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.

I was wondering how would I do this. I wanted to flash JediMaster X but im rooted on 4.1.2 Jedi X. How would i go about updating to stock 4.3 without installing knox so i can get the working bootloader then update to Jedi Master X ?
I would prefer if the stock ROM was rooted already and knox removed. Anyway have any links.
Has anyone done this process ?

Hi, even though you are on stock 4.1.2, remember: you have root privileges now. You can flash any ROM designed/built for your particular variant of the Note 2. That simply means stick with flashing ROM that match your device's model number.
Next, I flashed JediMasterX this morning. It is built from stock firmware Android 4.3 for the Note2 so you can flash this ROM, if there's a build for your variant. You don't need to flash the actual firmware to upgrade to 4.3 ROM. All builds in the forum come from source code, which means there is a base design for each kind of phone, but Android is Android and it follows certain predetermined rules.
One thing you need to do is read the OP to whichever ROM it is you are thinking about flashing. The ROM chef is going to place some very important information on the first page where they present their ROM. It is much advised that you follow those guidelines down to the letter. For instance, you want to flash JediMasterX, right? Did you know that the OP mentions that if you haven't already updated to 4.3, (BTW...there are links in the forums for each carrier to download the stock firmware and they're already root and you don't have Knox to worry about!) that you should flash a particular kernel after flashing the ROM. You'll even find a link to the stock 4.3 modem, which is necessary for providing a data connection. That is less necessary than flashing the kernel and the OP explains why.
I hope this has helped. Make sure you have your custom recovery set-up and that you already have a Nandroid backup of your root stock firmware or another ROM you have recently flashed. Always keep a backup, more than one is even better!
Happy Flashing!

Yes I want to flash JediMaster X but I heard that if i don't have the stock bootloader WiFi will be dropping in and out. Support for devil kernel in V2 is being dropped or something (so i wanted a solution in which i don't have to flash devil kernel) so I need to have the stock bootloader to have stable connection. Yeah I was just looking for the simplest process to get everything working on JediMasterX 4.3

I totally understand you. And that's where that kernel I mentioned comes in. It's called the dual-boot or Devil's kernel by @DerTeufel You need to either flash that kernel after flashing the ROM via the Aroma installer. Reboot back into recovery and flash the kernel OR flash the bootloader patch provided by another senior contributor in the forum. That link is somewhere in the OP and you have this option. Download and flash the stock root 4.3 firmware -- it already is Knox free -- for your device. Then flash your downloaded JediMasterX ROM and you won't need to worry about flashing the kernel.

I forgot to mention one other thing. I know that JediMasterX was shared with us earlier in December. One thing of interest, and this is solely for your information...don't go trying it until you're more comfortable with flashing and more importantly recovery! The N7105 is compatible with the T889 and that allows us to flash ROM built for our respective variants. The Devil's kernel was built for the N7105 originally. And I just downloaded a pretty updated -- as of this month -- version of the kernel yesterday. I did read in @DerTeufel's OP for the Devil's kernel that he wouldn't be supporting any requests for changes to the kernel. But the kernel is solid. Has been for quite some time!
Sorry it's taken me long to reply. Wouldn't you know my phones are both drained and I hadn't turned on my computer yet. Anyway, important thing is to read, read, read. I know you might get bored clicking through pages, but it's really cool when you find updates to certain ROM you like buried in those pages instead of posted on the main page. Or you find tips to a having a better experience on the ROM you happen to be on by using a mod listed in a forum. And you can learn a whole lot from everyone in these forums, but reading through the forums will teach you things about root, what you can and cannot do, that no single person can.
Hope this helped! Have fun flashing!

Yea, you're going to download and flash through desktop Odin the stock root 4.3 firmware. You download the zip, unzip and place the .md5 file in PDA of Odin. You'll then need to flash a recovery image through Odin as well so your recovery partition will be ready to flash into recovery and then backup the stock root firmware. Keep it in case you want to go back. And always do a complete wipe in recovery for a clean install of any ROM you flash.
Computer is super slow today. ARgH! lol

I know what you mean and I'm using the official ROM now without Knox
Step 1: Root your phone
Step 2: Install Titanium Backup pro (u can download the APK from apkmania or any other site)
Step 3: Find the apps in the screenshot from Chrome to Mobile life
Step 4: back up each one of them (in case if u need Knox later)
Step 5: uninstall
Step 6: have fun, your phone is Knox free

