I haven't tested this app, but I can confirm DriveDroid is still working well on LOS 18 and i9505
Thank you very much, works even better becouse not only boot but inside windows too. One thing, is it possible to mount iso from sd card formated as external in this rom? I've got error when try it. From internal memory works great. Btw what is max sd card i can use in this rom?

Can I use bank apps with magisk in this version?
That depends on the specific app. You should do an internet search for the combination of android version + magisk + your app. For sure, you'll find discussions about the banking app not working and (hopefully) someone who got it running by doing very special things. I got my app working by using magisk hide and installing an additional app: Airfrozen.

Got it, I'll have to test builds from 6 to 10

Is anyone else having a problem installing version 6? It just boots back into recovery after the first boot. I'm pretty sure I installed it properly, because I installed version 5 no problem, but trying to install version 6 would go back to recovery, and now installing version 5 would go back to recovery too, for whatever reason. Probably something wrong with how I'm installing it, but I checked the instructions countless times and still not working.

... version 6? It just boots back into recovery after the first boot...
Have you checked @Retrial's S4 Unified Guides & Collection? Link is 'hidden' in first post. In S4 Unified Guides & Collection, search for 'CLEAN INSTALL CUSTOM ROM' and follow these steps. That should work. If not, you could go back to stock rom (you can find instructions how to do that also in S4 Unified Guides & Collection). In both cases you'll loose your data on your phone, so you should make a backup of your important data before.

I've never read the Unified Guides but I know how to clean install a custom rom by heart. I've already flashed the stock rom and it still didn't work. I have a suspicion that it's caused by the fact that I forgot that I used a Magisk boot image that's meant to be used on version 5 on version 6, but I can't be sure, because I flashed the rom and GApps multiple times and still not booting into the system.

Sometimes, it's neccessary to wipe cache / dalvik in stock recovery after going back to stock

Someone reminded me that I'm using a Magisk boot image from version 5 that I'm flashing onto version 6, so I flashed the stock rom, then installed TWRP, then flashed the custom rom and GApps without Magisk, but it's still not booting into the system ;-;

I don't have a lot of options now.
