LineageOS is a free, community built, aftermarket firmware distribution of Android 11, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps) . LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

Base source code is available in the LineageOS Github repo. And if you would like to contribute to the project, please visit our Gerrit Code Review.

Build Compatibility:
The noted models are the only ones supported. If you have a model that isn't listed and ask politely then I might work to add compatibility.

Compatibility Notes:
  • Bootloader version doesn't matter. Anyone who tells you so doesn't know what they are taking about. My Developer Edition G900V is still running the original 4.4.2 KK aboot. My G900W8 is running the latest 6.0.1.
  • All builds except for klteactivexx and klteaio MUST be running a marshmallow (6.0.1) radio for RIL to work. If you are about to report that RIL/radio isn't working then I pretty much guarantee this is your issue.
  • You MUST be running a marshmallow (6.0.1) NON-HLOS for the fingerprint reader to work. If you are about to report a fingerprint reader problem then you either have old firmware (update it), your /data was previously encrypted and you performed a "clean" flash without FORMATTING /data (start over and FORMAT /data), or your reader is just broken.
  • External SD cards don't support POSIX (ext*, f2fs) or NTFS filesystems anymore. If this affects you then just bite the bullet, copy any data off you really want to save, and reformat as exfat.
  • The latest TWRP seems like it works, but if someone has issues then perhaps try using the actual supported recovery.
Donations:
  • I absolutely don't personally accept them. If you really feel that this work deserves it, then find a local food bank or animal shelter/rescue and throw some money their way. You can also throw some the way of LineageOS, but we're actually doing pretty well right now.

I tried this ROM yesterday on my Samsung S5.. It was fast. Unfortunately, I won't be able to use it as easier compared to RR rom.. My phone's power button is not working anymore. So in order to utilize my device, I have to rely on features like gestures or long press on navigation buttons. In the RR rom, there's an option for power menu on long press on buttons, as well as screenshot. May I request that this feature be included in future developments? Thank you so much!

Just updated to the 18.1-20211010-NIGHTLY-klte and I don't know what happened, but the battery seems suddenly to last for ages, thanks a lot @haggertk and all contributors!

@danielhuf: Believe me or not, but i can confirm this! I use my good old S5 as a desk phone with WLAN and LTE/GSM enabled. The most used app is the RSA key generator which i need for my job. The behavior of my usage has not been changed since more than 1.5 years now. Therefore i am able to recognize very small changes in battery lifetime. There are builds which have more or less battery drain. The 20211010 is one of the ones whith _VERY_ less battery drain! Therefore i will stay on 20211010 for the next weeks maybe until the next security bump in november or december. Of course i will use my dev/test S5 to update on a regular basis to the actual nightly build and report this here :cool:
Thx 4 supporting the S5!

I agree! Battery drain is way better then before. Hope they don't mess up over time. I advise anyone to archive that nightly build for a time. just in case if things go south again with the battery usage.

may be they will improve it even more which would be f***** awesome :D

My Device is Galaxy S5 Docomo Japan.
I have just installed the latest version of Lineage OS, but the problem is still there, since the last time I used the older version with Android 10 a few months ago.

What is the problem?
-Charging issue, not detected.
-Can't be charged when the device is not booted on, otherwise it will keep restarting.

Any update/fix for this?

AFAIK there is no fix in the current builds @ the present for the S5 kltekdi charging issue.

The S5 klte* maintainer haggertk never replied to this post. ¯\_(ツ)_/¯

Just curious: did you try booting in TWRP recovery & connect to a power adapter to check if it's charging?

Just installed latest build yesterday. No problems whatsoever. As usual, many thanks to the developers. A couple months ago, I received a Galaxy a71 5g as a gift. I took the SIM card out of my S5 and began using the new phone. When I found out that the bootloader couldn't be unlocked, I put the SIM card back into my S5 and it is now...once again...my primary phone. I might try to sell the other one or give it to somebody.

I have an issue. I've installed on my G900F. But when i try to setup offline, i can set the language and then the screen stays stuck at "Please wait..."

