Background: I attempted to update from SlimKat 7.0 stable to 9.0 stable and discovered my apn's were missing and when I try to add them manually it fails to save. I have also found others with this same issue but none have an easy fix. I'm on UCDLK3 firmware, after restoring to previous state using nandroid backup apn's are present. If I try to flash any ROM (even other than Slim) my apn's are missing, even a dirty flash of 7.0 over 7.0. I know I can fix this by flashing stock UCDLK3 and root/twrp/flash slim 9 and everything will likely work fine. I plan to do just that but want to make sure I'm doing things as smart and clean as possible. There is a lot of info out there and I'm finding it hard to sift through old stuff and find the current state of things.
Question: Is there an actual advantage if I upgrade the firmware from UCDLK3 to UCUEMJB while still planning to use SlimKat 9 Stable with BMS kernel and TWRP recovery? Are there any disadvantages? Either way what is the shortest path to get back to stock (either LK3 or MJB) and flash SlimKat?
Thanks
Your APN may not be sticking because your modem and bootloader may be too outdated.
Some of the latest CM11 and AOSP ROMs require a KK bootloader and modem.
And then there are some roms that require at least a 4.3 bootloader and modem, either the MJ2 (leaked) or MJB (official) bootlaoder/modem combos. I have seen mention of these working in some OPs and in the body of other threads. In some of the later TW ROMs you may have to use a custom kernel like kt747 or iBuddler's. I don't know if any kernel other than the stock in SlimKat and AOSP ROMs would be needed with the MJ2/MJB firmware and modem.
I don't know of any advantages other than some of the ROMs require firmware newer than DLK3 to properly boot, receive data, or have a working wifi. As far as disadvantages, KNOX was introduced with the MJB firmware and stock ROMs, once going to MJB or newer firmware you can not make firmware downgrades without a very real risk of hardbricking your phone. Also you will need to insure your baseband and modem versions match. If they do not you risk hardbricking of another variety.
I had not yet realized that the newer AOSP and CM11 required you to go all of the way to NE4, thank Audit.
Just wanted to close the loop on this thread and say thanks for the assistance!
I now have my phone working properly on SlimKat 9; it really was just the firmware not being compatible with newer ROMs as many have suggested. Here is the sequence I followed to do it but really it probably only needed a twrp flash of the mjb firmware and the ROM install:
1. Used odin to restore to stock LK3 (only because I had messed with things so much and wanted a clean slate)
2. Used odin to install TWRP 2.7.1.0 recovery
3. Rooted with SuperSU 2.40 using TWRP
4. Flashed combined MJB modem & bootloader using TWRP
5. Flashed SlimKat 9 using TWRP
6. Flashed Slim GApps using TWRP
7. Rooted with SuperSU 2.40 using TWRP (Lost root after flashing ROM)
thanks for posting fix. am sure it will help others. audit13 and dawgdoc , thank you for continued help with the awesome Slll. :good:

When you restored to LK3, what Firmware version were you coming from? I'm looking to go to LK3 from the NJ1. However there seems to be cautionary red flags all over the place due to bootloader changes that were made in 4.3.
The OP was already on LK3 with a custom ROM.
Since you are on NJ1, you cannot downgrade the bootloader.
I'm using SlimKat 4.4.4, yet my phone's baseband version is 4.1.1 (I747UCDLK3). I'm looking to upgrade my baseband version to 4.4.2 due to some issues.
Can I upgrade straight from 4.1.1 to 4.4.2?
Or do I need to upgrade to 4.1.2 -> 4.3 -> 4.4.2? If this is the case, I have one concern. There are many footnotes saying if you downgrade from 4.4.2 to a lower version, you will brick your phone. These footnotes don't specifically say whether they're talking about OS version or baseband version. Is it safe for me to upgrade to 4.1.2 -> 4.3 -> 4.4.2 with a 4.4.2 ROM? Is it safe for me to flash a 4.1.1 stock ROM?
Any help appreciated. Thanks!

first if wanted , i would get the free unlock sim code (am pretty sure is available on 4.1.1).
all i have ever read says to do the incremental updates (safest).; which i believe you can do OTA ; or flash thru recovery.
yes , you will most surely brick your phone if you try to downgrade bootloader from 4.4.2.
AND you want to keep bootloader and baseband at the same version. upgrade one then upgrade the other.
if your already on 4.1.1 , then yes flash away the stock 4.1.1 rom ; if youre talking about after you upgrade to 4.4.2 then the 4.1.1 may not flash unless you edit the updater script (think thats what its called , been awhile).
good luck !

