[Q] HTC One X not turning on

Yesterday my phone didn't manage to boot in Cyanogen mod 10.1, it showed the logo then froze..
After a while the screen went black, and the battery was nearly at 0% so i don't know the correct motivation for the turn off, if it was due to the reboot since cm wasn't loading or just no juice in the battery.
No it doesn't turn on no matter how many seconds I keep the switch on button.
Can't even get to bootloader or HTC white screen.
Connected to a PC it doesn't show up (neither as APC). The red light doesn't turn on.
I don't know if it is charging, but as it stay connected to the plug it became warm as if it were charging.
Said that it is no more under warranty (bought in China, now i'm in Italy) how would cost a repair? Is it convenient or just buy a Nexus 4 and say goodbye to my HTC?
Best regards!!

Connect your phone to a wall charger for a few hours and then hold down the Power Button + Volume Down button together until the bootloader shows up!
If you can go there, you can revive your HOX!
Repairing or buying a new N4 is completely your choice. If it is indeed a hardware fault and the motherboard needs to be replaced, it could be quite expensive!

LG G4 doesn't turn on anymore ( H818N)

Hi all,
My LG G4 doesn't turn on anymore even while I am charging it..
I am actually travelling, I suspect it does come from a high voltage when I tried to charge it in a bus.
At the beggining I tried to put the battery off the phone, first the screen with logo for few seconds and after black screen. Now only black screen.
When I try to charge it , nothing happens.
1st question : do you think that a hight voltage can break any other spare parts of the phone ? Do you think the battery can be a fusible ?
Where I am , I didn t find a LG selling point so I cannot try with another battery for now.
My phone is not under warranty anymore.
Do you think that this troube can be repaired in a common repair service center ? ( not LG )
Any advice except waiting to find another battery ?
Thank you guys !

The simplist thing to do is check if the battery is charged and working. Check the serial number on the back and reply with the first 3 digits here. It is likely that you have faulty phone that needs to be fixed by LG (if it is still in warranty)
If you're sure your phone isn't a faulty model, try to enter recovery mode.
1. Hold down the power and volume down button together.
2. If the LG logo appears, continue holding the volume down button but let go of the power button for 1 second. Then hold it again.
If you get to a recovery menu, there is hope.

Thank for your reply.
With my current battery (as I still didn't have the opportunity to try to change it) , I can't even power it on (no logo even while try to enter recovery mode)
I will try with a new battery and let you know !

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.

Help with 5x not booting/charging?

Having an odd issue with my wife's 5x (completely stock).
She brought it to me this morning - the phone wouldn't boot. She didn't think the batter was dead, but she wasn't sure.
I hooked it up to charge, left it for an hour. I notice now the charging indicator comes on screen for about 2 seconds, goes away, then returns a few seconds later, and repeats this.
If I try to boot it, I get the Google logo for a few seconds, then it shuts off.
I can hold volume down and power and get to fastboot, but I'm not sure what to do from here. If I choose recovery, I again get the Google logo for a second, then it shuts down.
Is it the battery? Something else? Any help is appreciated.
EDIT: I want to add, when I unplug it from a charger, I can't do anything - no even partial boot. I just don't think it's charging when it's on the charger because of the battery icon showing and disappearing in cycle. I suspect this is a power/battery issue but don't know what to do.

Do you have a spare USB C cable to try charging it at all?
It could be the cable so its never charging enough to stay on/boot. I assume all your chargers are the proper LG ones and no dodgy USB cable might have fried the phone in any way?
Otherwise contact whoever you need to for warranty repairs by the sound of it.

I think this is 5X problem , LG should take care of it .
This is not charger problem or anything else .
If you can go to download mode it should be fine .

Your phone just turns off or it reboots? If it's rebooting, same issue as mine and another user's phone.
It's probably the power button issue that's somehow always being pressed, making the phone reboots over and over. It happened a lot with nexus 5. I sent my phone to LG for a repair.

totally unresponsive G3, no bootloop, battery good - what next?

I've got a totally unresponsive G3 - it died on me unexpectedly. It had been a little "off" when I was setting it up - telling it to reboot sometimes required a VOLUME UP+DOWN+POWER to actually boot it up, had a tough time getting the LGFlashTool to work and ended up having to use imageprepGUI to achieve root/TWRP, had it trigger the "error: boot certification verify" trouble and had to walk it back with the Qualcomm drivers... anyhow, I finally got it all set up the way I wanted for one of my kids as a Christmas present and just after getting Lucky Patcher up and running (wiped the cache, installed a modded Google Play, etc) I asked my wife to charge it as it was on low power, around 10% or so. She plugged it in and...
Well, my son went to use it hours later and it was dead.
This thing is the deadest I've ever seen a phone. It doesn't respond to having a USB plugged in. I have two other LG G3s and swapped the batteries around - all of the batteries are charged and functional (including the one originally from the dead phone). It's the actual phone that appears dead. The LED doesn't respond to plugging in, there's no vibration on plugging it in, no combo of cables seem to work. Plugging it into a computer doesn't generate any response from my laptop or the phone.
I've brought phones and specifically LG G3s back from the underworld more than once, but this has me stumped. Any ideas? So far, Googling has offered up the following solutions:
1. Remove battery
Hold down power button 10s+ to drain phone entirely
Plug in battery
Allow to charge for 20min
Hold down power button for 10s+
2. Remove battery for extended period
Plug battery in
Turn phone on
I can tell you that method #1 doesn't work here. I'm about to try method #2... but I don't have a lot of hope.
Any other ideas?

I had that probleme 4 days ago, i fixed it by burning the internal memory with a Hair Drayer.
Don't burn the screen, you must burn only the emmc on the motherboard.
