I am not a total noob and have done alot of research lately about my problem but have not found a concrete answer. It looks like there are alot of knowledgable people here. My problem is I was trying to get my friends T999 T-Moble phone to KK (CM11) It was already on Official 4.3 so I just rooted it, put TWRP on it, then flashed CM11. Now it looks like I have no signal at all but I don't know if that is caused by not having a Sim inserted.
Did I bork the Modem? If so, What can I do to get it back to stock. Dont care about the warranty counter. Currently I have the stock 4.3 image:
T999UVUENC2_T999TMBENC2_TMB
I have Odin 3.07
I am worried about flashing back down to Official 4.3 since I read about other downgrade issue. I had also made a backup in TWRP of the Stock Rooted rom. I am going to try and restore that to see if that helps or not.
If anyone knowledgeable can help me get it back to stock or at least return signal, I would gladly donate $15 for their time and efforts. In my line of work time is money and there isn't any free IT support. Thanks Guys!
Kind Regards,
Zachariah
Please disregard, I was able to fix it with the Backup I had made of the original firmware. Sorry for any confusion.
Moderators, please close this thread.
Thanks!

Hello,
About a month ago I rooted and installed a custom JB ROM (Kangdroid I believe?) onto my AT&T Galaxy SIII with the custom recovery mod. Now that the official release of JB has come out from AT&T I want to return my phone to it's original factory state with no custom anything, and then update to the official JB release. I don't want to use a custom un-bloated ROM. Call me crazy but I really didn't want to root/mess with the phone in the first place but I really, really, really wanted Jelly Bean. I already have backed up my contacts since that is the only thing I really need to save from my phone at the moment. I can download all of my apps again, etc. I tried searching the forums but couldn't come up with a very clear answer on how to do this. I found it hard to figure out exactly what I needed to do, and since I did this so long ago, I pretty much forgot how to do all of the little things that made my first attempt at flashing/rooting successful. I guess my question is this: What software do I need and what are some links (if any) on this site to help me return the phone to it's original out-of-the box state so that I can update my OS with the Samsung Kies software. Thanks a lot for your help and I hope to hear from some of you soon. Sorry for noobing it up in here.

The same way you rooted it with odin .. download the stock rom from here http://forum.xda-developers.com/showthread.php?t=1968625
push it on with odin and that should revert your phone back to stock ..
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

Definitely more info needed.
What ROM is on your device?
What bootloader did you install?
What modem/baseband/radio is on your device?
What method did you use to try to install the bootloader?
Is your phone still showing the correct IMEI in settings or 0 ? (Compare between that shown in settings and under the battery.)
It may be as simple as updating your modem, but I/we can't tell yet.

I'm new at this, in fact I have flashed by old Captivate several times but yet to flash my SGS3. Anyhow, I have spent many hours reading. Before doing anything I suggest, read, and read some more.
Don't flash back to 4.1.1 or 4.1.2 at this point. They will install an older bootloader than is currently on your phone. From what I have read, you narrowly escaped bricking your phone. You might want to read some of the threads regarding the 4.3 stock ROM and unbricking before making any changes in restoring your device.
You can probably fix this by flashing the modem that goes with the 4.3 series ROMs. It would also be the MJB flavor, although the MJ2 would probably work. Several of the 4.3 TouchWiz ROMs in the development forum have download links for the MJB modem. I would guess you were probably going to install one of them. I would recommend flashing the modem to see if that solves your issues before going ahead with the ROM flash.

The reason I didn't put a link in the previous posts was to get you to read about what you were doing as you searched for the modem. I am offering advice on things I have yet to experience on this device and only speaking second hand. My advice is only based on what I have read not on anything I have had to correct myself.
In truth I think you just stopped too soon in the process of what you were doing earlier. You said you installed the 4.3 bootloader in preparation to installing a 4.3 or later ROM that required the up to date bootloader. You didn't mention installing the current modem/baseband. You didn't mention trying to flash whatever ROM you had been considering.
You may be able to correct your device simply by installing the 4.3 modem. HERE is the modem thread, it is in the General Forum for our device. Make sure you pick the correct one. I don't know if your device will work well on the MJB bootloader and modem with a 4.1.1 ROM, from something I seem to recall reading I suspect it will.
Take this in steps. Install the correct modem, the one that matches your bootloader. See if that corrects you sim, data, and IMEI problems. If it does correct the issues, the next step is to decide if you want to stay on the 4.1.1 ROM or change to whatever ROM you had been considering. If you decide to change, make backups first. If it doesn't fix the problem while on 4.1.1 you may want to flash the version of the official 4.3 ROM enewman17 has provided on the development thread.
Take it one step at a time. Read about what you are about to do until you understand it well, all before doing anything. Make backups sequentially as you make each corrective step.
HTH.

