Can't access service mode on HK version - Samsung Galaxy Note 20 Ultra Questions & Answers

Hi Guys,
Sorry, too many posts today!
I want to wipe the cache partition but unable to access service mode on HK Note 20 Ultra.
I turn off the phone then press up and power keys simultaneously but it just boots up the phone without entering service mode.
Is there any other key combination or should I enable something on the phone to access it? Thanks.

Apparently since the September update the. 9860 can't access via button presses. ADB only.

Try plugging the phone to your computer first then do the buttons (volume up and power}. This works for me

[Q] Can't use power button to unlock phone via HTCDev

Hi everyone,
I'm trying to flash a custom ROM, and every method requires me to unlock the bootloader via HTCdev, but I have two problems:
1) I can't boot into bootloader. When I hold power + volume-down, the phone boots into safe mode (I don't think that's normal right?). I took care of this by using adb and (adb reboot bootloader) to get into the bootloader.
2) When I'm in the bootloader, the power button (to make any selections) doesn't work. So I'm always stuck at the last screen that says "Unlock bootloader?" and I just have to select "yes" with the power button, but I simply can't!
Does anyone know how I can get the bootloader to work normally, or get my power button to work when I'm in fastboot?
Thanks in advance!
Did you get around this? I keep having the same issue!

Read the screen on your phone , you got to use volume up or volume down button to select yes or no , i think volume up is for yes and than press power

Maybe certain fastboot commands may help a little, if the power button is damaged. (Maybe take off the back cover and see if you can then push it down properly..)

And not exactly.
If I recall correctly,
vol down means moving down on the list
vol up means moving up on the list
& power button is 'select'

When you are in that screen that i showed you, what happens when you press Volume up , does it select on the scree YES unlock the bootloader (may avoid you warranty) ? If yes it select's than press power button to continue... and you will unlock you bootloader if not i don't have anything else on my mind :/

Volume up works but the power button doesnt
I'm also stuck in this screen for the past week, I got this phone for free, but now I want to root it but I'm stuck in this screen. I've tried several tools like kgs1992utility, hasoon2000's utility, even the windroid tool for htc sensation, but somehow I simply cannot get passed this screen. Is there any adb commands to replace the power button to select?
only the volume down button works, but it works in the opposite way(ex volume down actually takes you up not down) -__-
cant finish power button will not select yes
I am having the exact same problem the power button suddenly will not work on yes but does on no WIERD and very FRUSTRATING

So I had the exact same issue. I pressed the power button and volume down together and the phone rebooted back into the bootloader, this time it says *** UNLOCKED*** at the top of the screen.

[Solved] Can't Boot Into Recovery!

I have an S7 from AT&T. I'm not bricked or rooted, only debloated. Amidst all this debloating, I fear I have disabled something which recovery mode requires to work. I hold down the power button + volume down and I'm put into a loop of Samsung logos.
Does anyone know what needs to be enabled for recovery to function? Here is a list of everything I have disabled:
It is not "asurion.android.mobilerecovery.att", that is an AT&T recovery app.

send me the photos on this +91 9023564990
Finish the battery power of the phone and leave it for 2 days or so (in Download mode and *not* connected to odin) for faster battery usage, or anywhere as long as it on
After that power it to recovery mode with the volume up button and the power button but press em right after inserting the power cord (cable to your phone to charge it so it can boot to recovery)
When the Samsung thingies pop up release the power button and don't release the volume up button
Press till u see the recovery menu and then wipe cache and then factory reset it :cyclops:
Mostly likely it's gonna need the previous Google account details, I'll research on how to frp bypass the Google lock

You can boot into recovery without having to plug into a computer by holding power + volume up, and then once you get to the "this device is unlocked, press power key to continue" screen, rather than just waiting for that screen to disappear, press the power key and then you should be taken to recovery... at least, that's how I was able to do it

Ah gotcha, that makes sense, I've never been able to get recovery booting via power + volume up, until I randomly tried pressing the power button at the device unlocked screen, and for some reason doing that took me into recovery

Are you powering off your phone first? If so wait a few seconds after then hold down both power + volume up buttons at the same time and hold for 10 seconds. It still works for me doing it this way.

