Phone: HTC One XL (Evita)
Condition: Always taken care of properly, never faced any issues. Phone has never been dismantled.
Will try to be as detailed as possible: Was running Paranoid Android 4.45 flawlessly for a few weeks. Latest hboot (2.18) etc. Phone was not charging over night - woke up and was checking Gmail and the phone suddenly turned off, while it felt a little warm. OTAs are not automatic, and not software updated happened in this duration. Wouldn't turn on, no LED on attempted charging, doesn't get detected on plugging into any computer.
Also, not sure if this is helpful, but I have an Anker portable charger and that is most definitely 'charging' the phone. While the LED on the phone itself isn't coming on, there is an indicator LED on the charger that only comes on when a device is actually being charged. And the charger's LED goes off automatically as soon as the phone stops accepting the charge.
Example: When my Nexus 5 is plugged in, it stops charging sometimes (LED off, on charger). In that case, I have to shake the charger to restart charging, which also makes the LED (on charger) start glowing again.
Also, Seems that at least one other person has faced the issue I'm facing. Details about that instance and ROM are on another forum - not sure if I'm allowed to post links to the forum.
Any recommendations? Pune contacts for someone who can help?
