Sorry for english, i'm from Italy
I have a star S7100, with original firmware e1901_v77_jbla668_9p017_20121120.
it is same S7180 but it have only 512mb of ram .
i have just flash it with firmware of S7180 and all work!!!
So i have make this::
Cwm Recovery, ( you just have this http://www.mediafire.com/download.php?8ryinnrrttg1one
Root file by CWM http://www.mediafire.com/download.php?v8qhqfy7ngbyt3z
TWRP Recovery , a new modded recovery with more options http://www.mediafire.com/download.php?2mg82lnlgd17pyy
Alternative Unsecure boot image ( for rooting and backup) http://www.mediafire.com/download.php?bg22l4b5bcncblc
EBR1 alternative file for have 2,5gb for app http://www.mediafire.com/download.php?wffe44l2lht36ie ( you must do a full wipe first and before flashing it by CWM so you make a backup first.)
You can try to flash this files BUT YOU DON'T FLASH NEVER PRELOADER AND DSP_BL!!! so if somethings go bad... you can flash again your firmware with a stock firmware.
