  1. Hi Jayce,

    seen you have HTC one X and Samsung S3, would you mind post comparison for these 2 unit. I mean the feeling of both phone not the spec wise (which can google around). something like using the 1X/S3 in pocket, how it feel? or use for long hour, does it feel hot and uncomfortable? and the handling as in malaysia hand, how does it feel when holding it? 1 hand or 2 hand have to be use? when driving, does it feel ok?(you know what mean as in malaysian, we do write/read sms when driving or make call)


    • Both of them are almost the same in shape. So handling is the same too. One hand is okay to navigate it but only reach 70% of the screen with my thumb.

      HTC One X is hotter while playing 3D games, surfing Internet.

      I don’t text and drive. No idea. No problem to make / receive call.

  2. Hello Jayce,

    In the video you had a pebble blue wallpaper which is neat, where did you get that, tried to goggle but no joy.

    Can you share.



  3. Hi Jayce
    After rooting my s3 the battery drains fast without heavy use
    please any idea to solve that. I will charge today night and the next day evening it has left only about 17% of remaining battery without heavy use.

  4. I’ve just installed a firmware however, it asked me for a sim network code which i do not have. if i unroot it, will i have the previous firmware before i rooted my phone? galaxy s3gti9300

  5. Hi Jayce, I want to unroot my samsung s3 but when i got to the procedures you presented, it only stucked me for hours on “downloading…. do not turn off target like”. Your video presented like it only takes seconds to that process then how come mine takes more time. Do you have any idea what went wrong? Thanks

  6. Hi thanks for your reply. I thought, my device has already been bricked (not sure). My phone won’t boot up anymore, all I can see is a splash logo of samsung then the language screen wherein you set up your device (same screen when you unbox your device the first time you open it as I was able to wipe data/factory reset it thru recovery mode but still nothing happens). When it gets to set up language screen, my phone suddenly hangs & can’t do anything about it.) I triend every possible means, flashing & unrooot using SGS3 toolkit via odin but still nothing happens. A bit worried though.

  7. I did read it but my phone doesn’t have an installed triangle away apps. Is there a way to download it since i can no longer boot up my device successfully? From the time i turned it on, only a samsung splash logo appeared but after that it stucks to language screen (it’s like setting up the phone for the first time), but whenever i pressed language bar, my phone hangs.

  8. really, thanks i was kind of freaking out by this thing. Anyway, do you have a firmware? ‘was thinking if you could send me a coorect firmware for my phone blg no. IMM86D.I9300XXBLFB.. I bought the phone in the PHilippines but currently I am here in algeria. Here’s my email address Thanks a lot

  9. Hello, i am confused on how to unroot even after seeing this video. I don’t get which firmware to download (i have the one from t mobile and Sprint) but i don’t know which firmware i should download for these phone. I’m afraid that i’ll choose the wrong one and ruin my phone. can you give a feed back on how to choose what to download ?

  10. Hey Jayace

  13. Hi jayce,
