i did removed all my accounts from the tablet (and remove Samsung account !!). did a factory reset.
my device was purchased in korea, making it the SM-T865N version
factory unlocked
came stock with this:
checked by calling *#1234#
AP: T865NKOU2ASL3
CP: T865NKOU2ASL3
CSC: T865NKOO2ASL3

i downloaded this firmware file:

T865XXU2ASL3_T865OLM2ASL3_XSA.zip

from:

this is the United Kingdom firmware

i extracted it using 7zip.

put my tablet in download mode,

started ODIN, and loaded 4 files from the extracted firmware:

AP_T865XXU2ASL3_CL17437689_QB27772178_REV00_user_l ow_ship_MULTI_CERT_meta_OS9.tar.md5

CSC_OMC_OXM_T865OXM2ASL3_CL17437689_QB27772178_REV 00_user_low_ship_MULTI_CERT.tar.md5

i did not use:
HOME_CSC_OMC_OXM_T865OXM2ASL3_CL17437689_QB2777217 8_REV00_user_low_ship_MULTI_CERT.tar.md5
wanted to do a full wipe of all my settings and apps

i did not check any settings in ODIN.
Clicked Start, all went ok !!

its now an SM-T865
the weather app works, the downloads are faster, it has not dropped the wifi. cellular works as it should.
the only noticeable difference is with the phone app. there is no record the call button.
it also fixed the not connecting to the cell network unless it was in 3G only ... now works in lte/4G automatically


if i have any problems with it i will post again describing them. hopefully i never do
great news.. I wonder if this will work on my T835N as well.. the problem with LTE/4G connection really frustrating me... will try to flash it with other country's T835 firmware.. thanks for sharing..
