After using eu rom (maybe earlier not sure) i couldn't get fingerprint worked. Trying to reload persist.img from twrp tried to fresh install eu rom but didn't work so far. When i saw an article that says "go to advanced settings. in CIT menu ,in right corner you have three dots, go to advanced manu, find fingerprint settings, find black ,and find white paper for test, when you finish this " it gives error on first white test as 1525 calculate PGA gain error on CALC_GAIN_TWO_LIGHT_MEAN test so i couldn't get to second test (black paper one) Any ideas? Thank you. I have mi 10 and latest beta rom right now.
