DevcertList update
Paul.Todd | 06 January, 2009 13:54

DevcertList has been updated to version 1.2

I have seen a number of people getting "Constrained by certificate" errors and say they are absolutly sure they transcribed the IMEI correctly. To fix this I have updated DevCertList to check for IMEI's that are invalid and also IMEI's that have the wrong length.

The 3GPP specification outlines the checksum digit calculation to make sure the IMEI is valid.

This was a result of this thread over at the Symbian board..

Thanks that's a great tool.

I always have my last IMEI in list formed by two concatenated IMEI but my cer is working

Strange IMEI

Can you email me the devcert to test, it should have flagged an error as the length is wrong.

A consistent error should be called feature :)

It seems that Samsung devices have 17 digits IMEIs (IMEISV ?)

Reverse Way (SIS->IMEI)

You can use the SDK tool signsis to display the IMEIs from a signed sis:

%EPOCROOT%\tools\signsis -op SisFileToDisplay.sisx

In the X509v3 extensions are the IMEI numbers.
