so i downloaded ww 1906.24 after that i updated to ww 1908.12 and i don't like it so i came back to CN firmware on same thread and i flashed CN 1906.24 it is run and i get the last update via OTA 1908.21 but now i am stuck i can't download google play and if i downloaded by getting old version it work but when i restart my device it break and it force me to make factory reset so now i want to return it to full CN Rom it still have some file of WW as i see . thanks
here's the latest 1908.21, unzip, remove original zip from folder (if it's exctracted to same place) and run flashall_AFT.cmd, wait for around 10 mins with cmd open, the device will restart maybe twice, then it's done...
