FAQ
TL;DR: Need firmware for F&U FL28101 with HK-T.RT2957P61 and ST2751A01-4? The SPI is 25Q64, and “EEPROM / FLASH: 25Q64.” Cross‑brand dumps caused image issues. [Elektroda, tera610, post #16705630]
Why it matters: This FAQ helps techs quickly identify a compatible dump, avoid bad flashes, and program the 25Q64 safely.
Quick Facts
- Mainboard: HK-T.RT2957P61 for F&U FL28101; pairing matters for picture mapping. [Elektroda, tera610, post #16705630]
- Panel: ST2751A01-4 confirmed for the discussed dump context. [Elektroda, fadili, post #17635368]
- SPI flash device: 25Q64 (serial EEPROM/flash) used on this board. [Elektroda, tera610, post #16705630]
- Using dumps from MANTA/DEX/ARIELLI/NEVIR on other panels produced reversed image. [Elektroda, tera610, post #16705630]
- A shared Akai dump was later stated “not corrupted.” [Elektroda, fadili, post #17633481]
Where can I get a working firmware dump for F&U FL28101 (HK-T.RT2957P61 + ST2751A01-4)?
In the thread, a contributor shared an Akai-origin dump and later affirmed it was “not corrupted.” Users should match board and panel before flashing. Request the file from the sharer or thread maintainers. Verify panel ST2751A01-4 and board HK-T.RT2957P61 to avoid mapping errors. “Match panel first, then flash.” [Elektroda, fadili, post #17633481]
Does firmware from MANTA, DEX, ARIELLI, or NEVIR work on this exact panel?
No. The OP reported that dumps from those brands on the same board but a different panel caused inverted image. Panel timing tables differ across panels, even on the same mainboard. Always flash a dump matched to ST2751A01-4 to prevent picture issues. [Elektroda, tera610, post #16705630]
What flash chip does the HK-T.RT2957P61 use on this TV?
It uses a 25Q64 SPI flash device for the main firmware storage. Locate it near the tuner or CPU and program it in-circuit or off-board using a clip or socket. Label on the chip will show 25Q64. [Elektroda, tera610, post #16705630]
Is the Akai BIN really corrupt?
A user initially claimed corruption, but the sharer later stated, “OK.jet is not corrupted.” If you get errors, re-download, verify checksum, or try a different programmer. Ensure voltage and clip contact are correct before concluding corruption. [Elektroda, fadili, post #17633481]
Which panel and board does that shared BIN target?
The contributor specified the pairing: HK-T.RT2957P61 board with panel ST2751A01-4. Flashing it on other panels may cause image faults or no picture. “HK-T.RT2957P61 Panel: ST2751A01-4.” [Elektroda, fadili, post #17635368]
I see no image after flashing a DEX dump—what happened?
A user reported no image with a DEX TV SPI file. This indicates panel-table mismatch. Reflash with a dump confirmed for ST2751A01-4 on HK-T.RT2957P61. Do not rely on brand-only matching; panel ID is critical. [Elektroda, tera610, post #17358580]
Did anyone have the original 25Q64 dump from the F&U set?
No. The OP noted the original chip did not read, so an original F&U dump was unavailable. This is a common failure scenario when the flash is damaged or locked. Plan to source a known-good matched dump instead. [Elektroda, tera610, post #17358580]
How do I program the 25Q64 on HK-T.RT2957P61?
- Identify and remove power; clip to the 25Q64 SPI flash or desolder it.
- Write the matched BIN for ST2751A01-4 using your programmer.
- Verify, reinstall, and test image orientation and backlight. If wrong, re-flash a panel-matched dump. [Elektroda, tera610, post #16705630]
Why does panel matching matter so much on this board?
Firmware contains panel timing and orientation tables. Using a dump from a different panel can flip the picture or kill the image. The thread examples show inverted or absent image when mismatched. Always align board, panel, and dump. [Elektroda, tera610, post #16705630]
Is the string “arielli2015062288fhd0658” the right file for this TV?
A user referenced that filename while discussing dumps. It was not confirmed as correct for F&U FL28101 with ST2751A01-4. Avoid flashing unnamed or mismatched files without confirmed panel compatibility. [Elektroda, lagoniko, post #17086712]
What is an EEPROM/SPI flash “dump” in this context?
A dump is a binary copy of the TV’s firmware stored in the 25Q64 SPI flash. Technicians program this file to restore software, display timings, and settings tied to the panel. The OP explicitly requested a 25Q64 dump. [Elektroda, mailo, post #17086759]
What if the flash chip won’t read or verify?
The OP encountered a chip that wouldn’t read, meaning no original content was retrievable. Replace the 25Q64 and program a verified, panel-matched BIN. Poor clip contact or Vcc levels can also cause read failures. [Elektroda, tera610, post #17358580]
Someone asked if the 25Q64 is on the PCB—where is it?
Yes, it’s on the mainboard near the SoC. The user’s question confirms they were locating it on the PCB. Look for an 8‑pin SOIC labeled 25Q64. Use a clip or desolder for reliable programming. [Elektroda, lagoniko, post #17086833]
How do I avoid inverted image after flashing?
Use a dump verified for ST2751A01-4. The OP reported reversed image when using dumps from other brands with different panels, even on the same board. Panel match prevents orientation and timing mismatches. [Elektroda, tera610, post #16705630]
