You can't just install patched boot.img like that. It will not be missed by the verification system. That's why I used vbmeta and vbmeta_patch which are included in the instructions.May I ask if you just used magisk manager to patch boot, cause when I do I get error on flash.
And how did you patch vbmeta?Code:(bootloader) is-logical:boot_a: not found Sending 'boot_a' (33792 KB) OKAY [ 1.172s] Writing 'boot_a' FAILED (Status read failed (Too many links))
I'm just curious since this patched boot isn't the latest and I wonder how to make this work with the latest boot.img from September patch update.
You can patched up any boot.img yourself and try to install it by following the instructions. But I can't guarantee how this will work on a working system. You have to try it.
