Orange light blinking and phone won't turn on?
Hi guys give this a try next time you're phone has a orange blinking light. Especially for those phones that have a non removable Battery in there phones like htc 820 or an iPhone. Ok so unplug your phone press the power button 10 times at 1 second intervals to discharge it, then hold the power button for 16-30 seconds until it turns on. Then plug it up to the charger to properly charge even if it says it's charged. Hope that helps you guys out.

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.

Hii...I'm facing exactly same problem...Did you fix it?
My phone goes to bootloop everytime I start it. HBOOT and Fastboot are working fine although!

Hi! Bought the HTC One X today. After turning on he offered a system update. Phone was charged up to 50%, then an update was launched. Phone stayed pluged in to charger. Green arrows appeared for 40-50 min then screen gone black and thats it. No volume up/down + power buttons, no power button for 10 sec can't help.
But! Phone is visible like a device by computer, when pluged over usb. And led is yellow when pluged to charger.

Hold volume up and down buttons in together and press power button phone should reboot after 5 seconds, then hold volume down to enter hboot and do a factory reset.

HTC M8 would not boot, black screen, no charge led

I have had the phone for around a year. Haven't flashed or rooted it to non-official ROMs. It had boot loop issue a few weeks ago which was solved using RUU to the official ROM. It worked fine until today.
Today, while using the camera, the phone stopped responding to touch and a message said that camera is not responding.
I shut down the phone using the power button.
When trying to restart the phone, it did not light at all.
The phone had a high charge when this happened.
Connecting to the wall does not light up the charging LED.
Using power + volume down or power + volume down for several minutes does nothing. Neither does shining light on it.
When connected to the computer, it loops Connected -> Unrecognized USB device -> Disconnected after 20 or so seconds.
Any ideas?
Thanks!
Try charging for several hours (overnight) and see if charge LED appears. Also try the button combos again after charging overnight. Use wall charger (not connected to PC, which can be too slow).
Try the button combos with and without the wall charger attached. Also try power + vol up and vol down (all at the same time).
When I connect it to the wall for a long time, the LED sometimes flashes orange and again a second later and the loop repeats every 20 seconds, similarly to the rate of the unrecognized device when connecting to USB.
Last night, there was a stage where it got to a constant orange LED but in the morning it was back to nothing or the slow double orange flash.
It is still under warranty and if it doesn't get fixed by itself, I'll hand it in for testing on Sunday.

Z5 Premium Dual - Does Not Turn On...

I did a software update recently on my Z5 Premium Dual E6833, and when I look at it later it was off! I tried to turn it on, but it was unresponsive. No signs of life at all. Its completely dead. OFF button in SIM slot does nothing, even if I hold it for more than two minutes. No charging LED light when connected to wall charger. When I plug it to my PC, it was being detected as "Unknown Device". Tried loading some ADB driver but it was not accepting it. Tried few different chargers and cables as well. Also Volume Up + Power does nothing at all, same for Volume Down + Power...
Looks like it runs out of charge when it did a software update, it was still have more than 50% when I started the software update. ..
Can anyone guide me on what to do next? I am in the middle of the desert at the moment for the next three weeks, and no access to any local service center. Thank you in advance for any advice that you might have... :crying:
i am worried since you did the volume up + power button trick!
charge your device over night , hold the volumeup+ power button for atleast 15 seconds , the device must jerk thrice! remove fingers on second jerk . the device will shutdown . at this point connect device in flashmode and flash the kernel!
Thank you for your reply, appreciate it! I have tried that trick of holding the Volume Up + Power even up to 30 seconds, but for some unknown reason, it does not vibrate at all. I have tried it on numerous occasion but the vibration was not coming at all...

Hard bricked HTC one M8

So it has been 2 years since my M8 got hard bricked, however staying home during this quarantine got me thinking if i could try and fix it or not, so 2 years ago
i took my M8 out of my pocket it was not responding and slow so i restarted it and since them all my phone shows is a black screen, when i try to charge it the battery icon doesn't appear still the same black screen, just for a brief second after plugging it to charge the orange light up there flickers and then nothing more, when i connect it to the pc it's recognized as qualcomm hs-usb.
My M8 was with unlocked bootloader, but S-ON, had TWRP installed on it.
Maybe you can replace a new battery, which will give a hope.
Exactly the same issue here, but tried a new battery, no go. Have you managed to find anything since last April ?
When the brown light blinks and doesn't turn on it usually means the battery is too low to turn on the phone to display that its charging, normally it takes a few seconds or minutes depending on your charger, if it does turn on in a few minutes in my experience it means your battery is dead.
Another trick I was told about is holding the power and volume down button for 15secs while plugged in then hold the power button for 10secs.

Any chance you could confirm that when plugged in to the pc it's recognized as qualcomm hs-usb. I got a feeling the bootloader got creamed, i believe it should be showing up as a HTC something...

Have you tried to leave it in the charger and see if the blinking brown light turns green indicating full charge, alteast that way you can rule the battery out as the problem.
From the little googling this is the best answer I could find
Qualcomm HS-USB QDLoader 9008 is all that is left from my M8

One Plus-3 Black Screen. No LED No Vibration. Hardbricked?

So I had kept my oneplus3 on charge at around 10:00 Pm yesterday and fell asleep. Woke up around 12:00pm to see it was fully charged so I unplugged the charger kept the phone beside me and went to sleep. Today when I woke up I saw that the phone has a black screen and is completely dead. The LED light is not on. Plugged into the charger no response. Tried holding power button ..nothing. No vibrations or home button lights
Currently, there is nothing going on with the phone. No flashes on screen no LED. Absolutely nothing. Tried connecting to laptop (windows 10) dont see anything. It was working perfectly fine last night and i had used it for nothing but music then.
Question is.. is the phone hard bricked or completley bricked? what might be the reason? I searched youtube only to find 1 person with similar problem who had said that he kept the phone for 48 hours and when it was completely discharged he pluged in charger again and it started working.
I am confused. Have a lot of work documents inside and what if it stays the same after 48 hours?
Appreciate any help on the matter
update: Tried plugging in the charger a few min ago. The led turns red and Vibrates. Nothing else
Update 2: so after 24 hours of setting the phone aside. i plugged the charger and it went into charging. But now am facing a new problem. My bootloader is unlocked and the power button is busted hence whenever I press volume down and plug-in the charger it takes me to bootloader warning screen from where either it goes into charge or i press volume key and it goes into option which I again cant select cause power button is busted. Tried holding down the power button and connect to laptop(windows 10) no device detected and it works like normal charging. Tried to charge for a few minutes unpluged charger and start again .. it was stuck on oneplus screen. Any ideas??
