    READ THE RED WRITING OR BRICK YOUR PSP



    Need to downgrade and haven't a clue how to, well you came to the right place. Everything you need is in the download.

    If you have a TA-082 Model (Check Here) It can now be Downgraded make sure to download the right package 2.80->1.5.

    Also them "Easy Downgraders" are OLD and UNSAFE, use the ones i have linked, they are the most up to date and your best option, any problems just post and i will try my best to help you.


    The 2.71 Downgrader's Uses Dark_Alex's new Update Flasher for 2.71. Which is Extremely Safe. Also these downgrader's use official sony updates, so no need to do a clean install afterwards.

    Upgrading to 2.71 and then downgrading from there to version 1.5, is the safest way of downgrading.

    All downloads are with Installer's and Instruction's.
    And i have personally tested each one myself for safety.

    as if will harm your psp, it is ok for you to upgrade to 3.03oe.

    What To Do After DownGrading

    3.10oe-A Open Edition Firmware Installer
    If you have a 1.5, you can use this, Its 3.10 mixed with 1.5 so you can play your PSX games without the need for a PS3 and all the other features 3.10 has, It other best strength it it can launch homebrew just like a 1.5 and also launch ISO's straight from the GAME menu.

    Devhook for 2.71(esp. TA-082)
    If you have a TA-082 Model PSP or v2.71 and if you are afraid of downgrading, you can still use devhook and use ISo's aswell and not miss out on anything a 1.5 has. (To Do So Check Here)

    Devhook .51.1 Installer
    When you have downgraded to 1.5, you will need Devhook to play your Umd's and ISO's(but i advise on getting 3.03oe).
    Here's a Link, to Devhook .51.1 Installer

    Devhook for 1.5 Maxed out
    When you have downgraded to 1.5, you will need Devhook to play your Umd's and ISO's.
    Here's a Link, to my personal Devhook.46.
