App Info shows it's Magisk Manager 7.3.2
The program itself shows Magisk Manager 7.3.3 (224)

On S10 here it is showing: Installed 7.3.2(224)
Latest 7.3.2(224)

Another S10 on which Magisk is working displays:
Installed 7.3.1-1058aeb0 (225)
Latest 7.3.1-1058aeb0 (225)

Usually have option of 'Direct install of Magisk with Magisk Manager but
with this version have to download ZIP file and then select it for installation.
Displays the following when attempting to install via Manager:

Not enough info

[elig0n]

Please explain what info you need ?
This is not a good reason to close an issue and no way of handling an issue.

I got the same error but managed to install the zip via TWRP.

You might try installing the canary builds with debug.

Does anyone got any updates on this ? I also used this release and got the same error.

Thank you

I am having the same issue, I thought it was me, but not matter how I download and install Magisk, it gives me this error

[satisfy123]

Having the same issue!

[NathanielRMoss]

same issue on 4 S4galaxy phones. Continually asks me to update Magisk Manager, even though the manager is up to date. Then No Direct install option anymore.

Same on OnePlus 6 without TWRP.

[takuhii]

I manually installed Magisk 19.4, and it now tells me the latest version is Magisk 19.3 :/

[yusea431]

Got the same issue to elig0n, and my device platform is armeabi v7a . Many times i installed/reinstalled but still...

[Eisenherz254]

I am also getting the same error on Magisk v7.3.5(243). My device is Ulefone Note 7 running on Android 8.1 Go Edition. Any advise please?

[h6w]

Ok, I think there's a misunderstanding of the process here. For my reference, and others, the "Download Patch File" is NOT the file you then "Install". You must:
1) Download the patch file
2) Patch your boot.img with the patch file on another machine
3) Patch the boot with fastboot boot patch_boot.img
4) Without rebooting, run Magisk Manager and select "install into slot".
Then, and only then, will the system be patched and stay patched!

You only get into this problem situation if you do an OTA update and then reboot. If you do an OTA update in future, go to Magisk Manager before rebooting!

@h6w

Patch your boot.img with the patch file on another machine

How?

[Canhobix]

Enter on fastboot mode

fastboot flash boot.img

Please note that you should flash the boot.img of your phone model and baseband switch.

@h6w

Patch your boot.img with the patch file on another machine

How?

[KestrelSoftworks]

@h6w Just tried patching a LineageOS boot.img the way you say since I'm facing the same issue. It keeps saying "Unsupported/Unknown image format"
The img file is attached.
boot_img.zip
Is there anything I can try to make this work? Or any pipeline you can suggest me to tweak the img file or needed thing?
Thank you in advance.

@Marco-Sulla @KestrelSoftworks That depends on your phone.

e.g. For OnePlus6,

How to extract from OTA and manually patch stock OOS boot.img using Magisk Manager:

1. Install python3 and PIP manager on your system .

2. Use pip to install "protobuf" module:

   pip3 install protobuf

3. Download payload_dumper.py and update_metadata_pb2.py from this gist https://gist.github.com/ius/42bd02a5...342ab7a9c60f15 and save them in one directory.

4. Download full update zip with OOS (containing payload.bin). It can be downloaded from this great thread by @Titokhan
5. Extract payload.bin from update zip to same directory where payload_dumper.py is located.

6. Use payload_dumper.py to extract original boot.img

   python payload_dumper.py payload.bin

After a while you should have all img's included in payload.bin dumped in your working directory.

1. Install Magisk Manager app on your OP6.
2. Place that dumped boot.img on your phone storage.
3. In Magisk Manager app tap install, and select "Patching boot image file". Select boot.img that you've just uploaded to your phone.
4. Magisk Manager will patch boot.img and save it on Phone's internal storage in "MagiskManager" directory (file called "patched_boot.img").
5. Download this patched file to your computer and just use it to boot using fastboot

Downloading the gists was a bit tricky, but this process worked for me. :-)

You can also download pre-patched boot images from here for OnePlus6.

Well, I'll find a way for my phone, a Xiaomi Redmi Note 6 pro with Andorid 9 and MIUI 10.3.6.

PS: a question: flashing the boot image via Magisk, not via fastboot, requires an unlocked phone?

[h6w]

Unlocked, yes.  And the caveat is that some brands (e.g. Samsung) now have eFuses, which means once you unlock them, it voids your warranty. OnePlus is one of the few brands that encourage people to use alternative ROMs so they don't have an eFuse. :-)On 19 Nov. 2019 00:51, Marco Sulla [e-mail] wrote:Well, I'll find a way for my phone, a Xiaomi Redmi Note 6 pro with Andorid 9 and MIUI 10.3.6.

If anyone stumbles over this issue like me:

The issue was that magisk is not recognizing the firmware archive that is loaded from sammobile etc. You have to unpack the firmware and you will see 5 files, one of them is AP_ something tar.md5

Upload the file to your phone, patch it with magisk, download to PC and flash it with odin, but also flash all the other files in the archive.
