Magisk Manager 280 can't dump NAND boot image on some devices
What is the issue I have:
- Magisk Manager does not find boot.img, but
/data/adb/magisk/busybox nandwrite /dev/bootimg /sdcard/boot.imgworks.
Log from the console:
Unable to detect target image
Installation failed
In which version of Magisk Manager is this happening:
Canary Debug be8479fd (280)聽聽聽[Build date: March 30, 2020]
Stable 7.5.1 (267) (7)聽聽聽聽聽聽聽聽聽聽聽[Build date: March 28, 2020]

Try 280, and also what's the location of your boot partition?
Edit: Nevermind, I see /dev/bootimg there. On other devices it finds /dev/bootimg fine. Not sure what's up there.

Try 280
Same..
Is there anything I can help you with? The situation is strange.

Could be related/similar to #2609, I wonder.

Do you have a working TWRP? Does flashing the Magisk zip work there?

There is only CWM recovery for my device. The flashable Magisk zip also does not detect boot image.

@Msprg, are things still working well on your NAND device?
@Msprg & @martobg10, can you both please give me the output of ls -al /dev/block on your devices while in recovery?
@martobg10, did it work with any older Magisk version?

@martobg10, did it work with any older Magisk version?
@osm0sis, please see this log I think it will help. This is the log from recovery.
What are my steps:
- I boot device in recovery
- I flashed Magisk 20.2
- I flashed Magisk 20.3
- I flashed Magisk 20.4
- Reboot in system
Full recovery log:

Things that I noticed:

You didn't really answer my question.. I don't think this has ever worked on your device before, am I right?
I have an idea why it doesn't work. There is no by-name or named partitions under /dev/block, so find_block fails entirely there, which leaves the fallback in find_boot_image.
Can you try grep -v '#' /etc/*fstab* | grep -E '/boot[^a-zA-Z]' | grep -oE '/dev/[a-zA-Z0-9_./-]*' | head -n 1 in recovery?

Awesome. I'll add both fixes. :wink:
My guess is it works on other devices like @Msprg's because it also has by-name links under /dev/block or something.

Okay I got Magisk 20.401 (ef9d077c), Installation from TWRP seems to be working flawlessly. Instalation through Manager (canary) does not work.

Hmm that didn't explain how it works for yours and not his.. and I'd like to figure that out before I change anything.
@Msprg, can you try in recovery
ls -al /dev
and
find /dev/block -type l -iname boot | head -n 1
find /dev/block -type l -iname bootimg | head -n 1
aand
grep -v '#' /etc/*fstab* | grep -E '/boot[^a-zA-Z]' | grep -oE '/dev/[a-zA-Z0-9_./-]*' | head -n 1
aaand
toupper() { echo "$@" | tr '[:lower:]' '[:upper:]'; }
grep_prop() {
local REGEX="s/^$1=//p"
shift
local FILES=$@
sed -n "$REGEX" $FILES 2>/dev/null | head -n 1
}
for uevent in /sys/dev/block/*/uevent; do
local DEVNAME=`grep_prop DEVNAME $uevent`
local PARTNAME=`grep_prop PARTNAME $uevent`
if [ "`toupper bootimg`" = "`toupper $PARTNAME`" ]; then
echo /dev/block/$DEVNAME
break
fi
done

@martobg10, please show me the output of grep -v '#' /etc/*fstab* | grep -E '/boot(img)?[^a-zA-Z]' | grep -oE '/dev/[a-zA-Z0-9_./-]*' | head -n 1 as my previous change broke it on other devices. :roll_eyes:

Aha! So something is laid out differently in your fstabs and that's why it finds /dev/bootimg on your device and not the OP's. Awesome.
Finally, @Msprg, please do:
grep -v '#' /etc/*fstab* | grep -E '/boot(img)?[^a-zA-Z]' | grep -oE '/dev/[a-zA-Z0-9_./-]*' | head -n 1
and then
find /dev \( -type b -o -type c -o -type l \) -iname bootimg | head -n 1

in /etc I have file fstab (content:)
/dev/block/mmcblk0p6 /cache ext4 rw 0 0
/dev/block/mmcblk0p7 /data ext4 rw 0 0
/dev/block/mmcblk0p5 /system ext4 rw 0 0
/dev/block/mmcblk1p1 /external_sd vfat rw 0 0
and recovery.fstab (content:)
# mount point fstype device [device2]
/boot emmc /dev/bootimg flags=display="Kernel";backup=1
/logo emmc /dev/logo flags=display="Logo";backup=1
/cache ext4 /emmc@cache flags=display="Cache";wipeingui;backup=1
/data ext4 /emmc@usrdata flags=display="data";storage;wipeingui;backup=1
/nvram emmc /dev/nvram flags=display="Nvram";backup=1
/recovery emmc /dev/recovery flags=display="Recovery";backup=1
/system ext4 /emmc@android flags=display="System";wipeingui;backup=1
/external_sd auto /dev/block/mmcblk1p1 /dev/block/mmcblk1 flags=display="MicroSD";storage;wipeingui;removable
Both of your grep and find commands, as you have written them, sucessfully found /dev/bootimg

Oh yes, @osm0sis and what about that magisk manager direct flashing not working? Is it suposed to be that way, RN, or is it someting still broken in canary manager?

Yep, that confirms it.
@Msprg's recovery.fstab has the boot line like this:
/boot emmc /dev/bootimg flags=display="Kernel";backup=1
where @martobg10's has:
/dev/bootimg /bootimg emmc defaults defaults
so it having it as /boot is why it could be found by the original find_boot_image fstab fallback while in recovery.
I believe fixing both those functions (find_block and find_boot_image) with my PR will get it working everywhere for you guys. :+1:

Awesome. I'll add both fixes. :wink:
My guess is it works on other devices like @Msprg's because it also has by-name links under /dev/block or something.
