Unable to boot into fastboot mode (download mode). - Android Q&A, Help & Troubleshooting

Hi, in currently using a Samsung Galaxy A7 2016. I wanted to boot into download mode, so I tried the respective key combinations. However, the phone just boots back into the OS. I even tried using the adb command "adb reboot bootloader" but my phone just does a normal reboot. I have already enabled OEM unlock. Does anyone know how to boot my phone into download mode?

Hi:
My unlocked bootloader SS2 phone got stucked in Download Mode after successfully installed/flashed AICP ROM
It booted once and when i rebooted to enter recovery got stucked. Tried pushing buttons combos but still stucked in Dmode.
Have no access to fastboot from Windows but can get limited access to fastboot in Debian: can flash several twrp recoveries, can flash
AICP ROM again but can not get fastboot oem commands working.
Can't enter to recovery because phone never turn off.
Tried also to come back to Nougat but can't enter recovery to flash ss2_old_bootloader.

I also have problem after flashing to AICP and sometimes phone (after power off) stuck in Download mode.
Just enter:
fastboot --set-active=a reboot

I have the same problem. I tried to follow your advice, but fastboot in my PC doesn't recognize the parameter (all I get is fastboot help page).
Regards.
EDIT: reinstalled treble v3.1 via OST and it fixed the download mode issue.
thanks!

in my xperience is connect your phone to the PC then open cmd ... make sure in folder of adb and fastboot .exe stored ...
type:
Code:
fastboot continue

Maybe use other fastboot.
Sometimes you must enter:
Code:
fastboot --set-active=_a reboot
("_a" instead of "a")
BTW. My Aquos sometimes stuck in download mode after installing AICP.
I fixed this by entering:
Code:
adb shell
bootctl mark-boot-successful
Hello, i have the same exact problem. I tried to use adb program to fix this problem, but my laptop couldn't recognize my device. Any other solutions would be helpful. Thanks for your attention! (I'm a beginner in technology, so please forgive me)

[Android] Honor 8 Bootloop - only get into fastboot

Hi,
yesterday my Honot 8 worked fine. THen in the night it began with a bootloop, so that battery can't be loaded anymore. Now only possibility to switch it on is put a cable on it. But there is a bootloop, so that Android is starting with boot image and restarts after some seconds.
I can't get into recovery mode (Vol up + Power). Only get into fastboot mode.
Phone Locked
FRP Unlocked
IN Windows 10 i get access to fastboot.exe and the device is recognized. COmmands like "fastboot erase cache" doesn't work -> remote command not allowed.
Any chance to get it run again without factory reset? What can i test now?

Huawei Nexus 6P unlock download mode in bootloader how?

Have decided to root my phone with Adb and fastboot devices in Windows 10 and also installed drivers sucessfully and i can se my phone in cmd when i type fastboot devices.
Have unlock the bootloader in the phone and Enabled USB failure search in Advanced settings in developers mode.
When i loaded the Twrp file in cmd with adb i could copy and write the file to my fastboot device but when i reboot the phone into bootloader i se that download mode are disabled.
How can you unlock download mode ?
When i try to reboot into recovery mode i get the Android bot with a red triangle into it.
Im guessing that happens for i dont have download mode enabled and im wounder is the Twrp file on my phone or have that setting stopped this process?

ADB doesn't find Samsung device in recovery mode (and else)

Hi!
I'm still on my way ro root my Samsung Tab SM-T725, after upgrading to Android 11. Before Android 9 was on the device, succesfully rooted via Magisk. Updating and keeping the root status didn't work properly, the flashing process in Odin failed. Therfefore I had to flash the latest stock recovery, successfully. So now I have Android 11 on my device but no root. The bootloader is open and USB debugging enabled.
I tried the method described here. But the flashing in Odin failed again. So now I try to follow the instructions on the Magisk website. If I get everything right a processed recovery.img has to be flashed via ADB/Fastboot. That's new to me and I have questions.
- Is fastboot and download/recovery mode the same? Booting to the recovery and following "reboot to bootloader" leads to the turquois "Downloading" window. The same occurs when prompting "ADB reboot fastboot" e. g. Again the mentioned Downloading window shows up, nothing (special) with fastboot. Is that correct?
- Will therefore all fastboot commands not work? And only ADB is possible on my tablet? Is that common for Samsung devices?
- Can the flashing of the patched recovery.img (for Magisk) be done with ADB as well? Instructions always mention fastboot.
- My device doesn't show up in ADB when being in recovery mode. In normal mode it is listed when entering "ADB devices". Trying again in recovery mode the list stays empty - and all other commands have no effect. Current Samsung and Google USB drivers are installed. How could that be solved? Without ADB (perhaps fastbood) running in download mode I shouldn't be able to flash (and root the device) as planned.
I hope I described everything properly. I'm not that Android expert - but successfully managed to root a couple of devices over the years.
Samsung devices dont know of Fastboot mode. But you can run them in either Recovery or Odin / Download mode or Normal mode.
Running Samsung devices in Download mode you can flash ROM or update system in the Android device. When the Samsung device has entered Download mode, the device will boot from external sources. You can also make the stock ROM replaced in Download mode.
ADB mode is the Normal mode.
In Recovery mode ADB - with some exceptions - isn't working
Because your device is a Samsung one the Google USB drivers are senseless. Remove them to avoid conflicts.
Thanks for the quick and helpful response!
That makes clear why the tablet didn't show up in ADB. And that all rooting efforts for Samsung devices via that way should be obsolete. Strange enough that Magisk doesn't mention this on their instruction site.
So I'll have to try on with flashing a patched AP via Odin - and hope for a solution for my fail-problem.
