For all those, who have problems accessing provider-based services via WAP after updating firmware to a un-branded (newer) version:
the web-browser of your phone is identifying itself via a string, called ‘User-Agent’, looks like
SAMSUNG-SGH-F480/F480XEHJ1 SHP/VPP/R5 NetFront/3.4 Qtv5.3 SMM-MMS/1.2.0 profile/MIDP-2.0 configuration/CLDC-1.1
after updating to a newer, un-branded firmware, this string changes. Not only firmware-version, also branding-information changes. So, if your provider checks the branding of your phone, it may be that some special offers, like eg. Mobile-TV or account-based services, will not work.
Enter service-menu, go to ‘Internals’ -> ‘Protocol-Settings’ and enter ‘UAgent’.
Change first part of the string to the needed values. For example, a Vodafone-branded phone from Austria shows:
SAMSUNG-SGH-F480-Vodafone/F480AUHG2 SHP/VPP/R5 NetFront/3.4 Qtv5.3 SMM-MMS/1.2.0 profile/MIDP-2.0 configuration/CLDC-1.1
Don’t change the rest of the string! It is recommended to check the first part of the string before updating to a newer firmware. For this, enter the following URL directly in the WAP browser on your phone:
http://www.handysoft.info/headers.php
it shows the complete header information needed. After this change all services should work again!
If not, it may be useful to clear the browsers cache and reload the WAP page..
