[Android] Installing LineageOS on a Motorola Moto G100

 , , , , , , ,

Just installed LineageOS on a used Moto G100. Following are a few notes I made while working through the excellent installation guide.

Two settings must be enabled in the Developer options on your device before you start:

  • Developer options → Enable USB-Debugging
  • Developer options → Enable OEM unlocking

Otherwise, you will encounter the same error as I did when unlocking the bootloader.

adb reboot bootloader
fastboot devices
fastboot oem get_unlock_data
fastboot oem unlock UNIQUE_KEY

After entering the UNIQUE_KEY, select “Unlock Bootloader” on your phone with the volume down button and confirm with the power button.

The next point that confused me for a second was this:

But you just have to use the volume buttons and select recovery on the smartphone screen from the menu you’re in. I just didn’t realize it was a menu at first…

All in all, everything worked without any problems and took maybe 30 minutes in total.

[DerpFest] Xiaomi Pad 5 (nabu)

 , , , , , ,

I recently bought a used Xiaomi Pad 5 for 139.99€ from homezesting.com. It arrived in perfect condition.
The latest official Android version by Xiaomi is Android 13 with MIUI 14.0.5. This is kinda old, and I directly ran into an issue due to the old webview version in combination with the Home Assistant app (see here).

I therefore looked for a custom ROM and the first ROM I found for this device was DerpFest. I’ve never used it before, but flashing it shouldn’t be too different from other ROMs.
There are not much information on their website, but I found everything needed to know in their related telegram group: https://t.me/c/2284318430/8189

Unlocking the bootloader for Xiaomi devices can be annoying, but turned out, the bootloader of my purchased Pad 5 was already unlocked. Great!
(Update 10.02.2025: I asked the customer support and apparently they already sell all devices unlocked. Good to know!)

To make my life even simpler, I used the Auto-Installer shell script to install DerpFest 15. Unfortunately, it was running into an error, but it was easy to fix. (Seems like there is already a fixed version when downloading from GitHub here).

# make it executable
sudo chmod +x install_derpfest_linux.sh         

# start script
./install_derpfest_linux.sh  
# resulted in the error: /bin/bash^M: bad interpreter

# fix
sudo apt-get install dos2unix
dos2unix install_derpfest_linux.sh   
./install_derpfest_linux.sh

Then the script ran without any issues.

When starting the device the first time, I skipped the Google Login step, so I wasn’t able to use the Play Store. But since not even a web browser is installed by default (which I think is really great to not be bloated from the beginning :-), I had to enable USB-Debugging mode and sideload F-Droid to install basic apps like a file explorer and browser.

adb install F-Droid.apk

The Tablet is running super smooth and so far I could not find any issues! 🙂
