Anyone know the difference between the two builds?
"Within the .19 image META-INF\com\android\metadata, the post-timestamp UNIX value is 1565300664 which equates to 08/08/2019 @ 9:44pm (UTC).
Within the .20 image META-INF\com\android\metadata, the post-timestamp UNIX value is 1565743352 which equates to 08/14/2019 @ 12:42am (UTC).
Based on one of Google's release tool's code, this value seems to be utilized to determine whether it should perform an incremental or full OTA.
If I'm understanding their upgrade process correctly, the .19 image does not contain the September security patch. The .20 appears to be the full stable release with the September security patch.
It would appear .19 should support an incremental upgrade from the latest Android Pie (9) version, PQ3B.190801.002 but not bring you to the latest September security patch.
This leads me to believe that the .20 image is suitable for almost all OTAs. There may be carrier specific cases that one or the other should be utilized but nothing stands out too clearly within any of the immediately available metadata files."

I have just got the ota update, I'm updating from beta 6 and it's saying the update size is 41mb, is this correct?

They have diferent checksums
A factory image is a full replacement - and is meant to replace everything (you'll lose all your data and else that isn't backed up). An OTA is an update - you lose nothing. If you're coming from a STOCK factory image (either a beta of 10 OR 9) and your phone is fine, you want the OTA; otherwise (including AOSP), you want the full factory image.

I didn't want to wait for the OTA to be pushed to my phone, so I sideloaded it and the rooted it again with Magisk. My directions are accurate if anyone else wants to sideload the OTA. To be honest, the whole process is faster when you sideload anyway. So it is really a better solution than waiting for the OTA.

The initial boot took about 5 minutes. Don't get impatient and try to mess with the phone. Just let it do it's thing.

Thank you sic0048! I followed your guide when my Pixel 3a was on 9 and it was smooth. The best instructions I have found and even bookmarked it.

I do have one quick question. I followed your instructions about updating the phone and keeping root, but I lost root after reboot. I probably did something wrong. :silly:

In your instructions under the "Custom Recovery Installation method" you state that TWRP doesn't support Android 10. So how do I root my phone again? Is it safe to use this method or should I use another one of your methods in this tutorial?
