Zero-kernel 0.6.4 + Magisk bootloop on OnePlus 5T / LineageOS 22.2 (Android 15) - Need help!

[termuxman555]

Hello zero-kernel developer,

I'm completely stuck and need your help. I've tried everything to get Magisk working with your kernel on my OnePlus 5T (dumpling) running LineageOS 22.2 (Android 15), but I always end up in a bootloop. Let me explain exactly what I tried:

My Setup:

• Device: OnePlus 5T (A5010, dumpling)
• ROM: LineageOS 22.2 (20260106 nightly) - Android 15
• Recovery: TWRP 3.7.1_12-2
• Kernel: zero-0.6.4-dumplinger-los-4.4.zip
• Magisk: v30.7

What I tried:

Attempt #1 (zero kernel FIRST, then Magisk patch):

1. Clean flash in TWRP:
   • Flashed zero-0.6.4-dumplinger-los-4.4.zip
   • Flashed lineage-22.2-20260106-nightly-dumpling-signed.zip
   • Flashed Disable_Dm-Verity_ForceEncrypt.zip
2. Booted system once (everything worked fine with zero kernel)
3. Back to TWRP, dumped current boot partition:
   dd if=/dev/block/by-name/boot of=/sdcard/zero_boot.img
4. Patched zero_boot.img with Magisk Manager ("Select and Patch a File")
5. Flashed the patched image back via TWRP (Install Image -> Boot)
6. Result: Bootloop (phone stuck at boot animation or black screen)

Attempt #2 (Magisk patch FIRST, then zero kernel):

1. Clean flash in TWRP (without zero kernel this time):

• Flashed lineage-22.2-20260106-nightly-dumpling-signed.zip
• Flashed Disable_Dm-Verity_ForceEncrypt.zip

2. Booted system once (stock kernel, no zero yet)

3. Back to TWRP, dumped stock boot.img:
   dd if=/dev/block/by-name/boot of=/sdcard/stock_boot.img

4. Patched stock_boot.img with Magisk Manager

5. Flashed patched image via TWRP

6. Booted system to verify Magisk works (it did - stock kernel + Magisk was fine)

7. Back to TWRP, flashed zero-0.6.4-dumplinger-los-4.4.zip (thinking AnyKernel3 would preserve the Magisk patch)

8. Result: Bootloop again

The confusion:

• I understand zero kernel uses AnyKernel3 (I see the tools/ folder and magiskboot binary inside the zip)
• I know AnyKernel3 is supposed to modify the existing boot partition while preserving modifications (like Magisk)
• But in both scenarios, after zero kernel is installed (whether before or after Magisk), the result is always bootloop
• I've recovered each time by restoring boot from backup, so the device is fine

My questions:

1. Is zero-kernel 0.6.4 compatible with Magisk v30.7 on Android 15 at all?
2. Does zero kernel modify the ramdisk in a way that breaks Magisk?
3. Does zero kernel have built-in KernelSU? (I checked /sys/fs/ksu - no such directory)
4. What is the CORRECT sequence to get root on your kernel? Any official method?

I'm not a kernel developer, just an advanced user trying to get Kali NetHunter working (I have the NetHunter zip but that's a separate issue). Any guidance would save my sanity.

Thank you for your work on zero kernel!
