Nokia 5800 “Expired Certificate Error” 100% Working Solution
Just a couple of days before,I bought Nokia 5800,popularly dubbed as Nokia’s answer to the Iphone.When I tried to install application on the phone,I was greeted with an unpleasant warning “Expired Certificate”-and I was not able to install a single application.Going through forums I came across the old way to set my mobile’s date to a back date.But it didn’t work.
Again after losing some hair strands,I came across the working solution to the problem.Here it is.
Format your phone to fix “Expired Certificate Error”
I tried to rest my phone to factory defaults.Even it didn’t work.
Then it was time to give my phone a hard shock by formatting it.Here is how to do it.
Step 1:backup your phone contents.
step 2:Removing your memory card is recommended.
step 3:Enter the code *#7370# on your dialer screen.It will ask you to continue restore.Say a big YES .
step 4:IT will ask you a security code.By default it is 12345 .Enter it and you are done.The phone will restart.And your problem is gone..
I have tested this method on two Nokia 5800s. and this method WORKS.If your Nokia phone is giving you certificate nightmare then just try this method .Once you do this you will be able to install all fantastic application available for this phone.
If you have also solved the problem using this method then just let me know in comments.

Hey.. do you know how to mute my camera shutter for nokia 5800??
i think my firmware is version 20… anyways another thing that is is it because the app is unsigned??
@Nathan:At present the latest firmware for Nokia 5800 is V 21.0.025 available for download at Nokia’s site.
There may problems in installing unsigned apps so always go for symbian signed apps only.
I have tried this solution twice and some other websites have mentioned choosing HONG KONG as a location i did and then i switched it back and believe me this doesnt work i have great applications that cant be installed…
plz help me
@wizmaster:Let me know which software you want to install.Are you able to install any signed application or not?
This is the worst step that anyone can rely upon. It never works !!!!!!!!
@Dfunk:To be honest,resetting a mobile is indeed a bad idea,but when you try traditional methods such as changing the mobile date/location and fail,this comes to the rescue.
And Moreover I have hand tested it on my own Nokia 5800 and then on my friend’s phone.At both times,it worked,hence i can safely say-It Works!!!
