[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 !!!!!

Bricked. Only white LED. Battery Good.

Pretty sure I bricked my phone. Been digging through the forums all night and can't find anything.
When I plug it into USB I can get the White LED indicator. Only sign of life tho.
Can't boot the phone at all though. Always just a black screen; no backlight.
No motorola logo..
RSDLite won't recognize because I can't get into bootloader mode.
Battery is fine, checked it with a multimeter and I'm at 3.3V
Tried a friend's Defy battery.. no dice.
Any suggestions?

does your friend battery have a full charge on it?
it happens to me before, i turn the defy off, plug the charger, and left it for 30 to 45 minutes and i can boot afterwards. try it, might work for you too.

thanks been trying that out. his has full charge. I also mcgyvered mine and it's fully charged as well.. hmmm

what did you do that caused the bricked phone? did you try to downgrade it from 2.2 to 2.1? because that caused me the same thing, white led, rsd wont recognize it (windows error sound when plugged into usb), and i couldnt solve it, had to bring it back to motorola...
sent from my cm7 defy...

i have read somewhere in the devs forum about a corrupt bootloader experienced by one of our friend there. try to look into that and possibly get you some clues. Another possibility is to remove your sdcard, my crappy class 6 gives me a white lights only boot when im still in froyo, although it happens only once or twice. at this point, might as well try it out eh?

you need to flash with rsd it will read the phone is stuck in bootloader mode download your stock sbf and flash with rsd it will bring your phone back to life!!

make sure you remove battery plug in usb cable then replace battery while holding the vol + key

I actually purchased it from someone who said that it was bricked. I am trying to get back in touch with them to find out what happened but no info yet. I've been trying to deduce what could of happened. But one thing I'm almost certain of is it wasn't water damaged. As I said the battery is still intact and I've never seen a phone go without taking the battery with it. Moisture indicators look fine as well.
I don't get any sounds when plugging the phone into USB. Device manager doesn't even blink. Can you return to Motorola if you are off contract? Any info on how that works? Not giving up yet, just wondering.

Thanks, I will definitely look into that corrupt bootloader situation. I pulled the sd card (been in there the whole time) but it didn't make a difference. There wasn't really much on the SD Card except for a few empty (autopopulated) directories: LOST.DIR, .android_secure, etc.. and the stock froyo SBF file for the phone: p3_jordan_umts_2.2.1..(blahblah).sbf it's a US T-Mobile Defy.
So it likes like maybe the previous owner was trying to flash. Although I don't know why they would put SBF on the SD.

RSD doesn't ever see the phone at all. Thanks for the suggestion. Tried to insert battery after plugged in and while holding vol + key but no difference. Been trying all sorts of key combinations from the forums but no luck there either. The drivers are completely up to date.
All suggestions appreciated! Thanks guys!

any more ideas by chance ?

It's a silly thing, but have you tried pressing the power button AFTER connected USB? Anyway try switching Config-->DeviceID options in RDS.
I was stuck at your point, only white led, hacked the battery and it has been recognised by RDS after some unistall/reinstall... try, try and try again

This happend to me too (black screen, only white led) when i tried to flash some korean froyo. I just removed the battery, connected usb, put battery back, power + vol [+] and RSD recognised it (even if screen was black)

I confirm (I had the same problem...) that your Defy is not bricked :
- don't connect the phone to the PC
- launch RSDLite and choose your SBF
- remove the battery cover (of your phone of course, not your PC ! )
- remove the battery
- plug the USB cable only in the phone
- your phone in left hand, press power + vol.up with 2 fingers of the same left hand
- put the battery into the phone with your free hand, so the right !
- when the white led appears, you can remove your 2 fingers from buttons
- then plug the USB cable in the PC
- RSDLite recognize your Defy !!!
- you can flash...
Sorry for my bad english !

If all above suggestions still fail on you. I would think it might possibly the USB port is broken or some hardware issue which is why it was sold to you as bricked Defy in the first place.

[Q] HTC Desire Charge OK but does not boot at all

Hi All
First thanks for a very good and informative forum.
======================
This was my first post/question and was placed in wrong section. Now it replaced. - Sorry for that!
======================
Information:
HTC Desire
rooted
S-OFF
EXT4 recovery
rom: runnymix...
sd-card partioned(by EXT4 recovery)
AMOLED
Motherboard and ribboncable was changed one month ago on warranty.
Symtpoms:
- Charges normally: orange charging/green full charge. Flashing orange/green without battery
- Cant NOT boot at all
- cant get into bootloader vol down + pwr
- can not be detected buy PC
- Battery inserted and charging: When pressing power to turn on => charge light goes off - and nothing happens. Leaving it in this condition for a while: the phone(mainboard) gets warm.
The phone was functioning perfectly before my son installed bootmanager app. He uninstalled the bootmanager app again without making any changes to the phone. It took long time (like freezing), so he did pull the battery out!!
Any help? Tried a lot of searches, none of them was as my problem.
Thank you

Hi! Have you tried to leave the phone without the battery for 1-2 minutes and tried a reboot?

Take the battery out, unplug it, hold power for 30 secs to get any remaining juice out.
Leave the phone for 24 hours (with battery out etc.)
Stick the battery back in, try again.

What would be the cause for such a behaviour? I'm a little curious (and relatively new to the android scene)!
OT: I've took a look to your troubleshooting guide, good job indeed!

Really no idea, and what I told you to do is not guarantee'd to work, it may help though.
And thanks, it sure has cut down repeat posts about repeat problems by about 90% here.

