So I've read the different posts in here about how to make the D100 work but i am still getting a No Service message on the D160 handset. I've got the IPO set as file server, no d100 files on the SD card, downgraded to 9.0.6, tried to upgrade firmware to 2_0.9.6 from 1_0.9.6 (it won't upgrade firmware). Everything I've read says it should be good to go. I am currently downloading 9.0.5 bin files to downgrade even further. What else am I missing? Thanks
