[Q] Updated samsung s3 i747m to 4.4.4 slim and can't downgrade - Upgrading, Modifying and Unlocking

So to start I went from my s3 to the Z2 when it first came out. I am with bell and for some reason they are not supporting updates and my Z2 is ridiculously glitchy, i'm looking to update the firmware and expect to take sometime to do this and i dont like downtime. Due to some legal reasons my old s3 was confiscated... so i picked up an S3 off kijiji. Unknown carrier but still I747M. I rooted, unlocked and ran cm on my old s3 so i figured i would give this one a rip and see what had come out.
Without thinking i found slimkat and rooted and updated to 4.4.4. Great rom, kind of glitchy, but smooth.
And then i through my sim in... didn't work. So i started trying to unlock it. And my quest begins
I have CM11 boot
I tried the easy modem dialer fix. didnt work
I tried the sim generator, couldn't find my nv data bin file
I then tried downgrading to 4.3 and 4.1.1 stock roms and also mod roms didn't work. Got them off of sammobile and also xda as the sammoblie one didn't work.
What are my options? should i just put this s3 back into the realm of kijiji?
Any help would be appreciated

[Q] Help install Stock Rom issue via Odin

Hi there!
I have a Galaxy S3 SGH T999 version. It has Tmobile rom, but I am trying to install windmobile stock rom via odin (3.07 - tried other older versions) and it fails the secure check.
Is there way to resolve this? I really want to install the stock windmoile rom , and did lot of searching and couldn't really find a lot of info, except that someone with AT&T galaxy S3 had same issue when installing Rogers rom.
I would really appreciate it, thank you!

If you continue trying to ODIN flash firmware which is not intended for your specific phone
you will end up with a nice shiny brick sooner or later, in your case it will be sooner.
If you want the appearance of a windows phone, the best way to do it is to find themes and
launchers which make the phone look like a winmobile phone.
There are a lot of themes and launchers at the play store which do exactly what you are looking for.
Check it out B4 it's too late..
It's not a windows phone style, I think you misunderstood me.
I just don't like T-mobile rom and its bloatware. The windmobile rom is more clean.
Both phones models are same, exact. I don't see how it would be bricked. It's just a mismatch of bootloader, thus secure check fails. I've seen people with windmobile SGH T999V flash T-mobile rom, and it works perfectly.
It's just SGH T999 tmobile version isn't able to install SGH T999V (windmobile, mobilicity) canadian variant roms because of some block T-mobile setup. Some people had done this, but didn't specificy how though.
I would like to know that please.
If you don't like bloat, then remove it. Don't flash another carrier's rom.

[Q] SGH-i747M rom on SGH-i747

Hey guys.. I'm new to this forum and to flashing ROMs and all that so I need your help..
I used the search option and didn't find a clear answer to this..
I have bought about a month ago an at&t SGS3 SGH-i747 and I am not very happy with the current OS (android 4.1.1 at&t stock ROM) and I want to upgrade it to 4.1.2. After searching google a bit i found out that there IS an official 4.1.2 android from at&t for my device and wherever I go they say to go to settings, about device, software update and update my phone from there but it says that there is no update.
I have searched for a ROM on sammobile and only found a 4.0.4 ROM for my phone.
However, I found out that there is a 4.1.2 ROM for SGS3 SGH-i747M, and some people say that their ROMs will work on my device and some say they won't.
Can someone tell me, if I install a Rogers (for example) i747M ROM on my device will it work without problem? I don't want to stay with the at&t ROM because it has too many limitations on them.
I prefer not to install custom ROMs because they are all a bit unstable..
Sorry if I have bad English, tried my best..
First off an (att) rom will work with a (rogers) phone. I'm using one right now.
Secondly, if you do manage to install a (rogers) rom on your s3 it will probably be missing apn settings and you'll have rogers apps.
Lastly, through my experience with custom roms, I have found that they are far more stable then stock, if you're looking for a good custom touchwiz rom. Look at hyperdrive

What you are describing on Sammobile are the stock firmwares that are flashed through a program called Odin. If you tried flashing a Rogers image, you could potentially brick your phone, or as the user above said, there would be a lot of issues since that is not the firmware for AT&T. Are you rooted? If you are, that is what is causing the upgrade issue, since you have to be 100% stock.

Thanks for your answer. Well, if you say that custom roms are more stable than stock, I won't argue. Just some friends told me otherwise.
I'll try to find a good rom that suits me.
Btw, I don't care if ill have Rogers apps or AT&T apps, they are both useless to me. I just don't want to brick my phone.

I didn't flash a Rogers rom because I couldn't find a clear answer that says that it will not brick my phone. I just seen some people ask about it and didn't get an answer either. I have tried to unroot and flash a stock rom from "samsung-updates.com", a 4.1.1. Its the same as the one that I already had. Still, no update available.

