Thanks, I realized that yesterday after i read through all 32 pages of this thread and realized it's not a necessary step, anymore at least, in fact it actually caused issues ( I believe) when going back to stock from a custom oreo. Lost my imei and baseband info, all showed as unknown, and literally had go to MetroPCS and get a new device because it was not even 30 days old and they don't know enough at my local corporate store to recognize a warranty voiding unlocked bootloader. Lol. Volte, 4g, texting and calls did not work so they warranted it out....
Has anyone had a similiar issue and FIXED the device?
