[Google Pixel 4 Guides, News, & Discussion] i5lee8bit:
[UPDATE/KEEP ROOT GUIDE] NOV 2020 (RP1A.201105.002) "FLAME" Magisk/Stock Boot Images

IMPORTANT!! THESE FILES / THIS THREAD IS FOR PIXEL 4 "FLAME" ONLY, NOT PIXEL 4 XL "CORAL"!!

**IT IS HIGHLY RECOMMENDED TO PATCH THE STOCK BOOT IMAGE YOURSELF, FROM YOUR OWN DEVICE, USING MAGISK MANAGER. WHILE THERE'S A GOOD CHANCE THE FILE I PROVIDED BELOW WILL BE IDENTICAL (USE A FILE HASH CHECKSUM TOOL IF YOU'RE CURIOUS), THERE IS ALSO A CHANCE THEY MAY HAVE SMALL, BUT SIGNIFICANT, VARIANCES**

Thanks for the info and link, [MENTION=5964313]wrongway213[/MENTION]

-------------UPDATE PROCESS BELOW-------------

----------------------------------------------​

EASY UPDATE / SEAMLESS KEEP-ROOT UPDATE PROCESS

(using a PC - a very intuitive, effective, and relatively safe method).

** You can only follow this guide verbatim if coming

EXACTLY from build "11.0.0 (RP1A.201005.004, Oct 2020)"

. But the general idea is the same for other builds, you just need the correct files for your device.

November 2020 sideload OTA zip: https://dl.google.com/dl/android/aosp/flame-ota-rp1a.201105.002-d6fbf151.zip

DO NOT BOOT BACK INTO O/S UNTIL ALL STEPS ARE COMPLETED - THIS ENSURES EVERYTHING BOOTS BACK UP WITH MAGISK / EDXPOSED ALL RUNNING PROPERLY RIGHT AWAY

1. boot into bootloader

----------------

** I was on custom kernel, so I needed to flash BOTH the stock boot and dtbo images

2. fastboot flash boot flame-rp1a.201005.004-factory-boot.img

3. fastboot flash dtbo flame-rp1a.201005.004-factory-dtbo.img

......* these steps to restore stock recovery; dtbo.img also necessary for some kernel installations.

......* won't hurt to flash both anyway, so if you're unsure, go ahead and do both.

-----------------

4. use volume keys to change selection to boot to Recovery Mode

......- when you reach the android symbol with No Command, hold power button, tap volume up, in case you've forgotten

5. choose option "Apply update from ADB"

6. adb sideload flame-ota-rp1a.201105.002-d6fbf151.zip

7. Once the OTA sideload is done, Reboot to bootloader (you'll also notice it's now on the other slot after OTA flashed)

8. fastboot flash boot flame-rp1a.201105.002-magisk_patched-21.0.img

9. done, start the phone

(Optional - Flash custom kernel. If you had a custom kernel, you need to re-flash it)

This is a 100% seamless update that requires no additional / re-setup of any of my Magisk or EdXposed setups. All of the factory files can be found here https://developers.google.com/android/images. boot.img and dtbo.img are in their corresponding full Factory Image zips, and the ota zip is under Full OTA Images.

Please Note: I still haven't upgraded to Android 11, so the usual warnings apply. Please see previous month's update guides for additional info and troubleshooting.

And apologies about the recent tardiness on these update guides lately. Once all my preferred mods are successfully updated for Android 11, I'll actually be doing these updates myself and these guides will be much more prompt like before. =)
