Hi aibd, thank you for your response.
The Wifi-on-setting of APN I did, but without success. And I used two options of APN instruction - both did not worked.
But I need to clarifiy: my SIM card services do not work at all. And on the APN site is written: “Die Einstellungen für den Zugangspunkt sind für diesen Nutzer nicht verfügbar” Translated: “The settings for the accesspoint are not available for this user”
And beside the SIM-Icon is written “Nur Notrufe (SIM-Karte ist gesperrt.)” Translated: “Only Emergency calls (SIM card is locked)”
Hmmm … I think those are fairly standard messages for a SIM which has no connection to your carrier (although more common are the cases I linked with partial connection to the carrier airwaves).
What does your carrier say about this? (He is collecting your subscription for zero service!) I hope your carrier is not one which makes a big charge for this type of call … if so perhaps you can email.
Currently many carriers are changing APN with tiny changes due to changing technologies worldwide. If doing changes manually you have to be sure to have the latest published data.
Did you ask for this to be done? As in “Please send the APN to my device”.
I see you have a difficulty when you cannot get a line ( ! ) but the issue is not a defective SIM card, but it is not registered within the /e/ device.
I suggest that, when you speak to the carrier, you need to explain the card is on “Emergency calls only”. The person who takes the call should be able to tell that the SIM card is “live” and be able push the APN to that device.
(Of course there is always the possibility that is is not APN issue but that the SIM has not been accepted/recognised at all by the device, BUT in these circumstances I would expect a different error message ( NO SIM ) and you could not make Emergency calls.)
Previously the device was running with the OS /e/ 0.23
Do you think this should work, although my SIM is locked and the OS did not pushed me for the PIN of my SIM?
Mmh… the problem is: The number of the carrier I can only phone using a Alditalknumber… - so I can not have the SIM at the same time in my phone and the same time phoning the carrier. But I can look, if I find another person with the same carrier.
I am not sure: Because in the Brand-New-Scenario the phone would push me to enter the PIN of the SIM. And in my case this did not happen. And the other thing is, that I am not able to create manually APNs.
As a matter of interest I searched this list for my (supermarket, cut price) carrier. I find 3 matching lines. Interesting too that at first glance they are incorrect (out of date)! This explains why, in my case, if I format the data partition, I have to ring the carrier and ask them to push the APN to the device.
It is certainly unusual to see zero contact with the carrier airwaves! I fully see the difficulties, but I do not read that you succeeded in getting the carrier to push the APN direct to the device.
Thank you. I tested the APN with these dates another time, but after “save” the APN I wrote disappears…
Yeah, but in your case your phone also not asked you for the PIN of the SIM card and did you have “only emergency calls” also?
At the moment I phoned another time my carrier. She said, that she can not do anything, since I have no connection to the mobile network, except emergency calls. I neither can recieve SMS. She asked me, if my phone has a SIM-lock. I think that should not be in /e/ and before the upgrade my SIM worked fine.
Factory reset – the most extreme as your data will be lost, so you would have to ensure a backup first. A TWRP data backup would be useful in this case, but I always like a double backup of important stuff. https://dl.twrp.me/osprey/ exists but your device may have the /e/ Recovery.
Carrying out a downgrade of /e/ version should be no more risk than the update. I would expect the downgrade to fairly painless. You should not need to delete data.
I do not know if you have /e/ Recovery or TWRP.
TWRP allows you to install the /e/ image https://images.ecloud.global/dev/osprey/ by downloading it and put it in an accessible place on the device, internal storage or SD card. Or copy to SD card from PC. I am not certain if /e/ Recovery will do this.
Using the sideload method, in brief it would involve
On the device
Enable usb debugging, https://doc.e.foundation/pages/enable-usb-debugging.html
Boot into Recovery mode – will look and feel different comparing TWRP and /e/ Recovery.
Select the ART/Dalvic, Cache and System partitions to be wiped and then Swipe to Wipe
select Advanced, ADB Sideload …
… ensure you have connection with PC, see below …
then Swipe to begin sideload.
On the connected PC which should have adb enabled https://doc.e.foundation/pages/install-adb-window (this page is available for Windows and Linux). Do the first command below simply to ensure you have contact with the device, nothing happens other than check you have contact and gave authorisation to the PC to debug. Depending on your adb install method you might prefix the commands with ./
