How to Fix Dreaded Green Light and No Boot
Hi. Not sure if this has been covered before (did search the forum and also google but couldn't see anything about it). If you end up with an S710 / Vox that exhibits the following problem:
Press Power button - Green light illuminates for approx 1 sec then extinguishes, no boot
But you can still access the tri-colour bootloader using Power & Camera button.
Simply open then close the SIM door. And voila! All working again! This has been driving me nuts - I bought four phones off ebay - replaced their broken screens and all exhibited the same problem - wouldn't turn on. It appears HTC have a switch on the SIM card door such that the phone will power off if the door is opened whilst the phone is on. In the process of dismantling the phone, sometimes this switch mechanism doesn't work properly, preventing the phone from turning on.... Wiggling the SIM cover after re-assembly fixes it.
Sorry if this is going over old ground, but thought it might be of help to some people.
