Phone Bootloops. New to HTC.

Hi Guys,
One of my friends HCT one X is just going into bootloop. she has no idea what happened. She tried to upgrade the OS (via OTA) and probably slept. So i suspect that the update did not complete properly and this is causing it.
I havent used HTC once, so i have no idea what S-off, on. Fastboot etc is.
I managed to go to the recovery mode (power +vol down) and see that
S-On
Hboot-0.96.0000
eMMC Bootmode-Disabled
CPU-Bootmode - Disabled
WW Secure Boot - Enabled
Can some one please let me know how to fix this issue.
Thanks

You need to download the android sdk bundle, extract it and navigate to the platform tools folder. Open a command window there.
Put the phone in the bootloader by holding the power button and the volume - button together as long as it takes to see the bootloader.
Then connect it to the pc and type this in the command window
Fastboot getvar version-main
A number should come out.
And if you have HTC syncmanager installed ? Uninstall it but leave the drivers on the pc

OKay..this just went past my head. By SDK you mean HTC's SDK which is here - http://www.htcdev.com/devcenter/opensense-sdk or the Android SDK

I have the android sdk. I know that works

[Q] Please help me unlock my HTC desire 816w bootloader

Hello Guys..
A few days ago I have bought a Chinese HTC desire 816w, it comes with sense 5.5 so I decided to flash a new rom for it, but I'm stuck in unlocking the bootloader, I'm following the steps provided in htcdev.com and everything was fine till I reached the command "fastboot oem get_identifier_token" and when I write this command and press enter only this message appears ... (the three dots are the response from CMD) and after that nothing happens and cmd doesn't allow me to write anything more, please help, me I can't live with a locked bootloader.
Note: I have installed all the correct drivers and I have Google SDK and i use windows 8.1 (and tried once on windows 7) so I guess everything seem to be fine I don't know what's the problem
Note 2: when I try to go to Hboot (volume down+power) I get a totally different screen from the one supposed to appear and it is written in Chinese.
Guys Please hep me I have spent the last 2 days trying to figure this out.
Thank you so much

When on XDA I assume you selected "HTC One" as the model? Also, you have the fastboot command line open but when you go to the bootloader are you presented with two options that the volume keys can move on or are there more than two with each selection a different color?
When you enter the bootloader;
- your in hboot mode
- pressing the power button once will enter fastboot
- then you run the get token command
- get the code
- send it to htcdev
- get the file from email
- drop it in the adb folder " platform-tools "
- run the command to flash it then type " adb reboot fastboot " or press volume down 3 times and press power button.
If the bootloader has two options only on the main screen it should be either "fastboot / recovery" listed or "yes / no".
This should work, let me know how it goes.
If possible take a picture of your bootloader screen.
Also, if it says " Uboot"; its a fake HTC device.

The thing is, that when I'm trying to get into the bootloader by the official way (Power + vol down) I get a different screen from the "supoosed to be" Hboot screen it's written in chinese in other words, it's not the Hboot screen I saw on many tutorials, I have translated what is written on the chinese "hboot screen" and it appears to be a page to test if the components of the device are working properly and this is the only page I get from pressing vol down+ power,so I couldn't do anything but to enter the fastboot mode by the ADB command "ADB reboot bootloader" and only after that i get into the fastboot mode, but I got the same error while trying to get the identifier token..
I have attached a photo for the "chinese hboot" screen that appears when I press (vol down+power) and a photo for the error I get when I try to get the identifier token
I guess my device is either fake (hope not) or modified.. if it is modified is there anyway to install the HTC Hboot on it?
Thank you

The only thing I can recommend to you is that you try adb reboot fastboot and to make sure that fastboot is unchecked in the options of the device. If you cannot access the code after these options then I'm afraid to say your device is fake. Not only that but due to current limitations on this specific device, there is no way to flash a completely different bootloader. Besides; as for HTC - all are the same/similar in layout, just language modified.
You could try to click each one of those options and hopefully you'll come across the bootloader. You never know maybe that's just an extra menu; although, I highly doubt it.
Sorry

Did you solve the problem? I just bought a htc 816w and have the same problem now.

From looking at that second screen shot, it looks like the recovery, not fastboot. Fastboot should have a white background(at least it does on mine), while recovery has the dark background. Also, fastboot should have some info at the top of the screen and commands close to the middle, while recovery only at the top of the screen. Try the advice given above, go to settings-power and make sure Fast Boot is unchecked. Go to About in Settings, then Software Information, select More and tap on Build number until Devloper Options are enabled. In Developer Options, check the USB Debugging option. Now plug it into your PC and try the command
adb reboot bootloader
That should get you into fastboot. Then you can contnue with unlock commands.

Was there any solution for this problem?

Try to open Fastboot with adb commands.
First of all, make sure USB-Debugging is enabled on your device and all drivers are up-to-date (HTC Sync, Java and fastboot).
- Download ADB fastboot folder (just extract it to C:\ and you're good to go)
- Connect your device and PC using usb data cable
- Navigate to ADB folder and click on any free space while holding the shift Key
- Choose 'Open command window' here
- Once cmd is started use this command
Code:
fastboot devices
and check if your device is listed, then type
Code:
adb reboot fastboot
to reboot your device. It should start in fastboot mode.

i have same problem!
i fund that beacus my device is based MTK cpu dont have fastboot & bootloader!
are you find any solution for this problem?!

Take a look here.

Bricked, completely noob in HTC, need some help for a friend.

I'm not a HTC user myself, but my friend got his 816 on bootloop, and if he hold the power + vol- button in boot he will get the android robot screen, but not the menu which is supposed to come.
Sorry I'm a sony user and i'm not familiar with htc, the phone is not even on my hand but i'm just trying to flash the stock firmware again. Could someone give me a simplest possible guide，maybe something like flashtool on xperia.
And how do i completely shut down a HTC phone? it keeps rebooting itself with power and vol+
Thanks

First of all, to help, we'll need to know more specs of the phone..
If your in a bootloop, try holding vol +, vol - and power at the same time, once the screen is completely black, hold vol- and power. If you're doing it right, your device should boot in the boatloader. White background, phone specs at the top.
Please post this data, since we'll need to know the device model to help.
If this doesn't work, try to use adb commands.
First of all, make sure USB-Debugging is enabled on your device and all drivers are up-to-date (HTC Sync, Java and fastboot).
- Download ADB fastboot folder (just extract it to C:\ and you're good to go)

- Once cmd is started use this command
Code:
fastboot devices
and check if your device is listed, then type
Code:
adb reboot fastboot
to reboot your device. It should start in fastboot mode.
And if that doesn't work either, try using
Code:
fastboot getvar all
instead of
Code:
adb reboot fastboot
and post the result.
