Don't know how to answer your question as devs on XDA are not paid to do this... it's more of a hobby. No way to tell what's going on in their heads. Also, custom ROMs and kernels is not a real complaint about a device.

Because the Tab S2 uses Samsung's own Exynos 5433 processor, which is a lot harder more difficult to work with compared to Qualcomm's Snapdragon processor.

Good insight. I'm awaiting delivery of mine right now, but I have noticed that it doesn't have the Dev support that devices released around the same time do. I got this largely because it has at least one custom ROM - thanks BigBot! - but it would be nice to see some of the more popular ROM support it too. I have no idea what I'm doing, but if I find the time, I may take a stab at cooking something up myself. Gotta wait for it to arrive first though!

It's not that the cpu is harder to work with, it's just that samsung are tight with the source code.
Qualcomm are much more forthcoming with theirs.
Also Samsung purposely attempt to prevent custom development and modifications to devices they build.

Add to that, that if many devices use the same processor or processor family it is much more likely that a developer will have one of those devices so he will be more motivated to to something with it and other devs can use their source. For example the exynos 5433 is used in the note 4 and that's basically it, i think, there is currently only raymanfx who's working with this specific SoC, so it isn't that easy. Concerning Qualcomm vs Exynos i'm actually not so sure about wether QC or sammy is more open right now, but if you compare for example the snapdragon 810, sd 808, sd 805 sd 800, they are often used in nexus phones, so there you have easy access to working with up to date source code. And since a company won't change that much regarding their best practices snapdragons will be similiar to other snapdragons and so on. The more a SoC is featured in different devices the more you will get dev support. Unfortunately that isn't the only criteria you will buy your device for, it might be a priority but certainly not the only one.

Just my two cents.
What shall developers to do? There are root, custom kernel, debloated stock, deodexed stock. There is ability to use Xposed and their modification modules. There are many launchers. What functionality we haven't and it is very important?

Exactly.
Simply flash a 5.1.1 stock ROM, root, debloat, use Xposed etc.
Then you have a wonderful device.
No need for custom ROMs or custom kernels.

True, which is why I prefer a lightly modified custom rom which I can customise.
Many rom builders go down the route of removing so much stuff from a stock rom that functionality is lost.
For me my tab s performs perfectly fine with the stock rom so I just customise it as I need.
I prefer the polished experience of a stock rom with all its bells and whistles on a premium device rather than removing all that and turning it into a basic run of the mill device.
To me building a rom is about providing a better experience with extra features and worthwhile tweaks not removing functionality.

I'm flashing back to 5.0.1. Dunno why but samsung seem to favour this over 5.1.1 . All the latest firmware are based on 5.0.2

I was wondering if 5.1.1 has an advantage over 5.0.2. ? (talking about T810)
For my region (LUX), latest available firmware is still 5.0.2. (and I have a feeling Samsung will skip 5.1.1 because of android 6 that's coming later this year)
I was wondering if it is possible to flash 5.1.1 XAC (canada) or XAR (cellular south) on my device (with region LUX) and if yes, will I have a better experience?
Someone has an idea?

I was on latest 5.1.1 now on latest firmware based on 5.0.2. There's no difference what so ever. If anything it seems a bit better performance wise. It had a huge changelog too on sammobile

Is there a recommendation out there for a root method for the T810? I just received one for my birthday
I just want to run basic stock and debloat.

I am new to the Tab S2 family. I got mine yesterday but I have been reading through the Galaxy Tab S2 section here on xda. While I agree there is a root method, it's not ideal as there is the KNOX counter problem.
I came from mostly Nexus devices which don't have such a KNOX system.
I appreciate all the developers/tinkerers here who have done what they have to get root access to the Tab S2, but I really which someone has hacked a way to reset the KNOX counter. As is, I'm very reluctant to root my Tab S2. I didn't pay to buy a new tablet to immediately void my warranty. Laws my differ country to country, but in the USA, one definitely voids the warranty if one roots and installs custom recoveries onto one's device. So it's imperative to defeat KNOX or at least be able to reset this KNOX counter that Samsung has on its devices.
I was not aware of this KNOX system on Samsung devices. It really does seem counter to the Android system which touts openness. I'm very anti iPhones/iPads because of Apple's completely closed off eco-system but Samsung seems to want a similar kind of closed-off system for its Android devices. Had I known about this KNOX system, I'm not at all sure I'd have purchased a Tab S2.
Anyway, I do wish there were more active developers tinkering/hacking the Tab S2.
Just my 2 cents.

