Using TWRP, I just installed new ROM (ResurrectionRemix-M-v5.7.4-20160922-libra) and OpenGApps (open_gapps-arm64-6.0-pico-20180830) on my Xiaomi Readmi 4c. Both of them were flashed successfully (or at least that's what the twrp said :D), there was no error or anything.
Then I went to "reboot system" and it returned back to the TWRP menu. I cannot boot into the newly flashed ROM.
Please help me solve this problem.
