Sure, place all 3 in /system/etc and overwrite when asked. Fully restart the phone after replacing the files (preferably a shutdown and fresh boot).
If it still isn't locking, get GPS Test from the play store and clear and update AGPS. Should instantly lock then.
Once again, I updated and clarified the instructions.
Thing is, only with baseband update the SIM card will work.
Here are my instructions, feel free to copy&paste them as you like:
1.) Download the latest baseband that matches your phone (duh):
for N9005: vidwhal: Recommended links are in the above text for n9005\hlte
for N900W8: https://www.androidfilehost.com/?fid=673368273298969743
for N900T: https://www.androidfilehost.com/?fid=673368273298969970
2.) Download a copy of Odin (3.12.x): http://dl.sammobile.com/Odin3-v3.12.7.zip
3.) Power down your phone completely, take out the battery for a few seconds
4.) Go into download mode by pressing Volume-Down + Home + Power simultaneously for several seconds
5.) Connect phone via USB cable until Odin says "Added"
6.) Click on "Options" and uncheck "Auto-Reboot", then load your Baseband file (_Baseband_Firmware.tar .md5) into the "AP" slot
8.) Wait for success and green light
9.) Unplug USB cable, reboot phone by holding down Power button
You are now clear to install the latest official LineageOS\RR for your Note 3!
