Which is the Best Custom Firmware at this time ?

[mike_jmg]

yes 3.52 was a great FW I think the cxmb plugin was released with that one, golden age of custom themes for me

I really like 3.71M33-4, both my psps have it , mainly because of the memory stick driver issues on the newer ones, well 3.90M33-3 wasn't that bad but it read the savegames of the games I was playing at that moment as corrupted, so I had to go back, I'll update when I wont need those

Probably 3.40 oe

For some reason i love that cfw

[alentris]

It might sound weird, but my favorite is 3.80 m33. It doesn't have many ctf themes, but it is stable, and it can use irshell.

3.71 M33-4 for sure

I'm still currently on 3.90 m33-3 lately I haven't had too much time untill now to install the current. I find that 3.90 m33-3 works fine and performs exactly how I need it to, but I will soon test the current and see what has changed in my view.

Definetly 4.01 M33-2 on a slim with time-machine because it allows full use of irShell with ahman's official btcnf patch, so you have all the benefits of 1.50 kernel, latest games (through latest kernel), savestates, and to top it all of a fully functional irshell

Hard to say.
Probably comes down to what you really need, want and whether or not you have a Slim or Phat PSP.

3.71M33 - The XMB is a little faster and CTF themes are easier albeit not quite as customizable as they are in 3.52M33.
The 3.71M FS driver is also much better for reading stubborn MS.
I don't know if the 3.71 FS driver works with 401.
Not really interested in testing it.

Otherwise there is little difference between 3.71 and 401 other than being able to load the current pops from flash.
I suppose POPS and UMD game requirements would be good reasons to upgrade.

I do know that I can still use the custom restart and shutdown prx's from 3.71M33 in 401.
The 351x199 01~12.BMP background trick from 3.71 still works in 401.
SplitMerge probably still works but I don't know about hex editing beyond 2 backgrounds.
Custom waves from 3.71 still work in 401 (system_plugin_bg.rco)

CXMB is a great plugin for all of those versions.

I've used 3.40 OE-A for quite some time, but I've been trying to update it for a few hours. 3.52 M33-4 is as far as I seem to be able to go. Whenever I try to install 3.71, 3.80 or 3.90 M33, it tells me my IDstorage is currupt, and that it needs to fix it before it can continue, then doesn't even install the CFW because my "System Configuration is not compatible" or some crap, then bricks because of the changed IDstorage...

*EDIT*
Got it to 3.90M33 thanks to Despertar del Cementerio v5. 3.90M33 seems to run a little better than 3.40 OE-A and 3.52 M33-4. The lack of the 1.50 kernel in the base code is a little on the annoying side though. I had all my Emulators and stuff set up and running perfect. I'll have to give the addon a shot and see how that goes.

Still like to know why I was getting that error though...

[eddy22]

i would say 2.71 SE-B'

no JK, probably 1.5 media center edition

no JK, i would say 4.01 M-33. I dont really use pops, so i dont care if other M-33 firmwares or OE firmwares have better pops. I just use the latest one. but i dont update to the latest until it has a 1.5 kernel addon

The way I understand it, it goes like this. Starting with firmware version 3.30 Sony's firmware installer checks to see if IDstorage key 5 is corrupt as that is needed for CFW to boot. These last few CFWs use Sony's official installer. So in short the Key 5 gets changed and your psp bricks, unless you fix key 5 before you shutdown the psp.
