      just use our site search engine and search for “free Signer” and download it and transfer it to your mobile and the certificate and key file too. Then sign any unsigned applications on your mobile.

    hi sony! i did whatever u instructed us above but iam facing a problem in nokia 5800xm it is showing a msg install base package first plz……..help me .email me plz.in solving this problem .thanx in advance

    • sony says:

      It is not the problem with the certificate and it is the problem with the application. It should have some another supporting file or application. So first install the supporting file. I am sure your problem will be resolved. If you haven’t downloaded the supporting application first download it and the procedure. Good luck.

  37. Akka says:

    Hi guys, thanks for the great tutorial. I’ve gotten a certificate from the ‘old system’ some time ago, worked like a charm. Now I’m trying to get another one, but the OPDA site shows no ‘phone number’ field, just ‘model’, ‘IMEI’, ‘ confirm IMEI’ and ‘remarks’.

    I’ve tried both IE and Firefox.

    The certificate I’ve made without filling in the ‘phone number’ field doesn’t work (‘constrained certificate’ error while installing apps.)

    Weird, right? Did our Chinese friends change their website or is something else going on?

  48. raj says:

    I dont know but what do you think should be done? well i tried removing the battery i heve reset factory settings but still not working? can u plz help. eagerly waiting for ur reply.

    • sony says:

      this is not the problem with the OPDA certificate it may be a problem with the memory or you may install incompatible application, so once format your mobile, formatting your mobile erase your phone memory so take a backup and format it, use *#7370# to format.

  49. rog says:

    hi sony,

    i followed your instructions and used the opda cert and key to sign the apps using freesigner but i sill get “certificate error”

    would you know why this is still happening?

    • sony says:

      I also faced the same problem but most of the application have no certificate error after resigning. If resigning won’t work then follow manual installation with the original file.
