I had to. I tried without removing first, but got the error. Removed and everything went smooth.
No problem with blu_spark 9.91, not necessary to remove compatibility.zip ! :good:
My way to update android 9 Pie open bêta :
-In Twrp 3.2.3 v9.85 blu_spark -> flash Magisk uninstaller -> flash OBx (without compatibility.zip) -> flash Magisk 18 -> wipe cache/dalvik -> reboot system -> All done ! :good::fingers-crossed:
Fantastic, very good job :good:
Work fine for Belgium Orange carrier
I use the simple method of downloading the full Update ZIP to my phone, rebooting to TWRP, clearing caches, flashing the Update ZIP, flashing Magisk, clearing caches and reboot. That way always worked for me.
No need for such a complicated proces...
I've had my phone for 3 days, just started, I did the update and a factory reset directly.
I did a test by cutting the mobile data at night and over 8 hours I lose 1% on the battery.
So for me it's very good! :good:
