as per the video in odin we dont select the option auto reboot while downgrading that's why we have to unplug the phone when the state "reset" in odin ...
i personally ask you to use this method which his mentioned in this link http://xdaforums.com/galaxy-grand-2/general/how-to-downgrade-to-nh6-t2913368 ...to downgrade your phone ...use jb firmware instead of nh6 mentioned in the point no 6. in the link
the firmware for downgrading should be Indonesia jb firmware & not Thailand as your phone is Indonesia....

thanks for the reply!

i still don't get your point, why use NH6? and i can't find any firmware with NH6

hey buddy you got my point wrong i asked you to use indonesia jelly bean firmware ng4 instead of nh6 which is mentioned in the point no.6 in the method to downgrade for which i gave you the link...

in the first page i update my post ,

If I downgrade by flashing Thailand Firmware and in future if i wish to upgrade to my own country's Kitkat Firmware then will it be possible?

yes you can if you have flashed this firmware
G7102XXUANG4_G7102OLBANG3_G7102DXUANG1_HOME.tar.md5 (JB 4.3)
than you can flash to
G7102XXUBNH6_G7102ODDBNH1_G7102DDUBNH1_HOME.tar.md5 (KK 4.4.2)

Hi,

Is it possible to downgrade G7102XXUBNK1 to JB 4.3 and if yes, could you post a link to the latest available JB, since I couldn't find anything below KK 4.4 on Sammobile?

Thanks in advance!

asheesh131 · Dec 30, 2014

Yes there is youtube link in this forum of the thiland jelly bean 4.3 search for it i have provided above the details of that firmware

asheesh131 · Dec 30, 2014

asheesh131 · Dec 31, 2014

NK1 is the 4.4.2 version which u mean is upgrading yes you can but if you are downgrading to 4.3 jelly bean version than you have to flash NG4 version hope you got my point

Thanks, I meant regarding CSC location - like some incompatibilities for Europe or missing translations in English (sorry for the noob question but I am not enough aware what could differ between these and don't want to risk something to go wrong

)

asheesh131 · Jan 8, 2015

No its compatible with the device the only difference is the some of the available languages and the carrier others are same

asheesh131 · Jan 8, 2015

See my work on NH6 built stock with note 4 weather, video player and s-health
