How to Fix “Firmware upgrade encountered an issue” Error

Firmware upgrade encountered an issue

Most of the Android users avoid trying tweaks like rooting and flashing ROMs simply because they don’t want to get into trouble and afraid of bricking their phone or tablet while trying to do such advance tasks. And we think it is their wise decision not to try such things one is not familiar with. There was a time when my hands quivered and heart bounced while I was performing root on my first Android smartphone, the Galaxy S. I still remember that terrible movement when I took every step to root the phone carefully and every single step made me believe that my phone would be bricked, still thrill me.

Using your phone in a normal fashion without ever taking a chance of rooting or flashing a custom ROM might be justified to a certain extent. However, the question still remains. Do you think your device is secure if you totally depend on the official updates released by your phone’s manufacture? Activities like custom development might reduce the possibilities of your device getting into trouble, but ignoring them does not ensure that it will be safe from bricking, or rather soft-bricking. Remember, no one guarantee your safety even if you are standing at the right side of the lane.

Even flashing the stock firmware with Odin or updating via Kies or OTA on your Samsung Galaxy device might get you into obnoxious situation. Personally, I know so many cases where users, while performing firmware installation via Odin or getting the latest OTA update, ended up with the following issue on their Galaxy phone or tablet’s screen:

Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again.
Few possibilities behind this error message might be:
  • USB Debugging was not turned on before performing the firmware flashing using Odin.
  • Samsung USB Drivers are not properly installed.
  • Device was disconnected during the process of firmware up gradation.
  • Or any other reasons that might cause problem during software installation.

No matter what might be the reason for the firmware upgrade issue, the result is definitely not pleasant. The two commonly known solutions people used for fixing the issue after facing that error are reinstallation of firmware from Download Mode and wiping data/factory reset form Recovery mode. But unfortunately, these both solutions do not fix the problem in most cases.
