Mẹo vặt và kinh nghiệm sử dụng dành riêng cho dòng máy Symbian OS9 v3

[hechang]

+ Thời gian gần đây, các máy sử dụng hệ điều hành Symbian OS9 đã rất phổ biến. Mặc dù cùng thuộc dòng Symbian nhưng đây là phiên bản mới với nhiều tính năng nổi trội và kèm theo đó thì độ bảo mật cũng tăng lên rất nhiều o với Symbian 7&8...Do đó, để có thể can thiệp sâu hơn được vào hệ thống chúng ta cần phải dùng một số mẹo vặt và kinh nghiệm của những người đi trước.

+ Tôi mở topic này để chúng ta cùng trao đổi các kinh nghiệm về vấn đề nêu trên, chỉ dành riêng cho Symbian OS9. Mọi bài viết lạc đề, thắc mắc không đúng chổ...đều sẽ bị xóa mà không cần báo trước, cũng không cần giải thích. Mong các bạn ủng hộ và hợp tác.

Interpreting Signing Error Messages in S60 3rd Edition



Message: Certificate error. Contact the application supplier.

Hint: You may have tried installing unsigned application. Note that signing is mandatory S60 3rd Edition. You can use self-signed certificate or developer certificate from Symbian Signed to sign your application.


Message: Unable to install. Constrained by the certificate.

Hint: This message pops up when you attempt to install developer certificate in the unsupported device. The developer certificate from Symbian Signed can only be used in a limited number of devices. Remember that you have to send your IMEIs to Symbian Signed when requesting certificate. You cannot use the certificate in other devices that is not in your IMEIs list.

Message: Required application access not granted.
http://www.antonypranata.com/articles/images/access_not_granted.png

Hint: Check that your certificate can be used to sign all capabilities needed by your application. For example, if you use self-signed certificate, you can only sign basic set capabilities, i.e. NetworkServices, ReadUserData, WriteUserData, LocalServices and UserEnvironment. If your application requires one of the extended capabilities, for example SwEvent, you cannot sign it with self-signed certificate. In this case, apply for developer certificates from Symbian Signed.


Message: Unable to install a protected application from an untrusted supplier.
http://www.antonypranata.com/articles/images/untrusted_supplier.png



Hint: If you use self-signed certificate, make sure that your application uses unprotected UID, i.e. 0xA0000000 - 0xAFFFFFFF. If you use protected UID (0x20000000 - 0x2FFFFFFF) or legacy UID (0x10000000 - 0x1FFFFFFF), you will get this message.

Message: Unable to install.
http://www.antonypranata.com/articles/images/unable_to_install.png




Hint: This message may come up when your installation file (.sis/.sisx) copies files to other application's private folder, i.e. \private\uid. Note that Symbian 9 introduces data caging concept, it means you don't have access to other application's private folder.


In case of expired certificate...
Do this...
Set the phone date back by 7-8months...
Than install the app...
After doing that reset the date back to routine...

If still the problem is present...
In that case your certificate has expired...
Get a new certificate from symbian signed...
As the certificate got from symbiansigned are valid only for 6months...

TRICK to RECORD from VISUAL RADIO


100% WORKING


You must do the steps I write:

1. Install Ultimate Voice Recorder
2. Run Visual Radio via loudspeaker and set the biggest volume for best result
3. Run Ultimate Voice Recorder, for best result choose the wav format
4. Press record and set the biggest volume
5. Now you'll find it very easy to record audio from Visual Radio

Basically Ultimate Voice Recorder is great recording application which can record every sound, not only sound from Visual Radio or internet radio but every single sound that your phone emanates and sound comes around your phone. That's why, before recording make sure your surrounding is quite.
I don't know with another recorder, maybe they can record from radio too. I also attach a recorded files from Visual Radio in wav format as a sample.
Have a try! Hope that this will help people a lot.
