[Q] Cannot get into recovery at all - One (M7) Q&A, Help & Troubleshooting

I have the dev model of the htc one and I have flashed a custom recovery but I cannot get into it! I did the cash clear and I made sure the fastboot power option was disabled. I also tried relocking the bootloader then unlocking it again but nothing. What should I do?
EDIT: nevermind, it all the sudden started working. Meh, oh well.

Sureļ¼Œ the bootloader is unlocked.
@Robin2719 please remove your imei from the screenshot
In another thread @xda I read that sometimes booting recovery did not work when the phone is connected to usb. download the recovery file again, erase cache, flash recovery, erase cache, disconnect from usb und try - good luck!
Go into Settings then power. Uncheck Fastboot. May help you.
Definitely uncheck Fast Boot, and try flashing TWRP if it still doesn't boot, to check if you can get any working recovery.
As far as I know TWRP is still not working on HTC One. And the fast boot option in Settings is not related to android fastboot. The fast boot option there is hibernate mode of HTC One which is not really related to android fastboot .

I know the difference in adb fastboot and power/fastboot.
I recommended disabling it as I had the same issue. I couldn't get into clockwork until I turned the power fastboot off.

[Q] How do I fix this

I tried to install a Viper rom (the latest one) but it kept saying error and when I went back to reboot it said that my phone might be unrooted and there was a button that said FIX and a button that said No, reboot and another one that said go back. Through hesitation, I clicked go back on accident and it rebooted. I don't know why but it got stuck on bootloop. Now I stopped the boot loop by holding down the power button and the down volume key at the same time to go back to the bootloader. Now, my problem is, how can I fix everything? I can't boot back to recovery because it goes on a boot loop and I can't factory reset either. I tried using HTC One All in one toolkit but it doesn't recognize my device. It keeps saying "Error: device not found" but my phone clearly says Fastboot USB. I need help ASAP

First of all, don't use a toolkit. They rob you of the understanding you need to fix problems like this.
- You should be able to use fastboot to boot recovery. Can you?
- Did fastboot/USB connection ever work for you? How about adb?
- If you get fastboot working (drivers?), you can clear the cache with "fastboot format cache".
- If you can't boot recovery to do the other steps (factory reset and wiping the dalvik cache), you have bigger problems. But I think these steps CAN be done from the bootloader. Maybe not all of them--I'm not sure what will work and what won't, as far as various combinations of "fastboot erase dalvik / fastboot format userdata / fastboot erase userdata", etc.
- First, focus on booting recovery. Get fastboot working and clear the cache if you need to.
- Note that IF you can factory reset through fastboot (I'm not sure you can), it will wipe /sdcard as well.
adb doesn't recognize my device. I don't know why. I can't boot to recovery either.
Same problem
Hi mate i got the same problem as you

I did the same thing like you.
Adb only works within a working os or in recovery.
If you PC is not recognizing fastboot/adb drivers, install them from here

[Q] Bricked Phone - Save Photos/Videos? (Stock Everything, No Root)

Hey,
I have a AT&T HTC-One, all stock with locked bootloader.
Currently, stuck in boot loop where if you turn on the phone - it will just keep rebooting itself over and over until the battery drains. Only way to shut off would be to boot into bootloader and power down.
I could care less about fixing the phone at this point. But I have lots of pictures that I would rather not lose.
I searched around and tried to flash TWRP recovery in order to mount the sd card to my PC. However TWRP failed to flash since my boot loader is locked. I can unlock the bootloader but I will lose all my data.
Is there any way I can salvage data off my phone? Any help will be appreciated.

did you try fastboot erase cache
Extract the zip below to c:\
then from c:\fastboot - right click - command prompt here
in the command windowtype
fastboot devices
your device serial no will be here
then
fastboot erase cache
fastboot reboot
hopefully your phone will reboot on it's own
Your case reminds me why I unlock and flash custom recovery the first day I get a new phone. Backups !!

