[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] mcdull:
Okay. I managed to test the ROM from OP and here is my findings.

1. This is not an Latest Qualcomm AOSP Factory MM6.0 ROM. It is a custom ROM modified based on the same Factory ROM. So it is a custom rom with some app / settings added.

2. This ROM may contact DATA partition. I tried to flash this ROM and it goes straight into the system in Simplified Chinese. And it doesn't have any Google option even I flashed gapps. So I guess it has some irrelevant data in there. I then wipe the data cache again and reflash gapps and works like a charm.

3. This ROM has firmware related files. It has the latest radio from MIUI MM and splashscreen, I am not sure if it has others.

4. This ROM has VoLTE option once your flashed it. But I cannot test as the MIUI MM Volte patch author said that it works on SIM1 only. And my only 4G sim card was in SIM. Anyway, the option is there by default without flashing any patch.

5. Both SIMs work okay and I can disable SIM now

6. No FC for 30 minutes

Below please find the translation to the original post (to my best knowledge)

关于6.0部分软件打不开闪退问题，如论坛内有人发的6.0努比亚相机，需要在应用信息--权限 里打开所有权限，就可以使用了，

If you experience that some app were forced close or not started properly, such as the nubia camera for 6.0, please enable all permission in app setting for that app, and it should goes well.

刷机前需四清，否则会导致耗电等无法预知问题：

Please 4wipe before flashing, or you may face unknown issue such as battery drain.
