  1. If you hid Magisk unhide it.
  2. Remove all Magisk Modules
  3. Remove -w from flash-all.sh
  4. Yes

My Magisk has stopped working recently. I had set it to hidden. Now when I try to open it, keeps prompting me to "upgrade to full magisk manager to finish the setup". I click OK but Magisk never starts.

Is it safe to uninstall Magisk and just reinstall it?

Hi, I root my phone the usual way at every update by patching boot.img with magisk.
After a clean install of the April update, after flashing the boot_patched.img, I loose data connection : no SIM card detected, and no IMEI. With both stable and canary magisk.
When I restore/uninstall magisk, I loose root but my SIM and my EMEI are back.
Do you have any idea?
Thanks!

Provided you are not on Verizon:
Try reinstalling the stock boot.img from the update, flash the OTA, or perform another clean install. After first boot and performing any necessary setup (if clean install), power off phone, remove sim card, reboot. Creat a new patched boot.img, install it and reboot. Turn phone off, reinstall sim card, reboot as normal. Should fix the issue. Make sure you are using the latest magisk (I prefer stable of canary personally but it's your call).
If you are on verizon, do not install the April update in this thread, as it is stated "All carriers EXCEPT Verizon."

However, there is an OTA update on the official frimware website that does work on Verizon. I just flashed it myself. Maybe Homeboy76 could update thread?

:( Do not repeat do not follow these instructions. The information is only partially correct. :(

I just checked the Factory image and the OTA image pages the only change was the All carriers EXCEPT Verizon has been removed from the images description.

The OP has been updated to reflect the change.

These images work on Verizon Pixel 4a 5g phones.

I think something went wrong during the patching or flashing process.
- Make sure you are using the latest SDK Platform-tools r31.0.2.
- Do #7 Patching the boot.img for your Pixel 4a 5g again, using Magisk Canary 22103.

my build?
If your phone is 100 percent stock, the boot.img should be extracted from the latest Google Factoy image.

If you have a Custom ROM installed follow the instructions in the OP of the Custom ROM you installed.

:oops: In this case follow your instructions, maybe. :unsure:

    Thanks for the write-up. Just got one of these as I dropped my old phone, and I was due anyways. So question regarding Safetynet. I went ahead and went with the latest Feb factory image, patched the boot and rooted with Magisk, then tried the safety net and attestation fails. Anybody have the feb patch and passing safetynet? if so what was the sequence you used? thanks
    - Root with Magisk patched img
    - Open Magisk Manager install SafetyNet module
    - Reboot
    - Open Magisk Manager Enable Magisk hide
    - Hide Google Play store, Google pay, etc
    - Clear cache and storage for the above apps
    - Reboot
