[Q] Trouble to upgrade bootloader from MK5 to MJB to NE4

I've been serching for an answer for a while and can't seem to find a proper one that makes sure that I won't brick my phone. I've been flashing roms since 2011 and know pretty much the drill but lately I've been flashing at a couple months interval CM11 m builds and since I don't follow the threads like I used to, I feel like I'm missing out on how to do the right procedure.
So this is my phone:
Rogers i747 SG3
Cm11 4.4.4
Bootloader: I747MVLUEMK5
Baseband: I747MUMUEND3
I've installed these about a month and a half ago and since I've lost LTE networking but I didn't care to try to fix since I don't use it that much and left it like that.
This morning, I tried flashing MJB bootloader and modem zip in recovery but it gives me the classic error 7
Any Idea how to get out of this impasse? I've been searching all morning and can't find what I'm looking for...

I see you're in Montreal. Do you have the AT&T version of the s3; i.e. i747?
Your bootloader (MJB - 4.3 AT&T) and modem (ND3 - Telcel) appear to be mismatched. Maybe this is causing the loss of LTE connections.
What recovery are you using? Is it up to date?

I use Clockworkmod recovery 6.0.4.7 The latest version and Its an at&t i747 phone but with Rogers(same thing).
Is there other basebands or bootloaders I can maybe update with?

Sorry, I made a mistake. Your bootloader matches the modem for am i747m from here: http://forum.xda-developers.com/showthread.php?t=1831898
Boot into download mode and look at the model number at the top.

Cool yeah it is a i747m you're right.
Once I install the latest (canadian) firmware, does that give me the possibility to flash mjb and the Ne4 to have access to the latest cm roms without any trouble? Not sure if i understand everything here...

Do not flash any firmware not specifically designed for the i747m. The mjb bootloader is for the i747 and flashing that on your phone would probably brick it.

Well thanks for the link. I updated my firmware and played with the apn and now the LTE works again and hitting an 80 mb download... pretty crazy.
So are you saying that a i747m would not be able to flash cm12(lollipop) which states in the nightly thread that it needs a NE4 bootloader/modem?!

You can determine which bootloaders are supported by CM12 by downloading CM12 and looking at the updater script in Notepad. The first few lines will list the supported bootloaders.
The latest stock firmware for the i747m can be found at sammobile.com. This firmware is flashable in Odin and would include the bootloader, modem, and the dreaded Knox.

[Q] HELP Updating bootloader on SGH-i747M

I am trying to update my SGH-i747M to run CyanogeMod. I have done this before on my Galaxy S2, so I am somewhat familiar with what I am doing, but am now stuck with a bootloader issue.
My CM Rom, GApps, are allready on the phones SD Card. I have installed CWM Recovery. I have backed up, and wiped the phone.
I am following these instructions:
http://wiki.cyanogenmod.org/w/Install_CM_for_d2att
There is a massive warning:
"CM10.1 and newer are not compatible with ICS bootloaders on this device. Update your device's firmware or you will get assert failures in recovery."
This is where I am stuck. Before I started this process, I let the phone on stock rom perform its latest software update.
When trying to install CM-11 I get assert failures. I can see from the script that I747MVLUEMK5 is supported by CM11. I assume this is due to bootloader. My current version is I747MVLUFNE6. I downloaded I747MVLUEMK5 and tried to install. I get the error "You cannot flash from your current bootloader.Current Version: I747MVLUFNE6"
I researched this thread:
http://forum.xda-developers.com/showthread.php?t=2321310&page=25
I figured I would try to dowload the second most recent version I747MVLDMF1 as I can see from the CM11 failure script that it is also supported. I cannot find it anywhere available for download. No download links I have found work.
I am stuck and do not know how to proceed. I thought this was going to be easy, and I am at the stage where I literally just install CM11, but cannot proceed. Please help.

Do not attempt to flash i747 modems and bootloaders onto the i747m and vice versa as this could brick your phone.
I recommend flashing the latest stock i747 rom from sammobile, flash the latest Philz, and then cm11.

Is there any reason to upgrade bootloader to anything newer that mk5? I have an i747m (Bell) with mk5 bootloader and modem that I have been running CM11 on for a long time. I am now running CM12 (actually CyanideL), and everything seems fine. Should I upgrade either my modem or bootloader? If so, to what?

Some of the newer ROMs require an up-to-date bootloader and modem.
If everything is working, no need to update in my opinion. If you decide to update, the safest way would be to flash back to completely stock, take the OTA updates until you are running the latest stock ROM.

How do I know if a ROM requires a higher bootloader and/or modem? Will it refuse to install/run?
Do more recent bootloaders fix bugs, improve effiencies or reduce battery drain, or any other tangible thing?

i upgraded from mj2 to ne4 and did not not notice any difference.
usually the OP will state if needs a higher version bootloader/modem.
"all i can really do , is stay out of my own way and let the will of heaven be done"

Newer isn't always better for some.
If you want to know if a particular ROM will run on your bootloader, you can either try to load the ROM or you can look at the ROM's updater script to see which bootloaders are supported.

i747 or t999

i have rooted and unlocked galaxy s3(i don't know if it is t999 or i747)the imei and boatloader are for t999 and the android build is i747mvldlk4 4.1.1 official rom and i want to flash new rom but i don't know what i have to flash (t999 roms or i747)please help me....

