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.

thankssssssssssssss

When reassembling the upper part of the device you must make sure that the SIM door actually fits to the switch correctly. Best is to have the door open when putting the parts together and then close the door.
I have taken apart and swapped LCD several times and NEVER had the problem you describe - but its true: the device won't boot when the SIM door is considered open.
Obviously this ONLY happens when someone has taken apart the device (either you or the previous owner) and is usually NOT a solution for those that "suddenly" see the LCD "dead" - which often is linked to the flex-cable connection between the two parts of the device.

man really thank you!
