    Hi Max,
    Quick question…
    After rooting using motochop, upon rebooting at start up there is a lock with the word “custom” under it.
    same as where/when the triangle was.

    do you know if there will be a “lock away” or will unrooting and resetting the phone get rid of it?

    Thanks,

    Kris

      Hmmm it seems like you didn’t install the kernel, try re-installing kernel in CWM, if you have kernel installed correctly, you shouldn’t be getting that message.

        Hi Max,

        I also have the same problem with the unauthorized software warning. Chris directed me to your youtube video. I followed your video exactly including downloading the kernel and installing it after I installed the ROM. Everything seems to work until I reboot and get the same warning. Any advice?

    I am extremely new to “ROOTING” and the Droid life. I have been limited to the iOS world for years and am now taking the leap to Droid. I live in the Cayman Islands, so I bought an unlocked Samsung Galaxy S4 I9505 new through Amazon, USA. I love the device, but so many of the APPS I want are not available in my region. It seems I need to “ROOT” the phone then use some form of “market switcher”.
    I downloaded the drivers as the video has indicated and also the motochopper. My concern is that I want to be able to revert back to having the phone unrooted after I install the apps I am after. Not sure that is necessary, but sounds like it in order to install future OS updates. How do I get it back to the non-developer state or unrooted stage where it started? My phone isn’t pre-loaded from a carrier like; T-Mobile, Sprint, AT&T or Rogers. Any guidance you can provide would be greatly appreciated.

    I am curious if you know of a way to remove device encryption on the S4. I’m currently downloading the stock ATT image in an attempt to get back to where I started (currently rocking Google’s 4.3).

    Reply
    1. Brian B

      To answer my own question. I was able to use the Odin method to reflash with stock ATT rom. After that and a wipe I was able to access the phone without issue. From there I did the normal steps to re-root it and install the Google rom back on it to get back where I wanted to be.
      If you want encryption just be sure, and remember you will be forced to use a PIN or Password to unlock.

    Max – I haven’t commented on any posts yet but wanted to sincerely thank you for all the help. I was an iPhone user until October of last year. Now I’m not only an Android user but have rooted / custom ROM’d my Samsung Galaxy S3 and S4 phones many times. Even my most hard-core Android friends now look to me for advice and help and even when I point them to galaxys4root.com they still insist on help. Couldn’t do all this without you. Thanks for everything you put into the website and YouTube vids. Appreciate you. Chris, Houston TX, AT&T GS4 Google Play Android 4.3 ROM

    I enabled the AWS frequencies on my Fido Galaxy S4 (Canada) for Wind mobile using your instructions. It worked. Thank you. However, I now have a problem, I received a software update and accepted it and now I am unable to register on the network. Also, I am not able to access phone.util, as when I dial *#7284# it either says cannot register on network or invalid IMEI. I would appreciate some guidance.

    Max,

    I am trying to get high on android but kind of stuck with a question….well questions. :-)

    I purchased an S4 that is US Cellular (don’t see you mention a lot about them) but my current network is with Verizon. What are my option to get the phone to work on Verizon?
    * could I simply just transfer the sim card from my old phone (Verizon) to new S4 (US Cellular)?
    * If not, could I flash the S4 and change it into Verizon S4?

    Thank you and looking forward to your reply,

    i have the at&t samsung galaxy s4 SGH-i337 and would like to root it. ive followed all your directions for using motochopper and get an error about the binary needing updated. the baseband version is I337UCUAMF3 and the build number is JDQ39.I337UCUAMF3. also your guide mentions using the loki method which requires the phone to be rooted. id appreciate any help you can give, it seems that im not the only one having this issue but havent seen an answer about how to succeed

    Reply
    1. Eddy

      Hey everybody. the at&t ota update (Baseband = I337UCUAMF3) kills root, kills custom recovery, it also prevents you from using Odin to flash and previous versions of stock. Two days ago I was rooted with a custom recovery and going back and forth flashing custom roms and using Odin to get back to stock, yesterday while i was on stock, i did the ota update. when i got home i went to go root it again and it failed, i tried multiple ways, keeps failing. it actually flashed SU but it is not properly rooted. So now i have stock I337UCUAMF3 with a broken SU that i had to disable and hide because it was annoying me. from all of my research there is currently no way to root I337UCUAMF3. if your using a version with the baseband I337UCUAMF3 that is why you are experiencing problems. :(

