In this guide, we will show you the steps to unbrick your hard-bricked Redmi Note 9. The Note series has always been known to be among the most active players in custom development. From flashing custom ROM to recoveries or gaining administrative access by rooting the device via Magisk, the possibilities stand endless. On the flip side though, carrying out these tweaks brings in a few associated risks as well.

In most cases, a softbrick or bootloop is on the cards which could easily be rectified by flashing the Fastboot ROM via Mi Flash Tool or Fastboot Commands. But things begin to turn for worse when the device gets hard bricked, as you wouldn’t be able to even access the Fastboot Mode. But if you own a Redmi Note 9, then you could still unbrick your Redmi Note 9 and bring it back to life. And in this guide, we will show you how to do just that. Follow along.