New galaxy user, here its a s3 for ATT 4.4.2 i747CUCFNE4. I have rooted using the Cf Auto-Root method.
Along the lines of trying to flash a new task manager apk, (for I had to factory reset my phone because the original task manager was missing) I came across a thread that had s5 apps (settings apk) and tried flashing this apk(don't laugh I know.) Then I couldn't get my phone to boot through the standard setup wizard. So I tried booting into recovery and factory resetting my phone clearing cache, dalvik, and partition.
My biggest problem arose when I chose to format system from ghe recovery.
I know all this can be fixed with odin but I can't find a 4.4.2 os link, I have read I can't simply downgrade my os. A link to a 4.4.2 stock rom thread would be greatly appreciated. I also have the Ktoonsez kernel installed if that makes any difference.
AT&T never released a full 4.4.2 ROM. AT&T released 4.3 and 4.4.2 via OTA updates only.
Since you are on the NE4 bootloader, do not flash anything that will attempt to downgrade the bootloader or the modem. A mismatched modem/bootloader combination may cause other problems.
Have a look here: http://forum.xda-developers.com/showthread.php?t=2789917
Ok I just reviewed your link in your response but just to be clear I'm starting where it says step 3: stock deodex and root and finishing the walkthrough from there?
And also will this reset me to my factory kernel?? Either or it doesnt matter to me I'm still trying to find one that I find suitable.
And I appreciate the speedy response you've been a huge help.
If you just want to get your phone up and running, I would flash Philz and then CM11. Confirm the bootloader and modem then decide if a stock ROM would be best.
I am always paranoid when it comes to flashing bootloaders on the s3 so I prefer to know exactly whan my phone is running.
I have never used the thread I linked because I no longer have an s3 i747m. Infact, I haven't had my s3 for several months.
Ok and my last question is you can flash Philz and CWM 11 through odin?
Nevermind I see it now greatly appreciated
I hope it all goes well. With CM11, you will also need to flash Gapps via CWM as CM11 does not include certain apps such as the Play store.
Now odin wont recoginize or open any of my rom files. Li see the rom im trying to flash by name but when i click open it only opens the next folder instead of initiating the flash. I really just need someone who has a 4.4.2 stock rom in md5 format.(edited or not.)
As a last effort if i get no answer im going to try to downgrade to another os and reupdate to 4.4.2 right after. Ive been searching for days now all i see are guides from how to upgrade to a different os . If it does include 4.4.2 they only posted the update and not the entire rom.
And when i do find someone posting a full rom for 4.4.2 its either not for 747i or its not a md5 file so someone plz help me.

DO NOT downgrade to a bootloader older than your NE4 -- doing so will cause a hard brick.
You did mean i747 instead of 747i, didn't you?
Odin is designed to not flash any stock rom that would install a bootloader than the one on your phone. this is to save you from hard bricking your phone. Since you are on 4.4.2, any stock rom in a .tar.md5 format has an older bootloader than your NE4. As far as I know, the only stock NE4 rom on the forums is in a .zip format for flashing from recovery, it was posted by enewman17. (The thread audit13 linked.) If you tried to flash an older bootloader and baseband package through recovery you will probably hardbrick the phone.
Otherwise, there are roms based on TW in the forums: S3Rx, TMS3KK, Likewise, and others. Some use the stock kernel, others give you an option from their Aroma install. The iBubbler's kernel in a couple of these roms is reported to be excellent.
I'm guessing you pulled your S5 apk from either the S3Rx or Likewise thread.
I appreciate everyones feedback and guideance. Yeah I meant i747. It gets pretty easy to misread something when all you've been doing was researching roms and guides. And now its back to researching and finding one of the roms you mentioned. Much appreciated everyone I hope u all have a blessed day..
i know this a zip , but maybe could find help in the thread.

"all I can really do, is stay out of my own way and let the will of heaven be done"
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.

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.
http://www.sammobile.com/firmwares/database/SGH-I747M/
Not sure if it is useful...
Any way to install the custom room??
Cheers

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.

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?

I see audit13 is helping you in the other thread, therefore I will not confuse things and also reply here.

But the newest firmware is bad because it has evil bootloader.

Check my long post over there.
I'm currently running CM12.1 on my phone. I love it, but I want to return to stock and give my phone an "out of the box" feel, and return it to the way Samsung made it to be.
I follow the typical instructions found here, but I always get an error (no screenshot available. Sorry!). I'm running Windows 10 and I have the proper drivers installed. Is there something I'm missing?
If the phone is running a 4.3 or newer bootloader, you cannot flash back to stock using a stock rom from sammobile.
Before flashing anything, I recommend verifying the bootloader and modem before flashing anything else. An improper bootloader and modem combination could brick the phone.

Alright. Thanks. A bit disappointed, but thanks anyway. Besides, CyanogenMod isn't bad.
I was just running CM 12.1 / 13 and I was able to revert back to Roger's Stock ROM Android 4.4.2
Try Odin3 and installing the stock rom. But you should always verify the bootloader.

If the OP is running the i747, it is the the AT&T version of the s3. AT&T never released a full firmware release for use in Odin after 4.1.1. AT&T only released OTA updates that upgraded the phones from 4.1.1 to 4.4.2. In order to flash a stock AT&T 4.4.2 ROM, it needs to be done from TWRP.
