ROMs + Recovery + Root

Is the A3, A5, A7 series bad for dev of ROMs and new mods on sites like this? I saw someone that wrote something about that. They mentioned it was due to the Exynos chipsets. Could have been the 2015 or 2016-series also.
No, it is misunderstanding in the early days it was like that but times changes.
Look at the s7 exynos full of dev support.
It is a new phone, give it time.
It is always like that.
Samsung release even the open source files maby it is not complete but u could port cm 13 or lineage os by yourself to the device and get things working.
Or build a kernel etc.
Twrp same it can get official but we get someone who is mainly focus on dev twrp for our devices.
I dont have much time and i will focus mainly on the stock os.

Memory needed for lineage?

Can I find a list somewhere that tells how much internal and RAM memory each version of Lineage OS needs?
And, I guess older versions often need less memory than newer versions?
I am thinking about to install lineage OS 14 on a Samsung Galaxy S4 mini.
I have found out that there is a Lineage OS 14 version for this phone.
But, can I find 13 or 12? If so, do the need less memory? Would it be better to install a older version?
And, how stable is lineage OS 14 for this phone?
And will Samsung Galaxy S4 mini works as a USB host with Lineage OS 14 installed?
For s4 mini specific information please go to device sub forum.
Here some general considerations: People often say old devices are too weak for modern android versions. I think this is a legend promoted by device markers for not providing updates. Early users of new versions often confirm that legend. But they compare stable old versions with unstable new versions. Nougat is OK now.
Regarding storages: main difference between nougat ROMs is preinstalled apps. They get even bigger by installing gapps. MicroG is a resource friendly (and privacy oriented) replacement for some gapps features.

Official LOS14 running fine on my S4 Mini & very stable (though dialer has crashed a couple of times when answering a call but I am the only person who seems to have this… maybe due to to fact I used the migration tool for moving from unofficial LOS14 to official LOS14 to move from CM13 to LOS14, so I can't complain) Install TWRP fromS4 mini neozone thread & update modem also if available for your S4 Mini version.
Ok, thanks.
But it would also be nice to know how much memory lineage OS need. It would be better to find a smaller phone than the samsung galaxy s4 mini, but how do I know if I can install lineage on it?
On gsmarena.com I can find alot of information about all phones, so I can see how much internal and ram memory all phones have.
Yes. It is not easy to find a small phone with good lineage support. It's not like Linux for PCs, where ram and disk space are the limiting factors. For custom android you need someone to build a ROM or do it yourself. S3 mini or moto e are OK.

Looking for a compliant device I can buy close to 139x70 size like Galaxy A5/J5/S7

Hi,
I'm looking for a device close to Galaxy A5 size and performances which I can install Microg-LineageOS.
Samsung is not good since firmware upgrades of 2018, can't go back to nougat with my Galaxy A5 SM-A520F, so stuck without MicroG and LineageOS 16.0 beta.
Any recommended device wich is not PITA to install LineageOS-MicroG please?
Or any workaround to downgrade my SM-A520F to Nougat ? (backups, tricks, anything apart Odin that is not working because of the new firmwares)
Thanks
Can I buy a Nexus 5 with any stock ROM ? Seems the good specs

Your device is a snapdragon model and the G960F is an exynos model
I said 960f just as example, but there's is any variant I can use?

Upgrade GALAXY TAB S 10.5 SM-T800 to the most recent Android version possible

Hi all,
I am the old owner of this device and was wondering to which latest possible Android version can I update it. Even unofficially supported ofc. Currently running 6.1.
Any helper links are welcome.
Thank you.

Hi, I updated my Tab S T-800 with Resurrection Remix based on 14.1 and it works really great.
Tried LOS15.1 too, but wasn't stable.

Good Luck
Guys, I have Samsung Galaxy TAB S (SM T805) if I update it to a newer version will it be faster?

Newer firmware doesn't necessarily make the device faster. There isn't much you can do about a 9 yr old device.
Since the T800/T805 are not Treble compliant, the only way to run newer firmware is via custom ROMs, although I doubt development on devices this old gets much attention.
So what I understand is there is not much to do with the tablet to make it a little bit faster.
What about root or that is a different matter?

Root is a different matter. In most cases, you can flash the Magisk app through TWRP, and Magisk will automatically detect the right way to root your device. If TWRP is not available, you'll need to patch the AP firmware file in Magisk, then flash to your device with Odin.

Would you be able to suggest which old tablets could make sense to flash semi-current roms onto? I tried to bring back some old device to reuse for home assistant display, but it's too old... Been thinking about these samsungs, but from this thread it's also a bit too old.

I don't have any suggestions, sorry. I have a Galaxy Tab A 8.0 (T290) at home that I'm running an AOSP GSI on, but those were released in 2018.

imho it's correct that a custom ROM doesn't necessarily make old devices faster, but I experienced it such that at least they don't get slower (except I9195).
Recently I was allowed to support development of Android 19=LOS 20 for my T325 and it runs like hell.
P600 and P900 on LOS14, T810 on LOS19 all using daily in different rooms.
I9195 on LOS18 (that is really laggy) N910F on LOS18 as backup devices.
