It's possible to enter fastboot using "adb reboot bootloader" if the system is up and running and you have ADB.
However:
Has anyone figured out how to enter fastboot via a keycombo on power up?
VolDn sends you to recovery
VolUp (which was fastboot on the Find5) takes you to some sort of factory mode.
https://plus.google.com/101093310520661581786/posts/F1LKcuN5RVV is a screenshot of factory mode - does one of those happen to say fastboot (for those of you who read Chinese)?

Can't find a way to enter fastboot...
On another mtk6589 device (wiko stairway), you need to hold vol down and up and then start (power on).

Hi Entropy i have Oppo r819 and got bootloop and no fastboot. Have you solved? Cam you help me? Please
since yesterday i was not able to enter recovery mode. If i press vol up+ power then i can enter bootloader. but when i choose recovery and press the power button, it just reboot the device and enter bootloader again. the device itself is working fine, but i can not ota update
Same
I finally got around to going through the root/bootloader/recovery/rom process, only to get stuck at this exact problem. Rooted and unlocked bootloader just fine, no issue flashing the recovery via fastboot until I actually try to load into recovery mode for the first time. Exact same experience, loads in to flash boot mode, reboots when I try to select recovery mode.
Someone help! I want CM13!

Were all the same problems facing rightnow. I recently flash the stock recovery and it turn to endless bootloop. Does one of us already fix the issue ? I can't boot to fastboot.
Theres only one left chance of reviving damage of phone software. JTAG is the best option . But JTAG is expensive. Better go to nearest cellphone shop and pay their fees.

i bought the phone unlocked and rooted with magisk but i accidentally formatted the phone and now magisk is gone
bootloader is unlocked
i can enter into download mode and stock recovery but not fastboot/bootloader mode(restarts whenever i try to do so).
tried both physical combination or adb reboot bootloader,same result.
software version g710n20c
model number lm-g710n
I didn't made this tutorial, all credits to user 机锋网友8051_ABD

You will only have fastboot on Samsung with custom rom and stock custom rom recovery. Like if using LOS you have to use LOS Recovery for fastboot to work. TWRP does not support fastboot mode on samsung. If still on Samsung firmware there is no fastboot it uses Odin.
