How many times you get “certificate error” while trying to install some cool application on your symbian mobile phone!? It means you want to install unsigned application, and if you want successful installation you have to sign it.
- First you have to get certificate and key. You can do it by yourself at OPDA, or you can put your request here . Post your IMEI (dial *#06#) and model of your mobile phone here, and you’ll get certificate and key.
It takes time to get certificate and key, so be patient (can take up to 5 days).
(For Your Certificate and key, see below in the comments! After a while, we will delete posted IMEI)
- After you get certificate and key file, use one of these programs for signing applications.
SignSIS-GUI - sign application on your PC with cer and key. Browse certificate and key and application you want to sign!
FreeSigner - install it on your phone. Copy certificate and key file on mobile phone. Start FreeSigner, go to Options – Settings – into Sign Cert transfer certificate and into Sign Key key file. Then Add Task, file you want to sign and Go!
SiSSigner – run SiSSigner on your PC, select SIS file you want to sign, select certificate and key to sign app…for key file password just leave blank.
