Soft Download

Hello Support

I have a brand new phone on which I tried to repair IMEI (because old one was blcklisted) Have tried to repair IMEI but according to the procedure when phone restarts after switching to download mode its actually all hard reset so the bootloader again locked and root permission is also removed, now phone is like in factory state as before thus process just does not completely finish and gives error.

Log is below to understand the situation, please adv how to solve this problem.

Thanks for the usual help!

PS**I have saved backup of QCN and NVM which also I tried to restore to even bring the old IMEI back but still no success!
