The Acer Holo 360 (model DC100) is a unique all-in-one camera that captures 360-degree video and photos and can share them directly via Wi-Fi or LTE. It is powered by the reliable Qualcomm Snapdragon 625 (MSM8953) chipset and runs a full version of Android 7.1.1 Nougat. This guide provides the official stock firmware for the device.
This is a complete stock ROM package designed to be installed using the Qualcomm Flash Image Loader (QFIL) tool. It is the perfect solution for unbricking a device that is stuck in a bootloop, experiencing software crashes, or is completely unresponsive.
Disclaimer: Flashing this firmware will perform a clean install of the operating system, erasing all data from the camera’s internal storage, including any photos, videos, and settings. Please back up your data if possible before you begin. Proceed at your own risk.

How to Flash Stock Firmware
To restore the firmware on your Acer Holo 360, you must use the QFIL tool and boot the device into EDL (Emergency Download) Mode. First, ensure the correct Qualcomm 9008 drivers are installed on your Windows PC. Power off the camera completely. Then, press and hold both the Up and Down volume buttons simultaneously while connecting it to your PC with a USB cable. Your PC should detect it as “Qualcomm HS-USB QDLoader 9008”. Next, launch QFIL, select “Flat Build,” and load the programmer file (e.g., prog_emmc_firehose_8953_ddr.mbn) and the rawprogram/patch XML files from the extracted firmware folder. Finally, click the “Download” button to begin flashing.

Device-Specific Troubleshooting for Acer Holo 360 (DC100)
- Struggling to Enter EDL Mode: If the volume button method doesn’t work, try connecting the USB cable first and then holding the buttons. If the device is completely bricked and unresponsive, it may require using “EDL test points” on the motherboard, which is an advanced procedure that involves opening the device.
- QFIL Errors: “Sahara” or “FireHose Failed”: These are the most common QFIL errors. A Sahara error usually indicates a problem with the initial handshake, often caused by incorrect or conflicting USB drivers. A FireHose error typically points to an issue with the programmer file or an unstable connection. Ensure you are using the correct
.mbnprogrammer file included in the firmware package and try a different USB port/cable. - “No Port Available” in QFIL: This message means the camera is not being detected by your computer in the correct mode. Check Windows Device Manager. If you don’t see “Qualcomm HS-USB QDLoader 9008” under Ports (COM & LPT), the drivers are not installed correctly, or the device is not in EDL mode.
- Firmware For Camera Only: Although this device runs Android, its firmware is highly specialized. Do not attempt to flash it on any other phone or tablet, even if it has the same Snapdragon 625 chipset.
FAQs
- Q1. My Acer Holo 360 is stuck on the boot screen. Will this firmware fix it?
- Yes. This full QFIL firmware package is designed to fix software issues like bootloops, system crashes, and devices that won’t fully boot up by completely reinstalling the operating system.
- Q2. Will flashing this firmware erase the photos and videos on the camera?
- Yes, this process will completely wipe the camera’s 16GB internal storage. Any media that has not been backed up or transferred to a microSD card will be permanently deleted.
- Q3. What is EDL Mode?
- EDL (Emergency Download) Mode is a special, low-level recovery mode on Qualcomm-powered devices. It allows tools like QFIL to communicate directly with the device’s storage, making it possible to flash firmware even when the device appears to be bricked.
- Q4. Why does QFIL show an error and fail to flash?
- The most common reasons for failure are driver issues. Ensure you have uninstalled any other mobile drivers and installed only the Qualcomm QDLoader 9008 drivers. Using a high-quality USB cable and a mainboard USB 2.0 port on your PC can also improve stability.
