Hi, i have a weird issue. Whenever i boot my phone using the power button it just goes to fastboot mode. From there i can start the phone pressing start with the power button so i have no problems at all, it's just that it forces me to go to fastboot everytime i want to turn it on. How can i fix this?
I have to state that i am on custom rom 8.1 pixel experience xt1687

You are in OEM fastboot mode most likely, clear it with:
fastboot oem fb_mode_clear
And then reboot... Should go straight to OS. Otherwise, include a getvar all, it will tell the reason for going to fastboot.

Much thanks that worked .
Mine reboots into recovery every time. It doesnt matter if i power it up, or just restart, but he restarts into recovery every time, and to start it i need to reboot into bootloader (from recovery) and then start it from a bootloader.
Will the same fix work? Also, where do i type that?

Your problem is different. You need to use ADB with phone hooked to your PC, and execute the following commands.
Code:
adb devices
adb shell
dd if=/dev/zero of=/dev/block/platform/soc/7824900.sdhci/by-name/misc
or execute the last line in a terminal shell inside TWRP.
Code:
dd if=/dev/zero of=/dev/block/platform/soc/7824900.sdhci/by-name/misc

Alright, fastboot is useful for development but I am posting it here because it is a general topic and won't be discussing developing.
fastboot is useful because you can test kernel builds without having to worry about it not booting, if it doesn't you just remove battery and it boots normal.
While device is off, hold both volume keys(up and down) and power, keep it held until the device goes black but lit screen. This is the bootloader screen and lets you run fastboot commands.
Another way is to have a rooted S7 and in terminal do the following:
su
reboot recovery (you could do adb reboot recovery from your pc without using terminal on device)
I think razor knows because he mentioned this elsewhere, but in case anyone sees this and tries reboot recovery...
Fastboot is actually
adb reboot bootloader
reboot recovery enters recovery and results in a factory reset
Please tell me more about

Hi brother, i have one s7 here model s7-202u and i try to flash and cant boot...
Always appear on screen about fastboot mode...
And i cant boot this tablet.
How do you guys boot to fastboot if you have turned your phone off? I mean the actual fastboot ("black Huawei logo") not the recovery and not the pink bootloader. I can get to it if I reboot my phone if I press reboot and then bootloader, but is it possible without it?
Seems like there is no other way. Right now I can start it in fastboot mode with "adb reboot bootloader" and the custom ROM I have on right now. If anyone wants details, post here.

Weird discovery I made. While trying to flashall it says the device is "swordfish"... If I flash system.img separately it says "no partition table exists". Anyone has used fastboot before?
Nice. With the new Android version, the product shows MSM7630_SURF. It now properly boots to fastboot without going to charging too, so thats an update.

Thanks! I was trying to set up my UDEV (51-android.rules) and your post helped me boot into the bootloader mode to get the right idVendor & idProduct codes.

I tried fastboot, but I just get a black screen with huawei logo. No any function, no adb connection, no menu entries or anything and no buttons work. And I can exit only by remove battery. Is this right?

There's an external tool called fastboot which handles that. There you can reboot or even continue the boot.
Fastboot is broken as far as I know, no partition table exists.
Sent from my U8800
You mean the fastboot from adb tools which can used from command line? This cannot work because there isn' t adb connection on bootloader mode.
Or is another tool which can be flashed or something to device?

