This Rom is an update for Stock Rom for all GSM non Verizon users with more new locales and relative languages.
The Rom is available for ICS and for JB. The Rom is odexed.

The Mentor's Rom updates the Droid 4 Stock Rom optimizing the GSM, removing all the settings of the Global Network (cdma and lte) unnecessary for the use of this terminal outsite the US, fully enabling functionality blocked by Verizon, removing all unnecessary Verizon components and installing the support for a lot of languages and localizations.

The rom is an update for the official rom and must be installed with Safestrap on the stock rom.

Surely the best gsm rom for Motorola Droid 4 xt894.

Risk of briking:
no one: during installation the installer checks everything is ok and stop installation in case of problem

Advice post-installation:
- ATTENTION: the version for JB automatically performs a factory reset at first install
- After installing the ROM to optimize the GSM go into the hidden menu Testing typing the code *#*#4636#*#* and you have to make sure that the rom has set and otherwise you have to set: Phone info -> Set prefered network type -> GSM auto (PRL)
- After installing the Rom you can uninstall Safestrap and have a full working stock rom for GSM/UMTS in your locale. To remove SafeStrap you have to reinstall the app, then you have to uninstall the recovery and finally you can remove SafeStrap
