WORKAROUND
CAUTION: This fix will erase everything in your phone memory – messages, contacts, settings. Back up your data before proceeding.
Do a software reset. From the Dialer, enter *#7370#. You can now install apps again. Crude, but it works.
WORKAROUND
Ok, so I got this phone last Saturday. Sunday, downloaded some odd number of themes, put them on the phone’s memory card, and installed 3 of them. Installation went fine, and the phone is currently sporting a non-Nokia theme.
So, Monday night (last night, dummy), I tried installing the other themes, but I got the “Expired certificate” error message. Thinking that it was a problem with the theme installers, I moved on. Checked the Nokia Download! app on the phone, and tried installing IM+. After downloading (weird, on first download, after reaching 93%, it went back to 0% and started downloading again), the phone displayed its “Preparing installation”, and after a few seconds, “Expired certificate” appeared.
Nokia is in for painful headaches. Look at this thread and see some problems being experienced by other owners of this phone. I wish Nokia luck.
When you try the Nokia Download! service using your Nokia 5800, you will be shown folders where you can find apps and ring tones and graphics. So I was curious enough to check the Apps folder, and whoah! Several applications, all marked as free!
So I tried downloading IM+ (which led me to that expired certificate error last night) earlier via Smart 3G (Smart’s HSDPA at Makati is good). Too bad it’s not really free.
After downloading, the phone began installing the app, then I was prompted to select what license to PURCHASE. Yes, you have to purchase a license to use the app. Yes, it is free to download. No, it is not free to use.
Nokia Download! ain’t Apple App Store. Try harder, Nokia.
And no, Nokia Download Store is not available here in the Philippines. Yet.
Just tried the Nokia Barcode Scanner app. It works as advertised. The app is not included in the package, so you’ll have to download it here.
Yesterday, the charger for my Nokia 5800 XpressMusic broke down. I was able to use it yesterday, and several hours later, I checked on the unit. The phone battery meter was full and was not moving, indicating that the charging was complete. So to verify, I had unplugged the charger and then plugged it back. Nothing.
Tried charging at home – nada. Tried charging an officemate’s phone earlier – nada.
Time to visit Nokia Care. Almost a month after I bought the phone.
