Bootloop, no coenct via ADB, to short for recovery ! - One (M7) Q&A, Help & Troubleshooting

Yesterday my Device restart.After Screen don't showing something,but i had vibration response from Home button.
Than Phone reboots again and hangs into bootloop.Tt reboots every 3 seconds.No time to enter in recovery.Also tried to connect with adb to erase cache, but after some hundreds attempts it doesn't work, because no device detected.Also tried to wait until battery is empty.
Same time no AC led is showing, also no physical Buttons are blinking.
Is there any chance to fix it ?

You can boot into the bootloader?
And if you are in fastboot the command is
Code:
fastboot erase cache
and not
Code:
adb erase cache
.

no, i cant boot into bootloader, also no recovers because when 3 or 5 seconds passed phone reboots again and again.
Also tried all in one tool.Strange will be that reboots begins automatic after some time on ac.

Really strange...
adb don't recognized the device, right?

no idea, sorry. i just wanted to tell you that i experienced this strange issue too, but i was able to boot the device.. so maybe it's useful for you to know that it was caused by the HBOOT.

i have but wont go to fastboot usb
what did you do with it? If you've got empty battery try to keep it on the charger for a while. Ignore it if there's no led light.
Or have you flashed a custom rom? If so, did you flash the boot img? did you also erase cache in that case? If not, go to fastboot, connect phone to computer and use the fastboot erase cache command.
EDIT: just saw your post about not getting to fastboot after I posted hmm weird indeed..

Help, need help getting out of a bootloop

I need help getting out of a bootloop that I got stuck in trying to change ROMs today to ViperOne 6.1.0 because I was on an abandoned and unupdated ROM, anyway when I flashed it at the very end I got error 7 and accidentally just clicked the reboot button on CWM. Anyway, now I'm in a bootloop and it tries to reboot into recovery first and briefly the CWM logo appears then it goes black and goes to the regular rebooting screen and so on. My laptop is also having a problem recognizing my phone though which I feel is really complicating things so trying to do bootloop fixes in ADB is tough for now and I am really confused and could use a little guidance here.

[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.

[Q] HTC one (m7) Cannot load recovery

Hey guys..
I have a problem with my HTC one (m7) and it doesn't start up. The HTC screen loads up but turns off and then restarts again. And does the same process.
I can get into the hboot screen where options such as Fastboot, Recovery, Factory Reset, Simlock, Check SmartSD, Image CDC and Show Barcode show up. If I try and go into Recovery, the start of recovery page blinks on screen for a second then the phone restarts.
So, I can't get into recovery and try to factory reset the phone...
Please help, this is the first time I have encountered a problem like this.
thank you,

Well, it's a fastboot command.
Install adb and fastboot on your PC, then plug your phone and run the command in command prompt.

but the phone does not hook up to the pc, because it does not start up. it is stuck in rebooting..
even if the phone is plugged in, while it is at hboot, the pc does not recognize it, i think?
Update: yup, the phone is not being recognized by the pc, so it cannot do any functions to it. not quite sure what to try out at this point.
Update 2: hi thanks again for the suggesetion. I plugged in the USB in a different USB slot on my pc, and I heard the sound of connection. I am currently in the Recovery page. I think all I have to do know if download a stock rom and run it through CMD and hopefully it will start.
thanks again. i'm new to this site, so if there is some sort of review button or thumbs up or whatever, please inform me so I can give my proper appreciation.

Phone can't boot stuck at "Your device is booting now" Please Help

Hello, I wanted to install TWRP and ROOT my phone. I flashed TWRP using adb terminal. But when I tried to boot into TWRP it was stuck on "Your device is booting now..". Then if I held the power button for few secs it rebooted normally. So I tried to google it and I found adb command that reboots to recovery
Code:
adb reboot recovery
. When I executed the command it rebooted to the "Your device is booting now.." screen and it stays like this forever. No button combination works to reboot the phone if i hold power button it reboots shows honor logo and then shows the "Your device is booting now.." screen. I waited for the battery to drain and then i put the phone on charger and when I tried to boot it, it was the same. Now when I try to reboot the phone it shows ultra low baterry symbol and then boots to "Your device..." screen.

Which twrp you flashed? Check the correct twrp in my signature for honor 5C repository.

Hi hassanjavaid8181
I think I have the same issue here, phone is stuck on "your device..." screen forever and it's impossible to do anything else (reboot ends up on the same screen).
How is it possible to flash twrp or stock recovery if we are stuck on this screen ? Fastboot doesn't see the phone...

Did you try all method to going in fastboot.by adb fastboot command or by pressing vol- and power button?
Hi guys, thanks for your replies.
I somehow managed to boot to fastboot after waiting for the battery to go out completely. From there I used the following commands in ADB from the extract of a stock update.img :
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot reboot
And it worked ! The first boot was veeery long and now it's normal again.
Now my last concern is that I still have bootloader unlocked. As I wish to come back to factory state and avoid the warning message on boot, do you guys think it's safe to re-lock bootloader ?
I'm kind of scared to try anything else and screw the whole thing now
Thanks again for your support

Can you please explain to me how did you managed to boot into fastboot? I tried waiting for the battery to drain completely. Now I can't fully charge my phone. When i connect it with charger. It starts normally charging like it would with 0% battery then after a few moments the honor logo shows up and then the screen "Your device.." shows. When I try vol- and powerbutton it vibrates and shows the red lightbolt then after few moments it boots the same way into the your device screen. When I connect it to the pc it doesn't react. I don't even hear the classic windows beep sound.

You need to press power + volume down key to boot into fastboot. Keep trying 4-5 times sometimes it takes due to wrong press

So I managed to get into the fastboot. Where can I get boot.img, recovery.img and system.img? I have downloaded some update.zip files from this russian site (first 5) http://hwmt.ru/hwmtsite/firmware-database/?firmware_model=NEM-L21&firmware_page=0. But I don't have boot, recovery and system images in these zips.
I also tried reboot in fastboot but its still the same:

Meaning the fastboot is accessible.
Now you have firmware zip, extract it amd you will get few files. Use dload method as given in my signature and you are good to go.
Else use Huawei extractor and browse to update.app you just got in above downloaded zip. You will get boot, recovery, system img you need.
I downloaded some firmware versions and extracted them. I don't know which is for my device. So I tried one of them. I flashed boot.img and recovery.img but I din't flashed the system.img, becouse it was too big. When I tried to reboot the phone it was the same. The fastboot was no longer accessible. I put the phone into servis but they didn't fixed it. it's the same but I can enter erecovery
