Just as the title says, the phone was working fine then suddenly it lost all signal and went into some kind of restricted mode, it's a friend's phone and he is almost 84 years old.
I have flashed the latest firmware and factory reset to no avail, also changed sim cards and here comes the weird behavior:
I don't have a standard-sized sim card so I had to take it from my USB LTE Modem, it's from another carrier and the phone detected the sim card, went with a full -77db HSDPA signal but data doesn't work at all, it seems to be disabled on status, even configuring the proper APNs it refuses to work. Can't test voice and all my other working sim cards are nano.
Inserting any other sim from another carrier results in no signal/restricted access but the phone still downloads the Internet/MMS configuration.
Have tried setting it manually to WCDMA and GSM, nothing seems to work, only my data sim worked so far *without the data*.
