2.80 to 2.71 downgrader for TA-79 and TA-086
But just like the last downgrader by 0okm, don't expect it to be as easy as a downgrader by Dark_AleX. He seems to be not releasing the downgrader in public: You have to mail him and ask for it. While it would take me two minutes to mail him and obtain the downgrader and post it here, I will respect his decision of not releasing this in public. To ready yourself for the downgrade, here's a list of things you need: * The la-*test*-('") PSARDumper. * Firmware 2.71 Update Eboot. * PBP Unpacker. * The actual downdater. (Available on request) Once you have all these things ready, you'll need to find a friend who has a PSP (with firmware 1.5/2.71 HEN-D/2.71 SE/3.02 OE), which can run PSARDumper and extract the DATA.PSAR file. Here are the steps you need to take: 1. Open Firmware 2.71 Eboot in PBP Unpacker. 2. Extract the DATA.PSAR file somewhere on your PC and move it to the root of your Memory Stick. (On helper PSP with 1.5/2.71/2.71SE/3.02OE firmware) 3. Extract and run the la-*test*-('") PSARDumper on the helper PSP. 4. Press Circle when in PSARDumper to dump encrypted without sigcheck and dump reboot.bin. 5. Once the DATA.PSAR file has been dumped, move the newly created folder to the PSP which you want to downgrade. 6. Obtain the Downdater from 0okm and use the noobz team's xLoader to run the Downdater.
