-Root-espressorf-espressorfxx-gtp3100.zip using Odin and ROOTING WAS SUCCESS
5) But CWM Recovery was gone. So I went in to Download mode again and flashed GT-P3100_ClockworkMod-Recovery_6.0.1.0.tar to get CWM.

Now I have CWM and Rooting.

Question is will I be able to receive Samsung official updates whenever they are available?

U will not be able to update your tab over-the-air (from settings). Instead connect it to a laptop or pc and use samsung kies to update it. Make sure to unroot before you update using either of these methods or you might get a bootloop (stuck on boot screen).
Check out my thread if u want to root or unroot tab 2.

I went to Settings->About device->Software update->Update and I get below error message,

"Your device has been modified. Software updates are not available"

I opened SuperSu app and went to settings and did "Full Unroot" and rebooted the device. After rebooting verified in "Root Checker" app that root access is removed. Tried Software update again and still same error message.

What is the way to restore my Official Software update?

If I am correct, we should still get 4.2 by 2013 Q3 end. I don't want to miss that.
Btw, on top of unrooting, I also had to flash stock recovery to get rid of "Your device has been modified. Software updates are not available" error.
However now when I do, Settings->About device->Software update->Update I simply see a screen showing "Checking for software updates..." and that never completes. Could it be Samsung server error? or am I still being kicked out from Official updates? I remember that, earlier (before rooting) when I do this, I used to see some thing like "your device is already up to date".

Here is my observation. If you have ever rooted your tab 2 (using recovery or odin) in order to receive official updates you need to do the following,

* Use Triangle Away to reset the flash counter.
* Unroot the tab.
* If you have flashed CWM Recovery, re flash stock recovery.
* Finally flash stock firmware using odin (you can download your stock firmware from samemobile.com). When you flash stock firmware your flash count wont increase.
