Kernel 4.19 not booting may Update

[MelihAdalet]

My S20FE is not booting in the May version of Andrew´s Pixel OS does Someone have found a fix for this. Yes, i know that Google changed AOSP and booting on some devices can´t be possible. But, i have hope that it works because in the changelog it said that there was fixes for kernels and something else so that older devices still can boot.

Kernel 4.19 isn't that old yet. Fixes were for 4.14 and older

On a Teclast T40s device with kernel 4.19 I had bootloops with latest Elixir 13/14 GSI but PixelOS worked fine (minus Bluetooth)

nickpapoutsis what kernel exactly like i have 4.19.87-gaab7192739b3-dirty (lineage21kernel) maybe you have a newer version of that kernel or it maybe happening because of the exynos processor i tried Elixir 14 too and had bootloops too

[MelihAdalet]

YESSSSS MATES i got it fixing i always tried to flash it with TWRP but you need to flash the gsi with Fastboot

here the commands i used mates

fastboot erase system

fastboot flash system system.img

fastboot -w

fastboot reboot

nick it will probably work with Elixir too so if you want Elixir go for it

ehem Andrew is it normal for the May version to take so long to load bc since i flashed the gsi its only showing the google logo and is sometimes restarting

Get logcat adb logcat >logcat.log And I'd recommend you to flash data through recovery instead of doing fastboot -w

Just tried this gsi on an POCO X3 PRO and it worked fine i don´t know why its not working on the s20 fe also tried adb logcat and its sayin /system/bin/sh: logcat: inaccessible or not found

also just sayin maybe it helps since you released the qpr 2 builds it didn´t boot too

just realised that my kernel is not supporting qpr2 a14 builds so i might try kernel upstreaming

My device has an MT8183

Got same issue on Galaxy Tab S7 plus

[MelihAdalet]

Mates i believe i found a fix, i just need to test it.

Its a Kernel Upstream "https://github.com/maosith/msm-4.19-meow/releases". i hope it works

[MelihAdalet]

mates it works you just need to upstream the kernel sadly the meow kernel isn't availiable on the exynos version yet but it will.

How do i come to the conclusion that you need to upstream the kernel? on the s20 fe page of xda is a lineage 21 version with this kernel: 4.19.87-gaab7192739b3-dirtyand its compatible with qpr 2 (the lineage version is litteraly qpr2)

the normal stock rom has this kernel 4.19.87-27231340 which is not compatible with qpr 2 a14 i think. to support my argument: the lineage version has a custom kernel (4.19.87-gaab7192739b3-dirty) and it also boots in qpr2.

if you have questions ask them i will try to answer
