Is this phone available at KL, Low Yatt Plaza ? unofficially, please can anyone confirm ?

Thanks a lot for the help but i'm visiting KL as a tourist and I will only have access to Low Yat Plaza because of busy schedule, i need to make it certain whether third party vendors located inside the low yat do have Redmi note 3 available ? can any one confirm

Guys, I have the redmi note 3 vendor version with miui 7.1.1.1 stable, i'm sure it's not the official one, how to get the stock rom ? if i flash it there's a chance i can brick it since i'm not well versed with tutorial and how to do it however there's another way to update... which is it on xiaomi's miui site that says to simply download the rom and put in ‘downloaded_rom’ in the internal storage of your device. and then update from device.....

any one can confirm if doing this will brick the device or flashing it from zero is the only way to go
