Can I install CWM on the GS4?

Hello, I've been out of the rooting scene for over a year now since I bought my Galaxy S4. When I first bought it, i had it rooted but could not install a custom rom because it was on MF3. So, once again I am trying to get back into rooting with the latest OTA update and a NC1 baseband. I've been looking around on how to root and install a custom rom but I've been gone so long that I'm just lost.
From threads I have read I can downgrade my phone to NB1 then to MK2 to root. However, I haven't really been able to find an answer to if I can install a custom rom to it, only upgrading back to the OTA and keeping root. I have been having massive overheating problems with the stock firmware and have a large burn mark on the back of my phone and would like to switch back to CWM which i had on an old phone.

No CWM. You can only use Safestrap, a variant of TWRP for locked bootloaders that doesn't flash kernels. Due to that restriction (if we tried to flash a custom kernel we'd get bootloader check fails) we can only run ROMs which the stock kernel supports, meaning other Touchwiz ROMs and the one GPE that's been posted in the General section. Part of the downgrade and root process is using Safestrap to update to 4.4.2 with a modified OTA, and so you just replace that step with flashing a ROM, the kernel modules, and then the ODIN files.

[Q] G900R7 problem

I have a Samsung Galaxy S5 G900R7 rooted with towelroot. I want to flash twrp custom recovery but I'm not sure which way I should do this. I tried to use twrp's Google play app but it didn't have my phone's "codename". I had a rooted s4 with twrp and cm so I'm not a complete newbie. I just need a little help figuring out how I should do this.
Please help.
So far, only Dev. Edition S5 with an unlocked bootloader can flash a custom recovery like TWRP. More than likely you have yourself a retail version of the phone with a locked bootloader like the rest of us. The closest to a custom recovery we can get is Safestrap. I dont really know if the g900r7 is identical to the g900v so i would use caution of you want to try any of the methods here in this forum for root or to flash safestrap. A quick google search for your phone didnt provide much detail about it.

How To Flash A Custom Rom from Stock? {SGS 4 4g i19506}

Hello, I am new to this rooting and flashing stuff on the Samsung Galaxy s4 4G, and i just wanted to know how i can flash a 5.X.X custom rom from the stock 4.4.2 rom from the very beginning.
It would be nice if someone could post a link to a tutorial or something i can follow to flash my phone.
I have read some of the guides but i cannot understand what to do as the instructions seem to advanced.
Thank you
First you need a custom recovery. I recommend TWRP. Just google TWRP S4 and it will take you to the S4 section. There you have the download link and some install instructions. I recommend using the Odin method.
Then you need Odin. Odin 3.09 or 3.10 works. Sorry I cannot post links, I'm on mobile and it's pretty tricky getting everything together.
Flashing a custom recovery or rom is pretty much the same for all S4 models (with a few exceptions).
Installing the recovery is the most difficult part if you're a beginner. Installing the custom rom is as simple as selecting it and confirming the procedure.
Can i install TRWP recovery without rooting my phone?
Currently i have updated to the stock 5.0.1 rom and am trying to root my phone to install the custom recovery.
TWRP 2.8.6.0 is available as a tar file flashable through Odin without rooting. From there, upgrade to 2.8.7.0.
So is root required to flash a custom rom? Or can i just flash a TWRP recovery then flash the custom rom from there?
Thank you
Edit: Thank you for your help i have figured it out

Install Custom Recovery Samsung Galaxy AT&T S4 SGH-I337 Ver 5.0.1 Non-Rooted. OK2

Install Custom Recovery Samsung Galaxy AT&T S4 SGH-I337 Ver 5.0.1 Non-Rooted. OK2
Hello, I Want to do some modifications to my Samsung Galaxy S4 and Have so many questions that I am not sure were to start? Yes I'm a noob but learning. I have a SGH-I337 phone that is unlocked so I use it for T-mobile. The phone came with KitKat 4.4.2 NB1 firmware but I managed to update it manually to the latest firmware OK2.
What I would like to do is install a custom recovery and install a clean non bloated Rom. Maybe a custom such as CyanogenMod? Questions: Is there any recovery software that will work on my present upgraded phone such as Safestrap, TWARP,PhilZ or CWM and in doing so I am guessing I need to root my phone first? When you root a phone does that unlock the boot loader? I have read articles saying you can only install custom recovery on the older firmware such as kitkat 4.4.2. or unless a update comes out. I also have read articles that I cannot downgrade and am not sure what that means as I have read articles that I can use Odin and reinstall my stock firmware NB1 is that true? Is there a way to downgrade your upgrades?
I see a lot of articles how to install recovery software but they do not always say what firmware version they are installing it to so I wont even try it. I am guessing-it is the older firmware 4.4.2.
I have read I can flash my kernel to an older Kernel such as NB1 then root it install a custom recovery then upgrade the kernel again? Not sure it I can upgrade or downgrade kernels that are for my phone?
I did manage to root my phone awhile back when it had kitkat 4.4.2 NB1 but had problems later on with my touch screen going crazy as if someone was in my phone so I brought it back to stock by using Odin and reinstalling NB1 firmware hoping to fix the problem. After installing stock firmware I decided to upgrade to lollipop 5.0.1 OB2 and that is were I am now. About my touch screen going crazy I have been reading it may be due to cheap USB chargers which I am using but that is another story.
Well any-help or leads would be appreciated.
Maybe if I wait long enough someone will come up with a custom ROM for my latest firmware as well as rooting it?

You do not have a unlocked BL so you can't install TWRP.. There is a thread for rooting, just look.
Is there any one touch method of how to root the exynos 8890 version without flashing on the TWRP on just like king root does it
