Brand smartphones Fly, popular in the last decade, often face problems with software outdation. Over time, the device begins to work slowly, system glitches appear, and official support ceases. In such situations, the only way out is to flash the firmware yourself. This process requires care, but it allows you to bring the gadget back to life, update the Android version, or even install custom firmware with advanced capabilities.
Before taking active steps, you need to clearly understand the risks. Incorrect firmware can turn the phone into a “brick” that will not turn on. However, if all technical nuances are observed and proven tools are used, the procedure is successful. You have to choose a method for installing the software, find a compatible system image and prepare the computer.
In this article we will analyze all stages of the process: from preparatory work to restoring the system after a failure. We will look at both standard update methods and advanced methods through the mode Recovery and engineering menu. Be prepared for the fact that all data from the device will be deleted, so take care of a backup copy in advance.
Preparing the device and searching for firmware
The first and most critical stage is finding the correct system image file. For smartphones Fly this is often the most difficult task, since the manufacturer's official website is no longer actively updated. You need to know exactly the model of your device, which can be found on the sticker under the battery or in the Settings → About phonesection. An error in choosing a version, even by one letter, can lead to the touchscreen or communication module not working.
You should look for files on specialized forums, such as w3bsit3-dns.com, where enthusiasts post saved copies of original dumps and modified assemblies. When downloading an archive, be sure to check its checksum if it is specified by the author. This ensures that the file was not damaged during download and does not contain viruses.
⚠️ Warning: Never use firmware from other models, even if they look similar. Differences in display or processor drivers may make recovery impossible without special hardware.
After downloading the archive, unzip it on your computer. Usually inside there are files with the extension .img, .pac or installation scripts. Also at this stage it is worth charging the phone battery to at least 60-70%. A sudden power outage while writing data to memory (chip) is fatal to the system.
Save the original firmware, if you have it, on a separate medium. This is your only chance to return to the factory state in case of failure with custom software.
Necessary tools and drivers
To successfully flash Fly smartphones, you will need not only the image file itself, but also specialized software. Most devices of this brand run on MediaTek (MTK) processors, so the main tool will be the utility SP Flash Tool. Some older Spreadtrum-based models may require ResearchDownload.
The computer must be equipped with working USB ports, preferably located on the rear panel of the system unit, as they provide more stable power and connection. Before connecting the phone, you need to install drivers. Without them, the computer simply will not see the device in boot mode.
Installing drivers is often difficult in modern versions of Windows 10 and 11 due to digital signature verification. If automatic installation does not work, you will have to temporarily disable driver signature verification when loading the OS. After this, you can use the utility MtkDrvInst.exe or install drivers manually through Device Manager.
| Tool | Purpose | Compatibility |
|---|---|---|
| SP Flash Tool | Write an image to memory | MediaTek processors |
| ADB and Fastboot | Debugging and bootloader management | All Android devices |
| Smart Phone Flash Tool | Alternative for new MTK | Android 6.0 and higher |
| USB Deview | Removing conflicting drivers | Windows OS |
☑️ Ready for firmware
Entering Recovery and Hard Reset mode
Sometimes you don’t need a computer to flash the firmware if you have access to system recovery partition. Mode Recovery allows you to install an update from a memory card or reset the settings. To get to this menu, you need to turn off your smartphone and hold down the key combination. For different Fly models, this can be Volume up + Power or Volume down + Power.
In the recovery menu, navigation is carried out with the volume buttons, and the choice is confirmed with the power button. Here you can find the item apply update from external storageif you placed the firmware file on the SD card. However, most often this section is used to perform Wipe data/factory reset before installing a new system via a PC.
If the phone is stuck on the logo and does not boot, entering Recovery may be difficult. In this case, it helps to remove the battery (if the design allows) and try to log in again immediately after inserting the battery. On some models with a non-removable battery, you need to connect to the charger in the off state before pressing the buttons.
What to do if the Recovery menu is in Chinese?
Sometimes on Fly smartphones there is a custom Recovery with hieroglyphs. In this case, be guided by the location of the items: data reset is usually the second or third item from the top, and installation from an SD card is the fourth. You can also install the Russified TWRP menu via a computer.
Firmware process via SP Flash Tool
This is the main method for owners of devices on MediaTek chips. Run SP Flash Tool as administrator. In the field Scatter-loading File you must specify the path to the file MTxxxx_Android_scatter.txtwhich is in the folder with the unpacked firmware. This file contains a memory card and instructions for the flasher.
After loading the scatter file, all memory sections will appear in the list: boot, recovery, system, userdata and others. Make sure that all required sections are checked, especially Preloader and System. It is better to leave the firmware mode as default - Download Onlyto avoid overwriting critical areas if you are not sure of your actions.
Press the button Download (green down arrow). Now you need to connect the switched off phone to the computer. In some cases, you need to hold down the volume button (usually "Down" or both buttons) and, while holding it, connect the USB cable. The app should detect the device and begin the recording process, as indicated by the progress bar.
⚠️ Attention: If a red error window appears during the process, do not disconnect the cable immediately. Try changing the firmware mode to Firmware Upgrade or reconnect the cable to another port. An interruption during the Preloader recording stage can completely block the device.
The process takes from 2 to 10 minutes depending on the amount of memory and port speed. When completed, you will see a large green ring with a check mark. This is a signal of successful completion. Disconnect the cable and try turning on your smartphone. The first launch can last up to 5-10 minutes, as the system optimizes applications.
The green ring in the SP Flash Tool is the only indicator of success. If it does not appear, the firmware was not written correctly, even if the progress bar reached the end.
Solution (of common problems)
Often users are faced with a situation where the computer does not see the phone. In 90% of cases the problem lies in the drivers or cable. Try replacing the USB cable with a known good one, preferably an original or high-quality analogue that supports data transfer, and not just charging.
Another common mistake is STATUS_CHKSUM_ERROR. It occurs if the firmware file does not match the bootloader version in the phone. The solution is to find a more recent or, conversely, older version of the dump file. It is also worth trying to uncheck the section Preloader in the firmware list if you do not plan to update it.
If after the firmware the phone turns on, but the touch screen does not respond to touches, it means that the firmware from a different display revision was installed. In this case, you will have to look for a dump specifically for your hardware version of the board. Sometimes resetting the settings via Recovery after installing the software helps.
- 🔄 Error 4032: Try formatting the partition table (Format All + Download), but this will delete the IMEI.
- 🔋 The phone does not turn on: Connect to charger for 30 minutes, the battery may have gone into a deep discharge.
- 💻 Device Manager does not respond: Reinstall VCOM drivers in Windows signature debug mode.
IMEI restoration and final setup
After successful firmware, especially if the format mode was used, the IMEI number may disappear. This is critical for the operation of the cellular network. You can check the availability of a number by typing the command *#06# in the phone dialing mode. If Null is displayed instead of numbers or there is no line, recovery will be required.
To restore IMEI on MTK processors, use the utility SN Write Tool or MauiMeta. You will need the IMEI information, which is usually located on a sticker under the battery or on the box of the device. The process involves connecting the phone in META mode (often you need to hold down the volume buttons when connecting) and writing new values in the appropriate fields.
After the connection is restored, configure the smartphone again. It is recommended that you do not restore all applications and settings from Google backup at once, but set up your device as new. This will help you understand if the performance issue that may have caused the firmware has been resolved. Install only the necessary applications and test the work for a couple of days.
⚠️ Warning: Changing or faking IMEI is illegal in most countries. Restore only the original number assigned to the manufacturer of your device.
Frequently asked questions (FAQ)
Is it safe to flash a Fly phone yourself?
