TA-082: GPS290 Trouble!!Help Plz

Hi.I have downgraded my PSP from 2.71>1.5 using Dark-Alex's downgrader and then 3.03 OE-B.Its a TA-082 Motherboard.
Therefore I have done the USBHOSTFS-Fix with 043.bin file and it was recovered
I installed 0.46 Mapthis and firstly I was using 2.71prxs for both usbacc.prx&usbgps.prx from GREEN PROGGIE and when I ran the Test and Mapthis I won't pick up any satellites and GPS STATE was off.
So I tried 2.71 usbacc.prx and 3.03usbgps.prx and everything is same (not working) except GPS STATE is On. I've struggling with this for 10hours. If anyone have experienced this or know how to fix, please help (please explain in detail)~~~~Thank you.

go up to 3.03OE-C and try both the 3.03prx's. Also are you useing the PSP290 or a GPSlim/generic GPS. Are you pressing X to activate the gps unit.

Thank you for quick reply.
I have upgraded to 3.03OE-C and tried both 3.03 prxs and I get Loading USB Module...Error message.
I'm using GPS290.
I tried 2.71usbacc & 3.03usbgps and On Mapthis I press Square to go GPS On but it wont get any satellites.

Stupid fact maybe, but you have to have a clear view at the sky to find sattelites.

Try also 2.17 USB.prx and 3.03 GPS.prx
