So I recently tried to update my wii to rev 19 from rev 14 of cios38. It installed fine on ios249. However at that point I could no longer install wad files using wad manager 1.5. I was using wad manager 1.4 previously. I kept getting a ret = -1029 error. This did not happen before. So I followed the tutorial at Installing Waninkoko's IOS249 for use with USB Loader to reinstall rev 19 to ios250. I am still having the same problem. So what can I do?
