Save pexcn/71d7d242c5e805d9346d2dc9db17fb90 to your computer and use it in GitHub Desktop.
So it's stock_boot.img
not boot_stock.img
?

Depends on which script you are running, if using badabing2005's script starting with existing boot image in /sdcard/boot.img then yes. If using the original pexcn script then he started with existing boot image called /sdcard/boot-stock.img
Easiest way is definitely repatching the stock boot image with magisk app though
thanks everyone for the hint, repatching the stock with magisk then reboot saved me from interfering with command line
you are god
Note that Pixel 7 Pro (and possibly other newer Pixel phones) are using init_boot.img
-- so you need to repack this file (not boot.img
which is also present in the OTA image!) and put /data/magisk_backup_${SHA1}/boot.img.gz
(yes, the latter path still is boot.img.gz
)
Otherwise great manual, thanks!

It appears that Android 14 uses init_boot.img and boot.img if I'm not mistaken? At least one OnePlus phones...
In case of init_boot.img
# put stock init_boot.img into /sdcard/init_boot.img
# get sha1
adb shell
su
SHA1=$(cat $(magisk --path)/.magisk/config | grep SHA1 | cut -d '=' -f 2)
# repack init_boot.img.gz
gzip -9f /sdcard/init_boot.img
# restore backup
mkdir /data/magisk_backup_${SHA1}
mv /sdcard/init_boot.img.gz /data/magisk_backup_${SHA1}/boot.img.gz
chmod -R 755 /data/magisk_backup_${SHA1}
chown -R root.root /data/magisk_backup_${SHA1}
Everyone, there's no need to calculate sha or write your own script, just use util_function.sh from the magisk folder in adb. Topjohnwu has updated it for init_boot months ago.

@giser have you tested this? Looks like it might work if when extracted it just overwrites the init_boot.img partition.
@stanleylhs indeed, but this fix doesn't always work as expected.
my phone is rooted but no /data/magisk_backup_* directories exist, so i tried to get magisk to create one. i tried using the app to patch a file. a patched boot image was created but no /data/magisk_backup_* directory. the path to the boot image was /sdcard/Documents/boot_images/init_boot_14_0_0_304.img. i tried copying it and giving it the name /sdcard/Documents/boot_images/init_boot.img and patching it. a patched boot image was created but still no /data/magisk_backup_* directory.
my phone is a US oneplus 11(cph2451) running android 14 and magisk 27.0 stable. how do i get the magisk app to patch a file and create a /data/magisk_backup_* directory?
i tried using util_functions.sh and run_migrations and that worked.
Thanks a lot for the script worked perfectly with init_boot @giser
thank you! definitely the simplest way
