G8X修复指纹炸掉教程

1. Assuming u guys are on android 10 unlocked bl. Downgrade to 10c using lg up.
2. Go to service menu, svc menu, handprint on.
3. Then imediately go to back to device test, saat, manual test, optical finger test, do the test. Press hard on fp till text turns green. Will say test failed. Still click yes.
4. Go to setting and fp starts working.
Thats it no restarts no nothing. You have fp in these few steps.
This is for LG G8x Indian Flipkart Big billion sale model.
To go into Service menu. open dialer and key *#546368#*850#

1. 解锁，刷回安卓9
2. 拨号界面*#546368#*850# 进入工程模式→svc menu→handprint 点击为on
3. 马上返回到一级菜单device test→saat → manual test →optical finger test→进行调试，每一步都做完，手指摁着传感器蠕动，会提示失败，无视，做完就能回去设置指纹了
然后可以选择刷回安卓10，指纹还在
