running twrp 2.7.2
but had the prob since 2.7.0
the problem is when i try to restart from my rom to recovery sometimes like 50 % of the time i have one of 2 bugs either a
firmware upgrade error bla bla bla ..
or strange download mode screen with no info on the top left side (which doesn't work with odin ..i have tried )
restarting the phone from the first case always fix it and everything is back to normal
the second one is tricky sometimes just a simple reboot fix it and sometimes i need to enter normal download mode and install the recovery again which then the phone boot's to it and from then to system
any ideas what's the cause of this ??
and had this problem over a variety of roms and twrp and philz recoveries but i mainly use twrp
