'Firmware upgrade encountered an issue.Please select recovery mode in

Hello,

The message 'Firmware upgrade encountered an issue.Please select recovery mode in Kies & try again'.

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 software didn't work and my Tab was stuck on that screen with a blue line half way loading.

I tried to search online how to solve this new issue and they said to hold the buttons as mentioned before.

This now brought me to my current dilemma of the message 'Firmware upgrade encountered an issue...'

I tried downloading Kies as it says but Kies doesn't recognise or is not compatible with the Tab apparently.

I would be very grateful for suggestions or any experts to fix this issue.

Thank you.
