Samsung: FRP, KG, MDM, Download Mode and Odin
Samsung has its own modes and its own protections: FRP, KG Locked and MDM. They look alike but mean different things, which affects both the tool and the order of work. This page gathers guides for the A05, A15, A34 and A54 and general explanations of each status.
Statuses and protections
Before choosing a tool, work out what is actually locking the device. KG Locked and MDM are not the same as ordinary FRP, and each has its own guide.
Where to start
- General choice: FRP on Samsung — which tool to pick.
- Connection mode: how to enter Download Mode.
- Model breakdowns: A05 and A05s, A15, A54 and A34, the A series overall.
Firmware and bootloader
If Odin shows an error, see the causes of Odin Fail. Bootloader questions are covered in the OEM unlocking guide. Check a model in Android Multi Tool with the Samsung model list. Our Samsung FRP page summarises the main routes.

FAQ
What is KG Locked on Samsung?
It is a Knox Guard status — a protection used by sellers of devices sold on instalments. It differs from FRP and needs a separate approach.
How does MDM differ from KG?
MDM means the device is managed by an organisation; KG is a protection tied to remote locking. Signs and differences are explained in separate guides.
How do I enter Download Mode?
The key combination depends on the model: usually you hold the volume keys while connecting a powered-off phone to a PC. Exact steps are in the Download Mode guide.
