THIS GUIDE IS NOT COMPLETELY FINISHED! MORE INFO COMING SOON!!

There has been some wrong info posted about what you need to do to downgrade, install DevHook, and installing CheatDevice. The plan for this thread is to get the right info out. If you find any problems or something wrong, feel free to report it to me. I want this thread to be 100% correct. There are some things where you will have to flash your PSP. This means writing info to the place where the PSP stores the firmware files, PSP config files, and more. This is the most risky thing you can do with your PSP but if you follow the standards, you should be fine. Here is some info you need to know.

Tips to make sure you don't get a brick
1. Make sure your battery is at least 50% (100% recommended)
2. Make sure your PSP AC adapter is plugged in.
3. Make sure you don't have a TA-082 mother board or higher. TA-082 mother board check
4. DO NOT TURN OFF YOUR PSP WHILE IT IS BEING FLASHED!!!!!
5. DO NOT REMOVE YOUR MEMORY STICK WHILE FLASHING YOUR PSP!!!!!

Some people are saying that you need to have an ISO to have CheatDevice. Not true at all! Thanks to LordSturm and Dark_Alex! LordSturm has created a CheatDevice flasher that flashes CheatDevice to the flash. This works with 2.71SE-B2 and it's firmware check process bypass.

[CheatDevice 2.1a is included in this package. To see if there has been any updates visit Edison Carter's site

When it comes time to upgrade CheatDevice, just place the updated PRX onto the root of your memory stick, load the program, and then hit circle. As easy as that! Also, this is fully uninstall able!

If you have anything you would like to see added to this thread, TELL ME!

why is there a billion of these

So n00bs like you dont flood our site with millions of topics.
I suggest all CS staff having this in their sig, as it will help the new ones alot.

Jesus Christ, you complain about everything...You probably dont even know half the stuff this guide is providing...

Nice tut, you put alot of effort into it..

I linked to you in my sig.

shut the fuck up you little bitch you always have to put your 2 cents in.....if you fucking have that much....
its probally you life savings!

atleast my useless post was pointing it out and WAS ONE TOPIC YOU LITTLE BITCH!

if your gunna fukcinh post just to insult some one Dont fucking post its that simple!



by the way i didn't mention this in my last post
nice tut but really there is alot.
but the more the marryer.

1. ummmm...you do know he is a mod right?

2. Correct me if I am wrong but I haven't seen one thread that sums EVERY THING up and has up to the date packages with all every thing you need already done and ready to run.

If all you are going to do is flame, just go away.

hes not a mod

the only mod in this topic (that posts) is \V/


and there is a cheat device .exe file at cheatdevice.com ummmm theres a bunch of devhook crap? is that what you meant

Ah sorry about the mod part. I thought you quoted \V/. Anyway, That installer that ADe made was for if you ran CheatDevice with an ISO, my CheatDevice thing I have in my thread is for the people with 2.71 SE-B and they don't want to use an ISO. Yes there is DevHook stuff, Downgrade stuff, etc. in the post. If you hate all my work sooooo much then just don't post.

BTW: Still waiting for the threads since you said there was billions of posts that where just like mine.

I'm just going to drop this because I'm in no mood to argue with someone with experience in idiocy...

In terms of Cheatsync Forums there are no other tutorials that discuss devhook, so there arent a million of these.

And that only mod is banning you for 2 days.

I hope you think about how you speak to people and how you should appreciate these great topic.

Good bye.

Right, I have followed the instructions and put Devhook onto my psp. When I try to start devhook, it says that the data is corrupt. HELP! Anyways, I tried the Cheat device install feature and instead of it saying Your psp doesnot have devhook, it says install. When I click it, it installs. Right, I think, lets play, BUT, It still says i need to upgrade to 2.81. PLEASE HELP ASAP!

WTF can't everyone just get along like good boys and girls!!!??? Arghhh...... <_<

You wish, if everyone got along, then we wouldn't need any mods or admins would we?

CAn some one HELP ME instead of talking family relations?!

No forum gets along perfectly..

Smeg, it seems your either running a messed up version of devhook, or you havnt got your dh firmwire folders there..

HELP. Situation...
I have 1.5.
I have devhook.46
The folders r there...but 2.71 is the highest. I cant see an SEB folder.
It can emulate 2.71max
How can I play vcs with cd
I dnt have a ta082 mother....
Dark alex's SEB are downloading as rar,How u get them onto ur psp.
People, i dont care how I can do it, just tell me how!
ASAP.....PLEEEEEASE!!!

Devhook 2.71 then play the iso of gta.
It will work.

Uh... No it's not... You don't have to flash anything to use DevHook...

DevHook installs some files to the flash like config files for the firmware.
