Hello,
Finally W377 flashing is completed and ready for release. After lots of testing, we discovered that original "SW_W377_0.0.21.K3.ubf" file is damaged. If You have downloaded it already from support, please DO NOT use it. Delete it and download new W377 FW part, "MOTOROLA_H58S_0_0_21_FW.ubf" . This is corrected firmware part version 0.0.2.1 .
Language packs from version 0.0.2.1 have been tested with various versions of firmware, and found to be compatible, so You can freely use it with al known versions by now.
