[HTC ChaCha] smgserver:
I HATE (ERROR [190] ROM IS NOT UPDATED)

After a countless number of try and error searching for a solution to unlock my HTC ChaCha after the latest OTA I found the solution and it was pretty simple and straight forward :)

All Thanks & Credit to:

adlx.xda (I start looking from his topic [Unlock ] Official Unlock via HTCdev! )

theq86 (Unlocking process from his topic [TUTORIAL][S-ON] Unlock Bootloader using HTCDEV.com)

HTCDev (although they lack of support is the main reason for the problem they have a nice unlocking tutorials :D)

Follow this steps (Windows Only):

download your PH06XXXXX_Chacha_hboot_1.10.0000.exe from htcdev.com

run PH06XXXXX_Chacha_hboot_1.10.0000.exe

Press CTRL+ALT+DELETE (to open Task Manager)

Select Processes Tab then go to ARUWizerd.exe

Right-Click then Select (Open File Location)

Copy everything into somewhere else lets Say "D:\Unlock"

I'm not sure but the following files is what I used "YOU CAN KEEP ALL"

adb.exe

AdbWinApi.dll

AdbWinUsbApi.dll

fastboot.exe

rom.zip - this is the most important file :laugh:

Copy rom.zip to your the SDCard and rename it into PH06img.zip

Disable the fastboot (settings>power>fastboot then uncheck) then power off the phone(you can just unplug the battery but it's NOT recommended)

Keep Pressing down (Volume Down + Power Button) you will see white screen with few color lines just wait

the device will start checking the SDCard and will ask you to press the Volume Key to install the PH06img.zip

If it's said installed successful we good to go other than that then sorry it didn't work for your mobile

reboot again to the fastboot and plug the USB

open the "Command Prompt" or (Start Menu > Run > cmd.exe)

go to the work directory "D:\Unlock"

D:

cd unlock

fastboot oem get_identifier_token

copy the output (text to be copied similar to the highlighted one in red below)
