The 5800 can t install the JAR software, but the sisx can

Your memory card is problematic again, first back it up, then format the memory card, if it still doesn't work, the memory card is defective.

It should be a memory error only for grid machines.

Surprise the University of Technology!! Is the University of Technology also using 5800?

I'm here to watch the University of Technology...

Professional mobile phone certificate production, mobile phone cracking Look for Brother Xiaosheng!

The certificate expires because of your date problem, and you get a prompt that after the certificate expires, you adjust the time of your phone to 09 years, or it expires in 08 years, and it expires in 07 years. These 3 random vintages are fine. Good luck with a speedy and successful installation. I don't understand yet that I can add questions.

Two reasons.

The jar file is corrupted.

jar file You use the Chinese name to change it to letters.

Change the name of the jar file to a letter

5800 is the S60v5 operating system, sis sisx can be installed, sisx just has one more signature. If you can't install it, you can check whether the software you need to install is signed or get a certificate yourself. Then sign the software that needs to be installed and prompt a certificate error or something, and you can install it by signing it once.

Also, it depends on whether your own phone has set the software installation to no. Go to Program Management, right-click Settings, Software Installation, select All, Certificate Check, Turn Off, and Other, Default. Try it, if it doesn't work, you can only press what is written on it and get a certificate yourself, and you can press any software.

Enter the initial password 12345

That means your phone is a parallel import.

What is the specific phenomenon? JAD files are generally not used to delete directly, unless specifically stated or the direct installation of the jar is unsuccessful. The vast majority of JAR software can be installed, but some software packages that do not support touch screen can be installed and cannot be used, and a very small number of software packages cannot be installed due to problems.

The Nokia 5800 is based on the S60 V5 system and supports software in SISX format.

Maybe your phone doesn't support it, it is recommended that you check the tutorial on the Internet.

Use a data cable to select the mass storage mode, copy your SISX and SIS, JAR to the install folder of the portable hard disk... Open your phone - Applications - Office - File Management - Mass Storage - Installed Files, find the program you want to install, double-click with your finger, OK! If you have time to go to the x6 forum, there are fun software that you don't expect, hehe!

You have copied it into the hidden directory, connect your phone to the computer with a data cable, and open "My Computer". In the settings options, set "Show hidden files" to "No". Then the folders that are displayed are OK.

Generally speaking, Nokia can automatically identify the installation files on the disk, and you can install them directly, unless it is not a complete installation file at all.
