bluetooth on controllers stopped working

[spiderman1234]

I loaded up my ps3 and it said generic controller failed or unknown device now both ps3 real controllers wont sync bluetooth. I have them totually charge I put them in the micro usb to usb port and they play fine with usb cable in as soon as unplug them they blink red couple times and don't sync. This is for both controllers and they work fine on other ps3's. I tried resetting with a pin and that didn't work either. Any ideas I would thinking of making a system backup and factory reset but i only have one working usb port on this slim. Last time this issue just resolved itself. ' when i plug in controller on usb it works but says found unknown device.

im on firmware 4.88 cex Corbra 8.3

Try booting into safe mode and sync the controller there.
