The fact that he's posting in the HTC-EVO forum should give a pretty solid clue.
@OP, just do a search on here for white screen or boot loop and you'll find a lot of cases of this and some information on potential fixes

HTC Incredible black screen with boot loop, Need help

Ok guys, I've read & search before I made this thread but I seriously need help or suggestions.
I brought a HTC Incredible Droid from a guy for $40. Has Black screen & always says "droid" every minute or so when it's booting up normal. It's AMOLED screen, The screen doesn't flicker or no white lines.
So I'm trying to recover this phone back from the dead. I've tried booting into HBOOT with files i've google & from off this site but no luck as far as I know. The light comes on when it's charging & from normal boot, it vibrates once so it's working normal from what i've read. Need help from the XDA gods to bring it back to life.
Sorry If I post in the wrong section.
Boot into hboot (pull battery, reinsert hold vol down and power at the same time) and see if you are s-on or s-off, and what radio version you are on? It will be at the top of the screen.

Thanks for the reply! it doesn't show anything, it's a blank screen with action going on in the background. I don't know if it's s-on or s-off or what radio it's on, I brought it from someone. How can I check it?
If you cant get into hboot the phone is bricked.
I had a similar problem when I flashed a bad ROM to my droid incredible.
There is a way to get past this seemingly bricked problem but you will need some help of ADB and a lot of patience.

Help phone wont turn on

Hello this is my first post by the way and i really need help please i just rooted my lg nitro hd and was flashing the CWM on it and when i turned it off to check if it worked it will not turn back on at all not to cwm or regular boot please someone help me i just got this phone 2 days ago.
thanks in advance
What do you see when you turn the phone on?
does the charging screen come up when it is plugged in?
it doesnt power on at all and the charging screen doesnt come up either
mine too,it doesnt power on at all and the charging screen doesnt come up either,
anyone help!
I don't know a way to fix this problem but I have seen unbricking threads for this phone that may help. I'm not sure though because I haven't tried them. I did however also brick my nitro two days after I got and I brought it back to at&t and acted like I had no clue what was going on. Mine was stuck in a boot loop and possibly fixable but I needed it for work and didn't have time as I was on my way to work.

Hey try pulling the battery then reinserting it with USB plugged in to see if you can breathe any life into it if you can get anything to show on the screen that would be the first step then after that there may be a chance of rescue also try to let it charge for a while and come back to it, I brought a phone back because nothing would show up on the screen but when I brought it back to the store the Guy got it to bootloop if you can at least get it to do that you can work on unbricking it further

Something like this happened to me when I did a battery pull. My battery wasn't dead at the time either, it had 37%. I ended up sending mine to LG for repair or if you have AT&T, you can get it fixed through them.
I have the same problem, mine just stucks at LG logo and then loops, i don't know what to do, please somebody help us!

Hold down volume down plus power until it goes to the factory reset screen. Press power to "reset" which really takes you to CWM (if you're rooted and have CWM installed). Then from CWM, do a factory reset/wipe data, then flash the zip/gapps (for CM 9), or another ROM if you prefer.

Agree with kernelpanic. Sounds like a hardware failure. AT&T also has device support centers in certain locations that can swap out your phone in some cases.

Hi! thanks for answering!
Yes, I have CWM installed, when I try to enter with volume down and power, it ask me to click power twice to confirm (as usual), but then when CWM is going to boot, the phone resets, and loops again at the LG logo.
I already tried the unbrick method used here in the forum, but I have a problem with the R&D Test Tool, because when I try to click at "Upgrade Start" in CSE web upgrade test, the program opens LGMobile Support Tool, instead of the screen of "country and language", and finally, when I try to update via LGMobile Support Tool, it doesn't found my device (already put in Download Mode in USB), I don't know what to do, please, any information will be greatly apreciated.
Thanks in advance!

