Hey there, let's walk through how to unbrick your Intex Aqua Y2 Pro step by step. First off, do NOT use the Intex Aqua V10 OTA package—different device models have incompatible firmware, and flashing that will only make the problem way worse. Let's focus on the right approaches:

1. First, Try Getting Your Computer to Recognize the Device #

If we can get your PC to detect the device, we have more rescue options. Here's what to do:

• Boot into Fastboot Mode: For most Intex devices, hold the Power + Volume Down keys (or try Power + Volume Up if that doesn't work) while the device is off. Keep holding until you see the Fastboot screen.
• Install Correct USB Drivers:
  • If you can't find official Intex drivers, try generic Android USB drivers (included with Android Studio's SDK Platform Tools, or from trusted driver tools).
  • Connect the device to your PC, open Device Manager. If you see an "Unknown Device" or "Android Device" with a yellow exclamation, right-click it > Update Driver > Browse my computer for drivers, then point to the driver files you downloaded.

2. Use Stock Recovery with the Correct Stock ROM (Not OTA from Another Model) #

Since you want to use the "Apply update from SD card" option in Stock Recovery, you need the exact stock firmware for Intex Aqua Y2 Pro—not a different model's OTA. Here's how to find it:

• Check Intex's official support website first: Search for your device model and look for firmware download sections.
• Look for dedicated Android tech forums: Search threads for "Intex Aqua Y2 Pro stock ROM"—you'll often find users sharing verified firmware packages. Make sure to check user comments to confirm the package works for your device.
• Verify the firmware package: Always check if the post includes an MD5 hash to confirm the file isn't corrupted.

3. Flash the Stock ROM via Stock Recovery #

Once you have the correct stock ROM:

• Format an SD card to FAT32 (use a 32GB or smaller card, as some older Recoveries can't read larger ones).
• Copy the stock ROM zip file to the root directory of the SD card (don't put it inside folders).
• Boot into Stock Recovery: Hold Power + Volume Up keys while the device is off until the Recovery menu appears.
• Select "Apply update from SD card" (or the equivalent option in your Recovery's language), navigate to the ROM zip file, and confirm the flash.
• After flashing completes, select "Wipe Data/Factory Reset" to clear any leftover modified system files that might cause another boot loop.
• Finally, select "Reboot system now" and wait for the device to boot up (this might take a few minutes, be patient).

4. If Stock Recovery Isn't Accessible #

If you can't get into Stock Recovery at all, you'll need to use a tool like SP Flash Tool for a line flash—but this requires your PC to recognize the device first. So go back to step 1 and make sure the drivers are installed correctly.

Quick Tip for the Future #

Before modifying build.prop again, always back up the original file! Use a root file explorer to copy the original build.prop to your SD card or cloud storage—this way you can restore it quickly if something goes wrong.
