ive found one root option that seems to work but you cant install a custom recovery.
my phone came with the mk2 update from sprint so is there any way to root it and have a custom recovery? im not worried about tripping knox if that matters. also does the cf-auto root method work with the full mk2 update?

How did you root it? I dont know about custom recovery but I don't mind not having it.

I rooted my cousins mk2 s4 by just flashing philz recovery then I just flashed sacs rom..that was all I did..I dont know if it triggered knox ...theres also safe root which wont trigger knox I think

Isn't that the method that ends up installing a root kit on your computer and sends all your personal information to China.

This is what worked for me
You've probably already found a solution, but this is how I rooted the Sprint MK2 4.3
http://www.youtube.com/watch?v=uii_mYm8IGE
This worked fine, and I was able to install custom recovery. Just been having and issue getting a proper backup, but everything else worked just fine.
Hope this helps

The method is for Verizon GS4, can you reconfirm that its working for Spring L720 too?
Thanks

I can confirm that it worked for my Sprint MK2 4.3. I should mention that when I started the instal bat and the command prompt screen popped up telling me to hit any key to continue, nothing happened. I "x'd" out of command prompt and started the install bat again and it worked no problem. I have done this a total of 3 times now. All on Sprint MK2 4.3 and all successful. I checked each time with root checker to ensure root access.

I can also confirm that Safe Root tool was able to root my Sprint L720 MK2-based 4.3 Galaxy S4. I had Odin'ed back to stock MK2 days ago. I haven't tried the SafeTrap Recovery yet so I can back-up/install custom ROMs.

can anyone confirm that SafeRoot does not trip KNOX?

Thanks for the confirmation as it assured me enough to go ahead and root... and as confirmation on my end that it worked!!
One question though... as I'm now rooted, it's been mentioned that when you boot the device up you should see a "Custom" banner during boot because things have been changed. On my device I never see this and was wondering if that's the case on yours as well.

I can also confirm that QBKING&&s root method works for mk2 build..so does goomanager for installing twrp and disabling knox. Jut dont try the MJA native hotspot mod...i followed the video to the t and am now stuck in a boot loop

Why would you use the MJA native hotspot mod for a MK2 build? I believe in that same thread they released an MK2 hotspot mod as well, which I have installed successfully as I now have FoxFi WiFi hotspot availability!

So if I use goo manager to install twrp I won't trip knox? How can I install philz recovery and then sacs rom without tripping know?

Root GT-N7100<4.4.2> without tripping KNOX

Hi XDA people,
Just found this workaround for rooting latest 4.4.2 stock firmware without tripping Knox.
This method downgrades the firmware(System & Kernel) on your device to N7100XXUEMK4 except for the bootloader.
Dont even try to downgrade the bootloader as this isn't possible.
What you need:
1.Odin v3.09
2.Stock official N7100XXUFND3 firmware on your device.
3. A device with Knox Warranty Void: 0
Procedure:
1.Download N7100XXUEMK4 Stock Rom from HERE
2. Open the downloaded file.You will find 4 .tar.md5 files and an Odinv3.09 zip file inside.
3. Extract the Odin file and setup Odin on your PC.
4. Next extract the file named AP_N7100XXUEMK4_2099172_REV04_user_low_ship.tar.md5
5. Load this file into AP tab on Odin. Connect your phone in Odin mode and flash this file.
( Note : You have to flash only the AP file from Odin. Do not flash the other files namely CP, CSC, BL)
6. Now once the phone has rebooted go back to download mode and check if Knox has tripped or not.
7. Next use Saferoot from HERE to root your device.
(You would find the guide on how to root using saferoot easily over HERE
8. Now if saferoot was able to root your device then you must be rooted without tripping Knox. :good:
9. Now you can easily flash your official firmware through mobile odin. Select Everroot option on Mobile odin while flashing the new firmware. In this way you wont lose root access.
Known Issues:
If after rooting you want to flash custom recovery via mobile odin, or via DR.Ketan's utilities app please note that it will trip knox.
Knox remains cool until your recovery is stock. The moment a custom recovery is detected knox goes 1.

Cant you just do this?
Use Mj5 bootloader and any rom 4.x
Flash Kitkat 4.4.2 via mobilOdin and root.
Make sure status is ok (use triangle away if not)
Flash latest 4.4.2 bootloader via Odin (pcOdin)

Surely it can be done that way.
This is for those who already upgraded to the newer builds.

What i mean was use Triangle away before you flash the 4.4.2 bootloader to get official status and binary count 0, the knox in MJ5 always stand 0.

I don't think flashing ND3 BL will trigger knox.
Most of the users already flashed ND3 BL from MJ5 while they were on DN3. It doesn't trigger that way.
And yes about that guy, he never mentioned any detail that he downgraded from ND3 to which firmware of 4.3.

