Upgrading CFW (PSP-2000)

So, I haven't been keeping up with the PSP Scene for a while now and I know a lot of newer CFWs have been released already since 5.50 Prom-4. I was wondering what is the best CFW to use right now. I have a PSP-2000 with a 5.50 Prom-4 custom firmware.I would also need a guide for upgrading since it has been a while since I last did it.
Info and help is greatly appreciated.

actually all firmwares and all psp are hackablei think u should update to 6.60 either 6.60 pro or 6.60 me use google on these 2 cfw. I would say use 6.60 pro
its easy download 6.60 update
then download the 6.60 cfw from here:

I've Googled them and still am a bit confused. Can I just upgrade from 5.50 PROM-4 to 6.60 PRO (is this also the same as the PRO-B? Or is PRO-B a newer version?) or ME (Is the current ME version ME-1.3 or is there a newer one?)?Also, which is better: PRO or ME?Another thing, I haven't heard of this cipl flasher-thing. Why do I need it if I am just going to update from 5.50 PROM-4 to a newer CFW?Sorry for all the questions. XD

I would say pro since im using pro and yes pro b is the latest version if u want more information on cipl flasher, it is a thing that makes your cfw (6.60 pro B 10) permanent and also note this is ONLY FOR HACKABLE PSP.

I thought that CFWs for the phat and slim (non TA-088v3) are permanent. Or did they change that now?
Also, I read somewhere yesterday (can't remember where) that there is a dual boot CFW out? Is it a good idea to try that?On a note regarding PRO-B. Is B-9 the newest one?

No, PRO-B10 is the latest one. It's the one I'm currently using and so far, it's working awesomely.If you have any questions or need a tutorial on how to do it, just refer to this guidehttp://gbatemp.net/t293978-how-to-softmod-hack-your-pspAnd I also used this video.https://www.youtube.com/watch?v=uq5OGJKOKfkJust for clarification, you need the PSP to be in the OFFICIAL FIRMWARE in order for these methods to work.

Oh, so this one needs a lot more work than how we previously updated from one CFW to another...
I see...

yes u need to be on ofiicial fw for it to work, if u just update 5.50 to some other cfw it can cause a brick

Okay, one last question before I go ahead and try upgrading my CFW:Should I make a mistake, it would be possible for me to unbrick my psp since it is a 2000 with a TA-088v2 motherboard, correct? Just in case...EDIT:
This is also the instructions I plan to use (taken from a different forum):1. Open VSH menu by clicking on the Select button from xmb(main psp menu)
2. Change USB device to Flash0
3. Connect your psp to pc
4. Navigate to \vsh\etc\
5. Open version.txt using notepad or wordpad
6. In the first line change the 9.90 to 5.50 and save.
7. Disconnect your psp from the pc and change the USB device back to Memory stick in vsh menu
8. Download OFW 6.60 -[ u may search it thru google ]
9. Extract the file
10. Copy EBOOT.PBP to PSP/GAME/UPDATE/
11. From the xmb (main psp menu) run the update from Game – Memory Stick
12. Now you are on OFW 6.60
13. Download 6.60 PRO B10fix1 -[ u may search it thru google ]
14. Extract the file
15. Copy PROUPDATE and CIPL Flasher folders to PSP/GAME/
16. From the xmb (main psp menu) run the PROUPDATE from Game - Memory stick.
17. Press X to install CFW
18. From the xmb (main psp menu) run the CIPL Flasher from Game - Memory stick.
19. You have successfully installed 6.60 PRO B10

wait everthing u said was correct except you forgot about removing 5.50 cfw plz use the method that YOU posted about mine is useless

@Joel: How do I remove the cfw? I can't recall if it is through flashing (if I still needed to do that) or by simply upgrading to 6.60

updating the PSP's firmware will remove the cfw

Thanks. I'll start upgrading as soon as my battery reaches 80%.
Going to update to PRO-B9 first then to B10.

You don't really need to install PRO-B9 if you're going to install B10 afterwards. Just install B10 straight away.

lol, makes sense.
I thought the b10 was going to take a while to download but it didn't so I'm going straight to that instead. Saves me a lot of time. XD
Thanks.EDIT: Finished updating it. Not as hard as I thought it would be. XD I worried over nothing it seems as it went well. Just a question, though. I checked my system info and the mac address has changed to [model 2g] is that normal?

yes since mine is a go mine says model 05g its nothing really! it just hides you mac address and they r also working on pro C

SakuraMartinez · #15lol, makes sense.

That basically states what model your PSP is. I have a PSP 3000 [4g]. You don't need to worry about it. Only models 5g and above will experience problems. and only because those models can't downgrade their firmware.

UM sorry but lol where r u ?I can downgrade to other version * there is a new update on chronoswich downgrader that supports 6.60 and also model 05g

Replying to #18

Really? Huh, I must be late on the updates then...

Another question about this CFW (PRO-B10), does it have a built-in support for PSN or do I still need that plugin (forgot the name) to be able to download and use stuff from the PSN?
