Not 100% sure but looks like you flashed with reactivation lock on... Only way I know is to flash original stock rom but you may have flashed the new Kitkat bootloader.
You will need the Kitkat rom for your region to fix...

Mate, flash stock JB... Don't throw a new OS into the mix... It's easier if you use what you have 1st, fix it, then upgrade...

Ok bro i will try ...
Thanks for your help

Sounds like you tried to flash a KK rom with out flashing the KK bootloader.

Dear friend ... Seems your skilled about this tablet ... So maybe you can help me with my problem :
I were having problem with my nand memory so I managed to flash a ROM with having the " Wipe NAND all " ticked in Odin and after that I found that the phone wont boot so I thought it might be from the bootloader and updated the bootloader to KK and now I can't get my tablet to even boot android and also I can't mount /data ... is there any solution for me ? ... is there any way to get that JB firmware flashed on my tab ? ... is there any way to even boot the android to pick my files ? ... thanks in advance ...

Your problem is that you have flashed Xkat ROm without first flashing a stock 4.4.2 as clearly mentioned in the installation instructions of the ROM.
I think that now you have to try to flash A Stock 4.4.2 with Odin to get your tablet working again.

Well ...

Step1- Download Stock ROM from SAMMOBILE (for your device)
Step2- since you are in DN4... you would be having custom ROM -- clean your device by formating system/data/cache/etc etc
Step3- go to download mode (volume down+menu+power) and connect to your PC where ODIN is running...ensure you have Samsung USB driver installed on your PC
Step4- flash stock ROM downloaded in step 1
that is it....
Cheers

No It wont.... System, Data, Internal storage are the ones you should clean up when ever you change your ROM...
Samsung stopped at 4.4.2 for Note 2
DN4.2 is TOUCHWIZ at 4.4.4 (SG3 base ROM)
CM12.1 is AOSP, 5.1.1 r8

E980 Problem & Need Help

I have E980 that has secure boot error, and it boots into CWM 6.0.4.4 . However, it cant read / mount external , so i cant flash anything from microSD.
So, how do I upgrade to TWRP 2.8.7.0 and flash Slim LP ( is this latest and best ROM for this device ? ) TIA
PS : does sideloading the twrp recover work ?

There was a flashable zip of TWRP somewhere in TWRP thread, but generally, best way would be to simply flash it via flashify. You can always try to flash roms from internal SD or via sideload, but I'm not sure that old CWM will work with newer zips - it wasn't working well even back in Kitkat days, not now.
You can always flash Philz CWM, and use it as a starting point, and update to TWRP as soon as possible. Not that there is much going on for this device.

So , what is the best approach to fix it ? LG Flash stock KK kdz , re-root , flashify twrp , then flash LP ROM ? TIA
PS : once flashing LP ROM, do I have to deal with downgrade aboot/modem/etc. ?

Best approach would be to flash stock Jellybean, then root, install busybox, flash TWRP (can't remember if you have to flash one from FreeGee first and then update, last time I did a full reflash was long time ago), do a NAND backup and flash whatever you like after that, because half of our stuff is based on JB, even recoveries won't read KitKat partitions scheme well (kitkat has different modem partitions compared to jellybean so there is always a possibility you won't be able to backup and restore EFS, or you'll get a partial backup, because there are 3 EFS partitions).
Once you flash on Jellybean base, no further changes are necessary.

problems !!!

I got another problem while trying the LG flash tool stock ATT V20 tot file ( cant find kdz for E980 ) . I followed the guide , downloaded all necessary files, phone can be put into download mode . However, it wont show COM/Port in my laptop and show no device list in adb shell . It cant be driver problem becuz I tried to reinstall a few times and other phones can be detected fine in adb shell . Any idea ?
PS: Phone shows a yellow mark USB Composite device instead of LGE mobile com/port though .

You need LG's unified driver installed. Also, make sure that you have E980 (there are 5+ variants, all differences in firmware). Probably it would be best to download firmware according to IMEI.

Like i said i got proper driver installed and recognized by my other LG devices. I got it resolved now . The issue is with USB 3.0 . You have to use USB 2.0 for the LG Flash Tool and driver to work properly. This is also stated in the other threads . Thanks again

[GUIDE] [HOW-TO] Downgrade to 5.1.1 lolipop

So......first of all lets clear something out: nougat is fine. marshmallow is fine. even the first firmware that was ever released on the s6e+ was fine. But if for whatever reason you would want to downgrade to lolipop heres how:
WHAT YOU ARE ABOUT TO DIVE INTO INVOLVES HARDCORE BOOTLOADER MODS AND FLASHING SAMSUNG ENGINEERING FILES. PROCEED AT YOUR OWN RISK. NO ONE (INCLUDING ME) WILL BE RESPONSIBLE FOR ANY DAMAGE TO YOUR OWN PHONE.
So......downgrading to lolipop...... some ppl claimed it can be done by deleting some file in the odin .tar but that never worked for me.
If you have the sw rev check fail error upon downgrading....this is the guide for you
This will wipe all your data including internal storage (depending on how you do it)
Confirmed working on 2 g928f devices (one of em is mine) should* work on g928c but cant make any promises
disadvantages:
1. You cannot boot twrp while on the downgraded bootloader (still working on that tho)
2. You will only have system-wide root. DO NOT flash systemless or it will not boot (also rip safetynet)
3. Fingerprint is not working (still working on that)
4. You can only flash stock nougat or stock marshmallow from odin. You cannot flash lolipop tar,twrp tar,cf auto root tar or anything else
Instructions:
1. Wipe /data /system and /cache in twrp
2. Download this lolipop rom i cooked up in a few mins or any other lolipop rom (but this is tested as working w this method) and flash it (dont mind the supersu flash in the rom. it doesnt work. flash this supersu)
3. Download and flash this supersu (optional)(depends if u want root)
4. FLASH ALL OTHER MODS NOW BCUZ U CANT BOOT IN TWRP BACK LATER
you can try to boot but it wont. You need a bootloader
5. reboot in download mode and flash this modified bootloader
6. boot in stock recovery,wipe,cross fingers and hope it boots
If u ever wanna go back to nougat just flash stock .tar and no issues from there
Huuuuuge credits to @lucastanciu
The guy stayd a few hrs in a constant bootloader fkup to made this happen and has made a huuuuge contribution so that this guide could be possible and as safe as it is

HOW-TO:
Flash something (a mod for example) AFTER you flashed the rom and modded bootloader
flash this stock bootloader in bl tab
at the same time flash in ap the twrp tar.
boot into twrp flash whatever y need to flash
flash back from odin the modified bootloader

"I dont have a g928f or g928c
Can you mod a bootloader for me?"
Well.........depends....... if im bored yea i like to help ppl
Just give me ur model number and i will try to make one for you. No promises tho

U forgot to mention that this 5.1.1 lollipop is faster than any rom. With this rom i got the fastest boot time ever! I recommend u to try this rom ))

Deal with the g928g

Gracias very good onli necesari recovery

You deserve a ten, but please fix it to get into recovery and do not put tatas red letters that scare jaajajjaja good eunsaludo from spain

Ah yes. If you rooted then you have the deep sleep issue. This was an issue even with the original 5.1.1 it was fixed by flashing a custom kernel buuuut since we cant do that......... we just have to deal with it
