I bought a PSP with the version 2.71
but now i want to know is it ok to instantly downgrade it to 1.5 or will it brick because i never
upgraded it???

Upgrade it to 2.80. Then use a 2.80 dowgrader . Check first if your PSP is a TA-082 before , because use a non-TA-82 dowgrader in a Ta-82 one will brick it !
An new exploit found in Lumines allows run unsigned code in any fw version now... so if you have a Lumines UMD you can just wait for a "generic" dowgrader.

And of course... NEVER update your firmware to versions higher than 3.50. Sony will fix this exploit in the next fw version.

Ohhw ok but it will brick if i try to downgrade it to 1.5??Srry one more question is it possible to upgrade mine 2.71 to 2.71 SE-A ,B, or C???

To upgrade to any OE edition (2.71,3.02,3.03,3.10,3.30,3.40) you must have firmware 1.50 first.
Ah. You can dowgrade directly from 2.71 to 1.50.
Look int the Dark_ALex´s site and follow EXACTLY the instructions... the risk of brick is low.

I can´t help so much with the downgrade steps because i bough a used 3.40-OE...

Well the problem is that if you have
never upgraded your PSP it might
brick?? Well that is what i heard

Ohhw forgot to tell ya i bought it with the version 2.71

those are lies,

just downgrade from 2.71
make sure to read the readme for everything it should help you.
once you get to 1.50 go ahead and update to 3.03 OE-C or to 3.40 OE

So it doesn't matter if i never upgraded or
downgraded my PSP???Well i heard that you need to atleast upgrade once with you PSP to perform the downgrade scene (in my case to 1.5) or else it would brick??
