Solution

- Check for short on PP_LDO11
- Check PP_LDO11 is getting 1.8V (power on phone with dcps or battery)
- Reball U_EEP_RF (small ic, 4 pins only, but be VERY VERY CAREFUL!! This ic is VERY SENSITIVE, if this ic crack or break, you can use board for parts because no more imei!)
- Reball U_PMICRF
- Reball U_BB_RF

Let me know what happens bro!
