Step 2) Select drive C: or D: depending on the memory in which the Sms messages have been saved.

Step 3) For example u selected c: , Then open “system” folder.

step 4) Then in “system” folder open “mail” folder.

step 5) Then in this folder u will see different folders (eg 0010001_s) and certain files (eg 00100000). These files are the actual messages. Browse through every folder and open all files till u get the sms u are looking for.

Step 6) For opening the files don’t choose options>file>open as it will show format not supported rather choose options>file>hex/text viewer. By selecting the “Hex/ text viewer” u ll be able to open and read the deleted SMS message

Remove the microSD memory card.

When the phone is powered on, don’t simply remove the memory card. Otherwise, the memory card content will likely corrupt.

For past few days, I’d been busy finding workable solution to the annoyed “expired certificate” problem that happen when I attempt to install SIS/SISX program files in Nokia 5800.

There are forums and blogs mentioned that the version 10 firmware is well known for this “expired certificate” bug and thus should upgrade to the latest firmware version 11.0.008.

However, my Nokia 5800 firmware is already at this latest version out of the box. So, what’s next?

i had purchased my new nokia 5800 set.and i was really disappointed when i saw all this crap.i was like what the heck man.what is the use of this set when i cant even update or install anything.i was really disappointed but then i got something interesting to fix this crap and here it is to share with you

But now, I’m pleased to tell you that I’ve fixed this “silly bug” at last try,

How to solve the Nokia 5800 “Expired Certificate” error that fails most SIS program files installation?

To be frank, I just don’t believe that one-line reply could be a real solution for me. But, I’ve ran out of ideas and found nothing newer than his suggestion.

So, I simply take it as last resource to try. Eventually, this simple trick does works magically, and I can’t wait to tell him how excited and grateful I am!

For reference, here is the solution in detail
(in case you’re not sure what additional steps I’d done on top of his one-line guide):

Backup all messages, notes, calendar entries, and contacts.

To remove the microSD card when the Nokia 5800 is switched on, press the power key (the button next to the power charging port), scroll down to locate and select Remove Memory Card, opt “Yes” as the “Removing memory card will close all open applications. Remove anyway?” message is displayed.

Shortly after, the “Remove Memory Card and press OK” message appears, and then the microSD is ready to be unplugged or removed from the dedicated slot.

Notes, both SIM card and microSD card slot are next to each other on the same side (another defect, personally), don’t be careless and end up corrupting the SIM card (if you happen remove SIM card instead of microSD card).

Format the Nokia 5800

Access to touch keypad and enter *#7370# secret code (not so secret, anyway) to restore phone settings to factory default (even the user data and files are deleted).

Next, you’re prompted to enter the Nokia phone lock code. The default is 12345, if this code hasn’t been changed by yourself or any one.

Then, the phone restarts and you’ve to select the country region (just select your own country from the list, in this case), followed by request to enter current date and time.

When the phone is ready, power it off again to re-insert the memory card (for highly safety measure, unless there are nothing important kept in the memory card, e.g. picture, music, documents, etc).

As the phone is switched on again with memory card inserted, the “preparing memory card” message appears.

Finally, I’m happy to be able install all my wanted Nokia 5800 programs and games without getting the “Expired Certificate” error message that says “Certificate may not yet be valid, is expired or phone’s date setting may be incorrect”

Tip 2: Decrease brightness of the display
If you have an option to decrease the brightness of the display then choose a level which has medium brightness and not too high. Nokia’s smartphones light sensor helps adjust your display brightness according to the external lighting conditions, so keep it switched on at all times.
Also when running short of battery, do not waste battery by turning on the display for unnecessary purposes. Also when you know you will be away from a power source for a long time, reduce the brightness of the display to minimum.
Another handy tip is that you can reduce the time of back-light duration according to your need.

Tip 3: Disable vibration and ringtones
Vibrating alert is a feature that uses a whole lot of battery life, so disable it when you do not need it. It really sucks up battery life fast so do not use it when short of battery life.
Disabling ringtones in an emergency situation is recommended to save a bit of your battery life. Also use low volumes on the ringtones as the louder the ringtone, the shorter the battery life.

Tip 4: Close unwanted applications
In a smartphone various applications keep running in the background which utilize your phone resources which all use of your battery. So check for any unnecessary applications that might be running and terminate them. Music,videos,GPRS are very demanding on the battery so avoid using them when low of battery power.

Tip 5: Turn phone off when no network
When you are in an area where your mobile provider has no network or the place has cellphone jammers installed, switch off the phone. Your cellphone continuously searches for the signal which uses the battery very fast. This is applicable when you walk through long subway or drive in underground tunnels. If your phone has an offline mode, then use it to good effect in such a situation.

Tip 6: Charge and discharge tips
This one is very important in the long run. Many of us tend to charge the battery when it has been used only midway. This is not a healthy for the battery as more charge/discharge cycles on the battery means lower battery life. Charge the battery only when you are low on power. Also it is recommended to fully discharge the battery once a month to ensure its proper functioning.

Tip 7: Battery maintenance tips
It is important to take care of your battery. It is very important to keep your battery away from moisture as it can severely damage your battery. So take care of it in rainy season especially. Also do not bring it near high heat which is harmful for the battery.
When you do not intend to the use the phone for a few days then remove the battery and store it in a cool and dry place. Do not play around with the battery as a shock can render it useless.
These tips can go a long way to help you increase your battery life. Have any other tips? Go ahead and share them with us.