If you flash a ODIN package for rogers on an AT&T phone you may brick it due to bootloader and modem
if you flash a custom zip based on an AT&T rom from XDA you won't brick since they don't contain bootloader or a modem
hope this helps

How to Update Android on Unlocked AT&T S3 I747 for MetroPCS/TMobile

Hey guys so I decide to get the SGH-147 AT&T S3 off of ebay for MetroPCS which enabled me to get a 2 year squaretrade warranty. After looking back at it now, I feel it might have been a bad idea since Metro has a MIR 349.99 deal for their S3 version which would mean easier android update since it would be on Metro servers if I'm not mistaken. Anyway I can't return the ebay phone now unless there is some software or hardware problems within 30 days
So my problem
I am stuck on 4.1.1 on Kies and when I check for update, because the phone is based on AT&T servers, it won't work since I'm on Metro. I wanted to see if there is anyway for me to update my phone to 4.3 which is the current version. Although, I've heard some people have 4.3 problems?
If that's not advisable, could y'all tell me how I could atleast get to Android 4.1.2? Also is there a 4.4 update in the works?
I just got the phone today and would like to be running on something better than 4.1.1
should I flash the AT&T phone to a MetroPCS ROM lol, if any of those are actually available, or if I were to flash, should I flash it to Tmobile?
First off, if its I747, you MUST flash only those Roms. No others. Now, that's indeed a nice phone with LTE Antenna.
You really heard correct. The 4.3 upgrade from the carrier (ATT for you) /Samsung has a lot of issues. I wouldn't do it for any reason. Particularly on T-Mo network, you will have severe signal issues as reported by others. In addition, it now flashes an EFuse onto your phone along with locked bootloader and other scary stuff.I really would not do it.
Lastly, XDA is organized by devices. So even though you are a T-Mo/Metro PCS customer, you will have to post on AT&T SGS3 forum over there.
Speaking of Rom update, Please visit Root66 Thread for this device. You will find Rooted version of your Current Rom. Dunno why but he does not have 4.2.x for you. Please do your research someone else must have posted it.
Now speaking to 4.3, yes there is a way to get 4.3 on your phone without the issues I mentioned above. But first you will have to flash a Custom recovery such as CWM or TWRP with the help of ODIN on your phone. Again do your research well. Once those are in place, take a look at this thread. It will provide 4.3 experience without ANY concerns or issues. Read it carefully and then read some more. Good Luck.

THANK YOU! Looks like I got a lot of phone work to do over the weekend. SO do you think it was good/should I stick with this AT&T S3 or should I try to sell it for a discount and buy a Metro PCS S3? The ebay buyer won't take my phone back unless there is a hardware or software problem inherent to phone...unless I fake one ?
If it was me, I'd keep the phone. Metro's S3 does not have LTE Antenna. You'd have been stuck at lower speeds.

Metro's s3 does have lte
As for the OP you can flash at&t or T-Mobile ROMs it really doesn't matter because they are backwards compatible (I have done it) and you can flash 4.3 ROMs if you don't want to take the official 4.3 update which you can easily do with Odin without the need for kies or ota.. Now, I suggest the first thing you do is flash a custom recovery and then experiment with 4.3 ROMs, if you keep having problems flash 4.1.2 roms.. There are some things you need to do though to get 4.3 up and running so I suggest you read up on it first. Good luck my friend!

It was my impression he wanted Stock Touchwiz Roms not AOSP.
Thanks for letting me know Metro has T999L

[Q] Your Opinion 4.3 or 4.4.2?

I bought a Samsung Galaxy S3 on a buy sell group (well 2 of them, one was broken screen and one someone mangled the motherboard) I fixed up one to be good as new. It had 4.3 on it. Baseband: I747MVLUEMK5
I've rooted it, ( I know I can't downgrade it) I unlocked the sim via unlock code.
I'm Wondering if I should update it via Kies? (NF2 is available)
I use the samsung Gear 2 Neo on this phone, but I also have a Oneplus one for my main phone.
What's your Opinion of the NF2 Rom? Should I stick with 4.3 or upgrade? I'm not looking to try another mod rom, I've got a nice CM11 on my OPO.
Thanks

if youre talking about NF2 bootloader/modem (& not ROM) , i upgraded firmware from mj2 to NE4 and didnt notice any improvement. just my ยข.02.
"all i can really do , is stay out of my own way and let the will of heaven be done"
I decided to put kies on today and it prompted for an update. I assumed it was for 4.4.2 as most other people I noticed who had a I747m had 4.4.2, but this phone had not.
Is your phone an i747 or i747m? These phones use different bootloaders that should not be cross-flashed.
its a I747m, Kies is what told me there's an update.
Since you have the i747m, do not use any modems or bootloaders for the i747 as flashing those on your phone could brick it.
I suggest running the update until you are as up-to-date as possible. Then flash Philz Touch recovery, flash supersu to disable know and obtain root, then decide if you want to run a custom ROM or stick with rooted, de-knoxed TouchWiz.

[Q] Question about upgrading to KitKat or even Lollipop

So my sister's phone has been crap the last few months so I wanted to correct that. Turned out there might be a virus jammed in but I couldn't pinpoint it on an app or file (she has way too many things). So I just ended up factory resetting it and eventually decided to put KitKat or maybe even Lollipop on it. Getting KitKat on there isn't too much of a hassle. The only problem is that not finding a proper CWM recovery file. It still thinks the phone doesn't have a KitKat compatible recovery on it. Anyways Lollipop is my real question.
So I inadvertantly tried to install an International version of the Galaxy S2 Lollipop ROM which resulted in a soft bricking. After my mini heart attack I scoured everywhere for a ROM that was compatible with this version of the S2 and I got nada. Why didn't the International version work when it seems like they are practically the same? And if it needs to be I9100 then is there a way to change this phone to that? And finally why is there no word of a potential ROM for SPH-D710?
(Sorry if this was a lot, I'm legitimately curious and frustrated.)
The I9100 is GSM and the D710 is CDMA.
The dev for CM11 on this phone is working on getting CM12 working, but he doesn't like to talk about release dates. Just keep an eye out on the Original Development section.
f they could get a version of lollipop for the S2 international version... That can you not do one for the D710?
That not supposed that they should be very similar or equal?
Would that you can't?
