Upgrading the Huawei MediaPad T1 8.0 with a custom ROM is a popular way to extend the life of this aging tablet, which originally shipped with Android 4.3 Jelly Bean. While Huawei stopped officially providing bootloader unlock codes in 2018, independent development still exists for dedicated users. Custom ROM Options for MediaPad T1 8.0
Finding a stable custom ROM for the T1 8.0 (models S8-701u and S8-701w) can be challenging due to its age and proprietary hardware. However, several projects have historically supported this device:
CyanogenMod / LineageOS: Older unofficial builds of CyanogenMod (the predecessor to LineageOS) are the most common custom ROMs found on forums like XDA Developers.
postmarketOS: A newer community-driven project that aims to bring a Linux-based OS to older mobile devices, including the MediaPad T1 8.0 Pro.
Paranoid Android: Some community members have attempted unofficial ports of Paranoid Android to the S8-701u model. Essential Prerequisites

Availability: You won't find modern Android versions (like Android 12 or 13). Most custom builds for this device are based on Android 4.4 KitKat or early Android 5.1 Lollipop.
GSI Support: This tablet is too old for Project Treble, so you cannot use Generic System Images (GSIs).
Main Source: The most active community for this specific model remains the 4PDA forums (requires translation). 2. Essential Prerequisites
Before attempting to flash anything, you must have these basics covered:
Unlocked Bootloader: This is the biggest hurdle. Huawei officially stopped providing bootloader unlock codes years ago. You may need to use third-party tools like DC-Unlocker (paid) or specialized scripts if they are still functional for this older chipset.
Custom Recovery: You need TWRP (Team Win Recovery Project). An unofficial device tree exists for the Pro version.
Battery: Ensure your device is charged to at least 70% to prevent it from dying mid-flash. 3. Step-by-Step Process (General Guidelines) Upgrading the Huawei MediaPad T1 8
If you manage to find a compatible ROM file (usually a .zip file from XDA or 4PDA), the general process follows these steps:
Boot into Recovery: Power off the device, then hold Volume Up + Power until the logo appears.
Back Up Everything: In TWRP, go to Backup and select all partitions. This is your "safety net."
Wipe the System: Go to Wipe > Advanced Wipe and select Dalvik/ART Cache, System, Cache, and Data. Warning: This deletes all your apps and files!
Flash the ROM: Go to Install, locate your downloaded ROM zip file, and swipe to confirm.
Flash GApps: Most custom ROMs don't include Google Play. You will need to download a "Pico" or "Nano" package of OpenGApps (match your Android version and ARM architecture) and flash it immediately after the ROM. Reboot: The first boot can take 5–10 minutes. 4. Alternative: PostmarketOS
