I tried flashing this to an old device (S4 GT-i9506). not my daily.
Clean System, Data, Cache & InternalSD (installed from a small external SD)
When I tried flashing MindTheGApps, it failed with error 1 (see attachment). But I still attempted to boot to system, but it sat on the boot animation for >20m. So, that was without GApps
I then tried BiTGApps, although that flashed without error, it also stayed on the boot animation.
Lastly I tried NikGapps, and that flashed without error, but it also was stuck on the boot animation (see attached).
I am guessing that device has the wrong modem and bootloader? Which combination is it expecting? would that stop it from booting? or is there something else in the logs that hint and why my device wont boot?
