evo not charging, turning on

[seanlb]

My evo will not charge, light the charge light, turn on, or respond to any functions. Two sprint stores said they have never seen this before, and they offered to give me a new one for free. Only problem is that they're out of stock and I'm off to Vegas in a few days. I can't not have a phone in Vegas.

I've held every combination of buttons.
I've taken out every item (battery, sd card) and then tried every combination of buttons.
I've had it plugged in and tried every button combination with every item out.

The only thing I haven't done is leave it alone and let it charge, but I'm finally able to do that now.

I rooted my evo 2 days ago with no problems. I installed titanium and backed everything up. then I froze some apps.

Last night the phone was very low on battery power so I had it plugged in all night on my closed macbook pro. When i woke up my evo was still on and fully charged. I got in the car, plugged in the power and the headphone jack. 30 minutes later it cut out in the middle of a song and has not turned on for about 12 hours.

if someone helps me I will give them all of my Vegas winnings.
please help.

I just talked to a sprint technician and she said that something must have shorted when the evo was plugged into the car adapter.
I can take it in tomorrow and have her look at the mother board.

Would rooting the phone make this easier?
I'm asking because if I get a new phone, I'm going to root it again and just make sure my charger is legit. Maybe when I turned the car on it surged the phone. I don't know.

A few years ago, I got one of the earlier touch screen Magellan GPS units. In the owner's manual, it specifically stated that the charger should be plugged into the cigarette lighter after the car was running to prevent a power surge during startup.

Meh, I dunno...

- The car puts out 12volt (ish) DC
- This gets converted to 5vdc
- The phone will draw up to 1amp

I can see how your charger might pump out more than 5vdc... but you said that it went out 30 minutes after it was being charged. This isn't a "surge" (which doesn't make sense to me) behavior... if your phone died because of that, it wouldn't wait 30 minutes for that.

So either, your charger pumps out more than 5vdc, and it a bad unit, or your phone shorted for some other reason unrelated to your car charger.

Lastly, rooting has absolutely nothing to do with your phone shorting out or changing the mainboard. UNLESS you overlocked the bejeezus out of it... and in that case, you hopefully would have known what you were doing.

Thanks. The guy at the tech place today said that it didn't have visibly burnt components on the mobo, but that it might be a capacitor. He said that car adapters are really bad for phones and that it was the culprit.


I did not overclock it at all.

They're sending me a new one. I just hope it gets here in time.

Have you tried a different charger? I know that sounds stupid but just making sure.

what kind of charger were u using? just curious if your using a cheap knock off from ebay or a brand name one.

 

[seanlb]

I was using a charger from a gas station. Hopefully that was the problem. I have a new one now and I have not used the phone charger, or rooted it.

I'm going to root it today and see what happens.
Wish me luck.

evo charging

I noticed that if you let the battery drain completely , cheap chargers act up & not allow charge initiation

this happened to me a few times.

When I used the original HTC charger, it kicked up indicating the charge LED light. ::hew:::

Hmmm, try going to the unrooting thread and running the ruu described in there from fastboot. To boot into fastboot, hold volume up and power.

Then follow the guide to using the ruu.
