Hello! I was messing around with key combinations, and I found that in the default android recovery on this phone, you can enter a Fastboot mode, and ignore the download mode that samsung phones traditionally use. I can't seem to get it to communicate with my computer, and I was wondering if it would be of any use to unlocking the bootloader on this device.
Fastboot mode is a way to unlock the bootloader.
Download mode and fastboot would be the same thing
fastboot oem unlock does this same thing
It would be nice for a picture though.

I am unable to enter fastboot mode. I have tried all the adb commands and holding the buttons but it just reboots like normal. I have Allow OEM Unlock activated in Developer Options why won't it work?
Hello, I have problem with my softbricked Nexus 5.
phone is full stock
bootloader is locked
USB debugging is not enabled
Android 6.0.1
all buttons are working
USB socket is fine
Factory reset from recovery mode is not working - still bootlooping
My purpose is to bring it to live, but I am stuck. Due to locked bootloader I have to use LG Flash Tool. Some time ago I used it with my other Nexus 5 and it was fine - worked excellent. Now I want to do it again with other phone but I am stuck on start: Can't enter download mode (volume up+usb cable). When I am trying to enter to download mode,charging battery icon appears and after few seconds my phone is being recognized as MTP USB device in device manager. I thought it is a problem with the phone, but tried with another working Nexus and there is no difference - it looks like problem with phone-pc connection to me. I tried few cables (original samsung and nokia) and two pc's - no difference. Tried all USB ports etc. Clean reinstall (with registry keys delete) doesn't help, updated version 4.2 neither. Do you have any ideas how to fix it?
Download mode? Never heard of that on the Nexus 5. There is a fastboot mode for flashing stock ROMs and to unlock the bootloader.
I recommend unlocking the bootloader and using NRT to flash a stock ROM.

I have NRT but problem is that to unlock bootloader I have to enable USB debugging - I can't do it with bootlooping phone.
Bootloader can be unlocked without enabling debugging as you are not running adb commands, you need to run fastboot commands.

Thanks! Can I do it with NRT also?
Easiest way to unlock the bootloader on a windows machine is to do this:
make sure that the necessary fast boot drivers are installed;
boot phone into fast boot mode by holding down volume up, volume down, and power;
connect the phone to the computer;
type "fastboot oem unlock" without the quotation marks and press enter key.
Unlocking will wipe the phone.
Once unlocked, you can flash a stock ROM using fastboot commands.

Ok I did it. Do I have to proceed "fastboot reboot" command? when I am doing it it reboots and still bootlooping. When I enter bootloader it is locked again
If the bootloader relocks itself when the phone is rebooted, the memory chip is damaged and will need a motherboard replacement.
Fastboot Mode
prodcut_name - sdm845
variant - sdm ufs

fastboot oem unlock FAILED (remote: `flashing unlock is not allowed
fastboot rerror command failed
the windows device manager i installed google android bootloader interface because i cannot install the oneplus specific driver it exits with error message
I cannot go to recovery mode from fastboot nor change any setting like enable oem un-lock or usb debbuging option
Any chance to unlock and flash the with new image
Enable Oem unlocking in developer options
@Tab E mercy but i can^t exit out of the fastbood mode to chagne the settings i`m locked inside this bootloader mode and cant do anything else but try with fastboot oem unlock...
Try
Code:
fastboot devices
fastboot reboot
@jwoegerbauer the commands work the oneplus is rebooting into the fastbood mode again i need to exit the fastbood mode because maybe the os deleted and can only use fastboot mode to flash it or else i dont know how to exit the fastboot.
I don`t know if developer mode is on or if oem lock is unlocked but since i cannot go back into the oss of the system what can i do to recover the device completely
i`m stuck in this fastboot mode and no commaand is helping to get out of it what is the solution_maybe to take out the battery it is really hard have you had the same issues?
Whether phone should run in ADB mode or Fastboot mode or Recovery mode or ADB Sideload mode is set via a kernel flag read by bootloader when phone boots up. Pulling out phone's battery doesn't change this flag.
Typically to boot Android in NORMAL mode you run
Code:
adb devices
adb reboot
I tried every way possible to enter fastboot mode but I can see only a brief moment of Chinese words then my phone reboot with no sight of fastboot mode
I really want to root my fast but only problem is that I can't enter fastboot mode
To root a phone's Android Fastboot isn't needed at all: Fastboot deals with phone's bootloader.
Hi, i am loading booting to bootloader from adb with commnad (adb reboot bootloader) this isnt working, only restart its instantly switch to normal os, any ideas ?

Unlock bootloader if not done yet.
where i unlock bootloader ? In developer settings ? (i have unlocked)
Enabling OEM Unlock in Developer options doesn't unlock the bootlader, it simply prepares the bootloader to get unlocked via fastboot command.

Only I have a small problem I don't unlock my bootloader via fastboot when it doesn't work :/ It immediately jumps to my system when I boot fastboot, even with a command like ,,adb reboot fastboot"

I don't know if you are still interested in accessing Fastboot but you can access it using a specific firmware version.
Still, let me tell you that unlocking the bootloader is virtually impossible. Since the well-known generic method doesn't work for the SoC SC9863A, you need to have a special Fastboot's program version and a dedicated private key that only they provide.... and I emphasize the word "dedicated" since apparently ZTE did not use a generic key to sign their ROMS. At least on this device.
Unless they decide to release the key or give support to unlocking the bootloader, all we can do is wait for them to change their minds. Because they don't want to provide it. I know because I tried to order it several times.
