[Q] Help!! Evo wont turn on

I have been rooted for a while and successfully flashed a few Roms/Kerenels using rom manager. I was flashing the newest version of Myn and one of the "warm" kernels that it offered with it. Everything was going normally the rom loaded fashed the rom and kerenel the phone was reseting then out of nowhere i got the image of the white box and android guy with an arrw as if to say "android taken out of box" I left it like that for about 5 min then took the batt out and tried to reset it. I got the same image then i tried vol. up & power it vibrated 3x and did nothing. My buddy had the same problem yesterday and he got it workin. I called him and he said all he did was pull batt/restart over and over till it booted normally. I tried that about 10x then it would not turn on again. Plugged it in, no response no led light up.
Am I bricked past the point of no return, and if not what can I do to get back in business

Stay calm, pull battery out for 5 minutes and then put it back in, then put charger in and see if LED comes on.

did that batt was out for about 20 min plugged it back in nothing

let phone charge 30 minutes

will do.. from what you know does this sound like a typical brick scenario? I feel like I didnt do anything different from all the other times I flashed roms/kerenels it just kinda flipped out on me this time?

it just happened to me, my phone wouldnt turn on or charge. Pull out battery for 1 minutre, (make sure phone isnt plugged in) out battery in, DONT PLUG IN CHARGER YET.
power phone on, once u see the white evo splashscreen, plug charger in and wait seconds and u will see LED turn on.
keep me updated

No mtter what I do or at least nothing ive tried I cannot get the Evo to respond by turning on or lighting up or doing anything

To get into bootloader, you need to press and hold vol *down* and power. Sometimes mine is finicky...be sure to firmly press those buttons, and keep them just as firmly held until you see the bootloader screen.
If that doesn't work, you might have a dead battery. Can you swap batteries with a friend?

I had this happen to me with my girls evo. Its usually related to overheating. Do you happen to have a second battery? If yu had an htc hero, they have same battery. Worked for me.

This happened to me while flashing the newest EViO. Don't worry, if your phone turns on a little youre most likely fine.

Never got it working or turned on but I took it to a Sprint tech center andt they gave me a new one... It would not power on even when they opened it up. they just replaced it.

Won't power on

Hey guys, I'm having a problem I thought you might be able to help me with.
I had my phone hooked to the charger. When I went back to it a few minutes later, the phone was powered off. There was also no charge LED lit either.
Now, I am not able to power the phone on at all. I get no LEDs when I plug it up.
I have tried taking the battery out several times. Has anyone else ran into this issue.
Also, I am not rooted, I am running on stock software.

You don't get the slash screen or anything?
Have you tried to get into recovery via adb?
We're you rooted / custom rom name?
You sound bricked

I do not get a splash screen or anything what so ever.
This phone has never been rooted. My original phone was, but after an issue with roaming and 3g I swapped it and decided not to root the new phone.
I have tried powering on with the volume button down, but still nothing. My pc does not recognize it at all when I plug it in either.
Also, I have tried 3 different charges and cables as well.

I had the same problems. I just weighted and mess with the power button and the battery. Steps that I did
1. hold the power button for like 5 second w/battery on phone
2. than while holding the p/button took the battery out and than put it back
I did this like 5 time, than it came on.I don't know what it was luck or what but it work for me. All of this happen before I rooted the phone.

Didn't work
Thanks for the input though.
It might just be dead. Maybe a power surge or something. idk.

Well, I finally got it working. It ended up being the battery. When it messed up, it was plugged into my g19 keyboard. This ended up completely draining my battery.
I swapped batteries with my friend to verify this. It than took over an hour to charge my battery to the point of the Orange led comming on.

[Q] Flashed Caulkin's_format_all.zip, will not turn on

I had flashed Caulkin's_format_all.zip and I managed to accidentally reboot my phone before flashing a rom or anything. The phone will not power on, and if I plug it in, the charge indicator will not turn on. I've already tried pulling the batt for 5 minutes with no luck. any suggestions?

I did this once by being too quick at pushing the power button , I was able to reboot into recovery by pushing volume down and power button and then install a backup or you could flash rom. Hope this helps.

problem is, I can't even get it to boot, be it normal boot or bootloader.

If you hook it up to the computer, is it recognized?

Your going to have to borrow someones battery. I've seen people with this problem and for some reason, your phone won't recognize your battery and since it won't it won't charge it. Trust me, stick in a different battery and you will boot right up.

I've tried using my sprint extended life batt and the stock htc batt. neither worked.

and pc won't even recognize it.

So 100% sure that both batteries you've tried have a charge on them? And still no led when plugged in, to computer or wall? That sucks, because it sounds like it got bricked, somehow. I have also accidentally booted after flashing calk's format all from hitting the power button too quick, and as the other guy said, I was able to get to the bootloader by voldown+power, and restore a nandroid. I don't know what went differently in your case, but if you're positive that the batteries you've tried are good and charged, and you get no power led plugged into the wall, then it does sound like you somehow got a brick? Did you try leaving it plugged in for some time? A couple hours maybe, just to see if the led comes on?

Also make sure you are using a wall charger, I know if my battery charge is too low or dead the usb on my computer won't work, I then have to use the wall charger. The led will flash at first before starting to charge. When led is flashing phone won't turn on.
Edit:I just saw wall charging mentioned in previous post. I guess it shows the importance of it

I haven't tried leaving it plugged in. doing that now.

so I took it into the sprint store today and even the techs couldnt figure it out. I've got a replacement on the way. thanks for your suggestions guys!

