Constrained by the certificate
Posted: 24-Dec-2008 17:54

sign , certificate , problem

Hi,
I have 2 IMEI's in a certificate. I am able to install it E71 without any issues. On N95 I can't get it installed. It always says constrained by the certificate.

I verified all the common issues posted here, like Verifying for Symbian A certificate.

PKG File.

;Languages
&EN

;Header
#{"MMIFilter"},(0x200210E5),1,0,0

;Localised Vendor name
%{"Openstream Technologies"}

;Unique Vendor name
:"Openstream"

;Dependency :: Supports s60 3rd edition fp1 and fp2
0x102032BE, *, *, *, {"S60 3rd Edition, FP1"}

; MMIS60Filter dll

"$(EPOCROOT)\Epoc32\data\z\resource\plugins\MMIFilter.rsc" -"!:\resource\plugins\MMIFilter.rsc"

Output from devcertlist.exe for certificate.

Correct

The second IMEI (392255019682925) is not valid. The final digit of an IMEI number is a check digit, and it shows that this IMEI is wrong.

I think you have mis-typed the second digit, it should be a 5 not a 9. If you make that change then the check digit will be correct. You'll need to get a new developer certificate with the correct IMEI.

Mike.

Hi Mike,

Where did you find the information about the check digit as its something I could easily add to DevCertList

Helpful

Hi Paul,

The 3GP site has the definitive specification of the IMEI in specs 22.016 and 23.003 http://www.3gpp.org/ftp/Specs/archive/23_series/23.003

IMEIs have 15 digits, the 15th being the check digit.

Samsung used 17 digits in some of their S60 phones. (In particular a device that was on the Nokia RDA for a while.) That is CTelephony::GetPhoneId returned a 17 digit string and developer certificates had to use all 17 digits. The first 15 digits were the IMEI, the 15th digit being the check digit. They had an extra 16th and 17th digit, this looked to be a cross between the IMEI and IMEISV. So beware making the dev cert list too prescriptive because this could cause issues with non-standard implementations.

The check sum is calculated as follows:
(Replace brackets around i and around 14 with square brackets.)

int checksum = 0;
for (int i = 0; i < 14; i++)
{
int v = (int)imei(i) - (int)'0';
if (v < 0 || v > 9) return false;
if (i % 2) v *= 2;
checksum += (v % 10) + (v / 10);
}
if (checksum % 10 == 0) checksum = 0;
else checksum = 10 - (checksum % 10);
int targetcs = (int)imei(14) - (int)'0';

return (targetcs == checksum);

Thanks a lot. The IMEI characters were so small, even after verifying 5 times and by 2 people still we got it wrong

That's why I am going to update devcert list in the next couple of weeks with some heuristic checks to ensure the IMEI's look okay.

Ideally, if you have a copy of the devcert that has the corrupt IMEI's in it I would like a copy to put into the test harness to ensure that these cases are catered for correctly.

Devcert list has been updated over at the Forum Nokia wiki

http://blogs.forum.nokia.com/blog/paul-todds-forum-nokia-blog/2009/01/06/devcertlist-update
and
http://wiki.forum.nokia.com/index.php/Listing_IMEIs_and_Capabilities_in_a_DevCert

This should now be up to version 1.2.

Please let me know of any bugs and ideally also include any devcert you are having problems with so I can reproduce it.

Great tool. Thanks Paul! Can we also include it on the developer.symbian.com/sstools page? Would you object?

That's cool,

The other tool we use quite a lot is AnalySIS as it shows all the data in the sis file correctly