This is an I747, right? I think the I747M had LK3 firmware too. If you happen to be on an I747M don't flash any of the I747 specific stuff below, or you'll probably brick your phone.
Since you're still on the old firmware it might be a good idea to carrier unlock your phone if you haven't already done it. You'll lose that ability if you update.
To update to 4.4.2 firmware you can go two ways. You can Odin back to unrooted stock and you should start receiving OTA updates. They will be incremental and they'll come about 24 hours apart, or you can set your system time ahead a day to cheat that. Eventually you'll get up to the 4.4.2 firmware. NE4 is 4.4.2, but NJ1 is the most recent. This is probably the safest way, but it will be somewhat slower. Those OTA's are full firmware packages so they're big downloads.
Or you can flash bootloader/modem only upgrades in custom recovery. Enewman17 has posted everything you need to get an I747 up to date to XDA. I flashed all these while running the Slimkat stable 9 ROM to get my I747 from LK3 up to NJ1. This has to be done incrementally and you have to boot successfully into your ROM in between each firmware flash. You can't jump from the 4.1.1 bootloader to the 4.4.2 bootloader. First flash the MJB firmware update linked to this thread then reboot into your ROM. Next flash the NE4 firmware zip also linked to that thread and then reboot into your ROM. You're on 4.4.2 firmware at this point, but if you want to be on the newest bootloader and modem then flash the NJ1 zip attached to this thread. If you go this route be sure you read enewman's posts very carefully and understand exactly what you're doing because fiddling with the bootloader and modem is the #1 way to hard brick this phone.
For the most part you can flash any ROM you want no matter what firmware you're on as long as it is intended for I747. You might find that your wifi won't work or your modem doesn't work or maybe it just bootloops if you get on a ROM that wasn't intended for the bootloader/modem currently on your phone, but you can still boot up into recovery and restore a backup or flash another ROM and get out of that. What you have to be very, very careful with is the bootloaders since Knox was introduced, that's MJB, NE4, and NJ1. Those bootloaders cannot ever be downgraded; don't try it. You'll hard brick and it is pretty hard to recover from. Its also for the best to keep your bootloader and modem matched on this newer firmware; the OTA method or the zips linked to the threads above will do that. Custom ROMs that are AOSP/CM based won't ever mess with your bootloader and modem. They're just a system image and a kernel. What you have to be really careful with is Odin, those are usually full firmware packages. AT&T hasn't allowed a stock image beyond 4.1.1 to be released for the I747, so once you're on the newer bootloaders there is no more option to Odin back to stock.
Good luck.
Hello,
Trying to install the custom ROM cyanogen mod 11.
http://forum.xda-developers.com/showthread.php?t=2682905
First time I ever attempt to flash a custom rom.
In the guide it asks to DL Bootloader & Modem. My baseband is:
I747MVLUFOB3
I can't find any baseband corresponding to this one.
Here I found a firmware that correspond to my base band.

Not sure if it is useful...
Any way to install the custom room??

