htc 820 is recognized Qualcomm HS-USB QDLoader 9008(COM4) - Desire 820 Q&A, Help & Troubleshooting

About six minths ago, my htc 820 had bricked.
When I connect the phone to wall charger or computer, it only responds blinking a orange LED.
At that time, I tried push a power button, volume - + power button and volume - + volume - + power button, but it failed.
A few days ago, I disassembled the phone cover, and I disconnect battery from the phone. I waited for a day, and I reconnect the battery to the phone. But.......... It didn't work.
Now, my htc 820 is recognized Qualcomm HS-USB QDLoader 9008(COM4). My computer even cannot recognize it correctly. Is there anything I can do to revive the phone, please.

Maybe this will help
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.

I tried this, but failed.

I tried as above. But I failed. I pressed vol+ + vol- + power button, and then released. Then I pressed vol- + power button. Then pressed power button as you quote. Was I wrong?
My htc 820 won't wake up.... and thank you for the reply.

no your case is different, showing up as Qualcomm HS-USB QDLoader 9008(COM4) means your phone has been hard bricked and I dont think there is any way to make it work again as far as I know, there is no fix for hard bricks except for some phones(not D820)
----
but if you connect charger and LED still turns on, there may be a way, take it to a repair store I guess

Thank you for your answer. I want to know what QDLoader 9008 means and you gave me a cool answer. I'll give up reviving htc 820. :crying: There are no htc service center in South Korea.
In the meantime, the phone has been connected to wall charger for 6 hours, but still orange LED blinks.
Something I am doubt about charging process, I found a charger and the phone became hotter. Why they are getting hotter?

Help wanted, is my HOX hard bricked?

Hello all,
I have a tegra hox with cm10.2 installed. this morning i updated cm10.2 to last nightly version. I forgot to flash boot.img so it crashed somewhere during the update process at the first boot. Rebooted the phone to flash boot.img via fastboot, but I selected recovery instead of fastboot. Powered off my phone again to go back in hboot to select fastboot. Surprise, my hox wont boot at all. holding power button or vol - + power button wont turn on my phone.
-My hox was 100% charged
-no noticifation led when plugged via usb cable (tried 2 different cable, 1 is the official htc cable)
-no notification led when plugged via wall charger
-menu buttons blue led wont flash with vol- + power button
-screen is always off, cant boot in hboot mode
-when connected to computer, no detection of hardware changes in devices manager.
I can't understand why my hox would be bricked because I rebooted it.
any suggestion?
I think my motherboard is dead.
I bought my hox last year at launch, s/n:HT23XW....
motherboard p/n is 50H00755-18M and I can't find a replacement board on the internet. Is there others motherboard p/n compatible for the endeavoru? (like p/n 50h00755-47m) I'm considering replacing it by myself and i dont want to send it to HTC for repair, I don't want to deal with their poor service again. Anyone on xda selling their broken HOX for parts?
HTC customer service sucks my one v was acting up so I warrantied it and got one back that runs worse than ny first one.

Sure you have a Tegra HTC One X? Cause mine does not have a blue led!
Maybe you have a hardware failure, have you tried pressing and holding only your power button for more than 5 seconds?

Yes, Tegra 3 HTC One X Endeavoru. Sorry for the confusion about blue led, im talking about home, recent app and back buttons that are blinking blue when holding power and volume down just before booting in hboot.

tried holding power button and all other combination of power and volume button, not booting. when connected to usb and computer, computer doesnt detect anything. red charging led stays off. Im pretty sure my phone is simply dead.:crying:
So im looking for a motherboard but im a little confused about wich one i need. I have the early motherboard p/n, the one with wifi issue. I think i must search the new motherboard p/n, after htc fixed wifi?

