[Q] my htc one x in apx mode help ??

hello
i have htc one x (unlocked and rooted) i manage to install cyanogenmod and it worked
while my phone is working i press power + plus down in order to reach bootloader mode the phone screen goes black and it refuses to boot
and refuses to charge -- i tried a lot of combinations but not useful
when i connect it to pc it recognize it as apx mode then unknown device
i installed driver for apx mode and it reecognize it as nvidia usb boot recovery driver for mobile devices
i tried to use nvflash but no manual on how to flash boot available in the net
so any suggestions or help
thanks
Hmm well APX means usually a hardware fault (brick) most posts about APX and its solution are temporary !
Sorry.....getting the mainboard replaced is the best option.
since we have no htc in our country can I replace the main board
Well sure if you have the knowledge and nerves to do it.

HTC One X doesn´t start anymore

Hello guys,
I am new here and thats my first post, please tell me when I do something wrong. But I think this is the best forum to ask :
I had a well-functioning HTC One X. But at once it doesn´t start and stuck in the HTC bootlogo. I googled it and after many days I try to unlock the bootloader. The bootloader starts only after many trys and then shows a red field "battery level is too low to flash"(connected to PC). The red led doesn´t lights up. I leave it in the bootloader and after many hours it starts normally (bootloader still locked). I set the phone back to factory settings (not in the bootloader). I used it like every day, but after hours when I switch to the normal menü it was stucked for 5 seconds and then the screen become black and it wont restart. I buy accumulator for the phone and exchange it (I have a little bit "hardware skills"). I connected it with loading cable to the socket (not the PC!). The red LED flashes for a second and then happens nothing. After many trys the bootloader shows up (connected to my PC) and I googled for almost hours to find a solution. "I have to install a custom ROM". I unlocked the bootloader with the programm "One X All-In-One Kit v2.3". I don´t know why but I shut the phone down. I try to start the phone or the bootloader but it doesn´t work. I try it now for weeks but it is dead (but I´m very sure the problem that it doesn´t starts is not due to the unlocked bootloader, because it is the same problem with the "not starting" like the time before I unlocked it). But the strange thing is... and now comes the important part... when I connect the phone with my PC the PC make the "USB connected"-sound and says that there is a unrecognized device connected. And when I try to start the bootloader the PC makes the "USB disconnected"-sound and a second later the "device-driver software not installed"-sound (I hope you know what I mean) and when I keep trying to start the bootloader it happens again and again the same. I tried almost everything, I use a loading.bat file but it can´t detect the phone (you know "unrecognized device"). Is it the accumulator ? Is the hardware dead ? Or what is the problem ?
I hope you understand this text (I´m sixteen and from germany). If you don´t please ask me every question you have. I really hope you can help me with my really long-term problem.
Thanks for every question, reply, solution or improvement proposal for me

So, what i have deduced is that
1. You are stuck on fastboot with low battery.
2. Your PC does not recognize your device.
For this purpose, first download and install the htc usb drivers. These should work: http://forum.xda-developers.com/showthread.php?t=2211791
Then visit this thread: http://forum.xda-developers.com/showthread.php?t=1658084
follow the instructions, once your phone is charged enough, unlock the bootloader, flash a custom recovery, boot into recovery and let it charge for a while, then flash a new rom.
Dont forget to press the Thanks button if i helped
Okay thanks for your proposal, but the problem is now that I can´t boot into bootloader, the phone does nothing. No reaction, no charging LED, no normal boot, no bootloader...absolutely nothing. Only when I connect the HTC to the PC the PC make the "USB-device connected" sound, as if you connect a USB-stick to your PC, but nothing else happens.
Any ideas or similar problems ?

So try to charge via pc. Leave for some time connected to pc and try to power up.
Hey,
I tried it, but it didn´t work. Nothing happens, only the "plug off-sound" when I want to start the bootloader via volume down+power button, while it is connected to the PC. I have no idea what to do.

[Q] One x crashed after OTA Update, Dead?

Hello.
I have HTC ONE X for a long time.
today i suddenly got a notification for update (as far as i remember it was the"heartbleed fix" update).
ive downloaded the update and start the installation.
at the moment i press start the phone turned off and became like a "zombie".
hes not turning on, doesnt show the red led while charging (and also doesnt heat up while charging like it used to).
i tried to connect the phone to my pc but pc doesn't recognize the device, and the phone doen't respond to the connection.
some details on the phone (if you need it): CID_044, the rom was official, official recovery and boot, it was relocked because i did it withot changing anything except the unluck and relock.
i tried to download drivers and re installing them, as well as java.
tried to press power +volume up\down\both.
tried to search for device using adb.
tried to rebbot via fastboot and adb (throught the pc).
all this without any luck.
anyone got anothe suggestions? the phone i completly dead?

HTC 10 unable to flash etc..

Hi All,
My Dad has given me has HTC 10 has the battery drain is crazy, when look at the phone the capacitives back and recent apps were not working only the menu button.
i checked the settings and nothing out of the blue why this was happening, so the first thing i did was factory reset the phone, this didnt resolve the issue.
So i though i would reflash the RUU on his phone but the phone will only show has slow charge on my Windows pc, laptop and chromebook, i cant get it to to pick up in ADB etc...
I also hard reset it too in the boot menu (again even if i load in to boot loader the phone isnt detected ) I have over 10 usb c cables (and these work fine on my HTC U11 and allows mew to go in to debug mode etc.. on that phone)
does anyone know what to do so i can flash it to an old version, his CID is H3G__.001 but i cant find the RUU for this only the HTC__.001 and this fails with incorrect footer etc.. i just also tried installing the update via the sd card and getting the same errors.
regars
Scott
The Capacitive buttons and the charge port are part of the same board. You could have an issue with that board. If the phone isn't rooted, to allow adb over Wi-Fi, you might be out of luck.
