Hello, I have some questions.
-Will I be able to flash with 12.5.4Mi?
-Will updates come through the update points in the firmware?
-Does nfc work?
-Will screen recording be fixed?

---

Should I have specific firmware version to flash it?

---

if anyone wants to know
For VOLTE use firmware 12.5.1

Greetings, this is the first ever rom i have flashed in my merlin, and so far so good! it works well, does what it is intended to. Almost everything is expected to work as the description suggests. Although i have gotten a few drawbacks, such as the camera seems to have degraded unlike the stock rom, and there is a bug in the phone caller in which it force stops out of nowhere whenever you access it. But it functions when someone is calling you. There is also this bug where com.mediatek.ims forcefully stops. It doesn't seem to affect the system entirely but i do think that it is somehow related to stock phone caller. So far, it is one of the best roms that i have flashed even tho its just the first time. 9/10 overall

SIR I FLASHED THE PIXELPLUSUI 4.6 BUT STILL HAS THE SAME BUG AS THE PREVIOUS ONE EVERY TIME THE SCREEN TURNS ON IT WILL FREEZE AND RESTART SOMETIMES WHEN I TYPE MY PIN PASSWORD IT FREEZES ALSO IS THERE ANY FIX FOR THIS SIR

---

1080p60fps and 720p60fps videos on YouTube and/or other Youtube clients like Vanced etc. lags. Also, sometimes when I switch to Light mode from Dark mode, Pixel launcher crashes.

---

How do i flash that one if i was on PPUI 11? Do i just clear the stuff and then flash this ROM? Or is there anything special for doing it?

simply go to recovery factory reset, wipe cache, dalvik, system, vendor partitions and then flash the rom/ you can sideload it too via adb. Let me know if you face any errors

---

Yeah, worked flawlessly. Sweet.
Good to know i didn't need any advanced instructions to flash it, working like a charm!
EDIT: Can confirm im having the bug on the phone sleep. How to fix it?

---

Can confirm that watching a video on 720p or 1080p on Youtube is EXTREMELY laggy, like 10fps or something, please check it out and see what's causing it, thanks

I just updated to 4.7 from 4.6 and I can confirm that there is a significant performance boost! The menus and overall System UI is smoother; Subway Surfers does not lag every time you make a move; and YouTube no longer lags when trying to display videos that are 720p60/1080p60 (Even 1440p60 is working mostly smoothly)!
I'd recommend everyone to try this build out, it'll help with many of the problems you're having. Update does not require you to lose your existing files/settings, although I noticed that I couldn't update from v4.6 using the built in OTA and so I needed to flash it on my own using adb sideload

---

Just installed v4.7, been using it for a few hours and everything seems to be working. There is a slight lag in general system navigation but is mostly smooth running. Hopefully the next update makes it more responsive.

---

Update : I flashed this firmware through ADB sideload and now lags have disappeared, full OS runs super smooth. No complaints.
