Rooting the Samsung Galaxy S3 - This 8-Bit Life
I have been dealing with a slowly failing OS on my Galaxy S3 for the past few months. I rooted my phone but left the stock Samsung rom installed as it suited my purposes but always intended to wipe and install CyanogenMod or an experimental ROM for funsies. Unfortunately before I could get to that point Verizon pushed out an OTA update and I apparently bleary eyed in the early morning allowed it to push through and overwrite the changes I had made. Nothing catastrophic mind you, I just lost my root access and the bootloader was re-locked. I was unaware that an OTA would do that actually. After that point the performance of my phone seemed to degrade over time. I’m unsure if this was due to permissions issues created by the sudden loss of root, filesystem corruption, etc.
Last night I decided to make a go of reclaiming my phone. Here’s what I did to root from what was ostensibly a stock 4.1.2 install with a few tweaks to the process to make it a bit more user friendly.
- Download the following zip file from my site: SGS3_root.zip
- Unzip this to your desktop or a directory of your choosing.
- Install the SGS3 drivers on your machine if you haven’t already. They can be found here: http://www.samsung.com/us/support/
- Connect your phone to your PC and copy over the files ‘root.zip’ and ‘VRLE6.bootloader.zip’ to the root of your sd_card. Power off the phone.
- Open the directory named ‘Odin3_v3.07’ and run the Odin application.
- Boot your phone in to download mode by pressing the Home, volume down, and Power buttons simultaneously. You should see a yellow triangle now. Press the volume up button to enter download mode.
- Connect your phone to your PC and you should now see a COM port listed under “ID:COM”. **If you do not you may need to re-install your drivers or try the stock USB cable.
- Click the
‘Bootloader’‘PDA’ button and select the ‘VRALEC.bootloader.tar.md5’ file, then press ‘Start’.
- Turn your phone off and boot back in to download mode as you did in step 6.
- Reconnect your phone to the PC.
- Click the ‘PDA’ button and select the ‘cwm-220.127.116.11-kexec.tar.md5’ file, then press ‘Start’.
- Turn your phone off one more time and then boot in to Recovery mode by pressing volume up, Home, and Power buttons simultaneously.
- Select the ‘install zip from sdcard’ option and select the ‘root.zip’ file, once this has flashed repeat the process for the ‘VRLE6.bootloader.zip’ file.
- Now reboot into your freshly rooted stock rom. From here I would highly suggest downloading Rom Manger from the Google Play store, updating clockworkmod, backing up your rom, and then installing something like CyanogenMod.
