fastboot oem lock
Thats the command.
Use power + vol down
Or
Power + home button + vol down.

It's just that fastboot doesn't work on Samsungs.

Actuallllyyyy just use odin or heimdall to lock it.
They both have options to lock your bootloader your device would be wiped

[Q] help fastboot mode

i flash my device 2.1 + fastboot. but i cant enter fastboot mode with these combination camera + power. i know that my phone has a fastboot mode. because there is a weird thing happen, it enter fastboot mode even i did'nt hold the camera and power button, i just plug my phone into my computer, and now i cant enter fastboot anymore. any ideas?
flash it again, try another ROM

[Q] Can't go through boot animation in any rom

Hey guys, I had Lollipop 5.0 and I did stock rom flash in Nexus Root Toolkit to install 5.0.1, everything went smoothly and it started to boot, I waited for more than 20 minutes. Then I decided to do it again and it was really hard to get into fastboot, I had to disconnect the battery and try for some more time. When I finnaly get into fastboot mode I have tried reinstalling 5.0.1, installing 5.0, 4.4.4 and even Cyanogen's last nightly. With any of those I had no luck as it is stuck with boot animation.
Some googling told me about people who did fastboot oem lock and it booted up, just tried that with no luck also.
One very important thing, when I get into fastboot mode, I can only select Start in the device itself, clicking volume up or down doesn't give me any other option.
Edit: I even downgraded Nexus Root Toolkit from 1.9.9 to 1.8.2 thinking it was the problem, no luck. And tried to install Lollipop manually a couple of times. And the problem trying to get into fastboot mode keeps happening.
Thank you all in advance
And now that I tried to lock the bootloader I can't unlock it again because when I go to fastboot mode I can only press start, pressing the volume keys doesn't do anything. What can I do to unlock the bootloader ? I think I'm stuck in here because I can't do anything else without it unlocked.
Edit: It didn't work to boot the system also
I really need some help here
so your volume down key is working when you're entering bootloader mode, but after "fastboot oem unlock" command you can't choose "YES" with the same volume down key ?

All my keys are working just fine, I can easily boot into bootloader (I was doing Power + Volume Down when I should push Power + Volume Down + Volume UP) but when I get into bootloader/fastboot (I don't know which one is the proper name) I can't do anything but press the Power button, meaning that I can only choose START. When I do the fastboot oem unlock command I can't press Volume UP or Down to choose Yes.
I followed this tutorial (http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060) with no luck aswell, I finnaly got into the system, but I can't unlock the bootloader because of the Volume keys problem. I also noticed that even when I'm into the system from that tutorial, which is Jelly Bean btw I still can't use the volume keys.
Basically, phone only recognises volume keys when it's off and I press to go into bootloader or download mode.

Fastboot mode not working?

Hey all! Got a quick question for ya. So the key combo to enter fastboot mode is volume up and power right? It won't work for me and I'm not sure why. When I press volume down, recovery mode works just fine, but trying volume up boots OxygenOS normally. Using advanced reboot from developer options can put my device into fastboot mode, but key combo won't work. Suggestions? Thanks guys!

adb reboot bootloader
Edit: I just tested it out on my TMobile variant.
Power + vol down (this is the typical button combo)
It then asks for my pin. Then asks for language. Then its the recovery mode. Asks to wipe, clear cache, or boot into fastboot.

That's exactly how mine works! Volume down takes me into recovery, which has an option to reboot to fastboot mode, and that WORKS! But holding volume UP for fastboot mode boots the device normally. Weird. Maybe that's just how these phones work? Recovery first, THEN fastboot? Idk, I'm puzzled here.
EDIT: Might be worth mentioning I bought mine from OnePlus directly. The 256GB storage model.

Found the answer:
To boot directly into fastboot mode, it's vol+ AND vol- and the power button.
All three buttons.

I got my hands on a cheap Ticwatch S2 and i asking myself, what is the benefit of TWRP/root on a smartwatch?
I mean, ok i can make backup in TWRP or flash things, but it seems that there is no custom rom for this model, so root seems to be the only thing to achieve. But what can I do with root on a smartwatch?

Unlock SM-G975F/DS not work [Solved]

I had Problem to finalize the Unlock. After the DEV settings I was not able to reach the correct download mode.
Volume Down + Power = not worked
Volume Down + Bixbi + Power = Not work
Volume Up + Volume Down then Plug USB = Not work
Volume Down + Bixbi then Plug USB = WORKED!
How I solved the Problem
Download IMG files:
https://download.lineageos.org/devices/beyond2lte/builds
boot.img
recovery.img
vbmeta.img
lineage-19.1-20230301-nightly-beyond2lte-signed.zip
Use Heimdall to flash these images:
./heimdall flash --VBMETA 'vbmeta.img' --RECOVERY 'recovery.img' --BOOT 'boot.img'
Unplug USB
Press Volume down + Bixbi + Power until screen went black
Imediately switch to Volume up + Bixpi + Power and hold it until lineage OS Recovery appear.
(Ignore the unlock warning)
Activate ADB
adb sideload lineage-19.1-20230301-nightly-beyond2lte-signed.zip
