How come Magisk did not back up my stock boot image?

[Droid_Nut]

Hi all I got a 7T in the US. I got an update notification, and i wanted to uninstall Magisk, perform the update, reinstall Magisk and reboot. In Magisk I get the message, "stock image does not exist." I never had this problem with my Pixel, how can I get Magisk to save an image after I update and reroot?

Thanks

Why do you want to uninstall magisk?

1. Install update and don't reboot.
2. Go to magisk and install after ota
3. Reboot

I don't know about restore stock image with magisk and never did that.
If you really want to unroot your phone now, download the correct boot.img and flash it. There are a few threads available here to find that image you need.
Also you can download the ota.zip and dump that payload.bin which is inside the zip.

Like kollachi said, you don't need to follow the standard pattern of uninstall/ota/install-inactive with the 7t. I imagine that's because with a rooted device, it pulls the full rom instead of a diff.

But it sounds like you directly flashed a rooted boot.img which is why magisk doesn't have a backup. Instead, you should have done a `fastboot boot patched_boot.img` and then done a magisk install. It would have taken a backup of your original boot.img and then installed a patched version.

So basically install the Ota right over root, open magisk manager and install root, then finally reboot?

With the pixels and others, you have to uninstall magisk with restore boot image, install the update, install magisk again, then reboot.

Thanks for all of the help.

I installed magisk with twrp, the twrp that you boot off of pc into temporary memory.

it's the same procedure you're used to. you just don't need to uninstall first since it's a full ota instead of a diff

Just wondering, will it back up my new stock boot image after the update, and the install from Magisk Manager?

No I don't think so. I can't find anything on my phone.

I guess it really does not matter, considering we don't have to uninstall root.

 

[ziddey]

yes it does..

backups are saved to /data/magisk_backup_<hash>/boot.img.gz

I have one for every time I've (re)installed magisk

I still do not have a backup I did the OTA, and then reinstalled Magisk "Direct Install (Recommended)", but I guess I should have picked "After OTA to slot A or B" as I had no root on reboot. So I had to TWRP it back to root.

Lots to learn, but I am gaining. :good:

Yep the correct way is install after ota.

I mean you did that last time and it didn't backup your boot. Fair to assume you'll get the same results if you do it again.

When you install to inactive next time, it should create a backup since the boot image will be intact

With the Pixel it always recommended install to inactive slot and I went with what was recommended.

Hi,

I was trying to update my OnePlus 7t to 10.3.3HD65AA but I am not able to do it. This is what I am doing
1) downloading the update package from oxygen updater application
2) going to setting then in system update I am clicking on more option and then on selecting local update then selecting the package waiting for upgrade to complete.
3) now going to magisk manager and installing the manager in inactive slot and rebooting the device

The phone gets reboot but doesn't update also attaching my magisk log here

I used method 3 to root my 7T a while back and did the update from 10.0.9 to 10.0.11 this morning. Did you do the full update? AFAIK the incremental update won't work

1. Used Oxygen Updater to download the update (DO NOT FOLLOW THEIR INSTALLATION INSTRUCTIONS)
2. Did local upgrade from Settings/System/System updates (options wheel) DO NOT REBOOT
3. Opened Magisk Manager and did a direct reinstall of Magisk (not manager) then
4. Installed Magisk into inactive slot
5. Reboot.
