Hi,
According your inventions, we have prepared T-CHL7DEUC 2005 firmware with custom GMT settings like:

Code: Select all

Austria       GMT+1
Czech         GMT+2
France        GMT+3
Germany        GMT+4
Hunngary     GMT+5
Ireland     GMT+6
Italy       GMT+7
Netherlands   GMT+8
Slovakia      GMT+9
Spain         GMT+10
Switzerland   GMT+11
United Kingdom GMT+0
Other        GMT+3

Works like a charm! It is enough to change Channel-Country-0000 and we get time+EPG working properly.

Now how about patcher? Might we need to patch more countries at once to be sure we get patch working, because i got problems with Others, but it worked well on Slovakia (all other countries from list have been checked and are ok)

p.s. vanek, you should register on ixbt.com ;)

yes, Erdem, yes!

Here is no Turkey in the TV list. Countries above are patched as is: next country in the list gets +1 GMT :lol:
But i`m sure you`ll find the best way to organize the patch.

I wanted to implement this hack to Firmware patcher but don't understand the structure. My IDA doesn't show thing like "TCCountrySpecSingle" structure.
Am I doing something wrong? Might be some settings missed on IDA... Help me for helping you :D

Anyway, I will try to add this GMT patch option SamyGO firmware patcher if it works as intended.

A bit from research: firmware T-CHL7DEUC 2004.1 (exeDSP binary):

Code: Select all

012232C8: FB FC
012232C9: B4 FF
012232CA: FC FF
First two are original - secod two - to change with.
After patching we have GMT selection menu (plug&play - language - GMT - language - channel search)
Region in SM - SP it was chosen for tests. We have here Spain and Canar Islands:

Here are just first findings, work is going on further. Thanks to Rvs2 from ixbt.com :)

It was not disscused on ixbt forum. Just private findings over skype ;)
Here are images in
/mtd_appdata/Images_960x540/SingleMenuTimeZoneAU/
/mtd_appdata/Images_960x540/SingleMenuTimeZoneES/
for those menu, and no other countries are here. I think it is for test purposes only...
Patch codes for spain you see in my post above.

Hi vaniok!
There is a desire to solve a TimeZone problem, there are operating time it is necessary to test them!

Whether it is possible at inheritance from base class, to increase an amount of properties in child, at an overload of events?
