Understanding the Prerequisites and Risks Involved
Before embarking on this journey, it’s crucial to understand the prerequisites and potential risks associated with unlocking the bootloader and installing custom ROMs.
Data Backup: A Non-Negotiable First Step
Unlocking the bootloader will wipe all data from your device. There’s no way around this. Therefore, creating a complete backup of all your important data is paramount. This includes:
- Contacts: Sync with your Google account or export to a VCF file.
- Photos and Videos: Copy them to your computer or upload them to cloud storage services like Google Photos, OneDrive, or Dropbox.
- Apps and App Data: Use a backup tool like Titanium Backup (requires root, only applies to your current ROM) or Helium App Sync and Backup (doesn’t require root). Consider using cloud backup features offered by individual apps.
- SMS and Call Logs: Use an app like SMS Backup & Restore.
- Documents and Files: Copy them to your computer or cloud storage.
- System Settings: While difficult to fully replicate, taking screenshots of your settings can be helpful.
Battery Level: Ensuring Uninterrupted Operation
Ensure your HONOR 90 5G (REA-NX9) has at least 60% battery charge before proceeding. A sudden power loss during the unlocking or flashing process can brick your device, rendering it unusable.
USB Drivers: Essential for Communication
You’ll need the correct USB drivers installed on your computer to communicate with your device in Fastboot mode. These drivers can usually be obtained from the HONOR website or through the HiSuite software. Improperly installed or missing drivers are a common cause of issues during the process.
ADB and Fastboot: The Tools of the Trade
ADB (Android Debug Bridge) and Fastboot are command-line tools essential for interacting with your device in bootloader mode. Download and install the latest version of the Android SDK Platform Tools from the official Android Developers website. Make sure to add the ADB and Fastboot binaries to your system’s PATH environment variable for easy access.
Understanding the Risks:
- Warranty Voidance: Unlocking the bootloader typically voids your device’s warranty. Check your local warranty laws to confirm.
- Brick Risk: Incorrectly flashing a ROM or failing to follow instructions carefully can brick your device.
- Security Vulnerabilities: Custom ROMs may not always have the latest security patches. Choose reputable ROMs from established developers.
- Potential Instability: Custom ROMs can sometimes be less stable than stock ROMs and may contain bugs.
Unlocking the Bootloader on Your HONOR 90 5G (REA-NX9)
The bootloader is a security mechanism that prevents unauthorized software from being flashed onto your device. Unlocking it is a necessary step to install custom ROMs. The method for unlocking the bootloader on HONOR devices has varied over time. Here’s a general outline of the typical process, keeping in mind that HONOR may change it. We will keep this updated, but always verify on the HONOR website or forums for the latest method:
Enable Developer Options: Go to Settings > About Phone and tap the Build Number repeatedly (usually 7 times) until you see a message saying “You are now a developer!”
Enable USB Debugging and OEM Unlocking: Go to Settings > Developer Options and enable both “USB debugging” and “OEM unlocking.” The “OEM unlocking” option is crucial; if it’s missing, it might indicate that your device is locked by the carrier or that unlocking is not supported.
Request an Unlock Code: In the past, HONOR required users to request an unlock code through their website or a specific app. This process usually involved registering an account, agreeing to terms and conditions, and providing your device’s IMEI number. Check the HONOR website or forums for the current unlock code process. Note, it’s possible HONOR no longer provides unlock codes. If this is the case, then installing custom ROMs might not be possible, unless alternative methods are discovered by the community.
Boot into Fastboot Mode: Power off your device. Then, press and hold the Volume Down button and the Power button simultaneously until you see the Fastboot screen. The exact key combination may vary slightly depending on your device model, so consult your device’s documentation.
Connect to Your Computer: Connect your device to your computer using a USB cable.
Open a Command Prompt or Terminal: Open a command prompt or terminal window on your computer.
Execute the Unlock Command: Use the following command, replacing
<unlock_code>
with the unlock code you obtained (if applicable, and IF you were able to get one in step 3):fastboot oem unlock <unlock_code>
If HONOR has stopped providing unlock codes, try simply:
fastboot oem unlock
You might be prompted to confirm the unlock on your device’s screen. Use the volume buttons to navigate and the power button to select “Yes.”
Reboot: After the unlock process is complete, your device will reboot. It may take a few minutes for the first boot after unlocking.
Important Considerations:
- Official Unlock Tools: Always prioritize using official unlocking tools or methods provided by HONOR. Third-party unlocking tools can be risky and may damage your device.
- Regional Restrictions: Unlocking the bootloader may be restricted in some regions due to carrier or regulatory policies.
- HONOR stopping unlock codes: It is important to note that, like other manufacturers (OnePlus, Xiaomi and others), HONOR may have stopped providing unlock codes to maintain warranty and prevent the installation of unofficial firmware. There may not be an unlock_code to enter. This means, for the present, it may not be possible to install custom ROMS. Please check official forums and sources.