What does it day in download mode? What about the baseband/modem version?

Best way to know for sure is to install terminal emulator and enter this:
getprop ro.bootloader
You may simply have a T999 running on an I747 based rom. The two are very compatible when it comes to custom roms.
Since it sounds like you are on pretty old firmware, you will probably need to fully update it before flashing a newer rom. Just remember to only flash firmware for your model device. So if it's a T999 do not flash I747 firmware. Once updated you can then flash custom roms from either device.
(Also check the sticker under the battery to see what model it says)

baseband:t999uvdmd5 and modem board is msm8260a

What about the bootloader?

boatloader:t999uvdmd5

And just for good measure, check the sticker under the battery.
You are currently running on T999 base firmware with an I747 based rom, so you can be pretty certain you've got a T999 model.
You'll want to flash one of the two latest firmwares for the T999. (NC2 or OH1 if I'm remembering correctly) (note that some roms may not flash on the newest OH1 firmware if they have been updated recently, so you may want to go with NC2 to make things a little easier for now.)
After flashing your firmware, flash a custom recovery and then from the recovery flash your choice of rom.
Hope that helps and good luck!

thanks so much for help....but i want to ask about the files which i need to download when i flash nc2 firmware please(do i need to download any files for modem and kernel or this files are downloaded automatially with the firmware file??

When you are dealing with firmware, it includes everything, unless otherwise stated. Download and unzip the firmware package. Then flash the .tar.md5 file with Odin. Back up data first of course, just in case.
Doing this will give you a fully updated, stock, unrooted device. Reroot using Towel root, or flash recovery then a rom if you choose.
If you haven't already, I suggest reading the first few posts of my firmware thread (sticky in dev section). There's already a lot explained there.

does flashing t999uvuenc2 relock my mobile network..and if that will happens what can i do to unlock without code

Once the phone has been unlocked via code or the free method, the phone should remain unlocked after flashing ROMs.

Yup, the unlock is permanent. You can safely flash firmware, roms, etc.

ihave flashed cm12.1 d2tmo on my t999.but the features of camera like full HD video recording and face detecting were lost..can I restore them on this rom

[SOLVED] I think my i747M may be soft bricked?

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.

I747 doesnt reconigze the sim card after install custom rom

good afternoon, I have a Galaxy S3 SGH-I747 Model using ClockworkMod install the [ROM] [4.4.4] SlimKat d2att (at & t) Stable 9.0 and [Gapps] [4.4.x] Official Slim GApps TRDS (Slimkat) and now not recognize me the sim card. i bought this phone in amazon for use it here in Madrid. i dont know if is a Modem issue. I appreciate all the help you can give me. Thank you. (sorry for my english)

Does your sim card have a pin code that you enter each time you boot the phone? If yes, does the phone ask for the pin before unlocking the sim? What bootloader and modem are currently on the phone? Did the phone work before installing a custom ROM?

@audit13 , mine said "no service available" after moving from KK to lolli and i flashed a "write to extsdcard fix zip" and it fixed the issue , i.e. can now make and recieve calls. dont know if is same issue (or why exactly that fixed mine) but i have a KK "write to extsdcard fix.zip" if you think it would help.

Hey I have sgh-i747m canadian on stock jb . I flashed to CM 12.1 and my phone doesn't recognize sim. That means I can make calls and receive but no mobile data. Please help me

For the i747, sounds to me like the bootloader and modem are too old for the rom.
For theni747m, is the phone running the latest bootloader and modem?
@mrrocketdog, I've never heard about that zip until your helpful post. I must keep that in mind for the future even though I haven't had an s3 for quite a while.

The problem is the bootloader and modem. They need to be updated to work with the latest ROMs.
If the phone is sim unlocked, I recommend flashing back a stock rom using Odin and the firmware from sammobile, set up the phone, run ota updates until the phone is running the latest bootloader and modem. This is tedious and takes the most time but it is the safest method in my opinion.
If you don't want to go this route, just flash the latest modem and bootloader using twrp, flash the custom rom, flash gapps.

@Budare , here is the thread to upgrade bootloaders and modem if you decide on this route rather than flashing back to stock and running ota updates as @audit13 suggested , which IS the safest route. (always always always a certain % of risk ; no matter how small , to flash anything. not trying to scare you , just being honest)

thank you audit13, but how i run ota updates??

To run ota updates, you need to use Odin to flash the stock att 4.1.1 rom using Odin. After setting up the phone, check for software update under the phone settings.

i dont know if is because im in Madrid, but the phone doesnt get updates, thats why i want to use another rom. what can i do?

Not sure but I have received OTA updates even when the phone is not in the phone's original country. The OTA updates came over wifi.
If you want to use another ROM, you can install TWRP, boot into TWRP, flash bootloader, flash modem, flash custom ROM, flash gapps. If flashing the modem bootloader in TWRP, DO NOT reboot the phone in between flashing this files and make sure the bootloader and modem version are made for each other.
