Another update with some good news: the phone is finally able to boot! Here’s what is working correctly:
- Display and touchscreen
- Speaker
- Microphone
- WiFi
Here are the problems I encounter:
-
The battery level is always 50%, and even when the phone is plugged it reads “Connected, not charging”. The phone sometimes turns off when I unplug it so for now I am using it connected to a power bank. I tried to dial *#*#66#*#* as mentioned here but this didn’t show any menu. As my phone is under LOS is also tried to dial *#*#197328640#*#* (found on this Reddit post) but this didn’t work either. The *#*#4636#*#* (from this other Reddit post) did make a menu appear, but it only has Phone information (mainly network settings), Usage statistics and Wifi Information menus, so nothing to check the battery health.

I cannot send/receive SMS and phone calls. On the lock screen the top bar shows “No SIM card” (although during booting it asks me for my SIM PIN and shows the correct network provider). When I try to make a call I get a “Turn off aeroplane mode” message and under the name of the contact I selected is written “Radio off”. When I go to Settings > Network and Internet, under Calls and SMS it is written " (Temporarily unavailable).
However, this might be due to my SIM rather to the phone: I had my SIM cut from standard to nano size in a shop, and when I put it in the first time it didn’t work right away, I had needed to take it off and in several times before it worked (my SIM is old and I think I read that the newer ones, which you can directly cut into nano yourself, are thinner). I will try to order a new one.
Interestingly, when in the *#*#4636#*#* menu, I am able to see the contacts saved onto the SIM so the phone is clearly able to detect and read it!
