[Q] HTC One won't turn on - One (M7) Q&A, Help & Troubleshooting

Hi guys,
I just got my HTC One this morning, and I was trying to root it.
Since I'm very stupid, I didn't read the whole guide before starting, and I tried to get into bootloader mode without unlocking it first.
At first the phone was stuck in QHSUSB_DLOAD (blank screen, but the computer saw it as QHSUSB_DLOAD)
I used this tool to get out of it : http://unlimited.io/qhsusbdload.htm
Now the phone won't turn on at all, it is not seen by the computer, and pushing the "on" button does not do anything.
The only sign of life that I have is that there is a red led shining in the speaker grill.
Can anyone help me?

I had another stupid idea: I have a USB JIG, dating back to my galaxy S2 flashing days. I decided to plug it in... And it actually worked!
My One has rebooted into android.
I'll root it when I have read everything there is to read 24 times

have a look at this might help

[Q] Completely bricked. No orange light, can't turn on, PC won't detect it!

Hey guys,
Yesterday I ran RUU to update my phone. After it finished upgrading, I haven't been able to turn it on. My phone has S-OFF and had recovery on it.
i've tried going into recovery (via volume down + power), and have not been able to get into the hboot menu. I've taken off the battery, etc. tried a lot of things, but the phone just will not turn on.
I searched, and some people mentioned the SLCD problem, but the thing is that my phone isn't even recognized.
Any help here plz!
Ed
Also, when I say it doesn't turn on, I don't mean by bootlooping at HTC screen. i mean that the computer is like 100% dead, screen doesn't turn on, no nothing. PC doesn't detect it. I've also tried making it go into HBOOT thinking it's SLCD problem, and seeing if my PC can detect it...but it can't
I have read in other forums that leaving it for a few hours may help
As in leaving it overnight, and coming back to it the next morning
Maybe leave the battery out for a few hours, see if it helps
Not saying it will definitely work, just a suggestion
Could this be what happened?

[Q] HTC ONE no power or led

Hi, I posted a question on this already but the situation has changed. So firstly what happened was i rooted, flashed cwm recovery and was running the sinless rom GPE. this was fine for about a month and then i decided to s-off...the s-off process went smoothly and the phone powered back on like normal. Then i flashed another rom and there was a cyan colour filling the screen at boot so I decided to restore from a previous backup. However this backup was done before the s-off process. After restoring successfully I clicked "reboot phone" on CWM and since that the phone never turned on or show any signs of life.
At first it would connect to the computer but show up in device manager as QHSUSB_DLOAD but now when I connect the phone to the computer it jus disconnects and reconnects over and over.
Things I tried:
Holding power button for over 2 minutes (with and without bright light on the sensor).
Left charging for over 4 days.
Holding Power+VOL down for over 2 minutes.
Holding Power+VOL up for over 2 minutes.
Holding all three hardware buttons for over 2 minutes.
In the process of trying all these things not once did the led even blink or did the phone even show any signs of life. Can anyone help with this situation?

Hi mate, as i know, the QHSUSB_DLOAD mode, is the same to say: bricked phone...
So, probably, you have to send it to htc for warranty and they have to change your motherboard...

I was hoping that wasn't the case..but oh well...would they be able to know if I was s-off or anything?

Theoretically no, because the mainboard won't work...
I think is the possibility that your phone is bricked is hard
HTC One, Froze, Restart, Cannot turn on, NO LED etc.

I also had the case of my HTC One, my battery was still at 55% while I was watching a video until it froze, so I decided to shut it down to reboot but when I tried to switch it on, it already does not show the Red LED, did any possible combinations of power on and pressing down the volume also under bright light, but there's no luck on it. However, I tried plugging my phone to the PC and there are still the sounds that it has connected. I checked it on the devmgmt.msc but it says that:
Base System Device, QHSUSB_DLOAD and Unidentified Device - All appeared to say "No Driver Found"
It has been a day since I left my phone wall charged, plugged it in the PC with the USB detected sounds but still can't turn it on. Is there any other way to turn on the phone again? Since I badly wanted to recover all my photos and other stuff from the phone Any possible help/tip/advice would be much appreciated! Would there be any way before sending it to the HTC Company? Thank you in advance!
There is a possible fix for that around here somewhere, a Guide to fix hard bricks, typical I cant find it now.
EDIT: Here it is, only supports M7_UL devices though, never had to use it so I cant answer any further queries on it, if you have any problems trying it you'll have to post in that thread.

Galaxy Tab 10.1wifi is going to be thrown out the window !