Any ideas what to do? I've flashed latest pico gapps, if that has anything to do with this.

Happened to me too on my g900f. Even on 7.11 crdroid. Even without gapps. Sometimes it will go through after reflashing, then when I go to "files" and the internal storage isn't detected. I think that's why it gets stuck at please wait.

Thanks for your asnwer.

I installed BitGapps R41 and cannot see both apps in Play Store even though SafetyNet passes with Success in BASIC evalType.

Did you install manually apks ?
Do you know where I could have done this wrong ?
Hmm, I installed both apps via Play Store, no issues there. Looks like Play Store doesn't see your setup as certified or something. Magisk usually is the culprit, because hiding root is a mess. One day it works, next day it doesn't. Especially with banking apps. That's why I gave up on bothering about Magisk. Since then my phone just works (especially the banking apps).

You can sideload the .apk, though. Try Aurora (Play Store alternative that pulls the .apk from Google directly), it will install the corect version, since it doesn't care about Google Play restrictions. Search for it and you'll find it.

Hi, you are awesome !
Didn't know about Aurora, everything is fine.
Thanks a lot,

    S5 LineageOS 18.1 Update 2021-11-28

    Using the built-in Updater I OTA updated S5 G900M LineageOS 18.1 klte build 2021-11-14 + MindTheGapps + Magisk 23.0 + TWRP 3.5.2_9-0 to build 2021-11-28: everything went smoothly as usual & GApps + Magisk survived the update.

    There are just a few minor changes listed in https://download.lineageos.org/klte/changes/ but I updated anyway so I could post about it.

    For some reasons some apps did not have their labels in the app's drawer but toggling off/on in Trebuchet's Home settings > Show icon labels in drawer fixed it.

    Thank you to the Lineage Team & Mr. haggertk for keeping our old S5 klte* up to date. :cool: 👍

    It's samsung s5 klte, updated with the Nov 21 update of los 18.1 last Sunday, and the previous updates before that. I cannot rule out that the error might be due to the phone, though, as I restored my older s 5 on the present one (see my post of sept 15 on this thread), but until now I have had no problems with updating. I'm not sure what you mean by add-ons, but I can't think of any.

    Yes, SM-G900F, BitGApps arm 11 (I think it was, but I may have changed to MindTheGapps at some point, I don't know how to check which one is on the phone now), Magisk-v23.0, and TWRP twrp-3.5.2_9-0-klte (I think, I would have to boot into recovery mode to check, does it matter?)
    2
    Updated my dev phone to build 2021-11-28 coming from 2021-11-14 Config is SM-G900F german/european version, no vendor brand, TWRP 3.5.2_9-0, open gapps "pico", no magisk, etc. All good, no problems so far.
    Thx to Mr. haggertk.

    Thanks for for build Japanase Galaxy S5(kltekdi)

    But since Lineage-17.1, I'm using modified kernel with EXTCON enabled.
    Without EXTCON, the Japanese Galaxy S5(SC-04F, SCL23) will not detect usb charge.
    and charger mode is looping reboot.
    Kernel with EXTCON enabled, EAR JACK will not detects.
    Is there a way to fix it?

    S5 LineageOS 18.1 Update 2021-11-14 - Android Security Bump

    Using the built-in Updater I OTA updated S5 G900M LineageOS 18.1 klte build 2021-10-24 + MindTheGapps + Magisk 23.0 + TWRP 3.5.2_9-0 to build 2021-11-14: everything went smoothly as usual & GApps + Magisk survived the update.

    There are a few minor changes listed in https://download.lineageos.org/klte/changes/ and some of them do not concern the S5 klte* family but most importantly it includes the monthly Android security bump: Bump Security String to 2021-11-05.

    After the automatic reboot as seen in the screenshot > Settings > About phone > press on Android version > Android security update: November 5, 2021.

    The Vendor security patch level just below it remains @ August 1, 2017 because the vendor is Samsung & it is not publishing security patches for it's S5 proprietary hardware related blobs anymore since August 2017.

