Flashing Error 0x07030084

[steveh64]

Drive: LG BU40N A1, MT1959, FR07 (2018)

Operating system: Ubuntu Linux, direct SATA

Firmware image: DE_LG BU40N 1.00

Tool: MakeMKV 1.17.7, rawflash main

Error: DEBUG: Code 117637252

Result: Drive remains on FR07

What causes this flashing error, and is there a verified Linux procedure for this FR07 drive?

go to 1.03mk first then 1.00
thats what the guide says to do....

Thanks for confirming the FR07 → 1.03MK → 1.00 sequence.

I attempted the first stage using MakeMKV 1.17.7 on Ubuntu:

```
makemkvcon f -d dev_21:0 -f /home/arm/bu40n-update/firmware/sdf-current.bin rawflash enc -i /home/arm/bu40n-update/firmware/BU40N_1.03.bin
```

It returned:

```
Reading input file /home/arm/bu40n-update/firmware/BU40N_1.03.bin
Flashing flags = 0x0
Sending image in encrypted format
DEBUG: Code 117637252
```

The drive still reports FR07 and is functioning.

Should the first-stage 1.03MK flash use `rawflash main` without `enc` instead? Or is another procedure required for FR07 on a direct-SATA BU40N?

I'd appreciate confirmation before another flashing attempt.

no enc

Thanks for confirming that I need to flash my BU40N from FR07 → 1.03MK → 1.00.

I've attempted the first-stage 1.03MK flash using MakeMKV 1.17.7 on Ubuntu Linux, but both methods failed.

**Drive information:**
- Model: HL-DT-ST BD-RE BU40N
- Current firmware: FR07
- Platform: MT1959
- Bootloader: BU5
- Connection: Direct SATA (not USB)
- MakeMKV: 1.17.7
- Firmware tool: MTK19xx v1.30

**Attempt 1 — With encryption:**
`rawflash enc -i BU40N_1.03.bin`

**Attempt 2 — Without encryption:**
`rawflash main -i BU40N_1.03.bin`

Both returned the same error:

```
DEBUG: Code 117637252
```

Hexadecimal: `0x07030084`

The drive still reports firmware FR07 and remains accessible. Linux has not reported corresponding drive errors.

**My questions:**

1. What does error `0x07030084` mean for this drive?
2. Does FR07 require a special flashing method or an intermediate firmware version?
3. Is there a working Linux command for flashing this particular BU40N, or is a Windows-based flashing utility required?
4. Is there anything else I should check before attempting another flash?

I'd appreciate the exact recommended procedure, since I don't want to risk bricking the drive by experimenting with flashing flags.
