Install Custom ROM

This method is mainly aimed at Motorola Moto G32/G42/G52/G200 devices

Step 1: Download Motorola USB Drivers

1. Open your web browser and download Motorola USB Drivers from official download page:

   Motorola USB Drivers

2. Click on “Download” for your operating system.

3. Open the downloaded file and then install it.

Note

GNU/Linux based operating systems already contain usb drivers. It is not necessary to perform an installation on these systems.

Step 2: Download Recovery/Kernel

Custom recoveries are installed in the boot.img partition of the device, but for this to load correctly it must be compatible with the vendor_boot.img and dtbo.img partitions, so we need to install all three partitions to have a functional recovery.

• Directoryfiles

  • boot.img (This is where the kernel and recovery are stored)
  • vendor_boot.img (This is where the kernel modules are stored.)
  • dtbo.img (Here is the configuration of the modules)

Recovery G32

Recovery G42

Recovery G52

Recovery G200

Step 3: Install Recovery/Kernel

To perform the installation you must have ADB/Fastboot installed on your pc. You can refer to the following guide to perform the installation. Install ADB and Fastboot.

1. Enable the “Developer options” on your system and activate “USB debugging”.

2. Connect your device via USB, if you get a message saying “Allow USB debugging?” click “Allow”.

3. Reboot your device to bootloader

   adb reboot bootloader

4. Install the recovery with the following commands.

   fastboot flash boot boot.img
   fastboot flash vendor_boot vendor_boot.img
   fastboot flash dtbo dtbo.img

5. Reboot your device to recovery

   fastboot reboot recovery

Setp 4: Install Custom ROM

Tip

This step is only done if you are on Stock ROM and want to install a Custom ROM. Install the copy-partitions-20220613-signed.zip file. You can download the file from Here. Select “Apply Update” and then use the following command:

   adb sideload copy-partitions-20220613-signed.zip

Finally select “Advanced” and then “Reboot to recovery”.

1. Click on “Apply update” and then “Apply from ADB”:

   adb sideload rom.zip

   Note

   If the process stalls or ends at 47%, do not worry, it is normal.

   Note

   When it appears in carter it says:

   Signature validation failed Install anyway?

   Click Yes and wait for the installation to finish.

2. Select “Advanced” and then “Reboot to recovery”.

   Note

   Sometimes you may see a message saying:

   To install additional packages, it is necessary to restart the recovery first do you want to restart in recovery mode?

   Select Yes.

3. (Optional) If your rom is vanilla and you want to install gapps, you can install it the same way as the custom rom.

   adb sideload gapps.zip

   Then reboot to recovery.

4. Finally select “Factory reset” and then “Format data/factory reset” and reboot the system with “Reboot system now”.

Note

At the end of the installation of the Custom ROM the recovery will be replaced by the recovery of the installed Custom ROM.

Extra: Mistakes you may face:

Downgrade SPL error

Danger

ERROR: recovery: Current SPL: XXXX-XX-XX Target SPL: XXXX-XX-XX this is considered a downgrade
ERROR: recovery: Denying OTA because it’s SPL downgrade

It happens when you try to install a rom with a date prior to that indicated by the recovery.
How can I know what is the date of my recovery?
Example 1: The date of this recovery is (20241019) Year: 2024 , Month: 10, Day: 19.
Example 2: The date of this recovery is 2412031921 Year: 2024 , Month: 12, Day: 03, Hour: 19, Minutes: 21.\

Solution

You should look for a recovery with an earlier date than the Custom ROM you are trying to install or use an alternative recovery such as TWRP or OrangeFox.
