"no signal bars" with a white "x" above network. Hello, Maybe this will help others who have this problem with their phones. I have searched online for this resolution, but had no success. I thought I would post this thread, seeing as how I ran into a problem with my HTC Desire HD, (running Android 2.3.5, and with a recent upgrade to HTC Sense 3.0). I have had this "perfectly working" phone for several months now. Recently, I performed a "System update" to "HTC Sense 3.0". From that point on, I have had connection issues with my phone after putting the device into "Airplane Mode", "rebooting" or even "powering on" the phone. I contacted Telus Support, and was led to this solution (quite quickly too) "If the phone does not connect to the network, go to menu > settings > wireless and networks > mobile networks > Network mode > select "WCDMA only". Mine was set as "GSM/WCDMA auto". The tech on the support line said that GSM was not used in North America. As soon as I highlighted "WCDMA only" my bars went to 4, and everything connected again immediately. I hope this will help, if you are having this problem. UPDATE!!!! 3 days later, and I am still having connection issues. I have had a "limited service" warning with the same "no signal bars, with a white x above" for the past 1 hour, then, all of a sudden, back to 4 bars, and eveything works again. Re-booting the phone, or even removing the battery has not made any difference that I can see. If I browse to menu > settings > wireless and networks > mobile networks > network operators > search networks,,,, I see three carriers. (my carrier Telus, Rogers, and Bell.) If I ry to connect to my carrier, I receive an error message that says " your SIM card does not allow a connection to this network", even though I am with Telus! Then, once the phone does connect (after a period of time), it now says connected to Telus, with a green star beside it!? I repeat, there were no issues before the automatic system update to HTC Sense 3.0 last week. Why does this have to happen now when this phone was working so well????!!!! When this happene again, I will try contacting Telus again for any more info. What would be great, is if someone out there knew of a fix? Thanks for reading UPDATE AGAIN. March 6th, all good for 1 week now. See thread below.
