[Jackrm9]

Can someone point me in the right direction I've been unlock for a few months now , but my touch pro went swimming last week ..... anyway after drying it out 4 a week to my surprise it still works. But the charging port no longer recognizes anything (headphones, computer usb, charger nothing so I've purchased a charger and spare battery 2 keep me going. Long story short i now have work out a deal to exchange the phone with sprint but i cant re lock the phone it just keeps saying loading.... Ive already reloaded a signed sprint ROM via the SD card but trying the re locker is becoming a hassle try re locker don't work redo sprint ROM try re locker don't work redo sprint ROM etc. etc. please any info would be greatly appreciated Oh yeah my soft reset button doesn't work either