Which variant of the galaxy s3 do you have? You should be able to flash any ROM compatible with your phone using TWRP or Phil touch recovery.
I have the i747m (rogers canada). I have TWRP 2.8.7.0 & rooted with Kingo root. Somehow it was the only way to root it. Tried Towel root & odin but both were doing nothing.
TWRP was installed a long time ago. I recently made an update on kies (what a mistake sign...). I was on 4.4.2 before and after the firmware update on kies.
I got a spare S3 motherboard (with cpu etc.) I might try on that one first but I need to disassemble & assemble everything... not very tempting.
I usually just use odin and http://www.sammobile.com/firmwares/ to start fresh and root again when I want to upgrade bootloader and modems.
As you saw at sammobile, OB3 is the latest official release for the i747. You do not need to do anything to your baseband (modem) to run CM11. You may want to verify that your bootloader (firmware) matches the modem. This can be done from within TWRP. Go to the advanced menu and in the terminal enter
Code:
getprop ro.bootloader
You should get a return ending in OB3.
I suspect the CM 11 updater-script has not been updated to account for the just released OB3 firmware. If that is the case, you could always edit the script in the roms zip file.
@dawgdoc
When I entered the command, it returned me:
I747MVLUFOB3
Secondly, I have not tried to install CM11 (or the newer version CM12?). I do not know if it works. I just want to make sure I can flash and not brick my phone.
My phone is not the d2att (i747), it is d2can (i747m). I believe these two are very similar but enough different to cause problem.
So, can I install CM11 or 12?
You are talking about changing a zip file... The newb I am know how to do that, but what exactly - that he doesn't know. So I would rather not mess with that. I guess TWRP checks if the firmware of the bootloader / modem matches to those from a compatible list and simply updating that list would allow me to install the build?
I was thinking about this ROM:
http://forum.xda-developers.com/galaxy-s3-att/development/unofficial-cyanogenmod-12-t2968854
Don't know the exact difference with the CM12 but it says d2can.
However, the BaNkS GAPPS - GAPPS link does not work... I don't know what that is.

The unofficial CM12 -5.1.1 by @matrixzone is good for the i747M, aka d2can. If you have any doubts, ask on that thread if it is updated to run on OB3? Matrixzone is active on the forums and should respond to your question. Also I just checked the updater-script for the latest CM11 official nightly and it is set up to run on the i747M.
So, either should run with no problems for you.
What is the bootloader and modem version needed and how do I get them without getting a locked bootloader? I'm on i747M with 4.1.1 Stock rom with DLK4 modem and bootloader. There are newer bootloaders and modems that can be flashed through recovery but some people have been getting bricks when messing with bootloader.
THey say to use Official firmwares to have it update the bootloaders but which one is the proper firmware version to get the proper bootloader and modem version to allow DATA 4g LTE after flashing CM12.1 Lollipop rom?

Check my long post over there.
Hey all. I am fairly inexperienced when it comes to rooting, though I have done a few succesfully in the past. I currently have the newest version of TWRP installed on my Samsung I747M. The I747M I have is not from one of the major carriers, but as far as I am aware, the phone is factory network unlocked. Carrier is GCI, in Alaska.
I currently have a 4.4.2 Touchwiz Rom installed and started having problems after I attempted to flash the ROM Dandroid, which is 4.3 (http://forum.xda-developers.com/showthread.php?t=2121506). I had created a backup using TWRP before flashing the ROM and reverted back once I noticed the problem.
The main issue I am experiencing at this time is the Baseband Version, IMEI, and other information related to the modem is showing "Unknown" and features such as wifi will not toggle on.
I had also attempted to flash the most current version of the modem that I was able to find thru Odin. Odin showed the flash as successful. The version I flashed to the phone was I747MUMUEND3: modem_CWM_I747MUMUEND3.zip - 18.80 MB - April 3rd, 2014 (http://forum.xda-developers.com/showthread.php?t=1831898)
At this point, I can still get into recovery, download modem and I am able to boot up the phone and access most all functions. The next step I was going to try was going to be to flash back to stock firmware from sammobile's website (Was using to use the Roger's version of 4.4.2), though I don't want to cause more issues than I can handle or resolve thru software.
Any advice on how to proceed would be greatly appreciated or even just how to get the modem/wifi features functional again would be helpful. I'm just as happy staying on my current ROM at this point if I can get the phone fully functional again.
It's possible that the rom is not compatible with the kk modem and bootloader.
Flash cm12.1 to see if your imei comes back.

Forgot to mention, this is something I did try. I attempted to flash Cyanogen Mod 12.1 (Download: cm-12.1-20151017-NIGHTLY-d2att.zip (286.76 MB) ) and most recent nightly build & the most recent stable release (CM11) (Download: cm-11-20140210-SNAPSHOT-M3-d2att.zip (194.37 MB) ). When flashing these, I transferred the downloaded ZIP file to the internal storage of the phone in the root directory and attempted to run an install from TWRP. Both installs failed.
Since the phone is an i747m, I recommend flashing back to stock using Odin 3.07 and stock ROM file from here: http://www.sammobile.com/firmwares/database/SGH-I747M/
The i747m versions are interchangeable between Rogers, Telus, and Bell.
After flashing back to stock, install TWRP using Odin 3007 from here: https://dl.twrp.me/d2att/twrp-2.8.7.0-d2att.img.tar
Create a nandroid backup using TWRP and then try to flash a custom ROM again.

