[MTCD  Android Head Units Q&A] ikerg:
New ROM Update for MTCD

Hi

On the russian forum they have published a new update for MTCD (Non Joying) Sofia Units (as per 20th December 2016)

This update is for Headunits with wifi only (sofia3grw) (not 3G). If updating it on a 3G (sofia3gr) 3G capability will be lost (RIL and BASEBAND), but the headunit will be functional (confirmed on russian forum).

The MCU update is for BONROAD units (be careful. if you dont have any bonroad unit, use ONLY update.zip file and NEVER use the dmcu.img file)

To update on a 3G capable unit some modifications should be performed on updater-script file inside the update.zip (update.zip\META-INF\com\google\android):

First line:

getprop("ro.cpu.type") == "" || getprop("ro.cpu.type") == "sofia3grw" || abort("This package is for "sofia3grw" cpu type; this is a "" + getprop("ro.cpu.type") + "".");

should be modified to:

getprop("ro.cpu.type") == "" || getprop("ro.cpu.type") == "sofia3gr" || abort("This package is for "sofia3gr" cpu type; this is a "" + getprop("ro.cpu.type") + "".");
