2) get the Minimus AVR manual v1.4 from the official site at
www.minimususb.com
3) to install the drivers for Minimus AVR, follow all the steps from page 1 to 3.
4) after driver installation is successful, take out the minimus. then follow all steps on PAGE 7 of the manual.
5) after the minimus is ready go program (using the page7 steps) , then go back to manual and follow all the steps from PAGE 4 to Page 6.
Make sure that during this 5th step, you use the hex file from step 1 that i uploaded and linked above.
6) Success!
As long as you don't delete the old backup manager from your ps3, your ps3 jailbreak games wont be deleted from the ps3. so if you want to move to another manager, just let the old manager stay there and install the new manager. u can use both side to side. will save you from hassle of having to ftp all games again.