    Hi Max,
    I’ve come upon a couple of issues I was hoping you could educate me about. My current phone is the sph-720, rooted/stock rom.
    First, issue is not that big of a deal but occasionally my phone’s screen will change to an all blue screen that has a white fillable bar across the top and says “cisco” under it. Typically I can just back out no problem but it has gone one step further on a couple of occasions where it goes to another screen asking for a password. Again I’m able to just back out and move on but wondered what this was.
    Second, & bigger issue is that Sprint is on to me & my use of a hotspot mod. I wasn’t sure if you’d want this discussed in public. But I have questions and any advice would be helpful. You have my email on file. Thanks, Angie.

    Just received my new S4. My old one only 1 month old which was rooted was rebooting 4-5 times daily. So I have the new one-it is the SGH 1337 android 4.2.2 I backed my prior one up in Wondershare. My question is I would like to root the new one and restore my old apps. For a fee if you could step me through it I would be gratefully appreciated. Also, I need to send back the old one how can I restore it back.

    S3 Battery “can” be used with S4

    If you have spare S3 batteries you can use them in your s4,
    line up the battery to the far left, it’s the same height and will securely lock in if you line up the prongs to the battery
    you’ll have space on the right of the battery, but notice how it lines up nicely on the left!

    when removing the battery, do as always, don’t pull up where there is space to the right of the battery…
    pull from bottom of battery where the notch is.
    each S3 battery will give your S4 an additional 2100 mAh of juice as a spare!
    Not bad when you think about it… 4,700 mAh of juice in total when combined with the stock one 2,600 mAh S4 battery.
    keeps the slim look without having to go to the horribly ugly extended batteries and their over sized battery covers.

    I have the Galaxy S.4. I was rooted before with no problems on stock rom. I have unrooted and rooted this phone 3 times. I got tired of the install update icon sitting in my notification bar for the last several months. So I unrooted my phone. Then did the ota updates. It was 3 or 4 of them. I am now 4.3 stock rom. So I when to re-root and got that with no problem. I used the odin method, I used odin again to install clockworkmod (v6.0.4.4) on the phone. I rebooted and it worked great, no problems. I then when to get the final piece of the puzzles so to speak. I downloaded MDCHotspotmod-odexed from “galaxys4root.com” to gain control of the native wifi tethering abilities. I when to clockworkmod and flashed the zip file to the phone and it said Installation complete (and cleared both cache before hand) I when to reboot and I was prompted with a message from clockworkmod saying “Root access possibly lost. Fix? THIS CAN NOT BE UNDONE” so I avoid the prompt the first time and accepted the fix the 2nd time and now my phone is stuck in boot loop. With options had me still stuck in boot loop.

    Hi Maxx, just want to thank you for all your hard work. I have rooted all of my phones and many of my coworkers phones all from your tutorials. I would say im in the range of rooting 200 phones from over the years. I like samsung so if i ever do a custom rom i stick to the factory like roms. I miss your roms, when you going to put out some more?

    Hi ZedoMax

    The first question is are you high on android???? I am! :-)

    Next question, I have just had delivery of a galaxy s4 which has 4.4.2 on it and has Knox installed and is currently set to 0×0. I am aware if I root i could change this to 0×1 which maybe an issue with support from Samsung, apart from this is there any other disadvantages that you are aware of that could affect rooting and putting custom Roms on my phone?

    Big shout to you mate all the way from Birmingham, England UK. Keep up the excellent work and stay high on android…

    Hey Max,
    Just got my Verizon GS4 rooted, thanks so much. My next question is about cyanogenmod. I wanted to install it but their web site said it only worked with a certain build #. Mine end sin 1544Vrufnc5. Since I am new to rooting and only know enough to get myself into trouble I figured I would ask you. Is there a version for this build or another ROM that is close to stock android.( I really don’t like touch wiz) also I have not installed safe strap as of yet. Just removed some bloatware.

    Reply

      You cannot install AOSP ROMs like CM11 on latest bootloader with Verizon GS4, only if you rooted on previous versions. BUT you can try ROM like Eclipse ROM, which is TouchWiz-based with AOSP parts.
