Describe the bug

I upgraded my device (Oneplus 11R / Oneplus Ace 2) from ColorOS 14 (Android 14) to ColorOS 15 (Android 15) today (20240124). Before the upgrade, I uninstalled KernelSU. After the upgrade was completed, I was on the official system and my network was functioning normally. Then I got the boot.img from the update.zip and patched it using the v1.0.2 version from the Releases,. And I flashed it by "fastboot flash boot xxx.img". After that, I installed the modules I commonly use. Suddenly, I found that I was unable to access the network at this point.

The "unable to access the network" I mentioned here refers to: "Wi-Fi and 5G connections look normal, but regular apps cannot access the network."

I tried using Termux to ping my gateway and external ips. They could all be pinged successfully. However, when I used curl to access any website (domains and ips), it prompted "curl: (52) Empty reply from server". I tried both mobile data and Wi-Fi, and the result was the same.

First I suspect this is an issue with my routing table. After switching to root, I used a command to view the routing table. It looked like this:

.../files/home # route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.219.71.96    0.0.0.0         255.255.255.252 U     0      0        0 rmnet_data2
192.168.2.0     0.0.0.0         255.255.255.0   U     0      0        0 wlan0

I manually added routes, but it didn't help.

During this period, I attempted to switch to the CI branch version, which exhibited the same issue. Initially, I thought it might be sporadic, so I conducted multiple reboots to test for intermittency, like the screenshot

Through continuous testing, I discovered that as long as I install any module, I will be unable to access the network after a reboot. Uninstalling it through KernelSU does not help. I have to use the complete uninstallation option in the KernelSU settings. Only after rebooting can I access the network again.

To Reproduce

Using a Oneplus Ace 2, install KernelSU and any module, then reboot.

Expected behavior

The module is functioning properly, and network access is normal.

I tried reinstalling and enabled this option, but it didn't work for me. I’m currently backing up my data and preparing to flash the stock firmware, then install KernelSU afterward.

I have backuped my data and used fastboot -w to wipe the data. Subsequently, I encountered google's frp protection . At this point, I tried to install KernelSU but found that after flashing the boot.img, it did not recognize that I had installed it (no logs were generated). Later, I wiped the frp partition content in fastbootd and cleared the data again. Finally everything goes well.

I am not entirely sure why this issue occurred, but my problem has been resolved. I will keep this issue open.
