One M8 (Three UK) network unlocked - can't root?

I want to use the Root call blocker app which requires root access.
HTCdev instructions for root emphasise that 'OEM unlock' should be ticked in developer options before proceeding further. This option is not shown in my developer options screen & when I look at the bootloader screen the top item shows **LOCKED**
I guess this is why OEM unlock isn't shown.
I'm a complete novice & my only reason to root (so far....) is to use that particular call blocker. I have called HTC & they don't seem to know what i'm talking about...they think i'm asking how to get into developer options screen! Any help will be appreciated & explanations in simple terms also

Ah.. you don't reply in other thread but you open a new one.. and I asked moderator to move this to Q&A section.
Why don't you use any call blocker apps that don't require root access ? There are many of them on Play Store.
Anyway .. to root your M8, you need :
1. unlock the bootloader thru http://www.htcdev.com/
2. install TWRP recovery
3. install SuperSU.zip
There is no such thing "OEM unlock" on M8

Hi, Thanks for reply & sorry for posting in wrong section earlier.
The reason I want to use 'root call blocker' is because unlike other such apps it doesn't use the ring & hang up or divert to voicemail method. It kills the call completely & as such avoids the single ring scam which has just started to affect some phones here....mostly Vodaphone users. As yet no one is sure how the scam works but the victims are left with huge phone bills & have never called the number itemised on the bill. So......that's why I want to use that app.
Regarding Htcdev.....I have registered with them, having researched them as probably being the safest for someone with no experience & it is the reason for this post as I quote below step 2 of their instructions
''Step 2
Use the Volume buttons to select up or down. Highlight Fastboot and press the Power button.
NOTE: All new HTC devices shipped since One M9 support download mode instead of bootloader mode for this step. And for select HTC devices with Android Lollipop and all devices that receive Marshmallow, you will need to first manually enable OEM unlocking in Developer options in order to allow the bootloader to be unlocked and proceed with the next steps.''
The reason I can't proceed is because my device does not show the option for OEM unlocking....yes I do know how to get to developer options.
I have tried all the ''one click root'' methods & they haven't worked........so......any help?

There is no OEM UNLOCKING on HTC M8, only certain/newer devices have that.
In step 2, they explain how to get to fastboot screen. If your current screen show hboot (highlighted in blue) -- press power once to get to fastboot screen
As long as your screen now is showing fastboot usb (highlighted in red) when connected to PC .. you can proceed to step 5 to run command
fastboot oem get_identifier_token

No option to enable OEM unlocking. HELP!

I have a htc one m8 from Sprint. It is currently running 6.0 or 6.2 and I want to unlock it. I need to unlock the bootloader but there is no option in developer. How can I get the bootloader unlocked if there is no option to waffle OEM unlocking?

Living in the UK, I know practically nothing about Sprint devices, however the bootloader OEM unlock option (in developer settings) you refer to, as far as I'm aware is only found on recent-ish Nexus devices.
I have it on my Nexus 9 tablet for example, and apparently it's also on the Nexus 6P phone.
I've never heard of it on non-Nexus devices.
***
The way I unlocked my M8 bootloader, was by registering an account with HTCdev.com and I requested a bootloader unlock token, which is a tiny file emailed back to you as an attachment (full instructions are given at HTCdev.com).
This file/token is then incorporated into the fastboot OEM unlock command.
Sorry if all this is a little vague, but this is something I did back in July of last year, so my recollection of the precise details are a little hazy.
And as I've indicated, I know nothing about Sprint devices so this procedure may not be available to you.