thanks man for telling me what was wrong your an amazing human being and i love you (no homo) and thanks again a million thanks bro.
Did that modem fix some of the problems?
If your on 4.1.1 shouldn't you flash the DKL3 version or can't you just flash thru Odin the DLK3 stock ROM thru Odin Amd start all over again
I've been on 4.3 with that bootloader Amd have flashed back to 4.1 back to the baseband version DLK3 firmware. I would think being on 4.1 you should be able to reflash using Odin to fix the issue or flash the modem for 4.1 .
Can any of you fine chaps perhaps get the latest stock firmware of the SPH-L520 if at all possible? I've gotten myself into a mighty fine rut, and I won't be able to dig myself back out without the firmware. Unfortunately the latest stock image I have is several months old, and Knox prevents me from actually loading it into my ROM. Thanks in advance, and hopefully one of you guys can help me
Never mind, was able to flash a 4.4.2 ROM
Hello,
I'm a noob but usually try to fix this kind of issues on my own, looking at the boards, following tutorials, learning, but this time I think I'm not able to find a solution on my own so I'm asking for advice here.
Some time ago I installed cyanogenmod 10.1 on my Note 2 LTE and was happy with it for some month, than last week I tried to upgrade to cm12.1 It worked but there where some issues and bugs, mainly I wasn't able to swap internal/external sd cards.
So I decided to go back to latest available stock rom 4.4.2 from sammobile.
Here is where the problem starts. The stock 4.4.2 resulter in a bootloop, tried cache/dalvik/factory reset, flash again, whipe again.. nothing.
The phone is not able to get past the white label "Samsung Note 2 gt-n7105" screen. It goes black than the white label again and again.
It doesn't even get to the Samsung animated logo.
Ok bottloop, no problem, try to flash again something else.
I tried different Custom roms, different kernels, different flashing methods. I can flash anything with no problem but every time a get a bootloop.
During the various attempts knox fired, but I don't care. I don't know if this could be the cause.
Actually the only firmware that works is the original oldest STOCK 4.1.2, every other stock firmware past that or any custom rom is bootlooping the same way. To fix I only can reinstall stock 4.1.2 with odin.
I really need any advice or hint.
At the moment my goal is to get at least to stock 4.3 but I cant.........
Thanks!
When you first bought your phone, did it come with Knox?

nope it doesn't existed before, but now I can see it when I boot in download mode "knox warranty void:1"
Try to get the latest firmware available via kies ,that worked for me
http://forum.xda-developers.com/showthread.php?t=2088809/[URL]
From what you've described, I think the Stock ROM 4.4.2 from Sammobile contained a bootloader update. So when you flashed this ROM, it updated your bootloader from the non-Knox version to the Knox version.
I am very unfamiliar with the technical details of Knox, but I think the new Knox bootloader is causing your bootloop problem.
However, I don't know why 4.1.2 works when everything else doesn't work!
Can you check the Stock ROM 4.4.2, and see whether it really contains a bootloader update?

Since a boot.img is present, it means that it would flash your boot partition. So now we know for sure that when you attempted to flash the Stock ROM 4.4.2, your bootloader was changed to the Knox version.
So the lesson here is: before you flash anything via ODIN, always check to see if there is a bootloader update. Usually you don't want to be changing the bootloader on your phone.
***
So now there are 2 possible ways to reach your goal:
1) Keep your new bootloader and see whether you can get Stock 4.3 or Stock 4.4.2 running on your phone
2) Try to restore your old bootloader
As I said earlier, I'm not familiar with the technical details of Knox, so I'm not sure how to get Stock 4.3 or Stock 4.4.2 running on your phone when your Knox indicator is already 0x1. You need someone else to help you.
And you can only restore your old bootloader if you happen to have made a copy of your boot partition before you flashed the Stock ROM 4.4.2. Even if you did have a copy of your original boot partition, I'm not confident with helping you to restore your old bootloader. You need someone else to help you in this case too.
Conclusion: I don't think I can help you to solve your problem I'm sorry. Hopefully someone else who is more of a pro than me will come along to help you out.
Good luck!
