Hey there!
Absolutely, trying to create an image of your phone is a smart move before diving into any recovery efforts. This way, you keep the original data as untouched as possible, increasing your chances of getting those deleted bits back.
Regarding your question about doing this without root access, yes, it's possible, though it might be a bit more limited compared to having full root privileges. For Android phones, tools like ADB (Android Debug Bridge) can help you create a backup of your phone’s data without needing to root it. ADB allows you to interface with your device more directly from a computer, and with the right commands, you can pull a lot of data off the phone. However, it might not be as comprehensive as a full image you’d get with root access.
For creating an image, you can use ADB to execute a command like adb backup -apk -shared -all -f /path/to/backup.ab on your computer with your phone connected. This will create a backup file (.ab) you can then use with data recovery programs. Keep in mind, the success of recovering deleted calls and messages depends heavily on how the phone has been used since the data was deleted. If new data has been written over the areas where the old data was stored, recovery might be challenging.
As for recovery programs, there are several out there, but it’s crucial to choose one that’s reputable and preferably recommended by tech experts. Some programs are designed to work with the backup files created by tools like ADB.
Lastly, if the information is super crucial, you might also consider consulting with a professional data recovery service. They often have more powerful tools and techniques at their disposal for retrieving lost data. I've had a personal experience with SALVAGEDATA that was pretty positive. I reached out to them a while back when I accidentally wiped an entire drive on my laptop – we're talking about years of work and personal memories that I thought were gone for good. They were able to recover nearly everything, which was a huge relief. They specialize in all kinds of data recovery services, so they might be able to help with your phone data, too.
