hi, i got a Samsung indulge from metro and last week it was acting funny and not getting a solid signal. so i put it into air plane mode then i pulled the battery and put it back in to reset it. now the phone just boots itself turns on for 15sec and then reboots itself again. it keeps on doing this until the battery dies. now i have checked on the web, and it read about holding down the volume button and then turning it on to access the recovery menu. but nothing happens when i do that. i also heard of a usb jig to manually put the phone into DL mode. but i dont know if it would work for all galaxy phones. and what do i do after its in DL mode? do i have to re-flash it? and were/how would i do that? thanks
