I have an old S4 mini which is a different model from the one in the supported devices list - SCH-I435, versus GT-I9192 in the list. According to phonedb.net, the two are virtually identical. They use the same processor. The I435 has one SIM and 16 GB ROM, vs.2 SIMs and 8 GB in the 9192. The I435 is rooted, if that matters.
Given how similar the two models are, should I be able to install /e/ OS on my I435 using the instructions for the 9192?
