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] BIG PROBLEM -phone dead?!

Hello,
I understand much about computers, but little about phones.
I woke up today and realized i forgot to charge my phone. It had a steady red light on the power button and no reaponse from any button (the screen was black also) so i just took out the battery, waited two seconds till the light went off, poped the battery back in and
i get NO response at ALL?
I figured the battery was just dead so i plugged it into the wall, after ten minutes.. nothing. the light never even lit up indicating it was charging!
SO i pluged it into my laptop, and same result. Windows7 doesn't even recognize it!
If i hold down the power button, no responce (even if i hold it for 2+ minutes)
No lights light up, nothing.
THe cable i have is actually brand new, my sister got a new phone the other day and wanted to keep her old charger and gave me this one.
PLEASE someone help!

if u can access download mode try to reflash the rom

I can't even get windows 7 to recognize it's pluged in!
what do i do?

dl flash tool and install drivers

Where can i download this?
& sorry its making me wait 5 mins between each post

Wait, i just remembered. i used to plug my phone into this computer to use the sd card that's in my phone to transfer files to my other computer (because i didn't have a flash drive at the time)

http://forum.xda-developers.com/showthread.php?t=1351299

still nothing... is there anything else i can do??

try to access download mode, hold "back" button then plug usb while turned of if u see a green light means u can access it

have you tried to charge about 2 hours or more?

See what happened is, i woke up and the light was steady red.
and the screen was all black, no responce with any keys. so i removed the battery and placed it back in,
now i think i might need a new battery? i tried 3 different cables and boxes that go into the wall, also tried them all on two different computers. absolutely no response from phone indicator light nor did any of the computers detect it.
i tried withoout sd card. no result.
tried holding down back key then plug it in, no result.
If i go to a store around the block that sells verizon phones and accessories ect. do you think he will help me troubleshoot?
Maybe i need a new battery.. IDK. this is really frustrating

If your battery is damaged, your phone will power on with the battery out and the power cable plugged in. If your device still wont power on, it's not the battery.

I called AT&T (my carrier) for warranty service but you can call Sony Ericsson directly. I don't know the number but I'm sure you can find it.

Phone suddenly switched off. Dead, not charging, orange led blinking.

Hello all,
I have a htc desire 820 single sim. I had absolutely no problems with baterry etc.. This phone has only 4 months - i didnt put it into water.
I have unlocked bootloader and rooted my phone 3 weeks ago but it was running with no problems. I didnt install any aggressive software that may brick the phone. I just wanted to get access to all files.
So two days ago in the evening i just installed Skype app and wanted to download a file sent by my friend then in the moment that i was downloading my phone suddenly went off - just like there was no batterry etc (i remember it was more than 30% of batterry). I couldn't turn it on - 0 react. I tried to charge him - the orange led is blinking with 1 sec frequency. I left this phone overnight and still nothing - now its 2nd day that its charging and still nothing. I doubt it was a virus becouse i recieved this file on other phone without any problems.
I tried:
-volume buttons - booting in loader = nothing
-plenty chargers, cables = nothin
-charging via pc usb = nothing
-phone is not detected in pc after i connect it (just orange led blinking)
My question is, what actually happened? What else could i do to try to unbrick my phone?
The day before it got bricked i accidently let it fall down on the ground but frim 40cm distance (i have a silicone cover around) = but i didnt notice anything after falldown.
Thank You for any advices.

I think it's battery problem. I had something similar with One X. You can try leave your phone plugged in to charger (try every micro-usb charger that you have in home) for a night. LED should turn green, if not I recommend send it to htc for battery change or to "professional service" in your city Good luck!

