Building Rom from Source for Redmi Note 9/10X Merlin - Redmi Note 9 Guides, News, & Discussion

Hello guys, I was planning to build a rom from source so that we can start integrating different custom roms for our devices. I have a rig with good specs and a good internet connection too. What roms do you suggest to build?
I was kinda planning to build anything that's possible since our Device Tree and Vendor Blobs is now available. I think this is a good opportunity.
Kindly leave some suggestions, I'm just a newbie.

CrDroid, Pixel Experience and Ressurection Remix.

But, why custom?
I really prefer the original stock ROM and keep the system unchanged.
So I love magisk, because I can root without having to modify the system.
Together, Xposed, XprivacyLua, Adblocker and TitaniumBackup are all perfectly fine.

MIUI lag like crap and drains battery crazy, at least on my phone.

If an O.S. developed by many, many people who are paid to develop this, has lags,
why won't an O.S. developed by one or two people have lags too?
If your battery is discharging quickly, just track battery usage and see what's draining excessively.

hmmm I must have bought a fake Device with a cheap 3rd party battery and Dual core 2012 MTK processor, or the many, many people are hired mainly not to develop the OS, but hired for inserting pernament adware and bloatware in the Device so that they could earn extra money.

I kind of hate apple Locked crap. The system updates destroys the nice flagship, and if you do not update, they will greet you by not allowing you to install any app.
Samsung is nice for me, but if you hate Samsung, I have nothing to say.

I guess you've never used Custom roms.
Custom roms perform better than MIUI, No bloatware by default and they have a better UI.

The computer science of Xiaomi devs should be teached by their PE or Music teacher. Even DIY roms are better than MIUI.

That's the issue with Xiaomi, good hardware, poor software. They are able to provide cheap smartphones only due to earning money from ads in the softwares. Let's see development for Note 9 is going good now, almost every bug is fixed and device tree is stable, forums for note 9 should be filled with roms within time.

If you don't like MIUI, certainly you should not buy a Xiaomi phone.
I prefer systemless modifications.
If you have enough time for wasting, it is not my problem.

We aren't expressing what we like or what we don't, We're telling a man what to build. So please if you don't like custom roms, you may leave this thread.
Talking about "not trusted" , Custom roms are better in terms of privacy too and are trusted.
Saying a custom rom can't be trusted is one of the dumbest thing you could say on a tech platform with tons of custom roms threads.

There are thousands, if not millions, of people using custom roms on a Xiaomi phone and not a single one said their phones are hacked due to the custom rom. To say the least, Even MIUI is not close to being trusted as soon as you unlocked the bootloader.

Xiaomi builded the phone. So, I trust on Xiaomi O.S.
Anybody can build an O.S., so I prefer to keep with Xiaomi O.S.
If you prefer to use an O.S. builded by anybody that will never update it, well, it is your problem.
I prefer to keep with original stock rom.
It is my opinion.

Custom roms are regularly updated, they have maintainers for specific devices who update the rom regularly, with security patches. Please do not speak of something which you don't know of.
Any more replies to this will be ignored, Since you clearly don't know what you're talking about and this is going OFF-TOPIC.

Will there be any custom roms development for this phone??

Does anyone know if there are any custom roms being developed for this phone?. It's odd to see such a power house not be developing into something greater, it will be a shame to sell due to lack of development. P. S respect to all developers over the years for the great roms I have had the pleasure of using onany handsets
Doesn't seem like there will be, if there is audio may be a problem. Came from the Axon7 and the audio was trouble for the devs.

Custom ROMs Security

Hey everyone!
I want so bad to install viper4android on my brand new Pixel 2 xl but I have some security concerns...
How do you guys trust the devs? How do you know that your data is not being exfiltrated? Are the costume roms more secure?
I believe they're better in terms of privacy against companies, but are they against hackers?
How are the vulnerabilities handled? Do devs write secure code or just code that works? Do the new features get security patches?
Come on, please convince me installing a custom ROM!
Cheers and good christmas.

I can't convince you of anything my friend, nor will I try. I will just say this, one of the Devs for V4A and I have had some great conversations, he helped me get some specific ViPER features going, and I provided him with logs, and specific files he needed. I haven't had any issues with data loss or anything else. Also, my faith in the Devs on XDA is pretty solid, they're a bunch of talented, good, and helpful people, therefore, I trust them. And that's all I have to say about that (Forest Gump)

Sure, as long as you remove root, disable USB Debugging, and relock the bootloader. Then and only then will you be truly secure. Obviously, I have serious doubts regarding the claim that their security is higher than stock. Equal to stock perhaps, but not higher.