I'm in the UK and did the same on an M8 6.0
The HTC developer site can be a bit off putting as the instructions are as follows:
"To access the OEM unlocking setting on your device, open the Developer options in the system Settings. On Android 4.2 and higher, the Developer options screen is hidden by default. To make it visible, go to Settings > About > Software information > More and tap Build number seven times. Return to the Settings screen to find Developer options and check OEM unlocking."
That last bit is not there. Just ignore OEM unlocking. I found that getting the token and using it was not explained that well either. The phone has to be at the bootloader. Press the power button with the fastboot option selected and then the usb cable attached. Then just leave it and follow the instruction on the HTCDev site
To get the token key in windows 10 it's probably easier to use the powershell (click start button and type in Powershell to find it. Right click with mouse and select 'Run as administrator') rather than a command prompt, as you can 'mark' the text you want only - and not all the line headers. After selecting press ctrl-c to copy it and paste into the box on the HTC web page.

Hi Johny,
I'm just doing the same with an HTC ON M8 from UK too, with Android 6.
I have no idea what to do, and yes you are right the OEM unlock is not in the menu.
I didn't really follow what I am meant to do from your comments though? Can you help?
I have downloaded the HTC dev thing and am downloading the SDK devools and the fastboot .exe but dont really know what I am meant to do with them1

This phone never had the option (nor the requirement to do so) in Settings for OEM unlocking. It was introduced by Google in later Android builds.
In short, you won't see it on the Settings menu (as you already mentioned) and you therefore do NOT need to activate it. Basically, you don't need to do anything in Settings to unlock the bootloader.
Just go through the bootloader unlocking process as outlined in HTCDev.com skipping the part about OEM unlocking (or use guides on XDA for the M8) and it will unlock.

Thanks I finally got the token to work through a few things.
I used this guys video and Windows Powershell needed to use a .\ BEFORE the fastboot commands to make things work...

[SOLVED]Need Help Regarding Bootloader Unlocking Of Mi Max Prime(128gb)

Hi Everybody,
I need help regarding Bootloader Unlocking of Xiaomi Mi Max Prime(128gb).
I`ve all the prerequisits :
1. Unlocking Permission
2. ADB and Fastboot Drivers Installed
3. Mi Acoount activated
4. Usb Debuging, OEM Unlocking, Usb Debugging(security Settings) Options - ON.
5. Mi Cloud - Find Device - ON
6. Device Located (Both in Device and PC).
7. MiFlash Unlock Tool - Account verified for Permission.
But can`t Add Device and Account through Mi Unlock Status option in Device - It always shows "86012 with some chainis languages".
I`ve tried FlyVPN too to add the device and account, but can`t add.
It always shows "Couldn`t verify device - Current account is different form the account info on the device" - when I use any Old version of MiFlash Unlock Tools (i.e MiFlashUnlock_1.1.1111.1_en, MiFlashUnlock_1.1.0317.1_en etc).
And it always shows "Current account is not bound to this device"
In the "Settings -> Developer options -> Mi unlock status" binding account and equipment
" - when I use the latest version of MiFlash Unlock Tools (i.e miflash_unlock-en-2.2.406.5 ).
I really don`t understand, what I`m missing ?
It`s being 6 days I`ve got the permission, can`t even yet unlock the bootloader.
Would anyone help me to unlock the device?
Any suggesstions/advice will be highly appreciable.

Resolution - Developer Options > OEM Unlock toggle disabled on XT1955-5

Greetings,
I just wanted to share my solution to resolution of a brand-new Moto G7 Power XT1955-5 having the developer option "OEM Unlock" disabled. I see issues for a separate model here:
https://forum.xda-developers.com/g7-power/help/oem-unlock-greyed-t4061763
I do not know if my solution will work for other models. My XT1955-5 was manufactured in 2020 06 and purchased in US.
My intent here was to get the bootloader unlocked for installation of custom ROMS as quickly as possible.
Start Phone
Skip all setup options.
Enable Developer Mode
Enable USB Debug
In about phone > time/ date settings, disable all toggles
Set phone to a period of 8 days ago - arbitrary number
Reset Phone
Reset Date to correct date (leave toggles as-is)
Connect to a wireless network with access to Internet (I was using a WiFi, and did not try data)
Read first before attempt - Done quickly -> Phone begins downloading security patch (or it begins with next step - not sure) - Done quickly -> Attempt to set up an account (Google) whilst phone is downloading security patch - account setup waits for security patch update - Proceed to developer options - OEM Unlock toggle is available - Toggle during download.
I strongly suspect that there is some trigger associated with either downloading a security update, or simply attempting to enable an account on the phone (which requires you to be connected to data), but I do not know which. It is likely that there is not specific time sensitivity involved, but I am including my exact actions that resulted in success.
I hope it helps. Happy development!

