Downgrading a 2.80 PSP and upgrading to 3.40OE-A. Any Tips or warnings?

Yup. Downgrading my friends PSP from 2.80. I don't know if there is any important motherboard stuff I need to watch out for, or anything complicated.
Let me know if there are any tips I should know of before I start this!

Make sure you use a downgrader that will detect and patch a TA-082 motherboard just incase you have one and be sure to read the instructions 20 times if you need too to make yourself familiar with process and follow the instructions fully and you should be ok.
There are easier ways but you need gta-lcs unpatched or lumines to use them.
