I did solve the problem with the GSM signal.
As you can see on the screenshot IMEI lost after format by sp flash, no assigned IMEI is not allowed to connect to the GSM network. After assigning the IMEI SIM1 and SIM2 signal came back and everything is ok.

Card reading slot SIM1 and SIM2
- Located GSM operator
- Sees preferred networks
-No signal
Defective antenna gsm?
Error RoM? V (does not work after the last update reader finger) I read about it and I know that the fault of the software is it possible that this has something to do with GSM coverage? I do not know whether to wait for an update or replace the antenna.

If someone had a similar case? I do not know what to do with the phone I installed a new version of ROM 20,161,017th or it may be the cause of the lack of (the loss of GSM signal). ?

Please Help topic. I do not know if this 20161017 ROM is the reason for the loss of GSM signal or wine equipment. Preferred network detects hand was adding GSM operators but no signal. I do not know whether to wait for new updates which will solve the problem.

Since you're the only one reporting loss of GPS signal in relation to latest ROM update, I strongly believe these are not related. More likely a hardware problem, if anything. To eliminate a bad update - Have you flashed latest ROM using the SP Flash Tool? Seems like a more reliable method than OTA updates.

update done automatically, I did not use SP Flash, how can I check if this is the antenna GSM?

HI there.
Does Umi super support 4g on both Sims?
I have 2 sims in atm and one of them is showing that only 2g is available (not very usefull is you have 3 uk network which doesn't use 2g any longer)
Is there any way to set up both sims to use 3g/4g at the same time?

Nope; 2G on one, 3/4G on the other SIM. If I've read correctly, the Nougat ROM for UMi Plus allows for 3/4G on both SIM cards simultaneously, so maybe we'll get this for UMi Super too?