I think you are confusing pink screen with fastboot/bootloader. The fastboot is the node where it stays in the Huawei logo.
Sent from my U8800
No, I know the difference. I get this screen, but nothing else. On my previous device, fastboot has some functions included flash rom, reboot and some else that I don't remember. I also could from adb to use fastboot command.
On X5 I just get this screen.
Maybe they disabled that in B522 too, I am not sure. It was bugged anyway. I only tested it on B138 and B518.
Yes, I have 522 and I thought this too. I've tried on B138 1-2 times and was the same huawei logo screen only too. I didn' t tested it more because I thought that just this mode is disabled and used pink mode only. In B138 sould appear something else on screen, or only commands from adb work?
SOLVED
run
Code:
fastboot continue
solved the issue
I've ran the command
Code:
fastboot oem unlock
And now all I can see is the oneplus logo for one seconds and then it is disappear and shows again and again.
I can make it stop by long hold the power key, but when powering it off it is still the same.
Nothing happend when trying to open the device to recovery mode
Thanks
I tried with different drivers etc. but its just don't work, i downloaded TOOL ALL IN ONE, but this said that device was found but not said what or which device, only when phone is normally started i see it on the list of "adb devices" and in TOOL ALL IN ONE. Please help thanks in advance =)
Fastboot is an entirely different mode from adb, and as such it requires a different tool. In the console there is a command "fastboot", which is what you need to use to interact with the phone in fastboot mode. You can boot into fastboot mode from power off with the USB to computer plugged in by holding Volume Down, or it might be possible with TOOL ALL IN ONE, I haven't used it much.
Some basic commands:
fastboot flash unlock path/to/unlock.bin # This will flash the unlock bin
fastboot getvar unlocked # This will check if the device is unlocked
fastboot reboot # This will reboot the phone into normal mode, since powering off by holding the power button is a pain
To flash TWRP, there's a more advanced process with some specific requirements, but I'd be happy to share those if wanted.

Yeah, so I wanted to flash TWRP but it doesen't seem to work i did what was said in many guides but maybe if you tell me how to do it, it will work =) Thanks
So i tried to flash TWRP with the TOOL ALL IN ONE, everything was okey but then error happened called "Unknown device"
First of all, which version of G6 do you have? The US997 one, or the H870?

H870
For H870 I'm not entirely sure, but I know that for the US997 you have to do a special procedure to make it permanent. Make sure you back up everything first, too.
With the phone in fastboot mode and a computer connected with fastboot installed and the twrp zip downloaded as "twrp.zip" (or whatever you want):
Make sure the bootloader is unlocked: fastboot getvar unlocked (should return "yes" or "true").
Flash the recovery: fastboot flash recovery twrp.zip (replace twrp.zip with the relative or absolute filepath/name).
Unplug the phone from the computer and reboot into recovery by holding Power and Volume Down. When the logo appears, lift your finger off the power button briefly and then continue pressing.
When you get to the factory reset menu hit yes twice, then the phone should boot into twrp (it may flash the LG logo, I've had different behavior on different phones. You won't need to hold the Power-Volume Down combo any more).
In twrp, swipe to allow modification, then in the Wipe menu select Format Data (and enter yes). This will wipe the phone, so make sure everything was backed up beforehand.
From the main menu go to the Reboot menu and select Recovery.
Here it might vary from the US997. Below are suggestions which I think are needed to have it work.
Download the no-verity-opt-encrypt zip, and connect the phone to the computer.
Once it's rebooted into recovery mode: adb push path/to/no-verity.zip /sdcard/
Then from the install menu in twrp install the zip.
Reboot into System from the reboot menu on the homescreen of twrp.
That should do it all.
Last week i received a notification the 8.1 Oreo update was available for my Moto g4 Plus.
Downloaded the package and hit the install button. My moto restarted in order to perform the installation.
However, since i had TWRP installed and thus bootloader unlocked, the phone restarted in recovery mode.
Downloaded a TWRP 8.1 rom and installed it without a problem.
Unfotunately everytime I restart my Moto it starts up in fastboot mode.
Bootloader log shows: Fastboot Reason: reboot mode set to fastboot
From bootloader I can start the Android OS, but i wan't to get rid of this reboot mode
I tried tools like "Android Multi Tool" and "Free ReiBoot for Android" but this reboot mode can not be cleared.
Anyone encountered this problem and how did you fix it.
Thanks in advance
Try this:
Reboot your device to the bootloader.
Connect your device to your computer and open an ADB terminal on your computer.
In the ADB terminal, type 'fastboot devices' without quotes. Press Enter - your device should respond with its serial number.
If so, then type 'fastboot oem fb_mode_clear' without quotes. Press Enter, then reboot your device.
That fb_mode_clear command seems to clear a flag that keeps your device booting into fastboot (usually for OTA updates).
I have Tried that option as i found it as one of the possible solutions for this issue.
the clear_fb unfortunately does not remove the fastboot mode on my moto.