Totally agree with you mate, but by "privacy and security" I mean the phone will be soo yours and the Google guys can't force you with some updates to ruin the battery and slow the device like they did previously

Now that's odd as I have had absolutely no issues with battery drains or sluggishness running the stock ROM on this device. In fact, I stopped running custom ROMs because of how good the stock ROM is.
If you're encountering battery drains and sluggishness, look to the apps you install rather than blame Google.
hope you guys would be able to keep up a decent talk ... otherwise, I`ll be forced to close this thread and it`s not fair on the OP, he just wanted an opinion from more experienced users, thanks !
With all my respect, I won't close someone's thread just like that without OP's request, I've made my point and I hope it was clear, I still believe in love...
As long as you use common sense with what you do to your device, and you follow the lead of users around you (stay away from the stuff they stay away from, feel safe with the stuff that is downloaded by thousands of users, etc. and you'll never have reason to worry. I've been doing this since 2012, over 5 devices and not once have I had a scare bigger than a bootloop or a soft brick, and have never felt my information or safety was at risk.
If you are absolutely paranoid (I said IF you are) about some foreign country, some company, or some dev spying on you, exploiting your device, or stealing your information, rooting and customizing your device probably isn't for you. And that's not a bad thing, people make choices that are good for them.
But realize you are already at risk of most of these things, using a completely STOCK device.
If you want to experience an occasional bootloop, customize your device, learn how to use fastboot /ADB, flash diff kernels to see which one you can overclock for max power, or which one you can under clock for max battery life, or if you want to try the talents of diff devs who offer diff features in their cust Roms, if you want to learn all about the rooting, flashing, customizing world and help others learn about it; then you DEFINITELY want to unlock, root, and install cust Roms on your device!
The bottom line:
If you NEVER try it, you'll always wonder what you're missing, if you would've had fun tweaking, and customizing your device; and that'll suck
If you try it, and find out you don't like the risks, or the learning curve or the awesome experience of tweaking your device, you can ALWAYS, at any time revert to stock and walk away. BUT, you will have tried it. And that DOESN'T suck

A whole chunk of the code used in ROMs is open source. You can perform an audit and check it.

Announced vulnerabilities receive patches from google/companies and merged periodically.
Also THOSE same vulnerabilities allow us to root the devices.
So if you are "concerned" about security then you should not root the device.
Rooting and unlocking bootloader is meant for experts only.

Why is there only 1 custom ROM while we are 2-3months in already?

There is Scorpion and thats it? I thought it will be as good as with OnePlus or even better?!
Because the stock OS/ROM kicks so much ass. IMO

Go compile one then, it's not that hard to do. You can't just expect developers to feel obligated to everyone here on XDA. Devs usually compile and work on things when they have time away from their daily duties.
In fact, there's actually multiple ROMs, but they're not posted here on xda yet.

Same thoughts here. Stock and a custom kernel is all I need.
LOL. What a completely entitled thread. I'm surprised no one has called out the OP.
It's people like you that push away our development. Put a bad taste in a talented persons mouth who wanted to make a rom but not for those who feel entitled to one. What does your post accomplish? It's not going to encourage more development that's for sure.
As others have said there's more ROMs out there, but I wouldn't be surprised if the reason they haven't posted it here is because the community here on XDA can be toxic when people group together to complain about the lack of ROMs or how what is available isn't good enough. Be happy that we do have a rom here, or go out and build the rom yourself.

honestly i think we just need a good few magisk modules and the *need* for modified stock roms goes away, we'll still have AOSP roms being developed for. just have some patience
Probably not the best approach to getting more ROMs is calling out the forums for lack of them for a device that is still "new". Take a breath and be patient, sir. These things take time.

