It goes like this:
As we know, there are two Coolpad F1 versions - one is TD-SCDMA (China 3G network), the other is WCDMA (EU compatible 3G network)
TD-SCDMA was released first so it has higher rom version number - now it's 086
WCDMA is at 029 now
These factory rom releases are official and arrive at phone as OTA upgrades.
Smart guy (or guys) from China take that roms off their phones and make them flashable thru CWM/TWRP recovery,
with some editing (removing bloatware and adding stuff)
Good thing is that TD-SCDMA rom version can be used on our phone, too (with minor changes)
since all of the difference is in modem software and that can be copied from one rom to another.
In conclusion and taking the above stuff in account - we have TWO official roms. One with high number 08x
and another with low - 02x
To make it more clear - pure official version comes only thru OTA (wifi/3G) upgrade
Everything else that you download and flash thru recovery is altered - more or less...
P.S. to correct myself - pure official versions can be installed thru Flash Tool or CPB software, too
but it is more complicated and I wouldn't recommend that except for the phone unbrick purpose
