[Q] How to install CWM or TWRP?

I have tried many methods to bypass boot loader and install CWM or TWRP on i337 phones, all for which they failed, I am not sure whether because I have NC1 device
My phone is Rooted, NC1, My ultimate objective is to install T mobile Rom, so I can get Wifi-calling on my at&t, what do I need to do in order to that??? I am willing to downgrade or anything to reach my objective.
Here are some guides that I saw at
galaxys4root dot com
"How to Install GT-i9505/T-Mobile Custom ROMs on AT&T Galaxy S4!"
But i couldn't Install cwm or TWRP to proceed. Please Help.

you are post mdl build and can not run cwm or custom twrp only safestrap recovery. surprised you didn't run across that when you rooted and installed safestrap--
as far as wifi calling--don't know, but believe i have read not on an att phone

OH right (I did this long time ago so forgot most of it), So if I wanted to install a tmobile s4 custom rom (DARTHSTALKER) on my i337 I could use safestrap, and then flash my kernel using odin for it to work? or that would break the phone?

not sure, i don't use SafeStrap and not familiar with rom
i would make sure it is safestrap compatible and see if any other att folks have flashed it
i do that by skimming last 30 pages and in-forum search for safestrap and att
or you can ask, but have found most times you get no answer on those type of questions. it has to be TW based--

You can get full root access on NC1

It's very hard to achieve what I did in these screen shots... sorta lol I just got the phone delivered yesterday at 2pm and hit Red Bull for 15 hours hacking it... I have full root access in system... knox is frozen by TiBu as you can see SELiniux is permissive, SuperSU Pro in control without a popup warning... I do have a new boot screen though with the unlocked lock lol. Bye bye warranty! I bought the 2 year replacement one and they don't care if it's rooted lol.
Check out the screen captures... I had to slug it out getting one app at a time til I finally figured out how to get TiBu su access... that was the key! I'd have to write a small novel explaining it, and I'm tired as heck lol. Some shots were too big. Point is... its stable I don't think you get this with safe strap do ya? Maybe ya do... but I hacked it lol. Still stock OS with a lot of freezes. If this is something different and ya wanna know reply to the message, but it takes a while and you need to really know your adb commands and be good with terminal emulator because it' s literally all you'll have for most of the 'fight' with Knox... and it really is. Lucky it didn't boot loop lol but I wanted full root access. I'll just deodex it and get rid of the bloatware later. I still wish I could flash CWM though lol. I like AOSP roms

Would have been easier on you to use TowelRoot which would give full root access and then use safestrap for its recovery. Could of avoided the 15 hours in about 1 minute with the TowelRoot app

I did try it. Several times. Didn't work at all... It was a lot of fun doing this honestly I haven't had a good challenge in a while lol. I managed to hack knox out of my device using nothing but the device itself and knowledge I have. I really don't want multiple Roms in my device. I just want one ROM like I have in all the others, and that's what I have now and I got CWM installed last night finally... A bit glitchy and not 100% stable yet... It has issues backing up to external SD for some reason. It'll backup to internal though. I used it to flash a small and meaningless update.zip I assembled to test it and it worked with it I'm not sure it would be successful using a backup yet either to restore the device... If I just used towel root I wouldn't have ever figured any of this out, and if I can get it a bit more simplified and figure out which particular steps or combinationof steps allowed me to exploit the system and get it in tthere and I can get it stable... I can tell everyone else how to do it. A friend on XDA is working on a tool now to simple install SuperSU into system... He done it on another device and got cwm installed on a device with a locked boot loader also. I used some of the code to get an idea how to do it on the sgh-i337. Its not impossible... Just hard to figure out I think that's one of the things XDA exist for... To learn and progress and help others... Right?

Well Great Job then, I do applaud you for your work you done. Hopefully for those that are stuck using safestrap you can get it to the point they could use cwm. That would be awesome.

I seriously would not try that using safe strap in i337 @ this point. The ROM would need to be ported as a multicarrier , which is pretty simple in and of itself... A lot of debugging I'd imagine though. You'll only get 2g speed using ATT device on TMO ya know. They have different 3g and 4g LTE bands. It just won't work. If you flash that ROM.. IIt's very likely you'll soft brick or hard brick the device. I have the ATT kernel decomped now working with it... I haven't downloaded any existing ROMS used with i337 yet, but I'll get one and check it out and see what has been done with Knox in it. Just very risky flashing a ROM not specific to your device...

(when I did this on my driod maxx it locked the bootloaded and I was no longer able to root or use wifi so I got rid if it. )
-should/can I install this leaked lollypop am seeming.