This works like a charm. I was about to give up my phone because of this predicament, I didn't want to have any issues restoring my phone in the future in case. THANKS A BUNCH!
It's kinda strange but it is bootloader issue. I am on BTK3 firmware (latest Android 10 release) and i'm experiencing such misbehave of key-kombo to enter ot recovery mode since September or October FW update. Has jus tried to downgrade bootloader to initial firmaware (ATGM) by flashing BL in odin and now i can enter recovery by only pressing vol-up + bixby. It work always. Cables, headphones... nothing needed. just keys-combo.
Then i tried to update BL to latest Android 10 (BTK3) and again recovery mode doesn't work. Only if N9860 connected to PC by cable and even with that it doesn't work for me 10 out of 10 times.
Can someone text/call Samsung support to report this issue ?
BTW thanks to @Mentalmuso for helping me!
Same things happen to Android 11.
Tried to flash on my N9860 old BL over Android 11 firmware (was installed before that, all files AP, BL, CP, CSC), flash was ok, but system was unable to load. constantly bootloops. but i was able again to enter recovery without cable and etc. Tried to wipe cache and factory reset from default recovery but no luck - bootloop.
I thought that game over and old BL is not compatible with new android 11.
But then i wanted to try do the same but with custom binaries (@Mentalmuso TWRP and kernel) and ta-da - system loaded from the first try. For me it's surprise. Now i have Android 11 latest FW for TGY (CUA3) with initial BL from the box (ATGM) and everything looks like working fine. No error in OS, no random reboots (at least after 30 minutes of test) and recovery can be simply loaded only by key combo, without any cables, headphones and PC.
I'm happy now =)
Strange thing is that after fladhing old BL system did not show error message that vbmeta changed and some error in vbmeta header. It was showed always on Android 10. But i flashed twrp again (it has vbmeta inside .zip) to be safe lol.

Question I can't access the Recovery Mode

Hi,
I do own the S22 Ultra Exynos with 12/256 GB Memory,
I already tried several times to access the recovery mode to wipe out the cache partition
( powering off the phone, holding the power button and the volume down button and releasing both
as soon as the logo appears) but it doesn't work...
Anyone having the same trouble ?
Kind regards,
Valy

Try volume up (+) & the power button.....
I already tried that too, doesn't work either...
In the good old days, you used to have to have a usb plugged in to access recovery (and at one point actually also be in a recovery programme on a pc, or use a hacked together usb jig to do it on the fly). I would be surprised if they have gone back to that, but might be worth a try?
Turn device off,
Ensure one end of your USB Cable is plugged into the PC / Laptop
Press Power + Volume up
While you press both Power and Volume up insert the USB Cable into the phone.
Keep pressed and you should enter into the recovery, You used to be able to do this without the USB Cable, but recent changes made you require to plug it into a device.
Unsure if you can do this using a normal wall plug, i have never tried it.

Maybe it's an Exynos issue, I just booted into recovery with the volume up & power button combination (no plug-in of cord needed) on my Snapdragon-powered S22 Ultra.

update?
Hi All, - I had the same problem, it would just not go into recovery mode. however a slight twist i saw on a website says to do the following and it worked first time much to my suprise..
basically the phone has to be powered on to start the process..
1.HardReset.info: At first, connect the device with the computer by the USB Type C and push Volume Down + Power button to switch off your phone.
2.HardReset.info: Then press Volume Up and Power key for a short while.
3.HardReset.info: Let go of all buttons if you see the SAMSUNG logo
4.HardReset.info: Now use Volume keys to select Wipe cache partition and confirm with the Power button.
5.HardReset.info: In the next step go to Yes option.
6.HardReset.info: At last, choose Reboot system now by using the Power button.
good luck..

Hello.
That only works with the included USB Type - C cable. It doesn't work with a USB type A cable. Both ends should be Type C.
That's why it didn't work for me earlier. I tried numerous times using the old cable from my Galaxy Note 9.
