[ROM][13][UNOFFICIAL][STABLE] LineageOS 20

[rttxda]

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.​

Installation guide:

Spoiler: Using Lineage recovery

1. Recommended Samsung firmware version is A705FNXXU5DVK6, but it will work on slightly older versions too.​

Make sure that the bootloader is unlocked.​

--

2. Boot the phone into download mode. Flash Lineage recovery through AP button in Odin.​

Download here.​

Note: Use TWRP at your own risk! It does not properly support new A13 roms with the latest changes.
Use Lineage recovery for the best experience, otherwise don't complain if your phone bootloops.
--

3. Boot into recovery (Vol+ and Power while USB is plugged into PC)​

Note: Samsung's OneUI wipes the custom recovery partition and possibly vbmeta while booting so try not to reboot into Android.
--

4. Format data and system in the recovery​

--

5. Flash the rom in "Apply update" menu.​

There are 2 ways to install:

• On the phone: Copy the zip to a FAT32-formatted microSD card and install it in recovery.
• With a PC: Use Minimal ADB on Windows. Open "cmd-here" and type

  adb sideload <rom-file>

  where <rom-file> is the filename (drag-and-drop the zip file into cmd window).

--

6. (Optional) Flash add-ons such as Google apps or Magisk in the same way that you flashed the rom.​

We now have a working ramdisk so newest Magisk works fine ^^
--

7. Reboot and enjoy ​

Downloads:​

Screen off fingerprint not working even after enabling it from settings. However, to lineageos 19.1, it was working as expected.

 

[rttxda]

Will look into that, thanks for reporting. You can use DT2W or raise to wake in the meantime

Edit: fixed as of 20221126

 

[Rummyy2003]

Still downloading hope no sleep of death

 

[JDMP04]

all good on the a70 (sm-a705mn) for now
thanks for the rom

 

[xandar_null]

Great work as always, thanks a lot

 

[rttxda]

New update is now available, with Screen off FOD fixed (make sure you enable it in settings). You might also find that Always on display is turned on by default, it can be turned off with a quick settings tile. You also can update through settings app on the phone.

For OTA updates I recommend Lineage recovery and, if you need root, Lygisk. Don't report bugs with updates if you use Magisk.

Is volte working in this rom?

Don't expect VoLTE on _any_ rom for a samsung phone, there is no implementation in AOSP. Official devices lack it too. No developer has bothered to do volte so far (and probably won't unless there's a good reason). Other than that, we're pretty much as bugless as we can get currently.

Thanks, due to needing Volte for calls and texts, now that 3g is shut down, looks like im stuck using stock.

Apart from that, only thing you could do is use OneUI mods.. volte might happen one day if someone takes the time to reverse engineer it but so far we're out of luck. This is a problem on every samsung device on AOSP, and with other makes, YMMV.

It modded with magisk and safety net pass. Debloated and such. I really like los though.

 

[rttxda]

Personally I'd say los is a great experience as long as 3G calls are not a problem, I use it on my daily phone which has no volte either, but at least is maintained officially
(Also in many countries 3G is shut down before 2G so I'm pretty sure 2G can still be used in those)

How to make dual sim work?

 

[rttxda]

Works out of the box if you haven't messed with the efs partition and did a clean flash. You can also try 19.1 just in case.

 

[Aidin.rk]

vendor needs to update

 

[rttxda]

Why? Even the security patch wasn't bumped. It's not so urgent, it was literally released today.

 

[DiEGo7SiLVa]

muito obrigado, A70 é muito mais rápido comparado ao LOS 19.1, você tem uma recomendação de kernel?

 

[rttxda]

thanks a lot, A70 is much faster compared to LOS 19.1, do you have a kernel recommendation?

Use the lineage kernel, it's most stable and has good performance too. Older "mod" kernels will not work with android 13

 

[raph_200314]

My phone can't detect sim 2 on OTA builds but in the older builds it does. A705MN/DS.