    See Android Security Bulletin - November 2021 for details about the security fixes.

    Thank you to the Lineage Team & Mr. haggertk for keeping our old S5 klte* up to date. :cool: 👍

    yep, its worth to start looking around march or april next year. so enjoy the well working A11 as long as it is supported. Please be aware that alot of Samsungs stock android user need to wait much longer to recive A12 - if they ever will receive it. This is one of the big advantages of LOS.

    A large THX to all LOS maintainers! (y)

    LineageOS 18.1 for S5 Performance & Adoptable Storage

    how does the performance fare on this dinosaur of a phone with android 11?

    I works fine if you respect it's RAM & internal storage limitations.

    Battery usage is lower on my Galaxy S5 G900M LineageOS 18.1 klte compared to 15.1, 16.0 & 17.1.

    YMMV depending on how much stuff you add on top of LineageOS and how many apps you have running in the background.

    Battery & RAM usage depends a lot on the optional GApps package if you install one and the permissions you give to Google (Web & App Activity, Location History, YouTube History, Ad personalization, etc.) in https://myaccount.google.com/data-and-personalization

    The more data you let Google collect, the more active Google Play services as you can see in > Settings > Developer options > Running services. Disabling apps auto-update in Play Store > Settings > Network preferences helps a lot also.

    See the bottom of this post about optimizing MindTheGapps which I installed.

    i have an optimized 14.1 installed but it isn't cutting it in terms of adoptable storage.

    The S5 klte* maintainer haggertk recommends not choosing Internal storage for the Micro SD card (adoptable storage) when formatting the card in the device and posted about it here: "...my opinion is no one should use adoptable storage. It's a fragile mess and always has been since Google explicitly does not care about sdcards."

    FWIW on my Galaxy S5 G900M when it was running LineageOS 16.0 with a SanDisk Ultra 64GB microSDXC UHS-I Card Class 10 & using SD Card Test I got Internal SD card Read 223 MB/s vs. Removable SD card Read 40 MB/s so that's why I don't use adoptable storage & don't move apps to it besides all the problems it may cause. Write speed is about the same @ 25~27 MB/s. (screenshots)

    FYI from the post #1 > Compatibility Notes: "External SD cards don't support POSIX (ext*, f2fs) or NTFS filesystems anymore. If this affects you then just bite the bullet, copy any data off you really want to save, and reformat as exfat."

    i know 17.1 was dog slow and took a while to start

    If you are talking about a cold or hot boot, 18.1 is faster.

    If you are talking about waking up the device while in deep sleep, it's slow because Doze is very efficient in 18.1 & a bunch of stuff wakes up & wants to sync & do stuff that Doze blocks while in deep idle.

    BTW that's why apps like Greenify for example are deprecated in 18.1.

    i plan to use this as my daily until i get a new phone

    It is my daily driver. See the posts I linked to in post#4

    S5 G900V eMMC CID 11: Impossible to Unlock Bootloader

    I tried to install LineageOS 18.1 on Samsung Galaxy S5, G900v, eMMC CID 11...

    Sorry but you are out of luck & it's not possible to unlock the bootloader of your device.

    The sequence for the S5 SM-G900V is > Samsung OS > check if eMMC CID 15 > unlock bootloader > flash TWRP custom recovery > backup EFS partition > Flash LineageOS + optional packages if you wish.

    An unlocked bootloader is required to be able to install a custom recovery which in turn is required to be able to install a custom ROM like LineageOS.

    See this thread which is more on topic for your issue: [GUIDE] Root, Bootloader Unlocks, and More!
    ***

    Okay, here's a log I recorded via MatLog Libre. Steps:

    Start recording
    Press power to lock the screen
    Double-press power again to start the camera
    *Error connecting to camera*
    Unlock phone
    Stop recording, export log

    I hope that helps. The issue is already mentioned in this thread several times, not only by me. ;)

    Ah, only from lockscreen... yeah, I see it.

