[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.

Repairing Xperia J With PCC

Hi Friends,
I wanted to have my Xperia J with ICS 11.0.A.7.5 firmware to be backed up. So following some post here on this forum stating that first repair phone using PCC and then go to db\13740270\blob_fs and copy 3 files with name "File....." and then convert the file to ftf using Flashtool.
So I first repair it using PCC. It succesfully repaired but after repairing, I found that now it is not ICS 11.0.A.7.5 but its JB11.2.A.0.31.
Also instead of 3 files with name starting with "File..." in db\13740270\blob_fs folder, there are 4 files starting with that name.
Can someone please guide me out of these 4 files, which files are to be selected in Flashtool for creating .ftf file to keep the backup of 11.2.A.0.31 firmware?
Also we know that there are some bugs in JB 11.2.A.0.31 as well as its hard to root this version. So if I want to go back to ICS 11.0.A.7.5, how can i revert back.
Thanks very much.

Regarding the backup I'm not sure exactly but from what I understand you want to save the .31 firmware for future flashing. If so, if the .31 firmware is unbranded you won't need to save it because there are links to the .31 Central European version ftf file on these forums.
And regarding the getting back part, if you ever wanna go back to ICS you can just flash the ICS .ftf file ( again you can find the links in the threads here) and you're done. BTW, if you wanna update to .31 I would recommend rooting the ICS and then updating OTA so that you can keep your root.

Thanks Sir for your guidance.
I did it this way...
Previously it was ICS unbranded and I rooted it sucessfully. Then I Repaired it with PCC (for getting backup of ICS) but it was repaired with JB .31 and root was lost.
Should I follow this way ?
First Flash ICS 7.5 .ftf file, then root it, then OTA update with JB. I also want to know that :
1. Will instead OTA updating with PCC work?
2.Is there any way to get back ICS by flashing with PCC instead of flash tools?
Thanks

Not a problem man.
To answer your questions :
1- If you update withe Pc companion you will loose your root. Only updating over the air will keep the root. ( after you finish the updating process you simply need to update the superuser app from the playstore).
2- Unfortunately, if you use the repair function Pc Companion will give you the latest version available, there is no way of choosing which Android Version to install, it will choose it for you. So if you want ICS you need to flash the .ftf file with flashtools

[Problem] xperia J

My boot loader is blocked so i can't enable it, but is there any way i can flash my firmware with a new ROM?
For example when my mobile phone search for updates i could redirect that request so i could simulate an update with a new rom, so my phone would download it and install it, is that possible?
Or is there any way?
(The mobile phone it's already rooted)
Thanks

anyone?

You can flash stock rom firmware on locked bootloadet too! All you need is flashtool + search button

You could install a "stock" based rom with an unlocked bootloader. There is NO way to install a more recent version of android without bootloader access or an official update.
An example of a stock based rom is GIMLO for Xperia Tipo and Miro (and a few others I believe), runs the base firmware but is fully skinned and much faster than the stock ROM.

[Q] I need to relock bootloader and unroot to flash the stock rom?

1- Do I need to unroot the phone(xperia L) and relock the bootloader to flash the stock rom?
2-Does flashing the stock rom removes CWM(I want to remove it)?
Thank's in advance!

you can return to stock firmware using FLASH TOOL for xperia ( google it )
With this you can lock the bootloader but before that flash the stock rom @ http://forum.xda-developers.com/xperia-l/general/sony-xperia-l-flashable-ftfs-locked-t2560642
and yes flashing stock rom with FLASH TOOL will also remove CWM
hit thanks if that helped because today i also returned to stock rom

Xperia l update
Hello guys. I'm new to this forum and i have one simple question.
I have an Xperia L c2105 rooted and with unlocked bootloader. Today when I connected it to my pc i received a notification from PC Companion with an update. I couldn't update it because the program said that I have a modified software or something like that.
Can I update my phone without losing root and with the bootloader unlocked? If i flash the stock rom update do i lose root and my bootloader will be locked?
PS: Sorry for my english, i hope you can help me deal with this...:good:

C'mon guys no one can help me?

Firstly,updates via pc companion or SUS requires lock bootloader..if you have TA backup just restored it and it will be updated officially.
Second...Flashing new firmware will erased everything and your bootloader still will be unlocked if throu flashtool..
Third...when using flashtool, there are a few choices you can make like saving your data and etc but its recommended to wipe everything..
your data etc can be backup using 3rd party app..
The easiest way to root is using extended stock kernel v6 kernel..It has built in root and its binaries..

Thank you very much. I didn't save TA when I unlocked the bootloader so I assume that I can't get it locked. So in this case I will do the update trough flashtool. After flashing the update I will just restore root. Have a nice day

You need to flash the ftf.. AFAIK the update centre updates do not work after bootloader unlock or something..

Yes, this is true, after unlocking bootloader Sony Update Center complains about "modified software". You need the ftf (search on xda for xperia l ftf 15.3.a.1.17)
