S7 刷馬越菲泰版 6.0.1 即能 4G+3G ？

S7 S7E E8890 目前所知是一定要升級到 7.0 才能 4G+3G 雙卡雙待，S7E 的 S820版(香港機即是) 則能 6.0.1 就可 4G+3G。

鑒於台版 S7 S7E 7.0 似乎仍問題多多，故才想找 6.0.1 即能 4G+3G 的方法。

好不容易搜到一線曙光，似乎 馬越菲 及 泰國 版的 S7 G930FD 6.0.1 官方韌體即能 4G+3G 雙卡雙待，而且三星好像刷國外版官方韌體並不會有去無回，無法回台；刷各國三星官方韌體只要不Root，不觸發熔斷KNOX 0x0，就不會影響保固及一些三星官方APP如My Knox虛擬安全空間的使用。

故想請教各位前輩，以台版 S7 G930FD 刷馬越菲泰版 6.0.1 官方韌體(含CSC)

1. 真的就有 4G+3G 雙卡雙待嗎？

2. 會有什麼明顯的問題及後遺症嗎？


感謝大家在先。

For Samsung Galaxy S7 Duos(SM-G930FD) users:

I can confirm that dual sim cards are working on 4g + 3g network mode on the following firmware:
PDA G930FXXU1CPK5 with CSC G930FOLB1CPK5

This firmware hasn't been uploaded on Sammobile.com yet. So, firstly update to the previous version (G930FXXU1CPJ2+G930FOLB1CPJ2), and then use OTA or SmartSwitch program to update to the latest one.

If your S7 Duos is not able to turn the 2nd sim to 3g mode and only working in 4g+2g mode, it can be fixed by updating the firmware to different country. As far as I tested, the recent G930FD firmware for Thailand works perfectly without any issue on 4g+3g dual mode.

If you boot into download mode, the phone will even display G930F as its model number. You can run F firmware on an FD without issue. As for the dual SIM working, I haven't tested it, but I did read that SIM1 has full connectivity, while SIM2 is limited to 2G/3G. You can't have two 4G SIMcards active at the same time.
