Isn't there a link and guide to a deoxed slim downed TW ROM on the page before? Might be worth a try.
Looks good...however feel I may be still stuck with my 'not able to install from SD card' issue. Is this a locked bootloader or something else?
Just tried to get into recovery mode using vol up+home+power and ended up with a 'Downloading - Do not turn off target' that you normally get with the vol down+home+power. Text at top says -
Could not do Normal boot
ODIN mode (High Speed)
Product Name: SM-N910F
Current Binary: Custom
System Status: Custom
Reactivation Lock: Off
KNOX warranty void: 0x1(4)
Qualcomm Secureboot: Enable (CSB)
RP SWREV: S1, T1, R1, A1, P1
Secure Download: Enable
UDC start....
Have I managed to do something wrong when flashing the recovery?
Is it best to do what I was planning and go back to stcok ROM and start the whole root, unlock and install of recovery again?
