Hacking How To Softmod (Hack) Your PSP

[Rydian]

Oh shit, I thought it was updated to B8, now I realize I updated my own PSP while I was away from the temp. >>;

But yar, good idea.

I have a small question to ask: If I have a PSP Go with 6.35 on it, with 05g motherboard and never been on firmware 6.20, can I downgrade it ?

If the PSP itself has never been on 6.20 or less, then no.

However all Gos with 05g should have come with less than 6.20 (5.70 specifically), so ask whoever you got it from to make sure.

 

[Terminator02]

if it's a go it has to of been on 5.70, all of the commercially available GOs were shipped with it

so you are good for downgrading to 6.20

 

[ppkhoa]

Assume that mine can be downgraded to 6.20, the current firmware is 6.35, do I need to update to 6.39 and then downgrade to 6.20 or just downgrade straight to 6.20 without updating to 6.39

 

[prowler]

You don't need to update to 6.39 but you can if you feel like it.

I bought a PSP 3001 with 6.31 on craigslist and I don't know whether 6.20 was on it or not. Is there a way to check to see if I can downgrade to 6.20?

My advice: just skip PSPident and update to 6.39 (you're gonna have to upgrade the OFW to get cfw anyway), install PRO 6.39, and check System Information for your module number.

less than 7g means you can downgrade to 6.20
if not, just stay there and be happy, you're not really missing anything important .

 

[Akuma147]

Does that mean I can downgrade to 6.20 even if I upgrade to 6.39, as long as I have less than 7g?

yes, you will be able to use the 6.39 downgrader if less than 7g module.

Ok, cool. Thanks a lot for the help!

Great tut, Rydian. I just successfully downgraded my new/used PSP 3000 from 6.37 to 6.20 and installed the permanent CFW.

I even managed to pick up a PhotoFast CR-5400 msd to ProDuo adapter and got a class2 SanDisk 32GB msd working on my PSP. I saw some 16GB class4's go on sale recently at RadioShack for $25 a pop and was wondering if two class4 16GB msds would be better/worst/same as the aforementioned. Adv/?

run .iso files instead of .cso files and you will be fine.

Hi, I've run into some problems.
I successfully hacked 3 PSPs so far.
One was an old 1000, and two brand new 3000s.
Today I was trying to hack my nephew PSP 2000.
I checked the firmware on it , and it was 6.38. Naturally I run the downgrader, and I found out that it had a 2g board, wich should be fully hackable.
I successfully put an official 6.20 firmware on it , and preceded to install 6.20 PRO B8.
I put all the files in the right folders ( \psp\games\) and the permanent patch, but when I try to run the updater, it gets stucked on a black screen.
I tried a couple of times, always afraid of a brick, and then I checked the files on the card.
I found out that the PSP was previously hacked ( with an old Prometheus firmware or something ) but then it was accidentally updated to 6.38 trough an UMD update.
Re-reading the guide, I found out that in order to properly install official 6.20, older CFW was supposed to be removed, but I entirely skipped this step because the FW was already 6.38.
Now I'm on 6.20, but the 6.20B 8 updater simply doesn't work, I get a black screen everytime.
I even updated to 6.39, and then downgraded to 6.20 and retried, but still no luck.
Does anybody know what else can I do ? I suspect the updater doesn't work because 6.20 is not properly installed, but I'm not too sure what can I do at this point.
I would appreciate any help.

Have you disabled all plugins and reset vsh? (some people even recommend removing the entire seplugins folder)

Sometimes they can interfere with cfw and cause black screening.

Plugins don't work on a PSP with no CFW.
I suggest you try to Format Settings from the System Settings menu first, then run the 6.20 pro-b8 update.

Well that DID it, after resetting the System Settings I was able to successfully flash the 6.20 proB8 update.
Everything works fine so far.
Thanks a lot !

Thanks Rydian! Worked perfectly on my 2k1. Downgraded from 6.39 and applied the perm mod without a hitch. Great work for an easy to follow guide!

 

[Rydian]

D'aww, thanks.