Do NOT take OTA update for the very reason you have described. OTA will put you on 4.4.4 which their is no released root for yet. All other ROMS right now are based on the 4.4.2 version that was previously on our devices.
You can NOT installed leaked Lolipop ROM as that is not for our device. We will have to wait for our carriers version or possibly a port.
Once you get your device you should be able to root using Towelroot which is just a simple .apk that you sideload and run. https://towelroot.com/
Then go to this thread and install Safestrap which is the Recovery we use for our device since our bootloader is locked. http://forum.xda-developers.com/showthread.php?t=2517610
Follow those instructions and then you should be able to go into the Development section and load up a custom ROM. I also HIGHLY advise you take some time and read thru some threads before diving into this to educate yourself before you break something.

-No that ROM you linked to in the video is NOT for our device. That was for the international version. I believe Poland or something like that.
-Do not know about the Note 4. Would take that question to that forum. But OTA update on regular Note 3 for Verizon WILL remove root and bootloader was never unlocked.

Root and you can disable this or use a custom rom.
Rooted method:
Download "disable service" from Play Store
Open it
Go to System Apps
Find Google Services Framework and tap it
Uncheck "SystemUpdateService"
Restart your device.

Thank you very much all worked perfectly, I had an issue when installing superuser removing knox seemed to hang, but I restarted the phone and all was well. on my old Motorola rooted phone I used Android-wifi for free wifi, is this also recommended for my new note 3 or do you recommend another option.

Hey I disabled the service but its been 12hr later and that update window has come up again, I looked and is show that the box is unchecked...

If i were you I'd look at a dev note 3 developers edition that way no locked boot loader and you can rom way more than on regular note 3 if someone posted this my apologies I did not read everyone's post. Thanks

Very NOOBy, but I would like some things cleared up.

I currently have an S5 G900A on 5.0.
Am I able to root this phone as is?
If not, am I able to root it by downgrading it to say 4.4.2?
How would I got about doing either of these?
I'm sorry that I'm a big noob at this, but I would like to root my phone and I'm having issues right now.

With an AT&T branded device, you will find things difficult at best......
You have zero chance of downgrading successfully due to a locked bootloader and security measures put in place by AT&T........
Some XDA members have given favourable mention to a process called (I think) safe strap, but as I have never had to use it, I haven't needed to research it.
One thing is for certain though.....
While you *might* be able to attain root, you won't be able to flash a custom recovery to your device.......blame AT&T and their almost apple like desire to retain control over your device........

Help a total noob here! I just got my first ever android device and I'd like to get rid of the pre-installed bloatware from my carrier (rogers canada). So I started researching how to do this and discovered this whole rooting business. I couldn't find much info on the specific model I have though. I installed kingroot 4.9.0 on my phone and got to "try too root" button but not sure if I should try it since I have no idea what to do if something goes wrong.

Nothing will happen, it'll either root or not root, chances are it will root your device and can freely remove Samsung/carrier bloat. Just don't remove too much that you not sure on.

Ok, I'm gonna try it but do you think I should back up my apps to an external drive and get the stock firmware first just in case? If I reflash the stock firmware on the phone, after rooting it, will that unroot the phone? I'd like to be able to unroot it and go back to stock If I ever need to.

"New" comer here, I need some help please

Hey guys, I have been out of the android world for a couple of years, I would appreciate some guidance.
I I'm currently living in US
T-mobil
Model number: SM-G935T
Android version: 6.0.1
Updated right now
So my question is, since I don't have any backup or anything, can someone provide me with the steps to get me started? Like what post to root it on this specific carrier and how everything? please
Thanks

Of course we can get your started but see
But first you must answer us these question three.
Why do you want root?
Do you have a computer? (This is a must for root.)
Are you ready to be disappointed?

https://forum.xda-developers.com/tmobile-s7-edge/how-to/how-to-root-s7-edge-t3410470
follow this (use odin to flash rooted kernel) ......you should search before posting things like this.....google is your friend bro.
GOOD LUCK - BTW use flash fire app in play store to make backups and flash roms

Okay okay.
A quick glance at T-Mobile Samsung Galaxy S7 Edge Guides, News, & Discussion would have led you to the "How to root the S7 EDGE" thread.
I'd take a look in there if I were you.

Well while I was waiting I just rooted it. So what do you think that would be the next step towards installing a rom? To answer your survey questions :laugh: :
1- Because a phone without being rooted is like a bird without wins.

