[Galaxy Note 4 Q&A, Help & Troubleshooting] Kookinen:
OK, *FIRST TIME POSTER HERE* so please excuse any unintentional ignorance of rules or etiquette.

I'm just super excited to get this phone working the way I like it, and it's all thanks to xda so I was moved to create an account to express my thanks AND hopefully help a few people back.

How? Well after reading through pretty much everything I could find on the N910S here and elsewhere, it seems that no-one (yet?) has been able to confirm a working mod that meets the following:

1. N910S Exynos Korean version

2. Some kind of custom English only ROM that removes the Korean characters from keypad and other network-apps

3. Removed bloatware

4. Easy-to-follow, how-to guide

Seems there were quite a few ppl who wanted the same thing so I just want to let you know what I did to get it working.

*PLEASE NOTE* Everything contained in this summary was found through over a week of tedious reading, research, trial & error. BUT in the end all the necessary information was contained, or linked to, in xda forums. It's just that all the relevant information and files were scattered over many different threads and topics. I'm just collating it all here to hopefully make it easier for the next person to find.

Background info: I'm technically competent but relatively new to phone modding - I've only rooted my HTC E8 before this to remove bloatware. This is my second project. I live in HK and started with a completely stock OEM Note4 N910SKSU2DPK2 after a factory reset. I then did the steps below in order (not including many failed attempts and re-starts, of course) These are just the broadstrokes of what I did, if you need to know how to do each step in detail then please search the forum. It's quite clear and there's no need for me to repeat it here anyway

As it's my first post and I'm in a rush to leave the house soon, I have not bothered with screenshots or links - I'm happy to provide if someone can tell me if the preferred method is link to the thread where the info was found, or you just want a link to the files I used. Again, they were all found through links in threads on xda anyway but I'll have to spend some time to find them again as I didn't bookmark them. Also, if you want the files someone will have to tell me how to upload them here. The filenames/packages are given in [brackets] so maybe you can just search for them?

0. Reminder to backup your phone and data first!

1. Root - was really easy using CF AutoRoot [CF-Auto-Root-trelteskt-trelteskt-smn910s] Just download to your PC and package includes Odin, which for first-timers is the official Samsung software used to flash to your phone.

2. Download:

- ClockWorkMod [n910s-cwm-recovery-6.0.5.1(1113).tar]

- SuperSU [SuperSU-v2.79-201612051815.zip]

- C Mod ROM [C_ROM_N910s.v2HNY.zip] (the site is Korean-based but google translate of the page was enough for a non-Korean like myself)

- N910S DPK2 modem file [N910S-20170114T050808Z.zip] The original thread had links to every modem variant they knew of, so should work with other S/L/K variants BUT of course I haven't tried them.

3. Copy files for SuperSU, CMod ROM, and DPK2 modem onto an external SD card and insert into your phone.

4. Put your phone into Download Mode (from power-off state, hold Vol Down + Home + Power)

5. Run Odin on your PC, connect phone. On Odin, click <AP> and select CWM file. Do not check or modify any other options. Click <Start> to flash CWM recovery to your phone.

6. Once it's done, disconnect from PC, and restart your phone into the new custom recovery mode (from power-off state, hold Vol Up + Home + Power)

7. Choose Install from zip and select the SuperSU file from your ext SD card. (I think this step may not be strictly necessary as it's part of CF AutoRoot, but SuperSU is always handy to have anyway)

8. Reboot into Recovery mode again (available in Advanced menu)

9. Install zip - now choose the CMod ROM file. Reboot into system and have a look around the new UI. It was at this stage that I noticed two things: my HK carrier SIM was not recognised, and as the ROM boasts some Note 5 features the Always On Display function would cause my Note 4 to not be able to wake up once the screen was turned off (manually or via time-out). I had to pull out the battery, restart phone, go straight into Settings -> Display and turn off the Always On Display functionality.

10. To fix the SIM card not recognised, reboot into Recovery Mode again and Install zip - choose the DPK2 modem file (or whichever version your phone's modem is). Restart phone, wait a few minutes and SIM should now work.

*ONE REMAINING ISSUE* Even tho my SIM is 4G/LTE, it seems to be connecting at HSUPA only. Could be reception, I'll check later. But I believe there's a way to select different LTE bands through secret codes or menu, not sure but I'll try that as well later and update if it works.

That's it - hope it helps! Thanks for reading, and don't forget I'm new to this AND a first time poster so be kind in comments/questions please :)
