It is software version 1.54.401.10.
I flashed to the elementalx kernel and put on a TWRP recovery.
I am able to download the update but when it installs, it just goes into recovery.
I made a backup of the original kernel a few months ago however it doesn't seem to be on my phone anymore.
When I look for stock kernels they all seem to be different versions than my device.
Can someone give me a bit of advice?
There are numerous guides for other versions but none mentions my software version.