Well then.
Rooting the phone (as I'm sure you had already found out) was fairly easy.
BUT... since we do not have an unlocked bootloader then we cannot have any custom recovery. Which means we can only (for now) use adb and Fireflash to flash any custom firmwares. And while we're on the subject of that... there is only one custom rom. Well... technically there are two but only one for you since you updated to the latest firmware.
Echoe ROM which was updated (ummm...) September 9th (not including the Verizon version which might work but with no promises)
Tekxv2 which was updated back in July. Unfortunately, that is flashed by adb (computer required) and only supports G935TUVS3APD8 which is... pretty old.
Things that you may notice with root.
Battery life may be shorter.
Strange icons on your status bar.
Might start to have random reboots for absolutely no reason.
Can't use Samsung Pay and some other apps.
Phone might be laggy.
Phone might feel hot.
Some of those can be resolved by flashing the only custom rom that we have (Echoe ROM... which is a rather nice rom) but it's not "there" yet.
Or you can use the guide in my signature to resolve issues like the lag and the strange icons. Yet even after the "fix" you might still experience both again from time to time.
You might even have the IMS force close issue which I used to get about once a month. It would piss me off because no sooner that you click the button, it'll pop up again and you don't have time to do anything. You're pretty much forced to reflash stock, wipe, re-root, restore a latest backup... which can take hours and is rather inconvenient if it happens to you while you're at work like it always seemed to happen for me.
SO...
All in all... root is okay. It's better than nothing I suppose. But until we get more developer support for this phone then in my opinion it's kinda pointless in my opinion.
Too many drawbacks. I eventually unrooted two weeks ago and I love my phone now. I'm using the heck out of Samsung Pay especially since their promotions are pretty nice right now! Plus a few members are testing the Nouget update which probably won't be getting root at all since rooting requires an engineering kernel which we don't have and might not get. Or an unlocked bootloader which we've pretty much given up on.
A lot of members that are testing the Nouget beta firmware are extremely satisfied with it so if we can't root Nouget then having a rooted S7 will probably fade away as more people update to Android 7+. That's where I see this going anyway.

So for what I understood the dev support for this phone is very limited... I know the issues I may encounter, I had them with the galaxy note. but any way... If something I'll unroot it but I want to try it out Thank for you time. I've rooted it.
EDIT: Damn... I really don't like the visual style of Echoe... is that one the only one I can flash??

How are you doing with the ads? Like youtube, pandora, spotify? I just installed xposed and the phone feels very hot, and If I unroot it (which I'm thinking to do) I won't be able to get things without ads (I know about vpns and browsers). Also how can I install teaks for apps? Installing apks from pages that promise you this and you have to log in is very untruthful. Any suggestions to all this?

I just put up with them.
In all reality, I don't use my phone for the purposes that require my viewing of ads to begin with.
Sure when I was rooted I had adblocker. But honestly, I had completely forgotten all about that benefit of being rooted until now.
I suppose if you absolutely need to be rid of ads then by all means, retain root. However ads don't effect my daily use one bit.

You're probably trying to flash a firmware with a V3 bootloader over G935TTMB4APK1.
If you were seriously following that (outdated) guide step by step then you tried flashing TMB_G935TUVU3APG1.zip over a PK1 firmware. Yeah... that doesn't work.
Download the latest firmware from sammmobile.
https://www.sammobile.com/firmwares/database/SM-G935T/
Try it again.
IF that doesn't work... try using Smart Switch.
I haven't done it before but I think it's the Emergency Software Recovery and Initialization.

Odin this to return to stock firmware.

You have no idea the help you gave me. I went to sammobil before but since it said that the download speed was too slow, I didn't do it through that page. Now I did it and it's working fine thanks bro.
But when I start it, it says: custom in the log in, how can I totally put it original?

If I want to remove everything and just leave it plain how it comes from factory when you buy it, do I just flash the AP file?

You should flash everything.
BL= Bootloader (which should be V4 since you updated to the latest firmware already. Anything less than V4 will fail.)
AP= Is for System, Cache, kernel, etc.
CP= Is for modems
CSC is for your HOME_CSC_TMB_G935TTMB4APK1_CL9507190_QB11413830_REV02_user_low_ship_MULTI_CERT.tar.md5 file.
Important! If you use the CSC_TMB_G935TTMB4APK1_CL9507190_QB11413830_REV02_user_low_ship_MULTI_CERT.tar.md5 (doesn't have the word "HOME" in the name) then it'll wipe your phone!
If your phone still says "CUSTOM" on it then make sure that reboot and check again. If it still says custom then make sure that you don't still have the engineering kernel. Re-flash the AP files again if so. It shouldn't though if it's 100% stock. Also note if you saw the unlocked padlock on the S7 Edge splash screen (before the bootanimation).
Good luck and happy New Year.
