There are different versions of the Helio P20 as stated many times. The one in the S2 (V1) does NOT support Android 7 at the moment. MediaTek does not provide a SDK/drivers. I agree Umidigi should've mentioned this, but it's really not their fault.

If MediaTek release a SDK i'm sure Umidigi will upgrade the device to Android 7. It's a great device for the price, the only real downside is not having Android 7 (atm..)

What did you do?

Try re-downloading the ROM and flashing it again.

Unfortunately the market is quite not clear about this situation thanks to an intemediate verson of the Helio 2x SoC family.
The Helio P20 (MT6757 at 2.3GHz) was the first one and that SoC is used in UMi Plus E and in UMIDIGI S2. It's used in some other models as well but with LPDDR3 RAM chip.
The Helio P25 (2.6GHz but the case label is not yet known) will be used in UMIDIGI S2 Pro and I don't know any other smartphones already available with that SoC.
However, there's an intermediate SoC version between above the two units above labeled MT6757V and clocked at 2.4GHz. In UMIDIGI's portfolio the Z1, Z1 Pro and S are based on that processor and there are a lot of other brands and models (Doogee Mix, Maze Alpha, Bluboo S1, Samsug Galaxy J7+ etc.) using that processor. Some brands call it Helio P20 (UMIDIGI for example) but most of them advertise it as Helio P25. Samsung has applied the best naming by calling it Helio P25 Lite. Yes, the MT6757V processor is identical to the full power Helio P25 but with a lower clock speed, so it's a light version of the Helio P25 SoC.
Conclusion: Not intentionally but UMIDIGI was misleading when it advertised the Z1, Z1 Pro and S models with Helio P20 since in reality they are based on an underclocked version of the Helio P25. Knowing the information above, you can guess why the Z1, Z1 Pro and S could be released with Android Nougat out of the box but not the S2.

Flashed this update to my S2. Drillisch (PremiumSIM) card.
I can get the "normal" connection to even 4G but still the Roaming icon over the network and no mobile data.

Tried it in both SIM slots. Same behavior. Still can not establish mobile data to Drillisch reseller EPlus/O2 network.

Please go to settings - more - mobile networks - data roaming On.
As your mobile provider is third party network provider (virtual network) you need use data roaming option and "R" icon needs to be above signa notification to warning you that you using roaming option. If you use mobile provider which using his own infrastructure then you will get faster, more stable and without virtual roaming data connection. This is not fault of device or system that "R" icon is indicating.

Please follow this SPFT instruction while you flashing your device.http://community.umidigi.com/thread-11-1-1.html

We strongly recommend follow every step from instruction but to save your data on device you can uncheck user data in SPFT and change "firmware upgrade" to "download".

I have turned data roaming on but it doesn't change anything.

I did use the Download procedure with SPFlashtool.

EDIT:
Will try this new build (1114) when I get home.
