    Hi I used odin and installed it and rooted my phone bu then I deleted su and I had no root acces so I used odin agian and couldnt get root access help I am a noob in rooting and android

  • MaybeWhyNot

    Seems like I have only rooted my phone (using TUT above) but I dont have CWM on it. Because when I follow instruction on installing a custom ROM, I get a recovery screen but different than what you have in screenshots. Please advise on what to do…

  • MaybeWhyNot

    Well I think I may go with Wicke3d then… Whats the point of having an S4 just to keep it lean and dull :) Thanks for your advice.

  • http://www.droidviews.com/ Rakesh

    Look, if you want to enjoy pure Android without gimmicks or cladding, you can install the GPe ROM, but if you want to stay with Samsung features with optimizations, go for wicked.

    Performance-wise GPe will be faster and more battery-friendly. Feature-wise, Wicked is the best. The choice is still yours!

  • MaybeWhyNot

    Sorry to sound slow over here but want to verify that the rom I asked you about is good for Galaxy S4 m919 (tmobile) rooted on 4.4.2? Or shall I go for Wicked that you rate so highly?
    I am a noob so I am trying to find the best option per my limited knowledge. :p

  • http://www.droidviews.com/ Rakesh

    That’s a good choice to go with. Here is the tutorial: http://www.droidviews.com/how-to-install-custom-roms-on-samsung-galaxy-s4-gt-i9500/

    Okay… love my rooted S4 but my S4 keeps reinstalling some of the Samsung and google apps that I don’t even use. Also can you suggest some strable and fun Roms for my S4 by trusted developers? I tried to look up on xda but its hard to find some credible ratings…

  • http://www.droidviews.com/ Rakesh

    It won’t make any difference.

  • James2014

    Nevermind, thanks for the quick and easy tutorial and for not effing up my phone!!!

  • James2014

    It says RESET! instead of PASS

  • http://www.droidviews.com/ Rakesh

    Glad to know, Doctor! Keep visiting.

  • doctor2014

    Thanks a lot! Unbricked my phone! Woohoo!

  • http://www.droidviews.com/ Rakesh
  • Doctor2014

    I forgot most important part. Before rooting method, I used rooting method for Andriod OS 4.2.2, but my phone is 4.4 and also forgot to enable USB debugging. Two mistakes :( I’ve rooted my phones the past 3 years with no problems. I need help correcting these stupid mistakes. Thanks in advance

  • Doctor2014

    Rakesh need your help please! I’m getting a message top left-corner saying, KERNEL IS NOT SEANDROID ENFORCING, Set Warranty Bit : Kernel. Please help, what do i do? Phone model SGH-M919 :(

  • WhiteTail223

    Confirmed worked for my Samsung Galaxy S4 M919.

  • MaybeWhyNot

    Just wanted to thank you for your TUT. Seems like the problem was with my user account. I followed your tutorial on my administrator account and phone rooted without any hiccups! :)

  • Cameron Dickson

    I’ve tried this twice exactly and it boots into the recovery and does its thing but when it reboots it’s not rooted. Any suggestions?

  • MaybeWhyNot

    Redoing step 1. so far it has been few minutes but Odin is still not detecting anything. Although when I connect my cell to PC “BL” button (one above “AP”) starts to flash blue for a while.. That means anything?

    Phone is still saying Downloading… Do not turn off target !!

  • MaybeWhyNot

    Ok I installed Kies and now I am not getting that driver error.

  • http://www.droidviews.com/ Rakesh

    In Windows device manager? If yes, show me the screen.

    You can also try uninstalling the driver and installing Kies for drivers. Make sure Kies is not open while you use Odin.

  • http://www.droidviews.com/ Rakesh

    Reinstall drivers, reboot computer, enable USB debugging and try again!

  • MaybeWhyNot

    Also I was noticing that when I boot up the way you suggested, my windows detected a different device model number and did not install because the driver is missing? When I boot normally, my windows 7 detects it fine and immediately.

  • MaybeWhyNot

    No it was not detecting my device. I waited for good 20-30 minutes and than just pulled the battery out. It started in regular mode normally.

  • http://www.droidviews.com/ Rakesh

    Does Odin detect your device?

  • MaybeWhyNot

    Ok I followed your step 1 and all my screen is showing now is “Downloading… Do not turn off target !!” I still went ahead, opened Odin3 and connected my phone to my pc but no dice. What am I doing wrong? or shall I wait for my phone to finish downloading whatever it is downloading and try connecting then?

  • http://google.com/+JoeCole_social Joey Graziano

    thank you very much for the links. However, when tried to execute the commands I am getting a permission denied error. Eventually someone will root the ATT kitkat gs4

  • http://google.com/+JoeCole_social Joey Graziano

    I tried the CF-Root for Tmobile and there was no luck.

  • Riley Sullivan

    Is there a method to unroot. I’ve searched the web everywhere, can’t figure it out! I’ve tried downloading the official firmware from SamMobile’s website, but I keep soft bricking after Mobile Odin flashes it in only a few seconds. I don’t have a PC, so I need to use mobile odin. Thanks in advance.

  • http://www.starr-rhapsody.com Jennifer Ayers-Gould

    No idea where I would find the log? I ended up having to do a restore of my phone after trying MotoChopper and Odin to root my phone and soft-bricking it. Now I am back to square one, but at least my phone works again.

  • http://www.droidviews.com/ Rakesh

    What does the Odin log say?

  • http://www.starr-rhapsody.com Jennifer Ayers-Gould

    Followed all directions and Odin3 says “FAIL!” =(

  • http://www.droidviews.com/ Rakesh

    Wait, did you try the CF-Root meant for T-Mobile S4?

  • http://www.droidviews.com/ Rakesh

    Well, there a rounded method, see if it helps: http://forum.xda-developers.com/showpost.php?p=50667360&postcount=1

  • http://google.com/+JoeCole_social Joey Graziano

    Does anyone know if a method for the AT&T GS4 running Kitkat? I tried this article out just for fun and there was no luck.

  • http://www.droidviews.com/ Rakesh

    No, it won’t wipe your phone’s data.

  • Alan Sloan

    Does using this method to root wipe the phone? Wish I had known about the SD card thing before upgrading or I wouldn’t have.

  • http://www.droidviews.com/ Rakesh

    Perform a data factory reset from recovery. Do not forget to backup your data first to external SD.

  • http://www.droidviews.com/ Rakesh

    Yes, you need to wait for about a week till 3-4 charge cycles complete. Let the phone full charge and full discharge for 34 times and put it to charge after turning it off.

  • Neftaly

    battery works great on mine. maybe after the update you need to recalibrate the battery or something

  • Christopher Fonseca

    Ota via wifi on sgh-m919.
    Everything runs great and some of the features are exactly what I was waiting for except for two things. Battery drains ways to fast, off of a full change I got 2 hours on stand by mode. Also the phone now over heats which has never happens before with my device. I really hope Samsung fixes the issue quick as you can go back to your previous is version. So if you update keep that in mind.
