I am trying to get into fastboot mode to unlock my bootloader. I enabled usb debugging, and allowed the oem unlock mode. when I press volume down and power button, i do not see "fastboot mode" anywhere. in device manager, my device shows up with a exclamation mark and triangle. I installed the google usb driver via sdk manager. when i type "fastboot devices" on my desktop, my 6p does not show up. how can I get this to work?

Holding power + volume down will get you to the bootloader, this is fastboot mode. Is the phone in this mode when issuing the "fastboot devices" command? Does Windows show any driver installation/update dialogue when you connect the phone in this mode?
Yes, it is.
I believe a driver installation popup came up before.

It also tells me to connect a usb data cable, when it's already plugged in.
So I found a usb driver, and it works now. Up to the point where I go into TWRP, but it asks for a password to decrypt the data. So I enter the password I use to get onto my phone, and it gets to "Unable to mount storage. Full SELinux support is available." Where do I go from here?
Are you using the Android N Dev Preview?

I'm currently attempting to root my atrix but I've come across a problem that I can't seem to be able to solve through googling or otherwise.
I'm using the tutorial stickied on the Atrix homepage labelled [HOWTO MAY16].
I got as far as step 8 and my phone passed the sbf flash using RSD lite but continuing on with the process to step 13 where it is asking me to type "fastboot oem unlock" into cmd I get an error message telling me that cmd is waiting for my device but nothing seems to happen.
I've tried reinstalling drivers (64 bit), restarting computer, restarting phone, trying different leads/usb sockets with no change to my result.
The exact thing that I'm doing with cmd is to navigate to the platform-tools folder, open adb, open flashboot and then attempt fastboot oem unlock.
Additional information:
UK Orange Atrix 4G running 3.4.4
using IHOP sbf file
running windows 7 64-bit, using the 64-bit drivers.
Do you have access to win 7 or xp? Win 8 is really new and possibly that could be the problem. Worth a shot.

Ops, typo. I'm running Windows 7 64-bit. I'll edit my post when xda allows me to.
Unlock
Enter the bootloader program by powering off the phone, Hold the volume down key and the power at the same time. The phone will be in the bootloader program when it powers up, use the volume down key to scroll through bootloader menu options. the second option will be fastboot program. Select the fastboot option with the volume up key, this will enter the fastboot mode of operation. Connect the phone to the PC via USB cable. Enter the directory where the fastboot program resides on the PC. Type the Fastboot oem unlock command. If sucessful a message will display on PC retuned by the phone. Reboot phone and unlocked will display in the upper left corner of the phones display. Continue to follow the original post, flash recovery, root phone, flash custom ROM. Happy Flashing, Enjoy! :fingers-crossed:

I just gave it another try and it gets stuck after I type fast boot oem unlock. I definitely have the right directory but I still get stuck here. Cmd just tells me it's waiting for my device and stops there. I think it's a driver issue after a bit of googling but the official drivers aren't working. This socks.
I had a similar problem with my device not showing up. There wasn't really a big fix for it but I just waited longer before trying to execute the command. I'm not sure if you're experiencing the same thing I did but when it couldn't detect my device it just hadn't been recognized by the computer yet. Make sure your drivers are working (connect usb and select every option on the pull down menu and are sure the device gets installed). After that do the same thing as before for fastboot but make sure you securely plug it in and wait for the computer to detect your phone before you move forward

Hi,
I ran into a problem with my Nexus 4, the plan was to unlock the bootloader using my mac and fastboot. (used this as information but didn't follow it step by step, youtube.com/watch?v=fHZJ2f6JLw0)
I turned off the phone and went into the bootloader with volume down + power button. From here i used "fastboot devices" to secure that i was able to communicate with the phone. My device showed up together with an error message saying "ERROR: could not get pipe properties nexus 4".
Before doing any more i wanted to understand what this message meant so I searched the web without any success. I booted up my android, turned on usb debugging and used "adb devices". This time only my devices showed up and no error messages. I used the "adb reboot boatloader" to access the bootloader once again.
I still had the same error message with "flashboot devices" as before.
From here i didn't do anything more, I may have disconnected the usb from the computer while the terminal window was open and the phone in bootloader but without running any command from fastboot.
So I didn't run "fastboot oem unlock" or anything else.
I turned off the phone and tried to access the bootloader one more time with the volume down + power button. It didn't respond to this any more and nothing happened, the device just stayed turn off.
I turned on the phone and tried to use adb to access the bootloader but now when running the "adb devices" it just responds "-bash: adb: command not found".
I have tried to restore the phone thru the android setting meny without any success. The phone is working fine without any problem except i cant access the bootloader or use adb.
So I desperately need help from you guys. :crying:
Have any of you heard of this problem before?
Regards Rasmus
I have to change my statement.
Actually I succeeded rooting and installing CWM recovery using a win7 computer together with Nexus4 toolkit.
The issue i have right now is that i can't start the device into bootloader using volume and power buttons.
To access bootloader i have to go thru the toolkit and this can be an issue in case i flash a bad rom or kernel and can access android usb debugging.
Is it possible to restore the bootloader?

