Certificate Error..Nokia 5800XM

[188007]

I recently bought Nokia 5800XM. When I am trying to install apps, many of them installs fine but I am getting an error on few of those while installing them ...The error is "Certificate Error. Contact the application supplier"...What to do? I have read that the mobile has to be hacked ...But I havent understood how to hack it..Can anybody tell me properly how to sign apps n hack it?

whats your firmware version nos. upgrade to the latest one and ur problem will be solved.
or if you do not want to upgrade then check the forum/discussion site @ nokia europe for the workaround.

i guess it wont be called hacking,..but you will have to sign your own apps (the ones which are not signed already)

i dont know whether it is legal/illegal to do so,..

here is a guide for signing your own apps:

Its 11.0.008...

When I am trying to update, it says its the latest n there is no update present. I saw that v20 has been released. But I dont know why isnt it updating.

BTW Will updating solve the problem surely?

yes updating will solve the problem.
if u cannot wait for the update then try the soft reset method.

1) Backup all your Data with Nokia PC Suite.

2)Disconnect from the pc

3)Press the on/off switch briefly and u will get a menu, scroll down to "Remove E:Memory card" click on it and wait, then you will be prompted to remove the memory card, remove it.

4) Open the dial pad and type *#7370# , your phone will do a software reset and restart.

5) The default phone lock code is 12345, enter it if the phone promts you.

6) Enter ur location , data /time etc.....

7) Switch off the phone and reinsert the memory card.

8) Switch on the phone , wait till the phone initialises the memory card and then try installing the programs again.

NB: Warning: There is a chance that you may loose ur DRM licences and all ur pre loaded songs may get locked. so do the above at your own risk.
