Acer BeTouch E130 ROM Update Tool (for Linux/OS X) Copyright (c) 2011 Yohanes Nugroho This tool can be used for: - unpacking nb0 file - repacking nb0 file - writing a single package from nb0 file to phone - writing entire nb0 file to phone (NOT TESTED) The protocol for the ROM update is proprietary, and I reverse engineered it by sniffing the USB communication of Rom Update Tool (RUT) for Windows. It may work for other Android phone that uses Windows RUT, but since I can not test it, I am labeling this tool only for use in Acer BeTouch E130.
