(SOLUTION) INVALID CERTIFICATE OR Certificate not on phone or SIM - for NOKIA S40 phones
I've suffered from this problem (I have a 2700c) and I have come across many similar situations.
So here is a guide (Reasons & Solutions) to help
you solve this problem.
1. Deleting the certificate manually from security
2. Getting your phone flashed at an unauthorised
repair shop. It is not recommended to do so for
it voids the warranty, it deletes all the certificates
from the phone and you may end up with a
1. Update your software using Firmware Over
The Air (FOTA). If there is any update available,
certificates will be sent on your phone -
download & then install them.
2. Try reinstalling the firmware using Nokia
Suite/Nokia PC Suite. It will install the genuine
software for the phone and along with it the
certificates will get installed.
3. If nothing works please contact an authorised
Nokia Care Centre that is near you.
For firmware reinstallation/update (Guide &
Things to remember)
Connect your phone to a computer & select
Nokia Suite mode. If you do not have Nokia Suite
on your pc you can download it from NOKIA.
Now open the Nokia Suite & click on the Ã¢ï¿½ï¿½green
icon of arrow pointing downwardsÃ¢ï¿½ï¿½.
If any updates are available they will be shown in
Ã¢ï¿½ï¿½greenÃ¢ï¿½ï¿½. If not you may reinstall the current
version. Reinstall option is shown in Ã¢ï¿½ï¿½blueÃ¢ï¿½ï¿½. If no
option to reinstall is shown, please wait for
sometime it will become visible. Then the Nokia
Suite will download the new software version of
the phone. After it you will be prompted to take
a complete back up of the device content. Please
do not skip this step as reinstallation will erase
all the personal data from the phone like
contacts, messages, calendar entries etc.
Please note that if you have set a memory card
password & you have forgotten its code then
take a backup of the card data also as the card
will be locked after update and can only be
unlocked if you enter the correct code or by
ways mentioned in this thread.
Also note that while updating the device ensure
the following things-
1. The device is full charged.
2. The internet connection Is of good speed &
has a backup in case of power loss.
3. The PC should also be connected to back up
power source as if the process is interrupted
the phone may go dead. More on update
failure & its remedies here.
4. Please do not run any resource intensive
programs in the background while updating
as it may freeze the PC which in turn will
lead to a dead device.
5. Ignore all the windows pop-up notifications
about device being disconnected. DO NOT
DISCONNECT THE PHONE UNTIL
UPDATE IS COMPLETED.
6. It will be better if you disable security
keyguard & PIN code request before
proceeding with Update/Reinstallation.
7. Sometimes the device may show Test
Mode. Do not panic & DO NOT remove the
cable. Let the process complete. YOU CAN ALSO WATCH THE TUTORIAL LIVE ON WAPBAZE YOUTUBE.. WATCH IT HERE NOW NOW FOR COOL TUTORIAL
