[ROM][13.0][UNOFFICIAL] LineageOS 20.0 for Galaxy A51 4G

[Royna]

LineageOS is a free, community built, aftermarket firmware distribution of Android 13, 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. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the changelog for a full list of changes & features.

What's working:

• RIL (Calls, SMS, Data)
• Bluetooth
• Wi-Fi
• Camera
• Video Recording
• Video Playback
• Audio (Record and Playback)
• Sensors
• Flashlight

What's not working:

• VoLTE (Blame Samsung for that)
• FOD working only on highest brightness Now it's functional
• Camera HAL3 and 48MP back camera, this is due to Samsung's extension to camera HAL is not recognizable by AOSP (Again blame Samsung)
• Feel free to report any issues you may encounter with relevant logs

Installation:

• Download the latest supported Lineage OS build
• Reboot to recovery
• Wipe data, system and cache/dalvik cache
• Flash the LineageOS zip
• (Optional) Flash arm64 gapps of your choice (NikGapps or BitGapps are recommended)
• Reboot to system and enjoy!

Notes:

• GrassKernel is included with the ROM (See here)
• To use MTP as default, enable developer options and choose file transfer as default mode for usb configuration
• Only for A51 4G variant, 5G has different SoC therefore not supported

Can I flash magisk for root (ramdisk support)? Is there also lineageos recovery to flash instead of twrp? Last, is selinux enforcing or permissive?

sorry to bother, but for some reason i cant access my internal storage in any way with this rom installed (not with my phone nor my pc) i have the android 13 bootloader installed and precisely followed every step. what went wrong?

 

[Lipsum26]

Hello, is there any possibility that this rom will be ported to the official lineage operating system in the future? I am grateful for your support for our device.

hi, why are you using kernel 4.14? i thought android 13 must be use 5.15

 

[Adnan7995]

Exactly. Thats why I'm not flashing it.

 

[Royna]

hi, why are you using kernel 4.14? i thought android 13 must be use 5.15

? Does S20 have 5.15 kernel to get android 13? Minimum requirement is 4.14. 5.15 is for phones released with a13 and even it is a not a requirement, OEMs can choose 5.10.
5.15 is the latest GKI version.
Also if it can't boot then why did I post?

 

[TestUserG]

hi, why are you using kernel 4.14? i thought android 13 must be use 5.15

No, it's not correct. Even official lineage 20 (Samsung) devices have 4.14 kernel.

lineage 20-20230201 fingerprint not working

 

[testchmb]

Hi, how to install Google Phone? I tryed to install it from playstore using nikgapps, but i cant bc it says that my phone not supporting it. I also tryed to install MidThegapps but it didnt work

 

[Peam03]

13, the latest one
(Else won't boot)

How do I flash the Android 13 bootloader? The A51 4G didn't get Android 13 officially, right?
