The repack shines because it removes Huawei’s aggressive CPU throttling and memory management middleware. The need for unlocked bootloader (Huawei stopped providing

If your intent is purely educational (e.g., for a cybersecurity or digital forensics course):

You could write a methodology section describing how one might theoretically unpack, modify, and repack a recovery image or system image, using standard Android tools (mkbootimg, unpackbootimg, simg2img, make_ext4fs), while clearly noting:

• The need for unlocked bootloader (Huawei stopped providing unlock codes for Mate 7 in 2018).
• The high risk of bricking the device.
• That this should only be done on a device you own and in a sandboxed environment.

How repacks are typically made

1. Start with a base ROM (LineageOS/AOSP/stock deodexed build).
2. Extract or patch system and vendor blobs.
3. Integrate device‑specific kernel or kernel patches; rebuild boot.img if needed.
4. Add or swap GApps/microG, Magisk, SELinux policies, and utility apps.
5. Modify updater-binary and add custom install/remove scripts.
6. Test on the target device; iterate fixes for hardware and stability.
7. Package as ZIP and distribute (usually via XDA, GitHub, Telegram, or forums).

Step 5: The First Boot

• Reboot System. The first boot takes 5-10 minutes. Do not force restart.
• When the setup wizard appears, skip WiFi and Google login initially to avoid bootloops due to Play Services version conflicts.

🔧 ROM Details:

Part 5: Post-Installation Tweaks for the Repack

Once you boot into your new custom ROM repack, you aren't done yet. To make the Mate 7 your daily driver again, do this:

1. Disable Animation Scales: Go to Developer Options > Set Window/Transition/Animator scale to 0.5x or Off. The aging GPU will thank you.
2. Enable "Force 4x MSAA" (Also in Developer Options). This offloads some graphics rendering to the GPU, reducing CPU heat.
3. Install "Kernel Adiutor": A custom ROM repack usually includes a custom kernel. Use Adiutor to set the CPU Governor to Ondemand (not Performance) to preserve the 4100mAh battery.
4. Fix the Fingerprint: On first boot, the fingerprint might be jittery. Go to Settings > Security > Fingerprint. Delete the saved print and scan the same finger twice (as two separate entries). This solves the repack sensor lag.

🛠 Installation:

1. Reboot to TWRP
2. Wipe: Dalvik, Cache, System, Data (don’t wipe internal storage)
3. Flash CleanStock_Repack_v2.0_MT7.zip
4. (Optional) Flash Magisk if you want root
5. Reboot – first boot takes ~5–7 minutes
6. Enjoy a cleaner, faster Mate 7!
