3. Requirement

• Samsung Galaxy J4, with bootloader unlocked
• Official TWRP 3.4 (CLICK HERE)
• Any GSI ROM A64 A/B installed (Search for the tutorial)
• Magisk (Optional, if you want root)

4. Installation Steps

• Boot Into Recovery
• Flash as usual
• If you ever flash Magisk before, it got deleted. Reflash magisk or keep unrooted, that's up to you
• Reboot

If you face the 'there is a problem with your device' (AOSP GSI), simply ignore it :)

5. Bugs

You tell me :) If you want to report, please send me last_kmsg from /proc and logcat when doing the bug. Syslog is helpful too.

6. FAQ

A: Does my data will going to deleted when installing this kernel?
B: NO! The installer script is just replacing boot and dtbo partition, NOT DATA PARTITION. So data will safe.

A: Keep getting bootloop or infinity boot (enter the screen and then goes back to boot animation)!
B: Do you flash in GSI? What GSI you use? And you sure you flash this after Android 10 update, so the Q vendor is installed, not P?

A: You f*cking fake!! This is broken kernel!!
B: Dude, I tested this kernel my self! And it works properly. You want proof? Go to Post 3!!

A: Great! How I can help you? By donating?
B: See number 7 below

7. Donate

If you feel this kernel is helpful, and want to help me build by donating, here is the answer : Don't donate to me, donate to other people that more need donation. I'm not being rude, or don't want to be helped, or whatever. This kernel is builded in my free time, so I don't do this for job, but just my hobby :)

8. Source

My source is freely used for anyone. You can fork it, clone it, even build it without my permission. But, if you want to rebuild kernel, add other features, and share to somewhere, please add my credit! Atleast my XDA username, 'source forked from RedLine', or anything! It will be very appreciated :)
