Get your own developer certificate NOW.

As most of you already know, SSS (Stupid Symbian Signed) have revoked the end user's ability to attain a developer certificate, forcing us to use their open-signed online system. This of course meant that ALOT of freeware was unable to be signed... until now that is; read on to become liberated!

First of all, I'd like to thank MORF of the Symbian Freak forums once again, if it wasn't for him many thousands of Chinese-illiterate people would still be without certs.

Read ALL instructions and click ALL pictures before attempting

Head over to OPDA clicking here.

Click on the register button at the top right corner of the page.

Fill in the registration form as shown in the image below (Click for full size):
Once you've registered, log in and click on the large orange 'apply cer' button. Fill in your phone's details (you can find your IMEI number by typing in *#06#):

Wait for about a day and then log back in to your account. Click on the 'My Certificate' link and check to see if your certificate is ready:
If it's ready, there'll be a big green tick. Now you can download your certificate and key files.

Things to note:

  • Posting your IMEI on the internet may be dangerous depending on where you live.
  • It may take several days before you receive your certificate, OPDA generate certificates for thousands of people per day.
  • You MUST keep the key file and certificate file safe as they're directly linked, I recommend emailing them to yourself or keeping them on some flash drives/memory cards.

    dude, i love you. Thank you so much!

    Glad to have been of assistance :)

    Great, thanks!
    Just one question; ive posted my imei and such, still have to wait a few days to receive mine, but I've downloaded one of the previous .rar files, and it only contains 1 certificate and 1 key file. These files are, as said, personal, but how can they be if a 1000 people can use it for 1000 different imei's?


  4. G.R.G.

    Marten, yes there's only 1 Cert and Key in the rar. I don't know how they do it because like I've said, sometimes they have 3000 IMEIs in 1 certificate.

    It does 100% work, it's just that you're sharing a cert with many people around the world.

    I know that probably wasn't explained to well so if you have any more questions just comment again.

    Thanks mr-x! It wasnt really that I needed an answer, just a verification that the system really works. I've been browsing the net for over a week now to try and find a bypass or dev.certificate for ss, with no luck, until I came here! About 7 more days should do it..
    Thanks alot!!!

    Ever tried to think of it as identity thieft? These guys are collecting thousands legit IMEIs for unknown purposes. E.g. Don't get suprised finding your phone banned in your operator network as stolen... or false emergency calls (e.g. a "bomb in the airport" call you'll be responsible for) originated from "your" mobile in Sim-less mode...

  7. G.R.G.

    The only way to report your phone as stolen and get it barred that I know of is to call your operator. What you're saying is that these people at this forum are gonna get people living in the MANY DIFFERENT COUNTRIES that these IMEIs are coming from and then 1 by 1, using a different phone number each time for over 50,000 IMEIs report the phone as stolen.

    Check the other threads in the forum, these guys aren't trying to harm your phone, they're trying to make it YOURS.

    Besides, if my phone does get barred, I think I know of ways to change the IMEI.

    Thanks for the comment ;)

    OPDA seems to have removed the Text Entry Field

    Once you've registered, go back to the page we started at and scroll down to the bottom where you should find a text entry field. Fill it in according to the image with your IMEI & Date of Application.

    Request you to modify the guide to suit the Re-designed Website

  20. Anonymous

    I see. The hack didn't fail you, it's just that for you to be able to install unsigned applications, further steps must be taken (Manually placing the installation files in their appropriate locations) but hopefully, there'll be an easier method, if there ever is, you know where to look.

    Cool, it took me just 12 hours from finding this web page till getting my ReadDeviceData-using application signed and working on my phone.

    Thanks a lot, Mr.X.

    What I'm wondering about is why OPDA is doing this? Pure generosity or they can somehow make use of the obtained EMEIs? ...

  22. Anonymous

    Hi Konst,
    OPDA (as far as I can tell) are doing this out of generosity. I think it is possible to somehow use the collected IMEIs to create cloned devices but that's simply the risk we have to take for Symbian liberation!

    I'm glad that I could help and thank you for commenting!

    Hey Mr-X, I've got a question...

    As soon as I get my certificate and key file...

    What do I with them to sign my .sis files? How do I apply the certificate into .sis files or sign them with the certificate I get?

    Thanks and congratulation on your great work!

    Nice one, waiting for my file :)

    Great Work....

    BTW. I think it would be nice to pinpoint out were the login for the forum are, and were you find your file when you need to login again after a days time.

    Anyway, it didden't take so much time to find out, but would be a nice edition anyway.

    Thx a 1000 times, can't wait to see my phone cracked. (just got it:)

    I think this also doesn-t work. No one even in other sites can make this work. I think we know have to wait for someone to discover a new way to get a dev cert.

    it keeps on saying invalid email address no matter which email address i type in..

  68. yourBuddy

    Do NOT enter your email address below the IMEI box. Just enter any random 11-digit number starting with 13, 15 or 18 as instructed and it will accept your IMEI.

    There has bee an update on the 11-digit number... Doesnt work anymore :-)
    Could you, who knows the site, check it out?

    My bad, after X tries it went through :-)

    Thanks for a great guide for a starter.

    I followed the guide and got my download link. Great! Downloaded the first file and was about to download the next and was told (had to translate on google) that i was missing OP points or something?

    As already mentioned above the OPDA website has been updated and there is now an 'English' option. My problem is that it says that my phone number is wrong. I assume it something to do with your 5th screencap and the number beginning with 13,15 or 18

    Hopefully you can update this guide with what we need to do or suggest some other way to ge the certificate

    All the best
