## i Overview

This page provides a **verified and tested SPI firmware dump** for the **Nevir NVR-7400-32-HD-N** television equipped with the **17MB82-2 mainboard**. The dump file targets the memory chips at positions **U12 (25Q64FV)** and **U10 (25Q16BV)**, enabling technicians to resolve critical memory corruption issues, boot failures, and dead-set conditions using an **SP8 universal programmer**.

## ! Common Issues This Dump Resolves

- Dead TV — no power LED indicator, no standby response
- Stuck on boot logo — infinite restart loop, never reaches main menu
- Backlight active but no picture — blank screen with audio or no audio
- EEPROM corruption — erratic behavior, random settings reset
- Channel memory loss after every power cycle
- OSD menu freeze or partial display corruption
- No signal on all inputs despite functional tuner hardware
- Firmware update failure — bricked after interrupted software upgrade

## C SPI Chip Locations

Below is the SPI chip location index on the 17MB82-2 mainboard. Identify **U12** and **U10** positions before desoldering for programmer access.

## R Diagnostic & Repair Protocol

1. **Visual Inspection** — Examine the 17MB82-2 mainboard for burnt components, swollen capacitors, cracked solder joints, or physical damage near U12 and U10 areas.
2. **Power Supply Verification** — Confirm all voltage rails output correct values: 5V standby, 12V main, 3.3V logic. Use a multimeter at designated test points before proceeding.
3. **Desolder SPI Chips** — Using a hot-air rework station at 350-380 degrees Celsius, carefully remove the 25Q64FV (U12) and 25Q16BV (U10) chips. Apply flux generously to prevent pad damage.
4. **Read Original Data** — Place each chip on the SP8 programmer adapter. Attempt to read existing data and save as backup. Verify chip ID is correctly detected by the programmer software.
5. **Erase Chips** — Perform a full erase cycle on both SPI chips. Verify blank check passes before writing new data to prevent write errors.
6. **Flash Firmware Dump** — Load the downloaded BIN file into SP8 software. Write the firmware to the corresponding chip. Always match the correct file to the correct chip position (U12 or U10).
7. **Verify Write** — After flashing, run a verify operation to compare written data against the source file. A 100% match confirms successful programming.
8. **Resolder Chips** — Carefully solder each chip back to its original position on the 17MB82-2 board. Ensure correct pin 1 orientation. Clean flux residue with IPA.
9. **Test & Calibrate** — Reconnect the mainboard to the panel (VES315WNDL-01), power supply, and backlight driver. Power on and verify boot sequence, OSD menu access, channel scan, and all input ports function correctly.
