After I completed the installation on my Sony Xperia XA2 and inserted the SIM card and rebooted the device.
After reboot I noticed a triangle icon with a small cross inside.
I open the default caller app and dialed a number and the call button and it states:
Radio off
Then it shows the following message:
Turn off airplane mode to make a call.
But in Settings the airplane mode is turned off, WIFI and Bluetooth is working fine as well and E OS can see my SIM card and see the TELCO Operator name etc.
I changed the SIM card from another TELCO Operator and the same problem. It sees the name of the Operator in the Settings, WIFI works, Airplane mode is off but when I try to make a call it complains about airplane mode.
DonÂŽt know if this matches your case, but i got a similar issue after last time rebooting my device (which works fine after all with /e/). In my case it was the settings for âmobile data usageâ which suddenly was turned off. So maybe you can try to search for all those settings regarding LTE/5G mobile data and check if they are turned off.
Sure you reinstated Android 9, 50.2.A�
And did you carry out the copy-partitions step on the eOS install?
Were you on Sailfish prior to RTS (return to stock) with emma?
The little cross is to indicate mobile data is turned off btw.
Yes and when I try to turn on âradio mobileâ it allows it, but it does not really turn on and when I leave the screen and come back it is turned-off again. It does not let me turn-on the mobile network. I tried to change the settings with no effect. It returns them back to where they where after I close and re-open the screen.
Yes, they return to the previous once, like if they are not stored. Selecting or making changes there do not become permanent. When you return to the same screen they are back as they where. It seems to be disabled.
So you installed Android 9 using emma. 50.2.A etc is the number allocated to Android 9. Android 8 would be 50.1.A something (as indicated in the XDA link you posted.You would be achieving the same thing by installing 9 via emma)
You can double check the firmware version with phone in fastboot mode, in terminal enter fastboot getvar all
Sixth line down in the output look for âversion-basebandâ, what do you see?
Iâm sorry I donât know what the problem could be, other than to think itâs a broken install with the sonyâs emma or a problem with the phone itself; but I guess you already tested the sim with android before flashing e?
Iâve flashed the XA2 back to stock with emma many times but there was one occasion where it didnât work properly; I couldnât turn on wifi after booting. This isnât going to help you but I relate the story just for what itâs worth. This was Feb last year, phone was on sailfish and I did RTS with emma. When wifi didnât turn on I ran it with emma again. Same problem. Flashed it with newflasher and android 9, same problem. Not knowing what else to do I then flashed the e pie test-build and it worked and the phone was alright after that. Still donât understand it.
As part of the latest testing round I returned my XA2 to stock android 9 (newflasher) before installing e-0.21-r and Iâm now experiencing the same issue. This will be reported in the testing channel and Iâll probably make out a bug report if one does not exist already.
Previously I had tested up to and including 0.19-q and 0.19-r without experiencing this problem.
0.21-r currently in testing by volunteers. 0.21-q will follow.
Follow the weekly updates for testing status and look at the testing category for more info.
If I get any useful feedback relevant to this topic I will share it.
It turns out that there are no issues with phone calls due to the eOS versions mentioned above. Whilst I cannot pinpoint 100% what was going wrong I can say that if one follows the installation instructions exactly a good result should follow.
In brief (for a previously unlocked device) that would be:
Return device to stock android 9
Boot up, test calls etc, take a note of APN if one wishes
Turn on usb debugging
Plug device to pc, reboot bootloader
Flash boot with recovery-e
Power off device (unplug), manual reboot recovery*
Plug device to pc
In recovery
Sideload copy-partitions zip and allow to complete
Factory reset/format data
Set up adb sidelaod with Apply Update
Sideload eOS zip
Reboot
*This step is missing in e installation instructions.
