I think that oppo have signed imei with the PCB.
So you can do repair only original imei instead of change.

iTMed · 08-05-2021, 02:19

When I enter to engeneer mode with *#888# the PCB number is empty ,so what is the solution

Wolf Tech · 08-05-2021, 05:29

just flash nvram.bin from rom readed with cm2 don't flash nvram readed from emmc tool. when u read firmware cm2 also read nvram.bin.read this from another phone. first unlock bootloader and then flash nvram.bin otherwise it will fail to write nvram.bin, or if u don't have another phone just read firmware of your phone and before flashing initiate emmc tool and erase nvram, nvdata, nvconfig,persist. open scatter file search for nvram.bin and make download false to true. now flash with cm2 all files and check imei will be restored. i have done this with oppo a1k it's working only for original imei.
