[HELP] Unable to enter Download Mode - Samsung Galaxy M31 Questions & Answers

Hi,
I unlocked my bootloader and and am trying to flash the android 10 firmware via odin but when i try to boot into Download Mode it asks me to press the power button to continue and when i press it the device boots into android instead. The prompt to enter download mode stays for very little time and then android boots. My firmware is the latest INS version with android 11. Please help experts.
Thanks in advance.
EDIT : I posted this during a panic attack lol. Everything is working for me. Admin please delete this post.

http://forum.xda-developers.com/showthread.php?t=1637966 - its written that you go in download mode and open odlin , how is this possible ? when phone is off and you can open any app ?
bump.....still need this help
Im guessing this is the first time flashing/rooting. Take your time coz what your playing with can mess up your phone.
Firstly, to put your phone in download mode. Do this by:
-First switching your phone off
-Now hold down these buttons at the same time: Power button + Home button + volume down button
-Hold them all down till you see the yellow triangle icon
-Once u see that, your in download mode
Now its important to follow the steps given in the guide about using Odin
nvm its rooted now , i found out that odin is a windows app not android.
Thanks stil..

Odin doesn't detect my device / CM9 update fail

I tried to upgrade to CM9 (before on 2.3.3) on my GT-P1000 but when i Choose the zip from the sdcard it directly boots with CM9 startup screen and reboot again and again.
Please Help me! I can get to Download Mode but Odin doesn't detect my device (I think that's because of zadig).
I'm begging you please help me (even to get back to 2.3) i'm out of phone now
PS: I followed instructions here : wiki.cyanogenmod.com/wiki/Samsung_Galaxy_Tab_(GSM):_Full_Update_Guide
probably the well known boot loop?
Did you try booting to recovery and flash one more time?
OMG thank you so much i pressed on the power button and the volume up button at the same time (where as i must press the volume up later) that's why i can't get to recovery mode
You saved my life thank you!! :good::good::laugh::laugh:

Extract the zip file I added to the folder and open the Frija software. Download your firmware by entering the version and model of your device and the code of the country where the device is registered. Copy the AP file and paste it on your device. Open magisk manager app and tap install. Patch the AP file. When the process is finished, you can transfer the tar file named magik pacthed in the download folder to the AP section via odin, the file starting with the BL you downloaded with the Frija software, to the BL section, etc. Select HOME CSC in the USERDATA section, if you do not want your information to be deleted. Turn off your device, press the volume down, volume up and power button at the same time, and when the screen turns black, remove your finger from the power button and put it into download mode. Before starting the installation from the Odin software, deselect the Automatic Restart option in the Odin software options section and try to Start. When you get the AVB (fail) error, press the volume down, volume up and power button at the same time, and when the screen turns black, remove your finger from the power button and enter the download again. Deselect the AP partition, click Start again and wait. After installing the device, disconnect the cable and install Magisk Manager, if it does not stop. reboot if prompted. and now your device is rooted.

Stuck in twrp logo note 9

Hello,
I have flashed twrp over Odin and it works well, flashed custom room too, everything was super fine but after i restart the phone
Got stuck in twrp logo
Can't go to download mode or boot to system either.
Tried to hard restart power + vol - then after restart press power vol - bixby but same issue.
Download mode won't launch neither recovery.
Picture of the problem in the attachment
Please any solution?
first you flashed the wrong version of twrp according to your attachment, in my opinion you have to reflash everything and you can follow this tutorial and I hope it helps you

Sorry but i don't think it'll boot first time or even i could flash custom rom from it if the recovery wasn't compatible.
After the twrp everything was fine, and i got access to twrp recovery and flash custom room without any problems.
First bot was fine, but after 2 consecutive restarts
This issue occurred .
And can't make it to download mode now, so I can't flash stock or anything.
I mean the correct version to flash android 13 it is twrp v 3 7 0 9 0 if not the phone hangs at twrp logo.
now to put back on download mode you have to do this manipulation
1/ connect your phone to your pc with the USB cable then press bixbi and power (between 5 and 7 seconds) and when the phone goes black at this moment don't let go of bixbi and power you have to press the volume button -
I hope it will go.
