Rooting HTC Desire HD A9191 2.3.5 – Vodafone with AAHK Saturday, 21 April 2012

First of all many thanks to AAHK (Advanced Ace Hack KIT) team for making this so easy and possible, awesome release. Here i put on paper my root experience step by step.

  • OS: Windows 7 x64
  • Phone: HTC Desire HD A9191 (Android v2.3.5  |  HTC Sense v3.0  |  Software number 3.12.405.1 )
  • Application: Advanced Ace Hack Kit v.13012012
  • Custom ROM:  Android Revolution HD v6.3.2
  • Drivers: HTC USB Driver v3.0.0.007



  • download [aahk-13012012.zip] and unzip

  • read carefull the [effen-manual.html]
  • make sure no antivirus software is enabled
  • make sure you uninstalled all software related to your phone (HTC Sync and drivers) or other phones, PDA and tablets you may have
  • into your phone go to Settings > Application > Development > [tick] USB debugging
  • install HTC USB Drivers for Android from \Advanced Ace Hack Kit\tools\windrivers\HTCDriver3.0.0.007.exe
  • download a custom ROM. If you want something that looks like stock ROM, with Sense 3.0, etc … my suggestion is Android Revolution HD (many thanks to Android Revolution HD team for great work)

Running the process:

  • execute with Administrator privileges: hack-ace.cmd (for Windows 7)
  • enter the generated PASS KEY by pressing CAJUN.txt in [effen-manual.html] or you can find it in: \Advanced Ace Hack Kit\tools\txt\CAJUN.txt and press ENTER to start the process
  • the AAHK will check the version of your installed Android to see if is compatible, if is not compatible will automaticaly suggest to downgrade (see AAHK DOS Window Step 1 – Page 1) … type Y if you want to do it. RRU download will start (for me 247MB in 82sec at 4MB/s). When download is complete the process will copy required files to your phone SD card and the phone reboots in HBOOT, will continue with file integrity check (see AAHK DOS Window Step 1 – Page 2)
  • if everything is fine will prompt you to press [Volume Up] to start the downgrade process (see DHD-HBOOT Step 6.01)
  • after successful downgrade press [Power] to reboot, the phone will start normally as first time with wizard to configure the basics (see DHD-HBOOT Step 6.08-10)
  • now, to get ROOT just run again [hack-ace.cmd]


Install custom ROM:

  • disable [Fast boot] … Settings > Power > [untick] Fast boot
  • power-off and start your phone in recovery mode [Volume down + power] … keep the keys pressed till you see the HBOOT screen
  • from main menu chose Recovery to access AAHK ClockworkMod Recovery
  • here you choose ether [apply update from sdcard > Yes – Install /sdcard/update.zip] or [install zip from sdcard > use /sdcard/update.zip]. Wait till complete message appears [New ROM flashed successully! Reboot your device …] and reboot. First time boot after flashing will be longer (about 3min), just be pacient. (see Flash custom ROM)


HTC Desire HD button functions:

  • volume [+ /-] is for menu up / down navigation
  • power/screen-lock is for back into the upper menu

    I have done all of the above but still my HTC Desire HD won’t accept sim from other carriers…it says ‘NO SERVICE’

  2. Q says:

    ROOT does not necessarily unlock the phone, this article is only about ROOT-ing. To unlock the phone you need either to ROOT with Gold Card which is much complicated or try this application, here: http://forum.xda-developers.com/showthread.php?t=943726. But i suggest to ask first if is working with HTC Desire HD, they say is working with HTC Desire, should work with HD too but you better ask first.

    I did all the steps and after the boot screen – slide 10, resetou my unit and was left with only a white screen and green HTC symbol and now I can not access it via usb and it does not reboot, does anyone have any suggestions do? I appreciate your attention!

  4. Q says:

    Power off the phone and try to access HBOOT. Hold Vol- and power on the phone. Then factory reset.

  5. Marcelo Báfica says:

    I’ve done this procedure, I can only access the hboot when access the recovery is there with the red triangle with exclamation. When I try to factory reset it tries to recover but then turns off.

  6. Marcelo Báfica says:

    Q Thank you for your attention … Follow the steps in this video (http://www.youtube.com/watch?v=MkiTmQ55cQQ) and made ​​it to the time 3 minutes and 6 seconds of the video, only to request the installation of update.zip accuses E: signature verification failed, installation aborted.

  7. Q says:

    Since is not a stock ROM you need to turn off the < toggle signature verification > option in the Settings menu. Here is: http://jaxov.com/2010/10/fix-android-no-signature-verification-failed-error/

  8. Marcelo Báfica says:

    apparently I need is a Stock ROM, because during the many attempts ended up doing a full wipe, factory reset. Do you know any tutorial for applying RUU?
