S8+ can't open download mode - Samsung Galaxy S8 Questions and Answers

Help me please!
I'm doing the process to open download mode and it boots in test mode, when I try with Volume Up button, it only appears 3 options: fastboot, recovery, reboot.

If I remember correctly, it's Bixby + Volume Down + Power Button

Grand Prime Duos stuck on TWRP

Hey, I really need help.
I was about to reinstall my OS (I was currently running 5.0.2 (G530HXCU1BOI2 to be more specific).
I proceeded to reboot on recovery mode to wipe as usual (I use TWRP 2.8.7.0) but this time I tried the format tool. But something unusual happened: I can't access bootloader to install my clean ROM.
I tried to reboot to Bootloader on TWRP but Odin doesn't detect it. (It's like the bootloader but without the Android logo. Instead, it shows the brand and name like a normal boot)
What can I do? is it hard bricked?
P.D: I can still access recovery, only that.
P.D.D: I tried to get to bootloader with Vol up+Power buttons but it doesn't work. This brings me back to recovery.
EDIT:
If someone can make a recovery file in order to make the phone to boot, it might help.
Power off your phone, hold Volume Down and Power key, when a screen appears to confirm press Volume Up, now connect to PC/Odin
It does not work?

[General Info] Entering recovery mode on the Redmi 3S

If you flashed the twrp recovery image from http://xiaomitips.com/guide/how-to-flash-twrp-and-root-redmi-3s/ and cant boot into the recovery using vol down + power ( which is basically fastboot ) or the volume + up ( which is just booting into rom )
To boot into your TWRP Recovery or any other recovery that you've installed
1) Power off your phone ( Don't have any cable connected to it )
2) Volume up + Volume down + power button and hold
3) When you see the Mi Logo appear , Let go of ONLY the power button
4) If you've successfully flashed the twrp image on the recovery, you should be entering twrp mode now.
5) Disable dm-verify from advanced settings.
You're done :good::good::good:
The only reason i made this post was for all the android phones i've used, volume down+power button meant going into recovery mode, and not fastboot mode. this was the first phone with different key mechanics and I thought you guys should know as well
TL;DR? Volume up + volume down + power = Recovery
Volume down + power = Fastboot mode always
Volume up + power / Power button = Normal boot
Great information ??

Your method works not every time. From time to time its different.
Here is what for me works.
WITH OPEN BOOTLOADER
I flashed TWRP with Fastboot
fastboot flash recovery recovery.img
>>>directly after flashing<<<
1.) Push Vol+ and Vol- and Power at the same time
2.) If you see the MI-Logo release ONLY the Powerbutton and wait
3.) With a little bit luck you are now entering TWRP
4.) If not, do not release Vol+ and Vol-, the Devicescreen went totally black
5.) Do not release Vol+ and Vol- and push now the Power Button
6.) If you see the MI-Logo release ONLY the Powerbutton and wait
7.) Then TWRP starts (for me)
8.) A few times i landed into the chinese menue, then push the recovery button, with a little bit luck you arrive TWRP
9.) If nothing helps, and the device starts normally, imho the process changes twrp back into the original recovery -- then flash twrp again and start from Point 1.)
NOTE!! If you enter TWRP the first time go to Advanced Settings and tap on --Disable DM-Verify-- .
After i disabled DM-Verify and flashed the Xiaomi.eu Rom the above worked for me without every time flashing twrp.
I worked 6 hours at this workaround

Glad buddy
Thanks, OP.
Just would like to confirm that disabling DM-Verify option does not make the phone go into Recovery/Bootloader mode via Advanced Power Options menu while the phone is ON.

Right after having flashed the TWRP trough fastboot you have to do the following:
- Keep pressed power+vol- buttons until the phone turns off
- Immediately after the phone turns off keep pressed power+vol- until the LG Logo appears
- When the LG Logo appears leave the power button (keep pressed the vol- one) and immediately press again also the power button and keep pressed both until the hard reset mode appear
- Confirm with the two "yes" and if the TWRP is installed correctly (the phone MUST NOT boot into system, if it happens you have to flash TWRP again) it'll boot, otherwise it'll perform an hard reset
Good luck :good:

Thank you very much, I did not realize the second restart that the phone does after unlocking the bootloader, thanks. By the way to open it again I have to repeat it, (instal twrp and then open it) or I have it fixed?

If you flash SuperSu or Magisk you're good to go, otherwise yes
