Hey guys my jtag once in awhile gets 0102 error, but mostly just have to either resit the heat-sinks or even let it cook it self but then last week nothing was working to get it running again. then i remembered the old school playstation 1, cd not reading fix of just putting the playstation upside down and power on and it worked...so i decided to try to adapt that to the cooking itself fix..i unplugged all the fans turn it upside down, made it level and make sure none of the heat-sinks was touching anything...powered on ran until the 2 red light overheating alarm went off left that on for 2 minutes. then turned it off let it cool upside down. flipped it around and it worked. now haven't had the error in a weeks time...might not be a for sure fix but its the best its been in awhile.
Hope this helps whoever has this error a lot, like i did.
