C. Recovery Problems
Most recovery issues can be solved by attending to the following issues.
1. Did you root using the full ap file patched Magisk .
(This contains the patched boot.img and vbmeta.img)
Exynos 850 users must use the special a217 magisk?
2. Did you then go all the way through the setup process?
3. Did you download the recovery to match your baseband?
See
https://t.me/a127f_res/54 for Exynos 850 recoveries
4. Did you hold down power and volume up after Odin says pass?
5. Did you format data from stock recovery?
If you forgot to do this, just install stock recovery.img from TWRP and reboot.
6. Did you type multidisabler twice?
7. Did you reboot to recovery by choosing reboot from the menu and then choosing recovery?
8. To avoid touch issues go to settings and untick "allow time out"
