Introduction
When a smartphone fails to start properly — showing only the logo and then shutting down or getting stuck on a black screen — this condition is often referred to as a “Dead Boot” issue. Devices in the Nokia / HMD Global Pulse series (such as the HMD Pulse Plus (LGD)) have occasionally faced this problem.
In such cases, flashing the official stock firmware (PAC file) can often restore the phone to working condition. The so-called Fixed Dead Boot Firmware PAC is designed specifically to recover phones that have become completely unresponsive due to firmware corruption or an interrupted update.
Overview of the HMD Pulse Series
The HMD Pulse lineup is a mid-range smartphone family from HMD Global, formerly branded under Nokia. These models typically ship with Android 14 and Qualcomm or Unisoc chipsets.
For example, firmware builds such as:
Legend_00WW/LGD:14/UP1A.231005.007/00WW_1_120
are found for Pulse devices, designed to fix issues like bootloops, dead boots, and stuck-at-logo conditions.
What Is a Firmware PAC / Stock ROM?
A Firmware PAC (or Stock ROM) is an official software package released by the device manufacturer. It contains the complete Android system, recovery, bootloader, and other partitions needed to restore the phone.
Typical uses of a Firmware PAC include:
-
Restoring a phone that won’t boot.
-
Fixing software crashes or stuck logo problems.
-
Removing FRP (Factory Reset Protection) or forgotten passwords.
-
Repairing corrupted partitions after failed updates.
Causes of the Dead Boot Problem
-
Interrupted firmware update (e.g., power loss during installation).
-
Wrong ROM flashing (using a build not meant for your model).
-
Custom ROM or root modifications gone wrong.
-
Corrupted system files due to malware or improper use.
-
Hardware damage (which software fixes can’t resolve).
How to Fix the Dead Boot Issue
⚠️ This procedure should only be attempted if you’re experienced with Android flashing tools. Incorrect use may permanently damage your phone.
-
Download the correct stock firmware PAC file for your exact model (for example, HMD Pulse Plus LGD 1520-0-00WW-B01).
-
Install the required drivers (such as SPD/Unisoc drivers if applicable).
-
Use a compatible flashing tool — e.g., SPD Flash Tool or ResearchDownload Tool.
-
Connect the device in download mode, usually by holding Volume Up + Volume Down while connecting the USB cable.
-
Load the PAC file into the flashing tool and start the flash process.
-
Wait for completion — the tool will indicate “Passed” or “Completed.”
-
Reboot the device and perform a factory reset if necessary.
Important Precautions
-
Make sure your battery is at least 50% charged.
-
Always use verified firmware sources — the wrong file may hard-brick your phone.
-
Do not disconnect the phone during flashing.
-
Flashing unofficial firmware can void your warranty.
-
If the device still doesn’t boot after flashing, the problem might be hardware-related.
Conclusion
The HMD Pulse Plus / Pulse LGD Fixed Dead Boot Firmware PAC provides a reliable solution for users dealing with a dead or unresponsive phone. By flashing the correct official stock firmware, many boot-related issues can be resolved quickly and safely.
However, flashing should be done carefully and responsibly — always verify the firmware version, use trusted sources, and ensure you follow each step accurately.
