If you are using a Nokia Phone which has a symbian operating system then you must have tried to install an application and failed because of : Certificate error. Now your problem is going to end soon as i am going to give you a way to install any unsigned application on your symbian device. I hope you all will like it.
Recently, I posted an article about how to hack nokia E71 and install any unsigned applications on e71fanatics.
Well, hacking Symbian devices are not very difficult task to do. I know you all must have tried to Google it before reading this post and must have found many ideas and ways to hacking your phone but the way which i am going to show you is the most easiest, permanent and the most secured way i would say.
Admin warning : Hack at your own risk. I am not liable for any loss or damage.
So, before making you much wait, I start the proceedings. I try to make it as easy as possible so that you all can understand it without any haze. I note down and explain each and every point perfectly and list down the things you will need. Note one thing that the information you provide about your phone will be secured.
Things you will need :
- FreeSigner
- HelloOx2
- OPDA account
- Patience !
- Get an account on OPDA and login to it. After redirection, Click on apply cer.
- Fill in your all information about your phone in those appropriate fields as asked. You will be given a confirmation message after a successful submission.
- If you submit your application for certificate successfully, you will get your certificate and key which you will need to download from logging in again.
- Download FreeSigner and install it in your phone.
- Download HelloOx2 and save the file in your phone. Remember : Don’t Install.
- Now get your certificate and key from OPDA and save them in your phone.
- Open FreeSigner and go to settings and map your certificate and key in those appropriate fields. Go back and select Add Task and map your HelloOx2 file there which you saved as referring to point number 5 above !
- Now press option > Go and wait for a moment. Now go to the drive where you saved your HelloOx2 file.
- You will get a new file named HelloOx2Unsigned_Signed. Now install this file and Restart your phone.
- After a restart, run the application and wait for some time ! You will get a confirmation once the process is done !
This is It ! Now your phone is ready with a firmware hack ! You may install any unsigned application you want !

How To Hack Nokia Firmware And Install Any Unsigned Application !…
easiest trick to hack your symbian firmware and install any unsigned application !…
Thats what am trying to say. The stability factor, freesigner worked on all firmware updates. Moreover, there are warranty issues.
NO dude ! there ain’t any warranty issue ! I had my E71 cracked firmware and then just yesterday i went to nokia care and had a firmware update install without any cost so that suggest that it does not void the warranty at all
If you format your phone after installing HelloOx2, it will perform as if it has not been cracked 
HelloOx2 doesn't work properly on all devices. Makes 'em hang sometimes. I, too, wrote a similar post and suggest use of freesigner. Moreover, things aren't clear as to whether warranty is void on hacked handsets or not.
Thank you for reading the post, Paritosh
Thank you !
Before writing this article, i have checked this trick completely and i have successfully cracked almost 16 symbian devices with HelloOx2 including my 2 E71, Nokia 5700, Noki 6700, Nokia 5800 without any difficulty ! Hello Ox2 is the most trusted firmware hacking software available which is not a free software as you can check on your site and about your hanging issue, HelloOx2 is being updated every month and if a new firmware relweases after an update, HelloOx2 will not support that firmware. For more details about which firmware does it support, you cal check in the paid version on their official site
OPDA site not working
To be fair with you, i did manage to hack Nokia 5320, Nokia 6120 Classic and also N79 with HelloOX2.
Well done!
thank you for that ! but my concern is about your E63
it must work dude :S
Hi Rahul,
For your information, i am hacking Nokia E63 because i would like to install a screen reading programme. If HelloOX cannot be installed properly, then i will not be able to run the Rom Patcher to complete my installation.
I have tried hacking Nokia E63 with HelloOX, but unfortunately, when i attempted to run the software, The "unpacking files" on the screen keeps on showing for almost an hour. bored with the situation, i closed and tried again but a similar scenario occured. Does it mean that Nokia E63 cannot be hacked with HelloOX? Where have i gone wrong?
well, all firmwares of E63 are supported !! so just check you might be making mistake in self sign sis or sign sis otherwise i think it should work for sure

Hello Friend,
I’m having Nokia 5230. I was successfully do the above things and i’ve got success too. I was very happy. But the next day i updated my phone’s firmware in Nokia’s software updating via my internet. After that The HelloOX2 and Rom Patcher was not worked in my phone. Pls help me i’ll be thankful to you. My current firmware details are follows
Sw Version : v 20.0.005
SW Version date : 23.03.2010
Custom Version : 20.0.005.C01.01
Date : Same
Model : 5230
Type : RM-588
Well Arun, I am sorry but i would say that you made a mistake by upgrading your Firmware
HelloOx2 for 5230 supports firmware till 12.0.089 ! So now i advice you to go to nokia care and ask them to downgrade your firmware. If they do that, you will be able to use it again

Ok rahul!
Is there any chance to update the helloox for the newer version firmwares. Dear Hackers help me. I’m tired of signing the programs via pc.
No ! It is just that helloOx2 is not available for some of the new firmwares yet
so better degrade your firmware to older version

Is it possible to change symbian to android on nokia c6
Plz Help me Rahul
thank you very much for the detailed instructions, but opda stopped issuing certificate. Any other source to get certificates.
please remove that post or write something about that getting certificates are now impossible. so try any new idea.
Thanks
Hi Rahul, OPDA is taking a looooong time to issue certs… maybe they do NOT do it anymore, like kishore says?
Also, FreeSigner shows "certificate expired" and would NOT install.
I am going to go to Android for good.
DAMN NOKIA. Cannot install all the good stuff. No wonder it has lost the mobile war.
