Another major reason ZTE prefer old school 2.5GB system storage/partition is to ensure when updating from stock ROM to another newer stock ROM, the update process will not disturb your media/3rd party apps/data/etc. During OTA update, it will only "disturb" the 2.5GB partition. Hence, your existing/installed apps will not be reset/removed.

If everything is unified, then, after OTA, all your media/3rd pay apps/data/etc will be removed.

Overall, there are pro and cons for 2.5GB partition and unified 8/16/32GB system partition...

I personally prefer the 2.5GB partition so that if anything happened to the 2.5GB system core files, it can be easily recovered/revived without worrying the database for gaming and apps database are lost. We still need to install back these apps but the database is still intact in the internal storage.

Example, you almost complete Asphalt 8 game. Only a few more tracks to go. Suddenly, your Android system files corrupted. Hence, you are required to hard reset/flash back the stock ROM. After hard reset, you realised the Asphalt 8 is totally gone. All your hard work, in-app purchased and the joy to finish the game totally gone and have to start all over again. If there is 2.5GB system storage, you don't lost your record/database. Just re-install back Asphalt 8 and the database/history will be recovered automatically.

But, as of today, lots of apps and games offer cloud storage backup. Meaning, once you have finished one level/stage, it will be automatically backed up to the cloud using your account in the app/games. Therefore, the need for 2.5GB is totally redundant. Unified storage is more preferable...

I have owned LeMoto P780 since last year. It's 8GB variant. Out of the box, it has the 2.5GB system storage. This is during Jelly Bean. But now, LeMoto has released latest ROM that unified 8GB as system storage. But, before OTA update, there is a warning message asking you to do proper backup before OTA. So that, after OTA, you just reinstall back all the apps and restore the back-ups manually ONE-BY-ONE....

So, it's personal choice in the end...

Eh, got cm11 v2 oledi? I assume this is still the unofficial build rite? Has the infrared issue been solved on the new version? If it is, i am tempted to install it ...

I went to the mokee download site but there is nothing to download under nx505j (all release types). Where did you got your rom from?