    It'll be fixed when this is merged: https://review.lineageos.org/c/LineageOS/android_packages_apps_Snap/+/319052

    SDcard corruption may be caused by a recent Google security patch. I experienced this once with the "new" unofficial LOS17 for the Samsung P605, coming from unofficial 14.1,where this never happened before. But others started complaining about the same issue, after this antique rom got a recent security patch.
    It's (likely) not. I've found an issue in the legacy paths of the recent sdfat (Samsung exfat driver) revision. I haven't been able to recreate the bug/assert after the fix. After getting a second confirmation I'll upload the merge the change.

    Every kernel < 4.8.y that had updated to sdfat 1.4.5 is affected.

    S5 LineageOS 18.1 Update 2021-05-09 - Security Bump, Camera U.I. Fix & Kill App Option

    Using the built-in Updater I OTA updated S5 G900M LineageOS 18.1 klte build 2021-05-02 + MindTheGapps + Magisk 22.1 + TWRP 3.5.2_9-0 to build 2021-05-09: everything went smoothly & GApps + Magisk survived the update.

    There are a bunch of changes as you can see in https://download.lineageos.org/klte/changes/ but of note:

    After the automatic reboot as seen in the screenshot > Settings > About phone > press on Android version > Android security update: May 5, 2021.

    The Vendor security patch level just below it remains @ August 1, 2017 because the vendor is Samsung & it is not publishing security patches for it's S5 proprietary hardware related blobs anymore since August 2017.

    See Android Security Bulletin - May 2021 for details about the security fixes.

    With the change Snap: use translucent control background on 16:9 the stock camera is showing the full frame preview again (screenshot). There are other minor Camera changes.

    Interesting also there is a new Kill foreground app option in > Settings > System > Buttons > for Home, Back & Recents buttons which is useful when an app is frozen or you want to prevent it from using some RAM in the background (screenshot). Note that it may make it slower to open that killed app the next time you want to use it.

    BTW you can create a direct link to Updater & much more with the LineageOS Settings widget. I stacked a few of them on Home to create a LineageOS shortcut folder for quick access.

    Thank you to the Lineage Team & Mr. haggertk for keeping our old S5 up to date. :cool: 👍

    Galaxy S5 LineageOS 17.1 Upgrade to 18.1 + OTA Update Success Using TWRP

    I upgraded my S5 7 days ago and did not lose any apps & settings: Galaxy S5 G900M LineageOS 17.1 klte build 2021-04-18 + Open GApps Pico + TWRP 3.5.2_9-0 >>> LineageOS 18.1 klte build 2021-04-25 + MindTheGapps for Android 11 ARM + Magisk 22.1 which I just OTA updated to LineageOS 18.1 klte build 2021-05-02: everything went smoothly & GApps + Magisk survived the update.

    The only major issue is the unusable stock Camera as described here: LineageOS Snap Camera U.I. Not Showing the Full Image Preview. Edit: Good news, following a conversation with a dev this commit was merged & will be included in next build: Snap: use translucent control background on 16:9.

    Note: three S5 users so far AFAIK, including @Massedil in his post here, reported not being able to unlock their devices after upgrading to 18.1 from 17.1. I always disable screen & SIM locks before an update or upgrade just to remove variables that may go wrong.

    Old versions of TWRP may fail to apply OTA updates. See How To Update TWRP Using TWRP Itself.

    BTW don't install the TWRP app when offered in TWRP as it may causes bootloop because LineageOS is enforcing priv-app whitelisting rules.

    Several S5 klte variants users reported failed to boot on 17.1 with a modem older than Android 6.0.1. This may also cause No Network or No Service issues on 17.1 & 18.1. See S5 Odin Flashable Modem & Bootloader.

    Also before a major upgrade to a higher version but not before regular updates: Magisk > Uninstall > Restore images to preserve my Magisk settings & modules while disabling Magisk (screenshot).

    Re-flashed Magisk-22.1.zip after successful boot to System after the upgrade.

    MindTheGapps is similar to Open GApps Nano. See Open GApps Package Comparison.

