Hi I have unlocked bootloader via htcdev but done nothing else. I am still on stock rom but would like to now run the new ruu. what should I do. how do i lock the bootloader again. Thanks in advance
Use adb/Fastboot tool from command prompt in windows.
Load the phone into bootloader, connect your phone through usb to your computer and run the following commands:
Fastboot devices
Fastboot oem lock
You may need to install HTC sync for the usb drivers
This will lock your bootloader.

Hi,
My phone is bricked and it won't come off the splash screen. I can't run into recovery mode, I can only run fastboot commands. Whenever I try to do something (install CWM, fastboot recovery) I get the message "Command not allowed" and I think it's because the bootloader is not unlocked.
The only tutorials I find to unlock are using abd commands, but since the phone is bricked I can only run fastboot ones.
Is there any way yo unlock it by using fastboot commands?
Thanks
Found a solution

Hi.
But a question that I think will be important... What have you done to get the bricked phone? Because if it was for a bad upgrade... there are many ways to correct it. But it is important to know how it has been.
i have registered on htcdev.com.
i followed the steps to the point where i had to execute the fastboot file to get an identifier token using a cmd command.
for some reason it say "waiting for device"
it has been like that for hours.
tried it about 3 times. I had a problem with rebooting into bootloader using VOLUME DOWN + POWER button so i ised abd and it worked
exact command i typed was "fastboot oem get_identifier_token"
PLEASE HELP ME
You don't have the right drivers for fastboot, it seems.
Find a guide and install them.
I always run ADB devices or fastboot devices first to check that I'm connected to the phone, before running any other commands.

Hi
I have unlocked the bootloader using htc-dev unlock as there is no aahk. i followed the link tau.shadowchild.nl/attn1/?p=88[/url] and i have done upto step 4. after that i tried installing cwm and it fails. after reeboting my phone its on stock firmware 2.3.5 and sense3.0. i want to flash a custom rom onto this device. can u people help me when i tried to enter into hboot mode the top of my inspire 4g screen says bootloader - relocked. What to do now. How to flash cwm into it and install custom roms.
Thanks in Advance.
Why are you following that guide? It is for preparing an Inspire 4G with the latest update for AAHK, which no longer exists.
You cannot flash CWM unless you re-unlock your bootloader; you can't flash anything when the bootloader is locked.

using the same unlock_code.bin as before:
Plug the phone with usb debugging enabled.
Open a cmd as admin and type adb reboot-bootloader.
When in fastboot usb (you should read that in the phone) navigate to where the unlock_code.bin file is in.
Type fastboot flash unlocktoken unlock_code.bin
Voilá...you are done.
If you don't have the unlock_code.bin, then get another token from phone the same way as you did before.
Hi,
I got into a frustrating situation, I installed Oneplus OTA update after that phone is stuck in bootloop, only thing I can access is fastboot, after reading many articles, I found that unlocking bootloader can fix my problem.
But unlocking bootloader has become worst nightmare in OnePlus one, when I run # sudo fastboot oem unlock, it will reboot phone and goes into 1+ logo, then I reboot the phone again boot into bootloader and situation is still the same bootloader is still locked.
I also tried OnePlus toolkit, onplus toolbox and oneplus tool for linux, nothing is unlocking the bootloader.
Phone is not enabled for adb (debugging mode).
adb shows "offline" mode while phone in bootloop logo.
is there any way I can atleast force the phone to unlock boot, any help is appreciated?
I am a linux user, but I aslo tried in windows, samething.
Thanks
I think you need to sit down and re-read the guide on how to unlock your bootloader because you're not having a good understanding on what you're supposed to do.
http://forum.xda-developers.com/showthread.php?t=2788632 Read that thread and adjust accordingly to Linux unless you do it on a Windows-based machine.

Hi,
Thanks for reply, I have followed the complete guide to unlock bootloader, I updated the android sdk to the latest with android drivers.
Find the attachment how I have done that, but still the bootloader is locked.
In device status it shows that device temperted: true, is there any way I can change that to false using fastboot command?,
maybe that is the thing preventing me to unlock the bootloader.
Your help is appreciated.
Thanks
Dani
I only used 15 second adb installer on my PC for adb drivers. That way I don't copy paste files into SDK folder.
Anyways fastboot OEM device-info gives back tamper true and what is the other flag?
Make sure u don't put in typo like your op "ulock" lol fastboot OEM unlock should bring up wipe options on your phone :s

Hi ek,
screen shots are attached with the reply to zephiK's message (all flags can been seen), however, fastboot oem unlock doesnt bring me wipe option (though I am ok to wipe).

After the fastboot OEM unlock command look at the phone, that is where the wipe stuff appears. Or it should.

Unlock bootloader if not done yet.
where i unlock bootloader ? In developer settings ? (i have unlocked)
Enabling OEM Unlock in Developer options doesn't unlock the bootlader, it simply prepares the bootloader to get unlocked via fastboot command.

Only I have a small problem I don't unlock my bootloader via fastboot when it doesn't work :/ It immediately jumps to my system when I boot fastboot, even with a command like ,,adb reboot fastboot"

I don't know if you are still interested in accessing Fastboot but you can access it using a specific firmware version.
Still, let me tell you that unlocking the bootloader is virtually impossible. Since the well-known generic method doesn't work for the SoC SC9863A, you need to have a special Fastboot's program version and a dedicated private key that only they provide.... and I emphasize the word "dedicated" since apparently ZTE did not use a generic key to sign their ROMS. At least on this device.
Unless they decide to release the key or give support to unlocking the bootloader, all we can do is wait for them to change their minds. Because they don't want to provide it. I know because I tried to order it several times.
