I'm not sure if this goes here, but I've noticed this happens only with game UMDs bought from the store.

This only works if you have access to the recovery menu.

80020148 means "Unsupported PRX type", coming up when either A)When you are running an iso with a fake mem. stick (Which I've yet to test out so I can cover a little more ground with this error), or B) Because Sony doesn't know how to do things right anymore (No, not really, but there is another reason out there that I'm still unsure about), but, if you're running on an OE homebrew, I've found a way to fix it. This should NOT brick the PSP, but, if it happens to do so, though I'm 95% sure it won't, I am NOT responsible for what happened. Just covering myself up if it were to take place.

1) Remove the battery from your PSP for a few minutes.
2) Put the battery back in and access the recovery menu. (Press and hold R and THEN turn the power on)
3) Under the "Configuration" tab, enable everything EXCEPT "Fake region". (Disable "Fake region" if it is on)
4) Under the "Advanced" tab, go under "Advanced Configuration", then enable everything except "Execute BOOT.BIN in UMD/ISO". (Disable "Execute BOOT.BIN..." if it is on.)

Everything else should be set to default, like it would when you first installed an OE firmware. DO NOT mess with anything else unless you are experienced with doing so.

Hopefully, this'll help anyone who gets this error.

EDIT II:

I've come to find that some of the homebrew apps/games get this error. From what I've tried, repeatedly, what I've stated above CAN NOT make the games or applications run. I've no clue why, plus its a bit over my head at the moment, but hopefully in the future I can find a way to fix it, or force-run the eboot.

80020148 - Unsupported PRX type | This error also seems to appear when you are running an iso with a fake mem. stick

O.o Well, thats new. I thought it was basically a "Sony hates you, we won't run this game for you because you're on homebrew" error. Thanks for the info though!

Hi!
I'm from Bosnia and my English is not so good...so don't mind me.
Fleet,I listened your advices of this resolving the problem but in recovery mode when I go to configuration tab,display is all blue and there's no any text or something.after a few moments PSP turns off...answer to me,pleeeaasssssseeeeeeeeeeee

Well you speak better English then some of our native English speaking members here so don't worry. What firmware are you using? And please next time make your own topic, including information such as what firmware you are using.

Yea, i didn't see anything wrong with his writing. I wouldn't have noticed anything.

Thanks...I am using 3.40 OE-A firmware

Is there any newer OE-A firmware?If there is can you tell me the link of that?

nope, 3.40 OE-A is the latest OE. then it moves on to the M33's. like 3.52 M33.
