I've got another two ideas...
1. Is there any /misc partition on the sensation ? where is the CID and other basic config parameters are stored ?
i've seen HERE
that /misc partition:
...contains miscellaneous system settings in form of on/off switches. These settings may include CID (Carrier or Region ID), USB configuration and certain hardware settings etc
thus I wonder if during RUU install,are /misc and similar partitions being clear ( then they update with new info ) ?
is there any chance the RUU update does NOT clear/update ALL of the device partitions. ( which may held config files of the device ).
2. Is there any way to run FASTBOOT commands NOT through USB ?
can the terminal inside TWRP recovery used for that ?
can I make some sort of a PG58IMG.ZIP file which contains only a fastboot commands to run ?
