Is it useful to use a custom kernel on a MIUI ROM ? - Mi 3 Q&A, Help & Troubleshooting

Hi, due to multiple problems on Lollipop ROMs on MI3, I finally came back to the latest sMIUI ROM.
I know that the new Kernels can be applied to KitKat ROMs, but is there benefits for it? I mean, will it bring back the 5.x problems like HDR not working, etc?
And more technically, how can those Kernels are finally able to work on both 4.4 and 5.1 now, and not from the beginning?
Thank you in advance.

HDR is now working in custom Roms

Ah, good news! But HDR isn't the reason I left Lollipop, I kept having network and touchscreen problems :
- Impossible to send or receive MMS (no matter what APN or setting I use)
- Impossible to access to some services or update applications data over 3G (couldn't download a file on Google Drive, couldn't see a video on YouTube, couldn'd refresh posts on 9gag...)
- And sometimes, the touchscreen was buggy, it didn't responded well, so I had to lock-unlock the phone a few times before it start working properly
So for now I'll stay on MIUI KitKat, but I would like to tweak it so it will be at its best

Sorry to hijack the thread, but can someone recommend a good LP kernel that is worth flashing with the new MIUI7 and/or the Xiaomi.eu MIUI rom?

First thing is you cannot use a lp kernel in kitkat rom such as miui and smiui. But you can use custom kernels like GOD'S KERNEL, MOSHI etc. Search the forum.

My power button is loose and I use zeurionx, I think it's compatible with miui and aosp. It has wake gestures dt2w and s2w.

[Fix/Patch] Flashable Call Audio Fix for T/W8 devices on Int' ROMS (920 F/I/K)

Flashable fix for call audio that is kernel independent and will patch International based ROMS to work on your T/W8 variant.
You still need a kernel that is T/W8 compatible flashed for this patch to work.
Code:
You can get it [URL="https://www.androidfilehost.com/?fid=23991606952614440"][B]Here[/B][/URL] for 5.0.2
And you can get it [URL="https://www.androidfilehost.com/?fid=24052804347831878"]Here[/URL] for 5.1.1
Updated 5.1.1 package to BOI6
This patch can also be implemented by ROM builders who wish to build a F based rom for their T or W8 devices Just remember to give credit where it is due. This was a bigger pain in the butt to track down then it appears.
Let me know if you find any issues that may be relative to the fix. Tested and working by my self and a few others.
This patch can also be implemented by ROM builders who wish to build a F based rom for their T or W8 devices. In that regard it *should* also work on Edge variants as well.
Rom builders: you can also use this to build a truly universal ROM one flash to cover it all.
Download my kernel and examine its structure. specificallt look at the scripts that probe device variant and then copy the required files and kernel. You can adapt this to work the other way . But always run it *at the end* of the installation script so anything it patches does not get overwritten by your usual installer code

I'll have to patch up the kernel for that we should also be able to support it.

Gav, the A is a T/W8 variant but has a locked bootloader. don't waste your time they cannot flash kernels. But thy can flash roms and my fix will work since they will be on a stock kernel. well *work* hopefully lol
Edit: Never mind Google+ was keeping the device from sleeping. Please disregard.
NJGSII said:
Ive noticed that flashing either the full kernel with the fix or just the fix itself ontop of ktoonez's kernel, my device doesnt enter deep sleep. I did a test where i just reflashed ktoonez's kernel without the fix and sure enough the device enters deep sleep again.

True. Found out what the problem was and it had nothing to do with this. You guys are good!
I've tried this on the G925T (The TMo S6 Edge), but it didn't seem to work with ktoonz kernel. Not complaining, just letting you know. Thanks for your hard work and assistance (both of you).
*Edit*
Installed Simpl Kernel with this mod and it worked. I'm using XtreStoLite ROM, but didn't work with ktoonz at all (with the fix). Flashing Simpl with with the fix worked just fine. Still need to get used to the Intl ROM.
My apologies beforehand, would you mind clarifying what this patch allows us to do. Can we patch Roms from other providers, I'm just a little confused.

T-Mobile WiFi calling optimized ROM?

I have been looking for an optimized T-Mobile WiFi calling ROM, looks like no body cares about this feature because it is only few ROMS using this feature. I am using the stock rooted but it is bad with the battery and I am used to the battery use in Chrome ROM. Could someone point me to a good rom with the best features and battery with a WiFi calling enabled? Thank you.

its only available in stock(or stock based ROMs?). its added in by tmobile, and not open sourced(yet?). and the majority of ROMs are based on aosp, and the code wasnt put into aosp(yet?). so if you want WiFi calling, you'd have to use stock, or m.
I was about to post the same question... any answers?

The wifi calling bits aren't part of AOSP, a few people have tried to "reverse engineer" it, but with limited success from what I understand. I think part of the problem is finding a developer that has T-Mobile. Being that some of our devs are from all around the world, and even the ones in the US are likely not going to have T-Mobile. This makes their testing slower and/or harder.
I think there are a few that are still working on it, but I don't think it is a major focus of anyone. I know a couple have sorta given up on it.
tl;dr - No custom AOSP (or variations of it) currently have it that I know of, stock ROMs are the only ones (plural because this includes M dev preview) that offer the functionality.

