how to downgrade from ICS to GB?

[The_Preacher181]

hi everyone,

i upgraded from GB to ICS bout more than a week ago. eveything was ok. and i was loving ICS. but oneday suddenly my internet stopped working. there was no data data traffic. reinstalled ICS by pc companion, then by SUS then by factory reset. still the problem didn't get fixed.

so i'm thinking to downgrade to GB from ICS. can anyone tell me how is it possible? i'd be thankful if step by step instructions r given.  looking forward. and please some1 save me from this trouble.

regards

you should check your APN settings

settings > more > mobile networks > menu > add new > enter the data > menu > save

that's odd, how about repairing your phone with SUS then try again, also if you can try a new SIM card
