Hello
My tab has been disturbing me of recent with boot loop which forces me to factory format it and this happens about twice a month

I'm considering firmware upgrade but the on air update says there is no software update and the Samsung kies says my tab does not allow initialization
What is the way forward for this
Can you tell me the firmware I can use and links to the firmware to download
My tab details are
PDA: 3100XXALD4
CSC: P3100OJVALD4
ANDRIOD VERSION OF THE TAB IS 4.0.3

the tablet was made in Vietnam

Thanks