Yeah, I agreed, that KNOX is big problem without help of community.
I investigated a few and read about solution on Galaxy S6 Edge. They have engineering bootloader (but Samsung bans all links) and it supports only 5.0.2 roms (it supports 5.1.1 too, but without fingerprint function).
So, we need ENG bootloader too

I'm not a dev but i could help with testing.
I'm just a noob (910V) ,, but I am willing to be a beta tester....very much looking forward to this build...
Sounds good, if you need help, here I am, but Telegram its a better way to do discuss :fingers-crossed:
I'm not a dev but I have a note 4 Sprint and can be a tester or do other tasks. I'm in!
Can we use something other than WhatsApp? I 2nd the telegram notion.
Remember when XDA used to have Logic and common sense ?
Let's go over this one more time
You want to port Android 8.0 to Note 4. Are you talking about porting official TW Oreo from Note 8, or porting all TW features - proprietary, closed-source Samsung code - from TW to AOSP?

Good luck with Porting a 64Bit System to a 32Bit Device... Simply not possible. And ported 64Bit Sammy Features on 32Bit AOSP? Mhh... The Note 4 may be the last good Sammy Device, but we will never see newer Samsung Software on it as Marshmallow Ports or pure AOSP/Lineage. Correct Me if i'm wrong but i think that's it....
Lineage 14.x is running great,if the drivers are there why slouldnt run a N8port dousnt run?

Well generally speaking when you port a rom (Nougat , MM whatever the case maybe) from a 64bit device, you dont port it as 64bit obviously unless the arch is unlocked and ready for it, you port it as 32Bit, the only limitation in terms of Touchwiz is when a certin app has only 64bit libs (Bixby voice is a great example) so even if you run api 24 (nougat) you wont be able to use such apps, But firmware side you can port it without issues, All 64bit phones include a set of 32bit libs aswell. and in terms of snapdragon Note 4 , yes you will never see a nougat or higher ""TOUCHWIZ"" based rom, Exynos however is already running Nougat.

As we all know you cant run TouchWiz based applications on AOSP (SystemUI / Launcher and many more) due to the fact that they require SEM codes (Samsung experience mobile), If samsung had their system sources up then you would have been able to, But just converting LOS 14 or AOSP to TouchWiz is just not gonna happen

because will never work since sammy needs his own android runtime etc etc for boot because it have methods etc needed from the framework etc. try to install the n8 launcher on lineage and you see what happens. it give fc. even after you add the missing method it will again fc and even when you add all missing methods that launcher needs in frameworks it will still fc because methods in the main libs are missing. and using sammy libs on lineage one is impossible since after some libs replace it will give a nice blackscreen
Hello,i have a question,the dates from the N4 and Nexus 6 are quite similar:
https://www.inside-handy.de/handy-ve...-galaxy-note-4
For the nexus 6 exists an Android 8 port,
https://www.getdroidtips.com/lineage...oogle-nexus-6/
So,is it possible to make from this one a poert for our N4??

I think it is possible to port Oreo to the Note 4, but not TW version of Oreo (in other words, include all Note 8 features in an Oreo port)
It will most likely be ported as Lineage or RR without the extra Sammy features, idk.

Custom Kernel support?

I have a general question about custom kernels.... Is a custom kernel specific to a device?
So can I currently install e.g. FrancoKernel or do I have to wait until it is supported...

A kernel is always highly device specific. It includes the low level interface to the hardware and as such needs the correct drivers for the individual hardware..
HIGHLY DEVICE SPECIFIC. I ran Franco for years on my Nexus devices but he'll never support a device he doesn't have and he'll never own one of these phones. Amazing Dev though. You can use his app still with these phones if you want to check it out

Why do you say he will never own one of these phones? He develops for pocophone, Redmi Note 3 and 4.

My mistake, its been a long time since I've checked in with Franco stuff :good:
Not only are custom kernels device specific but if you are unfortunate enough to own a device from XDA darlings One Plus there are separate kernels for Oxygen and non Oxygen based ROMs because there is so much code in Oxygen that veers from stock Android--in spite of the fact that reviewers always claim Oxygen is as close to stock Android as you can get. In reality Oxygen is as far as you can get from stock Android without buying an iPhone.
In spite of all the grumbling about MIUI and EMUI neither actually requires a kernel that won't boot up custom Android ROMs on the same phone.
I think that Mi9 will never get nice custom kernel. Mi9 SE has some, any SD855 has but not Mi9.. Dunno why. Kernel code was leaked before launching Mi9 sale.

I want 2016+ phones, cheap and which i can root easily, I'm tired to find any.
Generally speaking I'd suggest to check models that are in BOTH Lineage and TWRP official support lists:
https://download.lineageos.org/ (click on menu)
https://twrp.me/Devices/
That way besides stock ROM (probably not difficult to root because above availability) you will always have the alternative ROM + Recovery.

