Flashing of OPPO F1s can be complicated, especially for those who lack the technical know-how of smartphone firmware and software updates. However, when one has the essential guidance and understands the concept, a flash of the device can offer many benefits, like fixing software problems, updating or downgrading Android version, or even installing a custom ROM. This detailed guide will take you through most of what you’d want to know about flashing OPPO F1s, such as the reasons behind flashing, the stepwise procedures, associated risks, and those of benefits.
1. Introduction to Flashing
1.1 What Is Flashing?
Flashing in the smartphone domain means installing (or reinstalling) an operating system (OS) or firmware on a device. It has its uses: installation can be used to fix bugs, remove bloatware, upgrade to a new version of the OS, or downgrade to one older. With OPPO F1s, flashing would be useful when the device has been slowed down or become unresponsive- basically when there are software problems on the unit.
1.2 Why Do you Need to Flash Your OPPO F1s?
There can be several reasons for flashing one’s OPPO F1s. Below are some of the common causes:
Software Malfunctions: It means problems, crashes, or errors which cannot be fixed by normal means of fixes could possibly be resolved by flashing the firmware, since it gives the installation of the operating system from scratch.
Bloatware: If your OPPO F1s came with many apps loaded into it or even bloatware, flashing the newer version of the firmware will get rid of those apps and give a slight boost to the system resources.
Upgrade or Downgrade the OS: You might want to upgrade into the latest Android version from there with some more latest features, with the latest security updates, or rather you might want to downgrade if the new one has some slight bugs or incompatibility with some apps.
Custom ROM Installation: For the advanced people out there, flashing at times means giving a custom ROM, which can give them much more personal experiences, custom features, themes, and optimizations variously not presented in the stock firmware.
Device Recovery: In some situations, flashing has saved the OPPO F1s to make it work after bricking due to a failed software update or something similar.
2. Preparation for Flashing
2.1 Backup Your Data
Before flooding your OPPO F1s, the user should back up all important data because during the flashing, everything will be deleted from the device: applications, contacts, photos, settings, and so on. Here are some ways to back up your data:
Google Account: Back up contacts, emails, and app data with a Google account. Go to Settings > Accounts > Google and make sure everything is synced.
OPPO Cloud: The OPPO devices have an OPPO Cloud service that backs up photos, contacts, and related data. You will find it in Settings > OPPO Cloud.
External Storage: Transfer photos, videos, or whatever you need to back up to an external SD card or a computer.
2.2 Download the Necessary Tools and Firmware
To flash, the OPPO F1s must have a set of tools and the appropriate firmware file downloaded. Here’s what you’ll need:
SP Flash Tool: This is the tool used for flashing the firmware to OPPO F1s. It is compatible with MediaTek processor, which the OPPO F1s is equipped with.
Firmware File: You will need the official firmware file for the OPPO F1s, sometimes also called the ROM file. Kindly ensure to download the right version for your model.
USB Drivers: These are drivers for the OPPO F1s that allow communication between the device and your PC during the flashing process.
Scatter File: A scatter file is simply a text file containing information about the memory structure of the device. Usually, it comes bundled with the firmware file and is required for the SP Flash Tool.
2.3 Installing Drivers and Tools
Now that you have everything downloaded, you need to install the USB drivers on your computer for SP Flash Tool to recognize the device. The drivers installation goes as follows:
Extract the ZIP file with the USB Driver you downloaded.
Run the setup file and follow the on-screen prompts to install the drivers.
Restart your computer before proceeding to ensure successful installation of the drivers.
Now, go ahead and extract the SP Flash Tool and firmware file on your computer, making sure the scatter file persists within the same directory as the firmware files.
3. Flashing Process
3.1 Booting the OPPO F1s into Download Mode
Before you could flash the firmware, the OPPO F1s needed to be booted into Download Mode so the SP Flash Tool could interface with the device during flashing. To enter Download Mode:
Consider turning your device OFF.
Connect your OPPO F1s to your computer via USB cable while holding the Volume Down button, which should boot the device into Download Mode.
