Freely install unsigned applications on any S60 phone

You can now freely install unsigned applications without the need for self signing, in this post I will explain how to achieve this.

First you’ll need the following:

  • A permission hacked S60 phone, follow my previous guide, hack S60 file permissions
  • If you have a Symbian 9.2(feature pack 1) device, download installserver92 file.
  • If you have a Symbian 9.1(pre feature pack 1) device, download installserver91 file.
  • File browser eg. Y-browser, X-plore.

The list at the bottom of the post will help you decide which file you need to download.

Extract installserver.exe from the appropriate zip you have downloaded.
Copy it from your PC to your memory card, I put it into Memory Card/Apps
On your phone load up Y-browser and copy it from E:\Apps (If you are using the same location as me)

Remember you must have a permissions hacked phone otherwise you will not be able to see C:\SYS

That’s it, You can no install any Unsigned application without the need to selfsign each one, just install like normal and you will no longer receive certificate errors.
