Fixing Certificate Errors On Symbian Mobile Phones

Symbian PhoneIf you use an Symbian S60 3rd edition based mobile phone (Nokia N-Series phones like N73, N95, N80, N91, N80 and E-Series phones use Symbian S60v3 as OS) you must have encountered the very common certificate errors like 'Certificate Expired' or 'Certificate Error. Contact Application Supplier' while installing themes or softwares on your phone.

Nokia Certificate Error

The errors are caused because of the security measures introduced into the new version of Symbian Series 60 mobile operating system disallowing installation of old applications and invalid certificates, however bypassing this security feature and fixing these certificate errors to install themes and softwares is very easy, simply follow the instructions below:

  1. Open you mobile main Menu.
  2. Navigate to Settings -> General -> Date and time
  3. Now change the year back one year.
  4. Fix Certificate Error
  5. Now install the application.
  6. Don't forget to change date back to original.

If the above does not solve the problem goto Application Manager > Options > Settings and set "Online Certificate check" = Off and Software Installation = All.

UPDATE: If you own an older phone you might receive the following error:

"Installation security error. Unable to install"

To solve this error and install application/Theme navigate to Tools -> Options -> Setting -> Software Installation and change setting to On.

Hi! Those steps used to work on my Nokia E71. Unfortunately I recently had some problems with my phone and had Nokia reformat it and upgrade the OS. After that, I can only install a few hacks. On some programs, I continue to get the same certificate error message. Can you recommend anything else?

Please help.

nokia e63 user...got probs with installing some symbian application like certificate error. can i have someone who has an idea bout this probs..pls help me fix it...

I hv tried evrything. Even hacked my phone. Bt there r still some apps which dont instal. F u find it, my email is rashidwarrior99@hotmail.com

still having that problem in n91,N73......
the error is the same ,i have tried many time...but it didn't work.....plzzz,Find some solution men......

Its all crap... just wasting your time... coz I have observed it works on some, on some it does not and once posted then NO one even seems to bother answering back to people who are still facing the problems... every where I have visited I see some enthusiast who starts the thread with a temporary zest and then all you find at end is a bunch of helpless people with their different mobile models asking the same crappy question and no one is then even bothered to sort it for them. Its a waste of time guys.....for me... even if I have install all and online check for certificates off.... it still gives the same f*@c*!^g error... when the Nokia N73 should not even bother checking for certificate. As the add says... Nokia has no brains....every model they have something or other lacking or missing. Better go for some chinese remakes... at least they use their brains.

thanz a lot. but i m not sure why this trick isnt workiing for some software. although its workiing many times. thanx again

its not working on all sets. like mine one, E90.
But why not all symbian applications are self signed?
its not a big deal as i researched. Anyways still lookin for a workaround for E90.

i can't install softwares with a file extension name of .sis. i'm using a nokia 6680 model what would i do???

I tried both ways. but it is still giving error on my nokia n97. anyboby could solve this problem for me. emeil me the solution on my mail address which is sajmon4u@yahoo.com

Thanks Heaps. Works Perfectly, great of you to put this here. THANKZZZ :]

yaar dey dont knw anythng...the above mentioned procedure z used to fix certificate expired error nly n not odr errors

hey guyz! i think the options above is an option for those who have "expired certificate" problem, but in our case we have "certificate error". the option above doesnt solve that problem...

Cacamasi pe el de tel

i try this a lot of time but i am still receiving certificate error on my nokia n73 plz help me in this regard.

I Have Tried All Of Them,But Not 1 Seems To Work,,
WHY?
Reply Back

I hv done that......in my E66

First go to.....

MENU->SETTINGS->APPLICATIONS->APP. MANAGER->SOFTWARE INSTALLATION(CHANGE "SIGNED ONLY" TO "ALL") and ONLINE CERTIFICATE CHECK TO OFF MODE.......
(according to my E66,just try it in ur's)

Hope it will successfully works in ur's too...

enjoy........ :)))

THXXXXX it really helped me
THXXX

Thanks for such a valuable suggestion it really worked in my Nokia E62 thanks brother.

i've done it many times on my nokia e66 but it doesnt work whao shud i do...please help...i cant install games and application...what is the other method i could use....??????????

i tried following your steps in E66. but not solved... any further idea? ammhakeem@gmail.com. i would be much thankful if any one can help me to over come tis problem.ammhakeem@gmail.com

It works on my E65 Nokia mobile. However, two reasons: 1. old applicaion 2. invalid certificate

If I want to get the certificate valid, what should I do?

first of all, the stupid "signed" system that all but freezes out small developers cause its expensive!

