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. 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.


Why Android 11 GO version? According to the Android 11 Go Edition Device Setup Guide, starting with Android 11 all smartphones with 1GB or 2GB of RAM must use Android Go.
Although this tablet has 3 GB of ram memory, this tablet has a technology of 8 years ago, I believe that the Android GO version can run in a responsive way with minimal lag.
In addition, some tweaks were applied to improve the overall performance for this old device.

*This rom is also compatible with SM-P601 but without 3G data network support and Phone.

Working:
> SD-card
> GPS
> S Pen
> WIFI
> Bluetooth
> Sensors
> Audio
> Screen Record
> Camera (just picture)
> IR Sensor
> MTP
> Microphone

Not Working:
> Camera (Video)

*For now there are crashes in certain apps and in certain situations. The rom is only recommended for testing and not for daily use. As the solutions are discovered , they will be applied in future builds .


How to install this ROM:
1. Install TWRP Recovery : twrp-3.5.0_9-0-lt03wifiue
From: https://dl.twrp.me/lt03wifiue/twrp-3.5.0_9-0-lt03wifiue.img.html

2. Wipe Cache, Data and System Partition

3. Install the ROM and Gapps.

Hi @DanielBR911,

I will give a try in this rom!
I tried yesteday the LuisRom, but my P600 was get TOO hot, and sound crackling on Youtube.

Did you notice some of those in your build?
Hi @edu.mariano,
You should try this rom. I'm using this ROM daily and I'm not having problem with You Tube app, video and audio works normally. Please test this Rom and let me know if you are having any problems.

Many thanks for this. I have installed and it generally seems to be working well.
  1. Glad to see audio working well as it wasn't initially in 17.1 and only recently fixed.
  2. I am using ShevT's 17.1 and he had managed to fix audio issues in 17.1 which I think were being caused by the CPU core control - after the fix the cpu cores run at almost top frequency all the time, even on the interactive governor. The same is happening in this ROM. This makes battery drain significantly higher and charging slow when the device is turned on.
  3. I installed deathly auditor - in the 17.1 rom this allowed to tweaks battery charging current, however these are not yet enabled in the 18.1 kernel.
  4. USB Midi OTG is working well.
  5. My usb soundcard is not working (but was in 17.1) - in android 10 I used the lesser audio switch app to use the tablet speakers and the usb mic to together, but this does not work in android 11 as we are supposed to be able to select usb audio inputs/outputs through volume control - this is not available in the 18.1 go.
  6. I don't think Palm rejection on the spen is working on this. ShevT had fixed this in 17.1.
  7. Some streaming apps are not available on play store (D+ and NF) although this may be because I installed magisk, but this wasn't ever an issue on 17.1.
I will continue to use and test. Thank you for sharing this.

Change your device fingerprint in MagiskProps to a certified fingerprint in order to get Netflix to show up.

Are you also noticing that Wi-Fi disconnects randomly? And there’s also no on screen nav buttons

thanks for the feedback. I think Streaming Video like Disney+ and Netflix is not available on Play store because you are using a custom rom.

One of my key apps (koala sampler) is crashing as soon as it opens. A previous test version of 18.1 by the exynos team was posted briefly for the p601, but removed as there was a memory issue causing crashes. It was said it would only be available again once this had been fixed. Have you fixed this or do you know if has been fixed in the exynos team sources?

the issues started after I tried to use my usb soundcard, so it could be related to that, but would be good to know if there is still potentially an underlying issue before doing further checking.

Seems like with this rom, the memory issue hasn’t happened. I’m about to put this rom to the test with everything that I do on a daily. Also got Netflix installed btw

I never got a chance to try the other 18.1 version - did you notice app crashes on it? Certainly the koala app is solid on 17.1 and I'll be going to back to that for now.

On ShevT’s version of 18.1, there were many app crashes cause of the memory problem. It would get to the point where the system would randomly crash and reboot. So far with this new rom, I haven’t experienced any crashes (yet). There are some features that I do want to see in the next build though. If any errors do come up I’ll pull logs. So far this rom is a step in the right direction. I installed this rom with the Opengapps Super Package.

The other problem with 17.1 was that video playback in the browser wouldn’t work unless your webview version was v89 or lower. I’m going to see if that is the case with this new rom

Today I tested several apps. So far I've had a problem with Angry Birds 2, but other Angry Birds are working fine.

    The 24.2 and 24.3 zips don’t work anymore. I believe you have to flash 24.1 as a zip then update to 24.3 after in the app itself.

    Ok, for those who want working SafetyNet and Play Store certification (for Netflix and Disney+), follow these steps (I am using Magisk 24.1 for reference, this will also work on Magisk 24.2 & 24.3):

    1. Install Rom, Gapps, and Magisk in twrp, exactly in this order.

    2. Open Magisk, make sure it says its installed. Go to the settings, enable Zygisk and DenyList. (Note: DO NOT login into your Google Account yet, we need the Play Store to get certified first)

    3. Download these 2 modules: Universal SafetyNet Fix & MagiskProps Hide Config. You'll also need to download an app called YASNAC in order to check the SafetyNet Status, and TermUX for the terminal app.

    4. Install the modules and reboot. Install YASNAC and Termux. Open YASNAC, and run the SafetyNet check. You should get the Pass result.

    5. Open Termux. Type in su. Grant Magisk root access. Type in props and hit enter.

    6. When the MagiskProps menu comes up, type 1. Then type f. A list of device manufacturers will show up. Look for Samsung and type in that number. Then a list of certified devices will come up. Look for our device (SM-P600) and type in the number that matches our device. It will ask if you want to set this as the device fingerprint. Type y. When the process is complete, type y again to reboot.

    7. Upon reboot, open the Play Store. Go to Settings, scroll down to Play Store version. It should say below that "Device is certified". You should now login into your Google account and verify this by installing either Netflix or Disney+.

    (If you don't see the device certification section yet, wait about 5-10 minutes. If it still says "Device is not certified", clear cache and app data from the Play Store. Also make sure you have the latest version of the Play Store and Google Play services. You can find those here:

    Google Play Store APKs
    Google Play services APKs (The variant for our device is 150300, 150306, 170300 or 170306: arm-v7a, Android 11+, 320 dpi)

    When finished, the results should look like this:

    Definitely down to test!
    Sure interested to test. I've not noticed crashes on 1.1 but am only using in short bursts.

    I think my magisk problems are due to having installed v23 through twrp when I installed the rom, then updating the app to v24 without updating the flashed package. If installing a new rom, I'll make sure to flash v24.
    Experimental build, some changes were made to the kernel and added support for navbar (for now the 3 keys are not being disabled). But the crash problem is still not solved 100%. Please let me know if this build got worse or better with application usage.

    Just installed this new build with a fresh copy of OpenGapps and Magisk 24. So far so good. Although, when you turn on the on screen nav buttons, the hardware keys aren’t fully disabled. You can still tap on the Menu and Back keys and they work, even with the on screen nav buttons turned on. Other than that, rom seems to be smooth so far. Working on getting the SafetyNet to pass now that Magisk 24 doesn’t have MagiskHide anymore.

    Also, don’t know if this feature is removed from Go roms, but Chat Bubbles don’t show up when I use apps like Telegram. Definitely seen this feature in other LOS 18 roms.
    Yes, GO edition removes overlays so no multi window or any overlay function. I wish there were two builds GO and regular because I use multi window.
