SPI Dump Ready

## Firmware Overview

This page provides the complete **SPI memory dump** for the **12AT011-V2.0-A** main board used in the **Neo 40DLD12AT011-SF** television. The firmware file targets the **GD25Q32** flash IC and has been **tested and verified 100% working**. This resource is intended exclusively for qualified TV repair technicians performing board-level memory diagnostics and chip-level reprogramming.

**Technician Notice:** Incorrect flashing may permanently damage the main board. Ensure correct SPI chip identification and programmer configuration before writing. Proceed only if you have experience with SPI flash programming.

## SPI Flash IC Location

The **GD25Q32** (marked as 25Q32) SPI flash chip is located on the main board as indicated in the image below. Click the image to zoom and identify the exact position before desoldering.

## Known Issues This Firmware Resolves

- TV stuck on logo screen – does not proceed past the Neo boot splash
- No power response – standby LED is on but TV does not turn on
- Main board dead after lightning surge or power fluctuation
- Continuous reboot loop – TV turns on and off repeatedly
- Corrupted EEPROM / SPI data causing no display output (black screen with backlight)
- Audio present but no picture – panel initialization failure from corrupted firmware
- OSD menu freezing or TV hanging during channel scan
- Software update failure that bricked the main board
- HDMI / AV / USB ports not recognized or not functioning

## Diagnostic & Repair Protocol

**Visual Inspection:** Examine the 12AT011-V2.0-A main board for burnt components, swollen capacitors, cracked solder joints, or visible damage around the power regulation section and SPI flash area.

**Power Rail Verification:** Using a multimeter, check all voltage rails (3.3V, 5V, 12V). Confirm the SPI chip is receiving stable 3.3V supply. Verify standby voltages are present before proceeding.

**SPI Chip Identification:** Locate the **GD25Q32** chip on the board (refer to the SPI location image above). Verify the chip marking reads **25Q32** to confirm compatibility with this dump file.

**Desolder SPI Flash:** Using a hot air rework station at 350–380°C with appropriate flux, carefully desolder the GD25Q32 chip from the board. Clean the pads and chip pins with isopropyl alcohol.

**Read Original Data (Backup):** Place the chip into the **SP8 programmer** socket adapter. Read the existing firmware and save a backup before writing. This allows rollback if needed.

**Write Firmware Dump:** Load the downloaded **.bin** firmware file into the SP8 software. Select chip model **GD25Q32 / 25Q32**. Erase the chip completely, then write the new firmware. Verify after writing.

**Resolder & Test:** Resolder the programmed GD25Q32 chip back onto the main board. Reconnect the panel flex cable and power supply. Power on the TV and verify full boot, display output, and all port functionality.

## Frequently Asked Questions

What SPI chip is used on the 12AT011-V2.0-A board?

The board uses a **GD25Q32** (marked 25Q32) SPI flash memory chip. It is a 32Mbit (4MB) serial NOR flash manufactured by GigaDevice. Some board revisions may use equivalent chips such as the Winbond W25Q32 — the dump is compatible with both.

Which programmer is required for flashing?

The **SP8-A** or **SP8-B** universal programmer is recommended. It supports the GD25Q32 natively. Alternatives include the TL866II Plus or CH341A, though the SP8 provides the most reliable results for this specific chip and board combination.

Is this firmware tested and working?

Yes. This firmware dump has been extracted from a known-good **Neo 40DLD12AT011-SF** unit with panel **LTA400HM23** and verified through multiple write-read-verify cycles. It is confirmed **100% functional**.

Can I use this dump with a different panel?

This dump is calibrated for the **LTA400HM23** panel. Using it with a different panel may result in display issues such as incorrect resolution, inverted colors, or no picture. If your panel differs, LVDS and T-CON settings within the service menu may require adjustment after flashing.

Do I need to desolder the chip or can I flash in-circuit?

For the most reliable results, **desoldering is strongly recommended**. In-circuit programming (ISP) may work in some cases using a SOIC8 clip, but bus contention from other ICs on the board can cause read/write errors. Desoldering eliminates this risk.
