I live in the Philippines, I feel that flashing my unit to U1 locked me to US bands. I'm currently not receiving 5G signals on the phone. What I have is the 12/128 Snapdragon variant and my network here supports n78 (3500) 5G bands. Few questions below for clarification.
1. Will sm-g998u1 firmware lock me to US bands? As mentioned I'm not receiving 5G signals here in the Philippines.
2. Will flashing sm-g998w fix my issue with 5g signal?
Any help is appreciated. Thanks
