So the OEMs start off by locking the bootloader on their devices, but they still leave a slight window of opportunity for the tech enthusiasts. This way they could then unlock the device’s bootloader and install tons of custom binaires. These may include installing custom ROMs, installing a custom recovery like TWRP or rooting the device via Magisk. Once rooted, you gain access to the system partition and could install Magisk Modules, Xposed Framework, Substratum Themes and the likes. But this journey is more easier said than done. To begin with, OEMs like Nokia and Huawei have made it extremely difficult to carry out bootloader unlocking. Along the same lines, Xiaomi has made matter worse for the tech enthusiasts by blocking the EDL mode for the normal users. Likewise, if you have successfully unlocked the bootloader and rooted your device, you will have to settle for some trade-offs. These trade-offs comes in place all thanks to Google’s SafetyNet Test. If your device fails this test (which all rooted devices will, under normal circumstances), then some of the deivce’s functionality will be limited. As a result, it becomes all the more important to fix the ctsProfile mismatch error on your rooted Android device. And if you are looking to do the same on your device, then this guide shall help you out.

What are ctsProfile and SafetyNet?
The SafetyNet is a security mechanism implemented by Goolge on all Android devices whose major task is to check whether your device passes the Compatibility Test Suite or not. So how would your device pass this CTS? Well, its simple- if there is no system level modification on your device, then your CTS profile’s integrity is maintained. As a result, SafetyNet will give out the True message. However, if you perform any custom development tweak that make changes to the system partition, the CTS will straightaway fail. In other words, rooting your device will lead to the failure of CTS. And hence SafetyNet test well give out the False result under both the ctsProfile and basicIntegrity checks.
SafetyNet Test Failed: The Consequences
So what exactly are the conseqneuces of failing this test? In other words, why do we even need to fix the ctsProfile Mismatch Error on our rooted Android device?
