How To Fix TowelRoot “Phone Isn’t Supported” Problem

Towelroot is the future when it comes to rooting Android smartphones. Towelroot makes the rooting process a lot easier. Before you had to download different files on your computer, install a dedicated program, connect your computer to your phone and then root it.

Towelroot makes it possible to root your Android smartphone without even having to use a computer thanks to an exploit developers have recently found. The creators of Toweroot claim that this method can root all modern Android smartphones. However there are a few unsupported devices that normally cannot be rooted with Towelroot and every time you try to do so you get the following warning: This phone isn’t currently supported by Towelroot.

The problem is with the modstrings which modify the exploit parameters in order to root different Android devices. If current modstrings don’t support your device, you can easily manually change them and make your phone compatible with Towelroot.

If your phone isn’t supported, when you open Towelroot and press the “Make it rain” button it says that the phone isn’t currently compatible. To change the modstrings, open the Towelroot application and tap three times “Welcome to Towelroot v3” sign. This will open a white box under “Make it rain button” where you have to type one of the following codes.

Code 1. 1337 0 1 0 4 0

Code 2. 1337 0 1 7380 4 0

Code 3. 1337 0 1 0 4 1

The first code is the standard one and should work for most of the devices. If the app says your phone isn’t supported, type the first number and then press the root button. If the first code doesn’t work and you have a Samsung Galaxy device, try the second number.

The second code should work with almost all new Samsung Galaxy devices. Again, type the number and press the root button. The third code is universal. It can root any modern Android device but it is a temporary root. So you will lose root access when you reboot your phone again.


  1. I tried all 3 and it didn’t work either. Running verizon samsung s5. There was a recent verizon update this week that I made the mistake of letting it update. Perhaps that is why? Any known fix?

  2. How do I down grade I have the same issue as Jason along with the same retailer verzion I also have the new update as well how can I downgrade

    • Yes, if you select a very old firmware during the process it will uninstall the update. But keep in mind that it will void the warranty because of KNOX.

      • I think I am taking mine back to best buy to swap it. After this update I am seeing battery life draining faster as well as the camera failure message. Reboot and the camera works again but I don’t feel I should have to do this all the time.

      • i dont understand how to uninstall the update i dont see the right firmware i have sm-g900v 4.4.2 and i dont see it need help
        and what should i do about the country i dont see usa

  3. How long is this supposed to take? I’m on a Galaxy S3 I9300, and using the second code makes the app freeze for an indefinite time. I’ve force closed it and retried, rebooted a couple times, now I’m just gonna let it lie for a bit to see if it goes through with the rooting

  4. Hello, I bought my SGS5, rooted with this tool (thanks to developers) (KNOX 0x0)
    But I did wipe/factory reset and since that phone was saying “it doesn’t work”
    Nothing helped.. But… I tried to flash official ROM from
    KNOX 0x0 after flashing official ROM too…
    Thanks to all who developed Towelroot and good luck to others….

  5. Hello Naldo,
    First of all, you do great work! Secondly, I am posting here because I have been trying to use towelroot but it keeps saying “device not currently supported”. I received my Verizon S5 just yesterday after it was repaired by Samsung. It was rooted before and mistakes were made when it was and so I had to get it repaired. I would like to have it rooted once more. Can you help? Thanks.

  6. Hello all, I have a galaxy s5 active from att, and I have tried all the midst rings and still getting “phone isn’t currently supported” any idea would greatly be appreciated

  7. I have a galaxy star plus s7262 and the date of kernel is April 21. It is possible that towelroot work on my device? (I will not test now because I’m at work, hehe)

  8. I tryed All options and it says this phone is not supported. I own a quad core pendopad [cheap tablet $80 australian, bought from target] running android 4.4.2. i want to root this so i can play around with it. Does anyone know how to fix this app or another one i could try?

  9. I have tried all 3 codes and none of them work. I have a Samsung Galaxy Tab 3 with a kernel that is before June 3rd so it should work but it doesn’t, help?

  10. My kernel is Thusday ,Feb 28 and my android version is 4.1.2 and its shows phone not supported ,when i click quickly a few times ont the name nothing happens :/

  11. it says my phone isn’t currently supported…before it worked… but because i updated my phone with the new Baseband Version – I747MVLUFNH2 – it doesn’t work…. i think this is the latest update still 4.4.2 tho

  12. it says my phone isn’t currently supported…before it worked… but because i updated my phone with the new Baseband Version – I545VRUFNG6 – it doesn’t work…. i think this is the latest update still 4.4.2 tho

  13. Was working two days ago on my galaxy s4. But after my phone updated when I connected to wifi I can not get it to re root. I have tried the three different codes and several others trying to get it to root again. Any help would be appreciated. The phone is a Galaxy s4 with AT&T.

  14. It dosnt work on my galaxy s3 with 4.3 my kernel is jan 20 2014 but still phonee not supported

  15. I have a Kindle FIre HDX 7, was following a video, but to the error message that my (not) phone was not supported. tried all the codes. any thing else i can do? thanks.

  16. Hi !!! I can’t root my device with this rooting app. It appears “Phone isn’t currently supported

  17. Thanks a lot….I put in the third code on my S4 and it still says it’s unsupported.

  18. How weird. I am on a Samsung S5 and when I try the second code my towelroot just becomes unresponsive and forces me to close it.

  19. Not as simple as that. Geohot himself explains how to play with those numbers, and if you are willing to, eventually you will be able to root it. But there is many numbers to go through and my device froze trying the first one here.

  20. Hi all, do you know if can i root my cellphone with towelroot, if my note 3 have android 5.0? it said not supported..


    • I’m not sure about the Note 3 running 5.0, but the Verizon Galaxy S5 running 5.0 cannot currently be rooted without downgrading to Kitkat 4.4.2. I recommend reading threads in the various Android forums to find a solution to your problems. I did a LOT of reading to find my solution, but you’ll need to find some answers that are specific to your device.

  21. For anyone planning to post a “won’t work, help” comment, yes, it won’t work for newer kernels dated past 2014 June. Geohot is working for Google now so towelroot will never get updated, and either you root it the hard way or you flash an older ROM.