Tighten two volume buttons and the power button when you see a black screen and holding down the volume- and power button that would go to bootloader.Telefon must be connected to kompyuteru

Im trying plenty chargers and cables at the moment - for now= 0 results @vuk1963 i tried your method but 0 react from the phone - just like before.. totally dead- just this god damn blinking orange led..
Edit:
WOW... my phone is alive!! All i did now was:
I tried charger from my galaxy core (same amperage like htc 820 = 1A) but i used original cable from my htc charger. The led was still blinking so i decided to "knock" the back panel (around the place where connector from batterry is), then i pressed vol+ and vol- and power button for around 20-30s, then i pressed vol- and power button for around 30s then i released everything, then i pressed power button for 10sec and my phone turned on!!! im so happy! my phone is still on warranty but i live abroad now so i need to send it to my country to start warranty procedure but no im free of this!
Thank You guys for pushing me to try once more the magical tricks with cables, chargers and buttons
Btw.
My batterry is now 100% = that means it was charging all the time?
i don't know what was that but i am happy that it work now.
Thank You guys!

The phone was overheating and it stopped!
Leaving it for a while, then the combination of buttons did the trick.
Great to hear.

Send it back to htc, mine had the same problem. There is no way they will find out u are unlocked or rooted since it wont start. The problem is the motherboard failed. I got mine back with the motherboard replaced.

HTC One M8 Totally Dead (No Access to Boot Menu)

Hello everyone,
Thanks for always helping in times of trouble.
I was using my HTC one m8 normally, playing with facebook. The battery was on 82%. Suddenly the screen frooze then the whole phone went dead completely. Not even a screen backlight. I tried to power it up. It didn't work. It had original ROM, with no modifications whatsoever.
Here is what I did so far, without any results.
- Charge it for few days with original charger and cable directly from the wall. No sign of life. No charging flashing light.
- Charge it with another cable. Nothing.
- Tried to access the boot menu to wipe everything clean. Pressed power+volume down. Nothing. Dead Screen.
- Pressed power +volume up. Nothing. Dead Screen.
Pressed power + both volume buttons. Nothing. Dead Screen.
- Connect it to the computer with updated HTC Suite. The computer said no phone connected.
I using a crappy old iphone now, but would love to get this HTC back to life. Any past experience with similar situation?
Any tips to resuscitate the dead phone?
Thanks a lot for your help.

In some "stuck" or powered off conditions, you may need to hold the button combos for a minute or so, before it actually reboots. So make sure you are holding them long enough.
But the fact there isn't even a charge LED, is concerning. Even in brick conditions, you should get at least an orange/red LED (maybe blinking? Can't remember). Makes me think the battery is bad.
Also play around with the button combos with the charger connected. I've seen a couple folks have luck with this, when nothing else seemed to work.
Additionally, the phone won't connect to PC when powered down; even on a working phone. You at least need to get to a bootloader screen to connect to a PC in any way.

Thanks a lot for your reply.
I tried to do as instructed but it didn't work. I held the buttons on different combinations for at least two minutes but the phone stayed dead.
The only changed I noticed is one point I saw a very weak charging flash then it quickly disappeared and never came up again even when I repeated the process. Does this say anything?

Hard to know if this means anything specific. The symptoms don't look good. Might be bad battery, or other hardware failure.

Help with sph-d710 data recovery.

Rooted and ran https://forum.xda-developers.com/showthread.php?t=1947875 as a custom rom forever ago. Worked flawlessly no issues.
While trying to recover some old photos/messages from the phone. I had a couple random restarts due to macgyvering a different samsung battery at a close to 3.7Volts as the replacement battery I got forever ago was bloated and inop. I was able to salvage somethings but not everything before I decided to get stop getting frustrated and struggling and purchase a new correct OEM battery. After being unable to charge the battery either through the phone (had the dim blinking blue led) or external charger. Froze the replacement battery put it on my external charger and got it juiced up. When it was charged I threw it in the phone and got a black screen and solid blue LED while charging or trying to boot. I can get the led to flash by holding power and vol down, but then it just stays blue.
Power + Vol Down gets me nowhere, Power + Vol Up & Down same deal. So I bought a micro USB jig. Still nothing.
Tried ODIN3 v1.85, 3.13.1, Samsung Kies, some other Odin 1 touch. Can't get the phone to connect to pc or post a screen to recovery. Using Samsung USB Driver Version 1.5.65.0
So im trying to preserve the data that is hopefully remaining that I want, and get the device to boot.
I can only assume based on searching the forum, that my phone is hard bricked and potentially the only option to recover anything from it at this point is a JTAG. Or I'm SOL.
