How To Get Our Own OPDA Developer Certificate And Key
sony | May 25, 2009 | Comments 119
In this post i would like to tell you how to get an OPDA developer certificate for our symbian mobile from opda. First let me tell you how it can be useful to us? This OPDA certificate and key file lets us to sign unsigned applications.
Okay! Coming to the procedure, opda is a Chinese site, that’s why most of the people feel difficult to get a certificate from there. I am going to give you step by step procedure to how to register and how to apply for the certificate and key with screenshots. If the image view is not clear then click on the image to zoom.
Step 1:- Register an account at OPDA from here.
An agreement forum will open in china, just scroll down and just click on the left button as shown in the following screen shot bellow.
Step 2:- Here the actual registration from will appear as shown in the screenshot bellow.
Fill it as in the screenshot bellow.
Step 3:- After the registration we need to apply for our certificate and key, apply from here.
Apply for them as shown in the screenshot bellow.
Step 4:- After few hours, check here for your certificate and key file.
If nothing appears, it means it is in progress.
They took 2 days for my certificate and key files.
Download them and sign the unsigned files with your own.
To sign the applications we need a signer, you can get it form here.
You can use any key in the key filed of SIGNSIS- GUI.
If you encounter any problem, just have a look at the comments bellow. You may get some information to solve your problem right now.

http://www.opda.net.cn/logging.php?action=login
Kzmoks, it seems to be you are not loged in, so login first and then follow from step 3. In step 3 after clicking on “here”, you need to enter your IMEI no in the first box and then enter 13 followed by any (preferably last ) 9 digits of your mobile number. After that follow step 4.
If you are facing any login problem, just leave a comment here.
All The Best Kzmoks!
Please help me anybody! After doing everything, as soon as I want to enter my IMEI and 11 numbers, it returns an error message – Duplicate IMEI detected. I didn’t enter yet the IMEI, maybe somebody had stolen my IMEI. I can’t do anything, please help me, where to get certificate, or how to make them give me another one!
Thanks in advance!!!
plz sony…
i still cant login
i cant change webpage into english
Just go to http://www.opda.net.cn/register.php
There click on “English”, a page will open.
Then observe at the top left, two boxes can be seen. First one is for user name and the second for password.
After loging in don’t close the page, keeping it alive just go to the my certificate page.
Thanks sony, I got my certificate after 2 days & now I can sign my unsigned applications. Thank 4 the nice detialed instructions once again
I am in the process of getting my cert I am a blind computer user how eexactly will I download it when the to links appear?
Hay that’s not a big deal my buddy, just click on them to download.
Now to obtain an OPDA certificate it takes more than 24 hours. I’ve been waiting since yesterday and i still couldn’t download the cert or the key. Seem like there are lot of members registered and to process all of this IMEI’s it takes much more time. I had two accounts but one ran out of OPA’s. There i could download 4 certs and 4 key files and after that it’s not possible to download even a single cert or key file due to lack of OPA points. What shall i do regarding this issue? Does anybody know how to increase our OPA points without posting anything in that site??
What is it all about that thunder application which they provide us free of charge to download certs?? Have you got any idea about it?? Is there an any other site where we can get this crucial certificate files??
Where else can i get 17 cap certificates??
Thank you!
its coming up on the third day sence I have registered and applied for my cert, should I get it soon… I do not think it should take this long
It depends on the no of cert requests but i can say it is worth waiting.
Hi, Sony. Please, Mobile No .. what is that mean? Like my phone number or last 9 digits from IMEI? Please help, thank you
last 9 digits of your mobile number.
I have applied on 17th of june and still nothing!!!! It’s been more than 3 days now. ….the bloody thing is still red. is someone else experiencing the same ?

Hey Sony, do just gor my certificate and reg key today. Do I istall it onto my pc or transfer it onto my phone and open them there?
The reg key says something about adding on to my computers registry, will it harm my computer?
Hello, New Nokia Owner. Just save them on your PC and you can also transfer them on to your mobile too.
Basically these files are required to sign any unsigned applications, it can be done on our PC as well as mobile (using mobi signer). To sign we need the unsigned source file and these certificate and key files.
thanks,
icould submit the request,
please tell me how to follow up,

Hello Matanglawin, the key and certificates are allowed to download for a period of time, i have downloaded my files after some days i am also unable to download the files.

Matanglawin, we need to post some articles on their portal.

Hi Giwin Mathew, they only allow us to download the cer and key files for a period of time and we can’t request for the same IMEI no.
Hello i rember requesting the certificate in FEB 2009 but can i get it from there ? i dont rember my login id . can u create me an account at opda ? someone pls help. THANKS IN ADVANCE .
Hello i tried requesting for my certificate again for nokia 5800.in case i dont get it what should i do pls tell me how to install unsigned apps. i heard that there is a hack to install unsigned apps but will it harm my n5800 or will it void my warranty? pls answer my query? can i get the certificate from somewhere else? THANK YOU
Giwin Mathew, We can get a certificate from the people having a publisher ID at symbiansigned.com. Generally these people are the developers.
We can hack our mobile to install unsigned applications. No damage will occur, if you format or update your mobile then the hack wont work and you need to do it again but there so no guaranty to work(hacking) after the frimware update .
Search our portal to get the hacking tools at http://mynokiamobile.org/2009/05/21/hack-component-is-built-in/
Hi, i have applied for opda certificate and it had been processed. i am unable to download it. it is asking for a thunder client to be installed after clicking on the cer or key links. i got it installed it but i was unable to download it please help me. thanks in advance, srikanth.
Hi Srikanth, are you sure that your cer and key are developed?
Have you downloaded ever before. And one more thing is that We don’t need to install any applications on our PC. Explain your problem in detail.
Sony thanks alot !!!!!!!!! Anyways i got a certificate & key much faster than OPDA from another website. i got the certificate within 1hour of registeration. wow the site is cool & process is much easier.
hi soni, i am certainly sure that my cer and key had been generated. this is my first download. the links for cer and key are very much appearing in the download section in red colour. when i clicked on key it redirected me to install the thunder client whose name is “webxl_32784.exe” got installed. after opening the thunder client a window appeared in chinese asking for the save location. here clicking on the OK button located at the bottom i got the cer and key files now. just now my problem is solved after long try. thanks for this wonderful resource. I am using I.E 8 and this is the procedure which i followed. further any one who had used thunder may please explain clearly as i am not very good at explaining. i have followed the following link for help on thunder.
http://www.opda.net.cn/viewthread.php?tid=188102&pid=3149111&page=5&extra=#pid3149111
thanks
sri.
Hi Sri, by this time i have understood your problem. And we don’t need to install the thunder client, if the certificate and key files are visible to you then it indicates that the cer and key files has been developed for you, so just click on them to get them. No problem with the browser.
hi, Mathew could you please mention what sight it was which gave cer and key to you with in 1 hour.
thanks in advance.

Hi:
I was downloading the files but only got the Cert file. It would not download the Key file. It said: execeeded something. tried using the cert file but I receive an error when installing the software. I am using Ffree Signer installed on my phone. Any help?
Opda may have a strategy to not to allow the people to download the files after a time period. Try my latest post http://mynokiamobile.org/2009/07/05/how-to-get-a-certificate-and-key-files-for-nokia-s60-mobiles-in-hours/
