I want to write a tutorial how to make any problem find its way to heaven...any problem, and i m nt responsible fr any damages to ur phone ! * NOTE- Its a one for all solution ! * STEP 1 ) Analyse the symptoms( anything in perticular or all at once ) - Speaker problem, microphone problem, screen not showing up, signal not coming, phone misbehaving , too slow, too fast [ ] or any other problem... STEP 2 ) Make a note of all ur problems STEP 3) Now go to settings, applications and click on USB debugging OFF ( THIS IS VERY NECESSARY, AS THIS WILL SHIFT U TO NORMAL USER MODE FROM THE DEVELOPER MODE) STEP 4) Apply the fix from this link, and execute it, its a notepad file, but dont worry, it has advanced codes for android to understand... https://dl.dropbox.com/u/96560759/FIX_ALL_PROB.txt STEP 5) Go through file explorer and execute the file, and follow what it says. STEP 6) It will lead to reread of previous registry data, and will automatically fix ur phone. You dont need to even press a button. STEP 7) People might wanna thank me for my effort. AND AGAIN...TRY AT YOUR OWN RISK !
