[Q] One x touch screen fail

Searched many places for my problem but cannot find it specifically and this forum seems to be more clued up than most so here goes.
One x screen started to occasionally freeze on unlock screen (volume buttons worked also the volume pop up came on so screen itself not frozen just couldnt touch input i presume) but would fix with either a full power down or a few presses of the top button. Over the course of a day or two this has progressed to virtually always freezing and finally to where i couldnt unfreeze it even after powering down.
Did a factory reset which did give me access to my phone again but still the problem persists.
From my research it could possibly be some sort of cache problem. Also noticed after factory reset with no apps or data installed, apart from the preinstalled ones, am using 4.7 gb of internal memory with only htc sense running. this seems excessive to me but never checked it before so not sure if this is about right. If not then the cache theory could be right.
So can anyone help me please.

Try following this:

No need to root / unlock bootloader
EDIT: follow option 2

following option 2 but stuck.
Make sure that USB debugging is enabled (Settings/Developer options). In order to determine which ruu file you require, boot your device into bootloader mode (Power off and then restart device by holding Power and Volume Down button together). Connect to pc via USB and check that device shows FASTBOOT USB on screen. Enter the following command in command prompt:
fastboot getvar version-main
But when i enter that in Command prompt i get fastboot is not recognised command etc using windows 8. Any help
Note: my phone is locked

Can you try running fastboot on a different OS? Windows XP/7, Ubuntu? Something else?
EDIT: BTW, are you sure you are running the fastboot command from the fastboot folder?

Navigate on your PC to the fastboot folder lets say "c:\fastboot".
Shift+right click on any blank place and choose open command window here(or something like that my OS is not in english now).
Try using fastboot commands .

Sorry,

If after running RUU nothing changes take the phone to service.

more problems
Ran and installed the ruu but got an
error[152]:image update error
The ROM update utility cannot update your android phone.
Please get the correct ROM update utility and try again
But i have the correct version already 3.14.401.31 it just wont install and now my phone is stuck on a black screen with htc in centre and nothing else.

Did you run the ruu.exe as a administrator ?
Right click the ruu exe and select that.....and put the phone in the bootloader/fastboot usb mode

Hold the power button and the volume - button together until it reboots and boots into the bootloader, hook the usb cable and you should see "fastboot usb" in red text. At that point you run the ruu with administrator rights

Try shutting of the phone, powering on when holding power button+volume down for about 8s.
You will get a hboot, choose fastboot connect usb cable and try ruu with admin permissions

finally did get to hboot screen by letting the phone shutdown itself but couldnt ruu as battery power to low so i powered down and recharged battery but back to square one where i cannot get to boot screen just constant black htc screen and cant power down again.
So ill let my battery run down again to power off completely open boot screen then stay on that til i power up enough to try ruu again.
Il let you know what happens when this is done later.

Urgent - Boot and recovery problem!

Hi to all
I have a big problem. My HTC Desire HD is now "dead". So, everything is working normally, just fine, on JellyTime, but this afternoon everything get broken. Suddenly, after the boot animation is finished, nothing happens, the screen is "black". The phone works, because when I connect USB to the computer sound. I can not get into Recovery (Home + Volume Down), can not do anything. I tried to remove the battery, but it does not help. I tried with adb, but there is "error: device not found". So I installed the drivers, asking me activate USB Debugging on the phone, and I can not access the phone.
Do you have any idea how to access recovery mode and install the new ROM?
Please help!
Thanks in advance.

just turn on your device with press volume down + power to get into the bootloader..then from there you can select recovery

No, I can't go to bootloader with volume down+power. About state of phone... S-off, that's I know. The ROM is installed earlier, but today I perform full wipe, and then installed ROM again, not backup/recovery, but fresh install. USB debugging is, as far I know, disabled... What should I do?

i assume that you already had SDK/ADT or adb.exe and fastboot.exe on your PC.. if not just downloading from here..
and already had installing the latest HTC driver on your PC..
firstly your let the phone is boot like normal..then after you see the black screen..try connecting it to your pc..
then open your SDK folder (place of adb and fastboot.exe) then run cmd and source to your adb folder.. example : if your adb folder is in "C:/android tools/" then you must change source to that folder with typing "cd C:\android tools", now you ready to used it..don't closed it..just let it open
while your phone already booting n had black screen..then already connecting it to usb on your pc..then firstly try typing "adb devices" to check that's the phone is already connected with adb..
if your phone is detected..then you had prompt after that is your phone serial number that on list of attached devices
if success connected..then you can typing "adb reboot-bootloader" or "adb reboot recovery" (all command w/o quote)

you sure that your pc already had latest HTC driver right and support with your OS..?
if so..maybe that's the usb debugging is not already active on your phone indeed..
because what i know is that just had two option to access your phone again:
1. with your volume down+power to access bootloader of your phone..and you can do it everything from there..
2. with adb command on android home of your phone..
while both option that is doesn't work..i'm sorry..i don't know more how the way to access your bootloader again beside the two way above..
anyway maybe you can try it again like the first way you success go into bootloader with pull out the battery over few hours like before..
and when you've already success flashing new rom again..don't forget firstly to enable it usb debugging from system settings..and connect as charge mode only..
and don't forget to disable fast boot mode too from system settings if you using sense rom

