I would be very grateful for suggestions or any experts to fix this issue. I tried downloading Kies as it says but Kies doesn't recognise or is not compatible with the Tab apparently. This now brought me to my current dilemma of the message 'Firmware upgrade encountered an issue.'
I tried to search online how to solve this new issue and they said to hold the buttons as mentioned before.
The software didn't work and my Tab was stuck on that screen with a blue line half way loading. The Samsung Galaxy Note 10.1 is a 10.1-inch tablet computer designed, developed and marketed by Samsung Electronics.The tablet runs Android 4.0.3 (Android 4.1.2 in Europe) and serves as a platform for multimedia consumption including movies, music, and web browsing. This was all started as I had lost the passcode for my Tab and was trying to look for a solution online.I downloaded FoneLab and it told me go into Download mode(pressing power button,volume down and home button at the same time).When I did this after the warning message showed up asking whether to contine the Andriod robot logo came up,below saying 'Downloading.Do not turn off target'. The message 'Firmware upgrade encountered an issue.Please select recovery mode in Kies & try again'.
