Can't connect to active sync

[hanjin1]

I just downgraded to buttons rom so that I could unlock my phone I just got. It is a cingular phone but I use tmobile. The problem is that after it was finished and the phone restarted it couldn't connect to active sync. Now I can't use the lokiwiz because I can upload the file to my phone through active sync. what do I do now???

ok, i got the original cingular 2.25 rom and updated my 8125 back to its original state. when I do this the phone will connect with active sync. so i decided to downgrade using the button rom again and try to unlock my phone all over again. I can get through the button rom downgrade but when my phone restarts and goes through all the setup configuration, activesync will tell me it can not connect to my device. so now I am stuck at the same place i was again. I can't start lokiwiz because activesync will say that there is no device. what am i doing wrong? also when i downgraded the ipl sais 1.01 but the spl was still 2.25. is there a different rom i can use?
