No fastboot option

Can't find anything on these forums or with google on this issue:
Unlocked HTC 10 purchased directly from HTC last week, received yesterday, running with AT&T SIM. Trying to unlock bootloader with HTCDEV but when I boot to bootloader or download mode there is no option for fastboot! Volume down + power brings me to download mode, my options are system info, show barcode, reboot to bootloader, reboot to download mode, reboot, power down. Tried reboot to bootloader. Phone reboots, says ***LOCKED***, ***S-ON*** and I have the options for reboot, reboot to bootloader, boot to download mode, boot recovery mode. I've ensured USB debug is ticked and OEM unlocked is allowed. I'm afraid I'm missing something obvious but I've used fastboot a fair bit on my m8 so I know what I'm looking for. I put a call in to HTC and their "special Bootloader Unlock team" is supposed to email me in the next 3 to 5 business days.
Tried a hard reset, didn't help.
All I could find on Google is some folks discussing an issue in earlier models of HTC phones - in those cases something about unticking fastboot in the "battery" menu of settings seemed to help but I can find no such options in the marshmallow variant on my phone. The HTCDEV site offers:
"If you have difficulty, power up normally, go to Settings->Battery and deselect Fast boot. Power down and try again." Must be referring to something from an older device because Settings --> Battery does not exist and Settings --> Power does not have a "Fast boot" option I can find to deselect.
Anyone have any thoughts?
Thanks...

It's has been renamed to "download mode" since M9 I think.

theres no fastboot option, it was changed to download mode on recent htc devices
once you're in phones in download mode & you have fastboot open on your pc
type "fastboot oem get_identifier_token"
the rest should be pretty easy

Htcdev explains all that on the first page of instructions as well.

Oops, got it...

Thanks guys, sure enough I was connected all along. I should have been able to figure that one out!
I'm not so sure Htcdev "explains all that" though. On the contrary, their instructions were the source of confusion! The first page says to "Use the Volume buttons to select up or down. Highlight Fastboot and press the Power button." Their note of clarification does not help, launching into a discussion of enabling OEM unlock. They ought to update that. Why on Earth would it be clear to me that connecting in 'download mode' instead of 'bootloader mode' voids their specific instruction to "select fastboot and press the power button"?
Anyhoo, all set with a freshly unlocked bootloader, thanks again.

Hello there...
Can you Please tell where the download option is available in HTC devices?

Some custom ROM's allow you to reboot to download mode via the power menu. If you're stock, power off the phone. Once it's off, hold volume down+power. Once the black HTC screen appears release both buttons. The phone will boot into download mode.

Hi Folks
I just got the Media Pad M2 8.0 and I want to check if the bootloader is locked or not

Yes, there should be. You need to enter fastboot mode on the phone - i.e you need to get into the bootloader screen. The bootloader screen (usually called fastboot mode) will tell you if the bootloader and FRP are locked or unlocked - If it is locked, you should see "PHONE Locked" and "FRP Lock" in green, otherwise it should say "PHONE Unlocked" and "FRP Unlock" in red if the phone has been properly unlocked.
You can enter fastboot mode by either using ADB ("adb reboot bootloader", first make sure to enable developer options first as detailed in the Rooting guide, and then enabled USB debugging), or by first shutting down the phone and then powering it up while holding down the VOLDN (Volume Down) key. Of the two methods, I'd recommend the ADB method because the hardware keys method is usually hit-or-miss for me - sometimes it takes me to the bootloader, sometimes it boots normally into the ROM.
If you're on Windows and need the ADB and fastboot binaries, you can install the "15-second ADB installer" found in this thread.

Thanks, that worked, took me a while to figure everything out...
and it appears that my device is unlocked...

Hold vol dwn and power till it shuts off then quickly plugin the usb cable from your pc and hold vol up while you plug it in and wait till download mode shows up.

SM-G960F/DS help needed with preparing for Root

Couple questions
I just picked up a SM-G960F/DS for experimenting with and am wondering about rooting it. I haven't put a SIM in it yet. Can it be used without a SIM card? I don't plan on using it as a phone just connecting it to Wi-Fi and experimenting with it. I am not sure what firmware to put on it. It came with BUILD R16NW.G960FXXU1BRF8. I live in Canada and I am not sure which firmware to download for it.
As far as rooting goes does it need a SIM in it to do any of this? Can i just add my Google account to get my Apps on it after rooting?
I have not rooted anything since my S6 and searched a bit and think this is the steps to root the S9.
I think that I should first be on latest Firmware before starting this?
Steps as I found info on process to get Root
got Odin3_v3.14.1.zip on PC and USB drivers - my SM-G960W connects okay
1 enable OEM unlock on phone
Downloaded twrp-3.3.1-1-starlte.img for S9 to PC
Use Bixby Key+Volume Down+Power to enter Download Mode and connect the device to PC USB
2 Open Odin and un-tick auto reboot in "options" tab, make sure that device is detected, Put twrp-3.3.1-1-starlte.img file into AP tab, Click Start
3 When Odin shows "PASS", disconnect the usb cable and press simultaneously the "Bixby key" + "Vol. Down" + "Power" buttons until the download mode disappears
At the precise moment the screen becomes black, immediately release the "Vol.Down" button and press the "Bixby key" + "Vol. UP" + "Power" buttons during 10 to 15sec to forcefully enter TWRP recovery
4 in TWRP swipe "Allow modifications"
5 Go into Wipe menu and select "Format data"
6 Reboot into TWRP recovery again, swipe to "Allow modification" connect phone to PC again Put RMM-State_Bypass.zip and no-verity-opt-encrypt-6.1.zip zips into external sdcard (or does this get done all in step 5?)
7 Flash RMM-State_Bypass.zip
8 Flash no-verity-opt-encrypt-6.1 zip
9 Reboot the phone into system Setup Google account.
now it gets confusing as to what to do for root...

So any help?
I imagine that the first thing I need to figure out is what firmware to download for it.

Samsung Note 10+ N975F; kylo ren picture right after start, boot loop

Has done, if no longer needed can be deleted
solved
Download Mode:
1 Step: Device switched off
2 Step: Keep volume up and down pressed
3 Step: Connect the keys to a PC via USB-C while keeping them pressed
Hi Guys,
I bought a Note+ (N975f, DBT) used. Since it has a crack on the front and was therefore cheap, I wanted to root it.
because as a newbie I am not allowed to insert external links, here only hints:
Following the instructions of topjohnwu with Magisk
However, it did not work. It is always at this point, red marked:
"Unlocking Bootloader
Unlocking BL on modern Samsung devices have some caveats, so I figure this would be helpful.
Allow bootloader unlocking in Developer options → OEM unlocking
Reboot to download mode: reboot and press the download mode key combo for your device.
Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
failed.
In download mode when pressing Vol + key the following appears in red
"Reboot Recovery Cause: BL: Recovery Mode Set by key"
I have tried several times and I got this version from
samfw firmware/SM-N975F/DBT/N975FXXU6DTJ4
is used.
I assumed that it is because of the firmware then I used this version
SM-N975F_10_20201103172903_jy9pngyoln_fac
from Frija is used.
For flashing I used Odin3-v3.14.4.
After the last try with the version from Frija (Odin didn't show an error) a screen with a photo of the mask of Kylo Ren appears after Samsung. After 1 minute it starts again.
it is this picture
soyacincau 2019/11/191120-samsung-note-10-wallpaper-preview jpg
In Odin it is detected, but flashing again is not possible it stops at "SetupConnection".
I can only turn off the phone when it is connected to the PC and hold down Bixy/Power + Vol up.
Can I still save it, if so how?
Thanks in advance
