Also after bootloader and downgrade via recovery, you can wipe data and erase anti rollback flag :Thanks!!
Now, a question - how does one find the OTA zip to extract boot.img from? After unlocking, my phone upgraded itself to 00WW_2_270, and it looks like I made the same mistake anfierli did before me. However, his solution no longer works - I cannot sideload-flash the 2_200 or 2_210 OTA.
At this point, I have fastboot and recovery available, but cannot load into Android. Can I try flashing the separate parts from the full 2_210 OTA via fastboot or will I screw my phone up further?
fastboot erase metadata
fastboot -w reboot
my Magisk has no original stock boot img. Not sure how any ones would since you have to fastboot flash the patched boot.img. Can u help me understand?For those rooted.
In order to avoid OTA headache, check OTA at least every two weeks.
Once OTA is available, go to Magisk and revert boot to original in uninstall.
Go to OTA and install update. DO NOT REBOOT!!!
Go back to Magisk and install on unused partition, and reboot from there
Do you have original (not patched) boot?
