I had a problem with the buttons when a change the rom from Galaxy S5 G900
because g900 there is no preseed back button and menu button
home button only works because both models have pressed
after several hours of different combinations I came to solve the problem
Install ROM complies with the letter of your phone model
if you have g870F is a need to install rom with g900F not 900A or another model, otherwise you can lose your IMEI and network signal
First your must FULL backup your ORYGINAL S5 ACTIVE rom via TWRP or CW
Then do wipe before installing rom Galaxy S5 G900 (not active)
Install zip your new custom rom g900
after installation, do not reboot your phone !!!!
in TWRP, select the Restore menu
Select partition to restore
select ONLY BOOT
Then swipe restore
and reboot the system
now preseed back button and menu button should work
only one bug key activity does not work because s5 g900 does not have such a key
Hit "thanks" if you find it helpful.
