Default [Q] software update and imei loss

hey all i have a ROOTED note 2 GT-n7100 bought with android 4.3 when i downgraded it to 4.1.1 i lost the imei, took a week to fix it anw now i have 4.1.1 on it and its annoying i wanna go back to 4.3.

okay so if i back up the efs/imei and unrooting it and updated it to 4.3, in case of losing the imei again can i just restore the efs file and everything will be normal ? or it donsent work that way ?

(gonna update it via odin cant thru ota cause my phone is modified)

when you are upgrading your phone via Odin as normal you will not loose efs

You'll not get any problem if you flash a proper rom on your device for upgrading, but backing up the efs is always advised.

Flash your proper official rom (Download it from Sammobile.com or Sampro.pl), After flashing, go directly to Recovery menu (By pressing Vol up + Menu and then Power key) and hit >>"Wipe data and cache"<< it'd get your IMEI back.
