Install Lynnrin-AOSP on hiphi

Unlocking the bootloader

1. Connect the device to your PC via USB.
2. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:

   adb reboot bootloader
   

   You can also boot into fastboot mode via a key combination:

   • With the device powered off, hold Volume Down + Power.
3. Once the device is in fastboot mode, verify your PC finds it by typing:

   fastboot devices
   

   If you don’t get any output or an error:

   • on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
   • on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable and port!

4. Follow the instructions at Motorola Support to unlock your bootloader.

   info_outline

   Note: If your device is not supported by the Motorola Bootloader Unlock website, you may be able to use an alternative bootloader unlock method like SunShine, though they only support some devices/firmwares.
5. Since the device resets completely, you will need to re-enable USB debugging to continue.

Flashing additional partitions

1. Download the following files from the directory named with the latest date here.
   • vendor_boot.img
2. Power off the device, and boot it into bootloader mode:
   • With the device powered off, hold Volume Down + Power.
3. Flash the downloaded image files to your device by typing (replace <...> with the actual filenames!):

   fastboot flash vendor_boot <vendor_boot>.img
   

Installing a custom recovery using fastboot

1. Download Recovery.
   warning

   Important: Other recoveries may not work for installation or updates. We strongly recommend to use the one linked above!
2. Connect your device to your PC via USB if it isn’t already.
3. If your device isn’t already in fastboot mode, on the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:

   adb reboot bootloader
   

   You can also boot into fastboot mode via a key combination:

   • With the device powered off, hold Volume Down + Power.
4. Once the device is in fastboot mode, verify your PC finds it by typing:

   fastboot devices
   

   If you don’t get any output or an error:

   • on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
   • on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable and port!
   check

   Tip: Some devices have buggy USB support while in bootloader mode, if you see fastboot hanging with no output when using commands such as fastboot getvar ..., fastboot boot ..., fastboot flash ... you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub.
5. Flash recovery onto your device (replace <recovery_filename> with the actual filename!):

   fastboot flash recovery <recovery_filename>.img
   

6. Now reboot into recovery to verify the installation.
   • Use the menu to navigate to and to select the Recovery option.

Ensuring all firmware partitions are consistent

In some cases, the inactive slot can be unpopulated or contain much older firmware than the active slot, leading to various issues including a potential hard-brick. We can ensure none of that will happen by copying the contents of the active slot to the inactive slot.

To do this, sideload the copy-partitions-20220613-signed.zip package by doing the following:

1. Download the copy-partitions-20220613-signed.zip file from here. It should have a MD5 sum of 79f2f860830f023b7030c29bfbea7737 or a SHA-256 sum of 92f03b54dc029e9ca2d68858c14b649974838d73fdb006f9a07a503f2eddd2cd.
2. Sideload the copy-partitions-20220613-signed.zip package:
   • On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
   • On the host machine, sideload the package using: adb sideload copy-partitions-20220613-signed.zip
   info_outline

   Note: The copy-partitions script was created by LineageOS developer erfanoabdi and filipepferraz
3. Now reboot to recovery by tapping “Advanced”, then “Reboot to recovery”.

Installing Lynnrin-AOSP from recovery

1. Download the Lynnrin-AOSP installation package that you would like to install.
2. If you are not in recovery, reboot into recovery:
   • With the device powered off, hold Volume Down + Power, then select “Recovery mode” using Volume keys.
3. Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one).
4. Return to the main menu.
5. Sideload the Lynnrin-AOSP.zip package:
   • On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
   • On the host machine, sideload the package using: adb sideload filename.zip.
     check

     Tip: Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report adb: failed to read command: Success. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.

6. (Optionally): If you want to install any add-ons, click Advanced, then Reboot to Recovery, then when your device reboots, click Apply Update, then Apply from ADB, then adb sideload filename.zip those packages in sequence.

   info_outline

   Note: Add-ons aren’t signed with LineageOS’s official key, and therefore when they are sideloaded, Lineage Recovery will present a screen that says Signature verification failed, this is expected, please click Continue.
   info_outline

   Note: Google Apps already included on Lynnrin-AOSP, no need install Google Apps add-on any more
7. Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
