PLEASE HELP -- PSP IC1003 fw 3.03 - can i custom???

[jimbo77]

Hi all... yeah, fresh meat here. reading up on custom firmwares... had it figured out, but big ol problem now.

I was going to buy a PSP with official 3.03 fw on it. downgrade to 1.50 with GTA LC then up to 3.90 m33 -- so i can play iso/cso (even newer ones)... don't care about homebrew stuff.

Anyway.....

Just found out.... it's a IC1003 (that means TA-82 right?)

I DONT HAVE PANDORA BATTERY OR TOOL.

Some sites say it can be done, others say no.

Anyone.... is there a way without pandora/tool to get an official fw 3.03 TA-82 PSP to custom 3.90 m33 ???????

PLEASE HELP -- would love to get the deal (great deal while it lasts), but not if i cant play newest iso games.

(( i read you CAN downgrade to 1.50 HEN ??? the heck is hen, but then you have to use something called DEV-something..... and can't go to 3.90))

ANYONE ?

Thank you so much for any assist.

3.03 Downgrader Tutorial

Things Needed:

1. PSP running 3.03 Firmware (motherboard version doesnt matter)
2. UMD of Grand Theft Auto: Liberty City Stories w/ 2.00 Patch (2.60 patch doesnt work)
3. 3.03 Home Brew Enabler (download at bottom of tutorial)
4. NOOBZ Official 3.03-1.50 Downgrader

Notes Regarding GTA UMD's:

Unpatched versions of Liberty City Stories contain the 2.0 update, whereas patched versions contain higher updates. If your copy of LCS has an update higher than 2.0 on it, then you will have to find an unpatched UMD to proceed. There's no need to worry if you have a TA-082 PSP as the downgrader will check your motherboard and patch it if necessary. Note the downgrader will not let you proceed without patching if your motherboard requires it.

How To Use:

To use this simply download the 3.03 HEN files from the download links below and copy them to your PSP. Then run your unpatched version of GTA:LCS and the patch will apply itself. It will be stored in RAM and will stay there until you reset your PSP. Putting the PSP in sleep mode will not remove the patch.

One Disclaimer: Can you also note before use that it is possible to brick using this downgrader if you downgrade and then update to 3.03 and then downgrade again. The advice from Fanjita right now is to only use this once.

1. Update to firmware 3.03. If already have this firmware then proceed to step 2.

2. Open the 3.03 downgrade file and copy the contents of the folder MS_ROOT to the root of your memory stick.

3. Open the 1.5 update and rename the EBOOT.PBP to UPDATE.PBP then copy it to /PSP/GAME/UPDATE/
Make sure not to overwrite PSP/GAME/UPDATE/EBOOT.PBP

4. Load Grand Theft Auto: Liberty City Stories (unpatched)

5. It should get to loading save game, clear the screen, the screen should fill with a light blue color and then reset the PSP
(If this does not happen see below)

6. Check that HEN is running by going to system settings then System Information and it should show up as system version 303 HEN

7. If it is showing up as 3.03 HEN then go to the memory stick and run the x.yz update

8. Before the downgrader does anything to your PSP it will ask for you to agree to what it is doing
If you no longer want to continue press the Right Shoulder Button (R-TRIGGER).

9. Once you have agreed to start the downgrade do not unplug the PSP

10. Once finished the PSP will ask you to press X, after pressing it will reset it self.

11. If it comes up saying that the settings are corrupt press X to continue.

12. Enjoy your new shiny 1.5 PSP.
