Why the usual Samsung advice is wrong here
Most Samsung FRP guides assume Download mode and a signed Odin payload. That is correct for a Snapdragon or Exynos flagship — and wrong for a large part of the Galaxy A range, which is built on MediaTek silicon.
A MediaTek Galaxy will not present a Download-mode interface to an Odin-style tool. Treating it as an Exynos device produces nothing but wasted attempts, and in the worst case nudges people toward flashing a mismatched firmware package.
Confirm which silicon you have
The A54 is MediaTek. If you are unsure about a specific A-series variant, the reliable signal is what FRPB detects on the USB bus: it reports the vendor ID and classifies the transport. A vendor ID of 0E8D means MediaTek; 04E8 with a download interface means a Samsung semiconductor variant.
Do not decide from the marketing name alone. A-series variants differ by region and by production batch.
Entering BROM on a Galaxy A54
Because MediaTek boots through its own Boot ROM, FRPB does not need Android, recovery, or Download mode. It needs the phone powered off and the volume keys held while the cable goes in, which puts the chipset into BROM before any Samsung firmware loads.
FRPB's detector explicitly ignores Bluetooth and virtual COM ports, so if your PC also has a headset or a com0com pair installed, they cannot be mistaken for the phone. You are waiting specifically for a MediaTek USB Port to appear.
What FRPB does with the BROM connection
Once the Boot ROM answers, FRPB performs the DA (Download Agent) handshake, reads the partition table, then formats the partitions that hold the FRP state and reboots the handset.
The console shows each of those phases as they happen. If the handshake does not answer, the phone is not genuinely in BROM — re-check the key combination rather than assuming the tool failed.
Step-by-step procedure
Follow the sequence below in order. Each step is also published as structured HowTo data, so search results can surface it as a step-by-step list.
- 1Power the Galaxy A54 off completely.
- 2Hold Volume Up + Volume Down together.
- 3Connect the USB cable while holding both buttons.
- 4Wait for Windows to detect the MediaTek USB Port (VCOM).
- 5Confirm FRPB reports the MediaTek BROM transport.
- 6Click FRP Bypass and accept the authorised-owner disclaimer.
- 7Let the DA payload injection and partition format complete.
- 8Allow the automatic reboot and check the setup wizard.
Safety, legality and when to stop
FRPB is intended strictly for authorised device owners and licensed repair professionals. You must own the device or hold explicit written permission from its owner. Using an FRP bypass tool on hardware you do not own may defeat an anti-theft control and can be illegal in your jurisdiction.
Stop and reassess if the device reports a bootloader state you did not expect, if the model or chipset FRPB detects does not match the handset in front of you, or if the operation halts mid-way. A mismatched firmware package is the single most common cause of a hard brick — abandoning an operation is always cheaper than recovering from one.