Thank you for the quick reply.
Yes, just tried it and still no dice. Reboot still puts it back into the bootloop.
...definitely lesson learned.

sorry to here that ... unfortunately everything else will be destructive... but your phone may be savable
If you want to proceed post your fastboot getvar all results minus your serial no and IMEI and I'll help you get the phone going again

Can't access fastboot mode

I was gifted a Nexus 6 after my 5X died. As far as I know the device has never been OEM unlocked, much less flashed with anything. I've unlocked developer options and allowed USB debugging and OEM unlock but when I try to use power+Vol(-) to get into fastboot mode nothing happens, the screen is just black. When I bridged the device using ADB I could see the serial number and tried using the boot into recovery mode command and it rebooted to the same black screen. When I used fastboot commands on the black screen I could see the device and tried running fastboot oem unlock, it did something but wasn't successful in unlocking it. I'm not prepared to just start running fastboot commands blind like that without being able to see what's happening on the device's screen.
It's a curious problem, has anyone ever heard of it happening before? I can't find anything similar when I google it.
All I really want to do is clear the Dalvik cache and flash the latest factory image because currently, even after doing a factory reset, the device is very slow and laggy.
Is there anyway I could clear all the caches etc without going into fastboot mode or does anyone know of any fixes I could use so I can see the recovery menu?
If you boot to bootloader mode, then "fastboot boot <TWRP.img>" you might be able run twrp on your pc and clear caches. If it works, I'd consider factory resetting. You can get twrp here: https://dl.twrp.me/shamu/
I have considered that. But that requires OEM unlock, no? I still haven't managed to unlock it yet. The first time I tried, I said yes to unlock (it involves using the rocker to select a response, which I can't see the options for) but in the command window it said it failed (can't remember the error message though). I was going to try again today but because I couldn't see the options when I tried it said I'd cancelled the operation and I was too scared to try again in case something went wrong.
But, do you think I should try the fastboot oem unlock command again? I definitely need OEM unlock to install TWRP, right?

To install twrp yes, you need an unlocked bootloader. This doesn't install twrp on the device. I believe it should work. It certainly shouldn't hurt. I've been unlocked since the N6 came out so I can't double check for you.
If it doesn't work, I'd be a bit inclined to just flash a factory image thus ensuring everything is stock and current. You might want to wait for others to chime in, but it's what I would do.
You may consider downloading Nexus Root Toolkit, works like a charm : ).
I can't just flash the stock bootloader without OEM unlock, right?

Correct, you need to be unlocked to flash a factory image, that includes the bootloader. See Google's instructions. Don't get confused by the "fastboot oem unlock"
vrs "fastboot flashing unlock" we are an older device and use oem unlock. The other is for the 6P and newer devices.

Successfully unlocked. TWRP didn't help, still can't see the bootloader menu to access the recovery. I'm flashing the factory image now, hopefully a new bootloader will fix it. If not, is there anyway to clear the Dalvik cache using fastboot commands now the phone is unlocked?
UPDATE
Still a black screen even with a new bootloader flash. I'm assuming now this must be a hardware problem

I think the command is "fastboot erase cache". Also, unlocking will have wiped the device.

Why not just flash the entire factory image you got the bootloader from? What can it hurt? It would be really odd for this to be hardware if you can boot into the ROM and the screen works.

Nexus 6 stuck - Google logo/Unlocked symbol

Hi,
So I flashed a stock rom 6.0.1 from google website using a standard procedure, the device booted for the first time, signed in and set up. Then when I restarted the device, it is not stuck on google screen with bootloader unlocked.
Can anyone help me how to fix this?

Old post, I'm guessing you've moved on, but...
What ROM was on the device before you flashed the 6.0? The boatloader updates with stock ROMs. I there is a 7 bootloader, it may interfere with the boot of a 6 ROM.
If you are unsure, you should always go with the newest stock release.

I would try clearing the caches and/or userdata before manually installing the system partition again.
1.) Reboot to the bootloader. (reboot and press and hold the volume down button until booted)
2.) plug-in the usb cable
3.) Open your terminal and type:
Erase cache
Code:
fastboot erase cache
Erase dalvic-cache
Code:
fastboot erase dalvic-cache
Erase userdata
Code:
fastboot -w
