Hello. I have a Samsung S6 (G920a) that has an unknown baseband, with no IMEI or Serial showing under Settings. It is currently on the OJ7 firmware and shows up under Samsung Tool as being rooted (the Knox has not been tripped). I have 5 cert files for the G920a that I was fortunate enough to have sent to me by an associate. Although I used to flash phones using CDMA Tool and QPST many years ago, I am not knowledgeable on the steps needed to restore the baseband, IMEI and serial. I need someone to remote repair my S6 (I do not have paid GCPRO Key). Although I have very little financial resources available, I would be willing to pay someone who helps me out. Thank you, Derek
