i found the Frimware 2018092612_c223v37n_dfl_pro.zip under https://drive.google.com/drive/folders/1U8QI3bhf8sF43fAYTWkbGDe4P9KuLsw3 and flashed the firmware with "SP_MDT_exe_v3.1812.00.00-A2018.08.30-v1.5-unihertz" on my Jelly Pro. After an error i recognized there where a wrong Firmware on your download portal.
If im going to verify now i can find the right Firmaware 2018092612_c223v37m_dfl_pro.zip (diff 37n and 37m!!). But now my Jelly Pro wont be recognized anymore from "SP_MDT_exe_v3.1812.00.00-A2018.08.30-v1.5-unihertz" and the phone is dead!? What should i do?
Hi, for all facing similar problems. I solved this. There are out different Versions of the flashing tool from Unihertz. I used version 1.5.1 and version 2, both not recognizing my Jelly Pro anymore. Someone on XDA gave mi the version called 1.5.1 in the zip but spitting out the version 1.5! With that version and setting parameter for not recognized phone like in documentation of Unihertz i was able to bring back to live my Jelly Pro. So never give up trying!!!
