Hey, just putting it this out there. Had a problem with an Evo getting stuck in a boot loop. Not sure what the cause was. I did search the forums for a fix but everything I could find was referring to a rooted phone, and the problem with Exchange type e-mail did not apply in this instance. This phone was not being used with that type of e-mail account and the password was alphanumeric anyway. I did notice that the phone would reboot spontaneously on occasion early on, but I did not worry about it. I had read on the forums here that weird reboots are not all that uncommon. However, as time went by, the phone seemed to be getting more and more unstable. It has now reached the point that it will go through the boot cycle up to the 4G splash screen, then shut down and start over. I contacted Sprint, but being out of the 30 day trial period the only thing they were willing to do is file an insurance claim. So I talked to HTC and started the warranty repair process. The CSR I spoke with said it sounded like a chip had gone bad. Seems pretty painless so far but there is a bs "Triage and Technical Assesment" fee. Better than paying the $100 for the insurance though. Not looking for a fix. More just letting folks know. I would be interested to hear from any one that has gone through a warranty claim with HTC though. Still lovin' my Evo.
