This is what you need to download the Symphony stock ROMs, aka Symphony firmware flash files, for all Symphony mobile devices.

Flashing stock ROMs can help you update to newer or older versions of Android, fix bugs, unbrick the mobile devices, remove root access and custom recovery images, so forth.

The Symphony stock ROMs that you find here in this guide are no different to the Symphony firmware that you get as over the air updates. The only difference is that you are flashing the files manually yourself whereas an automatic OTA update would download the files for you using the internet connection.

Any OTA updates that may have arrived for your Symphony mobile device will become available to you if it is a newer version of Android compared to the version you are flashing here, and you’ll be able to accept and install them, as you would usually expect, when they become available too.

Each mobile device carrier network usually has their own stock ROMs for their specific model numbers. You should always flash the stock ROM that is made for your carrier network if your device is still locked to that carrier. On the other hand, if your device is unlocked from the carrier, then you can install the stock ROMs intended for other carrier networks just fine. If the stock ROMs are not labeled as for any carrier network on the page, then it’s because it is an unbranded stock ROM, meaning you can install it on any device with the same name, no matter the carrier network.

What not to do with stock ROMs: don’t ever flash a stock ROM that was made for another device. It won’t work and it’ll soft-brick your device until you manage to get the correct ROM flashed again.

What Is Android Firmware?

Firmware is the operating system and its applications that control how the smartphone or tablet that runs on Android operates. While you may see the words “software update available” on your device’s display, we call it firmware to highlight its close relationship with the device manufacturers hardware.

If you prefer technical jargon, firmware is the specific programming that gets written to a device’s non-volatile memory. The firmware gets added to the device during the manufacturing process and is the middleman in helping software run on the hardware. Firmware can be written as read-only memory (ROM), erasable programmable read-only memory (EPROM), or flash memory.

The Android operating system is more open than much of its competitors in iOS, Windows 10 Mobile, and Tizen. You always get firmware running on your device out of the box, but if you do not like it, you can swap it over with custom firmware or other firmware versions that were made for your device. This flexibility helps with troubleshooting, or if you know you would prefer a different Android version that was made available.

Why Reinstall Stock Firmware?

Here are some of the things that you can achieve with stock firmware files:

  • Upgrade or downgrade the version of Android on your device
  • Fix common mobile device-related problems, such as unbearable bugs in the software
  • Remove custom recovery images such as TWRP
  • Unroot the Android operating system, regardless of what method/tool you may have used to get root access
  • Unbrick your smartphone or tablet
  • Reinstall the operating system
  • Fix invalid IMEI problems

Although we always do our best to make sure all external sources are safe, it’s safe practice to view the WOT reputation and VirusTotal scan results before downloading links to your computer.

Note before flashing: the guide for the SP flash tool — the most commonly used flash tool — can be used for everyone who has a device with a MediaTek chipset.

Those of you with a device that has a Qualcomm chipset can use other flashing tools such as the QcomDloader tool or Qualcomm Flash Image Loader (QFIL).

MediaTek and Qualcomm make up most chipsets, but occasionally a device can also have a Spreadtrum,  Broadcom or Rockchip system chip, in which case you should use the tools designed for those system chips instead.

For the odd rare occasion, some of you may need to use the Miracle Box software which can be downloaded from a search engine such as Google.

Lastly, follow the guides here if you have to install a PAC file or flash an RDA bin file.

2. Turn off the mobile device by holding the Power button in until the screen turns off.

Important Notes

[*] Back Up Your Data: You should always back up your data before you begin flashing new firmware files to your smartphone or tablet. All of your pictures, music, videos, documents, etc. should be still on your device after you have updated the firmware, but you may need to restore the contacts and applications from a backup.

[*] Wipe Cache and Factory Reset: Some people claim that taking a factory reset isn’t necessary after updates, but at the very least you should wipe the system cache after installing new firmware. This way you can help eliminate any performance issues and battery draining bugs. Taking a factory reset is the best way of avoiding common problems many users face after applying software updates.
