Welcome to this thread. Here you can find the Stock ROMS officially released by ZOLO
Android Version: 4.2.2
Stock ROM in .img format(For flashing via SP Flash tool)
Stock ROM in .zip format(For Stock recovery flashing)
Note: This is my personal message to you. The stock ROMS above are really bad and
causes many problems. So install these custom ROMs(for warranty purpose) only if you are taking your
Q900 to service centre for any repairs. For daily life use MIUI and my custom stock ROM since they
are really stable and faster.
