Dear waseemrazajafri,
Thanks a million for this detailed tutorial. I had my G2 F320s flashed in to CM 13. Thanks bro!

I'm on 5.0.1 Stock Rom on my F320L
It says here it is not recommended for a bootstack to be flashed if on 5.0.1 Lollipop stock ROM but when I checked on other people, they say to flash the Hybrid Bootstack for the F320L instead even if I'm on 5.0.1? Is it correct? Should I still flash the Hybrid Bootstack?

This bootstack is not important if you came from stock lolipop rom
bootstack will only change your bootloader to kitkat version and nothing else
I'm using f320L too

Hi, i followed ur guide and it worked. Thank u for that!!
But know i have this problem. I flashed rr rom, but rom is not rooted. Magisk app shows non rooted. App came pre installed with rom. So then i installed the zip (magisk 14.0???.zip) through recovery and after reboot i get fast boot mode. I dont know what i Did wrong. I had to flash the whole rom + other steps again to boot after i finally got into recovery, because i didnt installed/flashed the uninstaller. Even if Did, how the hell would i be allowed to use uninstaller after stuck in fast boot mode???? I saw the image file magisk creates through filemanager in recovery, but didnt know how to decrypt/restore. Can u pls help me get the rom rooted? Thanks in advance

for rooting try SuperSU 2.46.zip
and magisk actually patched you boot.img (kernel)
just flash Lambda-Infinito-Beta (kernel) from above Post all will work fine

---

So, if i did all the previous steps and still no root, i just have to flash the kernel to get root acces or what?

kernel is used to boot up rom but unfortunately G2 has its bootloader locked that's why we used bumpped kernel if you flash magisk or SuperSU new version this will patch your ramdisk in kernel
your kernel will no longer bumpped And you will get security error
TRY SuperSU v2.46 I have already tested
or TRy Magisk-v13.1 I have tested this too and found working to get root

Thanks a million dude ,i successfully installed crDroid Rom with this tutorial :good:

ans: yes,you have too install kernel and polymorph, kernel to boot rom otherwise rom will not boot up! and polymorph to use exSD card otherwise card will not work
2. Can I use lamda kernel to install the d802 oreo rom on f320l?
ans : No ,only Android 5.1, 6.0, 7.0 and 7.1 are supported by lamda officially see Q&A section but you can try at your own risk

I've known that in order to install TWRP, the bootloader should be unlocked. I successfully installed TWRP on my f320l.
And then, should I use the bumped kernel to install Lineage OS on my device?

Hello Sir, Sorry for the late reply.
My Device is F320l and downloaded rom is for D802..
I'm attaching the script files of lineageos 15.1 which i have edited with notepad++ but at flashing it says invalid zip format.
I know lamba kernel only support upto nougat but lineageos14.1 is not available anymore to download that's why i am using this .
