The version Newstar (on Qoo10) is selling is China ROM and they said they install Playstore for their customers. So, even if I buy from them, I should still change from China to Global ROM? Will that erase the Google apps they have already installed inside?
@alfy, May I know where did you buy your Mi 5?
Anyone bought directly from Xiaomi official website (on Taobao) or Newstar (sim lim)? Did you run any problems using in Sg?
Let me make it simpler for you to understand.
Export sets...whether you buy from local dealers or direct from Taobao etc.. comes from china and will have china rom installed. However, some dealers may have installed modified(fake) roms with malwares. For a layman, one cannot tell for certain if the phone comes with Fake rom or not. I would still re-flash to original rom from the miui website to be confident it is genuine rom.
I emphasise again:-
I WOULD NOT TRUST THE PRE-INSTALLED ROM THAT CAME WITH THE EXPORT SET!
For re-flashing of rom, you can choose to install China or Global rom.
Global rom is guaranteed to work in Singapore and works just like the set you bought from the local dealers at $619.
China rom in uncertain to work in all networks (3G or 4G etc) and doesn't have PlayStore in it. Even if you can install Playstore separately, you may have problems with the Apps at the later stage. People install China rom only because they feel China rom is updated faster than Global rom and is more current. But China rom requires more tweaking to get it working in Singapore, so is not advised for newbies.
After properly re-flashing of the roms to your phone, subsequent updates will be automatic by OTA (over-the-air) so I recommend that you re-flash IMMEDIATELY to original rom (China or Global rom...up to you) after you received the phone.
I hope this gives you a clearer picture now.
