Stuck at entering fastboot mode

[repoman_1966]

How can I get my Galaxy Note 20 Ultra out of stuck at 'entering fastboot mode'?

Hold down power and volume down until it reboots back to recovery. I got stuck there last week and that's what worked for me.

Is this problem solved? I cannot boot into bootloader mode, thanks!

Switch off the device. Then hold volume up and down buttons and insert the USB cable plugged to PC. You will get to download/odin mode

Download mode is different from fatboot mode, I can enter, and works ok download mode. However, fastboot does not, it gets stuck in entering fastboot mode and no fastboot command works

I got same issue here, I've tried rooting via TWRP and after data wipe and "reboot to recovery" it got stuck in same thing and doesn't move at all, if I hold power and vol down it just boots the device which i dont want since i need to flash magisk as a last step. if anyone encountered this or knows how to fix it i'd be helpful

I'm not rooted but I've had past Samsung devices that I was able to root and if I'm not mistaken Samsung phones aren't able to boot into fastboot mode because Samsung removed the ability to. You can run commands via ADB mode but I think that's about it

Guys, turn off the phone, press volume up and volume down together, and plug the usb cable while pressing volume up and down, and wait until the phone enter in downloading mode. This work for me.

Since we can"t enter into fastboot mode is it possible to flash boot.img with adb commands?

I m having the same problem with a21s(a217f). I can t enter download mode using key combinations and the other way launching it from recovery doesn t work, it stays stuck at,, entering fastboot mode,,
The ROM is already bricked, it says in recovery when i try to factory reset the following error:,, can t mount. /system (structure needs cleaning)
Even with,, apply up. with adb,, doesn t work, it just doesn t get detected on my computer when i checked with adb tools.
! The only thing that works is that I can access my sd card and apply a update from sd card but I don t know where to get the update file. (I ll edit if it works to flash stock rom from,, apply update from sd card,, )
Anybody got some ideas or should i burn my motherboard and replace it?
sorry for bad english

Honestly plug device into PC.
Power off device
hold all 3 side buttons. Volume up and down and power/bixby.
Should usually work.
After in fast boot you must press a button Volume button to find via odin.

I already did that, unplugged the battery, reconnected it after 1min, connected my phone to the computer and pressed all 3 side buttons, still doesn t work. I guess the download mode is deleted or something..

Volume up & down, no side key, then connect to PC. Works for me. Connect to PC first does not work for me.

It wouldn't be deleted as it's a safety protocol if the device has a bad update and freaks out.
Maybe try to person above method.
Normally I can enter download mode with any of these methods if you cannot I'd suggest trying to get the device replaced due to software malfunction

Samsung phones use a tool called Odin to flash firmware. If you're flashing custom firmware firmware you'll need to have your bootloader unlocked.

I got mine into download mode just now. It's a Galaxy A13 .. Like stated above, try to hold all three buttons down and connect to USB. I had to let go before it showed the battery charge icon. From off. If not from off try from charging. I think that's what I did just now. Plug the usb -> let it show the charging icon (from powered off!) -> hold all three buttons, let it power on, let go. DONE.