3.2 Flashing with SP Flash Tool
Your device is now in Download mode and connected to the computer. You can go ahead with the flashing process using SP Flash Tool. First:
Launch SP Flash Tool on your computer.
Hit the “Choose” button situated next to the “Scatter-loading File” field.
Browse to the folder where you extracted the files and load the scatter file.
From within the SP Flash Tool interface, double-check that all partitions are selected. You may want to leave “Preloader” unchecked if you wish not to overwrite the bootloader of your device. But all this is for the advanced users.
Click the “Download” button to begin flashing the procedure.
3.3 Completing the Flashing Process
After clicking the Download button, SP Flash Tool will initialize and start flashing the firmware on your OPPO F1s. This could take several minutes, depending on the size of the firmware file and the speed of your computer.
You must avoid disconnecting the device from the computer while this process is ongoing, as that could lead the device to brick.
The SP Flash Tool will display a progress bar to show the procedure status.
When the procedure ends, a message Download OK with a green circle will appear.
You may now safely disconnect your OPPO F1s from your computer. The device should reboot by itself, and you shall see the setup screen for the firmware you just flashed.
4. Post-Flashing Steps
4.1 Setting Up Your Device
After flashing the firmware, your OPPO F1s should boot into the freshly installed OS. You will now have to set the device up for the first time going through options such as selecting language, connecting to WiFi, signing into Google Account, and setting your preferences.
4.2 Data Restoration
After setting your device, you can restore all the data you backed up before flashing:
Google Account: By signing into your Google account, the system will try to automatically restore your contacts, emails, and app data.
OPPO Cloud: From the Settings, you can also restore data backed up to OPPO Cloud.
External Storage: Transfer files back to the device, which might include photos or videos from external SD Card or a computer.
4.3 Verifying Firmware Installation
To verify the successful installation of your firmware on an OPPO F1s, you should check the software version:

5. Troubleshooting Common Issues
5.1 Flashing Errors
During the flashing process, you may encounter errors in the SP Flash Tool. Typical issues are as follows:
“PMT changed for the ROM; it must be downloaded” Error: This error mostly occurs if the partition table of the device does not match the scatter file. In such a case, use the format option of the SP Flash Tool and format the device before flashing the firmware.
BROM ERROR: S_FT_ENABLE_DRAM_FAIL-The Error: This error has been related to memory issues. Make sure that the firmware file is compatible with your device model, and try flashing again.
Device Not Recognized: If your computer does not recognize your OPPO F1s, make sure that USB drivers are installed. It could also be a problem with your USB cable or yards-the USB port itself.
5.2 Boot Loop Issues
If your OPPO F1s is in a boot loop (keeps restarting and never actually booting):
Try entering Recovery Mode by pressing Volume Down and Power simultaneously;
Perform a factory reset in Recovery Mode. This will delete all data from the device but could resolve the boot loop issue;
Re-flash the firmware using SP Flash Tool, selecting all partitions.
5.3 Bricked Device
There are also rare cases when the OPPO F1s could’ve been bricked during flashing, i.e., it will not boot off at all. If this happens:
Try flashing again via SP Flash Tool. Remember to select the ‘Firmware Upgrade’ option instead of ’Download Only’ so that all partitions can be rewritten.
Make sure to use the “Format All + Download” option in the SP Flash Tool to completely format the device and re-inject the firmware. This will wipe off everything from the device, including the IMEI number, so it should be your last resort.
5.4. IMEI Loss
After the flashing, if you find that your OPPO F1s has lost the IMEI number, which is required for calling and using mobile data, follow the steps below for restoration:
*Dial #06# to check if your IMEI number is missing.
Use the SN Write Tool-This tool will allow you to re-write the IMEI number to the phone. You need to input the original IMEI number, which can be found usually on the box of the phone or under the battery.
Follow the directions of the SN Write Tool to restore your IMEI; this requires use of a PC and some technical know-how, so proceed with caution.
