Unlocking the bootloader on Samsung devices works differently from many others. This is a summary of the steps needed:
Enable Developer Options
Enable OEM Unlocking (if not available or grayed out, ensure device is connected to Internet; if this remains unavailable, unlocking is not possible)
Turn device off and boot to download mode
While in download mode, hold Volume + to get to the bootloader unlock screen
However....Not every Samsung device is bootloader unlockable, especially not in the US. Almost all Qualcomm powered devices are locked, and some Exynos devices as well.

Ah. No, you have to power your device off completely. Then, hold both Volume buttons (without pressing Power) and plug in the USB cable from your computer. The device should start in download mode. Then, hold Volume Up until you get the bootloader unlock screen.

[Q] Too many pattern attempts... No Recovery menu

hey guys
i have a HTC Sensation that is password locked, but the real problem is that it won't enter recovery mode.
the volume down key is working as i've tested it in a "sos call", the volume up doesn't work when the phone is turned, but that's not important as it's not needed.
is there any other way to get into recovery mode?
also, if i hold the up key with the power switch, it boots up in "safe mode"

several times sir, even went as far as draining the battery inside the phone completely, trying it with another battery, leaving the battery out of the phone for a whole day...
are there no usb hacks or something like there is with the samsung android phones?

Are you on a stock rom? if you are the you would have to have un-ticked fastboot from the settings to be able to boot into the bootloader...
try to attach the device to a usb port of a laptop and see if the usb debugging symbol shows up in the status bar. if it does you can use the adb command adb reboot recovery to force a jump into the recovery.

can you take a photo of the pattern lock screen
also what do you know about the device? is it eu,uk,us? also what carrier is the device on? is it on ice cream sandwich or gingerbread? you may be able to run a RUU (rom update utility) on the device, updating the firmware and remove the lock that is currently on the device.
So, no bootloader? When you hit vol down + power it should land you in the bootloader screen, where you then select recovery. Have you tried with the cover, SD, and SIM removed from the phone?

you will need to talk to the owner of the phone, without that info your stuffed tbh. with fastboot enabled in the stock rom you cannot boot into bootloader. without the info like what carrier they are on you dont know what ruu to run to reset the device. without usb debugging you cannot use the pc to send commands as far a i am aware :/ assuming you have the correct htc drivers installed connect the device to the pc, open cmd in your adb directory and type in adb reboot bootloader and see if it responds. again without that info you've pretty much had it. you can try to flash ruu's from the pc at random in the hope that you find the correct firmware and cid, but without usb debugging on there is no guarantee that the ruu will even find it.

yeah, tried the adb reboot recovery, no dice. just error, no device connected.
the owner bought it 2nd hand, so he has no clue, i'm just going to return it. pity that htc doesn't have a "usb key" like samsung that forces "download mode" on the android devices

Any one experience this? tried using power button+volume down but nothing happened. reboot via adb and this happens.

Powering on with Power+VOL Down makes phone to enter in fastboot mode. Nothing wrong... What are you trying to do?
There's nothing wrong here. If you are talking about the FRP unlock, and you want it locked, go to developers settings and disable oem-unlocking. If you want to, you can now unlock your bootloader (factory reset), to get custom recovery, root your phone, etc. (Don't do this if you have no idea what I'm talking about!)

Pixel 2 brick after Uninstall Magisk

Hello,
My Pixel 2 was unlocked bootloader and Rooted.
I went to Magisk app then pressed Uninstall All, then my phone rebooted and brick at boot (Screenshot "No command").
I tried to flash back to stock rom but computer cannot reconize the phone. (I supposed USB debugging was not turned on yet).
Please advise how I can make my Pixel 2 back to work?
Many thanks in advance.

Download and extract the latest version of Platform Tools to a folder, then run all ADB and fastboot commands in command prompt or powershell within that folder. Don't rely on Windows drivers for ADB.

Forget about ADB, you need Fastboot access. While in the bootloader interface, connect your phone, look for it in the Device Manager and change its driver to Android Bootloader Interface, or something of the sort. Next try "fastboot devices" on the command line, see if it detects your device.
I brought my phone to repair shop and they detected that the hard disk was dead.
Just bought another Pixel 2 to have more awesome photos
You have no fastboot I guess.
Boot into fastboot, plug in the usb cable and press and hold the volume down button for like 15 seconds, and then it will be recognized by the PC. You can flash back the stock rom after that.
Hey I had the same problem. Just stuck in bootloader mode. In my case, the boot slot changed itself from b to a (access denied, same as your problem). What I did:
1. I boot my phone, then it'll be in bootloader mode (same as the first picture when it says 'operation denied')
2. I kept pressing the power button, then my phone boot into bootloader again (bootloop). I kept holding my power button until my phone boot into right boot slot. (It took me 10 bootloop to boot into right boot slot, I just keep holding my power button when in the bootloader mode)
You can add my telegram : (@)Djkuns if you're confused. Hope I can help! Goodluck!

Possible or Not? Factory reset bricked Pixel 2.

I've spent hours searching and cannot find a definite answer to my question. I see others have asked HOW to fix this issue, I just want to know if it is possible.
Is it possible to factory reset my device or not?
Bootloader is NOT UNLOCKED, and I am stuck on bootloader screen.
"Bootlinux Failed: Not started" when trying recovery mode.
"Slot Unbootable: Load Error" when trying to start.
My device is obviously not found under adb devices as it is locked, but does show up in fastboot devices.
My computer does recognize the android device as well.
Is it possible to factory reset my device or not?
Is there any way to flash a custom ROM and get it operational?
I'd say you're out of luck, I've had the slot unbootable error/ authload error and both usually require re flashing the bootloader, radio, boot.img or a full factory image restore via flash-all to restore via an unlocked BL. I haven't seen any other methods available for the walleye with a locked bootloader I can offer either.

Hey Somin,
I haven't fully looked into that option yet, started to give up. But I can't access recovery mode or even get out of bootloader, and usb debugging is not enabled, oem is locked.
If you have any further information or ideas I would be really keen to hear.

I do appreciate your help, but as I just mentioned, I am stuck in bootloader screen and get errors when trying to access recovery, download, start or any other option. Obviously using the hard reset only brings me to bootloader where I am stuck.

Hi! No Shut down your phone and try "the game" with power button and vol+ btn... I didn't find any tutorial and it is slightly lottery, but you could get directly to recovery mode if you will press this btns in correct way:
- try to hold them for long time
- try to hold power btn and quick pushing vol+
If you will get to "no command" screen, press again pwr+vol up and you should be in recovery mode. Good luck

Interesting, I get the same error message as I do when I try to enter Download Mode. So this is different than the power and volume down, and different than just restarting it.
So far I just keep getting back to bootloader screen saying operation denied. But might keep trying it here and there haha.
Thanks for your help.
I had the same problem. I was able to solve it by selecting the download mode in the bootloader. There was an error message. Then I fastboot flashing unlock on the console. Then the bootloader is unlocked. No idea why this worked.
Maybe this will help someone who encountered the same problem.
