The smartphone sports a powerful 1.2 Quad-core processor, 4.7-inch IPS display with 540×960 resolution, 2,460 mAh long lasting battery. In terms of software, it runs Android 4.4.2 KitKat OS with amazing LG’s features such as Knock ON, Guest Mode, QSlide, Quick Memo, Plug&Pop and even more.


As we said earlier, this smartphone has a great software and hardware specs, but for those who want more, you can get the most out of this phone by obtaining root on T-Mobile LG Optimus L90 (D415).

Fortunately, gaining root on T-Mobile LG Optimus L90 is not too hard to do, thanks to geohot for creating an awesome app called TowelRoot. This phone is one of the dozens of Android devices which managed to get superuser access with the help of this one click root app. Not only T-Mobile variants (D415), it should work on other models too (D410, D405).

  • LG Optimus L90 (D415, D410, D405) running KitKat.
  • Download an apk file of TowelRoot app, it’s only 100KB.
  • Get SuperSU by Chainfire, it’s a superuser management app.
  • Enable Unknown sources on main phone settings, since the ‘towel’ app isn’t available on Google.

  5. After su installation completed, your phone is ready, and your T-Mobile LG Optimus L90 (D415) should rooted now.

    tmobile’s new update patched the root exploit. Towelroot is no longer supported. DO NOT INSTALL TMOBILE’s New Update thinking that it is LOLIPOP. IT’s not!! You’ll unroot your device.

    I just went through all the procedures to find that this no longer works on the L90.
    I would happily donate some funds if this would work on my L90.
    If there is anyway to fix this, please…

    Apparently, only way to root L90 D415 with newest software is to downgrade to the earlier software by flashing the entire system, using a KDZ file of the earlier software, see
    also, xda forums, see thread titled guide-root-l90-varients-updates-t2928364 and [REF] LG Optimus L90 Ultimate Thread, 2770938
