Direct answer to the question

• I’m not “billobirillo,” and I can’t resend private links or email you proprietary firmware/software directly.
• I can, however, help you obtain the correct, safe firmware for your exact hardware and guide you through a proven recovery process.
• Key point: On these Blaupunkt/UMC sets, the firmware must match both the mainboard and the panel. A mismatch can brick the set or produce a bad image.

Detailed problem analysis

• What your identifiers tell us:
  • Product code: BS49E148BFQ0UXE12P-96167401296 (Blaupunkt/UMC 49-inch set, EU-market lineage).
  • Main board: t.m.s603.702 (often silk-marked T.MS603.702 or TP.MS603.PB702; MStar-based chassis used by UMC/Blaupunkt/Sharp-finlux family).
  • Panel: LC490DUY-SHA1 (LG Display 49" open-cell, UHD family; strict timing/LVDS mapping requirements).
  • PSU: MIP550D-240V350 (Megmeet supply used across UMC/Sharp/Blaupunkt).
  • Other stickers: A16031219-OAO1094 (board/assembly rev), 496871L-3850AFBAOKLM229 (internal label), 0025927A2A880MAC (Ethernet/Wi‑Fi MAC).
• Why this matters:
  • UMC/Blaupunkt distributes many “project builds” per board + panel + tuner + region. The correct package includes the right panel table, gamma, LVDS map, EDID/HDMI settings, and key regional options. Using a T.MS603.702 file for a different 49" panel (e.g., AUO/Samsung) commonly causes solarized/inverted video or no backlight due to wrong LED driver parameters.
  • Your “U3” reference typically points to the SPI NOR flash (commonly 32–64 Mbit/4–8 MB, e.g., Winbond W25Q32/64 or GigaDevice GD25Q32/64). If the TV is stuck in standby or boot-loops, in-circuit USB update may fail, and a direct SPI reflash is needed.

Typical symptoms that truly require firmware:

• Red-LED standby only, no logo, but all power rails present on mainboard.
• Logo loop (boots to splash, reboots).
• Corrupt OSD/fonts, missing NVRAM tables after a brownout. If your fault is “no backlight” with sound present, that’s usually LED strips/PSU, not main firmware.

Current information and trends

• For these UMC/Blaupunkt chassis, public links often expire; technicians now rely on:
  • Brand-authorized portals (UMC/Blaupunkt service).
  • Technician forums with curated SPI dumps and verified USB packages (e.g., Badcaps, Elektroda, Remont-Aud). You’ll commonly see requests tagged with the full product code plus T.MS603.702 + LC490DUY-SHA1 to guarantee a match.
• Community practice has converged on:
  • Always backing up the original SPI first to preserve HDCP keys, MAC, and calibration.
  • Preferring a USB loader if the set boots; falling back to SPI programmer if it doesn’t.
  • Verifying panel configuration via service menu once the set comes back up.

Supporting explanations and details

• How to confirm hardware on your board:
  • Locate the SPI flash (U3). Note the exact part (e.g., W25Q64FV “25Q64FV…”, GD25Q64, MX25L6406E). This determines capacity and voltage (most are 3.3 V; if you see a 1.8 V part like W25Q64JW, you need a 1.8 V adapter).
  • Measure key rails with the TV plugged in:
  • 3.3 V at SPI VCC.
  • Mainboard LDOs: 1.2 V/1.35 V core, 1.5/1.8 V DDR, 3.3 V I/O.
  • From PSU MIP550D-240V350: standby 5 V present? Main 12 V/24 V up when power-on is asserted? If 3.3 V is missing on the SPI, flashing won’t help.
• About keys and per-unit data:
  • The SPI often contains unit-unique HDCP keys, MAC address, and panel white balance. A generic dump may boot but lose DRM/Smart features or show color drift. That’s why your first action is a full backup of your current U3.

Ethical and legal aspects

• Firmware is proprietary. Redistributing dumps may violate copyright and anti-circumvention laws. I can’t email or host firmware.
• Do not publish your full SPI dump; it contains device-unique keys. Share only the necessary version strings/logs.
• Observe mains safety. The PSU and LED outputs can be hazardous. Use an isolation transformer and discharge precautions.

Practical guidelines

1. Identify and document:

   • Photos of the mainboard (showing “T.MS603.702”), panel label “LC490DUY-SHA1,” and the TV back label with the full product code you listed.
   • If the TV still boots to a menu, note the current software/build string in the About/Service menu.

