try unbrick and fix IMEI HCU and IDT softwares


My histore is.

updated with RuHupdater v4 my mate9 for the ROM GPU turbo B377.

after trying to update again my mate9 did not start more, did not enter fastboot, did not enter the recovery, nothing, nothing.

the only solution was to testpoint and install the board software by IDT.

but the IDT has deleted my IMEi and partitions from the modem. IMEI is 000000000000

I was able to install the rom of factory of plate MHA-L29000000073

finally the HCU corrected my IMEI using this board ROM. But other functions were not corrected and the phone did not start after fix IMEI

so I had to install the Chinese STF ROM and leave it in the CHINA region for all functions to be fixed.

Ok, IMEI and everything working.

but .... this STF china firmware does not accept TWRP installation so I no can update my mate9 and get out of this board rom.

so what method should I use to have my mate9 updated and imei working at the same time?

thanks for
