DeleteHere steps to root Galaxy S3 (AT&T) SGH-I747
Thx.
ReplyDeleteThe COM port stay BLUE and doesnt turn YELLOW, then after 5 minutes or so i get the FAIL message in red...
ReplyDeleteIm on 4.1.2 (Bell)
DeleteThe successful connection will be indicated by an "Added" message in Odin. You can try to reinstall the usb drivers.
DeleteI'm having the same issue..I have tried doing it on two computers and the ID: COM box will not turn yellow. It recognizes that my phone is connected by saying "added" but the box stays blue and it just hangs when I try to run the process.
DeleteWill This Work On A Rogers SGH-1747M Galaxy S3?
ReplyDeleteShould I Factory Reset Before Rooting?
Factory Reset is not required. It should work on any Galaxy S3 SGH-I747M. Try it and let us know.
DeleteI followed the steps above and all appeared to go well with ODIN returning the message PASS. When I test to see if the phone has been rooted however using "Root Checker Basic" the phone "hangs" (exit with backup key) with the message "Please wait for Root Check to Complete. System appears to be running slow". Starting Titanium Backup and the app never loads beyond the message "Asking for root rights".
ReplyDeleteI have this exact same problem, any resolution?
DeleteNevermind, I figured it out. Go to Google Play store and install SuperSU
DeleteI have the same issue, phone will say it's rooted, but no apps that require root will load past the "requesting root rights" phase.
DeleteTried installing superSU to no avail. Didn't do much of anything except add to the list of apps that freeze "asking for root rights"
wtf?
Can you also give a way to Root Galaxy S3 for international users? I mean is that possible? When I got the news about the S3 in the past, I suddenly thought if this is possible.

Take a look at this.
DeleteAny issues with the WiFi toggle with this root method?
ReplyDeleteI have a Bell SGH-i747M GS3, worked perfectly. Clear and concise instructions. Thanks so much!
ReplyDeleteI have a Bell SGH-i747M GS3, worked perfectly too. Thanks for the instructions. But when I was trying to rename a lowbattery system file, it failed and says I have no permission.
ReplyDeleteAny idea why?
Close Kies before rooting
ReplyDeleteHey, thanks for the root, worked fine , but wifi is now unavailable. Any help please?
ReplyDeleteI found 4.1.2 draining my battery crazily. only 10% left after 4.5 hours, with very very little use. Does anybody else have the similar issue?
ReplyDeleteEats battery really fast... Is there a relatively easy way to reverse the rooting?
ReplyDeleteI don't think it is caused by rooting. I deleted some widgets and seems battery usage improved some.
DeleteIf you rooted your phone with battery under 75%, you may experience battery drain. All you need to do is a battery calibration, there is an app to do this easily
ReplyDeleteI am having same issue as below with my SGS3-I9305 (LTE) :
