Hello,

I just installed the Update 9.0.2 for the Onplus 6
OnePlus6Oxygen_22_OTA_027_all_1810260000_d46787d2c9.zip

Usually I shut my mobile off during night and charge it.

The usual bahavior of the mobile is
switching on to charge mode ->
Bootloader unlocked warning ->
afterwards animation of charging the battery.

With the new firmware it stays at the Bootloader unlocked warning screen.
I checked already Magisk Versions 17.1, 17.2, 17.3.
Magisk Uninstall / reverse to stock boot image solved the behavior.
Dalvik Cache were cleaned.
Complete reset / format of all partition didn't solved it.

I think there is a bug with the magisk patched boot image that is causing the not switching inzo charge only mode.
Previous firmwares for Oneplus 6 had no issues with charging while being off.

Update: its an issue of the Stock Rom from oneplus.
9.0.2 freezing at bootloader warning
9.0.3 charge like expected
9.0.4 freezing at bootloader warning

I have the same problem on a OnePlus 6 running the latest open beta 6 with canary release. Open beta 5 was working ok.

I have the same problem. Stuck in bootloader warning while charging.
When you change the current slot in TWRP from Slot B (current) to Slot A and power off the phone and replug to charger, the phone shows the charging animation.
After a reboot and another "power off charging" you'll have the same problem as above.

Same here with 9.0.2, magisk 17.1 (latest stable), I will add that this bug appear installing 9.0, when I updated to 9.0.1 this problem disappear but when updated to 9.0.2 (so partition changed) this bug return so I reflashed (changing the slot another time) but the bug is still there.

Same issue. Any build 17.1-17.4.xxxx on Canary does not work.

    The problem still exists with Magisk v18

    And it will likely keep existing... There's nothing in Magisk v18.0 that is supposed to fix this issue. Actually, from the research that has been done, it is quite likely that there's nothing that Magisk can do about it at all. It seems like that this will be an issue as long as the kernel has been patched to force boot with ramdisk, something that isn't specific for Magisk, but quite essential.

    There where reports of OxygenOS Beta 7 having fixed the issue (and beta 8 breaking it again), so the ball seems to be with OnePlus.

    Bumping this for visibility and to see if anyone has found a solution, or if @topjonhuw has seen this issue reported.

    Can confirm that Open Beta 7 with magisk 17.3 fixes the charging screen however Open Beta 8 with magisk 17.3 breaks it again.

    Hi guys, the German Android Forum was bringing to these thread...
    Can't confirm that OnePlus 6t isn't charging while rooted and off
    Only the charge animation you won't see because op6t is showing the yellow warning message about open bootloader.
    Try it for yourself.
