For this week’s ROM of the week for AT&T, T-Mobile, Canadian, and GT-i9505, check out BobCat ROM.

Based on GT-i9505 firmware, BobCat ROM brings you a custom theme with lots of customization.

UPDATE: BobCat ROM version 5.1 is OUT, CLICK HERE to see it instead of this!!!

First, BobCat ROM gives you native hotspot tethering (since all GT-i9505 ROMs support this out of the box) and I had not trouble using it on T-Mobile without any tinkering (and also 4G LTE working fine).  Also you will be able to easily move your favorite apps to SD card since this ROM comes with firmware that supports the latest App2SD by Samsung.

Second, you will find a load of add-ons/MODs through its UpdateMe ROM app found in Settings allowing you to download the removed bloatware, install 3MINIT framework (for additional UI mods), change dropdown graphics (default is blue Android Andy guy), install new apps, and lots more.

Third, BobCat ROM brings you UI customization through Nottach app, which allows you to customize everything from status bar, battery icons, lockscreen, and even enable Volume-up flashlight when screen is off.  (You can also get this app separately for most S4 custom ROMs btw, see here.)

Overall, this ROM is packed with lots of features, apps, and only your imagination is the limit to how much customization you can do to your S4.  If you are looking for such a custom ROM, definitely check out BobCat ROM this week(end) and do let me know what you think!


Download Bobcat ROM for Galaxy S4 (AT&T/T-Mobile/Canadian/GT-i9505)

For AT&T, make sure to install after installing ROM!

For T-Mobile, you will lose Wifi-calling as this is a ROM based on GT-i9505!

If you have trouble installing, try formatting /system and /data and re-install ROM.

    Link now working as of 22nd July 13 @ 21:26 Hrs(London Time)

  4. Tsunawmi says:

    Link is working fine for me although the rom seems a bit buggy with the play store, tells me the app is not installed sometimes and then “google play store has stopped working” other times. It does open the play store and let me install my apps so this is a tad confusing, everything else is working fine so far. On first boot it stays on the Samsung screen for quite awhile so don’t freak out just give it time.

    Awesome ROM.

    Just installed it without even having to wipe anything.

    Just got my apps, settings, toggles and all modified, beautifully without having the work of installing all over again.

    Thanks Max, you rock my friend. The developer rocks too. lol

  6. saul says:

    thanks for your hard work max

  7. J says:

  8. J says:

    Not getting LTE on my galaxy s4 from T-Mobile with this ROM. only 4G

  9. Tsunawmi says:

    Anyone know how to apply the new drop down pics?

    • Max Lee says:

      Reboot into recovery and you can flash the zip file, it will be in a directory but I forget what it’s called.

  10. HR says:

    Hey Max,
    How do you disable the home button from turning on the screen on the T-Moble Galaxy S4?.

    • Trevor says:

      You have to go into xposed install update at the top when your in xposed it has two options framework and modules after you install update click modules and select the ones you want to use you will want nottach for disabling home button wake up after you have selected the ones you will be using reboot then go back but go into nottach find framework and almost at the bottom you will find your answer

      • HR says:

        I am a little lost, how do you get to exposed? is exposed an app or it is in your ROM? . I am using WanamLight ROM. Thanks

      • T says:

        Sorry you are posting on this page for the bobcat rom I don’t remember if wanamlight has that option but xposed is in settings,my device, sconcauteam mod this is a setting that was installed with bobcat rom for customizing your rom but either way you should change to bobcat it is far far far better then wanamlight I thank

        • HR says:

          The only reason I did not flash BobCat, it dose not support wifi calling. However, if is that good I will flash this ROM. Thanks

          • HR says:

            Will, I flashed BobCat. But Xposed, Nottach, and the other features of the ROM do not work for my device. It says these are made for AT&T Galaxy S4, and not guaranteed to work on other device. Is your device is T-Mobile or AT&T?. Thanks

            • T says:

              Yes I am on t mobile and it works flawlessly I havn’t even experienced a single bug I did not have to wipe or anything I have 4 g lte tethering Wi-Fi and all no probs what so ever I am not sire as to y you are unable to use those features I would need to know more about what you have done with your device

              • HR says:

                Thanks for your help, but I found another ROM which is specifically designed for the T-Mobile and every thing works perfect. It is called INFAMOUS S4. You may want to take a look at it:
                If you get to flash this ROM, you may need to install the “white dialer” with it (looks better).