[q] help pleeeease

I don't know how, but i wound up on the bootloader screen, and no matter if i power off or reboot, it still brings me there only. Then i selected (tried) HBoot. Now i am stuck there. I am on stock only, never unlocked. On 1.29 (SH25). There are following options shown: Fastboot, Recovery, Factory Reset, Simlock, Show Barcode and Image CRC.
All I want to do is boot the phone into regular stock. What shall i select besides Factory Reset? Kindly Help ASAP.
Many Thanks in advance.

have you tried doing factory reset? i know you will lose stuff but worth trying to see if the phone will work again..well should do..my first thing would be to do factory reset since you tried rebooting.
or go into bootloader and try fastboot reboot (command that is)

It allows you to perform various functions on your phone via USB and a PC operating system.

what he said basically
use the following commands
"fastboot erase cache"
"fastboot reboot" and see what happens
Oh well, I tried Reboot, Fast Boot as well as Factory Reset. Nothing seems to work . They all restarts the phone and brings back the bootloader screen.
While restarting, right under HTC logo, it momentarily displays: "This build is for development purpose only. Do not distribute outside of HTC without HTC's written permission. Failure to comply may lead to legal action."
Guess i will have to bring it back to the retailer.
Seems like you have unlocked and relocked the bootloader.
You will need to download the correct imagine file (RUU) for your phone and follow instructions.
Can you find a guide on the internet?
You will probably have to unlock the bootloader again to get some information from your phone in Fastboot mode.

I tried Factory Reset, It stayed on the splash screen for more than 5 minutes. Then i pressed and hold power button. It restarted the phone back to bootloader screen.

No, you should see some action before 5 minutes, sounds like you need a few recovery procedures.

Hmmm, that's interesting, sounds like you might need to unlock it then and recover it yourself.
Or as you previously said take it back to whomever supplied it to you.

do not know what recovery would do as i never used the stock recovery before.
if it still giving you issues and factory reset does not work i would suggest give it back to retailer asap

Yup, factory reset is NOT doing anything, just froze on the splash screen. Guess will have to take it up to the shop. Hopefully this time it will be easier (last time i had very difficult time to get replacement for my HOX with wifi hardware fualt).
You have been real helpful. Thank you so much.

Phone Stuck in Boot Loop (SDS?)

Hey Guys,
I was playing Boom Beach on my commute this morning (which is slowly taking over my life) and my phone just randomly shut off. This has been happening a decent amount when I had multiple apps running after the latest update. This time however, when it got to the "Samsung Galaxy Note II" screen it would try to boot up to the ATT screen, fail and then restart.
I've tried pulling the battery, putting the phone in the freezer and, as a last resort, went into recovery mode and cleared out the cache and the deleted all of the user data....no dice. Now it just gets to the "Samsung Galaxy Note II" screen and either loops or just hangs there.
I am under the assumption that I am screwed here and was wondering if anyone had any ideas on how I might fix it. I think my only shot is to flash a new firmware from the recovery menu...does anyone have any tips on how to do that? Just get me on the right track I guess
Thanks a million!

This seems to have bricked my phone completely. It won't even turn on and can't manage to charge the battery without freezing. Thank you for trying to help me out with this, it was much appreciated! I'm very excited to never buy another Samsung product again and get a phone with this cool thing called build quality. Bye bye cheap plastic, clunky interface and slow performance!

[Q] twrp issue and boot problem

Ok heres the deal. my daughter got ahold of my kindle. we i dont know what she did but she ran something that much i can tell. i powered it off then back on. when it booted, it booted into twrp and ran a recovey script. this is where it hangs up. so i held the power button down to reboot. when it rebooted it boots back into twrp. but it boot to the main menu. i rebooted the kindle though twrp. this time it boots up normal. after it is booted up it shuts down and reboots into twrp back the the recovery script page in twrp and hangs up. i have tried wiping the cashe and dalvick, then reintalling a back up. but the problem is still there. if some one can help me that would be great. it does charge so i got one good thing going for me. if worst comes to worst, i guess a factory reset and then redoing all the work i have done in the past.

the update requires a compatible recovery to install, if recovery is not compatible, it will get stuck in recovery.
