note 2 firmware upgrade
now browsing by tag
If you are not sure what is the version of firmware that you are currently running, open the dial pad and ‘*#1234#’. A screen should pop-up and show you the AP, CP and CSC model. If you AP does not read N7105XXDMB3, then you are due for an upgrade.
Based on some testings perform by forumers in xda-developers, this version has fixed the battery drain issue found in N7105XXDLL7. And of course, it fixes some other minor bugs as well. For those who do not root your Note 2, you are good to go with Over-the-Air (OTA) update. Otherwise, you may download the firmwares below depending on your providers.
