In fastboot mode, message "OTG NOT MOUNTED, File NOT FOUND" - One (M9) Q&A, Help & Troubleshooting

I have used the SDK tools trying to root my M9.
Activated developper mode, OEM unlocking end usb debugging.
In bootloader mode I can use the command line "adb devices" and it list in terminal a number for the device.
If I do the same in fastboot mode ("adb devices" at command line) then it doesn't show any device number and keeps searching.
When in fastboot mode I got the following message:
SD MOUNTED
OTG NOT MOUNTED
File NOT FOUND
Can somebody help me to solve this issue pls!!

I can see my phone and the order under Windows but i can not control my phone with the fastboot command.

And when you use adb to reboot to bootloader, what happen? Do you have "Minimal adb and fastboot tool" installed?

Sorry for my question, what´s the differents about adb and fastboot tool? I have install the last version of minimal adb and the fastboot tool, also the Windows driver for the phone. Debugging is on. I try to connect my phone about the fastboot terminal. When i try to set the phone into the bootloader mod with the fastboot terminal and the equivalent command, fastboot say´s "searching phone". My phone does not react.

So, you connect your phone, open minimal adb and fastboot too, run "adb devices", you see device id? If yes, run "adb reboot bootloader" . Phone shoult reboot to fastboot mode. Then run "fastboot devices" to see if it is connected properely.
i did it, like you described, but i see not my device id. Only the note "seach device"
Is it possible that TWRP is defect on my device? Is TWRP necessary for fastboot or only for root?

No, you should be able to use adb and fastboot with stock recovery.
After first adb command you shoult approve authorization on your phone.
Here is screenshot from minimal adb...
Phone must be in MTP mode.
And here is phone in fastboot
Many thanks for your help, now I m in my bootloader.
2 problems i had.
1. My daemon was not started correctly, i have not seen my device.
2. I used the wrong command. I started with fastboot, not with the command adb device. I tap „fastboot reboot-bootloader“,but the correct command is “adb reboot-bootlader“
Now i have seen my phone is unlocked, i hope i can root my android 6.

fastboot not detecting phone

hello all,
I am trying to install android 2.0 preview. I installed android studio and I am able to get device listed using "adb devices" command.
I am able to enter boot loader using "adb reboot-bootloader" as well.
but in boot loader when I try to run fastboot oem then it says "waiting for an device".
also "fastboot devices" does not return anything.
E:\Android\sdk\platform-tools>fastboot oem unlock
< waiting for any device >
I can see "Kedacom USB device" is installed while in bootloader mode. can anyone help me? thanks
I am using windows 10
Same here, not detected by '
Code:
adb devices
' or '
Code:
fastboot devices
'. Windroid toolkit stuck at "rebooting device" while it is in Fastboot mode, and if you reboot it manually, it gets stuck at "unlocking device". Drivers are installed, maybe not properly?not properly?
adb devices works for my case after downloading latest sdk. but fastboot is no go.
windows xp ???
Sorry forgot to add that details - windows 10
Have you found a way to resolve this?

Issue unlocking bootloader

I'm trying to unlock boot loader on my device but, when I reboot into boot loader I don't get an option for "fast boot". The options I do get are to reboot, reboot in download mode, reboot in boot loader, reboot in recovery, and shut down. Any ideas or maybe any precursors I've missed?
fastboot (and adb) needs to be installed and running from your PC, you reboot in to the phones bootloader then from a command prompt or terminal on your pc you issue fastboot commands to your phone which is connected by USB.
No luck

C:\Users\Delprete>adb reboot downloader
adb server is out of date. killing...
* daemon started successfully *
error: device '(null)' not found
is all I got. I downloaded and installed fastboot to the pc. The directions that I'm following from HTCDEV.com say to reboot into download mode and then load fastboot from the phone.
Use the adb and fastboot from here http://forum.xda-developers.com/showthread.php?t=2317790
Make sure you have usb debugging and oem unlocking enabled in developer options of your phone.
Once in download mode send the fastboot commands from your pc

Does ADB work with locked bootloader?

I have a LG G7 (LM-G710EM) with locked bootloader (stock version: V10h). I can easily enter fastboot mode. When I send the command "fastboot devices" (from a command window running ADB) it returns a list with the serial number of my device. So, it seems to work. But if I run the command "ADB devices" then I receive an empty list.
I don't want to unlock the bootloader. I just want to send specific commands required by some app to work properly without the need to be root. For example BetterBatteryStats requires the ADB command "adb -d shell pm grant com.asksven.betterbatterystats android.permission.DUMP".
I did already in my Moto G5+ with stock 7.0 (locked bootloader) and it worked. Is it possible to do the same in my LG G7 without unlocking the bootloader?
I just ran into a similar issue when giving BBS permissions. The solution that worked for me on my Verizon G7 was to select the USB connection notification then go to Photo Transfer mode. Right after that I got the authorization request on the phone to grant debugging permission to my computer. After that adb devices showed the phone. Hopefully that same tip helps.
ADB doesn't work in fastboot mode.

at the end I discovered what was wrong. to enter ADB commands there is no need to enter fastboot mode, just connect the phone (already switched on) to the PC and accept the connection from that PC. Then opening a CMD window, it's enough to type the command "adb devices" and the serial number of the phone appears, telling that the phone is ready to accept adb commands. uhff!!
LG G7 ThinQ ADB devices - nothing appears, no matter what I try (all of the above and some other stuff!) I can only assume that Sprint have had this thing so locked up, even ADB can't help! Any ideas?
