Question Lost Root Access

[WhalePC]

Just recently checked and my phone no longer has root access. I'm not sure what happened as the boot.img is still there. I checked the version of my device and it updated itself automatically from 13.0.6 to 13.0.7. I am just wondering if it's because my phone updated to a different version that I lost root access.. or if it's something else. I've disabled the auto-update, but is there a way to get my root access back without having to reinstall everything from a clean slate? I'm very new to rooting so I don't understand much.

Can someone tell me why I lost root access, how to prevent it, and how to reinstall root without losing all my data? Here are the specs for my phone:

• Xiaomi MIUI Global 13.0.7 Stable
• Android Ver 12

I used this guide to root my phone previously:

The update replaced the modified boot.img.
You need to repatch the boot.img.

How do I do that and is there a way to prevent it from happening?

Same method you have already used, just in case:

Root does not delete the data.

Wait so which steps do I change to repatch? Do I just follow the steps again to get a new boot.img then patch that one in Magisk?

Exactly.

Exactly.

Hold up will I have to reinstall everything on my phone if I do this? I kind of deleted my old ROM folder on my PC

You must get the boot.img from the currently installed rom and patch it.

Okay managed to get my phone rooted again. Thanks for the help, I feel pretty dumb when it was that easy. Anyways to prevent from losing root again, do I just disable auto-update android version?

Now that you know how to do it and given the time it takes, leave the updates, important for security and proper functioning.
