phone keeps turning off and sometimes wont even turn back on!! HELP!

[jhemzC]

so i bought a used blackberry pearl 8100 the other day, and was aware it had a little issue reseting (the giy said it only reset about once a day, then even told me it hasnt done it in a while) but i figured it wouldnt be too horrible of an issue, and if it got a little worse i could just reset the phone.. but ever since the moment i got it, it wont stay on for more than a minute! and its gotten worse! ive tried doing the pull battery/hard reset nearly 30 times, then i tried doing a master reset, didnt work either, so then i did a Jl_cmder wipe and reinstalles my os, still didnt work, so i tried downgrading my os and it STILL didnt work!
ive read and done the "nuked" blackberry, as well as the "dead" blackberry.. im going insane as i feel ive tried everything ! i dont want to pay for it to be fixed until i know thats the only choice i have, and even so i dont have that sort of money right now.. please help.. ANYONE!

Wow. Seek the BigBadWulf. I'm sure he can help you on this matter, or at least enlighten you as regards to the status of your Pearl.