I'll actually agree with this. This Pixel 3 XL I own is the first time I've run Android stock in a long time and actually like it. My device is on the Pie December update and only rooted with Magisk, a few modules like Active Edge or ViPER4Androi0d installed, and ElementalX kernel and performance and battery life is quite good. Unless some serious custom ROMs like ResurrectionRemix (which I loved on my Nexus 6P) make it over, I probably won't even bother with a custom ROM.
This a hobby development forum! People provide work here as a hobby! NOT as a job!
XDA was created by developers to share knowledge...knowledge that members could use to create their own work!
Before you ask the question "why are there so few ROMs?" perhaps ask the question why you haven't learned how to create your own and contribute to this site.
Last I checked Google is not giving these devices away...they cost $900!!! Have you thought that maybe most developers chose a different device?
This thread has run its course.

Why is the (exynos) devlopment so dead & sloppy ?

Wassup Guys,
First of all, I wanna thank every developer in this forum here for providing us with free custom roms and mods for our device. I got a G986B by myself, but I neither rooted my device, nor did I install a custom rom. I wanted to install the latest stock debloated by hmy65, sadly my device type is not supported yet.
This brings me to the question, why there are so less projects in comparison to the amount of people being active here? Besides the reason, that Samsung is not providing every source tree or similar, I am wondering why there are so less custom roms currently ...is it because of massive amount of variety between the model itself? I am a developer too, sadly I am not a pro regarding building custom roms... although I gotta admit that I am interested in learning it. Well, what do you say? I mean like the S8,S9,S10 had plenty roms avaible at that time (speaking about the passed time since the device's release).

Well, that's true. But I guess I speak for the majority, when I say that Samsung and Snapdragon is not always a perfect combination. Well, I'd actually build something by myself but I doubt that someone can learn that fast ??

Question Experience with MIUI Mix?

Hi all,
Can somebody tell something about his/her experience with MIUI Mix ROM? Especially in comparison with the xiaomi.eu ROM? Both information about the stable as the weekly ROM are welcome.
Kind regards,
Thomas
I just dirty flashed MMX v21.6.23 directly over miui.eu ROM v21.6.23 without wiping anything (except Dalvik) and it works perfectly.
It looks extremely similar for me, just maybe more smoothly (Placebo effect?)
Let me check power consumption tonight and report.

Hi. although they are Devices different and Processors different.
I hope this personall opinion can help you understand some points to be considered, especially the use of battery by rom mix vs. rom me
SOT should be about the same, however standby is much better.
Definitely a smoother experience versus Xiaomi.EU and lots of useless tracking bloat removed.
Giving credit to where it's due, still Xaiomi.EU's work with Team MMX optimizations.
Thank you all so far for the great comments!
As promised, I measured the standby power consumption during last night (see attached), and indeed it was much better (mostly 0.12%/h) than the previous night with miui.eu (see second attachment)
I hope it helps.
I wouldn't recommand this rom as it seems closed source and no info whatsoever on developers but a telegram channel. Could be spyware/backdoor in it. Or maybe I'm wrong. But I won't trust it.

OK but MIUI itself, while based on opensource Android but adding a lot of proprietary components, isn't really open source !
So obviously, MMX cannot be more open source than MIUI (Xiaomi) itself

Been using MiuiMix on my Mi Pad 4 for 3 years, if they wanted to steal credentials they would have a long time ago.
My Mi Pad 4 was rooted and I purchased lots of apps from the play store with it, never got billed for something I did not purchase.

MMX got removed from so many Telegram devices channels for a reason. Do some research guys, it's not a safe rom.
Alright, I'll look into it.

I cannot find a lot about it, and MIUI Mix in general (which indeed maybe a red flag on itself). Could you maybe point us to your source?
MiuiMix posted their roms on XDA just like many other new custom developers in late 2017 to early 2018, this is the time I bought my Mi Pad 4 (unlocked from seller).
I've look deep into the files and services that runs on the rom from fresh install, seems to be no signs of spyware, but of course I'm no security expert (only took two courses in college).
My reasoning for them being kicked out of so many Telegram channels and disappearing from XDA would be their roms are not based on their own work and there's probably lots of backlash from the developers of Xiaomi.EU and the general custom rom community.
I'll say this though, I totally agree Xiaomi.EU is the safest bet to whomever wanting to run a custom rom based on MIUI given they debloat those Chinese tracker apps still left on Xiaomi.EU rom.
This is obviously one of the the reasons why like MiuiMix (it's very clean, Chinese tracker apps removed), but then again I might be dealing with a super sophisticated spyware app baked into the rom.

I know the team,have a group on telegram with any info,and the rom is a modified eu with some tweaks,every rom is tested before,no backDoor or spyware in it.
