[XDA Assist] phiyuku:
I have been unable to get past the TWRP splash screen. I have been able to get adb access luckily though as well as fastboot. This is LG L90 D415 variant. I have tried flashing CWM recovery as well as reflash TWRP and it is not working. Fastboot honestly doesn't seem like it is doing anything considering I have also reflashed laf.img which should bring back software upgrade mode and disable fastboot.

Dmesg is just a bunch of:

<3>[ 70.115065 / 01-01 01:30:19.409] mmc0: cache flush timeout

the recovery log shows:
