I opened adb shell recently to find out garbled text. I tried using QPST as shown in [GUIDE][FIX] NULL IMEI or No SIM in Lettuce (YU Yuphoria) for solving my IMEI problem. I couldn't restore the qcn as it fails with the error "Received an invalid command from the phone" with the status "Memory Restore Failed". It also warned me that the phone model doesn't match with that of the qcn. I was wondering if this garbled text is the problem. Or is this normal for a IMEI nulled device?
