Solution For Certficate Error in Nokia Symbian S60

The most common problem for NOKIA symbian phone's is "Certificate Error" while installing Applications. You can get your app signed online at SymbianSigned but they don't sign all applications. Finally on searching online i found a Chinese site OPDA. They generate 'certificate' and 'Key' for you which can be used to sign any application. Site is in Chinese so i had explained it here using pictures below.
STEP 1 Click here to Register. A countdown from 10 will start at end of page
then click left tab which means agree, see image's below and follow procedure.
































STEP 2 Page will re-load and take you to home page. If not click login next to Register.
































STEP 3 After Logging, click Certificate System under Facility.














STEP 4 Enter IMEI no. in first box you get by dialing *#06# 15 digit.
In Second Box enter your phone no. should start with 13, 15 or 18 total of 11 digit.
After successfully submitting you will be redirected to my certificates. All certificates you had applied for are listed her.

















STEP 5 After a day probably login back to OPDA(step 2) goto Certificate system (step 3) download cert. & key under DOWNLOAD section.

ONCE you got your Cert. & key use SignSIS to sign your applications, download it here.

IMPORTANT: There are lot of forum's which take cert. & key generation requests just to make more members and earn revenue from ads, use this procedure to get cert. & key free.