    Searching apps with Google in /System:
    • Android Accessibility Suite
    • Android Auto
    • Android Setup
    • Data Transfer Tool
    • Exchange Services
    • Google (search app)
    • Google Calendar Sync
    • Google Contacts Sync
    • Google Partner Setup
    • Google Play services
    • Google Play Store
    • Google Services Framework
    • Google Text-to-speech Engine
    • Market Feedback Agent
    • Markup
    You can also download the MindTheGapps package, unzip & search it with apk.

    You can disable the Google's search app with it's optional personal data hungry Assistant in it's app info. Which I did because it has too many running services for my taste.

    AFAIK from the available Open GApps for Android 11 test builds 20210130 @ the present, only the Pico package was reported as issue free in the Open GApps support thread on XDA: GAPPS DAILY Open GApps for Android; All Android Versions & Devices.

    I have been an Open GApps Pico user for years on several devices but since there are no official releases for Android 11 @ the present, I decided to test MindTheGapps because that's what LineageOS links to @ the present in https://wiki.lineageos.org/gapps.html and wanted to post about it.

    See https://wiki.lineageos.org/devices/ > {device} > Upgrade to a higher version of LineageOS.

    After a full TWRP backup (including the important EFS partition but except the Cache) & triggering a fresh Google Backup* (Settings > System > Advanced > Backup in 17.1), I did the same steps as described in that upgrade guide except that I use TWRP 3.5.2_9-0 so sideload must be started manually on the S5 before sideloading from the computer: TWRP > Advanced > ADB Sideload > Swipe to Start Sideload.

    Or simply copy the files to the device & flash from there using TWRP.

    To make the TWRP backup smaller I use SD Maid > AppCleaner to clear the cache of all apps & make sure to delete all downloaded updates in Updater by long pressing them or if rooted move them from /data/lineageos_updates/ to external or internal SD Card.

    In case of failing to boot you can restore only the System, Data & Boot (boot.img is actually the kernel) partions from the full backup.

    Obviously there are other backup methods but that's the one I use since a couple of years & restored them both successfully.

    On some devices, some versions of TWRP do not work well with LineageOS 18.1 and the Lineage recovery is recommended in those cases but on my S5 klte, TWRP wins hands-down with it's backup/restore feature, File Manager, installing both manually or via sideload & applying successfully OTA updates so I don't see any reasons for switching to the Lineage recovery @ the present.

    Tip: to make the S5 18.1 U.I. faster & more fluid when opening the apps drawer, scrolling through home pages, opening Settings, etc: > Settings > Accessibility > toggle on Remove animations.

    Try it before & after as fast as you can to see the difference.

    *: Warning for people using a pattern lock screen see this bug report: Google cloud backup cannot be restored when using a 4x4, 5x5 or 6x6 lock screen pattern

    S5 LineageOS 18.1 Update 2021-10-10 - Android Security Bump

    Using the built-in Updater I OTA updated S5 G900M LineageOS 18.1 klte build 2021-09-19 + MindTheGapps + Magisk 23.0 + TWRP 3.5.2_9-0 to build 2021-10-10: everything went smoothly & GApps + Magisk survived the update.

    There are quite a few changes listed in https://download.lineageos.org/klte/changes/ but most of them do not concern the S5 klte* family.

    Most importantly it includes the monthly Android security bump: Merge tag 'android-11.0.0_r46' into staging/lineage-18.1_merge-android-11.0.0_r463.

    After the automatic reboot as seen in the screenshot > Settings > About phone > press on Android version > Android security update: October 1, 2021.

    The Vendor security patch level just below it remains @ August 1, 2017 because the vendor is Samsung & it is not publishing security patches for it's S5 proprietary hardware related blobs anymore since August 2017.

    See Android Security Bulletin—October 2021 for details about the security fixes.

    Thank you to the Lineage Team & Mr. haggertk for keeping our old S5 klte* up to date. :cool: 👍

    I found a weird workaround fix for my recurring Quick tiles & status bar curtain long press System UI crashing but that's for an other posts.
