Guide back to Stock? - T-Mobile Samsung Galaxy S II SGH-T989

Ive looked around and cant seem to find a specciffic post so ill ask:
I have a couple of samsung GS2 T989 on (Tmo) one of which i flashed to some version(11 I think) of cyanogen mod. Have since moved on from them.
Going to sell them on swappa just to get rid of them, But i think it would be better to flash the modded one back to stock, i think i used Odin originally.
Ive looked around XDA but can seem to find a guide on flashing back to stock. Ultimately, may stock but unlocked may help to sell them.
any direction?
Thanks

Finally rooted my nexus

Now what? I used the toolbox which makes rooting and flashing way more useful then what I was used to with my fascinate.
I'm not sure what to do now. I'd like some feedback about which roms you guys are the best.
Like many of you I've been having issues with my radio, no data network, poor signal etc.
Is it worth flashing a new radio? Would it make much difference or is it not worth it? I'd hate to go so far that I can't get back to stock when updates become available.
Any feedback would be much appreciated.

as long as you don't brick your phone, you can always go back to stock. There's no difference between going kinda far from stock and all the way from stock. Its just as easy to go back.
Definitely try the 4.0.4 radios.
And what the guy above said...
Returning to stock is always the same.
Flash a few images and relock = stock.
I'm currently using AOKP and I've found it to work for me. Radio-wise, I have no clue but everything works just as it should. I doubt I'll see a real world benefit in having a different radio.
Well, definitely do NOT flash CM9 first. Because once you've tried CM9 all the other roms will just be a disappointment. ;-)
But seriously, just try a few roms. There are some really good ones. I prefer CM9 (bugless, fast, and friendly for your battery), but AOKP is also very popular (feature-rich but some more bugs I believe). It's always easy to make a nandroid backup and restore it whenever you want.
Thanks all. After bricking my fascinate twice I became a little gun shy when it comes to mods. The tool box makes it so simple though, I couldn't resist. I'm trying cm9 as soon as I get home

I actually just rooted yesterday to combat my extremely poor signal here in Chicago on T-Mobile. My problem now is I have zero service on nearly every radio now. Tried them all waited 10 mins and rebooted and no signal bars. On 2 of them I can get bars but no service. I have upload arrows absolutely no download arrows. And I'm actually trying to load the market or xda and it just times out.
Edit: Sorry for the thread hijack buddy. Found my exact issue here.

Looking for stock SGS2 Rom

Hey guys, I am in desperate need of some help. I had to have my SG2 replaced because of a bad headphone jack and need to send the old phone in, as always I waited till the last day to try and get the phone back to stock and am running into problems. I have tried to download every ODIN file there is but it seems that none of the file work, I have been on here as well as searching u have google and cant get a "stock" rom that will work. If you have a stock rom that I can ODIN my phone back to stock I would appreciate it if you would send it to me. Getting really pissed at all the dead links and bs files people have posted, I just need to GO BACK TO STOCK..............Thanks for any help you can offer
It doesn't matter as they won't check. They'll send it in to get refurbished and that will wipe it. Trust me on my third sgs2, and the ones I sent in had a custom ROM on them. Never heard anything about it.
Not to sound like and ass but this is not the forum for these requests, general is usually the place.

You need to be stock to use kies, that's his whole issue, he needs to go back to stock, not upgrade from GB to ICS.

What should I do first

Getting my GS3 today, it along with its rock quicksand case are "out for delivery". We all know this feeling.
So my question to you guys is, what should I do first? I've done just about everything to my captivate and am well versed in the rom world but I wonder should I try it out stock first, jump into JB (which will happen inevitably), install some games (if so which?), etc. Let me know what you guys think and some of the awesome things you first did with your GS3.
EDIT: similar thread a couple down, mods can delete this one.
Root it and play with stock for a while..

Idiot mistake and the company that fixed it for me

I made the ultimate mistake the other day. I flashed a kernel for another device onto my S3 and of course paid the price of bricking my phone.
To set the scenario, I had back surgery last Thursday and was released from the hospital on Friday with a supply of pain killers and orders to not do anything. Well, while sitting around doing nothing I got bored and decided to work on a couple of my friends tablets that needed rooting and roms installed. I got them done without any issue and then decided to mess with my phone. There were a couple of new kernels I wanted to test and so I decided to do this. I booted into recovery and selected the kernel and flashed. At that moment I realized that the kernel I just flashed was not for my phone and when I tried to turn on the phone and nothing happened, I knew immediately what I had done and after saying a few nasty words to myself I started searching for a way to fix it. While searching through the forums I kept reading about MobileTechVideos.com and their ability to jtag repair phones. Since I have never had to do this and my phone was not going to work anyway I decided to give them a call and see what they had to offer. I called them and asked about their services and they said that it should be no problem fixing my phone. I live in Dallas and the company is in Bryan, about 3 1/2 hr drive, I decided the easiest and fastest way to get my phone repaired was to take it to them and wait. On Tuesday morning I drove to Bryan and dropped off my phone. When I had called them they told me it might be a couple of hours to fix it, but once I told them it was a tmobile device they told me to wait because it might only take a few minutes. During this time they showed me around the office and I was really impressed. What impressed me the most is that no one working for this comany could have been over 25, even the owner. So after a brief tour of the office, about 10 minutes, my phone was fixed and was ready to go. I paid my $60, which I believe was well worth it, said thank you and was on my way with my fully functional phone.
They never asked me to post anything and I don't have any affiliation with this company. I just want to post about a company that provided the service they said they would at a price that is reasonable since without it I would have a $600 paperweight. So if anyone ever happens to make the foolish mistake that I made and you need your S3 repaired, I would 100% recommend this company. Here is the link to their website, http://mobiletechvideos.mybigcommerce.com, mods let me know if this is not allowed and I will remove it.
I know I am always questioning online companies likes these, but this particular company has earned a customer for as long as they are open and support whatever device I happen to be using. I just hope that since I made this mistake I will hopefully never make it again.
Moral of story: If on heavy doses of pain killers don't crack flash kernels. If might cost you in the end. :}
Never bricked a phone before but I've heard great things about that company. If I ever run to trouble I'll surely go to them immediately.
Thanks for the review.

