Recovery mode

Have a cheap BLUC5L. Using as backup 'til I get a new phone. Phone has a lot of glitches, strange occurrences and just weirdness going on. Would like to flash a ROM to it. However, I cannot get it to go into recovery. I've tried; power off, volume up/power...volume down/power...both volume up/down/power. No luck. Also, cannot get phone "recognized" by Win. 10, even though I've D/led the drivers. Need this phone until I can get a better one....soon! Got any ideas?
