Pixel 4 "FLAME" March 2020 QQ2A.200305.003 boot.img - Stock and Magisk v20.4 Patched

Hey all, I just updated my wife's P4 to Magisk 20.4 as of yesterday and have had no issues so far on the new version (nor on my P4XL). Here are the stock and recently newly updated Magisk patched (v20.4) boot images. I couldn't direct install the update on either of the phones via Magisk Manager, so I figured I would share these images.

Stock March 2020 boot image: https://www.androidfilehost.com/?fid=4349826312261757144
Magisk Patched (v20.4) March 2020 boot image: https://www.androidfilehost.com/?fid=4349826312261757143

Remember, these are ONLY for those on QQ2A.200305.003 firmware already. Don't flash if you don't know what you're doing.

Hey i5lee8bit,
Thanks for posting the p4 OTA boot files. worked perfectly. I have a p4xl as well. How do I extract the boot image from the device? I can not find the new boot image online from google or anything.

Which method did you use to flash? I've tried it a few different ways and they don't work. I'm thinking on factory resetting and trying again but I don't want to do if I don't have to. I've had no problem rooting my pixel 4 on any of the other updates but for some reason I can't root the March update. It looks like things flash fine but when the phone reboots it gets to a black screen and just stays there. I know it can take a while during app optimization so I let it set over night. Still on a black screen the next morning.

I'm not sure, I just grab them from the factory images (https://developers.google.com/android/images#coral). If it's not there, I wouldn't know. I came from years of HTC devices, but even then we either used TWRP or RUU decryption tool / firmware zips. Not sure if there's a way to extract directly from the device using dd or adb commands, but even then that was done using TWRP. Not sure if there's an alternate method; I'm not the right person to ask either, sorry. Tulsadiver's thread that I linked to for the other guy mentions a boot.img extractor, but I've never used it.

But if the boot file I provided worked perfectly for you, I would assume that means you are using the USA Unlocked model, and it should be available on the developers.google.com link I posted.

From bootloader, just the simple fastboot flash boot name_of_boot_image.img

It sounds like you OTA'd to the March build? And you previously had it Magisk rooted on a prior firmware version? It could be a module not playing nice. Maybe try booting into Magisk Core mode, see Tulsadiver's thread: https://forum.xda-developers.com/pixel-4/how-to/magisk-modules-disabler-booting-magisk-t3991739


Sorry for the delayed responses btw. Quarantine + work + school + new baby = wtf.

Thanks for the reply. I ended up getting it to work using the "payload_dumper-win64" method i found in another thread to extract the boot.img from the payload.bin file. Turns out the OTA file was online from google.

To updatePixel 4 xl with "coral-ota-qq2a.200305.003-3b25765d" MAach update OTA software:
- uninstalled Magisk
-updated software
-reinstalled magisk
-patched the boot img from payload.bin
-pushed modified boot to device
-Done
Everything seems to be working well. I got to use python for the first time, so that was kind of fun. I was a flashing machine back around the galaxy s4.

I got root working. Spent so much time trying different things and all I had to do was factory reset my phone. There must have been some file or module interfering with the process. Once I reset my phone the root process went without error. ?*
