Solution – Certificate Not on Phone or SIM
error (Nokia s40)
Nokia
Sometimes while updating the phone or
when you’re just completely out of luck, your
Nokia phone may not install any new
applications because it has lost all its
certificates which are used to install signed
applications to the phone and allot them
proper permissions depending on how
much can they be trusted.
People keep asking me for help regarding
this same question again and again. So I’m
publishing a solution here to help anyone
who faces a No Valid Certificate or
Certificate not on phone or SIM error on
his Nokia S40 phone (even other phones
can get the certificates through this method.
Just give it a try.
Procedure to re-install Nokia s40
certificates
All you need to do is to open the certificates
in the phone’s default browser. Opera Mini
or Nokia Browser will NOT work. I’ve
uploaded the certificates onto the server
here, so it is just a few easy steps for you.
1. Compose a new SMS in your phone.
2. Write http:///NokiaCertificate as
the content.
3. Now either save this SMS as draft or
send it to your own number so that you
can access its content in the message
viewer.
4. In the message viewer, select the link
and open it (tap on it in case of touch
phones).
5. From the page that opens (http://resources.techmesto.com/
NokiaCertificates/), keep clicking on the
various certificates and Install them.
6. The certificates will be installed and
available for approving signed apps.
7. To confirm, you can Goto Settings>
Security> Authority Certificates
Alternative Way:
If you have access to entering the web
address in your default browser (web), you
can just skip the first 4 steps and instead
manually enter the address http://
resources.techmesto.com/NokiaCertificates/
in your browser’s Go To Address column
and install certificates from the page that
opens.
I hope this content is clear enough.and if still u cnt get it. Keep me posted.

Solution for Conflicting Apps error with
Nokia Browser in S40 phones
Some users are experiencing issues when
they updated the Nokia (Express) Browser
on their Asha or other s40 based phones.
The problem occurs because the update
doesn’t go up successfully. In most cases,
some of the files from the older version
remain there which causes the updated
version to show a ‘Conflicting Applications‘
error which makes it impossible to open
and browse using the default Nokia
Browser. The issue did reach the Nokia Devs
but because a very small number of users
are experiencing this, the resolution was
withheld except for some very new devices.
Solution to the Conflicting Apps error:
If you’re also experiencing this error, you’d
have noticed that even a full factory reset
doesn’t solves the problem. So, follow the
steps below to get rid of the error. It has
worked for many but it still isn’t sure that it
will definitely work for you. You can try
though:
1. Firstly backup the important data
present on your phone using the
Backup Utility (in settings) or backup on
your PC using Nokia Suite. If you don’t
backup, you will lose all your data such
as Text Messages, Contacts, Calendar;
etc.
2. Now you need to reset your phone to
factory settings. You need to choose
Full Restore. Please note again that this
will wipe all your data present in Phone
Memory, so do backup before you start.
You can first try by skipping this step
as it might work out without the need
for a factory reset.
3. Install Opera Mini browser (if Opera
Doesn’t work, use UC Browser) on your
phone. You can either install it using
the Nokia Store utility present on your
phone. Or otherwise, install it using
Nokia Suite on your PC.
4. Open Opera Mini on your phone and
browse to following link: http://
download.browser.ovi.com/
5. You’ll be able to re-download Nokia
Browser from that page and your
problem will be solved once it installs
properly.
6. That’s all. Enjoy super-fast browsing on
your Nokia phone again.

Nokia Lumia (Windows Phone)
While the Access Point settings for most of
the operators are pre-installed on the Lumia
phones, there can be situations when you
need to change the Access Point, be it
because you’re inserting a new SIM or the
pre-installed settings aren’t working for you.
Here’s a quick guide to help you set-up the
Internet Access Point.
Windows Phone devices, unlike the older
Nokia Symbian and S40 phones can’t be
configured automatically, so you need to
manually enter the Access Point settings and
then activate the Access Point.
Setting up Access Point on Nokia Lumia
Keep your Access Point details ready before
you start below. If you don’t have them
handy, call up your operator to ask for the
details such as – Access Point Name,
Username/Passwords, Proxy Port, Proxy
Address besides others.
1. From your start screen, swipe right to
reach the list of apps.
2. Tap on Settings and scroll down and
tap on Access Point.
3. To create a new Access Point, tap on
Add towards the left of the screen.
4. Now on the Settings page, enter the
details as provided by your operator.
Connection name – Can be anything
with which you can remember what is
the Access Point for. Access Point Name
– Specific to each operator and
sometimes different plans require
different APNs.
Username/Password – These are
usually left blank for most of the
operators.
Proxy Port and Address – Again
something that your operator will
provide (if needed).
5. If you want to set up MMS as well, you
can enter the details when you scroll
below. MMS configuration will be
provided by your operator.
6. When done adding the details, Tap on
the Tick towards the bottom middle of
your screen. If there’s no generic
mistake, the phone will save the APN.
7. Once done, you’ll reach back to the
Access Point screen. Just long tap on
the newly created Access Point to
Enable, Edit or Delete it.
Start browsing the internet and download
amazing new apps and daily new launchers
on the Windows Phone store. If you’re
facing any problem with this, or anything
else related to your windows phone.
