thankx for reply . i tried it many times but it always says invalid update package. it updates when i update with higher update packege i.e 117 to 122 or 122 to 129 but when i try to update from 129 to 117 it says invalid package

maybe you tried 122, 129 but ROM on the link is official version B120 for g6-u10, so try it with this official. one. It works always regardless of the rom you have at the moment.
Of course you must follow the instruction (dload folder on sdcard and pressing the volumes....)
