[Q] Unrooted Evo won't boot

[godsmacked4653]

My friend has a completely unrooted, stock Evo. I'm not sure about the hardware version, and I hope it doesn't matter.
They were texting and using navigation with the phone plugged into a car charger, when it turned itself off and now won't turn back on. After a battery pull, it'll boot to the splash screen, but then shuts off again. After that, it doesn't boot at all.
I've tried getting it into fastboot, but I'm not incredibly familiar with the Evo. So far, no luck.
I have a rooted Incredible, so I've tried all the little tricks I've used to fix my phone.

So, any ideas? Bad hardware, bad software? Get it replaced?

My last Evo (I'm on my third one) was unrooted & would do something similar. At first it would just reboot itself, but then the screen would freeze & flicker and I would have to pull the battery then try to boot it up. Sometimes it would take 10 or so tries, but after it would boot up it would eventually do the same thing. At first doing a factory reset would fix it but then that stopped working.
If it's similar to my issue then it will have to be replaced. If your friend has insurance then they'll replace it for free since it isn't user damage. Until they get a replacement, try booting into fastboot & selecting reboot from there instead of just powering it on. That worked for me a few times.

I had tried the fastboot reboot, but it wouldn't even get that far.
Turns out, the navigation and texting had drained the battery faster than the car charger could charge it. After a full charge overnight, it's booting up fine. So it was fortunately a very simple problem.
Thanks for the reply, though.