I did read them. They got knoxed means they got a BL with Knox warranty Void 0. And @paarkhi confirmed it to me
And I really don't think it would trigger knox that way because the bootloader doesn't check the integrity of the firmware on your device when you're flashing the bootloader itself.
Also it doesn't trigger Knox while it boots up the system and finds unauthorized firmware.
Because we don't have Kernel lock and secure boot like on Qualcomm based N3.

Okay this is all too much for my brain to absorb at this time of the night ,i don't think i actually understand the difference between Knox warranty void and being Knoxed ,i guess since we install de-knoxed ROMs we can't get Knoxed ,just that our warranty goes out the window and we cannot downgrade beyond a certain OS right? If what i stated is wrong then i'll go to bed and dream of knox

Lol. It's paritally right.
Don't worry buddy I'll help you learn Knox
Being Knoxed is getting that extra line in the download mode.
But this doesn't throw away your warranty. Warranty is lost only when this extra line in download mode ends with 1 instead of 0

No feedback yet. But one thing i can say for sure that even if this method fails it won't hard rick your phone because we ain't downgrading the BL here.
And I found a similar method on S4 active forums. It seems it works very well.

Yes it would trigger by flashing unofficial firmware.
But here we ain't doing that too.
We're just flashing a older kernel+system partition (the whole PDA from MK4) that was vulnerable to root without tripping knox.

I thought Bell had i337m. If you are on i337, the downgrade, root, and Safestrap doesn't trip Knox since Safestrap doesn't go in the recovery partition. That includes if you flash stock ROM with root or any custom ROM compatible, since Safestrap doesn't flash kernels.

ok a few more questions.
on link http://forum.xda-developers.com/showthread.php?t=2692825
the steps are:
1. Place the I337UCUFNB1_100%_Stock_Rooted_ROM in the root of your ext sdcard.
*2. Download the I337_NB1toMK2_Downgrade file(MD5:FAC95B4CC7743FAE34BC42EBFBAF751A), extract the .tar and flash in PDA slot in Odin(AP in Odin v3.09+) to obtain semi-functioning(no-wifi) MK2.
3. Use your favorite root method to root MK2, e.g. Saferoot, Kingo Root App, then install the latest Safestrap v3.72(NB1)apk (Download and learn more about Safestrap from this thread: http://forum.xda-developers.com/show....php?t=2448925).
4. Boot into Safestrap recovery, perform an advanced wipe, and wipe everything except ext sdcard.
5. Flash the ROM zip in the "Stock Slot."
6. Press "Home," then reboot into Download Mode and flash the I337_NB1_Stock_Kernel(MD5:A9B3BCD7CA16CB77652516E6117A5B81) in PDA slot in Odin(AP in Odin v3.09+).
so first question is how does one place something in the root of your ext sd card
secondly i honestly forgot how to use odin, dont i need to put my phone in download mode to flash? what is the sequence to put the phone in download mode if so? Does USB debugging need to be on?
also there is a note on this thread - once you have completed steps 1 - 4 below consider flashing the NC1_100%_Stock_Rooted_ROM from Post#3 in the following thread instead of NB1 to obtain the latest firmware: http://forum.xda-developers.com/show....php?t=2730144.
i know you might or might not have written any of these threads but you do have a clearer understanding than i do, that being said in regards to the note above would you say follow all the steps but use the NC1 ROM instead of the NB1 ROM? or Use the NB1 Rom do all of it then jump to the link you provided?

I read a bit. It seems not worth it gonna have to leave the device I get a chance , it stinks because it's for such a silly reason

The guy who I traded my note 2 with isn't willing to trade back. I'm stuck with the s4 it seems. Gonna try to work on this phone today after work . Along the way if I run into issues I'll ask here. Thanks

I just read this http://forum.xda-developers.com/showthread.php?t=2692825 a little bit more. Can you guys tell me if I'm comprehending all these right. So step 2 gets me to MK2 bootloader from NB1 that I currently have. And with the MK2 bootloader I'm able to use the 4.3 root methods indicated in the thread. What's preventing 4.4.2 from being rooted isnt kitkat itself but the NB1 bootloader that came with it through ota, because from the look of it after MK2 "downgrade" I'll still have kitkat?
Step 5, if my final goal isn't just to have stock rooted can I flash a rom of my choice here instead of the stock rom indicated in the thread ? If I am able to just flash another rom in step 5, will I still need the stock kernel in step 6 ? Thank you thank you
Edit: step 3 indicates nb1 safetrap but would I have already "downgraded" to Mk2 tho ?

