Hello everyone I have the same phone g925t. It was brought in by a customer I noticed no signal and looks like efs was reset null imei and a serial number. Also was on epd1. I've been trying to fix imei with everything I been reading, downgrading modem downgrading f.w etc. I'm getting reading data error on z3x. I'm starting to think my z3x may be going bad. But the thing is I don't have any backups for it since they brought it in. Do I need efs? NV? I have a cert. Could it be they updated to epf1? Please help.I'm going on my 3Rd day. Thanks

I'm I've been trying out modems and nothing they all give baseband unknown I was reading something about modem bits that the number must after the last 3 letter is important. PF1 has 4PF1 and no modem before as of now is 4 we are looking for a way to write the imei anyone?
