[Q] Phone won't turn on! Vibrates and Green LED only

morning guys/gals,
last night i put my phone to charge, woke up this morning and turned on the screen and it said "no sim card detected, reboot device". Now when I rebooted the device all I get is 5 vibrates and the green led light stays on. Screen stays blank!!. I tried battery pull several times, tried vol-down + power but all I get is the vibration with the screen off and the led on.
When I hook my phone to the laptop I can't access it via fastboot/adb, it shows up as "Qualcomm CDMA Technologies MSM" with a yellow exclamation mark in the device manager. I tried forcing different drivers on it (e.g. adb composite, bootloader) but none let me access the device via cmd.
Now I got clockwork, running latest android revolution 2.0.8, device is radio-soff and eng-soff.
What am I to do now? Is there possibly a hardware fault? If I cant get to access to the device to restore it to stock, I'm going to struggle to get the device replaced, isnt it?
any help is very much appreciated!!!

What ROM were you running on it Prior to this happening?
was there any apps running in the background?
the Vol - + Power should get you into bootloader, if you cant get into bootloader I would be tempted to say fooked, and take it back to the shop as they wont be able to boot it either,, but thats the defeatist attitude...

ok very strange, I was playing i around with the phone, now if I pull the battery and connect it to the usb cable the light went red instead of green and it automatically booted in clockworkmod (thanks to the "bug"). vol down + power didnt get me there so once I was in clockwork I thought let me wipe battery stats (eventho I wiped them when rom was freshly installed). I thought the device is unplugged but the green light stays on (after full charge), maybe battery issue. Now after wiping battery stats I'm able to boot the device again.
Thats weird but hey atleast my device is back on track. Either faulty battery or some software bug, either way if anyone experiences a similar issues (phone wont boot, just vibrates 5 times and green led), just pull battery, connect phone to usb cable on your laptop or wallcharge and clockwork should boot up, wipe battery stats and u should be fine

You gotta love that ClockWorkMod recovery image

Hi
I had the same issue yesterday. After one hour of stress(I have DHD for 4 days), I finally find out solution which worked for me:
1.) pull out the battery from phone for at least 10 minutes.
2.) connect phone to the charger.
3.) pull battery to the phone and wait
4.) after orange light recovery should boot up.
5.) wipe battery stat.
6.) enjoy your phone again.
Hope this will help to somebody .

May I know why such incident occured?

Thanks for your reply! this worked for me, allmost.
I did however had to press the Power button ONCE to start the phone.
- Plugged in charger, pulled in battery, (orange light was turned), then after 25 sec I pressed the Power button - and Voila! My Phone started as normal.
I diden't need to do any "Wipe battery status", but after reading about it I did it anyway. It was'nt necessery though in my case.
THanks a lot you guys for your replys! I thought for sure my phone was dead.

try sptool to format your phone except the boot loader then try to flash the phone, if its not working then change the mother board !!!!!

Desire Z wont power on :(

Hey guys,
Running ILWT CM7. Flashed about two weeks ago. My phone has been working fine except for the past few days where it's been constantly freezing, requiring a battery-out and turn on, and rebooting on it's own.
Last time it froze, I removed the battery and turned back on, and it got to the "htc" logo and froze. After ~25minutes, I took the battery out and tried again.
Phone seems completely dead, won't respond to power on, volume down and power on, no lights come on when charger cable is plugged in. When USB cable is plugged in and no buttons or anything on the phone is pressed, my laptop attempts to install drivers.
Tried leaving battery out for 30minutes and trying again, but no luck.
Any suggestions?
Cheers!

Stuck in RUU mode?

Looks like your phone is stuck in RUU mode.
In RUU mode you see the silver "HTC" logo as long as your phone is connected to your computer with an USB data cable. No charging lights will show in this mode.
You can use the following command to boot your phone to Android:
Code:
fastboot oem boot
When that does not work, because your partition table or system partition might be corrupted, then you would have to use the correct RUU (Rom Update Utility) for your phone to get it back to a working state.
When you have a bricked internal memory chip (emmc) than nothing will work properly to restore your phone to normal working conditions.
In the case you have an engineering HBOOT you could boot a ROM from SD card, but that is a far shot.
Best regards,
Catherall

Thanks for the help
When plugged in with the USB cable -> computer, I still get no response from the phone itself. Screen doesn't turn on, still seems dead. My laptop still says "Installing device driver software" to no avail, and phone is still dead. No lights, screen is off, nada. As though it was powered-off.
ADB Devices lists nothing, and fastboot oem boot hangs on <waiting for device>.
Am I out of luck? I could send the phone off for repair, but as I'm rooted I think warranty is void.

