Thu May 10 00:34:19 2012: NV backup has been rebuilt.
Thu May 10 00:34:19 2012: backup NV restored from Secondary bak.
Thu May 10 00:34:23 2012: MD5 open fail. (No MD5 file) : /data/radio/nv_data.bin.md5
Thu May 10 00:34:23 2012: NV restored.(GED)Your /factory still as wierd permissions. Most of the files are owned by root and are not readable by radio, which will cause problem. This is probably result of restore. You made nv_data.bin owned by radio, but without accompanying nv_data.bin.md5 system will just ignore it and probably give you generic IMEI, which is what we were seeing here when md5 files didn't match bin files.well, i noticed that /factory was totally messed up due my attempt to fix it. I retore and fix permssions to looks just like yours but for a strange reason i can't restore .nv_data.bak and .nv_data.bak.md5 through root explorer...
in any case, even with /factory without almost all files inside the issue was exactly the same and i was able to make radio works with the "battery remove" workaround...
edit: exactly same problem, but now with a generic imei! =o)
i'm gonna restore my backup when get in home...
# cd /factory
# chown radio.radio .*
