Hi I have run into some significant issues in getting Miuiandroid updates to work on the M1 C1 (CDMA) that I just purchased. Here are a few observations: 1. The stock Miuiandroid update for the C1 will not work on this phone in its current format. I tried many times to update from 2.3.5v to the latest ICS ROM (2.5.11). 2. I finally got the update to work by modifying the script file contained at META-INFO/com/google/android/updater-script. Specifically, in the first line of code, I had to make the following changes: 1. getprop("ro.product.device") == "mione_plus" TO getprop("ro.product.device") == "mione_plus_cdma" AND 2. getprop("ro.build.product") == "mione_plus" TO getprop("ro.product.device") == "mione_plus_cdma" Then had to wipe data / cache / update partitions and it worked from running updater within the 2.3.5v ROM to install. Subsequently, the latest ROM (2.5.11 ICS) was on System 2 and 2.3.5v (GB) remains on System 1. I tried to run a subsequent update of System 2 to 2.5.18 (ICS) and found that it only worked following the revisions to the script outlined above, and the update would only work for some reason from 2.3.5v (GB) on System 1). I have not been able to update System 1 to ICS under any scenario.
