KFHD 8.9 Fastboot?

Has anyone had any success getting a factory cable to enable fastboot on the 8.9? I've had no luck. I'm thinking amazon locked out this method. It can still be accessed using adb but that doesn't help if you are in a boot-loop and can't get adb to recognize it.

What about using
fastboot -i 0x1949 getvar product
that works for the fire to put it into fastboot, even when ADB does not see it.

Did you test?

It does put it into fastboot. I put it into fast boot and was able to take it back to normal boot.

adb reboot bootloader will take you into fastboot mode on the KF HD7, probably work on the 8.9 too.

Just to confirm, you had the power off to the device and plugged in a factory cable and the device booted into fastboot? Like I said I can get it to boot into fastboot through adb, but if the device ever gets into a loop i want to be able to get into fastboot via factory cable. Maybe my factory cable is not working properly, it was starting to act funny on the KFHD 7 but it would still work to get into fastboot.

Just tried this. Suprisingly it works. I thought that command was just used to get the product info. I had the device powered off, typed the command(says- "waiting for device") , and plugged the device in- voila fastboot mode.
Thank you.
Edit: Any fastboot command entered before the device is turned on will enable fastboot mode as soon as it is powered on.

NOT NORMAL BOOTLOOP please help!!

My phone suddenly turn off and now it keep bootloop EVEN IN FASTBOOT. I cant even go into recovery or either fastboot.
I still remember before the restart occur my battery left 70++ until it bootloop till no 0 battery . till now cant even charge enter recovery even in fastboot USB mode. it just keep bootlooping .

That is strange and unfortunately not much you can do about it if it won't even stay stable in fastboot mode. What about RUU mode if you can get it there does it reboot still try this.
Power off the device and connect your usb cable. In the command window type
Code:
fastboot oem rebootRUU
The command window will show "waiting for device" Now boot the phone to the bootloader and fastboot it should go strait to RUU mode (A black screen with silver HTC logo). Does it still bootloop ???

Sorry man, There's not much you can do with it like that. There's no way to flash anything. Unless Dexter's Unbrick project will work on it but I doubt it very much.

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.

When I remove the usb cable it's still the same. When i try to press the power button it vibrates shows the low battery red lightbolt and dies. If you mean by erecovery emui recovery, then it looks like it's not installed.

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

HTC One M7 not able to get into recovery mode or bootloader

Good Morning,
I have an HTC One M7 here that no longer works. I found out that I can boot into the HBoot, but I can't really choose anything.
I mean, if I select e.g. Bootloader / Fastboot, then the phone goes into the menu of the bootloader, but after that I can neither select something in the menu nor access the device via Fastboot. (Using Arch Linux with Android Tools)
I also tried going into recovery mode. When I select "Recovery" in HBoot, the phone reboots, gets stuck on the boot logo, and turns off.
I would appreciate any help from you ^^
Cheers,
TheGoliath

Linux have some issues with fastboot drivers.
Try to get an "fastboot getvar all" from windows and post here(remove sn, imei).

The same goes for Windows. The phone basically freezes when you select something in HBoot. For example, I'm trying to start from HBoot. When I select Fastboot it brings up the submenu (ok). But I can't move within the entries and it doesn't change from Fastboot to Fastboot USB either when I connect it to a Windows / Linux device with the correct drivers installed. When I try to go into recovery, it vibrates, the HTC logo with the white background appears, and then it turns off.

Getting into recovery worked like a few hours ago, but not anymore.
From there I was able to get into the bootloader (still buggy, but I was able to print Vars via Fastboot, for example)
But when trying to RUU (fastboot oem rebootRUU) the phone got stuck with "Verifying: 3". After turning off and restarting the phone, I was greeted by the HTC logo on the black background. Normally I could flash the RUU through Fastboot, but the phone was not recognized by Windows or Linux. Therefore, unfortunately, no success so far.

xz2, can't acces bootloader

I tried the guidelines to boot into bootloader, I'm using xz2 non premium/compact, I press vol- a while and connect USB cable to PC but I never boot into bootloader, even when I try using adb command "adb reboot bootloader" it just reboot into normal system, what can I be doing wrong?
Also I have no update, I'm still on 8.0.0,I keep checking and it says you're using latest Android version, how come?

Do you Know of any tricks to boot fastboot/bootloader,I want to unlock it, the current methods not working,I get a black screen and green/blue notification light (-vol and connecting USB cable from pc to phone) when I input fastboot commands, it says "waiting for available devices" and fastboot devices says no device connected, but adb devices (when in normal boot) recognises my device

Then the fastboot driver doesn't work correctly, is not correctly installed or the wrong got installed, while the adb driver is fine

similar problem: fastboot issues
I apparently don't have standing to post my own thread, so I'm replying to this one which is similar. My apologies.
I've downloaded adb and fastboot on my win 7 machine to unlock my bootloader on the way to rooting my xz2 compact. Fastboot will not recognize the phone. Adb does recognize it, and fastboot recognizes my Moto X DE, so both utilities seem to be working fine. Additionally, using 'adb reboot bootloader' cycles through a green, red and then a faint blue led, the latter which just stays there continuously with a black screen.
I've spent quite a bit of time on this looking for a solution, so I'm turning to you all for help.

Sorry, if didn't communicate this well. I need to unlock the bootloader using the fastboot command, yet fastboot overtly doesn't recogize the device. (no recovery screen menu is a separate problem). so,
'fastboot oem unlock' returns
'< waiting for any device >'
even though the phone is recognized by adb and other phones are recognized by fastboot.
How do I get the phone to be recognized by fastboot is the main issue.
