Galaxy S3 help - General Questions and Answers

Just was looking for a quick answer I haven't been able to find. I just upgraded to the Telus variant of the S3 (i747m) and have rooted and installed TWRP. I just wanted to clear one thing up. When I was using my S2 (t989-d) It was ok for me to use a t989 rom despite using the Canadian variant. I was wondering when looking for a rom which ones would be compatible? I noticed the AT&T variant is i747 and I wanted to make sure I asked before destroying my phone.
I appreciate any answers, thanks.

[Q] Can I install a custom ROM on a network locked Galaxy S2?

Hi,
simple question I assume but I couldn't find an easy answer with Google:
In my family we have 2 Samsung Galaxy S2 phones, one is unbranded and the other is a locked one from Vodaphone.
On the unbranded one I installed the LiteningRom 3.2 and speedmod K19, all works perfectly and battery life is excellent.
Question is: can I also install this (or any other) custom rom on the Vodaphone branded Galaxy or will it brick the phone/make it unusable ?
Thanks in advance for your views.
Hi,
I'm fairly new to rooting, my galaxy S2 is locked to O2, I managed to root my device with no problems at all using ODIN. Just make sure u download the right rooting package for your firmware.
Yes you can! I've done it! My sg2 running a flawlessly rom now.
Sent from my GT-I9100 using XDA
Thanks for the replies, I will give it a try.
Your phone being network locked, to the best of my knowledge, should have no effect whatsoever.
What you NEED to watch out for is whether or not your provider's network is GSM or CDMA. Don't try to flash a CDMA rom to a GSM phone, or vice versa.
And make sure to Nandroid Backup!(!!)

Galaxy S3 (US) root/unrooting

I was able to root my Galaxy S3 on AT&T with the original post/instructions. Works like a charm. But I think I've got a shoddy battery...battery life is terrible. Would like to bring to a store to replace but I can't find a way to unroot? All the previous posts RE: unrooting seem to be related to international versions. (i9300)
I assume the method would be the same, I've got the firmware from sammobile.com. But the triangle-away app doesn't work on the AT&T version it seems. Any help to unroot the i747 temporarily so I can talk to AT&T would be appreciated!
Thanks!
use this program called unlock root, its quick and easy
doesn't look like it supports Galaxy SGH-i747 yet, at least from the website.

ParanoidAndroid ICS ROM for Rooted Galaxy S3

hows it going i hope i am posting to the right place i have very new here to this site. i was actually just wondering, i have the US version T-mobile samsung galaxy s3 and i just rooted it yesterday and flashed cm9. my question though is can i flash "ParanoidAndroid ICS ROM" to the tmobile version. i have noticed on all the videos and posts with this rom it is all the international "i9300" if anyone can answer me that would be awesome that rom looks awesome. i just wasn't sure because of the kernel and when i had my gs2 tmobile i accidentally flashed an international rom to that an totally bricked it. so just being careful this time. seeing how i bought this one outright. but like i said it would be much appreciated for a replay.. thanks ... I'm also not sure how to check back for a response so I'm going to leave my email address [email protected]

[Completed] Looking for AT&T S4 I337 OTA update for 4.4.2 to 4.4.4

Recently switched from Sprint to AT&T. I have been using a S4 I337. I am happy with it. Rooted it. Not happy with volume but I am happy. Bought another for my wife but it had 5.0 on it. I had tried that but did not like it. I used ODIN and flashed hers but it has 4.4.2. Would like matching phones ( I have a touch of OCD). Seems I can't find the update. Does anyone have it or know where
(link) ? I thank you ahead of time.

Samsung Galaxy S7 (SM-G930R6) root?

I purchased an unlocked SM-930R6 today but I can't find anything on it. It's currently running 7.0, but I was wondering if anyone has came across any development for it?
I can't even find stock firmware anywhere. Even if I can't find a custom recovery or ROM, I would still love to achieve root.
Any help would be great!
Thanks
