[Q] Unable to update Tab2 via OTA (Urgent)

First of Hello to all the XDA members . I'm new in here , also new in using android OS & hoping to get help from you guys .
I have a Samsung Galaxy tab2 P3100 , after lots of searching I'm unable to find any process to move game data to the External sd card without root , So I had to root my device only for that issue by Odin using the easiest process but never install any custom ROM . After that everything goes well with moving data.
Now Samsung is offering 4.1.2 update for tab 2 , but I'm unable to update my device officially for the root issue by OTA or Kies . Now my questions are
1. Is it possible to update via OTA without loosing root ? If yes , then how ?
2. If I unroot my device to update via OTA , is there any working other procedure to move data to external memory card ?
I'm attaching to images of the current version details of my device & the notification that I'm getting by trying to update it via OTA .

1. Is it possible to update via OTA without loosing root ? If yes , then how ?
NO
2. If I unroot my device to update via OTA , is there any working other procedure to move data to external memory card ?
NO
why dont you just download your latest firmware from sammobile.com then root it?

Yes you can update through Kies but u have to unroot ur tab.
Steps:
1. install Triangle away to reset counter to 0.
2. unroot completely through SuperSu.
3. Then wipe data/factory reset ur tab.
4. Now Connect to Kies and update ur tab.
Alternate method
u can flash stock rom through odin and official stock rom can be downloaded from this link:
http://www.hotfile.com/dl/200000232/429d471/P3100DDCMC1_P3100ODDCMC1_INU.zip.html
enjoy............

Thanks to both of you for your helps ,
yesterday I have installed triangle away to set the counter to 0 ,
then completed unrooting with SuperSU ,
After that downloaded the Stock rom from Sam mobile & then flashed my tab with it .
But after flashing the device with it the status still shows "Custom" & the update device option "Keep on checking for software update & never ends"
I have also checked with root checker & it says my device is not rooted .
So , please help me to bring my device official status back & make the update device option working .

Can u tell me which Rom/firmware u had flashed.
flash with the latest Rom/firmware from sammobile by Odin.

Its useless checking for updates if you have flashed the latest firmware already! Root it and have fun.

But at least it should show "There is no update for your device or your device has the latest firmware already" . Because I'm thinking about the future official updates & also the device status "modified" .

flash ur Rom again with mobile odin pro with ever root optn. see it works? also set ur counter to zero.

I guess EverRoot option in Mobile ODIN will root the firmware while you flash it & I will not lose root .
But I don't want root , I just want that my device status change from "custom" to "official" & also make the OTA works normally .

follow...........
so r u ready to unroot ur tab.
Follow this
Flash ur rom with older firmware using mobile odin pro with everroot and inject supersu checked.
check ur counter flash and it should be zero. uninstall triangle. unroot ur tab completely rom from supersu option. restart ur tab now press power and vol+ toghter.
Now wipe data.
restart now connect ur tab through kies and update it to latest firmware.
u r status is now official.

Can you find the last official firmware for your tab/region on sammmobile? The flash count shouldn't matter, but i have found that the custom part is what you need to worry about. Try using Odin for PC. Whenever i flash official firmware with it it reads as official firmware and allows ota.
Edit, I'm just thinking that it would be much easier for you to use a PC to just flash the firmware, and not worry about unrooting and all that.

Hello bro , I would like you to know that I always flash with Odin using my PC & I have downloaded the latest firmware for my tab 2 from Sam Mobile & flashed with it . But the device status is still "Custom" & the OTA keeps checking for updates but never finishes . Can you share the link of the tutorial how you flashed the Official firmware using Odin via PC ? though I guess it's same but wanna check that too.

Ill see if i can find it. I usually just use an old ICS firmware i found on here, and that brings me back to official status and can update from there.
OK found it. I wouldn't use the file, maybe just find a firmware that you know worked on your tab, an old ICS for instance.

You could get better help if you would have included your country and the firmware or build number that your current using.
With that said.... goto samfirmware and download the latest firmware for your device. Then use odin to flash the firmware, you should then have latest update and you can then root again.
There are other methodes but I think this is the least complicated.

my note details is added
I know your method and used it a lot via mobile odin, but I used to keep the
root from options, and iam not sure if the new firmware will wipe my note or not if I flash it via odin pc
I read that flashing the stock recovery will unroot it.

I read that flashing the stock recovery will unroot it.
Flashing stock rom removes root .
But latest updates are more likely on XDA or sammobile before Kies or OTA .

I see your updated info except for country that you live in. You may have the newest for your country.
Yes, flashing a new firmware with PC Odin will remove root,.
I have not done it in a while but from what I remember all data remains in tack, just don't do a factory reset.
I do believe that there is a way to install a factory firmware in mobile Odin and keep root but I have never done that method.

unrooting will open OTA update to update the device with 70-80 mb rather than downloading 1 gb

Nice. Let's hope this does help users like we thought it would..

do we have to be rooted to flash modem from odin? does it trip knox?
thanks

You don't need to be rooted. And I don't think knox will be tripped since you aren't flashing anything that's been modified, only flashing unsigned/modified images via Odin trips knox. But since you are flazing a signed modem you should be fine.

Hi,
Thanks for the guide. Very helpfull. I have a few Noob questions...
1. Do I have to do a full wipe/ cleam install after updating modem, or will the OS remain intact?
2. Where can I find the latest modem for N9005?
3. Is the latest modem always the best, or should I only update if I'm currently experiencing problems with the 'old' modem
Thanks...

1. No need. Just follow the guide, nothing more..
2. Check the modem thread that's in the general section, if you can't find it there then you may have to pull it from the stock FW. Also some roms devs have the modem in their OTA/OP so may wanna check there as well.
3. New isn't always better. Update if you have issues, if something isn't broken then there is no need to fix it.

with the current modem/firmware/bootloader (I don't know what gives me the issue) I cannot use LTE while I have an SM-N9005 and friend of mine with unrooted Note 3 (bought in a shop in our country) has LTE 4g, while I have an Italian CSC.
If I use a modem from an other rom, will I have LTE as well and still have my Knox intact?

Thanks a lot guys
Your threat was a live saver man. For a sec I thought I lost my phone. Flashed modems b 4 but thanks to u I got reminded to use the new Odin(stupid me used the old one).

You cannot go back to old bootloader once you are on KitKat, try flashing a new firmware.....

My phone currently is running the KOT49H.N9005DXUGNH1 rom, but i have a need to flash the N900XXUDNC1 modem. Can I do that?

Are you Flashing the Full Firmware to update the bootloader?
Are you Flashing the Correct Firmware for your Carrier and Device?
Your Device is in Download Mode?
USB Debugging is enabled?
You Have the Samsung Drivers installed on your pc?
If the answers to the above is Yes - Try a different USB cable and Port on your pc

Thanks for your answer . Do i have to flash a full firmware and the bootlader at the same time?, cause i just use the bootloader zip to flash.
