I tried to root my S4 clone mt6575 phone 1 month back using the mtk droid tools. It backed up the stock rom with two folders in the backup. After rooting next day when I rebooted the phone there were no signals and after checking the settings, to my surprise the baseband was unknown and imei was not there too.
I had backed up the user data using the stock recovery option of backup the data, but its only restored through original recovery only. So reflashed the old recovery and restored the userdata everything came back but the setting shows the baseband unknown and imei blank. Still unable to call as radio is not there. Surfed a lot but till date am not able to find the solution.
This is for every senior member who is there in XDA. Can u pls help me out in this. Is there no way to restore the baseband? Because without the baseband, imei cant be written using any tool or for that matter using terminal emulator too.
Is there any method to convert the userdata backup done using stock recovery to the sp tools flashable images. I am ready to upload my backup if someone out there is ready to help.
