Your device is now stuck inside a 'Boot Loop'....You should be able to fix this by entering recovery mode and reseting your device. To enter recovery mode you should - First make sure to power off your device. > Then by pressing and holding Volume Up, Volume Down and Power Button all at the same time your device should enter recovery mode (Note that you should release all buttons when the Blu Studio 7.0 screen flickers) > Then navigate to the reset/format option (WARNING : YOU WILL LOSE WHATEVER YOU PREVIOUSLY SAVED ON THIS DEVICE..PLEASE REMOVE YOUR SD CARD BEFORE PROCEEDING) > After this your device should boot normally (it would take some time for the first boot to happen).
Have you tried removing the battery for a minute or more? Try removing the battery and remove power supply also...Then hold down the power button without the power supply for 1 minute or more...when holding the power button down plug-in the power cable ...something should come up your screen...if YES then put the battery back ...if no then tell me.

The R4i card currently is blocked on the Nintendo 1.4.1 firmware, this is normal. Nintendo is doing a good job at preventing you from playing illegally downloaded copies of their games. Cards that work on the 1.4.1 firmware (genuine cards only, I don't know about clones / fakes, but they probably don't work) include the Acekard 2i, EZFlash Vi and M3i Zero I'd recommend buying your DS cards from dscardworld.com or nds-gear.com but probably nds-gear if you live in Canada or Europe since their international shipping's a bit cheaper you can try this offical site for the firmware kernel- http://www.r4i-sdhc.com/
