Note: Performance will not be as snappy as a 2024 tablet, but for basic browsing, media consumption, and calling, Lollipop runs surprisingly well on the Kirin 910 chipset with 2GB RAM. Copy the entire dload folder to the root

4. Post-Installation Configuration

4.1 Initial Setup

• Skip Google sign-in initially to reduce lag.
• Enable Developer options again (tap build number 7 times).
• Go to Developer options → set Window animation scale, Transition animation scale, Animator duration scale to 0.5x or off.

Copy the entire dload folder to the root directory of your microSD card. Start the Update: Power off your MediaPad. Insert the microSD card.

• Huawei MediaPad X1 7.0 (fully charged – at least 70% battery).
• A Windows PC or Laptop (macOS/Linux works too, but Windows is easiest for drivers).
• Original USB cable (a high-quality data sync cable).
• MicroSD card (at least 4GB, formatted to FAT32). You will copy ROM files here.
• Huawei USB drivers – Download from Huawei’s official support site or use HiSuite.
• ADB & Fastboot tools – Download Platform Tools from Google (or Minimal ADB & Fastboot).
• Lollipop custom ROM (ZIP file) – We’ll discuss which one below.
• Google Apps (GApps) – For Play Store and Google services (choose ARM → Android 5.1 → pico or nano).
• TWRP recovery image (specific for MediaPad X1 7D-503L/501u).

5.3 No IMEI / No Cellular Signal

• Cause: Lost modem partition.
• Fix: Restore modem backup from Nandroid (restore only “Modem” or “EFS” partition) or reflash stock firmware via Huawei’s dload method.

• Use Huawei HiSuite to backup contacts, messages, call logs, and apps.
• Manually copy photos, videos, and documents to your PC or cloud storage.
• Use Titanium Backup (if rooted) – but since you’re on stock, HiSuite is fine.