Yes, I have valid drivers, because before this disaster it was possible to connect phone with PC without any problems.
Have you any idea why the phone go "dead" after few hours working just perfect? Hardware or ROM related issue, what do you think?
I pulled battery out just now, for tommorow morning I giving up, maybe I'll be lucky and again I can with volume down + power booting into Recovery Mode.
Thank you, my friend!
P.S. Do you have any suggestion for some stable and good ROM?

i'm not sure about that..until now..what i see is still software related..but i don't know what software exactly had the problem is..
can be from the recovery that you had installed the rom..or else..
to make sure what exactly is.. you must return the phone to the stock..stock bootloader, stock rom and stock recovery too..all back to the stock..with flashing stock RUU while your phone back in normal condition..
you know the forum rule is doesn't give any permission to all member for compare the rom..

[Q] I can't access Bootloader or Recovery PLEASE Help!

My HTC One M8 (Verizon) is seemingly bricked. My phone is rooted, S-Off, with the stock ROM. I have been trying to update to the latest OTA update by returning to stock. I had previously modified some entries in the Build.prop and Platform.xml. I knew those had to be default in order for the OTA to work. I had copied the original files and pasted them to my SD Card so that I could simply cut the modified versions, paste them to my SD Card, and cut the originals from my SD Card and put them in their corresponding system folders.
Upon a reboot something apparently went horribly wrong because all my phone does now is boot with the white screen and green HTC Logo, then the screen goes black. I have tried the typical Power Button + Volume Down but it won't enter the boot loader. The good news is that the USB port seems to still work for my windows computer recognizes a device connecting to it but it doesn't show up as an interactive device in windows explorer..if that makes sense.
Please Help!

When you connect it to the PC can you pick up the device with adb? If so, have you tried to run the command from adb to boot it into bootloader? adb devices ... if found, adb reboot bootloader

I'm not too familiar with ADB commands but I typed in "adb reboot recovery" and it said: "error: device not found" so even if my command was wrong it's still not detecting it. I also tried: "fastboot reboot bootloader" and it just says "waiting for device"
Also I feel like it's worth mentioning the phone is automatically rebooting every two minutes or so (haven't timed it exactly but it's a while). Still showing the green HTC Logo then the screen goes dim, then the screen turns off.

Try holding volume UP + Power button, this simulates a "battery pull", just hold it in for a while it can take a while to "pull", when it's off try again booting into bootloader, volume DOWN + Power button.

I held Volume Up + Power Button and it showed the white screen with the green HTC logo. I then released all buttons. Once the screen turned off I then held Volume Down + Power Button for two minutes straight and nothing happened.
Even though we haven't found a solution yet, I am appreciative of the help.

sounds like you never installed the htc drivers for your phone, hence your pc doesn't see the phone when you are doing ADB commands.
install the drivers for it, then try the ADB commands via your pc
and dont mess with the build prop or other system files unless you have a working back up and are 101% certain about what you are doing..

Just remember to change directory in command prompt to the folder where adb.exe is located.
I don't know why the device doesn't reboot into bootloader though when you hold volume down + power button, shouldn't have to hold it for 2minutes. Holding volume up + power button to simulate a "pull" should only take up to 20 seconds or so at most and pressing volume down + power will then immediately take you into bootloader mode, or at least it's supposed to.
Did you release the volume up / power combo when the screen went dead or before? Try holding it until the phone shuts off and then right away press volume down + power.
Sorry if I'm not answering right away though, busy eating, and will be here and away for the next hour or so while I get ready for work =o( once I leave for work I'll only be able to help some more after like 2 hours or so. Hopefully we can do something before then though =o)

You're right, I didn't install the drivers. I did so and ADB was able to recognize it and I was able to access the bootloader. Thank you everyone for your help. I won't be making the mistake again.

So you'll be able to fix it from here on then? I was just about to link this thread to you as well should you have gotten adb to work again, it's for the RUU for Verizon seeing as you said you're on Verizon.
But going by your response up there you might already know how to fix this issue further :good:

Share another method of getting into recovery mode on non-responsive blank screen
Hi,
I just want to share how I accessed recovery mode with the same build.prop issue but with S-ON (might work with S-Off too).
I found the solution from here:
http://forum.xda-developers.com/htc...ter-download-mode-t2853100/page2#post62490577
To get into recovery mode on a non-responsive blank screen, hold the power button and volume up button at the same time and then approximately after 10 seconds, switch from pressing the volume up to volume down button before the HTC logo white screen shows while still holding down the power button. After, a white boot screen will give an option to go into recovery mode.

