help with PAP authentication

[Guest :HELLO_GOODBYE]

Oke i got this problem with my GT-7610.

ive installed the rom from Daskalos Sense 2.5.2016 Build 23668 v1.2 and it works great everything runs smooth as silk for me .. until now :D

i know where the problem itself is but i just dont know how to fix it ..

i need to change from PAP to CHAP.

but in this rom there isnt any way of changing these settings.

i hoped somebody here could give me a clue on how to do this or explain it to me.

I thank you all :P
