From OP:
If at this point you wish to change frequencies open smanager app. Got it
Press green arrow at top right until you see / then go to system/ etc/init.d open it. Got it
You will see a file named 90modules open it as script/ executable. Confused, Mine either allows me to select ls script OR Executable , although I've tried both methods.
Select edit at the top. Open directly no copying! Yep, Always open directly, I've never chosen that "copying" in the prompt.
Use sm editor to open it if it asks. Yep
Edit the frequencies to your liking. Yep, change as described in last line 1325 to 1200 - making sure to add no spaces or anything
Press the back arrow on phone. Yep
Select save changes. When I do this it comes up "unable to save"
If it warns you about bricking device select brick. Never get to this ???
Exit app and reboot.
Remember to change profile if you use setcpu.