Well i guess that may be a way of doing it. Completely break the phone if something goes wrong during root

hmmm.... weird.... your phone decided it had enough flashing apparently
First ive seen of a phone completely bricked that wasn't during a radio update.

[Q] What the hell just happened??

So I'm watching tv, and I plug in my phone to charge it a bit because the GPS had gotten stuck on this morning and I burned my battery down to 40%. All of a sudden I hear it buzzing over and over again...like a reboot loop.
So I pull it out of the charger, pull the battery and let it try to boot. Gives the samsung screen for a moment, then flickers, and again to the reboot loop. Holding down power for 10 sec makes it do the same thing, I can't force it into recovery or DL mode without it bootlooping either! At one point I was able to get to the download mode screen, but just 3 seconds and the screen goes black, and back to bootlooping.
I literally did nothing to it. Only thing I did different today was the GPS got stuck (which it has done before), I rebooted the phone, then when it booted again I went ahead and just shut off the GPS. But this was like 20 minutes before this started happening.
So what can I do? Right now its plugged into my computer charging while off, seems to be the only thing it can do without bootlooping.
Running CM9.1 Nightly 9/3 with included kernel and LC8 radio (I think)

My first guess is your battery is shot. i was gonna recommend the power button failure but if its staying off it might not be that. but id let it charge fully then try to boot up.

Thanks, oddly after a bit of messing around finally got it to boot up. Immediately backed up in CWM....seems to be acting OK now. Idk what happened...

i'll guess, the USB connector got short-circuited when you plugged in, and it caused a cascade failure that fried the SD card or something else inside the phone
there was a factory defect back then with the old SGS 1 (i9000m) model, they fixed that after the 3rd batch, everyone with an old phone from 1st and 2nd release batches, were able to exchange i for a new one.
however in your case, that's not a factory defect, but you plugged it wrong (my guess)
because it has happened to me before when i plugged it in, but the battery was still not charging even after several minutes, yet the phone was getting really really hot
then i unplug, and plug it back in and got the sound feedback "tuu tuud" and then it was actually charging after a few minutes
the first time around even though the charging icon changed, there was no feed back sound, and that was the key, it was not plugged in properly.
so after that time, i always made sure to verify to make sure the phone was plugged in properly and not just relay on he visual icon.
check back after a few minutes, to make sure the phone doesn't get very hot, and it actually increased 1%

It happened again today! After a full charge overnight and no problems for the day up to a little while ago, I opened my email app, it froze, then proceeded to start boot looping. I'm in class so I don't have my computer to try to bring it out of it...so yeah that sucks...
I do remember when I got it to charge yesterday it showed it was charging for 20-30 minutes, but after I "revived" it, I found it hadn't charged at all.
I have been using a Nokia USB cable to charge my phone since I got it, because it was longer than the cheapie Samsung cable that came with it...but it hasn't ever caused problems before. And it charged just fine last night.
How long is the warranty on these things thru tmobile? I may just swap it out while I still can.

Also on an unrelated note, I upgraded to the LG3 radio because I was meaning to anyways...

I pulled it out of it again! This time I held the power button while putting the battery in, when it vibrated I let go, it vibrated again, showed the Samsung logo, and then booted like normal

May I ask what rom are you currently on?

CM9.1 nightly 9/3 with included kernel

It did it a third time during class while it was in my pocket, the power button trick didn't work this time, I had to pull the battery after the samsung logo, plugging it back in to get it to boot...but...
near the end of the CM9 boot animation, when it vibrates and the auto brightness kicks in, it started it again! I have yet to revive it...
This is a bit upsetting because I had just got CM9 the way I liked it and I don't exactly have the time right now to mess with warranty and a new phone...I would like to fix it.
There are about 20 different threads on here on how to revert to stock...let me as a last ditch try to revert to stock and see if it keeps doing it...unless somebody has any ideas...

I was working in recovery mode, i super-wiped my phone to see if installing a ROM from scratch would help, and my phone even does it in recovery mode. Warranty time.
So whats the fastest way to restore to stock? Who knows how long I will have after reviving it before it breaks again.

Thanks! got it all done, back to ugly, ugly stock lol...and just when I thought maybe I would have to brick it myself it did the reboot thing again...so pulled the battery and there it sits factory reset.

Charge/Power Issue (please help)

Ok, so I have an HTC EVO 4G and I was doing a factory reset on it because I found that it had malware on it but then the battery died. I go home and i plug it in and it went into recovery mode but as I tried to scroll down, the phone shut down and it wont even turn on. No lights are on either. Can anyone help? I know that the reason it wont turn on has nothing to do with the malware because its a simple notification script. The only reason I decided to do a factory reset is because I wanted to clean out all the garbage on the rom. I'm open to any suggestions.

Have you pulled the battery and let it sit for a while? I've had similar issues before and that's worked for me. Let it sit for an hour then plug it in. Also if you have another charging cable use it. Your usb cable may have went bad. If that doesn't work I'd find a friend with an evo and try their battery.

It worked. (sorta)

So i found a friend with an evo and tried his battery and it didn't work, but we decided to swap batteries so he could charge mine through his own phone. And when the battery was at like 20% charge we put it back into the bricked phone and it turned on. It got stuck on the boot screen as expected but we took the battery out and went into the bootloader and wiped it from there. Thanks man. :good:
