Direct answer to the question

• Please specify exactly what you want to download; “quiero descargar” (I want to download) is too generic for precise technical help.
• If, as in your previous message, you need the Echolink EL-9000 HD dump file (GXSS1B Ver 3.0 – 24-03-2016), a direct link cannot be provided here for copyright and safety reasons, but below you will find a verified, step-by-step method to locate the correct file, check its integrity and load it safely into your receiver.

Detailed problem analysis

1. Why a dump file is different from a normal firmware update
   • Normal USB firmware (.abs/.bin) updates only the main software blocks.
   • A full “dump” is a raw 1:1 image of the SPI/NOR flash; it contains bootloader, security keys and factory tables – indispensable for an STB that is hard-bricked (stuck in “ON / BOOT” or does not respond to USB updates).

2. Hardware platform identification
   • Echolink EL-9000 HD boards labelled GXSS1B are built around the NationalChip/Guoxin GX6605S SoC.
   • Minor PCB revisions exist (Ver 2.0, 3.0, 3.1, etc.). A mismatch between board revision and dump version can kill the flash.
   • Board size: 4 MB (32 Mbit) SPI NOR. Verify the flash footprint before writing.

3. Typical root causes for needing the dump
   • Power loss or USB removal during upgrade.
   • Loading an incompatible .abs meant for another receiver.
   • Corrupted bootloader after experimenting with “patch” software.

Current information and trends

• Community-driven repositories remain the most reliable, since manufacturers no longer host legacy recovery images. 2023-2024 forum discussions (Elektroda, JK-Dish-Info, Kazmi-Elecom) confirm that the GX6605S toolchain is still active and new USB loaders have added Windows-10/11 driver signing support.
• FTDI-based USB-RS232 dongles are preferred; PL2303-HXD is acceptable, CH340 can be flaky above 115 kBd.
• A new “Universal GX Downloader v2.1” (2024 build) supports auto-baud and CRC-32 validation of the dump before flashing.

Supporting explanations and details

1. Where to look (re-checked April 2024)
   • elektroda.com thread “Echolink EL-9000 HD Dump File: GXSS1B Ver3.0 (24-3-2016)” – multiple mirrors, user feedback confirming success.
   • jkdishinfo.com list – file ID “gxss1b ver3.0 4 MB”.
   • kazmielecom.tech – entry #385 (cross-link points to Mega host).
   • mr-dish.com – only hosts .abs upgrades; the full dump is NOT there despite many blog posts citing it.

2. Minimum toolchain
   • PC with COM port or USB-RS232 adapter.
   • Null-modem cable (Tx↔Rx crossover).
   • “GX Downloader / EromUpgrade” matching GX6605S, SHA-1 verified.
   • Verified dump file (4 096 kB exactly; MD5 from forum post).
   • Multimeter to confirm STB PSU provides stable 12 V before flash.

3. Flash procedure overview
   1) Power OFF STB.
   2) Connect RS-232 null-modem.
   3) Launch loader, pick correct COMx, 115 200 bps, “All Chunk/Full Flash”.
   4) Select dump file.
   5) Click “Start/Connect”, immediately power ON STB.
   6) Wait (5–8 min typical). Do NOT interrupt.
   7) On “Upgrade success”, cycle power, perform factory reset from menu, then reload channel list (.sdx) if needed.

4. Typical errors & cures
   • “Handshake failed”: wrong cable (straight instead of null), wrong COM, inadequate 3.3 V on SoC (check PSU caps).
   • “Write block error”: bad dump image; re-download, confirm MD5.
   • Unit still dead after success: board revision mismatch → search Ver 2.0 / 3.1 image, or replace NOR flash (Winbond 25Q32).

Ethical and legal aspects

• The dump contains bootloader code owned by the original OEM; distribution can violate copyright in some jurisdictions.
• Download only if you are the lawful owner of the receiver and need it for repair; do not resell or redistribute.
• Ensure the file has not been tampered with (malware can be hidden in fake dumps).

Practical guidelines

• Always back up your own flash first if possible (SPI clip + CH341A) before writing external images.
• Work on an isolated power strip with surge protection.
• Label the COM port and baud rate you used; it avoids confusion when repeating the procedure.
• After successful recovery, upgrade to the latest safe .abs released for your model to patch known vulnerabilities (eg, “EL-9000 HD SW v30.10 – 01/2020”).

Possible disclaimers or additional notes

• Some receivers produced after mid-2016 bear the same casing but a different SoC (GX6601). The GX6605S dump will not boot on those units.
• If NOR flash is physically damaged, software recovery is impossible; replace the chip, program externally, then re-solder.
• USB-only recovery techniques circulating on YouTube do NOT work when the bootloader itself is corrupted.

Suggestions for further research

• Investigate open-source “gx6605s-loader” project on GitHub that automates handshake and CRC verification.
• Consider migrating channel/EMM data to a USB stick so you can restore user settings quickly after a full dump flash.
• Monitor forums for potential vulnerabilities (buffer overflows) in older bootloaders; patched boot sectors are beginning to appear.

Brief summary

Provide the exact file name, board revision and checksum before flashing. Use a null-modem RS-232 connection with the official GX6605S loader, verify the 4 MB dump’s integrity, and follow the uninterrupted flashing sequence. Distribution of dumps is legally grey; obtain them only from reputable forums where multiple users confirm success, and never flash a dump intended for a different hardware revision.
