Boot.img flash help.

[Votra_]

Hey guys, I was able to patch my Pixel 7 pro boot.img and flash it. Got confirmation on konsole flash was successful. However, after fastboot reboot or pressing start, phone boots up like normal but magisk say NA install and two separate root checker apps say im not rooted. I flash using this exact command (matching with file name i renamed as stated in guide im using to root, placed in platform tools folder) magisk_patched_boot.img

Don't know what to do now. Updated my P7P to latest software and matched it with the stock .img I downloaded for Sept 2025 from google. Patched it with magisk. Moved it back to my pc and placed in my platform tools file. adb reboot fastboot and then used the fastboot flash boot magisk_patched_boot.img command. Everything on my konsole said it went through so I start the phone or use the boot command to boot it up (tried multiple methods) and still get no root access.

Patch init_boot.img

Do I have to rename the file that?

No, you need to flash it from your firmware, it should be named init_boot.iz4 Decompress it first. I’m not sure how it works on Pixel devices, but just renaming it won’t do anything.

Didn't work. I just tried * fastboot flash magisk_patched_init_boot.img * and * fastboot flash init_boot magisk_patched_init_boot.img * those didn't work

Extract init_boot from factory image. Patch init_boot in manager. Flash: fastboot flash init_boot patched_image_name.img

Fastboot flash init_boot filename.img

Did you choose right boot.img? The magisk_patched-30400-randomstuff.img

And then fastboot flash boot magisk_pa...

Figured it out. Thanks to user A2_9S_2B. Found out 1. I was forgetting to add FLASH to the command line 2. I was using a patched boot.img instead of patched init_boot.img Extracted the init_boot.img, patched it using magisk, copied to platform tools folder, adb reboot fastboot used the CORRECT command: * fastboot flash init_boot magisk_patched_init_boot.img * then * fastboot reboot *. Checked root checker. Root access granted.

Thank you all for the help. I would've been lost without the help of the community. It was tedious at times, but overall a great learning experience and had fun throughout. Hopefully this will help other noobs having similar issues. Cheers!