Also, check which devices are the most popular on XDA forum; there's lots of old but great flagship devices like the OP3 that are still getting tons of attention and are available on the cheap.
The problem is that most of your cheaper phones are either built intentionally to be tough to root, or ppl who buy them just don't care enough to do the extra. I know there was a midrange Moto a few years back and I'm sure it is still getting indie development, but the name escapes me... Try googling "most easily rooted phones" and see what you get. Might just need to get secondhand/older/foreign if cost is an issue.
Edit: just noticed your objection to older phones. You do realize that if you are going to root your phone anyway, you are 20x better off with a flagship 2014 model that has a Qualcomm 8xx PROCESSOR (or even most 7 and 6 series) than an Intel or almost any Mediatek processor? You don't need to worry about the age of it if it's in good condition and there's active development. THAT'S how you'll save money IMO.

Cheap? I'd say Xiaomi A2 or the Poco F1. Xiaomi bootloader is locked from the factory, but they have an official tool called Mi Unlocker to easily unlock it.
In case of Mi A2, released in 2016, since it's an AndroidOne device, you can simply unlock it using fastboot. It also has LineageOS and TWRP official support. From factory it came with Oreo, then updated to Pie. And they will release Android 10 for it at the end of this month (https://www.notebookcheck.net/The-X...edge-towards-Android-10-update.447310.0.html)
I'm running Mi A2 with Havoc OS v2.8 based on Android Pie, rooted with Magisk 20.2, and EdXposed 0.4.5. The device pass SafetyNet and can install Netflix from the Play Store.
They released Mi A3 with AMOLED display. But it's 720p with a notch, a downgrade from the notchless 1080p LCD display of Mi A2. But it has 3 cameras instead of two, and 4000mah battery instead of 3000mah in Mi A2, and will receive official Android 11.
Which phones are currently easiest to unlock, root and install ROMs?

Rooting and ROMs for Note 9?

Hi, I'm new here and also suck at all things tech.
I recently got the Note 9 and it's just a beautiful phone in almost all aspects. I'm having some problems with it, but that's for another forum. I want to ask here about rooting and ROMs. Can the Note 9 be rooted and are there ROMs available for it? If so, what is the easiest way for me to go about rooting it and installing a custom ROM? Do I look for computer and cell phone stores in my city and ask them?
One of my past phones was rooted and had a custom ROM. It was splendid just because of the ROM and from then on, I couldn't imagine having a phone I didn't root and get a custom ROM for. Unfortunately, since then, all my phones have been ZTE which-- at least for a long time-- didn't have any available ROMs. If this phone can be rooted and upgraded with a custom ROM, awesome. If I can fix the other issues first.
You didn't say what processor your phone has so here goes:
For Snapdragon CPUs: https://forum.xda-developers.com/f/samsung-galaxy-note-9-snapdragon-roms-kernels.8318/
For Exynos CPUs: https://forum.xda-developers.com/f/samsung-galaxy-note-9-exynos-roms-kernels-reco.8016/
There are many custom ROMs, kernels, etc here in the XDA sections. In my opinion NobleROM would be one of the best ones just from what I've read/seen about it.
But do ask yourself if you really need root and a custom ROM on the Note9. I'm a guy who could never imagine having an unrooted phone until I got the Note9 - it has everything I'd want stock and there is also GoodLock modules which are made specifically for OneUI by Samsung and don't require root.
PS: Just NEVER put a Snapdragon ROM/kernel on an Exynos phone and vice versa or you'll most likely brick it.

Question Custom roms?

Isn't there any custom rom for tab s8 ultra? My tab is now 1 yr old so was keen to experiment. Is linux a good option? Any advices please. I am just a tech enthusiast so just looking to have some fun.

There's actually no developpement for Galaxy Tab S8 serie. The hardware is pretty new and Samsung doesn't help users to dives into his hardware...
If you want to try roms, you can still install TWRP and try GSI.
About Linux, except using Termux, you can't do anything since the Kernel is locked and there's no way (yet) to enable KVM on snapdragon devices...

GSI (Generic System Image) is a kind of rom that (should) work on any Treble enabled device (aka almost any device that come with Android 11 and up).
However, on Samsung devices, most of hardware relies on proprietary drivers (like camera or spen...), so you should'nt expect them to work good as using Samsung firmware
There is not custom roms almost to none Samsung device any more. Samsung is trying to become Apple. Locking every device with many ways. Only root there is, and this more difficult every year. Unfortunately Samsung is still creating the best hardware , and good software, so there isn't very easy to go to another company for the most users..
