GUIDE: Time Machine - Load previous Firmwares through Pandora

This guide is meant for those having problems installing and using Time Machine or for those who are thinking about it, but are a bit confused. Hopefully this will help you.

Just in case you don't know what Time Machine does yet:
The TimeMachine is a program to load previous firmwares and custom firmwares from a memory stick using a pandora battery. Like devhook, but working through pandora and custom ipl's, it would work even if the flash and nand ipl of the machine is destroyed.

GUIDE:
1. Download and install Despertar del Cementario if you haven't already.

2. Download and copy the TIMEMACHINE folder to /PSP/GAME

3. Place the 3.60 psar (if needed)**, 1.50 eboot, and 3.40 eboot in the root named 360.PSAR, 150.pbp, 340.pbp respectively. (The 150.pbp and 340.pbp may already be on the root if you have D. Cementario installed).

4. From the XMB go to Game and run "Time Machine".

5. Install iplloader. This will install the timemachine iplloader in the memory stick.

6. Select the options to install the firmware(s) to the memory stick using the eboots/psar that were were placed there in step 3. (Note: 1.50+3.40HW & 3.60 M33 need the 360.psar on the root to be installed.)

7. To boot time machine shut down the PSP and start up with a Pandora's Battery.

•To boot 1.50 (phat only), Hold "X"
•To boot 1.50+3.40HW, Hold "O"
•To boot 3.40 OE (phat only), Hold "Triangle"
•To boot 3.60 M33 (slim only), Hold "Square"

*To boot the old ipl (D. Cementario menu), Hold "up" on the D-Pad and the Pandora menu will come up.
*To boot the orignal firmware on your PSP hold nothing. On a slim PSP you must have 3.90 M33-2 or up installed for this to work.

**There is no 3.60 update PBP since only slim PSPs came with it pre-installed. The only way to get the 3.60 data is to dump the firmware to a psar file using a slim PSP that has 3.60 M33 installed (I have included it in the download for ease).
