Unregistered SIM, phone not working

[fred56]

Hello UBports community !
I recently managed to install UT 16.04 on my Aquaris E5 (Ubuntu Edition).
But I can not make my phone work nor make calls: he tells me that my SIM card is not registered.
But he detected it and accepted my SIM PIN.
I had no problem of this kind with my previous system (the latest Canonical Ubuntu Touch).
When I go to "Cellular Parameters / Carrier & APN / Carier", the operator search is automatically performed, mine is found (Free) but it refuses me to select it. When I return to "Carrier & APN", the entry "Carrier" remains at "None".
I suspect a write access problem, but on which device or file?
Another strange thing that can be linked: it does not save the password of my WiFi network and creates a new entry in the list of networks every time I leave it.
Does anyone have an idea of ​​the source of these problems?

Look to see if you have an imei number.
This is shows in android, as nvram error x 10
This usually happens if you use the flash _tool
and use the ' format all+ download ' setting.

Try searching ubports

@Marathon2422 : Right ! I have no IMEI number (None,None) and the serial number is 0123456789ABCDEF.
I have used flash_tool with "format all+dowload"
searching UBports forum for a solution to write the IMEI (I got the number on the box)

Try viewing,“ xxx.skyneel.com” and search for, nvram error. ( replace x with www)
This should explain it for you

I have looked at xxx.skyneel.com and found on it two methods to restore the IMEI on a phone, but none of these works on mine :
1- by installing MobileUncle apps, but its is an android apps so I cant install it on an ubuntu touch phone.
2- by entering the engineering mode by tapping code * # * # 3646633 # * # * or *#4634#, but in my case nothing happens
So what could I try now ?
should I install an Android system on my aquaris E5 HD and then install MobileUncle apps ?
but how to do it ?
