Fixing Odin Firmware Installation Failed at Hidden.img Issue on Samsung Galaxy Devices

14

Installing stock or official firmwares on Samsung devices is way easier that performing the same task on devices from other brands. You only have to get a utility called Odin, which has been developed by Samsung and is easily available unofficially, download the firmware file and go through a few steps to flash a firmware on any Galaxy phone or tablet.

Anyway, however simple such procedures may be, there always are the chances to get into some problem or mess. While most of the Odin flashes end up nicely with a PAAS! message, sometimes the firmware installation don’t end up as expected and fails because of some issue.

In the past, I wrote a bunch of tutorials for fixing different issues that are faced by users while trying to install a firmware on Samsung Galaxy device using Odin. Below, I’ve listed a few of them:
