Instructions
Make sure that your SM-G850W has the Lollipop bootloader and modem (The last installed stock ROM must be 5.0.2).
Flash TWRP recovery via Odin.
Boot to TWRP recovery (Vol UP + Home + Power).
Optional: Do nandroid backup
Wipe data / Factory Reset
Install the ROM (CM zip).
Install the Google Apps.
After you wipe the data
how exactly do you install the ROM (CM zip))
Do i do it via Odin?
Just need clarification on that step...
After you install twrp, you can make backups and also install software.
As suggested you better make a backup in TWRP it's called a nandroid backup. After that you have to do a factory reset, thats the wipe in TWRP. Then you can go to the install button, and choose the rom.zip. For Cyanogenmod you also need to install Gapps, because its not included in ROM.
But to be clear: everything is in TWRP.

Is this possible? Basically What I did was in this order
1. Install XXKH3 via Odin
2. Flashed [CF-Root v4.1] KH3 - su+bb+CWM4 via Odin
3. Flashed XXKH3 Stock Kernel via Odin
4. Flashed [CF-Root v4.1] KH3 - su+bb+CWM4 via CWM
5. Wiped Cache/Factory Restore via CWM
6. Imediately after Step 5 Backed Up via CWM
Will It now be possible to revert to KH3 Base via CWM from any rom that has CWM?
I probably missed a step by forgetting to wipe battery stats and Dalvik before Backup, would it make any difference?
Why do you even bother doing that?
You can easily download a stock rom from samsung kies.
http://fus.nanzen.se/
Download either the Windows GUI or command line (non-gui) version of fus downloader. Then download the ROM that you want. It is the same as the one downloaded using KIES directly.
You can restore any backup providing you have the backup on the phone and the rom has CWM .
In this case you restore what you backed up .
Personal preference to wipe cache dalvik cache then Factory reset before a restore just to clear any rubbish .

When you flash one of the rooted kernels, they also install CWM app which is in the system partition. Which is part of the rom.
Backing up the phone when part of the rom is still modified can't be called stock.
Clockwork recovery also backs up the cache and userdata partition. Really depends on how picky you are.
Just restore your stock rom backup thru cwm and it goes stock one assuming you have a backup..
Hi,
Currently using latest firmware KI3 with root.
I'm able to use CWM, backup, install zips, everything.
However, if i install a ROM trough a ZIP, i get a boot loop.
Only way to get back the phone, it's to install via ODIN with latest KI3.
Even tried with Litening Rom, and got the boot loop.
Any ideas ?
I was very keen to return to CM7.
Tx in advance.
Did you exactly what's mentioned here?
Install via ClockworkMod (do not use ROMManager for initial install):
Make sure you're running a rooted device.
Root your device and install ClockworkMod Recovery (http://forum.xda-developers.com/show....php?t=1118693)
Do a Nandroid backup!
WIPE (wipe data/factory reset + wipe cache partition) - do it for real.
Install the ROM from internal sdcard using ClockworkMod Recovery.
Do not reboot! We mean it - do nothing except choose zip and continue next step (if you come back to us with permission issues in install, we will know you did not read the directions and will call you an idiot). If it just plain hangs, reboot directly back into ClockworkMod recovery and continue at the next step.
Install the ROM from internal sdcard using ClockworkMod Recovery, again (due to a bug in the install).
Reboot
Install the Google Addon through ROMManager which is easiest, but you can
download the gapps.zip and install via ClockworkMod recovery instead.

Did you try flashing a old stock ROM like KH3, root it then try from this base?
I went from Villain ROM 2.3.5 to CyanogenMOD without any problems.
It's essential that you flash CyanogenMOD !TWICE! in a row when you're coming from a stock ROM.
Thanks.
Gonna check, as soon as i'm @ 127.0.0.1
Same behaviour, back to boot loop.
Tanx anyway!
I had a similar problem so here goes my help.
Cf root kernel uses a modified version of CWM that isn't compatible with CM7 or something like that. So what I did was flash this kernel http://forum.xda-developers.com/showthread.php?t=1118693. Get the kernel with CWM 5.x.y.z With that I got a compatible version of CWM and from there I flashed CM7. It is important that you do a full wipe, wipe cache, wipe dalvik cache, format \system, everything so you don't get any trouble. THen you flash the CM7 zip file, when tha t is done, flash the zip again for a second time (don't reboot just do it after the first flash). After that reboot. That worked for me at least.
A tip: If you can't reboot your phone and you have no ROM zip file to flash via CWM you can mount usb storage from CWM for putting the ROM in sd card and flash with CWM. That way you don't have to use ODIN to recover.
Tanx Tomas.
Tried with CWM 5.x.y.z and upon "WIPE" always got an error for mounting partitions.
Could't mount CACHE, SDCARD .....
Tx anyway.
Back to ODIN, back to stock 2.3.5
PS : I have to get a JIG to reset ...
Hi. I tried rooting my phone a few months ago, and installed TWRP and ashwin007's CyanogenMod. The rooting seems to have failed (I think I accidentally wiped something when I installed TWRP/CyanogenMod/GApps, causing me to lose the root or something. I'm not exactly sure what went wrong), but I managed to install TWRP v2.8.7.0 and CyanogenMod (on the 10th August nightly) successfully. Now I want to try rooting my phone again properly (with superuser access), and change my CROM to probably http://forum.xda-developers.com/one...m-kernel-unofficial-cyanogenmod-13-0-t3375221 (This also includes a newer version of TWRP right?)(I also want GApps!). I'm not sure which order I should do these tasks.
Should I just follow the instructions in the link?:
Installation instructions (for first-time installation):
First, perform a backup of your existing setup, and then perform a clean install (wipe /data and /system; TWRP is recommended).
If you plan on using encryption with this ROM, then flash the custom TWRP build in the Downloads section below before flashing the ROM. This custom TWRP build is needed if you want to be able to access data encrypted using this ROM while booted into recovery. Otherwise, you will not be able to access your encrypted data while your phone is in recovery mode.
Then, flash the ROM, flash a Google apps package, SuperSU if you want root access (ONLY v2.65 OR HIGHER), and then reboot.

A few things I want to clarify:
1. The SuperSU installation page says it requires a rooted device. As stated earlier, I'm not 100% sure whether my device is rooted or not. What should I do? Root my device (What's the best way also, KingoRoot or something else?), then follow quoted instructions?
2. For the clean install I just wipe /data and /system? Not System, Data, Cache & Dalvik?
3. After I finish wiping and installing all of those, is there any way I can restore all of my apps and associated data that I had? (I've heard something about using TitaniumBackup?)
From what I've read, I probably should:
Use my TWRP to backup all the other things (system and stuff)->
Root phone (using KingoRoot?) ->
Download and use Titanium Backup to backup Apps ->
Wipe /data and /system (or System, Data, Cache & Dalvik?)->
Flash new custom TWRP (Can I flash it using my old TWRP? The TWRP official website says you can do this with TWRP versions v2.8.4 and above, mine is v2.8.7, but that was for the official TWRP)[or should I use the android SDK tools bootloader thing?] ->
Flash new custom ROM with TWRP ->
Flash GApps with TWRP ->
Flash SuperSU with TWRP ->
Reboot phone->
Restore apps with Titanium Backup
Could someone confirm? I don't want to brick my phone Thanks a lot!
Just follow the guides for rooting and custom Recovery's. If you follow the steps you won't have any problems. First thing you must do is update your twrp. Assuming you have already unlocked your bootloader.
Hi All. We have Stock ROM zips for TWRP as you know. But i have boot problem if I install them with instructions which on topics. I know i am not alone who facing with this problem. This Guide is competible with all models.
Here are the steps to install Stock ROM from TWRP.
1. Check first;
Once you booted to TWRP , Tap Mount and Check "Mount, System as Read-only", this is very important
2. Install bootstack and system files.
3. Wipe Art & Cache.
4. Reboot Recovery. (Not system, just recovery)
5. Install SuperSU now.
6. Reboot.
SuperSU will not be fully installed if you don't reboot recovery. So you can not boot.
..
To perform a completely clean installation of a custom ROM, boot into TWRP and wipe system, cache, data.
I have always flashed performed a complete wipe, flash the ROM, flash the kernel, and reboot the phone and set it up to make sure everything works. I then flash gapps.
..
If you want a completely reset device then you need to flash the stock firmware via odin twice with a factory reset via the stock recovery in between flashes. This doesn't reset the flash counter, just everything else.
If you want to reflash a custom rom after that then you root via chainfire, install twrp and flash Los via twrp.
If you want to flash a kernel or anything else you can flash via twrp whenever you want but make sure they are compatible.
If you want to use magisk then you will need to refer to the installation instructions for both magisk and los. It will most likely involve uninstalling supersu and its binaries.
If you have issues with cell signal then you can look at flashing other modems. If no problems leave it alone.
