However if you’ve not yet updated your device so far, just follow the below link to update in manually.

Update Galaxy S3 Neo GT-I9300I to KitKat 4.4.4

Any Android device, may it line-up among the premium devices or just falls in the regular category needs to be rooted to get the most out of it. Rooting gives access to the unreachable depths of Android awesomeness which is not possible on non-rooted device. The TouchWiz interface from Samsung is beefy consuming a huge chunk of your device’s resources which might be visible while playing graphic intensive games. Rooting also unlocks the door to some beautiful apps which won’t run on normal devices.

    twrp failing to install custom zips on my neo gt l9300i can someone help me

  • Blixen Burke

    Hello, Naveen, how are you? You say this procedure worked on your i9300i phone, using TWRP, so you didn’t get any “Failed” message when flashing the ROM? Cuz I followed the procedure on xda-dev and TWRP fails to flash the zip, to which they advised me to use CWM, but it won’t install on my 4.4.4 stock S3 Neo. I will try again using your procedure. Cheers, brother!……….. i am havin this sam problem twrp fails to install custom zips

  • Okay, do this:

    Install TWRP again, but this time uncheck the Auto Reboot option in Odin. When TWRP is flashed, unplug the cable, pull out the battery, wait for 20 seconds, reinsert the battery and reboot the phone into recovery mode using Volume Up+Home+Power. You would get into TWRP. Try this and let me know.

  • Hello David,
    I see you have trouble with TWRP on your S3 Neo GT-I9300I. Could you please capture and share with us, the complete message displayed in the TWRP flashing screen? This will help us understand the error better and also, make sure to try and flash another ROM (different from the one you currently flashing). Report back to us and we’ll help.
