Yes, it did. It is also successfull with 5.0 ROW version posted here http://lenovo-forums.ru/topic/14572-lenovo-tab-2-a7-10-%D0%BF%D1%80%D0%BE%D1%88%D0%B8%D0%B2%D0%BA%D0%B0-t2-a7-10f-s54-150801-row/. But although these are European firmware files, installed firmware always is Chinese version. Edit: Success! I installed above mentioned version (5.0) with firmware upgrade selected in SP flash tool on the top of 4.4 which was installed on the tablet. Code for software info version is ####5993# and it showed something like T2-A7-10F_S54_150801-not set. Code worked on this 5.0 version, but not on 4.4. Code for Lenovo Tab2 A7 10 is ####682#, ####6020# doesn't work.
