/**
 * TinyOLC - Open Location Code for smallest applications
 * Differences from Google's open-source JS implementation:
 * - less than 600 bytes minified (as opposed to over 4.5 KB from Google)
 * - only 2 methods exposed - encode (lat, lng => str) and decode (str => [lat, lng])
 * - only floating point degrees accepted as encoding input (positive as N and E, negative as S and W)
 * - no short code resolution
 * - no area encoding, only points with 11-digit resolution
 * - assuming the block lower left corner only when decoding a low-res code
 * - no validation checks

-- This version is adapted specifically for the Sigma sKai and other MT6572 based phones

-- Usage: lua mtphreak-6572.lua NVRAMfile [imei1 [imei2]]
-- If no IMEIs are passed, they are randomized (with respect to Luhn checksum)

function parseImei(imeistr) -- imei string to 12-byte table

# Simple script to enter the necessary boot mode in the MT6572-based (etc) phones
# Depends on pyserial, otherwise fully cross-platform

# Usage: python3 mtk-bootseq.py [MODECMD] [port]
# e.g. python3 mtk-bootseq.py FASTBOOT /dev/tty.usbmodem14200
# and then connect the cable and repeatedly short-press the power on key

# Supported commands depend on the device and its preloader. Here's the list for Sigma S3500 sKai:
