There are two primary methods depending on the age of your device.

| Problem | Likely Cause | Solution | |---------|--------------|----------| | Boot loop after flash | Wrong DDR timing (RK) | Reflash with "Loader" mode, not Mask ROM. | | Touchscreen not working | Missing .conf file | Copy correct gt9xx.conf or ft5x_ts.conf to /vendor/etc/. | | WiFi/BT broken | Driver mismatch (e.g., RTL8723 vs AP6212) | Extract vendor.img from stock backup, flash only that partition. | | Stuck at T3L logo | Corrupted userdata | Enter recovery (Power + Vol+), wipe data/factory reset. |

The most common reason. A bad OTA update, corrupted cache, or a faulty power-off sequence can cause the T3L to get stuck on the boot logo. Flashing stock firmware is the only cure.
