Anyone else having problems with the Wifi/hotspot? I only got it after installing 3.09 on my android 11 (lineageOS)


Jan 6, 2008
Hoping someone might be able to help me out. I'm a relative newb to the EX Kernel manager and to flashing kernels in general, though I've been a root (and occasional ROM) user since the OG Motorola Droid.

I was able to flash the EX Kernel on the February update without issue, but I just flashed the March update and can't get the EX kernel installed again. I keep getting "Flash Failed" error when trying to flash with the auto flash option in EX Kernel Manager.

Pixel 3XL, rooted with Magisk (tried both stable and canary versions with same result.) I have no modules beside Busybox enabled in Magisk.

Any ideas?

Perhaps similar to GohanBurner last November, I'm ending up with a stuck Google logo on boot after flashing P3-3.14 from the app.

I just updated stock Android 11 March update, re-rooted with Magisk (22), and then use EXKM to flash the kernel. Upon reboot my phone sits at the Google logo. A reboot into fastboot and then reflashing the Magisk modified boot.img clears the issue but of course without the ElementalX kernel.

Any thoughts?

New 3.17 for June is broken. Freezes on boot screen. Google logo just hangs without any movement indicator.
Tried twice
Are you using June image? I can't test on this device, but I have updated my 3aXL, which is virtually the same and had no problems.

edit: I think there may be a problem with the file, I am re-uploading (which will take a long time because of my crappy internet)

    Stay up to date with EX Kernel Manager. The latest security updates are always available through the app, usually within hours of the latest OTA. EXKM can be used to configure settings, backup and flash zips and img files, run scripts and install kernel updates quickly and easily. EXKM is compatible with all devices and kernels and is the best and most complete kernel manager available.

    You can also use High Brightness Mode so you can see your phone in the sun. This app unlocks the hidden hardware setting that makes your screen much brighter than stock. HBM requires root.

    -October security update
    I have the app. If what you want is for us to pay you, fine. I've already paid for the kernel manager app AND the HBM app. I don't care about the money. I just want a HBM that doesn't suck, and the app sucks compared to the new "google HBM" (not to mention it's an app, another thing we have to download and set up and give permissions to).

    I don't agree with the excuse that "it's not supposed to remain on". The whole point of the kernel app is to let us tweak and overclock and automate things that we "aren't supposed to". At least give us the option to let it remain on. It's method for handling high brightness across the slider range is better than how the HBM app does it.

    Why don't you just code it up yourself then
    EX Kernel Manager 3.74 is rolling out on the Play Store now...

    It adds full spport for the Pixel 3 XL, including vibration control, HBM setting and ability to download and directly flash ElementalX or any other kernel that uses the AnyKernel2 format.

    There are two new settings for the wake gestures:
    Vibrate on wake: This will vibrate when you use a gesture to wake the device (e.g. sweep2wake or double tap)
    Vibrate on sweep2sleep: This will vibrate when you use sweep2sleep to turn off the screen

    High brightness mode works a bit differently on this device. Instead of going to max, it just increases the backlight at the current brightness setting. I will add support to my HBM app soon. I may also change this behavior in the kernel, as I prefer it to just go to max on demand.
