FOR THOSE WITH LAG ISSUES:
You will still be rooted using this method!
(I posted this on the oreo rooting thread in a reply but making a thread so maybe more can see it!
I was well aware of the lag issues that came with using the eng kernel, but it got to the point even with all the tweaks & mods (L-speed, kernel auditor, etc.) I was still experiencing severe lag (mainly doing things like listening to music and using snapchat at the same time, phone became unusable with alot of hangs and freezes!)I was just about to flash back to stock oreo because I felt that the trade off of Root for lag wasn't balanced.
But then I remembered seeing a post in one of these threads...might've been during Nougat days or more recent oreo, I do not remember, either way, flashing the stock BL in odin would fix lag completely. I was willing to give it a shot mainly because I was going to go back to stock anyway if it didn't work and to my surprise the phone booted! After everything settled after boot, I already noticed the difference, it was substantial!
Now, if you have already fixed your lag issues by other means then you don't need to read this post! but for some that still have tried everything and you still experience extreme lag, these are the steps I took to fix mine:
1. Was rooted on @jrkruse [Rom][ALL_CARRIERS_CRG2][Stock_Oreo_Hybrid] ( the lastest one which is CRG2) -------> this is the only rom I can say this works on as I have only tried it on this rom
2. Assuming you are already running his rom and not stock oreo (if you are running stock oreo then I cannot say if this will work for you or not, I would suggest going to his rom)
3. In his OP in, [Rom][ALL_CARRIERS_CRG2][Stock_Oreo_Hybrid], download the odin files (SM-G935U_G935UUEU4CRG2.zip)
4. Extract it and find the file [BL_G935UUEU4CRG2]
5. reboot your phone into download mode and flash the stock BL
NOTE: By the time I did this I was already on @jrkruse CRG2 ROM and already rooted, so I suggest the same to avoid any unseen complication! Flash the rom using his instructions, root using his rooting guide and then try this
This worked for me great! I can say that the phone is running VERY close to stock speeds and I have not noticed a single stutter or framedrops, I even tried remaking the same situation that would cause the phone to freeze and the phone did perfectly after doing this!
Let me know if this has worked for anyone else!
Edit:
This is also fixed my heating issues as well, the phone does not get extremely hot anymore
Edit 2:
along with this fix, I have L-speed set to 'Performance' profile and governor set to interactive, no other tweaks
You will still be rooted using this method!
