    Your question indicates some sort of confusion between available versions.

    Depending on your hardware, you must flash either a TD or a WCDMA version.

    For each hardware version, TD or WCDMA, you have the option to flash an official Chinese/English version or a multilanguage one.

    There is no JHCNAL5.0 version. There is a JHACNAL5.0 TD version and a JHBCNAL5.0 WCDMA version.

    Also, there is no JHACNBA15.0 version. The latest official TD version is JHACNBA13.0, while the latest official WCDMA version is JHBCNBD15.0. The latest multilanguage TD version is JHACNBD15.0, while the latest multilanguage WCDMA version is JHBCNBD15.0.

    The first link you provided refers to a multilanguage version, while the second one refers to an official Chinese/English version.

    You can visit http://xiaomi.eu/community/forums/miui-weekly-rom-releases.103/ to download any available multilanguage version, including the latest one, for both the TD and WCDMA hardware versions.

    When you visit the official http://en.miui.com/download-82.html download page, the TD hardware version is selected by default. You can click on WCDMA to change the selected hardware version. There are also some customized Taiwan, HK and Singapore WCDMA versions. For each hardware version, under Stable ROM, the Full ROM pack option is selected by default, where you can download the latest available official version. You can also select the Older versions option, where you can download all previous official versions.

    Each newer version is supposedly better than any previous version, since this is the purpose of each newer release. In each newer version most known bugs are resolved, but there may be some new ones induced. There also exist some minor hardware revisions of the phones, so sometimes some specific software version seems to work better with a particular device.

    It is always safe to install the latest version, whether the official or the multilanguage one, since you can safely revert to any older one. Some phone settings are not interchangeable between totally different software versions, so if you experience serious problems after an update, you may also have to factory reset the phone. This can happen if you change between official and multilanguage versions and especially when you roll back to previous versions. You can always make a MIUI backup before factory resetting, to be able to restore any previously customized settings later. If you have any crucial application customized data, it would be wise to keep an extra copy of your MIUI backup in an external microSD card, to be on the safe side in the case you accidentally fully format your device, or your device gets corrupted or being replaced for whatever reason.

    If you are currently happy with the version you are using, you may stick with it for as long as it makes you happy, but I always recommend that you upgrade to the latest multilanguage version, even if you cannot tell the difference, because there can be signal or battery optimizations.

    What I can say is that the best rom for Redmi 1 WCDMA is V5.
    From this onwards is just crap with new add-ons to disguise the smell lol
    This 15.0.0 has the worst camera ever. I have taken about 15 exterior photos today and had to delete all. They were just disgusting

    Out of interest, my phone MIUI version is JHACNAH.50

    Someone suggested to me that this is no good in Australia, but my phone seems to be working fine?


    (I need to get Google play and multi-language pack installed though)

    If your phone has a JHA... rom installed, then it must probably be a TD-SCDMA hardware version, meaning that 3G features are not working outside of China. Your phone may seem to work fine, but you are probably using only 2G GSM Australian networks, not being able to use any 3G W-CDMA Australian networks.

    JHA... suggests a TD-SCDMA version, while JHB... suggests a W-CDMA version. Since there are fundamental hardware differences between TD-SCDMA and W-CDMA, it would be probably not wise to install a W-CDMA rom on a TD-SCDMA device and vice versa.
