Master Reset TREO 755p

I killed two phones using a wired headset. The jack in the phone gets stuck (crappy connector) and the phone still thinks the headset is plugged in even when removed.

I have had this same problem from day one with my 755p. The issue is that the phone still thinks there is a headset plugged into it-even though there isn't one. I have heard it is because of poor welding. If you have the monthly protection plan you should be able to take it into a Sprint store and have them give you a new phone (I have done this twice now). For the meantime, you can stick a paperclip into the headset hole and toggle the switch. This is only a temporary fix. I have not heard of Sprint/Palm actually fixing the problem-it is probably cheaper for them just to give out new phones. I hope this helps...

I was talking to my wife using a headset on my way home when it disconnected suddenly & refused to establish contact again. Although it said I was connected, I couldn't hear anything. Been this way about five days till now. I was Just reading all of these Solutions, looked at my phone, & had the very savage & primitive idea of just blowing into the headset jack... hard. Well, I just dialed my voicemail. everything is working fine now, & looks like I'll be able to catch up, on all those calls i since last Saturday. Its not the most direct way of ACTUALLY fixing complicated electronic devices, but it sure was effective for me. worth a shot. :-/

Palm refuses to acknowledge that there is a problem despite the widespread posts on the internet about this specific issue!

I used an electrical contact cleaner that fixed my phone immediately, we will see for how long

I went through 4 Treo 650's, even sent one in to have some guy in California re-do the jacks. Worked for a while, then broke again. With the 755, I tried WD 40, and worked the jack in and out. Worked great for a while. Now I'm waiting for my replacement unit to show up. Jeezzz this gets old!!!

I have no great solutions other than what everyone and their brother will tell you which is to backup your information and do a hard reset. However, I've also experienced this now on my 3rd 755p in which the audio is no longer functioning on phone calls. I'll be calling Palm. I'll let you know if there's a better fix or what transpires.
