T23G custom logo

[apant]

Hello.

I want to add a custom logo to my T23G phones but when i try to upload the .dob file I get the error "Upload failed! The size is too big!".

The size of the .dob file is 5k and it is 132x64 pixels. I also tried a smaller one but I got the same error message.

All tutorials I read are about T22,T26,T28,T32 and T38. T23 is not mentioned anywhere but the option for a custom logo exists on the latest firmware. Is it a fake option or I should do something else to work?

Thank you.
