Nie, dziękuję Przekieruj mnie tamFlash Dump star-x99plus
• A legally-redistributable flash-dump (raw .bin image) for the STAR-X 99 Plus satellite receiver cannot be supplied here, because the file is proprietary to the manufacturer.
• If you need it for recovery or analysis you must either (a) extract it yourself with a SPI-flash programmer, or (b) download a community-supplied dump/firmware from reputable satellite-receiver forums such as Khan Dish Network, Mr-Dish, TeckWiki, or Telegram groups (e.g. satDL).
• Always verify that the dump matches: model = STAR-X 99 Plus, PCB revision, and Flash-IC size (commonly W25Q32 / W25Q64, 4–8 MB).
Device architecture
• SoC family: most STAR-X 99 Plus units use ALi M352x or Sunplus 150x.
• External SPI-NOR flash (SOIC-8) 4 MiB or 8 MiB stores bootloader (u-boot), proprietary middleware, channel database and user settings.
Typical failure modes that require a flash dump
• Stuck on boot logo (“ON” or “LOAD” on 7-segment).
• Dead after interrupted USB upgrade.
• Corrupted user database causing continuous reboot.
Recovery paths
a) Soft recovery (preferred)
• Vendor USB upgrade: rename official “.abs/.bin” to rom.bin (or as instructed), copy to FAT32 USB, power-cycle while holding “OK/CH+” to invoke mass-storage loader.
• ALi emergency loader via RS-232 (STB_Loader 1.0.0.x) – requires null-modem cable and PC.
b) Hard recovery (flash programmer)
• Tools: CH341A, TL866II-Plus, RT-809H.

How to locate a compatible flash dump
• Search keys:
“STAR-X 99 Plus dump”, “X99 PLUS 4MB/8MB bin”, “STAR-X X99 Laser flash”
• Known mirrors (checked Feb-2024):
– https://khandishnetwork.com (file size ≈ 2.9 MB, post 11-Dec-2024)
– https://www.mr-dish.com/star-x-99-plus
– Telegram channel @satDL (message #692 contains “FLASH DUMP-Star x 99 Laser.rar”)
• Cross-check MD5/SHA-1 posted by other users; ensure file length matches IC capacity.
Verification before flashing
• Compare boot-header string (first 0x20 bytes) with your backup.
• Confirm kernel CRC in footer (many ALi images store CRC32 at offset 0x7FFA0 for 4 MB).
• Check DVB-S2 tuner ID (mismatch may break demodulator driver).
• Community sites have begun distributing partial dumps (bootloader + kernel only) to minimise copyright risk.
• Newer STAR-X models (X2024) switched to eMMC; raw dumps are ~8 GB and require different programmers (e.g. SD-card adapters + mmc util).
• Shift toward secure-boot: future receivers may have signed NOR images, blocking third-party dumps.
Analogy: Think of the SPI-NOR as the receiver’s “SSD”. A flash dump is a sector-for-sector clone; if you write a clone from a board with different hardware revision, the driver “inf file” may be wrong, akin to cloning a Windows image from Intel to AMD. Hence hardware match is critical.
• Firmware is copyright of Star-X/ALi; distributing it without permission can breach IP law.
• Many dumps circulating online include patched key-sharing code (card-sharing, CCCAM lines) which is illegal in many jurisdictions.
• Always use dumps strictly for lawful device recovery.
Hardware preparation
• Use antistatic wrist strap; flash IC pins are ESD-sensitive.
• Power the CH341A from 3.3 V only; 5 V will destroy W25Qxx.
Best practices
• Keep three backups: raw.bin, verified.bin, and zipped copy off-site.
• Label file with board-revision and date, e.g. X99Plus_PCB-V1.3_W25Q32_2024-02-22.bin.
• After restore, immediately perform official USB upgrade to latest firmware to patch security holes.
Common challenges & fixes
• “Chip not detected”: lift /CS or VCC pin, add 1 kΩ pull-up; nearby regulator may hold bus busy.
• Receiver boots but no signal: tuner I²C address differs; transplant original tuner section from own dump (offset 0x600000-0x607FFF in 8 MB image).
• No warranty: using an incompatible dump can irreversibly brick the STB.
• Model naming confusion: “STAR-X 99 Plus”, “X-99 Laser” and “StarX X99 HD” are sometimes interchanged online; verify silkscreen on PCB.
• Investigate open-source ALi SDK replacements (e.g. stbemu-ali) for community-driven firmware.
• Study secure-boot chains in later ALi SoCs and feasibility of JTAG unlock.
• Evaluate shifting to Linux-based DVB STBs (e.g. Enigma2 on Hisilicon) which have official image repositories, reducing need for raw dumps.
A flash dump for the STAR-X 99 Plus is primarily used for hard recovery when official USB/RS232 procedures fail. Because the binary is proprietary, it must be sourced from your own device via a SPI programmer or from trusted satellite-receiver communities. Match hardware revision, back up the original contents, and use verified tools (CH341A, TL866). Be mindful of copyright and legal constraints, and always prefer official firmware updates when available.
