[Q] Blinking red LED & no boot - Sprint HTC EVO 4G LTE

My brother brought me his Evo LTE and said its not working. He's dropped it a couple times and I think his last drop messed it up. When I plug it into the charger the red LED starts blinking (battery is dead) ?. And when I try and boot into the bootloader the capacitive buttons start flickering but the display shows no change( LCD died maybe?) And the red LED continues blinking. Phone is stock never been rooted not sure on the firmware. Fast boot won't pick up device either (excepted since I can't get into boot loader)
Anyone have any ideas? Any help is appreciated

Leave it on the charger for a longer period of time. Battery may be dead.

Wait for the light to stop flashing and then try to power it on.

When it stops flashing and I try to power it on it has no response and sometimes the capacitive buttons with light up and that's it then its off again. LCD is fine because I was able to get into the bootloader for a little but didn't have enough time because I couldn't find the correct firmware for this phone(I have a s3). Now I can't get into the bootloader

Anyone know the min battery requirement needed to ruu?
Sent from my SPH-L710 using xda app-developers app

Not sure there is a minimum batt percentage, I know of some old OG Evo Roms that required a certain percentage. I'd charge her up and try your ruu.

EVO 3D still charging

Hi, I notice lately that my EVO 3D is still in charging status when I unplug the phone, it could be unresponsive with the charge light still illuminated for about 5-10 seconds. Anyone else experience this? Im on stock rom.

It's not totally impossible that they all could have an issue. Are you charging them using a charger and leaving them on it for extended periods of time? That's a killer for lithium ion batteries.

Also, what kind of charger are you using to charge them?

That could be part of your problem too. It's best to use an HTC charger for an HTC phone because they circuitry is designed to charge HTC batteries. It's best not to mix an match them. The amperage could be different.

Well I thought by leaving it on the charger till it turn green I unplugged it but the most it goes to is 70%,can't even calibrate it
Sent from my ADR6400L using xda app-developers app
It's been proven calibration doesn't help. I can even attest to that. Try letting the battery drain completely. Then charge it full while it is off. Then disconnect the battery cable and reconnect it and let it charge to green. Let it sit for 20 more minutes. Or charge fully and reboot your phone.

You need an HTC charger my friend. Charger voltage matters.

I've got the same problem. I bought the wife a tbolt off craigslist cuz she liked mine. It won't charge past 3900 mv. I can take my fully charged battery from mine and put it in hers. It'll show like 30 percent charge and 3900 mv on battery widget. Even tried a power mat in case it was a USB port problem to no evail. Different roms, differnet batteries, differnt chargers
If I knew what was malfunctioning I could change it out with a parts phone I have but don't know where to start
Extended batteries typically don't show the correct percentage. The thunderbolt wasn't designed for them so they don't always show correctly. Once it shows full reboot. After you reboot and charge to full do it again. Do it until you reboot AMD it stays the same. If it doesn't the battery is probably bad. You can check the battery condition in your settings about phone.

Problems loading white light photon.

It all started one day when I did not want to run out of battery switch or connecting it to the power adapter* then try again and it appeared a white light after 3 or 4 attempts at connecting and disconnecting but now took longer to start, what I miss turns itself off and will not turn on and I have to redo the process.
Wait what?

Charging animation?

Is there a way to get rid of it? Every time I charge with the phone turned off, that stupid screen stays on all the time, causing the phone to over heat and not charge at all. I have to cool it down for a good 10-15 minutes before it can start charging again. Any suggestions?

Don't charge it while it's off, it's a problem for everyone with an unlocked bootloader I believe.

Does it actually hurt the phone or battery? Just out of curiousity . I didn't read it in the forums.

The phone overheats (like the surface of the sun) and it actually drains the battery instead of charging it. You have to cool the phone down before it can normally charge again. Even if its plugged in, my battery still went from 7 to 5 to 3 until I cooled the phone down
Sent from my LG-E970 using xda app-developers app
I just noticed that lol. I had a couple times where it showed it. But I was able to reboot to recovery and restart without it heating. But 30 minutes ago I let it sit for 15minutes and it did get hot, much like oc and benchmarking.

Help please!!!!!!!!!!

I was messing around with cm when i couldnt find my folder anywhere. So i decided to flash venom again so i could get my stuff back. In the middle of flashing my phone rebooted and now it keeps bootlooping. When i try to get into fastboot it just restarts after a couple seconds. When it first turns on, i can see it on adb for a few seconds but the phone says offline next to it. Help please!!!!!!!!!!
Hold power and vol down buttons until the phone reboots into bootloader.

I know that, when ever i do that though, after a couple of seconds the bootloader will restart too, thats why i cant get back into recovery
So you can get to the bootloader but it reboots also. Is the battery low?

For future reference make sure your phone is charged before tinkering
