LineageOS doesn't retain older versions if I recall so you would be jumping to Android 11. Which is NOT a bad thing given Android 6 is years out of date.

EDIT: As a FYI while my S4 long since ceased being my daily driver I have kept it updated and am running the latest version of LineageOS on it as we speak. It's certainly a better choice as a backup than my Nexus 6, simply because the battery is easily repkaced.
Hi @Strephon Alkhalikoi usually most recent rom are less stable? for example a lineage os based on android 6 or 7 is more compatibile and safe compared an android 11? probably for more compatibility of code/driver etc?

I don't need a rom for nerdy things, but only for great stability and use app for my work, phone don't never crash or reboot

It used to be true that more current versions were less stable, but that hasn't held true for some time. I've never had stability issues on this device. Same holds for my Pixel 2 XL but I digress.

All I can recommend, if my recommendation isn't acceptable, is to play around with the available ROMs for the device and test them to see if they meet your requirements.

Hey everyone,

as this is a noob-friendly thread, I hope I'm in the right spot :)

I will get my hands on a stock ROM Galaxy S4 LTE (GT-I9506) soon (I don't have it at hand right now).

As the stock ROM is very old and lots of newer apps don't even bother starting anymore, I want to flash a custom ROM (LineageOS 18.1). I did read through the entire thread and I have flashed other phones previously, still I have some specific questions as I haven't flashed any Samsung devices so far (I'll try to be as short and specific as possible):
  • Is there no need to unlock the bootloader of the GT-I9506 before flashing (anything)? I can't seem to find any instructions, so that's my assumption.
  • I will be using ODIN 3.10.7 from here, is that ok?
  • Is it correct to flash TWRP via the AP button in ODIN?
  • Is it correct to flash bootloader/modem via the BL button in ODIN?
  • When should I flash modem/bootloader? Together with TWRP? The instructions don't mention this, here it is done simultaneously however.
  • Is the modem/bootloader file mentioned in the collection thread the only one for the GT-I9506 or do I have to backup the phone's specific modem/bootloader? Can I just flash modem/bootloaders back and forth like recoveries (in case something goes wrong)? Anything specific to check/look out for (besides model number)?
  • I will take a full backup using TWRP ASAP. Will it contain the modem/bootloader or do I have to restore it separately (with the file from the collection or the dedicated backup respectively)?
  • Is OpenGapps ARM 11 pico a proper version?
ADB and drivers are installed properly on my PC, I will check ODIN detects the device properly when I physically have it with me.

Thanks for the help and best regards.

From my experience, you cant **** up easily.

If Odin 3.10.7 doesn t work use another one, trial and error until u find something that works dont worry about it too much
Also i suggest you use drivers from Kies

If i remember correctly, when you first try to flash anything the phone asks you wheather u want to unlock the bootloader and when you press yes( i think its the up volume button ) the knox thing trips

About modem/bootloader I dont remember doing anything to it its been a while. I had just installed TWRP and did everything from there.

Dont use any files for GT-i9505 or GT-i9500. They have different processor and probably wont work.

About Gapps i suggest you use those from opengapps.org, cant remember wheather its ARM or ARM64. When you try to flash them from TWRP an error will pop up if its the wrong version, again impossible to **** up.

I suggest taking backup of everything before you try anything.

I remember struggling a lot to find some files i needed once so if you can, backup all the stock files and upload them for the community

Hope I helped, have fun and tell us how it goes😄

Hello, hope this is the right place for my question.
I flashed my glorious Galaxy S4 with LineageOS 17.1 (tried 18 but a few apps wouldn't work, so flashed 17.1) and so far it's working great, it's given a new lease on life to my phone.

The problem is that whenever I turn on the speakerphone, my phone goes into mute and the other party can't hear my voice, even if I shout near the microphone. If I turn the speakerphone off the conversation can continue as normal, but obviously I have to keep my phone near my ear. Is it a LineageOS bug?

I recall having problems with the noise suppression feature with the stock ROM, I had to turn noise cancellation off in order for the other parties to understand me, but I can't find the noise suppression setting in LineageOS 17.1. Hope someone can help.

If this is not the right place for my question, please direct me towards the correct forum.

This sounds like a rom issue I don't think there is much you can do about it.

Excuse my ignorance. Can't the developers fix it? Is there some channel I can report the problem through? Is there any alternative phone app that might work? Thanks!
The developer can and probably will eventually fix it. Now I am not sure whether an alternative phone app will help, feel free to try it out. The place where you got your rom from is the place to report bugs and please send a log cat together with the report developers love those.
