DOWNGRADE PSP FIRMWARE???????

knman has something. i have 1.52 and i did everthing on the list with slight mod on update number. im afraid to run it though. im at the screen where updates are often kept. but what happens if my system crashes. i wish somebody smart would try this.

 

i just tried it but it didnt work. im still playin with the file but to no avail. this seems to be the key though. where did you get this from knman. if someone else can get this working make a tutorial with pictures and stuff to show exactly what parts to edit.

 

i had a thought on my problems. maybe you cna only downgrade one version at a time. so go from 1.52 to 1.51 and so on.

 

There are currently 2 ways to downgrade. You can try to hardware and possiblly make your PSP a brick (way too involved) or you can run code. If you can run code on a 1.51 or up, then there is no need to downgrade because you can already run code.

So right now the answer is NO. If something becomes available you'll know. Trust me!

 

Does Anyone know if i can be able to downgrade the psp giga pack to firmware 1.5!? Thnx in advance

 

depends on what firmware it is, most likely its 2.5 which means NO you cannot downgrade it

if its 2.0 u CAN

hello people i have got a sony psp with the newest firmware unfortunately i didn't know about the homebrew security installment of the firmware and me being a big fan of homebrew games didn't even catch the anti homebrew feature so if anyone out there knows a way on how to downgrade psp firmware 2.53 back to the 1.00's please send me information to my email at DesertEagleCaliber88@yahoo.com thanks again peace out!!!!!!!!!!!!!!!!!!!!!!!

 

i apologize i mean i have psp firmware 2.50 not 2.53 there isn't even a 2.53 yet so if anyone knows any information on how to downgrade psp firmware 2.50 please send me any info on that to my email at
DesertEagleCaliber88@yahoo.com thanks peace out!!!!!!!!!!!!!!!!!!!

 

oh yeah just a reminder people don't upgrade if you currently have 2.0 or lower versions of firmware such a 1.50 or lower unless you wanna play new psp game's instead of homebrew

 

ok, this is driving me crazy, do you guys like rufuse to read the topic before you post. as you would see, we have said anything over version 2.00 cant be downgraded. come on cam1988, pay attention.

 

I agree. Information that has already been discussed here is being brought back up do to people not reading the previous post.

 

wait just a second there is a downgrade for psp firmware 2.0 if you look on google it shows you how to every where especially here at this website www.hackaday.com but thats not my problem my problem is trying to figure out a way to downgrade psp firmware 2.50 back to 2.0 or lower so if you have any knowledge on how to do that let me ne peace out!!!!!!!!!!!!!!!!!!!!!!!!

 

have you been living in a cave for the past 2-3 months? yes, thers a downgrader. and theres someone who believes they made an overflow.tiff for 2.5 psp's. but it only freezesa the psp, you can get it at pspupdates. or pspcrack.net

 

yeah i heard about that over flow tiff but its stupid unless you want to make your psp useless what its said to do is that it erases important psp system files which then makes your psp useless so i wouldn't try that psp 2.5 over flow tiff unless you wanna risk your psp for good so with that said peace out!!!!!!!!!!!

the easiest way to downgrade is to find a friend who has v. 1.5 or lower and copy the firmware files to your psp directory. you can also watch psp hacking 101 episode 5 (video.google.com) roflmao

 

no the easiest way to downgrade is to get the 1.5 downgrade at psp-hacks.com or good psp site.