Windows seems to need a driver installation for using fastboot. Did you try to automaticall install device driver software? Have you installed HTC sync on your Windows computer?
When your device does not respond at all, and even refuses to connect in fastboot, then nobody can tell that you have been rooted.
Best regards,
Catherall

Sounds like your EMMC is fried, as of now I don't think there's a solution other than sending it back. Many say HTC accept and fix it even though it is s-off
Sent from my HTC Vision using XDA

did you get this worked out? i had a similar problem, ended up booting into fastboot by holding the trackpad and the power button, then just selected reboot and my phone powered on like nothing had happened, i was running the same rom.

Hey, did you alreasy tourned your phone to the fastboot mode?
Or does your device still have a black screen during boot?

I rooted this phone and when I was done trying S-OFF, phone would not respond to anything. It would only blink the orange notification light when I pressed Power and Vol+, or it would stay steady green with both Vol keys and Power. But the phone screen would never turn on. So after trying for hours to figure it out. I finally took the battery off, plugged the phone held pressed the power button and then put the battery in place the phone finally turned on and it worked. I turned the phone off again and it was doing the same issue. So I did the same step but this time with power and vol- to get in the bootloader and changed the hboot version to Desire Z. After that phone works perfectly, turns on and off with out any issues.
I did have to try the trick a couple of times idk why but it would work once in a while not everytime i tried it. Hope this helps anyone who also ends up with a similar issue.

Dead Lg G3

So I bought a used G3 knowing about the issue it had; it didn't boot. I thought I could find a workaround to this but the phone doesn't boot, doesn't enter recovery or download mode. All the info I have is that when I take off the battery the pc sees it as an unknown device, while it's connected I press the power button for several seconds and it disconnects from the pc, reconnects after several more seconds of pressing the power button. Screen remains dead. Seller told me he had a perfectly working phone before he tried to root it and it never turned on again. One more indication is that the LED notification only flashed red a few times when I connected it to the wall charger and that was it. No LED working after that. I'm open to any suggestions though I guess I'm here for someone to tell me there's no hope reviving the device. Thanks in advance!

Same proble with mine but i bricked mines when update to lollipop and never turn on again . still waiting to some one help to revive my LG

If I come across any solution I'll post it here. In the meantime I've tried the following method on a freshly formatted laptop and I still get "Unknown Device" in Device Manager..

same here
same problem, someone told me that if was the board or something like that and that it only can be fixed with a complete replacement of this, also, that it could be fixed with linux using comands to install .APK or .TOT.
linux sometimes sees it as Qualcomm CDMA Technologies MSM QHSUSB_BULK, using a virtual machine of linux ubuntu, windows 8.1 sees it as unknow device
LG dead since 3 months ago.................. i wasnt using the phone at all when this happended so........... :crying:

I tried using a boot usb drive to see if ubuntu saw the device but it didn't. Maybe there's some things needed that I didn't do. The thing I don't understand the most is why do windows see it as an unknown device only with the battery out while if I connect the G3 with the battery on, it doesn't show anything on device manager..

Hi there.
Please check these 2 threads out and see if any of it will help you. The one for the G2 can also be used for G3.
Here are the links:
http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091 With this technique you would have to find the software online somewhere but this method does revive dead G3 with these symptoms.

If I helped somehow, hit the THANKS button.
Good luck!

The thing is I can only get the device to be recognized as an Unknown Device in Device Manager and only with its battery out. If I keep 'volume up' pressed nothing happens, it's only shown after I simply connect the USB cable and it pops up after 10 seconds or so. It's very consistent in the way it behaves..

A small update, sometimes when I pull and put the battery again, I connect the phone to a pc while holding down vol- and the pc makes the connected usb sound while the phone led is blinking red for a couple of minutes, then it stops. That's about all there is concerning the phone giving signs of life..

Htc 816g Bricked and wouldn't connect to PC anymore. after installing recovery

Yesterday i attempted to install a custom recovery on HTC desire 816g. using fastboot command the process went fluently in fastboot mode but when i tried to open the recovery from hboot the screen got stuck at htc logo. After a while i gave up soft reset the phone using hardware buttons and since than the major problem began.
On restart the device screen turned blank as in didn't display anything and the red notification led stayed on. It stayed like this forever so i plugged in the charger and reset the phone again . Now it showed me just the battery icon with charging sign in the middle with no signs of how much it is getting charged or how much it is charged. It just stuck on the charging on and of course the red notification led continuously turned on. when unplugged and restarted it again stayed blank with red led on forever. SO i thought if its a mtk chip i would just reset the device by inserting the stock rom using sp flash tool. So i reset my phone where the led turns of for a second and turns i believe which is resetting it and connected the usb and nothing. windows does not simply detect the HTC anymore. SO i opened the device manager to see if it at least shows up as an unknown device in it but nothing. It simply does not show up. I have tried everything. restarting it connecting the usb unplugging the usb before restart on restart after restart all possible combination nothing works. But the led keeps strongly flashing red. So i thought its the battery problem. I kept it as is with red light flashing it discharged on its own and now when i attempted to start it the red led was blinking now. So i put it on charging overnight. And after all efforts its still the same. I need your help the most. Cant loose a phone now. Is it permanently bricked?
