Downgrade from 4.01m33 to 3.90m33 without pandora?

Hello All,
I would like to learn how to diwngrade from 4.01m33 to 3.90 m33 without panndora. I simply like 3.90 better. So is there any way to do this without pandora?

cheers

ok, the only way,to my knowledge, is to set up the normal Update folder like you were gonna update to 3.90m33 normally. now rename the UPDATE folder to RECOVERY and then in recovery menu, press "RUN PROGRAM AT PSP/GAME/RECOVERY/EBOOT.PBP and you should be sorted

 

Can anyone confirm this method actually works?
Don't want to run the risk of messing up my psp here...

 

Hello.

You need to search for a utility called Hellcat's Recovery Flasher. This utility does not require a Pandora Battery as long as you already have CFW. You just copy RECOVERY folder to your GAME folder, run it, and it reflashes your PSP to version 3.71 M33. It does not matter what version you had before. From there you can upgrade to whatever version you want. I've done it on my PSP slim, from version 4.01 M33 back to 3.71 M33 and then upgraded to 3.90 M33-3. Works like a charm. Good luck!

 

Here was I guide I made ... but seems it dosen't work with 4.01 M33, might as well try

 

thank you so much dejjen your guide works I really can trust you hahaha... anyway thanks...

 

the EBoot.psp process can not be done because that only works for upgrades, your looking to downgrade it. My suggestion is to buy a bag full of used psp games and sharpen the edges to the point they can be used as deadly flying diskette. You then proceed to get on a airplane and fly to France. While in France you hunt down the pspgen group and kill each and every one of them with a a sharpen umd to their forehead. After that, you will gain access to their gripshift hack save. You then copy it on a disc and send it to, guyod 3300 damnyoupspgen court, Gotohell, CA 98453. After that,you open their psp gen code and open the traitorous dark alex code and insert his code to install despertar cementerio v5 aka 3.90. place that save into your psp/game/savedata folder of your non-magic stick pro duo and start your psp with gripshift and load the file. Your welcome fireball2

 

I like guyod's idea, but seriously though...get a pandora battery and mms
