This article is for AdGuard Pro for iOS users exclusively. If you are one, there’s a chance you would like to revert to version 1.2.1. How and why — find out here.

A bit of background story first. As you may have heard, about a month ago Apple had announced unexpected news about their policy regarding system-wide ad blockers, which have had major consequences for AdGuard Pro. We even wrote an article about the whole situation and why we were forced to cut some of the functionality.

One of the possible solutions we suggested was to not to update AdGuard to the new version. But what if you already did? There is a way to revert back to v1.2.1. Albeit not the easiest one, there’s nothing too hard either if you have an instruction like the one below.

  1. Download the latest version of the Charles Proxy application for your operating system here:

  2. Install the application, then run it.

  3. Follow these instructions depending on your OS.

For Windows:

  • In Charles settings go to Help — SSL Proxying — Install Charles Root Certificate. Click Install Certificate, then choose Local machine store location, click Next:

  • After that, mark ‘Place all certificates in the following store’ and browse for Trusted Root Certification Authorities:

  • click OK, then Next and finally, Finish button.

For Mac:

  • In Charles top menu go to Help — SSL Proxying — Install Charles Root Certificate. In Keychain Access double-click on Charles Proxy CA and choose ‘Always Trust’ when using this certificate:

  1. Make sure that ‘Recording’ notice is present in the bottom-right corner. If it’s not, go to Proxy — Start Recording.

  2. Open iTunes and search the App Store for ‘AdGuard Pro’, then download the latest version of it.

  3. A string will appear in Charles, right click on it and press Enable SSL Proxying.

  4. In iTunes go to Library — Apps and delete AdGuard Pro.

  5. Search the App Store for ‘AdGuard Pro’, download it and then delete it one more time.

  6. In Charles expand the new string, find the buy product entry, right click on it and select Breakpoints.

  7. Open App Store, search for ‘Adguard Pro’ and download it once again.

  8. A ew window will open in Charles, open Edit Request tab at the top and then the XML Text tab at the bottom there.

  9. Replace the numbers you have in 5th string there with 821782275. Press the Execute button two times in a row:

>NB: Don’t forget to right-click on the string and disable SSL Proxying before you exit the Charles application.

  1. AdGuard Pro version 1.2.1 will be downloaded from App Store on your PC. You can connect iPhone to iTunes, click on the phone icon, then select Install for the AdGuard Pro app in Apps section and press Apply.

Provided you did everything according to the instruction, AdGuard 1.2.1 should be now successfully installed on your iPhone. Congratulations!

Do not forget to disable automatic app updates in iPhone settings, or the latest version will be installed again undoing all of your work:

  • Open the Settings app.
  • Swipe up until you find iTunes & App Store.
  • Under Automatic Downloads, turn off the toggle next to Updates.

We want to express our special gratitude to UmarFarq for the excellent idea and the instruction he shared with us.
