[Xiaomi Redmi Note 5 Pro ROMs, Kernels, Recoveries,] Desmanto:
I move from RR pIe 20190829 to this Havoc 3.0 20200101.

- Do a complete backup, TWRP, migrate and copy internal storage important files

- Wipe /data, /system and /vendor (clean)

- Flash latest firmware 11.0.3.0

- Flash the ROM Havoc 3.0

- Flash opengapps nano beta 20191209

- Flash magisk 20.2

- Flash migrate zip, all parts (so i can restore later)

After flashing :

- First reboot, havoc logo appear, then stuck at MI logo for so long. After 5 minutes I force restart, it boots to havoc logo, 1,5 minutes and entering setup now.

- Do all the setup, disable play protect (as it interfere with migrate) restore apps from migrate and customize stuff

- Most app are restored properly, call, contact, sms, calendar are back. Wifi and bluetooth need to be reconfigured though

- Most app permission are restored, but some special permission still needed to be enabled manually (accessibility, draw over other app, usage access, body activity)

- A lot of old apps require to prompt for the permission again.

- WearOS link to my ticwatch was broken and need to be re-pair. Fortunately found the way to reconnect without reset, save me sometime. I was shocked at first, that the data were lost. Somehow it is back after proper sync, granting permission and reboot.

Quick review after 24 hours :

- VoLTE is working find, both sim card OK

- Charging is slow when display is on (less than 1000 mA). But sometimes it is decent, 1400 ish. My widget show about 1200-1400 mA when screen off.

- Speed is noticeably faster. Don't know if this is because the firmware, kernel, just clean wipe, or the ROM itself. My typical Control UI flow usually slow down during animation. But now in havoc, I have to set a higher delay so it doesn't execute too fast. All animation is set to 0.5x as in RR pie. This is the thing that me stay now.

- No privacy guard, I miss this feature. But android 10 permission feature seems to be working almost close to it already. So I can deal with it.

- Network traffic only show 1 value and sometimes disappear. It happens also in RR, don't know why.

- Turns out no smartbar in the navbar :( I really mist this. Try custom navigation and it is not compatible, testing the compatibility always result in back to lock screen. Trying setting value manually end up freeze every unlock. Fortunately I have adb connected and reset the value, so I don't need to reset. I now have to work with the GMD gesture to replace those smartbar I needed the most

- Double tap awake seems not working. Double tap works after enable and restart.

- Bluetooth headset is working fine. Cable earphone will be tested tomorrow.

- Android 10 location feature now can limit to when the app is open. I stuck at this figuring out why some of my flow doesn't work when Automagic is not foreground. Turn out I have to set it to "allow all the time". Now location based flow working fine again.

- Location seems to need to be always on for most wifi/bluetooth related flows. If I turn it off, most of my flow not working properly

- There is no option to disable wifi/mobile data usage in the app info. Now only background data can be toggled. It seems to behave the same.

- GCam 7.2 series not working. GCam 6.1 v6 marlin-ku is working, but front cam is black. It seems require the patch. But I haven't try it yet.

- Overall I find it has less customization from RR. But the thing I miss the most is the smartbar. Is there any possibility to add this in the feature? Or at least make the custom navigation app compatible.

Thank you for the ROM.

UPDATE :

- Double tap work after restart

- GCam 6.1 marlinku is working after flashing RN5 patch nhappyman for custom 9.0 fw 9.0. But the front cam still randomly black. 4K not working, 1/8x and 60 fps not working.

- I actually find the sound output is better than RR. But this maybe subjective

- Earphone with mic is working fine. Earphone without mic produce no sound at all, even though connected.