Are you holding the down volume and pressing the power button?
What OS is the computer that you are using? If you have reset the device, make sure that USB debugging is checked again. I know it sounds dumb, but a lot of times it's the simplest things we forget. Once you factory reset your device, it resets everything.
If you are on Windows 7, make sure you are starting the command prompt from the same location your adb is installed. If you are on Ubuntu or another Linux distro, please let me know which one. This seems like it should be an easy fix for you, but a little more info is needed. Thanks!
[Tools, Tips & Tutorials] [kenzo]Entering EDL mode via Test Mode Screen
Who cannot enter EDL mode from standard Android boot and have no abilty to boot an image from FastBoot mode, you could try the following:
Switch the phone off.
Press and hold both Volume keys and Power key.
As Mi logo appears on the screen, release all buttons.
After several seconds, Test Mode Screen should appear (SYSTEM INFO, KEYPAD BACKLIGHT etc.).
Open Device Manager in Windows.
Connect the phone to the Windows computer (no matter which cable end is inserted first).
If ADB drivers are installed, "Android device" branch should appear in Device Manager, containing "Android Composite ADB Interface" and "Xiaomi Composite MDB Interface". Addionally, there should be "Portable devices" branch with "Redmi Note 3" device. If some drivers are not installed, install them.
Execute "adb devices" command to check if ADB connection is established.
If no devices are shown by ADB, wait a minute until "Redmi Note 3" device gets the "!" mark. Repeat "adb devices" command.
If "Redmi Note 3" device is not marked by "!" after a minute and ADB does not list the phone ID, try to disable "Redmi Note 3" in Device Manager.
As the phone ID becomes listed by ADB, execute "adb reboot edl" command.

Keep repeating "adb devices" until it reports connected.
Thought this deserves a thread of it's own. If anyone tried to get to EDL via volume buttons, will probably know how difficult it is.
not working
Redmi note 3 , screen on while put to charging, I tried to start mobile , by pressing Volumn + , volume - & Power buttons simultaneously, tried several times but unable to start mi note 3
Hi all you good people, I have a nexus 4 with a bootloop also additional problems are:
1. Im a complete novice and can only do things with simple instructions (sorry!)
2. No debugging mode was enabled
3. I only have a Mac
4. The Mac is not showing the device with the android transfer app and also I've tried a few things in terminal - but again comes up with device not found.
I can get to the Postboot mode by pressing the power/volume buttons so thats okay, on that screen it says: SECURE BOOT - enabled & LOCK STATE -locked
I have tried all the clear cache/restore factory on the recovery screen and taken the battery out for a while but to no avail.
thanks in advance!
You should unlock the bootloader and then flash a stock Google image. Unlocking the bootloader will wipe all data on the phone.
First thing would be to at least get the phone to recognize fastboot commands. Not sure if this will help: http://forum.xda-developers.com/showthread.php?t=1917237

Thankyou that is really helpful how ever when I type in: ./adb devices it dosnt list any devices including my phone, if I try a command such as:
./fastboot oem unlock
it just hangs on: "waiting for device"
The USB cable is good as I tried it with another device - could it be a damaged USB female socket on the device itself?
thanks
Adb commands will not work when the phone is in fastboot mode.
With the phone connected and in fastboot mode, type "fastboot devices" and press enter. It should return your phone's serial number. If not, try different USB cables and USB ports.

Fastboot mode is when you boot into the bootloader where it said secure boot enabled.

To enter fastboot mode on the phone, power off the phone, press and hold volume up + volume down + power at the same time.

Thanks tried this - and and nothing came up with the command 'fastboot devices' - thanks anyway
If nothing comes up when executing the command, that tells me the drivers are not installed or the connection between the phone and computer is not good.
HI
How can I install the drivers on a mac? thanks

Maybe you need to allow your computer when it's asked on the phone.

what you mean when is phone is fast boot there has no display controls
Do it when the phone is ON, just after the USB debugging option is ticked, put your cable and the box for computer authorization will appear on the phone.
Don't know the way to do it when a phone is off.

in the normal system mode then I can see it but not in the fastboot mode
Adb won't work in fastboot mode. Try "fastboot devices" when in fastboot mode.
When phone is turned off and connected via usb (vol+) to pc then type:
fastboot devices
When phone is turned on and connected via usb to pc (usb debugging on) then type:
adb devices
