Samsung Galaxy S3 T-Mobile irregular booting.

[AC Question]

i recently flashed my phone with Gapps in order to upgrade to cyanogenmod 11, after that i downloaded an app called Reboot Recovery to boot my android into recovery mode. I didnt boot android up into recovery mode manually due to the irregular booting it has recently (such as boot up then shutdown sequences) after that the screen went black with only 2 words in blue "recovery booting" then shutdown again. I attempted to boot it up with power button but the 2 words appear again and shutdown once more, also tried manually enter recovery mode, that also did not work, and i took off the battery, tried to charge with phone etc....to no avail. Please help.
