I was trying to Root my Revvl 6 5G and I believe that I might have flashed a blank nvram.img in my bootloop recovery. Now my IMEI number is missing, and I get a signature failure anytime I try to sideload a root.zip. Is there an adb shell <command> or python mtk w <command> that can repair a missing IMEI number? Or another possible solution?

Unless you have installed a custom recovery, sideloading is restricted to original firmware images. If you try to load a non-genuine ROM you will get a signature failure. – Robert Aug 24 '23 at 07:14

That makes sense. So the missing IMEI has nothing to do with it. Unfortunately, there is no recovery.img to patch for custom recovery. I achieved root last night with a magisk_patched-boot_a.img. – NinjaAdmin Aug 24 '23 at 22:32
