Title: Feasibility Analysis and Implementation Guide for Android 5.0 Lollipop Updates on the Huawei MediaPad X1 7.0
Abstract
This technical paper examines the upgrade process for the Huawei MediaPad X1 7.0 (Model IDs: S7-701u, S7-701w) from the native Android 4.2 Jelly Bean operating system to Android 5.0/5.1 Lollipop. The paper analyzes the hardware constraints of the HiSilicon Kirin 910 chipset, evaluates the availability of official firmware, and outlines the procedural requirements for installing third-party Custom ROMs. Emphasis is placed on the necessity of bootloader unlocking and custom recovery installation due to the cessation of official manufacturer support.
The Huawei MediaPad X1 7.0 Lollipop install is not for the faint of heart, but for enthusiasts, it’s a rewarding project. While Huawei abandoned this device years ago, the custom ROM community has kept it alive. With Android 5.1.1, you gain modern app support, improved battery life, and a far more polished interface.
However, be realistic: The hardware is from 2014. Even with Lollipop, you won’t run heavy games or the latest social media apps smoothly. But as a secondary device for reading, video streaming, and light browsing, the MediaPad X1 remains surprisingly capable.
Final checklist before you start:
If you succeed, you’ll own one of the few MediaPad X1 tablets running Lollipop—a true testament to the power of open-source software.

Important reality check:
Huawei never released an official Android Lollipop update for the MediaPad X1. The device shipped with Android 4.2.2 (Jelly Bean) and its last official firmware was Android 4.4.2 (KitKat) with EMUI 2.0/3.0.
If you see “Lollipop 5.0” mentioned online for this tablet, it refers to unofficial custom ROMs (e.g., CyanogenMod 12.1 or AOSP-based builds).
Once Android 5.1.1 Lollipop boots:
Huawei devices before 2018 allowed bootloader unlocking via official codes. Unfortunately, Huawei closed the official bootloader unlock service in 2018. However, for the MediaPad X1, there are still methods:
Method 1: DC-Unlocker (Paid, ~4€)
Method 2: Unofficial tools (Use with caution)
Once you have the unlock code (16–20 digits):
adb reboot bootloader
fastboot oem unlock <YOUR_UNLOCK_CODE>
Your tablet will reboot and factory reset. Bootloader is now unlocked.

Installing Android Lollipop on the Huawei MediaPad X1 7.0 can refresh the device with modern UI and features, but success depends on using the correct firmware or a stable custom ROM tailored to the exact model. Users should back up data, ensure correct drivers and tools, and weigh benefits against warranty and stability risks. When performed carefully—especially by following device-specific community guides—an upgrade can be achieved, but cautious preparation and readiness to troubleshoot are essential.
Updating the Huawei MediaPad X1 7.0 (available in variants such as
) to Android 5.x Lollipop is possible but often requires moving beyond standard Over-the-Air (OTA) updates. While the device originally shipped with Android 4.2 Jelly Bean, later official and community-based updates brought it to Android 4.4.2 KitKat and eventually Android 5.0/5.1 Lollipop. Official Update Method (OTA)
The easiest way to check for an available Lollipop update is through the system settings. Navigate to Settings: Open the Settings app.
System Updates: Scroll to the bottom and select System & updates (or About tablet > System update on older EMUI versions).
Check for Updates: Tap Check for Updates. If a Lollipop-based version is available for your specific region and model (e.g., EMUI 3.x), follow the on-screen instructions to download and install. Manual Update Method (dload/SD Card)
If the OTA update does not appear, you can manually flash official firmware using an SD card. Conclusion: Breathe New Life Into an Old Warrior
Identify Model: Check the side of the box or Settings > About tablet for your exact model: (3G), (4G), or (International).
Download Firmware: Locate the official Lollipop firmware (often labeled as Android 5.0 or 5.1.1) from Huawei firmware archives or community forums like XDA.
Prepare SD Card: Create a folder named dload in the root directory of a blank SD card (at least 2GB free).
Copy File: Extract the downloaded firmware and copy the UPDATE.APP file into the dload folder. Installation: Power off the device. Insert the SD card.
Press and hold Volume Up + Volume Down + Power buttons simultaneously. The device should detect the update file and start the installation automatically. Custom ROM Method (Advanced)
For those looking to install unofficial versions (like CyanogenMod/LineageOS ports), the process involves unlocking the bootloader and using a custom recovery like TWRP.
The Huawei MediaPad X1 7.0 originally launched with Android 4.2 (Jelly Bean) and later received an official update to Android 5.0 (Lollipop) via Huawei's EMUI 3.0 or 3.1 interface. Because this is an older device, you typically have two ways to install the update: an automatic over-the-air (OTA) update or a manual "dload" installation. Method 1: Automatic Over-the-Air (OTA) Update
This is the easiest method if your device is still connected to official servers.
Backup Data: Ensure all your photos and files are backed up.
Charge Battery: Your tablet should have at least 50% battery or be plugged into a charger. Check for Update: Go to Settings > System updates. Tap Check for updates.