Hope you're feeling better.

Pain meds after back surgery are a definite yesssssss, just don't brick your phone. lol
Happy to read a ringing endorsement, though - also "just in case".
Hey dude. Im in Dallas too. Good to know. I read all about them. They are really good in jtag fix devices. They were the first ti have s-off on the htc one. They did it after an hour of getting the phone. I havent brick any phones yet but I have their number save just in case. I have seen where they sale the jtag device to do it yourself. It cost about $100 it is well worth it

Good service but more expensive than some.. but local is good.

I'm glad your device is back and operational. Thanks for letting us know about a trusted reputable service.

Thanks. I am not one who likes reviewing companies, but this one time I felt it was justly deserved. I read to many threads about shipping your device to someone and for a cheaper cost they will fix it. That makes me uncomfortable. I would rather pay a little more for the peace of mind. Even then I was more comfortable driving as far as I did, after just having surgery, because of my skeptism. That is why I felt the review was warranted to help someone when they are not local.

I didn't realize your phone would get bricked with a bad kernel. You can't just go into odin and restore the original system image?
Not criticizing here, I'm just trying to learn something. Glad you had a good experience, as I'm sure at some point in my life I'm going to brick a phone.

I can confirm that flashing a wrong kernel will brick your phone. I did that and still not sure if it was wrong one but in did screwed my phone, luckily I exchanged it for another device since I had it for a week.

I have done the same thing. I flashed an international ROM on my T-999. I had also read great reviews people had using Mobiletechvideos. He had mine back to me in less than 1 week. Awesome work. If someone from MTV is on here, thank you!!

It wasn't a bad kernel, it was a kernel for a different device. I was working on several devices that day and put a kernel for a nook tablet into my S3 folder by mistake. Teaches me to only work on one device at a time.

thanks for the write up good to know
Can't you just re flash the entire rom stock or not with Odin or cwm?
I dunno, first time I "bricked" my phone was from an incorrect kernel also. Just downloaded stock touch wiz rom go to download mode and flash with Odin.
I'm not aware that you can brick your phone unless you mess with the bootloader itself.
Bricking means exactly what it sounds like. It's just a piece of useless hardware that you can't recover, in this case, with an incorrect kernel flash, you can, either through another kernel that is compatible with your device or re flash the entire rom; with either Odin or cwm.

When trying to connect to computer it would not recognize the device correctly. So no odin if you can't connect to computer. No flashing anything else if the phone doesn't turn on. That would be as hard bricked as you can get.

Yeah but you can't hard brick it if you flash a wrong kernel unless the kernel replaces your bootloader.
Oh wait, ok I get it. You flashed a kernel that replaces the bootloader also, like with the international dual boot kernel

To root or not to root?

Upgraded from a note 2 to a 3 and I'm loving it. I always root and are coming from jedi roms. Is the note 3 that noticeably better rooted? I've read alot of threads where people have many problems. I genuinely wanna root asap but are hesitant. Someone help push me over the edge to flash land

Ok. Let me push you over the edge. I had never considered rooting a phone until I got the note 3. I decided to root so I could customise the pen widow ap. It has been the best thing that I have ever done with a phone. Yes the note 3 can be a little temperamental when attempting to flash ROMS but there is a lot of support and if you need help pm me and I will help to get you going. Going to put in a plug here for my ROM of choice. JEDI ROMS are good but I have not found a better setup so far than X-Note. Any questions about it and I will be glad to answer. Don't let other people's problems change your mind about rooting. This is a must root device.
Thanks mate, is that compatible with tmobile. I checked thread and it looks pretty sweet. I liked the air command themes. I got some questions, I'll pm you

Totally worth it man. Very easy to do as well. Not only the customizations mentioned above but also aosp roms and such are wonderful. W03 Slim is fantastic!
It's so easy to unroot the phone and go back to stock, so you might as well give it a shot and see how you like it. Unless you're completely incompetent then nothing too bad should come out of it. I personally like having my phone rooted without any custom ROMS. But that's just me, a lot of others would say different.
I am hoping to unlock SIM for a t-mobile phone / region unlock. I understand I can do that by rooting it. Can I root and leave it with stock firmware, and will I get OTA updates? Also, is it safe and easy to unroot. IF it's unrooted, will they know it was rooted (i.e. warranty void?)
Thanks
Rooting doesn't void warranty either. I was skeptical too. Rooted on 4.3 and loving it.

Waiting for my phone. Hopefully it's still on 4.3. So can someone confirm I understand everything all this correctly.
I can root with Root de vega (if still on older firmware) and it won't trigger anything to void warranty. I just want to use region unlock to try unlock the sim/region. After that...I can either unroot? or keep it root. IF I keep it root...but I want the latest firmware (not custom)...is that possible? I've seen video about flashing the firmware from Sammobile with Odin which brings it back to unroot stock...but what if I just want the newest stock firmware without unrooting? Do I need some other recovery and flash something else? Will putting in different recovery cuz the warranty tracker to trigger?