I'll give that a shot when I get home. Stock firmware was one of my next thoughts. I have it downloading at the measly 15 Kbps offered for free from sammobile so hopefully should be done by the time I get home & update this thread with any progress.
Another possibility is a custom kernel, if you are wishing to stay with TouchWiz and not wanting to upgrade your bootloader and modem past 4.3.
Some of the 4.4.2 TW roms will run on 4.3 bootloader and modems using one of ibuddler's kernels or ktoonsez's TW kernel. This was discussed most in the Likewise ROM thread and links to the various versions of ibuddler's kernel may be found there. It may have also been discussed in TMS3KK thread. The ktoonsez kernel can be found in its own thread.
But, you may really want to consider a newer ROM in order to change to something with the stagefright fixes. I think any of these may require the latest 4.4.2 bootloader and modem. (What say you @audit13?)

I'm not opposed to any of this. Mostly just trying to slim down this phone to the basics as much as I can and am quite open to any recommendations. Main thing I want to maximize is battery life & simplicity since this is for my wife and those are her major wants in a phone. I figure any kind of ROM that just covers the basics should cover my bases & would prefer one with a darker/black skin to maximize battery life w/ the OLED screen. I am in the process of flashing to the Roger's stock ROM as I type this w/ my fingers crossed.
Just to add, no over clocking or anything of that nature is desired. If I remember correctly I ended up putting the ktoonsez kernel on one of my handsets, either this Galaxy S3 or my Galaxy S5, though I can't recall which since it was so long ago.
Alright! So progress! Wifi, Baseband version, IMEI and all other missing information restored & now works w/ stock rom flash. In process of reflashing TWRP now.
Let us know what happens.
Still all good with TWRP installed. Have not flashed back on a custom ROM yet. After reviewing some of the above recommendations, I am kind of liking the looks & features of TMS3KK (http://forum.xda-developers.com/showthread.php?t=2725750) and feel it would suit my needs.
I factory reset, cleared cache, and cleared Dalvik thru TWRP & then made a back up. Prior to this, I confirmed everything was still working normally w/ phone fully loaded after TWRP was installed.
One of the things mentioned on the installation instructions for that ROM is the following:
---
Do not mix and match 4.3 firmware (bootloaders/modem) with the new 4.4.2 ones. You will hard brick and I warned you. This works the same as any 4.3 or ND8port ROM with 4.3 firmware and it can use the new 4.4.2 ones also.
Link to recovery flashable i747 and i747M 4.4.2 bootloader and modem packages: http://forum.xda-developers.com/gala...hable-t2856914
---
How would I go about confirming my current bootloader/modem versions to make sure they are both 4.4.2 before flashing this ROM? At the link provided, those files/links to the files were removed because they were causing some bricked devices per a note at the top of that thread. Here's a link to the thread I am referencing since the above link looks to be broken. (http://forum.xda-developers.com/gal...mware-ne4-ne6-nf2-recovery-flashable-t2856914)
If you flashed the latest stock rom, you are running the latest 4.4.2 bootoader and modem.
You can download and run the Samsung phone info app from the play store to confirm this.
You should be good to flash any d2lte or d2att rom.
I recommend not flashing any modem or bootoader from this point forward unless the bootoader and modem are newer than the currently installed botloader and modem. Also, the botloader and modem must be matched to each other.

Thank you so much for the help and information. I guess I never realized that the bootloader & modem were installed w/ the stock rom as I always have flashed those separately through Odin when needed. Definitely good information to have and not easy information to find. I have successfully got my custom ROM on there and am now fine-tuning it for the wife.

