So my dad got another phone to replace his since I couldn't get the MEID back. however I started on my quest to find out more information about the partitions.
as for his new phone, it has yet and even smaller flash size than the other 3 and this time I could tell where the size was taken out of, the userdata partition.
I also updated the prl to a new version so I could tell when I hit that partition by copying over one by one the unknown partitions from my CM7 phone.
partitions 2 and 3 did nothing to the phone that I could tell, 4 is the extended partition holding more and partition 5 from what I can tell holds boot data as the boot splash changed when I changed it. partition 6 threw the phone into 3 boot loops after getting to the main lock screen but then let me use the phone.
partition 13, 14, 15, 16, 17 sent the phone into 5 boot loops till I reverted it back
when I copied partitions 6, 13, 14, 15, 16 and 17 to the phone it then was fully functional with my phones MEID and the old PRL so I am guessing that their is some check amongst the partitions to make sure they all match with the radio