HTC M8 will not charge and not start

Hi,
I have a M8 and yesterday I used an old non htc charger for a few minutes. I got a few messages telling me that the charger could not charge the phone. I unplugged it and I rebooted the phone, but it does not want to power up anymore... Power button + volume down does nothing. Power button + volume up brings the phone to life for 1-2 seconds, but it imediatly powers off after I get to see the white htc splash screen. When I plug in the htc charger there is no led indicating it is charging... Besides the fact that it powers up for 1-2 seconds when power + volume up and then powers off, the phone is dead. I kept it plugged in the whole night, but this morning nothing changed... The pc does not see the phone, adb is waiting for device. The only noticeable thing is the sound that windows makes when I connect it to an usb port as if it sees a usb device.
Any chance to bring it back to life?
Nevermind... I have replaced the motherboard. It seems this was the only way to bring it back to life.

HTC One M8 not turning on or charging

Installed Viper Rom 5.0.2 running normally for around a month.
I plugged the phone as usual for charging in night at around 15% battery level.
In morning phone was dead.
Left it charging for a while but unable to switch it back on.
No led comes up while charging.
Did lot of research online and Tried all methods like pressing Power + Up or Power + Down or Power + Up + Down for a while for switching the phone on.
But no response from the phone
Also when I put in the micro-usb socket (when attached to charger or computer) while pressing power + volume up buttons the led flash orange for a second.
Connected with PC shows up as QHSUSB_BULK under device manager.
Please help in reviving my phone.
Thanks

How long is "a while"? Let it charge for several hours (overnight) and try another cable and charger, in case the first one is broken.
Then try to hold power+vol up (or power+vol up+vol down)for a minute or more.
The fact it flashed an LED at all is a good sign. A true brick usually has not LED response.
OoohhhI KNOW...
****...i hope i am doing this rite...
Anyway...what you do is so the volume up , power , and the return buttons all at one time...until it turns on....leave alone so it can reboot.
It should be good to go...
Seriously i found if you do this to any device acting unusual...even for
volume issues...check your devices cpu..if it runs hot a lot,
i found this to be related somehow in the htc..
Call me c r a zy
You have to do it longer...if you have no reply...dude this works ..
Or your phone is Effingham dead dude.....

Naa nothing worked...
led comes on (just for a second) when I keep pressing the power button and put in the cable to the phone.
Also I noted that when I plug in the cable a bit further than the exact slot of charging point led stays for 4-5 second then goes off.
very frustrating it has become...
HTC M8 Completely Dead
Finally I sent the M8 for hardware check and repair.
But unfortunately it was completely dead for no reason.
I left the hope and bought a new phone....
NO Solution at last...
HTC should help me out here...
There phone is completely dead... in just less than 2 years and that to with normal usage (without extreme usage)
I hope someone takes the message to htc for the problems the customers are facing from there devices..
They should just replace such devices with new one for satisfying the customers who had believed in there devices and paid premium amount for the same.

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.

Daughters phone is completely dead, will not switch on. Please help

I have had it plugged in all night, and tried the following ;
Hold power for 1 minute
Hold power and volume up for one minute
Hold power and volume down for one minute
Hold all 3 buttons for one minute
None of these worked.
I have plugged it into a PC but there is no connection.
Is there anything else I can do?
*EDIT* Fixed it! https://forum.xda-developers.com/showpost.php?p=83649851&postcount=7
Its dead phone. What do you want some magic to turn it on? If it dosnt want to turn it on its dead phone and you cant do anything about it.
You might be right, but in the 20 years of owning mobile phones I have never had one that simply "died" before. I've ordered a new charge port as I think it might be to blame.

Pressing pwr + volume down or volume up won't turn on device.
You're not saying if device can enter to recovery nor fastboot or If your device is unlocked or not or if you have some screen as the logo or if you have some vibration, some led blinking, or if you let it charging with screen on (it must be screen burning) or if device was off while charging...
The phone has no sign of life. No led, no screen on. Nothing.

Well, there is not much you can do here, it could be a damage at the hardware level, probably in the port charger or at emmc/motherboard.
Also the overcharging or the kernel panic produced for some overheating can make that device won't boot.
The only you should try at software level is this https://c.mi.com/thread-1479882-1-0.html
I fixed it! After replacing the charging port it still didn't work.
However I read somewhere that disconnecting then reconnecting the battery connector inside the phone would work so I tried that and it worked.
Phone back working fully.
