First of all yes 3.40 oe is worth installing so don't worry about installing 3.10oe just go to 3.40 oe from 1.5. I think you can do that. Someone correct me if I'm wrong. I do believe the instructions to update to 3.10 oe a is included in this tutorial. again correct me if I'm wrong.
You can get the 3.40 oe updater here: http://psp3d.com/homepage-news/13974...-released.html.
Oh and the difference between an oe a and an oe a' is that oe a is a first version and the oe a' is a second versions with some tweaks to it.
If anyone sees anything wrong with the information I just gave please inform me. I think i did alright though.

ok let me detail this for you a bit more so your aware of my issue

currently running 3.10 oea on my 2 psp's (one for my wife )

i didnt do the mod myself i paid some guy off of craigslist to do it
as i make a shit ton of money and he gauranteed no bricking
he used a proggy called easy downgrader to take it from
3.03 to 1.5 then back up to 3.10 OE a
now my cousin and brother and sister all want there psp's moddded (running custom firmware)
and i have decided i dont feel like paying $180 to have them all done and i figure i can do them myself
i just so happen to have
unpatched copy of LCS

so my questions
are this
(for my and my wifes psp's )
what does 3.40 OEA offer that i dont currently have
if it was decided that i should upgrade to 3.40 what is the process and does having a t82 mobo change the process

for my familys systems
does a t82 Mobo matter
How do i upgrade the firmware once im on 1.5


lastly
what is XMB i have heard you can retheme your psp using it
and the psp icons suck

i thank you very much for any information you provide


H20

3.40 oe a has some bug fixes and stuff. it's the same as the regular 3.40 except it can do Homebrew and play ripped games using Autopopstation. The process is what this tutorial tells you to do. You just use the eboot for 3.40 and the eboot for 1.5.
For your family's PSP to upgrade from 1.5 to a custom firmware you just download the oe installer and follow the instructions giving. see this tutorial for more info.
I don't think the t82 mobo will effect either of them but I think this tutorial covers that too.
As for customizing the XMB, you can customize them up to 3.10 oe I believe. search the forums for more info on that though.

Again i hope I was of some help.

hey,

I have an older PSP (PSP-1000) which was originally on firmware version 2.00.

Following your guide i have updated to 2.80, added the HEN and downgrader files onto my 32mb memorystick (definately all in the right place) but when i go to photos and the hen folder the PSP freezes for a second then shuts off, doesnt flash any color at all. Trying to run the cube sample afterwards doesnt work and throws up an error message!??!

How can i downgrade to 1.50???

Thanks

I think you mean to say TA-082/TA-086. All PSPs have TA-something motherboards.

You can find out how to check for it here.

very helpful guide! answered all my questions on downgrading and upgrading my firmware.
My question tho is, do I really need an unpatched LCS? does it have to be LCS? I do however have a different UMD with a v2.00 update on it. can I use this instead?

No, it has to be LCS and it has to be unpatched (ie 2.00 update) The update has nothing to do with downgrading, its just mentioned as a way to identify an unpatched copy of LCS. Its the actuall LCS game that contains the exploit which the downgrader depends apon to... downgrade lol.
