We make new SW releases not just for fun.
Latest one is v1.27.
Now you need read NVM with latest version from alive sample and write to this one, repair security and unlock again.

Any good news JayDi?

Pufi164 · 07-06-2018, 11:01

Same problem but no NV backup:-(

Solution:

Download 339300B0207GEN_HR_BL7_V1.0.zip (easy firm)
CM2SPD as SC773X (android 6x) tick update nvm + repartition, and full flash.

Phone dual and other imei, but network ok, work and unlocked:-)

I did not experiment with it, I'm glad it works.