2. Choose update path based on symptoms:

   • Boots to UI: Prefer a USB update.
   • Stuck in standby/logo loop: Plan for SPI reflash.

3. USB update (if the set boots):

   • Prepare a small USB stick (FAT32, ≤32 GB).
   • Place the vendor package at root. Naming varies by build (common names include “MstarUpgrade.bin”, “MSDUpgrade.bin”, “upgrade_loader.pkg”, or a model-specific .bin). Use only the package that matches T.MS603.702 + LC490DUY-SHA1 and your exact product code.
   • Trigger update via Menu > Software Update or with a forced-update key combo (commonly hold OK or VOL- on TV while applying AC power; LED will blink—procedure differs by batch).
   • Do not power off during update; allow 5–10 minutes and one auto-reboot.

4. SPI reflash (if USB path fails):

   • Tools: CH341A/TL866/RT809, chip clip or desolder + socket, 3.3 V supply, and AsProgrammer/NeoProgrammer/XGecu.
   • Steps:
     • Read the entire chip; save “backup_u3.bin” plus a second verification read; compare hashes.
     • Full erase → blank check → write verified, matching BIN → verify.
     • If verification fails repeatedly, replace the SPI with a new, same-capacity device and program off-board.
   • After first boot, immediately enter the service menu (typical codes: Menu + 1147 or Menu + 1999 on the remote; may vary) and confirm:
     • Panel selection = LC490DUY-SHA1 table.
     • LVDS map not inverted.
     • White balance/gamma present (if missing, copy from your backup when feasible).

5. Where to request the correct package (safe approach):

   • Official Blaupunkt/UMC support or regional service partners (provide BS49E148BFQ0UXE12P-96167401296, T.MS603.702, LC490DUY-SHA1).
   • Technician communities:
     • Post a request titled exactly: “Blaupunkt BS49E148BFQ0UXE12P – T.MS603.702 – LC490DUY-SHA1 – U3 SPI dump/USB pkg needed.”
     • Attach clear photos and list your SPI chip P/N. Ask for the version that preserves panel table for LC490DUY-SHA1.

6. Post-flash checks:

   • Video: no inversion/solarization, correct colors.
   • Audio and tuner region match.
   • Network MAC populated (matches your label 0025927A2A880MAC or the set’s printed MAC).
   • HDMI HDCP works (try a protected stream).
   • If only image is wrong but set boots: try alternate configuration via service menu before assuming a bad dump.

7. If symptoms persist after a known-good firmware:

   • Suspect hardware:
     • BGA under the SoC (intermittent boot; warm the SoC gently—only as a diagnostic).
     • Faulty DDR.
     • PSU/backlight (MIP550D LED output sag; test LED strings with a current-limited LED tester).
     • T‑Con or panel shorts (check VGL/VGH/Vcom on T‑Con; panel shorts will pull down rails and cause boot aborts).

Possible disclaimers or additional notes

• Not all dumps are interchangeable; even within T.MS603.702, tuner and feature variants differ. Always prefer a package tagged for your exact product code.
• Some “fixed” images online strip HDCP keys. Expect streaming/HDMI handshake issues in that case.
• Forced USB key combos differ by remote/control board variant; if one method fails, try the alternative sequence or a different USB stick brand/size.

Suggestions for further research

• Search terms to use when requesting firmware:
  • “T.MS603.702 LC490DUY-SHA1 SPI dump”
  • “Blaupunkt BS49E148BFQ0UXE12P firmware”
  • “UMC 49 LC490DUY SHA1 usb update”
• Forums with active dumps for UMC/Blaupunkt chassis: Badcaps, Elektroda, Remont-Aud (requires registration). Post your photos and the full product code as above.
• Consider a low-cost logic analyzer/UART adapter to capture boot logs at 115200 8N1; logs quickly distinguish NAND/SPI corruption from DRAM/SoC faults.

Brief summary

• I can’t resend a private link or send you firmware directly, but I can help you get the right image safely.
• Your set requires a firmware matching T.MS603.702 + LC490DUY-SHA1 and your exact product code. Back up U3 first, then use a USB update if possible; otherwise, reflash the SPI with a verified dump.
• If a correct firmware doesn’t resolve the fault, proceed with hardware diagnostics (rails, LEDs, BGA, T‑Con).

If you share:

• Exact symptom progression (standby only, logo loop, no backlight, etc.),
• A photo of the mainboard label and the SPI chip marking, I’ll tailor the next steps (including the safest forced-USB procedure for your board and a verification checklist).
