Help me find a modified firmware for S-Tell (Ctyon) M200 - Android Q&A, Help & Troubleshooting

Good day! I'm from Ukraine. Son bought a smartphone S-Tell(Ctyon)M200(white). Works fine, but the games throws out immediately or within 1 minute. Searching for solutions to this problem in many forums around the world. Found a solution: a) Not enough RAM or b) You need to reinstall the firmware. My steps: Using programs Mtk_Droid_Tools and SP_Flash_Too I did patched boot.img and CWM "cwm5504_B63M_120507_recovery.zip"(h t t p : / /forum.china-iphone.ru/viewtopic.php?p=714115#p714115). I got root. With the help of the program RAM-EXPANDER.apk wanted to install additional RAM without affecting the data on the SD map(16Gb). To avoid problems, I installed the program MemoryInfo+&+Swapfile+Check.apk. As shown by the program test, I can not increase RAM due to system parameters smartphone. It remains to establish a modified firmware. But I did not find her. In Google there are only advertising smartphone S-Tell. Please help find the firmware for this smartphone or at least where to look.
Here is information about its data from different sources.
