I've got att S20 ultra and can't access either download mode or the recovery mode, no matter what I do.
I forgot the pin code and can't reset it.
Tried vol up + power, but phone just boots up.
Pushed vol up and vol down with usb cable, but still same,
Any ideas?
Anyone?
Easiest option if forgot yr pin is to go to Google find my device on a computer login with your Google password registered to that locked device and erase the phone from there. Odd u cannot get into recovery maybe att locked that feature?
I have no problems with entering recovery using vol up + power.
It's easiest to do it after a restart where you press the buttons immediately after the restart has started and keep pressing until recovery shows up.

I was provided this device to try and help resolve the issue. I am not sure how it got to this point. I believe that it was rooted with a custom ROM, then the individual tried to install a stock ROM (method unknown).
The current situation is:
Galaxy Tab S 10.5 SM-T800 stuck in a bootloop with the TWRP logo on the screen. I can not get the tablet to go into download mode. I have tried all of the different methods to enter download mode, i.e. Power & Vol - & Home, Drain the battery > Plug into PC while holding Vol - & Home, Power & Vol + & Vol -. None of these combinations do anything. The only thing I can do to get a response is to press Power & Vol +, which reboots the device right back into the TWRP loop after the Samsung Logo. Power button alone does nothing.
The device is seen by Windows with the Samsung Drivers but is not mounted to a drive letter, and I can not mount it.
ADB , fastboot and Odin do not see the device.
I would like to flash a new rom either custom or stock, but I need to be able to get the device into download mode so it can be seen by odin.
Any help would be great.

Probably just timing and pilot error this one. I've never known of any Samsung device boot but be incapable of booting to download mode as download mode is bootloader related.
No working bootloader means dead device.
No matter what state the device is in at the moment with the usb cable removed, hold POWER + VOL DOWN (not up) + HOME until the Samsung boot logo comes up, hold for another couple of seconds then release. Download mode should appear.
I know it should be easy....
I know it should work but it is not, I will make a vid of the process and post. I can not make heads or tails.

Is the home button actually working, are you pressing it firm enough?
If the home button doesn't register then the tablet will simply reboot.
Its a bit odd why twrp doesn't fully boot though unless it's the wrong one.
Does it hang at the twrp logo or continually reboot?
Hey, i have j6 and i forgot the screen code, so i tried to flash a stoxk rom but i cant enter downloading mode, i tried to plug the phone to computer and hold all buttons but still nothing, i can enter recovrey mode, of curse the easy way its to do wipe data but i cant because its blocked by mdm and again i cant enter my phone. There is some way to get downloading mode ?
Power off your phone. Hold vol up and power button . This will bring you to recovery mode. Then there you'll see the option to reboot to bootloader
Hi folks
Anyone seen this issue before (see pic) ?
When I try to enter download / bootloader mode I get stuck on red text 'entering fastboot mode... ".
Odin cannot detect the phone connected to PC
The only way out is to press and hold power and volume down for 5 seconds to reboot normally
Tried factory reset and also tried clear data & clear cache partitions in recovery mode.
FYI I'm on O2 UK branded July 2020 stock firmware
With this steps the problem will be solved:
Power Off
Insert cable on pc
Press Vol Up + Vol Down
Insert cable on phone without releasing the buttons
But I agree, the 'old' method does not work anymore, I am getting the same message as the OP.

Amazing worked first time ! Thanks
Is this a very recent change by Samsung? I ran various Google searches but could not find any relevant article on the web or on xda forums
So I have spent hours now looking around for an answer the phone is find my phone locked and I can't remember my pin code. I have done all the tricks with the combination keys.
The usual way to get into Recovery mode is Hold V+ and power until the phone vibrates and you should be in recovery mode release the keys. (Doesn't work)
Iv read that you should have the USB cable connected from pc/laptop while you do the same holding V+ and power button... (doesn't work ether)
and download mode should be very easy just hold V+ and V- plug USB cable from pc/laptop and you should get into download mode by pressing V+. Will only show charging Icon and that's its.
So is it possible to turn off this modes from the manufactor? Or is this a completely new security future? How can you use odin? How can you wipe the cache? If you end up having some issues.
Im going nuts....
No way to get into fastboot ether. So if anyone know why this is happening to me or got any solution I would appreciate it.
Plug in your cable with the phone turned on. Hit Power Off and wait for the phone to fully turn off. The charging logo will show up so let the animation do its thing. After maybe 20 seconds, press Volume up + Power and keep them pressed until you boot to recovery. If the command wasn't recorded in the first place and the phone is still off after more than 15 seconds, let go of the buttons and press them again and keep them pressed until it boots in Recovery

It will not work. How the hell should I be able to cle3ar cache if I got a boot loop ??? They can't just turn off recovery mode mand download mode??? This is so strange even paying for a frp reset but not even he does know what wrong??? Can they turn off fastboot, recovery mode and Download mode on this new phones? Is it because its locked with find my phone? 1 week researching now. It will only vibrate. And my PC cant find my phone anymore worked fine 30min ago nothing has changed... So annoying never seen this happened before every combination with buttons to get in any mode doesn't work only vibrates and go to pin lock screen...
Take it to a Samsung Experience center at best buy. Or send it into Samsung for repair.
download mode:
Turn off phone
plug cable in pc but not in phone
pres "volume +" and "volume -" in the same time
plug cable in phone
recovery mode:
plug cable in pc and s22
power off
press "volume +" and power
wait until see recovery mode

thats a solid advice assuming his bootloader/recovery/download mode is fully functional then this advice works, in his case and in mine too it does not work and trying to get to the root of the problem is the key. In my case recovery mode gives error on screen so it may have to do with the way firmware is installed as these modes are not accessible.
have you sorted it out? Its nearly a year onwards =)

This, at index 2:48 minutes.
It needs to be connected to the PC. Another screwy quirk Samsung added recently. Your button timing/sequence matters as well.
On my N10+'s you can go into recovery directly with a restart if you do it right. Otherwise they will puke on you.
When I was going to root my phone, I must have taken a wrong choice on the download screen (I can't remember what) because it got to another screen like the attached screenshot over this text: "Press power key to continue", but pressing that key does nothing. Every time I start the phone, that screen comes up for about 10 seconds, and then it boots in an apparent normal way.
The same screen of the screenshot keeps coming back when I press the keys for download mode (Volume Up + Volume Down + Power). Pressing the keys for recovery mode (Volume Up + Power, from off) nothing changes. However, I pressed that keys for over 2 minutes and the phone entered in recovery mode. Then, I could wipe everything and rebooted, but the problem persisted exactly as before.
I can't get to the download mode, so I can't download any ROM. What can I do?
Just confirming, you've plugged in the usb cable before pressing the buttons to go to download mode?
Might also try using ADB commands to get to bootloader...