Thank you all for your replies.
I did leave the phone without battery for several days - same problem.
But I did not try to press the pwr for 30 secs without battery. I will try when I get home.
I tried following:
- take battery out and reset it. then hold vol dwn + pwr -> Nothing
- take battery out and reset it. then hold back + pwr -> Nothing
By the way, if I press pwr to turn phone on, it does not come up, but leaving it for a while it gets warmer.
It looks like the CPU is trapped in a loop and running at full speed!
Could a riff box repair it?

do a battery pull then hold back & power. That usually boots into fastboot mode, see if the phone is recognised with
Code:
fastboot devices
if it is run the 2.3 RUU.

Dear bortak
I have tried. It does not enter fastboot.
command "fastboot devices" returns blank.
command "adb devices" returns empty list
command "adb reboot-bootloader" givers "device not found error"
RUU gives usb error.

have you installed the proper drivers on your pc for it to connect with the phone?
If so, when you attempt boot into fastboot and connect your phone through USB do you get the "device connected to windows" sound, like when plugging in and external driver or usb?
Because if not even that sound gets played it most likely means that your phone isn't even able to get into fastboot or hboot...

windows does NOT play any "device connected to windows" sound at all.
I have all drivers installed correct on my windows 7. My other HTC devices (desire s, wildfire, wildfire s) connects correctly to the PC and I can get the serial numbers of them using "fastboot devices" command.
Now on work, I tried a windows XP - same problem no connection - no sound.
This desire does NOT get into hboot nor fastboot. I think taht the "bootsector" is correpted.
I even used a Goldcard (made thru wildfire) - not working either.
So fixing it thru USB the normal way is not working.
Is there any way to force the device to boot up from SD card??
I have several backups of the phone system on my 8GB SD card.

You have to find a way to re-flash the hboot. That causes the blank screen display. May be a bad hboot install or something :0 Unless you have S-off and can be detected in fastboot, you can reflash hboot, otherwise you will have to try the blind flash method using PB.IMG. Best I could think of.
Sent from my PB99400 using XDA

@Jonicraw, thank you for your suggestion.
Where to get the HBOOT PBxxxx.IMG for this desire?
And how to flash it blindly, since I have black screen and no connection to PC.

Same s**t for me ... I tried everything you try and no results !

Come on experts ... somebody must have knowledge to fix this common problem.
What about an "Unbrick Jig" like the one for samsulng galaxy:
MICRO USB JIG DOWNLOAD MODE DONGLE FOR SAMSUNG GALAXY S2/I9100/I9000
This device may force the cpu to boot from usb, getting it in "boot flashing" condition.

No such things exists for the Desire.
Tell me what state the phone is currently in now?

Yet no solution for this problem...
STATUS for my device is:
Problem solved by changing the motherboard.
I hoped we could find a good solution for this.

I have the same problem but my phone is already on it's 3rd motherboard. I suspect the battery might be the problem but cannot get any answer as to what the voltages should be. I have already submitted a post headed Battery Voltage but it hasn't attracted a reply.

Hi there,
I got the same problem.
Can I send the phone to HTC even if I have rooted it? I also opened it a few weeks ago to replace the broken touchscreen. Do I still have warranty?
Greetings

3. Flashed stock rom via Flash tool (format + download) - like 1.
4. I have unpluged battery
after all, phone cant start... Someone can help me?

I think you have to leave it charging for a while before you are able to turn it on again. Just give it some time

Try another charger/usb cable, just in case the one you're using is defective, or charge the phone connected to a computer

Hi,
I have/had the same problem. The problems started, with the phone powering down, at half the battery level. Then I got a spanish battery overheating message. After the message appears, the problem starts.
I solved the problem like this :
First you have to completely drain your battery. How to do that ?
- Go to the boot-menu (press power on button, and volume up at the same time). Select : Fastboot. The phone will halt. BUT, keep your phone in that state, so it consumes energy. After a while your phone will go out. After that : go again to your boot menu, but DON'T select any options. After a period of ± 5 minutes your phone will go out.
- THEN : remove your SD-Card, and SIM-Card.
- THEN : Connect your phone with the net-usb-charger. DON'T connect it to your PC.
- After 1 to 2 hours of chargeing, your down center button, should start glowing blue again.
I got my phone working again 2 times using this method.
I hope it works for you.

Phone Restored with this method! Thanks pal!

worked for my phone
thank you very much

Not turning on

Hi,
asus zenfone 2 not charging or turning on. just the symbol as attached pic.
when connected to charger it get vibrates and turn on with charge symbol and after few mins goes off. and this repeats. Please someone help on this. Appreciate your help.

if u can acces the bootloader menu (press the power button until the phone turn off then press volume up + power when it vibrate release the power button only) u can install the stock rom using this guide "http://forum.xda-developers.com/zenfone2/general/wwze551ml2-20-40-19420160713-raw-t3437416"
if can´t acces to bootloader u have to do this "http://forum.xda-developers.com/zenfone2/general/guide-brick-soft-hard-bricked-zenfone-2-t3284256"

Hi lineu, Thank you so much. I'm trying the 2nd method which you advised as dont have access to bootloader itself.
during this step, when using xFSTK Downloader 1.7.0, in download status i can see
"Details: BATI:42415449: Batter voltage: 0x45(1294.760000V) The threshold: 0xbf(3.585000V)" and progress bar shows only 8% for a longer time. am i missing something.
My phone is in dead state, i cannot even see charging icon in the screen. Appreciate your help on this. Please help. Attaching the screenshot for your reference.

I think that error is because the battery go to 0%, any chance to extract it and charge manually? With that process u recover the bootloader and later u can use the Asus flash ttools
Or try again the procedure (u can see if the windows device manager recognize the morefield driver when u connect the phone)

how to charge battery manually? as when i connect to the charger it is not getting charge.