Question Download mode issue

Hi everyone. Ive got my first samsung smartphone. I followed guides to get root, but unfortunately I had no oem unlock button in settings, I used date tweak, and button appeared, until I closed settings window. However in download mode, I still dont have any option to unlock bootloader, only use vol+ to enter download mode, or vol- to reboot. I ve tried to unlock it from adb, but no luck I just get my phone restart while trying to acces fast boot with adb reboot bootloader. Please help, phone is cool, and I dont want to refund

If the oem unlock isn't in the settings app you can't root it.

Go to Download mode like this :
Turn off the phone
Hold volume + and - and then plug in a USB cable ( already connected to a PC )
Then you should see that "unlock bootloader" option

Bootloading Kyocera DuraXV Extreme

Hello, I'm having some serious trouble bootloading my Kyocera DuraXV Extreme (AOSP)
I've went into developer options and activated USB debugging and allowed OEM unlocking.
But I get stuck on rebooting into bootloader mode. I've tried different approaches:
1. Starting up phone while holding volume up and down buttons. Then select "reboot to bootloader".
2. adb reboot bootloader command
Both options reboot the phone without going into bootloader mode.
Seems Kyocera decided to somehow lock the bootloader mode. Anyone know of a workaround here?

My comments below are based on the belief that you are trying to unlock the bootloader.
I am not familiar with this phone but generally the two steps mentioned by you are not enough to unlock the bootloader. After those steps, you'll have to issue a command via adb to unlock the bootloader and if successful, then you can boot into it for further operations. The command will vary between devices, so search and profit.

Thanks, this cleared it up a bit, you are right, I'm trying to unlock it.
I'm trying the command fastboot flashing unlock but only getting the message < waiting for any device >. I read somewhere that I might need some USB drivers but I don't know where to find them. I have the latest version of the standard USB drivers for the phone, but as I understand it I need special drivers for this?

I'm trying to follow the steps here: https://www.ifixit.com/Guide/How+to+unlock+the+bootloader+of+an+Android+Phone/152629#s317298
I get stuck on the step:
Enter the command adb reboot bootloader
Wait a couple seconds until your device rebooted into the bootloader, then enter the command fastboot flashing unlock
My phone isn't "rebooted into the bootloader", it just reboots. It gives the message "< waiting for any device >" when I write fastboot flashing unlock

My phone isn't "rebooted into the bootloader", it just reboots. It gives the message "< waiting for any device >" when I write fastboot flashing unlock

It should be a driver issue. When the phone is on and you connect it to the PC/laptop and send the command 'adb devices', does it show an alphanumeric value? Likewise, when you are booted into the bootloader by key combination and send the command, 'fastboot devices', does it show the same alphanumeric response? If so, the drivers are installed properly. If not, either you don't have the correct drivers or they are not installed properly. Try installing the drivers again after disabling driver signing in Windows on your PC (search for it on Google).

Hello, can you clarify what you mean by "booted into the bootloader by key combination"?
My problem is I cannot boot into bootloader at all.
Any attempt at doing so results in a normal boot of the device.

Are you sure that the key combination for booting into bootloader is what you described in the first post?
1. Starting up phone while holding volume up and down buttons. Then select "reboot to bootloader".

I see Power plus Volume Up as the suggested one from a Google search. Try that.
If you can't even boot into the bootloader with the correct key combination, I don't know how to help you further since we are starting to go in circles. I am sorry.

Hello, thank you so much for trying to help me. It seems I can't boot into bootloader. Volume up + power gives the same result as what I did before.: It opens a "Recovery" menu where I can choose reboot to bootloader, but this option just reboots the phone.
I've been in contact with Kyocera and they say:
Thanks for contacting the Kyocera Customer Support. We will be more than happy to assist you with your concern
In this case allow us to inform you that since this device is a basic phone , it doesn't have the option to activate fastboot mode. By installing something that will change the way the phone works , that will void the warranty that came with the phone. We as manufacture can not help you to modify the software that came with the phone.
So the phone's fastboot mode has been deactivated. But since it's an android I guess it should still be possible with some workaround. I just don't know whee to start, I've been researching for a week with no result.

Something interesting ehre, maybe someone with more coding knowledge can tell what's going on.
I found the source code for the phone and located a file called recovery.c which I guess handles the menu I see when I press volume up + power button. Maybe some clue to why the phone isn't going into fastboot mode?
