[Unlock-Guide] Workaround for latest OTA Issue (ERROR [190] ROM IS NOT UPDATED)

---

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 )

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
• 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)
    

    ... INFO
    INFO< Please cut following message >
    INFO<<<< Identifier Token Start >>>>

    OKAY

  • don't close the CMD window (we will need it later)
• go back to HTCDev.com at the in of the download page click on (Process to Step 1)
• just click on (Process to Step 5)
• just click on (Process to Step 8)
• paste the coped token from the cmd to the textbox at the end of this page (My Device Identifier Token)
• you will receive an email from HTCUnlockbootloader to your account email (I received it immediately) with an attachment Unlock_code.bin
• copy Unlock_code.bin from the email to the work folder "D:\unlock"
• in the cmd write
  

  fastboot flash unlocktoken Unlock_code.bin

• Read the message at your phone
• Press Volume Up to chose Yes
• Press the Power button to Unlock your phone
• Congratulation your phone is officially unlocked
  
  Installing Recovery

Great job

Great job mate! I unlocked my girlfriends HTC Chacha. Running on stock plus rom.
maybe 3 little things for new users:

"reboot again to the fastboot and plug the USB"
has to be: reboot again, delete the file from the sd-card, power down and boot into fastboot and plug the USB.

Copy the recovery.img to the work folder "D:\unlock"
in the cmd write
Code:

fastboot flash unlocktoken Unlock_code.bin

Code has to be: fastboot flash recovery recovery.img

last step: get root
Download su-2.3.6.1-ef-signed.zip
put it on your sd-card and install it with CWM.

But anyways, you did a really great job!

Kind regards,

This worked for me. The only problem I kept running into was the pasting part on the HTC dev page. It kept saying wrong info. When I looked at the info, it was pasting what was on the htc page. So I minimised everything except the htc page, pasted and finished, got the unlock code from HTC. Just a tidbit of info in case someone else has that issue.

It worked for me too. I have ATT status goldcard-flashed to Asia WWE.

I was able to flash cingular hboot and unlock bootloader while on Asia WWE.
