This repository has the following patches such as:

• Enable NFC service

• Bypass safe volume warning dialog

• Enable call recording

Original source code repositories:

• GitHub - LineageOS/android_hardware_samsung_nfc

• GitHub - LineageOS/android

Usage

Follow Lineage OS for Samsung S5 Neo guide until brunch s5neolte command. Before issuing that command, you need to put files of this repository in place.

Some notes about the official LineageOS build guide

• DO NOT install recovery.img. LineageOS Recovery is horrible, TWRP is great. Use TWRP. Thanks. If you mistakenly install recovery.img anyway, getting rid of it requires use of heimdall to flash back TWRP recovery.img (heimdall flash --RECOVERY <twrp-recovery>.img)

• Install only contents of LineageOS zip file lineage-18.1-YYYYMMDD-UNOFFICIAL-s5neolte.zip using TWRP

• You may already have repo command pre-installed on your system

• Use command repo init -u https://github.com/LineageOS/android.git -b lineage-18.1

• ./extract-files.sh commands relative to LineageOS source dir:

  • device/samsung/universal7580-common/extract-files.sh

  • device/samsung/s5neolte/extract-files.sh

  • Both must be executed

• In order to ./extract-files.sh commands fully succeed, you must have Samsung Android 6.0.1 preinstalled on your phone. Otherwise you get errors for missing files.

LineageOS requirements for s5neolte

• If you have original Samsung Android OS installed, it must be version 6.0.1. LineageOS installation on phones using older Android versions (5.1.1, etc.) simply fails.

  • If you do not have Android 6.0.1 , get official Samsung update with samloader. Extract zip and tar.md5 files, until you get all required .img and .bin files. Flash extracted .bin and .img files with heimdall

    • Samloader Arch Linux PKGBUILD (AUR)

    • Take backup with TWRP before issuing heimdall commands

    • Relevant files are as follows: boot.img, system.img, userdata.img, cm.bin, param.bin, sboot.bin, modem.bin, cache.img, hidden.img

      • If you use custom recovery such as TWRP, do not flash recovery.img

      • File S5NEOLTE_<XXX>_OPEN.pit is a partition definition file. You may extract one directly from your phone using heimdall, as well.

    • You must patch heimdall to successfully flash your Samsung S5 Neo phone. Compile heimdall, and apply patch file misc/heimdall/patch_filepartindex.patch. See this GitHub issue for details.

    • Heimdall source code: GitHub - alexax66/Heimdall

    • Heimdall Arch Linux PKGBUILD

    • Heimdall usage and command explanations: SAMMobile - [Firmware]Restoring Stock Firmware with Heimdall

    • Heimdall flash command for Samsung S5 Neo: heimdall flash --BOOT boot.img --SYSTEM system.img --USERDATA userdata.img --CM cm.bin --PARAM param.bin --BOOTLOADER sboot.bin --RADIO modem.bin --CACHE cache.img --HIDDEN hidden.img

      • WARNING: Use absolutely correct, Samsung provided files in heimdall command. Otherwise the flash process may fail and you end up with a bricked phone.

      • Flashing USERDATA is not necessary

Additional tips

• You may build parts of LineageOS using mm and mmm commands after sourcing build/envsetup.sh

  • This is useful for partial patches

  • For instance, building only Dialer APK, run mmm packages/apps/Dialer in lineage source root dir

• If in any case, you get error message cmd: unknown variable '$(PATH_OVERRIDE_SOONG)', run breakfast <lunch-command-option> command at Lineage OS source directory root again before issuing any other commands. Running breakfast command can take 10-15 minutes without any visible progress displayed

• Before starting Lineage OS, you may need to wipe cache & Dalvik cache in TWRP (Wipe -> Advanced Wipe -> [Dalvik / ART Cache, Cache])

Init.d support

No, do not use /system/etc/init.d/ or look for such folders. Simply put your boot time scripts into /etc/adb/service.d/ folder, set their owner to root:root and permission bits to 0700. You may give less restrictive permissions at your own risk. Default owner of these scripts seems to be root:shell. You may use TWRP to set owner & permission information.

Optionally, folder /etc/adb/post-fs-data.d/ may be used, as well.
