I bought this device for my girlfriend as a gift. It was curious, I began to dig in it, I tried the code to enter the engineering menu * # * # 4636 # * # * - it worked. There by negligence put usa band - in the end, one of the SIM slots does not work. I rummaged through the Internet and realized that the problem itself made a specific one. The model is new, there are no firmware anywhere as well as instructions. Can anyone help?
Almost 3 weeks since I restored the phone and gave the owner. Share experiences on restoration (if someone wants to repeat - at your own risk):
1. Install TWRP from 1 coolpad

For firmware file prog_emmc_firehose_8976_ddr.mbn need of drain firmware (replaces the file prog_emmc_firehose_652.mbn of TWRP file), I received from prodovat and posted here