No. Just about any ROM that has been updated in the past month or so should have it built in. The OP of every ROM should state if it includes it, and if it doesn't then there is a good chance it doesn't.
Just as a note, kernels also matter for getting wifi calling to work as well, if you decide to flash a different than what is included with the ROM.

PureNexus is optimized for Project Fi now, and T-Mobile calling is working fine. Been my daily driver since the first release July 5... I kind of miss crack flashing, but it's stable and has lots of great extras! Plus the Dev and community are super helpful!

You'll find WiFi calling in Dirty Unicorns, and in PureNexus as has been already noted, plus Chroma, I believe Minimal OS, AOSiP, as well as most stock based custom roms (include Gapps)...from what I can tell, no Cyanogenmod based rom has it...I'm sure there are others.
Best to flash and try it before fully setting up the rom itself. Here is why...if the feature is important to you, it can take a bit of tweaking to make sure it works...for starters, if going the AOSP route, you'll need a WiFi calling kernel (Lean kernel version 2.10.6 works perfectly), a proper T-Mobile WiFi calling modem, and those include 14R, 16R and 17R...and sometimes you'll need to toggle WiFi calling on and off, reboot, and you also may need to dive into developer options and flip the switch aggressive WiFi to cellular handover.
Good luck!

There is no "best ROM". These questions are generally frowned upon as well. What works best for me, may not work at all for you. As @simms22 said previously, there are a wide variety to choose from. I suggest reading the OP of any ROM you choose, and seeing if it has the features you need, then flash that ROM and try it for yourself. Also, read the users comments within the ROM thread to see what their experiences are. The only way to find the best ROM for you, is to try several and decide for yourself.
Good luck!

Stock rooted hard coded without Xposed and GravityBox. LMAO
My personal two favorites are Euphoria OS and Benzo Rom (which is based off Euphoria) mainly because it contains Cyanogenmod features while keeping an AOSP base. Also I love how Viper4Android is built in to Benzo Rom. However it comes down to you on what you want to install.
Nice ROM to try
I have installed a Rom called "pure nexus " with modular gapps who have nice preinstalled support of layers and is very stable fast and battery saving and i have personalized with someone layers to remenber playstation.
Euphoria I just try but is very instable, app crash and home crash..
I tryed chroma but isn't a nice ROM for me because have low costumization but is good and fast.. All ROM I tryed have a support for not encrypted I hate it
Gravity and framework i have installed on my all phone but i don't like the release alpha for LP because when i need to install a next release for ROM with bug fix framework need to re installation and all app in the ROM need to optimized..

LOST in a sea of roms

Hi there.
I been spending several hours reading user's opinions about several roms for the xsp.
I saw plenty of unofficial roms based on cyanogenmod official roms. And the question that pops into my mind it's.
Why so many mods? People doesn't like the official releases?
Also I been reading that 5.1 roms are laggy, and in a custom rom i'm looking for stability and performance.
Maybe I should go for and official cyanogenmod 11 rom?
Maybe for a stock based rom?
What do you think?
Hello.
Yes, there is a lot of rom for SP. But just a few work as it supposed to.
Lollipop it is in his nightly stage, though is very stable and the most recent apps, you will be able to use.
There is too a recent patch for security, we should take in consideration, Im using myself as a daily driver without problems, nevertheless still have some minor bugs, but nothing that cant make you wish to throw your SP on wall
If you want to test and see how looks like, I would recommend Sabermod Unofficial Or CM 12.1 Official Nightly
cm12.1+ addons imo cuz it's my second full month on it and it never failed me ....no problems for me and great performance

battery is good too yep
Go for CyanogenMod 12.1 nightlies with addons...Its Best for lollipop based ROMs.
You can try unofficial CM13 also if you can use the phone without camera. Battery life and performance of CM13 is far better than cm 12.1.
To be honest, is a matter of usage and preference. For me it was working fine but my phone got way too hot for my taste, but the deal breaker was that no matter what lolipop ROM I used facebook HD playback was choppy as hell. I know that it sounds silly but that's something that I need. None of these issues exist on stock, of course (C5306 - 1.205)
I think the Sabermod unofficial takes the lead on cm12.1 ... Great battery and butter smooth. I think it' s the for performance and battery !
I use official CM11 slimmed by me, without gapps, disabled LogCat, little modified build.prop + WilliamsPLUS and I'm really happy ; p
which 5.1 rom has fewer lag and more batterylife?
@beodo
A sea of roms but many of them are discontinued or not updated, so first check that one.
As fellow members said CyanogenMod 12.1 Unofficial SaberMod with add ons is the best right now for me as well, very fast, really fluid,stable and good battery life, in is some parts is even better than the latest official stock rom.
I m using this rom for over a month and i love it.
If you need even better battery life you could use Helium kernel (just dirty flash at recovery) and enable conservative governor, if you would like to take it further you can also install xposed framework which unlocks you much more features like power saving better experience, extra customization and more.
All of the above are continuously updated and supported by our great developers too :good:

You gain google dialer, google contacts, google assistant, xposed, full backups, identifying wakelocks, custom kernels and systemwide ad-blocking to name a few big things you can do just on rooted oxygenOS.
Just root it, the sooner, the better.
If you decide to do it later on, you'll have to backup everything since unlocking the bootloader implies wiping the data.
