Zte Zxv10 B760hs2 Custom - Firmware

The custom firmware for the ZTE ZXV10 B760HS2 , frequently used as a PTCL Smart TV box in Pakistan, is primarily designed to "unlock" the device from its original service provider restrictions. By flashing custom firmware, users typically aim to convert the restricted IPTV box into a standard Android TV box capable of running third-party apps like YouTube and various games. Key Features & Benefits

For developers and tinkerers, the challenge itself is a motivation. Bypassing the security mechanisms of a mass-produced embedded device is an intellectual puzzle. Successfully compiling a kernel, packing a system image, and flashing it over a UART serial connection provides deep satisfaction and practical knowledge of embedded Linux systems.

The breakthrough came at 3:00 AM. By bypassing the signature verification in the recovery partition, he managed to sideload a custom Android Open Source Project (AOSP)

Step-by-step (high-level) flashing checklist

  1. Identify exact hardware revision and flash size.
  2. Dump/backup current firmware and configuration.
  3. Verify the custom image is built for the exact revision.
  4. Verify checksums and package signing if applicable.
  5. Choose the least invasive flashing method supported (web UI → TFTP → serial/JTAG).
  6. Monitor the device during flashing; do not power off.
  7. After flash, factory reset and reconfigure network and Wi‑Fi settings.
  8. Test core services (WAN, LAN, Wi‑Fi, VoIP/IPTV if used).
  • "Bad Block" errors: The internal flash memory may have bad blocks. U-Boot usually handles this by skipping them, but it can cause the flash to fail.
  • No Video Output: If you flash the wrong firmware for a different hardware revision (e.g., v1 vs v2), the HDMI drivers won't load. You will hear the box boot (beeps or fan), but see no picture. Solution: You must re-flash the correct image via UART.
  • Remote Control Stops Working: The IR receiver drivers are specific. Custom ROMs are often built by the community; sometimes, the IR remote key mapping is missing. You may need to use a USB mouse or a remote app on your phone to control the box initially.
