Dead boot repair for Exynos is flawless. | | Xiaomi (Mi, Redmi, POCO) | Very Good | ISP pinouts known. Requires EDL authorization cable sometimes. | | Huawei (Kirin 7xx, 9xx) | Good | Works pre-HarmonyOS.

Do not use for iPhones. | | Motorola/LG | Moderate | Works, but requires specific resistor values on ISP lines. |
