Hello Chris, and thank you for the help.

I created the file that you said, but when I try to copy into /android/data/nvram/md/NVRAM/NVD_IMEI/, it says permission denied, how can I fix that?

EDIT: ok, I got it working now. It works! Thank you for the help Chris!

Its not UBports at all but may help in the reflash to Ubuntu touch as that seems to be where the imei is vanishing and seems to be something in SP Flash Tool settings. Lets hope the welcome install group can help.

I actually tried those instructions already. Before finding UBports I was following that tutorial. But in which part there''s the IMEI problem? I didn't see it there.

@ayatachibana Try the welcome and install group at https://t.me/WelcomePlus They may have more info for you.
Just to clarify, you had imei on Android and you have no Imei after reinstalling original Ubuntu Touch then UBports Ubuntu Touch.
As an aside sometimes switching to the dev channel in update settings, and installing the update brings back mobile data, as does switching areoplane mode on and off. But maybe not if theres no imei. Can you make normal calls ?
P.S.
Have re- read original post and it seems to say
1, you can recover the imei from Android but not UBports at present.
2, You may well have to get in touch with BQ for them to help you out.
I don't suppose you have any of the original packaging hidden away do you : ) If not it looks like reflash android, sort out imei. Then reflash Ubuntu Touch followed by UBports Ubuntu Touch. I hope I'm wrong and good luck.

Hello, and thank you for the answer.
To answer your questions:

• I tried changing to the developer channel and turning on and off the airplane mode, no success
• I can't make any calls, Ubuntu says that my my cellular data (in the notifications) is refused or denied, something like that
• I still have all the original boxes and papers, so I still know my IMEI, and I can add it while Android instead installed
• I will try the procedures that you said when I got some time. I will return with the results

Also, thank you for the link of the telegram group. I also asked my question there.

Hello everyone.

I have a Aquaris E4.5, it came with Ubuntu touch.
But I had to use Android for some time, so I installed Android on it.

Today, I could successfully install the UBports Ubuntu Touch, and it worked really well. But the only problem is that the cellular data doesn't work because there's no IMEI.

I followed this tutorial: https://forums.ubports.com/topic/832/lost-or-deleted-imei-number/9
(see andromeda's post)

I could change the IMEI with Android, but when I have to install the UBports Ubuntu touch, it tells me to first install the older version of the Ubuntu touch (https://docs.ubports.com/en/latest/userguide/install.html#install-on-legacy-android-devices)

But the problem is that when I install the older version of the Ubuntu touch, the IMEI is lost again, and I can't find a way to change it inside of Ubuntu Touch.

So, is there any way to make the IMEI not erasable? Or maybe change the IMEI inside Ubuntu Touch?

Thank you.
