You have to hold volume down button when booting.

Argh.......my fault. USB C was not connected. Case closed.

Read my first post. You don't have to hold the button if using adb.

[Q] Totaly bricked?

@alray
i did search arround, but haven't found nothing similar with my problem..
i able to recover a phone if i cannot enter in fastboot or recovery. in bootloader it works but it freezing in the moment i push power button to choose fastboot or recovery. also it doesn't boot normal-> it's starting, showing the "htc powered by android" screen then goes off.
mention: in the bootloader is no "Active CMDline overflow" message.
only thing i'm interested if it's possible recover from this.

if you're S-Off and it doesn't work then you need to downgrade hboot first. if you are S-On and it doesn't work, then
stuck at 1st step.. "fastboot devices", nothing listed.
i have drivers instaled, also the Universal Adb Driver. what am i missing? if i try the to flash anyway the recovery it says <wait for device>

it's in bootloader where i have to choose between
fastboot
recovery
factory reset
...etc
and here, if i choose any of above it is freezing, with the option i choosed highlighted. that's all

i can select fastboot, but when i press power button, the bootloader freeze. it does not enter in FASTBOOT USB.neighter in recovery or any of the options of the bootloader. it's freezing with the option highlited after i press power button. after the freeze, only thing i can do is to keep power button+volume down, to restart to bootloader, where again, if i choose any of the options, it freeze again. also doesn't boot in normal mode, it's just showing the "HTC powered by android" then goes off.

what hboot are you on? 1.44?
unplug the cable,
force reboot,
select FASTBOOT,
when it shows FASTBOOT (in red),
plug the cable to your computer, and it should change to FASTBOOT USB
.
1.57,
it remains highlithed in blue. it freezes highlighted in blue.
there you got it. i recorded what happens, if you have patience 2-3 mins.
ignore the cracked screen, i disassambled the phone to disconnect the battery, in hope of something would work after.. and did not matter for me if that i damaged it, i have new full housing with touchscreen for it.

Booting to bootloader??

What is the sequence of the buttons to hold so you can boot to the bootloader from a device that's off? Not to Fastboot.
Volume down + power button. You run fastboot commands from within the bootloader.

"AP Fastboot Mode" --IS-- the bootloader...
Thanks for clearing that up, was driving myself crazy.

After rooting and unlocking bootloader, Can't boot in to clockworkmod recovery

So after using motoapocalypse to unlock the bootloader, I flashed the bootloader with clockworkmod recovery, Now when I try to boot in to it, it is just the icon of the android guy with his guts open.

Sorry, I probably should have worded that better. Bottomline is I can't boot in to the clockwork recovery after I installed it.

Remote command not allowed for unlocked bootloader

I want to flash custom recovery in my phone but it shows
remote: command not allowed
In bootloader, it shows that it is unlocked.
i get the same error when I type
fastboot oem devices-info
remote: command not allowed
I tried
fastboot oem unlock XXXXXXX(huawei code)
and it shows my phone already unlocked
and I tried
fastboot oem relock XXXXXXX
it shows
remote root type is risk
and I tried
fastboot oem lock
it shows
remote command not allowed
The recovery is still Huawei e-recovery, it asked me to download the update but it always failed when it comes to download package.
What should I do now?

To boot your recovery, disconnect from pc, press and hold power, vol up until a reboot, let go of power but keep the other pressed for about 5,6 sec more.

You may put screenshot comand line whith comand flashboot
Also try this TWRP https://drive.google.com/file/d/0B1Ez6wAY1mj6c0xxaTBUWmZVN1k/view?usp=sharing (Chinese)
Huawei E-Recovery is a secondary recovery. Try adb reboot recovery.

U don't have proper drivers installed.
Hi all ! I had exactly the same issue... The problem was solved by using the TWRP-CN image pointed by Druger ! (thank you mate) Any other attempt resulted into a fail. Twrp is of course in chinese language but follow this, and your life will be a bed of roses : youtube.com/watch?v=KOhR92EKD7A
Hope this will help
