SOLVED: Root 4.22 SGP311 10.31.C.0.136
edit: easy rooting toolkit with method 0 (goroh-kun) worked
Unfortunately in my excitement I updated to 4.22
I am wondering if there is a root method which works for my device.
ADB drivers installed and it shows up under adb devices
I hate tried doomlord v17, easy rooting toolkit v101, and bin4ary v33
none of them have worked so far
doomlord says i need to remap pfn_range_addresses
others either hang or fail outright.