If you are still on the original bootloader and modem you should be able to revert to stock 4.1.1 by simply restoring the backup from your recovery. Before you attempt to do so verify that you are indeed on the 4.1.1 bootloader. This can be done with the Phone Info *Samsung* app by VndNguyen (?sp) from the playstore or by a couple of terminal emulator commands:
Code:
getprop ro.bootloader
getprop | grep version.baseband
If you do not already have terminal emulator installed, it may have come with the ROM, you can get it from the Playstore. It may also be a part of CWM recovery, it is part of TWRP I know for sure.
If it turns out you are on a newer bootloader and modem then go with a stock ROM that matches the bootloader and modem on the phone. To run a lollypop rom you will need to be on at least the NE4 bootloader and modem.
Thanks for a very helpful reply. I m going to follow your instructions. Will soon replay. Thanks again.

You are currently running the LK3 bootloader and modem. If I am not mistaken that's a pretty old one (original?). You will have to update to NE4 or newer firmware before you can flash any of the newer roms. They will not boot in the older ones.
Your firmware is actually the only one available for download so I recommend flashing it via Odin and factory resetting. Then update using the Software Update option in Settings > About Device.
You can download your LK3 firmware here: http://www.sammobile.com/firmwares/database/SGH-I747/
You may have to run Software update several times to fully update.
That is probably the safest and easiest course you can take.
After that, flash the latest custom recovery of your choice, then flash the rom you want.

BTW, after flashing the LK3 firmware, you might want to consider using the free Sim unlock method. (Should be pretty easy to find).
Once you update past 4.3 you can no longer use it. It will allow the device to be used on other carriers networks, which can be beneficial if you ever want to sell it or switch carriers.

What DocHoliday77 suggests is probably the safest method to get what you want. After each update the system will force you to wait 24 hours before you can make the next update. That would be three days to get to NE4, the first 4.4.2 release by AT&T, which you need to run lollipop ROMs. If you want to update to the current release (NJ2) that would be two additional days.
You can shortcut the required waiting period by manually advancing the system date after each update.
In addition to not allowing you to use the free unlock, once you take the 4.3 bootloader it prevents you from downgrading bootloaders. Newer bootloaders do the same, downgrading will be a thing of the past. (I never took the official 4.3 bootloader until the stagefright scare came along and I went from my older custom ROM to a new release.)

1:- Okay I fully understood what I have to do to flash lolly pop . But confused a little bit . If I have original boodloader than it should be easier to restore my stock 4.1.1 . Backup (still not clear) .
2:- I am out of USA. The device in unlocked. I am using ZONG sim on it. So the question is can I still update the device via OTA.
Thanks

When you say original bootloader I don't know which you have. My i747 came with 4.1.1 but before I could get it out of the clerk's hands they had taken the OTA to change it from DLK3/4.1.1 bootloader and stock rom to MG2/4.1.2 bootloader and stock rom. Even more confusing I have read reviews that state the SGS3 was originally released with android 4.0.4.
If your original bootloader was older than 4.3 (MJB) AND you have never upgraded to MJB or newer, then you can safely return to stock 4.1.1.
To get OTAs you need to be on the stock ROM, at least you do in the USA. I don't know if that holds true elsewhere.
I can confirm the S3 was originally shipped with 4.0.4! We were updated pretty quickly though.
As for the OTA'S, you do have to be full stock, not rooted. But you also have to be on AT&T network.
I don't know how far back the OTA'S are hosted around here, but enewman17 has several threads that provide the more recent ones. Hopefully someone will have the older ones. If I am not mistaken, you will have to update incrementally once you reach 4.3. (it's probably safe to jump straight to a 4.3 build if you can find the right firmware for it. But don't hold me to that as I am not 100% certain.
I'll look to see if I can find something you can use too.

Thanks men for quick response.
now I m fully confused. Don't know what to do. because I don't want to stuck on this battery enemy rom. (Aokp kitkat. Custom rom )
I am not clear about boootader version (PHONE INFO SAMSUNG APP SAYS ITS i747ucdlk3 ) but I know when got this thing. It was android 4.1.1 . Which I have back a backup. As per I am out of att network and I can't get OTA,s so I don't need to revert to 4.1.1 backup. I think I have to find out 4.3. For my device. So kindly please inform me if some one knows about . Iwill be very thankful to u people.
Again thanks

