Samsung Galaxy S3 (I9300) A possible solution(?) for frequent freezing/hanging

Off topic

I hardly ever dealt with another post addressing mobile phone(s) or technology through this BLOG. There are thousands of bloggers, forums doing it already Smile

I was given a Galaxy S3 (i9300), almost bricked phone a week back for doing some sort of researches and I was forced to return it to the admin department within next couple of hours as I found it was ridiculous to waste my time on a device which was JUST hanging without any reasons

However, after reaching home, I couldn’t just get rid of that “giving up” on certain something without putting reasonable efforts. So I got back to admin, asked them to return the device and started with my experiments.

Now, if you call 30+ hours without a single hanging/freeze is impressive, this is what I have achieved.



Into the details

Please note, if your device still under warranty, try to get hold of a new device as replacement. Follow the exercises described below only if YOU have already decided to scrap your Samsung Galaxy S3

  1. Take super user access on your device (root it)
  2. Download & update your phone with a custom firmware (One which is higher than the one already installed on your device) Check for one
  3. Root again with the latest firmware a second time
  4. Download the original stock firmware from
  5. You should know the CSC code for your device *#1234# (prior rooting itself you should get this code noted down somewhere)
  6. Root again with your stock ROM
  7. Restart, configure & check for updates. One update varying in size between 50-55MBs must be available.
  8. Install the update, if your phone freeze during the download or update, just don’t restart it!!!!! Just leave it idle and get back to it after few hours

Your phone must be showing you an updated status and after few restarts you would find your phone is back to action, without getting into nasty freezing loops (minimum in my case)

Side Notes:

  1. Keep your wireless options always on (recommended at many places and turn off using Wireless for GPS)
  2. Install TrustGo security suite, AVG or Avast free mobile antivirus solution & keep your device balanced and protected

  1. Hi Admin

    The best way is to install cwm(clock work mode) recovery and reflash your fone with cyanogenmod. We will get the original android with many features.

    The firmware comes with samsung is modified by samsung. So the device will be very slow.The original os has nearly 100 unwanted applications and the firmware size will be approx 1GB. But in case of cyanogenmod, the firmware size is only 300 MB

    I used to promote CyanogenMod and i am happy with that

  2. HI

    for Custom ROM’s :

    for Custom recovery mode :

    For Root :

    above links are applicable for almost all android phone/tablet . :)

    rooting and installing Custom recovery mode will take less than 1 min. usually we will get combined packs from internet,

    once we install Custom recovery mode, we can install any ROM, we can backup/restore current ROM ans we can do dual boot also

    for any help : ben (at) – +965 – 5 0 6 2 9 8 2 9
