First I would like to thank everyone for all the good input. I am hoping someone can answer my question. I have 4.1U softmodded and using Custom IOS38 Rev14. According to DOPIOS all of my IOS files are current. When I run multicios installer to install IOS37 with IOS37 rev7 dip as IOS 232 it downloads 15 files then gives a -1017 error and returns to HBC. I have tried several times with the same result. I have even tried installing IOS37 as IOS248, only to get the same error. Any help would be greatly appreciated.
