Продолжу, добрые люди посоветовали при флешировании "заводской" прошивки под SP FlashTool ставить галочку на Repartition (ранее пробовал без этой галочки - как установлено с CM2MTK по умолчанию).
Так вот прошил, с галкой - результат висим на заставке Explay.
Пробовал форматировать UDA+CASHE с параметром 0, результат тот же- висим