I got this while searching online. Please tell me if it is helpful for.me.
http://androidromupdate.com/att-samsung-galaxy-s3-sgh-i747-odin-stock-firmware/
Never been to that site, but it looks OK to me. Nice find in fact! All the usual firmware sites stopped getting the AT&T firmware a while back.
Anyway, just to clarify, LK3 is 4.1.1. UCDLK3 is just the build number.
If you want to get fully updated, I suggest Odin flashing the MJB (4.3) firmware. Then flash each of the OTA's until you are updated to where you want to be. (I would fully update, but that'll be up to you.) The OTA'S are intended to be flashed from stock recovery, but there is another option if you want to try it. Mobile Odin is an app by chainfire. It does require you to be rooted, but it will flash the OTA. Read his thread here on xda to learn more. It's one of my favorite apps tbh! Once you learn how to use it it makes flashing quite easy.
So my recommendation would be this:
Flash MJB with Odin.
Root using Towelroot (easiest root ever)
Install Mobile Odin and flash the OTA'S.
I hope that clears things up a bit!

Update:- I am stock 4.1.1 now . I restored the device from custom AOKP kit kat rom using the stock 4.1.1 backup which I have made via CWM recovery. The device is running perfectly.
*****tried to run OTA but it says ur. Device in up to date . Means I cant get any OTA up date . So the question is can I get any custom lollypop rom using this older bootloader. ? (LK3)

To be able to run a lollipop rom you will need to update bootloader and modem. Update them together, this is important once you reach the 4.4.2 level of bootloader and modem that you will need to run lollipop roms. Once you reach 4.4.2 you will brick your phone if the bootloader and modem versions are not the same.
Before starting to flash any of the files you need to get you up and running on lollipop, I strongly suggest you download all you need from start to finish. Store the files you will need in the upgrade process either on an external sdcard or on the root of your internal sdcard. I haven't used CWM Recovery on my SGS3 since shortly after rooting it, I have been using TWRP since then, and I don't recall all of the capabilities of CWM recovery. If the CWM version you have will not let you flash from an external sdcard you will need to store the files you will use on the root of the internal card to be able to flash them. It will be easier to do this before you start, unless you are comfortable with pushing files from a computer using adb.
BEFORE DOING ANYTHING I AM SUGGESTING read enough that you thoroughly understand what I am saying. After reading, ask questions for clarification. Be sure you have no doubts.
Decide if you intend to install a rom along with the bootloader and modem at each upgrade; or if you are going to install updating only bootloader and modem until you get them to them point that you can run a lollipop ROM. Since you said you can not do OTA updates, either way will work. Whichever you decide, you can not skip directly to the bootloader and modem you need for lollipop.
If you are installing bootloader and modems without the rom:
From the stock 4.1.1 rom and bootloader you can go straight to 4.3 bootloader and modem, skipping the 4.1.2 (MG2) version. I have personally done this with no ill consequences. After 4.3, install the first bootloader and modem version for 4.4.2, that is NE4. Lollipop will run with the NE4 bootloader. As DocHoliday stated, you can go on the the current bootloader and modem. After NE4 is NJ1. After NJ1 you come to the current bootloader and modem, which is NJ2
If you plan to install the full ROM at each step.
The page you linked to should work if all of the downloads are available. Go from 4.1.1 to 4.3 to 4.4.2 (NE4). If you want the newer versions (NJ1 or NJ2) do them in sequence, do not skip any that are mentioned. Read the instructions on your linked page carefully. If you want NJ1 and then NJ2 they can be found in threads by enewman17, as can NE4 and maybe 4.3. I didn't provide the links so that you will hopefully read the pages carefully after searching and before downloading. Be sure you understand what you are downloading to flash and how it should be used.

Flash MJB and NE4 from the site you linked to above. Then use enewman17's thread for the NJ1 and NJ2 updates. He also has NE4, in case you want to get all the OTA'S from him. (Downloads will be a lot faster) They've all been used many times. I'll try to post a direct link in a few...

I got this site having all ota, s . And is linked to the enewman17.
www.androidayos.com/samsung-galaxy-s3-stock-firmware-2/
Lol, I guess they thought they had to provide it somehow! It's a shame they didn't at least acknowledge enewman17 in their article there, but at least they direct linked to his thread.
Anyway, good luck! And if you have any other questions come up, let us know.
