[Q] a thing or two about kernels ??

i was just wondering what these kernels do . need less of that i read everywhere that our devs were waiting for huawei to release official 2.3 so they can get the kernel .
isnt it possible that we can make our own kernels or now as we have new kernel so can we expect new cm7 or xygen or miui to come out with an awesome flawless rom ????? surely the touch is much smoother on official 2.3 n camera has significant improvement ( UI is childish )

On the "what these kernels do..." check wikipedia, Android Kernels are based on Linux kernels. In just a few words kernels provide the basic functionality for applications to work (devices, memory management, process management)
Developers wait for the kernel source code (which is a 2.6.35 kernel), not the binary that is included in the official ROM (thankfully, Huawei is obligated to release the source).
When kernel source is released, any developers that want to build, tweak, study, copy, use the kernel source can work their magic *crosses fingers for CM7*

need an official custom rom for redmi 3s(land)

I am afraid what you are asking for is impossible. Once it is a custom ROM it is unofficial.

I mean a custom rom based on official kernel source.

Well, the kernel source was released in early January and we are in May. You may have to kidnap a developer and force him to make a ROM.

ha ha ha

forget it ,only hope is aex ,lets see what darshan is cooking

What I like is how everyone seems to want this or that custom ROM but as soon as you ask them to donate towards a Redmi 3S for the developer, they are nowhere to be seen. That's a good demonstration of how much they care about the developer's work.

The LOS of Fedosis is very stable. For my taste it's very near to official...
There's only the darkvideo bug left...

new to the forum

So im new to this forum but not to rooting and flashing. Basiclly though im thinking of rooting but not sure there are any stable roms worth flashing and any issues i should look out for. Someone please help me get back into rooting n flashing on op5. Thanks in advance.

Codename Phoenix and Candy ROM are the two most stable and smooth Oreo ROMs that I have used on the OP5. Most custom Oreo ROMs for this phone have bugs, are missing features or don't run all that smoothly. The majority of the Nougat ROMs and kernels for OP5 aren't going to be updated to Oreo because most developers have abandoned the phone since it was only sold for 4 months and unified ROM development for the OP5/5T appears to be impossible. Unless you are one of those people that buys a new phone every year the OP5 is going to end up being a terrible purchase. The Codename Phoenix dev is talking about getting a new phone (definitely not from One Plus) and abandoning his ROM for this device. The dev of Flash Kernel switched to a Pixel 2XL and might also abandon development for this phone. If you use a non-OOS ROM Flash and Blu Spark are the only two custom kernels left that you can flash.

There's xXx romb No Limits. It's VERY stable. Based on oxygen os. I'm running this for a very long time and had zero issues.

IS it worth to install custom roms?

Like the title says, is the original rom good? Or should i go custom right as i boot it 1fst time

It worth it, at least you get the notifications work correctly and shows at the top of the status bar unlike the stock rom..
My advice to you is to istall lineage only, it's the most stable rom so far.

It depends on your priorities, if you want more choice, more control on what apps are pre installed, no bloatware, and more customization options, then that's what custom roms are for. But mind that it comes with lower security, at least as long as the manufacturer updates the device. Because custom roms usually run with looser security settings and features.

does custom roms fix the touchscreen lag on the edges?

Not worth it yet. Wait till official lineage and official trwp are released. More risky to use custom roms whose source codes are not released.

as i've seen and read in the forums, the unoffical lineage rom seems to be very stable already. Which problem do you see in flashing this version now?
My bootloader is unlocked in 3 hours and i want to get rid of this EMUI crap and bloatware

You don't get updates on unofficial versions and it's not as well maintained/supported as name implies. I rather keep bootloader locked and secured, and get almost monthly updates from xiaomi. Until official TWRP and LOS are released, as stated earlier. No need to rush and deal with instability or unexpected problems. I debloat unnecessary apps using SAKI program on stock room without root. I honestly think this is the best path to go for now.

I won't install any custom roms before official TWRP support and official LineageOS ROM support comes. I'd not also unlock my phone's bootloader untill those two thing comes.

I switched to Pixel Exirience rom from the global 10.3.5 and touch latency on the edges still the same.

I don't know what custom rom users priorities are, mine definitely having a smooth and proper working device. Most roms I tested in the past simple but most used features, like the camera, were always a headache. It might make sense for a techie or geek, but for daily use I'd rather debloat MIUI for mind peace...

any of you guys installed xiaomi.eu? seems like the better version of miui IMO.

have you tried flashing another kernel?

Maybe THIS can help you with your choice.

The Evira Kernel is built into the PE, so i just updated it to the last 1.9 version and did not feel any difference.

If you just want to get rid off the bloatware, just use adb commands. No unlocking and rooting needed

If you got the 3GB/32GB variant. then lineage OS or pixel experience should save you some extra GBs of storage and free you some extra ram (MiUI 10.3.5 uses 1.6GB or something IDLE and leaves you with 20GB storage with stock apps)

It is to early. You have latest version of Android OS on your phone, and Xaomi still give us updates with some new features.
Custom Roms are still developing and have some bugs,so .. I will no rush with installing custom rom yet. Thats my opinion.
When Xaomi stop supporting us and giving us updates,after one year that is sure that will happen,than will custom ROMs will be fully developed..and can install it..
I would like to have custom rom ,and Elvira kernel, I like tweaks and mods from Magisk. But also I want to see MIUI 11 and next Xaomi updates for RN7.

As soon as I could, I unlocked my bootloader and installed AOSP (GSI).
I don't really like MIUI, it has a lot of nice features but actually I don't use most of them.
For me, it's worth.

What is the difference between OFFICIAL custom rom and UNOFFICIAL custom rom ?

Anyone plz tell me
Thank you.

Official ROMs are usually better supported and have a quality certificate from the developers. There aren't many official ROMs for lavender now, but for example the unofficial OTA LineageOS is both full-featured and stable enough for daily use.

Why UNOFFICIAL roms are not getting OFFICIAL for lavender ?

Because the devs don't have time to support them. They would need to do it to remain official.

Official roms require commitment from the dev, like periodic updates and not filling the rom with features not present on other devices...
