[Q] Is my phone dead? Can someone please help me?

Hello everyone
I was using my phone and the battery was critically low and eventually the phone powered itself off. I tried recharging the phone later but I'm not getting the charging screen. I've pressed numerous keystrokes combinations (vol down + power, etc.) to start the phone, but the phone just wouldn't boot up.
I tried connecting the phone to the PC, and it's getting detected by Windows but it's showing the phone as 'Qualcomm HS-USB QDLoader 9008", and the phone's screen is still off.
Is there a way to revive my phone?
Thanks.

pull out ur battery, try charging with some other phone or external battery charger then try again
Already tried that. still no luck
Just keep it plugged to charger. It takes a while before it boots up again.
Tried that too. I plugged it in for more than 24 hours, but still nothing

fully charge ur battery in external charger than press volume up button then insert battery than insert usb cable which is plugged into a computer. see if downloading logo appear on screen. if yes then u r hell of a lucky person and flash a kdz. if nt then it is hard brick.
then u have to follow brick method which is available in forum. u v to search for it.
I had the same symptom as what you already described, regretfully and sorry but your phone is hard bricked, its not dead, just hard bricked. Sent for repair, it is cheaper than buying a new phone. trust me if you love your phone, it doesnt harm your money just for repair. But ask the repairer if it cheaper to just unbrick the phone because some repairer charge more for flashing the stock firmware after unbrick so basically
(jtag unbrick + flash stock firmware = $) then after the phone arrive and you can already access download mode then use the unbricking guide to restore firmware.

[Q] Xperia ION Turned off normally. Now no boot

Hey guys, was using my xperia ion and downloading some stuff and the battery was low and it turned off. I plugged it back into the charger the normal red light showed up. My power button is broken so i have to press the volume up key while i connect it to charger and phone thinks its connected to a computer in flashmode and boots up but this time it didn't boot up. I tried doing it again and again and nothing happened . Then i connected it again and no LED was there. Since then i'm trying to put it to charge.LED is not turning on and neither is the phone turning on. I don't know what happened. Can u help me ?
My phone was on Stock 4.1.2 and was rooted without a recovery and was working absolutely fine before it turned off. Please help i really need the phone up soon it had my projects and yeah one more thing. When i connect my phone as it is it shows SEMC flash device in Device manager without pressing any button. What do i do now ?

Please charge the phone overnight (in power off mode - remove the battery for 2 mins, put back the battery, do not turn the phone on). Then try to revert back to Stock ROM in download mode...

G3 Will not charge or turn on

i have tried to hold power and vol down and nothing happens too. i have already bought a new battery and tried that but that didnt work as well as tried using other chargers etc. nothing seems to work.. please help!
any suggestions??
by the way i am running cm13 on the phone, don't know if that might change anything.
Do you get anything when you plug it into the computer and try turn it on?
Can you put the phone into download mode at least?

Htc one m8 Orange led flashing ,No booting, No charging ,Not recognized on pc

Hello Recently i purchased an Htc one m8 from ebay and i cannot get it to charge or power up ..
When Connected on wall charge with different cables it gives a some minutes flashing from the upper orange Led and that's it.
When connect through Pc its not recognized only the qualcomm driver is shown on the devices but i cannot do nothing.
I've tried recalibrating the battery it doesnt seem to work.
I did the Power + Vol up and Vol Down combinations it doesnt seem to work either.
I changed the charging port with a working one its the same.
Next step i will go with a new battery but before that i want check if its software problem because im lazy change the battery if i dont have to.
Ps. there is a possibility the phone is bricked
Does someone know or have the patient to explain how to flash a stock rom or something like that