  11. J says:

    I have the tmobile s4 and installed this rom, however I am unable to get my sim to work. it does not recognize any sim card inserted. Have already wiped, reset, reflashed. I’m out of ideas.

  12. Bob Howe says:

    Since I flashed the Goldeneye3.0 ROM from XDA’s iB4STiD earlier this month, since it’s so clean, smooth and fast, the only ROM I’ve been able to consider is his Goldeneye4.0. And it’s damn near perfect, since with a couple tweeks I’m now getting 15.4M TMo download speed on Net10/TMo on my i337. Added back selective Sammy bloatware, transparent weather and clock via his addons as well. You should check it out. Usual disclaimers, JMO, YMMV.

  13. Alex says:

    Hey, I LOVE this ROM, great job Max! I flashed the ROM, then loki-doki and it booted up just fine for the first time. When I tried just a plain old reboot my phone would stay on the first boot screen with Samsung on it. Any help would be great! Thanks!!!!!

  14. Tsunawmi says:

    I updated to the 4.1 version of this rom and I can’t seem to sync my contacts at all, I also had to choose ktweaker to get wifi working at all. Does anyone know a way around this nonsense with the contacts?

  15. Tsunawmi says:

    so when you update the rom to 4.1 you need to check the box for google snyc in aroma installer.

  16. Jaime says:

    Since i installed this rom , I keep losing my call service. I’m on At&t galaxy s4. Any suggestions??

    • Ryan says:

      This has been happening to me non stop as well. I even had to go get a new sim from AT&T just to make sure it wasn’t faulty, and it wasn’t. It still keeps happening :/

  17. Rj says:

    I have a GT-19505, loaded with Bobcat ROM v4.1, everytime I boot or reboot my phone, The message ‘Android is Upgrading” displayed after bootanimation… How can I fix this…

  18. lonewolf says:

    I installed Bobcat 4.1 on my S4 GT-i9505. Why does my phone keep updating apps everytime I reboot even if I did not update the apps?

  19. Max Lee says:

    latest google play store has auto update on by default so just turn it off and reboot phone.

  20. Keegan says:

    After installed update 4.1, i lost WiFi, can’t seem to get it back. How do I go about doing this?

    • Brootis Rinzler says:

      This happen to me as well (lost WiFi). In addition, my micro SD Card will not mount to my S4 any more. Any suggestions for either, any one, let me (us) know.

  21. Nate says:

    I have an AT&T Galaxy S4 (sgh-i337), and I’ve read this :

    Step 1. Download appropriate ROM file for your Galaxy S4.

    IMPORTANT: MAKE SURE YOU’VE DOWNLOADED A COMPATIBLE ROM FOR YOUR GALAXY S4 OTHERWISE YOU CAN BRICK YOUR PHONE!!! E.g. If you install GT-i9505 ROM on AT&T Galaxy S4 SGH-i337, you will BRICK YOUR PHONE! I’ve had many people who DON’T FOLLOW DIRECTIONS who’ve bricked their $700 phone, please do not end up being one of these people. Double-check the ROM and triple-check that the ROM you downloaded is COMPATIBLE with your Galaxy S4!!!

    This says it’s for [AT&T/T-Mobile/Canadian/GT-i9505] S4’s. I obviously don’t want a bricked phone, so I was wondering if this actually is a safe ROM to flash on my sgh-i337. Thank you for any input.

  22. carl. S says:

    the zip files for downloaded drop down menu change are in sdcard then file called update me.

  23. Lucas says:

    Got the rom, really great! But i don’t like the theme, i like the stock theme better… Can i have it on this rom?

  24. Taha Hasan says:

    Can’t seem to enable LTE, its only on 4G everytime, even after flashing the as stated on xda developer forum’s website. Any kind of help would be much appreciated.
    Galaxy S4 – Tmobile.