Ok so this will be my second post, no one replied to my first.
Will try to explain what the problem is. in as much detail as I can.
Please help me out guys !
So, tab was in debug mode, messed up using odin, trying to root, not sure what went wrong there and gave up.
Rest of the day tab worked fine.
During the night it was not turned off but left on charger, icon showing.
I listen to audio book while falling asleep
When I woke up, pressed on and nothing, black screen
Panic and frustration followed.
New charge cable, black screen
Searched internet, did the button combo's , took back off, disconnected battery, drained battery, still black screen.
Disconnected all cables inside, reconnected, black screen
Conncted to win7 pc, by holding down power and vol down, pc sees unknown device in APX mode.
Installed various drivers, all I could find that might work, installed and seen in device manager.
Followed nvflash guides, get an error usb write failed.
List devices command, nothing appears.
Installed Samsung Kies. cant connect , using different drivers also.
Odin cant see the device either. Pdanet installed, same outcome.
Also the sdk route, always no device found
I havent got new battery yet, cant afford one at the moment.
With everything I tried it always comes down to device not being seen even though it does appear in device manager.
Installed usbdevieuw software , check the properties, it does say 0mA , which is different to when I check my usb keyboard or mouse, they do have power 90mA etc. which is weird.
I have read and tried just about everything concerning my specific device. I am stuck.
No idea what to try next.
I understood that apx = download mode., which would be fine if I could see something on the tab screen. I know that normally when into download mode you have to use vol up to cross over to the right icon.
So, power + vol down... wait till its in device manager on pc, then vol up. Tried this, seeing as the screen is black I just waited a bit and then vol up, guess work actually.
Anyway, if someone has any ideas etc please let me know.
Thank You All

Thank you !! for responding. I did as you suggested, Its cool software.
that being said, no matter what option I choose I get The system cannot find the path specified. To me that means that the tablet cannot be entered even though it does show up in device manager samsung android phone> android adb interface.
I mailed samsung help desk and got a reply saying, take it to your nearest samsung repair store. .. THEY can fix it......as I expected they would say.
Im still wondering if the battery is causing the problems. As screen is black, when on charger stays black.
However if the tab is seen on my pc, does this mean tab has power?????
I have no idea how to test the battery without replacing it.
Im guessing tab is fully bricked and if so would that explain the no battery charging icon??? and lack of any other screens lol :laugh:
Anyway, I have learnt so much from reading this forum. I admire the great work and assistence provided.
Guess my tab problem is either too easy to provide a fix for or hardly no one has a clue how to fix my tab :silly:
Please respond and help me out!!!

i8200 all working but black screen

Sorry guys if this mentioned before but my dad brought his i8200 to me last night saying phone went to a black screen a while ago. Let me explain the situation;
Phone boots up, works, if I put my sim card on it, I can call myself however during this whole time phone screen is black and unresponsive.
I tried to flashing official firmware via odin which didnt help. I dont know if it is related but when I connect phone via usb cable to pc I see it is popping up in "my computer" tab but I cant look into it because it is locked. However at the same time odin recognizes the phone which seem odd to me. Any help would make my old pal happy.
I know it is a fairly late reply, but have you tried opening the phone up to check the connector and cable going to the screen?
I am in a similar position, but our S3mini is even less alive. So I just opened it up today. I used this site with the remark that the speaker (the one that is against your ear when making a call) is held by stickytape so needs very careful prying loose to prevent the flatcable from being damaged.

T-Mobile G Flex only charging (D959)

Hi Everyone,
I was hoping someone would be able to help me with this as I've been at it for hours and I still can't do anything.
Basically at this point I think my phone is stuck in a reboot, what happens is when I open the phone the LG logo pops up, after that the T-Mobile 4G LTE screen with the white background shows up and the phone basically either gets stuck on that screen until the charging is finished or reboots every hour or so. I don't understand whats going on I've never touched the phones files and I've never rooted etc. I've also tried to hard reset but its the same problem. I found a ROM for this phone (original from TMobile) and I was planning on trying to install that and hopefully getting it to work but for that I need to be able to get into download mode, whenever I hold the volume up button and plug the cable in it goes straight to charging and my laptop says USB Charge only Interface (tried all 4 ports), I've also installed the LG United Mobile Driver but to no avail. Since my laptop is not recognizing that my phone is plugged in other than a simple sound and the laptop charging the phone I don't know how else I can get the phone to work because I cant access developer options either for the phone because of the reboot / stuck problem.
Does ANYONE have a fix for the problem? I don't want to go out and buy another phone because I really like this phone. I hope there's a fix. Thank you.
Ive come back to this issue and I still haven't found a solution, I'd be forever grateful if anyone has!
