Strange think with bootloader unlock - One (M7) Q&A, Help & Troubleshooting

3 moths ago I have bought this device from the person, which said to me that the device is a Developer edition. The device had pure lolipop on it.
The device could be unlocked just using fastboot oem unlock. I have unlocked the bootloader, flashed couple of roms but I needed to get back to stock because I needed to send my phone to the waranty because of the camera isssue. So I have relocked bootloader and restored backup and send my phone for repair.
In the servis they have succesfully repaired my phone and send it back, but with HTC Sence kitkat rom on it. I have asked them why and they said that they had this phone in database as normal edition. I have tried again to unlock the bootloader using fastboot oem unlock but it was inpossible. I needed to get the token from the htc webside to succesfully unlock my device which I found really strange.
How it is possible that one time, device can be unlocked using fastboo oem unlock and second time not?
PS: It should be in QA thread, sorry ...

Only GPE variants of the M7 can be unlocked using "fastboot oem unlock" all other variants must use HTCDev.com. The stock developer edition have its bootloader factory unlocked.
Developer Edition M7 are also running Sense, the only variants not running sense is GPE.

Phone was probably a converted GPE edition. Then they have restored the original version on the phone, including the corresponding bootloader which can not be unlocked using "fastboot oem unlock"

[Q] What happens if I unlock a dev edition?

Just as title says. I'm new to these unlock stuff and accidentally tried unlocking (did every steps to the end) a dev edition of HTC ONE (which I figured out later that it came bootloader unlocked).
So, is it any harm to the phone? Do I need to reverse the locking status? (e.g fastboot oem lock?)
Thanks in advance
No should be fine

[Q] How to unlock a relocked bootloader?

So I have a developer edition HTC One, and it comes bootloader unlocked. So I tried a few ROMs and decided to go back to stock and I needed to lock the bootloader to run RUU. So I did fastboot OEM lock, and now the bootloader says relocked. So I want to do the Google Edition Conversion and I have no idea on how to unlock a relocked bootloader. Reading that back to my self it sounds ridiculous but any help would be amazing. Thank you.
You would need to unlock it like if it was locked from HTC. Go to HTC dev's website and follow the process to get an unlock token. It gives step by step instructions.

[Q] HTC one Google Edition - Bootloader Unlock

Dear all,
I have an issue that has dazzled me for a few days ..
I have a 4.2.2 Kitkat HTC one google play edition and would like to install a custom rom.
The first step should be to unlock its bootloader
I've gone through the online tutorial and did exactly what is needed .
1) Loaded into fastboot mode
2) fastboot oem get_identifier_token
3) I received the token and pasted it in HTCdev and got back the unlock_code.bin file
4) entered fastboot flash unlock token Unlock_code.bin in the terminal ..
This is supposed to trigger my phone to display the "Unlock Bootloader?" screen, as attached ... and this is not happening
I have all drivers installed properly and my phone has responded to the fastboot oem get_identifier_token command
but there is no screen displayed .. only the fastboot mode .
What should I do?
Appreciate any help you can give

I though for the GPE you only needed to fastboot OEM unlock.

Unlocking the bootloader on GPe 4.2.2 is not possible any more. Also if you have an unlocked bootloader from before 4.4.2 OTA, don't ever relock cause you will not be able to unlock again. Google removed the partition that had the unlock splash screen. I have tried. The only way to unlock it is to find a signed 4.3 GPe RRU and downgrade. So if you are not rooted and S-on a signed RRU is our only hope! There is way to unlock if you are rooted or S-off.

Unfortunately you can NOT run a signed RUU to downgrade. This is going to have to come as a patch/update from google now

This is really pain in ass. I am contacting both HTC and Google support for this. You can read it here

Thanks for your replies ..
I have to say that I now hate my phone .. I moved from IOS because I wanted the freedom of customizing my phone and installing ROMs and now I'm stuck
I thought a pure Google edition phone will be the least restrictive version of Android. .
I should have chosen the Sense 5.5 one ..

HTC One M8 Cannot Unlock Bootloader

First and foremost, My One M8 is S-On but so far I haven't had any problems with it. Had TWRP and Xposed installed before and did a Full RUU wipe and OTA'd to Marshmallow. As far as I am aware of there isn't a current root method yet? Did anyone successfully unlocked their bootloader? It seemed that Sprint or HTC removed "Enable OEM Unlock" in the developer section. When I tried to unlock the bootloader, my phone only boots to FASTBOOT USB. No more Unlock bootloader page with the Yes or No. Do I have to request a new Unlock_code.bin from HTC?

Re-lock bootloader

Hi,
Some time ago I unlocked the bootloader and rooted my device. Didn't know it was possible to root without unlocking the bootloader (yes, i'm quite new to rooting etc.). Now my phone has a defective headphone-jack and I need to send it on repair. Anyone know how to re-lock the bootloader so I still have the warranty?
Currently running sLIM 4.8 by Wajk.
Use flashtool
Thanks, but it says on Sony's website that the phone stays unlocked even after using flash tool?
Code:
fastboot oem lock
Never done it in Sony phone but most of HTC, Nexus and few other brands I'm locking just with this command.
