Introduction to LMODroid:

Are you somebody who doesn't want people tracking you every day of the week? Are you wanting to be moved away from the Google ecosystem? If your answer is "Yes" then LMODroid is your solution. LMODroid is an FOSS alternative distribution of Android. And based on my usage (as well as a few others' usage) it is stable enough to use as a daily driver on the OnePlus Nord n200!

In this step-by-step guide, I am going to explain as simply as possible how to install LMODroid, while also trying to temper expectations on the application ecosystem, as by design, LMODroid is not the same thing as proprietary Android. Although, with MicroG, some of those proprietary applications can work (but that will not be covered in this guide).

Download:

*In the scenario of the links below being out of date, go to "https://get.libremobileos.com/dre" and grab the latest release and boot image.*

The first step you are going to want to take is to download the boot image named "LMODroid-X-X-XXXXXXXX-RELEASE-recovery-dre.img" with the X's being the version and date of the build respectively.

Second, you will want to download the LMODroid skin itself by downloading "LMODroid-X-X-XXXXXXXX-RELEASE-dre.zip".

Installation Process with warnings:

*! You MUST have your bootloader unlocked, or you will not be able to install LMODroid to your device! If you have not unlocked your bootloader, a Google search will pop up guides. Understand that I will not give support to those who do not listen to this warning. !*

Enable USB Debugging

Phone Configuration of USB Debugging

1. Go to Settings and find "About". Next go within the submenus and find the build number. Tap that build number 7 times. It should say something along the lines of "You are now a developer".

2. Go back to the primary System settings. Select "system" or the closest menu to it. Tap "Developer Options" and go scroll until you find "USB Debugging".

Computer configuration for USB Debugging

1. Download the SDK Platform Tools from here: https://developer.android.com/studio/releases/platform-tools . Afterwards, extract the designated sdk platform tools folder for your platform.

2. Open the extract folder until you see the adb and fastboot binaries respectively.

3. Open a terminal by right clicking in the file manager in linux (or cd'ing to it via terminal) or type "cmd" in the path bar within windows. This will open a cmd prompt.

Reboot to Fastboot and install LMODroid

1. type "./adb devices" and accept the prompt on your phone.

2. type "./adb reboot bootloader" and watch your device reboot into the bootloader.

3. type "./fastboot flash boot "drag the recovery image that you downloaded above here". (If you are in linux... try sudo or SU as default permissions don't let you use fastboot with the downloaded binaries)

4. type "./fastboot reboot recovery (again.. using sudo or SU)

*wait for your device to reboot into the recovery, it will be custom*

5. scroll down to the bottom (and select "Advanced) and then with the volume down screen to "enable ADB" and select the power button briefly to select the option.

6. Scroll back up to "apply update" and select "Apply from adb"

7. Go back into the terminal/command prompt and type "./adb sideload (drag the lmodroid skin file from above [which is lmodroid])."

8. Select "return/enter".

9. Watch your device and the terminal until the process is complete. You will see scrolling text on your device .Nothing to worry about. This is normal. You will also see your computer feeding the file to your device in the terminal. It will look like it is stuck at 47%, but it is not. Do NOT cancel the process. Wait until it says "complete" on your device and returns you to the recovery.

10. Next go to "Factory Reset", select it with the power button, and then select "Format data/factory reset". Let the reset occur.

11. Select "Reboot system now" and watch your device reboot into LMODroid. Congrats! You are all done! Now you simply need to do the set up process.

Have fun with your device!

At the request of another XDA Member, I decided to give you different recommendations of what gapps to use.

My primary choices are usually:

MindtheGapps -

The Lineage page has a mirror.

*Note*

LMODroid is meant to be a Libre version of Android, so why are you installing Google Apps? LMODroid is a slightly modified version of LineageOS. Please take a look at Lineage with Microg if you want the microg variant.

For those who want root, I recommend using Magisk from here: "https://github.com/topjohnwu/Magisk/releases/tag/v25.2". The latest version is indeed 25.2.
