How to Unroot T-Mobile Galaxy S3 SGH-T999!

So, you want to unroot your T-Mobile Galaxy S3 SGH-T999 completely back to stock?  Well, I know a lot of you requested this so here’s how to do it easily using ODIN.

Step 1. First, I suggest you to reset the ODIN binary counter by using TriangleAway app.  At the time of this blog post, TriangleAway app does not support T-Mobile Galaxy S3 SGH-T999 but by the time you read this it might be supported so go ahead and download the TriangleAway app apk, install, and see if it works.  (You can download it here on XDA, you will have to register for a username, it’s free.)

redruM ROM for Rooted T-Mobile/AT&T/Sprint Galaxy S3! [SGH-T999][SGH-I747][SPH-L710]

I know a lot of you have been waiting eagerly for T-Mobile Galaxy S3 ROMs and well, here’s my first T-Mobile Galaxy S3 ROM I’ve tried (and not that many out there right now) and glad to say I can recommend this one over the stock ROM. The redruM ROM also works on AT&T Galaxy S3 according to the author (in fact works for any Galaxy S3 with SIM but DO NOT TRY ON GT-i9300!!!). Also there’s a ported Sprint version you can try if you have a Sprint Galaxy S3.

How to Replace Broken LCD Screen on Galaxy S3!

So, I had the most unfortunate things happen to me on the first week that I got the Galaxy S3, I dropped my Galaxy S3 straight down onto uneven concrete from my pocket face-down, which is the worst way to drop a smartphone, and I didn’t even have a case on.

Fortunately, you can buy a Galaxy S3 Screen Digitizer to replace the broken LCD. So I decided this could be an opportunity to make a Blue/White hybrid Galaxy S3 and ordered a Blue Galaxy S3 Screen digitizer for my Galaxy S3.
