no Magisk after flashing, "cp: can't preserve ownership... Operation not permitted"
MCOfficer opened this issue · comments
Device: Nokia 3.1 (TA-1063)
Android version: 10
Magisk version name: 27002
Magisk version code: 19f15f1 (27002) (D)
Freshly unlocked bootloader, no previous root or custom rom. Dumped partitions with mtkclient, checked which A/B slot is active, then patched boot_b.bin with Magisk.

Then flash:
❯ adb reboot bootloader
❯ fastboot flash boot_b magisk_patched-27002_bE4nD.img
Sending 'boot_b' (24576 KB) OKAY [ 0.873s]
Writing 'boot_b' OKAY [ 1.198s]
Finished. Total time: 2.075s
❯ fastboot reboot
Rebooting OKAY [ 0.000s]
Finished. Total time: 1.054s
Confirm slot B is indeed still active after the reboot:
❯ adb shell /bin/getprop ro.boot.slot_suffix
_b
But no root, Magisk app also says "Installed: N/A"
❯ adb shell magisk
/system/bin/sh: magisk: inaccessible or not found
(might be a duplicate of #8081)
The device boots & functions fine, on the surface nothing has changed compared to stock ROM.

(this bugreport was generated with the patched boot_b.img applied, as detailed above)
I don't think this bugreport was captured right after boot as requested, because logs are quite late.
Further, I saw unofficial magisk in your log, and we have no support for them.
Last, I think /sbin/su can grant you root.
Close.
I don't think this bugreport was captured right after boot as requested, because logs are quite late.
Ah, i misunderstood. Here's a bugreport captured immediately after a reboot:
bugreport-Essential2_00WW-QP1A.190711.020-2024-06-18-16-29-54.zip
Further, I saw unofficial magisk in your log, and we have no support for them.
I have an unofficial magisk app (Kitsune) installed from an earlier attempt, (nevermind, apparently i already removed that. i don't know what app you saw...)
everything in this issue relates to offical magisk. I made sure to flash my clean, stock boot_b.bin to undo this attempt, and only used official magisk in the steps detailed above. If you are not convinced, i can wipe all traces of Kitsune and try to reproduce once more. Please reopen.
Last, I think
/sbin/sucan grant you root.
❯ adb shell /sbin/su
/system/bin/sh: /sbin/su: inaccessible or not found
the log does not help because there're full of garbage.
try adb shell ls /sbin and adb shell /sbin/magisk su
Ah, that turned up something:
❯ adb shell ls /sbin
ls: /sbin/stub.apk: Permission denied
ls: /sbin/magisk: Permission denied
ls: /sbin/magiskinit: Permission denied
resetprop
su
supolicy
❯ adb shell /sbin/magisk su
/system/bin/sh: /sbin/magisk: inaccessible or not found
If you know of a way to generate cleaner logs, i'd be happy to do that.
Edit in case this helps:
❯ adb shell ls -la /sbin
ls: /sbin/stub.apk: Permission denied
ls: /sbin/magisk: Permission denied
total 4
ls: /sbin/magiskinit: Permission denied
drwxr-xr-x 3 root root 180 2024-06-18 16:27 .
drwxr-xr-x 20 root root 4096 2009-01-01 01:00 ..
drwx--x--x 7 root root 160 2024-06-18 16:27 .magisk

lrwxrwxrwx 1 root root 14 2024-06-18 16:27 supolicy -> ./magiskpolicy
Since there was no unofficial magisk involved, and things in /sbin are clearly not working as expected, can this be reopened?
