[Q] [Help] Defay dead - what could be the reason and how to rescue?

I've owned the DEFY for over two months, it is rooted but not flashed. Installed many apps and it had been working fine.
Today it suddenly go black when charging. Then, when pressing the power button, nothing happened. At first, when it was plugged into the PC USB port, the white LED was on. But later on, even the LED was always off.
Connected to PC via the USB cable, take the battery off and put it on again, the USB connecting and disconnecting sound was played on the PC. The Windows XP hardware manager briefly showed "Motorola USB device" and then it disappeared.
The screen is always black. Nothing seems to happen when pressing the power button, power+volume up, or power+volume down.
Please help!

I borrowed another DEFY and charged the battery to 100%. The problem persisted. The battery is good, for it can be used with the other DEFY.

Did you overclock your Defy? If yes, this might be your answer!

No. It has never been over-clocked. Just normal usage all the time.

If it can't even get to the recovery (hold volumn down) or bootloader (hold volumn up) screens, there's probably nothing can be done other than sending back for repair.

DEFY won't start after Flashing Chinese Froyo ROM
Hi,
I have the same problem: tried to flash Jboogie3 BlurlessGinger(2/16/2011).
Donwloaded the chinese rom from this thread: http://forum.xda-developers.com/showthread.php?t=895448
Flashed with RSD Lite: Result was "finished" and "PASS".
Pulled out the USB-Cable, LED light went off, but nothing happend.
Tried to reboot but no reaction from my DEFY. Even after pulling out the battery.
No Recovery Boot and no Bootloader Mode. :-(
Can anyone help please.
Thanky you in advance,
hartmuna
--------------------------
Hey guys,
luckily RSD was still able to connect to my DEFY even though it seemed dead. I reflashed the PL Froyo rom and it booted up smoothly. So be aware of the chinese rom!

[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.

@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.

Had the same problem. Mine could not charge at all and could not enter fastboot/recovery. Send the phone to HTC. I got back the phone with a new battery.

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

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

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.

Desire HD bricked!

Hey guys,
I've flashed quite a few ROMs in the past 2 years. Today, I flashed a new ROM and it worked fine. After that, I installed Nova Launcher and changed the density to 160 and the phone asked for a reboot. However, it isn't booting after the reboot. I can see the white HTC screen for 1-2 seconds, after that the display dims and then turns off. Can't go into the bootloader or the recvovery. The phone charges normally (can see the orange light) and on connecting to the PC, it gives the successful connection sound. Any tips on how to fix this? I've done S-OFF long back if that helps. I've tried removing the battery and inserting after 5-10 mins, however I'm still getting the same output.

EDIT: Guys, just noticed that the phone isn't turning off after the HTC white boot screen. The backlight starts and then turns off after a second, and then starts again for a second and this keeps repeating..

Pull the battery.

Did you reboot holding power and volume-down?

Yeah, tried all possible combinations incl the usual power + vol down. The HTC logo appears for 5 seconds and then I can only see the backlight on the screen for another 2 seconds. This backlight then turns off and turns on repeatedly every 2 seconds and continues till I remove the battery again.
In short: No bootloader access, no recovery access. Just can see the device after I connect it to pc and type adb devices.

UPDATE: Fixed. Used the adb, on typing adb reboot-bootloader, I could access the bootloader. Thanks guys!

Same problem, Please Help!
My DHD, passes the HTC logo, then goes blank. The backlight doesnt go off, its just blank and remains like that indefinitely.
There is no charging led light when on the blank state,
The blank state does get detected by the computer.
Fastboot Commonader V1.51 says no fastboot device detected.
(P.S. My volume keys are water damaged and do not work, so i cannot use Vol- and power)

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
