Itel A37 Firmware (Flash File) – Drivers, Tools & Guide
On this page, you’ll find everything needed to restore your Itel A37. We have the official Itel A37 stock firmware (PAC file), the ResearchDownload (SPD) Flash Tool, Spreadtrum USB drivers, and more. We’ll help you choose the correct flash file for your specific build, region, and model, offer direct download links, and guide you on how to verify and unzip the package. Following that, you’ll find step-by-step flashing instructions. You’ll also learn how to repair a missing IMEI, troubleshoot common errors, get answers to frequently asked questions, and discover tips for safe flashing, with support available. Let’s get started.
Before you flash your smartphone, please make sure the downloaded ZIP file isn’t corrupted and that the firmware matches your specific A37 model. You will need a Windows computer and a reliable USB cable to connect your smartphone. It’s also a good idea to scan your computer for malware before beginning the flashing process. Refer to the “How to Flash” guide provided below this post for straightforward flashing instructions.
Your Itel A37 firmware package is usually compressed in ZIP format. If you have already downloaded it, you can extract it using WinRAR or 7-Zip. If not, download and extract it. After extracting the file, open the folder and confirm that it contains the PAC file (it will look something like A37_Android_xx.pac) before proceeding with the flashing.
Remember that updating the stock firmware on your Itel device will erase all data. This is beneficial because it resolves various software issues. These can include FRP lock, app problems, slow performance, forgotten pattern locks, issues where the phone is dead or stuck on the Itel logo, Wi-Fi and Bluetooth connectivity problems, battery draining issues, or soft brick situations.
Itel A37 FRP Bypass
After flashing your device or doing a factory reset, you might run into a Google account lock, also called FRP. If that happens our free Android apps launcher can help you get back into your phone.
Why Do We Need Itel A37 Firmware?
The firmware is crucial because it helps improve your phone’s performance and fix common issues. It can:
- Unlock your device.
- Update your phone to the latest Android system.
- Fix problems like startup loops, lagging, and freezing.

This simple update can make your device work better and more reliably. You can learn more about stock ROM.
Choosing the Right Firmware Version
Before you begin the flashing process, follow these steps to select the correct firmware:
- Identify Your Device Model: In “About Phone,” confirm that your model is indeed the Itel A37.
- Verify the Build Number: Look for identifiers like “A37” within your device’s build details.
- Confirm the Chipset: According to Itel specifications, the A37 is powered by a Quad-core 1.3 GHz UniSoC Spreadtrum SC7731E (32nm) processor.
- Match the Firmware Version: Check the firmware version and regional details to ensure they are compatible with your device’s specifications. This helps avoid potential issues.
- Verify In Recovery Mode: If you are unsure about your A37’s chipset or firmware version, you can restart your device into recovery mode to check additional details. To enter recovery mode on Itel phones, power it off and wait for about 8 seconds. Then, press and hold the Power and Volume Up buttons until you see the Itel logo, at which point you should release the Power button but continue holding the Volume Up button. You will then see an “Android No command” screen; release the Volume Up button. Next, press and hold the Power button again and tap the Volume Up button. This method helps you identify the correct firmware to flash and which version works best, minimizing risks.
