I can not unlock the bootloader. - HTC One SV

Hello.
I have a rather unusual problem with HTC. I'm trying to unlock the bootloader and unfortunately does not change. I tried to unlock the bootloader using htcdev.com several time. It did not help. Is anyone able to help me ??
It all started when ... the my friend wrote sms and the phone rebooted and came hboot. By launching the phone is switched on immediately hboot. And nothing more can be done.
Please help.
Regards, Martin

[Q] Is my HTC desire S gone or can i fix it?

So i updated my HTC Desire S yesterday and after the update i cant get it to run beyond the htc logo screen.
It have became locked. I think the problem is the new HBOOT 2.00.0002 atleast it was the thing that started all the problems.
So i have gone on looking for fixes for this problem, tried most things. But i have a really annoying problem. I read that i have to unlock the bootloader before i can do anything to fix it. So i go on to HTCdev and go through the process of unlocking my phone. I download all i need, Get my token and what not, use the unlock token. I get to the screen that tells me to press yes to unlock it or no to just return.
Now i have a real problem here, I cant for the life of me press yes. The phone just refuses to accept it.
Is there any way to fix this? have a missed something in the process? or am i just out of luck and shall throw the phone on the ground?

[Q] Unlock a Relocked Bootloader?

So my cousin got a one x,
we followed the 36 page guide, unlocked the rogers bootloader, then flashed the AT&T firmware 1.85, and then tried unlocking the bootloader again, but not matter what happens when he confirms the unlock token, it just turns off. then he turns it back on and it sets it up, reboots to the bootloader and it still says locked...
i've tried to help him but i have no clue as far as i know...
we've gotten a new token 3 times now as well and it hasn't worked either.
does anyone else have this problem?
can he flash back to the Rogers RUU? just for stock sakes or is he stuck on AT&T 1.85 now?
thanks guys.
EDIT:
Mod's please close, figured it out, just tried using an OLD unlock code and for some reason it worked. =\
thanks anyway, sorry for the spam.

the issue is how you boot in to fastboot. If you use adb to get there sometimes the unlock wont take. i tried 10+ times with one phone. If you power off, then hold down vol- to get to fastboot, then run the unlock command it normally will work the first time. The unlock tokens are the exact same. re downloading them and using the old one probably had nothing to do with it. Glad you are unlocked now

[Q] How Do I Unlock a Tampered Bootloader

I have an AT&T 3.18 one x. The bootloader is showing as TAMPERED. I am able to successfully get superCID and get the unlock_code.bin from htcdev. I can successfully use that and the phone warns me, blah blah, and then resets everything and boots into a wiped android.
The problem is that when I reboot into the bootloader again it still says TAMPERED LOCKED. I am unable to load an custom recoveries.
Everything I read says I can unlock the BL without htcdev, but it requires root. But the way to acquire root is with an unlocked bootloader! rock-->me<--hard place.
Any advice on what to try next? I've never had this much trouble rooting/romming before, I've lost my touch apparently.
Sounds like its unlocked but the locked field I your bootloader is spoofed.. Did you buy this phone used?
If im wrong then it just means you need to keep trying thr unlock bin file over andover until it unlocks. Do a hard reset by holding thepower button until the phone shuts off between tries. Eventually it will unlock
Yes, bought it used.
I tried flashing recovery downloaded from cm install wiki and got "signature invalid".
The only way I can get into the BL is using adb or holding volume down while restarting from os.
I've done it twice, will try more.
The supercid is only the temp one meant for using htcdev. Do I need to redo that each time before applying the unlock code bin?

No you should not need to. Your bootloader is definitely still locked. Keep trying! It was probably relocked. It may take many tries before it unlocks. Ive relocked my bootloader a few times in the past for testing purposes
Success! Thanks for the encouragement!
Only took two more attempts. First tried turning off "reboot faster" option in the power settings menu before I did the restart-while-holding-volume-down. But that didn't work.
Then tried the hold-power-for-10-seconds like you suggested and it worked that time. Now I am TAMPERED UNLOCKED S-OFF and running cm10.

[Completed] Htc one mini m4 go back to stock rom

Hello everyone!
I've had my m4 for about 5/4 years now and my battery has been getting worse more and more slowly for about 2 months now. Because I want to invoke my guarantee I tried to return the phone to stock rom from Insertcoin, unroot it and lock the bootloader. I flashed the stock rom from this(http://forum.xda-developers.com/showthread.php?t=2791725) thread and everthing was working fine. After that I went into fastboot and typed the command "fastboot oem lock", because I read so on the internet. Now there seems to be no rom or recovery on my phone anymore and everytime i reboot it just straigth goes into the bootloader. None of the tools I found on google worked so I thought somebody here could help me because I'm almost getting desperate.
I will also include a link to a photo of the bootloader, maybe it's helpful (https://www.dropbox.com/s/0j7830bw6mxjjrv/IMG_20150511_190346.jpg?dl=0).
Also notice that this is one of my first posts in this forum and english isn't my mother tongue.
I would really appreciate a fast but especially useful and relative easily written response.
Thanks!
Hi, thank you for using XDA Assist. I would unlock the bootloader, fasboot oem unlock, and flash the stock firmware from the link you provided.
fastboot oem unlock error
I tried fastboot oem unlock but it just wrote "[ERR] Command error!!!". I also tried to unlock it via HTCdev again but the sites seems to be down, everytime i select my device and click on Begin Unlock Bootloader it opens this small window and says that the site is unavailable, I also tried it a few different times. Is there no other tool to unlock the bootloader or somehow get my rom started again, because I'm wondering why it's erasing or at least not giving me access to the rom that was perfectly working before anymore after locking the bootloader.
-Edit:
OK so i found out how to do it with HTCdev. I just had to create an account, log in and do exactly the same as before. I had to give it a few tries, but in the end it worked. Now my question is how I can relock my bootloader without causing the same again? I didn't find anything other than the cmd prompt fastboot oem lock so if maybe somebody could help me.

HTC U11 Stuck after firmware flash

Hello everyone,
I recently got an htc u11, my first android phone, to kind of play around with and see what I could do. I was messing around with rooting it and unlocking the bootloader etc. Then I started to play around with the firmware. Basically I got the sunshine app and flashed some firmware and now when ever it boots up it says the phone is encrypted and that if you enter the wrong password it will reset all the user data. After resetting all the user data the same screen keeps coming up.
The problem is now I can't flash the stock firmware back because the s-off from sunshine is temporary and now of course it is back on. The bootloader is relocked and it cannot boot into recovery.
Any help or advice would be appreciated
Thanks for reading