Then, even if you hack with Hello X, you still get expired certificate bullshit!

And regrettably, your method didn't fix mine, all I wanted to install was ZX Reader :P

Nokia is hard on the heels of Steve Jobs in control freakishness, but without the polish.

I will not buy either in the future. Nokia is dreaming if they think they can succeed by duplicating Apple's walled garden...err ghetto approach.

Android is going to smoke S60 and Maemo, even if Maemo turns out super polished and is as smooth as Apple's iOS.

Everybody I talk to is just sick of being controlled and foiled by corporate clowns at every step of the way, on devices they paid for with their money.

hey i still got certificate error in my nokia n73.......plx help me......reply on my email id arsalanalibaig@hotmail.com

Stil not working in my E71 phone....
please help me to solve it...

i hate having nokia s60v3 unknown certificates problem..pls help me am desperate for installing my application..it took me a lot of money and effort just for finding some solutions i need some help regarding that error..here's my email mossim0_11@yahoo.com

Please go to Menu>Tools>settings>date and Time> change the time 1 year back.

This will solve the issue. So you can now start updating the software of your phone.

i have nokia 5230. i have tried both changing dates and application manager way but still not working. once i clicked the icon and and it allow me to install, but after installation shown complete, the phone stated that "certificate errror and contact application supplier". the ovi suite from the pc showed that "installation failed. due to an unknown error installation failed. Error code:2152775105". it happened to all type of other application i have download. can you guy please help me out here?

Thank you :)

"Software Installation = All"

u know its work!! if says certificate error din still reduce the year until u'll find the exact year. don be afraid of reducing the year on ur cp u can back it on later after installing... if still the error is persist you can search the software so called SECMAN mobile edition install it on ur phone. after that, open the SECMAN press option & "turn flat. security Off" to ON & "INSTALL ROOT CERTIFICATE" only once.. hope this can help.. but remember always make ONLINE CERT=OFF & SOFT installation= ALL & reduce the year...

Hi all, if you get a certificate error, contact application vendor message, most likely none of the above would work. Because, symbbian insists that your application should be signed and you get the above error most likely because the app is not signed. You either need to get it signed by yourself (a painful process) or hunt for a singed version somewhere.

its an old solution.....only 1% of working chance.......for s60v5 phones its not well...

my nokia n73 rsa data securty certificate was expired plese help

i got nokia n96 and when i do install software's or themes it gives the expired certificate error .... both of the two options are done but no benefit.. still getting the same error.......... plz help me...

Certificate error. Contact the application supplier.

Hint: You may have tried installing unsigned application. Note that signing is mandatory S60 3rd Edition. You can use self-signed certificate or developer certificate from Symbian Signed to sign your application.

It worked!!! Thank you :)

After a long struggle, it installed AlternateReaderS94108.sisx on my nokia x6.

- restored the phone setting to factory settings
- switched off the phone
- removed & reinserted sim (so that it asks for date & time on restarting phone)
- entered the date to 1/8/2010 after restarting phone
- time 9:00 am (whatever it was default, didn't change it)
- then ran the installer from File manager

Hi it works for my Nokia 6120C

certificate error!! tried changing the date but still not working.. the phone i use is samsung monte. please help.. am trying to install whatsapp.jar

tq dear admin i got it & tx again for help i can installed.

HELLO!
I have a NOKIA N95 mobile phone with s60 3rd edition symbian operating system, I have an certificate error exactly in this way: "certificate error, contact the application supplier" when I try to install a dictionary software "asgatech unidic v2.00".
I have changed my phone date into past years and set "online certificate check = off" and "software installation = all" but it has exactly the same error when i try to install the dictionary again!
please help me and answer as fast as you can!
thanks.

Save all your files onto a memory card, I mean all files, downloaded applications and reformat phone ie, restore factory settings. Then reinstall your dictionaries etc. You may lose non-factory settings etc. Remove simm card and mem card before formatting, just in case.

thanks you are clever

Hi,
I've tried changing the date. I've also tried turning off Check for certificate in application manager. I've tried many things. I can't install a single software from websites like getjar, mobango etc. I've even tried from nokia ovi store but the same certificate error/out of date/invalid etc. keeps coming.

Need emergency help
Someone please if you can

Thanks & Regards
