I have been troubleshooting what happened to my router for days.
I attempted to upgrade the modem firmware using the guide on glinet documents.
I flashed it with the EP06-A firmware and now my router doesn't get any cellular sim connection.
I read quectel forums as well and saw someone with a similar problem was able to flash a firmware EC25AFFAR07A14M4G_01.003.01.003 to resolve issues.
Is there anyway I can get help with the correct modem firmware to flash to my x750v2C4?
If the model is EC25-AF, you can use this firmware package update.
EP25-AF: Unique Download Link | WeTransfer
EP06: please get the firmware from GL DOCS.
