Some of you may know already but if you don’t 3.10 OE-A has been released!! Changes include (from the README):

- Change from 3.03 firmware to 3.10
- 4th level of brightness (aka battery eater) can now be selected also without ac adaptor.
- Changes in hen core:

* Static user elf’s can now be executed in the 3.10 kernel. (this includes snes user version between other programs)

* Tyranid’s patch (added in 3.03 OE-C) consequences was not explained very well in the changelog of 3.03 OE-C:

- For programmers: it allows kernel modules to have user imports, making kernel programming in 3.03/3.10 less strict.
- For users: plugins and applications that worked in 2.71 SE, but not in OE, *may* now work in 3.03OE-C and 3.10 OE-A.

Sounds pretty good to me, I have just updated and it works like a charm. If you have modified your PSP make sure you back up your modified files before beginning or you will have to modify them again. Installation is the same as any other major Dark_Alex update but if you need some instructions read on.
Updating to 3.10 OE-A

1. Now to upgrade to 3.10 OE-A you will have to download this updater/update maker.
2. Once you have the 3.10 OE updater/update maker you will need to download the 1.5 EBOOT and the 3.10 EBOOT.
3. Now extract the 3.10 OE updater, the 1.5 EBOOT, and the 3.10 EBOOT.
4. Once you have that extracted inside the “310oe_a” folder you will find the following folders-

   310oeflasher
   310oeflasher%
   oeupdmaker
   oeupdmaker%
   Leeme
   Readme

   Copy the following folders to the PSP/GAME (or PSP/GAME150 if your at a 2.71 SE, 3.02 OE, or 3.03 OE firmware) folder-

   310oeflasher
   310oeflasher%
   oeupdmaker
   oeupdmaker%

5. Now rename the following EBOOTS to the following-

   1.5 EBOOT.pbp - 150.pbp

   3.10 EBOOT.pbp - 310.pbp

   Copy these to the oeupdmaker folder.

6. Go to your GAME section of your XMB and run the oeupdater NOT the 302oeflasher, wait until it’s done and then restart your PSP.
7. Once the oeupdater is completed copy the DATA.DXAR from the oeupdater folder to the 310oeflasher folder.
8. Make sure your PSP is charged over 75%, and then run the 310oeflasher NOT the oeupdater. Press X to accept the user agreement and wait until the flasher is finished, reboot your PSP.

You should now be at 3.10 OE, if not then your PSP shouldn’t boot at all, and will be considered bricked.

Guide will be updated soon!!
