Huawei T1-701u Custom Rom [work] Online

Do not look for Android 10 or 11 ROMs for this device. The hardware limitations mean the maximum stable functional Android version is usually Android 5.1 Lollipop or, at a stretch, Android 6.0 Marshmallow (via CyanogenMod 13). Any "Lollipop 5.1" ROM is considered the sweet spot for this tablet.
