[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] rubensa:
Thank you for the apk, but that's not the problem. I got the apk for 0201 version but the problem is that you need "extra" support for the FM internal chip communication in the "core" system (the apk doesn't interact directly with the hardware, it uses extra libraries and functions that, I think, are missing in 0218 build and seems not working including those from 0201 version).

SOLVED!

Required: Root

Navigate with a root explorer to your build.prop file located at /system/build.prop

Add the following line to the file:

Code:

persist.debug.wfd.enable=1

Save your build.prop file and reboot.

You should now see Settings > Display & Lights > Cast > Menu > Enable Wireless Display

Any clues on how did they solve the speaker crackling problem so I can try and fix it on other ROMs?

I have this problem on MIUI Global ROM 8.1.2 and Resurrection Remix (currently my daily ROM). Usually the crackling happens when the cell phone signal is weak (inside subway stations) and changing from 4g to 3g.

I just installed this Lineage ROM using Dual Boot Patcher to test it and apparently the crackling sound really disappeared (tried to reproduce manually changing from 4g/3g but couldn't hear the crackling)... I will know for sure when I go back home by subway today. :)

UPDATE: Same crackling problem occurred when I was inside the subway station. Problem was not fixed... :(
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] Lus7:
Can someone confirm this? This is my first time installing a ROM on a Mi phone. The first step is to unlock the bootloader, in order to do so - I must submit a form online explaining why I want to and it takes a few days for them to respond?

Does the reason matter? Will they accept any reason?

If I try to flash anything without Xaomi's authorisation, my phone will be bricked?
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] recharged20:
Unfortunately yes. Or you can do the unofficial one, though i have yet to try it.

not sure about this. I think if you say you'd have fried chicken to go, your request will be ignored. But of course they should accept any relevant reason that would merit approval, like wanting to have twrp/custom rom/xposed etc.

You can still flash other official mi rom via miflash but not custom rom - different boot.img, but for most quallcomm devices, unless it is a hardware problem, it is generally fixable - via reflashing through qhusbbulkloader driver i think.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] dels07:
Check picture attached for fix in crackling sound
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] BJumperBR:
I've tried that but didn't work...

Actually, my problem is happening while listening to music using earphones. Crackling sound everytime the cell phone signal is weak (inside elevators/subway trains). My guess is that it occurs when the cell phone is scanning for 3g signal. Hardware problem, maybe?

Well, it sounds like they will make a forum for this phone once there are enough threads about it. That should happen after kernel is released and development picks up. Currently, most users aren't helping the situation much by not making new threads for separate roms.

Yup. But kernels will be released probably within 6 months since première, like it was with other xiaomi devices...

This is my first time flashing so I have some questions:

Does the lack of official kernal sources mean it's not worth installing this ROM until they are released? Truthfully, I can't see myself using MIUI for another 6 moths :eek:

I am downloading "lineage-13.0-20170218-UNOFFICIAL-markw.zip" -> is that the right file?

Yes, encrypted with a PIN. It has not changed since 0102 and I always can flash the old version to get it working again. Some fingerprint drivers/configs had to have changed

[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] -droidberg-:
Same story here, with device encrypted fingerprint won't work, i tried with all available versions. To get fingerprint to work again you need to format data (lose data and remove encryption) and avoid encrypting device in the first boot. I think it is bug.
