The Firehose programmer file was sent to the RAM, but it failed to initialize control over the flash storage, or the file does not match the processor variant.
Look for a file named exactly or similarly to prog_emmc_firehose_8917_ddr.mbn or a specialized asset matching the QM215 architecture verified for Nokia 1.4.
Using Firehose Loader on your Nokia 1.4 device comes with some risks and precautions:
Reinstall your Qualcomm drivers, try a different USB port (preferably USB 2.0), or re-verify your test point connection. Nokia 1.4 Firehose Loader
This is the most critical and controversial step. Firehose loaders are . Using the wrong one will either fail or permanently brick the device.

This is for educational purposes. Proceed at your own risk.
When the device enters (via hardware key combo or forced empty boot), the PBL listens on USB for a Sahara protocol handshake. The host sends the Firehose loader to RAM, where it authenticates (using Qualcomm’s secure boot chain) and executes.
When searching for or verifying a compatible loader file, it must align perfectly with the core hardware profile of the Nokia 1.4: Specification Nokia 1.4 (TA-1322) Processor (SoC) Qualcomm Snapdragon 215 (QM215) Architecture 28nm Quad-core Cortex-A53 Storage Type File Format Required Unencrypted, signed .mbn or .bin Essential Requirements Before Flashing This is the most critical and controversial step
Before reaching for the Firehose, try these:
Modern Nokia devices, including the Nokia 1.4, typically block the adb reboot edl software command, and fastboot commands are unavailable in EDL mode. The only reliable way to force a Nokia 1.4 into EDL mode is via a "Test Point" hardware method: disassembling the phone and physically shorting two specific points (small metal contacts) on the circuit board to force the boot ROM to enter emergency download mode. The exact test point locations for the Nokia 1.4 are available on professional repair forums, and this technique should only be performed by experienced individuals. An alternative is using a specialized "EDL cable," which automates the shorting process without full disassembly.