Yes. The bootloader is now unlocked. I did have to obtain an unlock code from Motorola. The primary issue here was the inability to toggle "OEM Unlock".
I was using Motorola's guides that are linked from this website:

Unlock greyed oem option help

I have a metropcs Oneplus nord n100 I'm trying to access the the bootloader but oem option in developer mode is greyed out. Also i don't own a pc is there any way i can unlock.bootloader without a pc?

There are a few devices on which the bootloader can be unlocked without the need of a PC and fastboot command sets. For example, many Samsung devices can be bootloader unlocked by going to device Settings>About Phone and tapping Build Number 7 times until Developer Options is enabled. In Developer Options, enabling the OEM Unlock option will unlock the bootloader, thus disabling the layer of protection which restricts flashing of certain device partitions. Other than Samsung, there are some device OEMs and models which also allow bootloader unlocking in this manner. However, on most devices, in addition to enabling OEM Unlock, fastboot mode must be initiated, device and PC synced with a cable, and a command line or command set must be executed.
If your device oem unlock is greyed out, you can try unlocking it using fastboot and recovery mode with the help of a pc.

Thanks i will do further research and once again thank you for taking the time to reply

Carrier-locked devices generally do not have unlockable bootloaders, or at the very least until 6 months has passed for a SIM unlock in the case with Metro going by how T-Mobile handled bootloader unlocking with the OnePlus 6T. However, that's unconfirmed and I could not find any information on either carrier-locked models for the N100 regarding this matter. So for now, it's a dead end.

yes I'm having the same issue here with the be2015 metropcs variant. They're saying 180 days (6months) till able to unlock this phone. I've been searching for some sort of way around it but no lock as of yet. Please everyone keep us all updated just in case.
when i do
Code:
fastboot oem unlock
I get FAILED (remote: 'Flashing Unlock is not allowed.
I've been trying to follow this guide here with Shizuku but I'm also running into issues. any help here please? Thanks yall

Yeah, that tuturial in the other post that the mod locked, he also deleted the commands. I'm guessing there's an issue that xda doesn't want to be involved in, kinda like writing new imei's. So I guess we're kinda screwed.

I bought this phone cheap, €117 at a discount. And Its EU version, where I can unlock the oem bootloader on this phone.

You can enable OEM unlock in Debug menu with debloat until from girhub, but you cannot unlock bootloader in metro phones.
Even if you have got unlock token, OnePlus says that's imei failed.

So is there any way to unlock this phone from carrier?

if it's metro, it has the unlock app on it; still have to be paid up and 180 days in on your account, though

Just for the record everyone:
Bugjaeger Premium - Apps on Google Play
Debugging and maintenance tool for Android devices
play.google.com
Bugjaeger Premium actually allows you to use an OTG Connection, (Android-->Android), that enables A Real connection via ADB/Fastboot.
So for all those that have no PC, but have two devices, it is possible to use one to run the ADB or Fastboot consoles and run authentic commands. I use it all the time since a desktop isn't so portable.
It takes a little thinking when it comes to the directories used, but I've easily ran Fastboot oem unlock and flashing commands before on the go

Tell you the truth, I was in the process of switching out SD Cards in the BE2015 and while I had the SIM/Tray out I saw that the developer options allowed the OEM Unlock toggle to be switched....
The option greyed itself back out once the sim was reinserted, but, I was able to toggle the switch ON before it did all that.
And even greyed out the option remains switched ON now.
For the record.