[Q] Bootloader unlock Galaxy s4 sgh-i337 4.4.2 kitkat

I rooted my galaxy s4 sgh-i337 runing android 4.4.2 today using towel root. It is an apk you install and will root any phone with 4.4.2 or lower. Well I tried flashing clockworkmod but when it restarts a message from at&t comes up saying that unauthorize software is trying to install on phone. So I think that means the bootloader is locked. How do I unlock it so I can flash CWM and perform a nandroid backup. Then I want to install custom roms. I know alot of people were looking for 4.4.2 root for s4 so might want to post another thread about towel root. towelroot .com

I know alot of people were looking for 4.4.2 root for s4 so might want to post another thread about towel root. towelroot .com

You CANNOT install CWM or TWRP. You will need to use SafeStrap recovery. Read up about it, as I have the older Loki bypass and don't need/use towelroot or safestrap.
With safestrap you are limited to flashing Touchwiz based roms. You can flash modems. You CANNOT flash kernels.

There's one partially working Google Play edition rom, but otherwise, no.

This makes me truly sad. I was so looking forward to possibly flashing these ROMS and now...I have to get it my time machine and go backwards lol whenever I find the time to figure the downgrading thing out. Sounds to me like I'll be happier when I do find the time.

There is no way going back to the older bootloader. The only way to go back would be to find an older S4 on eBay etc. with the old BL

All the post below are correct except being able to go back to firmware with an unlocked boot loader.. Install safestrap 3.72 and install recovery. You will get a Twrp recovery .. dont try flashing custom kernels ..It might flash but none of the setting such as overclock etc. will work .nor will you be on that kernel version afterwrds .. I guess the simple answer is no for cwm and aosp roms .. You will be only able too flash custom stock roms

Wifi issues with towelrooted gs4
First off this may not be the right place for this (first time poster), and if so, either please help me in finding the right forum or forgive my ignorance.
I rooted my galaxy s4 today, and I have found that when I am trying to use wifi I am unable to connect to some pages. Using chrome I am unable to load google.com, or google anything directly from the search bar. And the app imgur also doesn't load whilst on wifi, but if I switch to my cell network they load just fine. If I had unlimited data of course this would not be an issue, but that is not the case and therefore I come to this forum and hope that someone can help me out!
My s4 is an at&t i337. I would amazingly, greatly appreciate any help!
Much thanks in advance!

lost recovery with unlocked bootloader
Hello,
longtime flasher here, not as familiar with gs4.
My girl has a sgh-i337 that has been bootloader unlocked since day one. Been on TWRP and slim rom the whole time too.
I was wiping Cache, Dalvik Cache, and System prior to doing a rom update and TWRP glitched out while updating partition after the final wipe operation. Screen went black. Boots to download mode only.Will not boot rom (as system was wiped) but shows the samsung custom unlocked logo. When in download (odin) mode, I see product name: sgh-1337, Current Binary: Samsung Official, System Status: Custom CSB_OEM_LSB: 0x30 Write Protection: enable
universal android toolkit will not show device connected so Installation of custom recovery through toolkit fails. ADB will not show device connected. ODIN will show device connected, though.
To recover with odin, can I flash the I337UCUAMDL from sammobile and retain unlocked bootloader?
Thanks for any and all help.

What is the bootloader version you need to unlock? I have 4.2.2 Red ATT S4, Baseband Version : I337UCUAMF3 / BUILD: JDQ39 , if i was able to unlock how would i go about doing so? I was hoping i could do something with Loki if not? How does Loki work exactly as well?

Congrats, you just voided your warranty. It will be 0x1 instead of 0x0.

I've tried using other methods I'm not home to try this one out but every time I've connected my phone to Odin the COM Port has always been blue, I've never gotten it to be yellow like I've read in other guides. Any time I've tried to flash when it's blue it's failed. Any suggestions to get it yellow?

I believe in Odin 3.09 it is blue I've always used 1.85 where it's yellow. What tar file are you trying to flash?

Hmmm. I still don't know why it fails but when I get home I'll have to let you know. I've deleted several after failing. I'm sure I can find them again and I think I still have a few as well so I'll let you know.

I've used both CF Auto Root, Towelroot, and Motochopper guides and none of them have worked.
The only file I have on my computer is: philz_touch_6.08.9-jflteatt.tar.md5 as one of the files I used but that didn't work. I actually had already downloaded the files from the article you had linked but I didn't get around to it yet, I'm going to try that method out in about 15-30mins and see what happens.

It worked!

Followed everything on that post and it worked! I'm rooted!
Though I'm not sure if you know about custom recoveries. I'm having issues with installing any of them and having it work. I am currently trying Safestrap and for some reason it won't install the recovery. It'll go through the process, but the state of the recovery won't change or anything.
I ultimately want to install CM11, but I'm really struggling to find a way that works!
