UMIZERO ROM (KitKat, Playstore &Pre-rooted) Full ROM for SP Flash Tool
This ROM comes directly from UMI for reviewers - officially not released yet by them.

You can NOT use CWM to flash this, ONLY for SP Flash Tool! Follow the steps 100% in the bottom of the page!
If you are not an experienced SP Flash Tool user, then don't do it. You flash at your own risk, if something goes wrong it can brick the phone –you have been warned. Therefore ONLY for experienced users! If your new to this, wait for UMI official to release and update for SD card, probably they are going to release it in Januar 2015.

Hardware : MT6592trubo
Model : UMI ZERO
Build number : UMIZERO.V3.02
Build date UTC : 20141231-044242
Android v : 4.4.2
Baseband v: MOLY.WR8.W1315.MD.WG.MP.V35.P3, 2014/10/21 12:48
Kernel v : 3.4.67 (liujia@liujia-ubuntu) (gcc version 4.7 (GCC) ) #1 SMP Wed Dec 31 12:39:42 CST 2014

If you flash this on a wrong phone you do it at your own risk!
I take no responsibilty for anything!
Untick preloader i SP Flash Tool before you flash, I recommend not to flash the preloader.
When you connect your phone into the computer via USB data cable to flash, hold Vol down! on the phone.

IMEI numbers
Please write down your IMEIs before you flash. If you after the flash have lost the IMEIs, use this code
*#*#6865#*#* and re-enter the IMEIs again.

Questions and Answers:
Q: From where do these ROMs come from?
A: Directly from UMI, but they release them only for selected testers, as they are only Beta.

Q: Can I flash back from 3.02 Beta to 3.01 Stock?
A: Yes you can flash to what version you want, and as many times you will, there are no limits

Q: Are there any risk trying 3.02 Beta?
A: No not really, because you can always flash black 3.01 Stock again. Only risk is if the Flash tool crashes or something goes seriously wrong while flashing. But should not happen if you follow the instructions.

      OK I get what you mean now, but what I have done is to seperate them in final and beta roms. Next time there is another update to the final ROM I will add it to the existing post –and only make a new post if the Android version changes. Hope your happy then!

      You can update via SD, but not with this firmware here, this one here is only meant for SP Flash Tool.
      If you want to update via SD, you need to wait for UMI releasing an update for SD. I guess in Januar 2015 maybe they will release one.
