Upgrading baseband from NE4 to NJ2 - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I haven't upgraded my baseband/modem since I was running S3RX, so I am on NE4 baseband currently. I have been running CM12 for some time now and have no plans on going back to KK.
So I'm wondering what the best way to update to NJ2 would be. Should I download d2att_I747UCUFNJ1_bootloader_modem_4.4.2_12-3-14.zip flash in twrp, reboot then flash d2att_I747UCUFNJ2_bootloader_modem_4.4.2_8-19-2015.zip?
thanks!

That matches what I did when I updated from MJB -> NE4 -> NJ1. Download enewman's zips that bundle the bootloader and modem together. Flash sequentially, and reboot into your ROM between each bootloader/modem flash.
I haven't updated to NJ2 yet. NJ1 is working fine.

Need help - still on 4.3 MDL bootloader, I want to grade to 4.4.4

Hi.
I'm really out of the loop for flashing to the latest rom. I'm still on 4.3 Darthstalker Version X1. I want to upgrade to the latest 4.4.4. I've try flashing a few roms but I couldn't get the wifi to turn on so I want to know what I'm doing wrong.
I've flashed the NH7 modem.bin from Shinnyside's thread. I didn't flash the non-HLOS file because after flashing just the modem.bin file I can see the NH4 modem is sticking and everything still work on 4.3. I then flashed a few different rom but I couldn't get the wifi to turn on. Is it that I'm getting this problem is because I didn't flash the non-HLOS modem? If I flash the non-NLOS file, will it solve the wifi problem I'm having?
I also read some post that I need to update to the NH7 bootloader (i'm still on the mk2 bootloader) for some 4.4.4 feature to work. How do I do that?
Thanks in advance for your help.
Either try a different kernel or update to NH7 firmware, then flash ROM
Hi serio22,
What kernal can I try? How to I update to the NH7 firmware? Thx.

I believe CM11 will work fine with 4.3 firmware and modems. I would suggest using the MJ2 firmware and MJB modem, at least until you have decided you need even newer than them. An advantage to MJ2 is that it can be downgraded if you ever have need for that. A link to it can be found in the OP of http://forum.xda-developers.com/showthread.php?t=2252932. Another advantage is that it was released prior to the release of KNOX. Not only will this firmware/baseband combo will run CM11, it will run TW based 4.3 roms and many TW based 4.4.2 roms.
If you are wanting to get to the latest firmware and baseband, do not use the MJ2 firmware. Many people would recommend you upgrading sequentially through MJB, NE4, and to NJ1. Links to the MJB firmware can be found in the same post as the MJ2 I linked. Enewman17 has a thread regarding upgrading to NE4 firmware. http://forum.xda-developers.com/galaxy-s3-att/general/ucuemjb-to-ucufne4-firmware-update-t2808654
If you have an interest in unlocking your phone from your carrier, do it prior to upgrading to MJB and beyond. Once reaching MJB it can only be unlocked by your carrier or by using a paid service.

If i was to flash NE4,should i flash MG2 to MJB first and then flash NE4?
And also,do i have to do a factory reset while flashing these files?

Yes, I would recommend incremental updating: MG2 > MJB > NE4; as shown in the second thread I linked.
I am only on the 4.3 leaked firmware and official 4.3 baseband, I have not updated to NE4 at this point. But, I was on the 4.1.2 stock rom when I updated to the MJ2/MJB firmware-modem combination. I went back into that rom with no factory reset and no wipes. After a couple of days with no issues I flashed a custom 4.3 rom. I did do the recommended reset and wipes in the flashing process, that was due to the rom, not the firmware and baseband. Also, the link does not suggest resetting or wiping in the upgrade of firmware and modem. If you have any issues after flashing, then I would suggest the factory reset and wipes with possibly even a reflash of your rom.

i personally have never flashed one of the cm12 unofficial builds. i suggest you read thru the threads and see if people are having issues or not and then decide. i would also definitely make a backup of current setup if did decide to try.
if you did a full wipe between unofficial and official , i would imagine to be most sure way to avoid errors.
imho there is ALWAYS a risk in flashing/rooting/modding,etc.
good luck with whatever you decide.

[Q] New to AT&T S3, have a few quick questions

I just bought an AT&T S3 to replace a carrier unlocked T-Mobile S3. The new device is already rooted with CM11 installed and it's baseband is MG2. I'll need to revert back to stock temporarily to do a carrier unlock. Here are my questions:
What is a safe TW (preferrably a pre-rooted TW) I can flash to perform the carrier unlock?
After I'm carrier unlocked, what is the latest modem I can install? I want to do all of this without enabling knox.
Thanks to all in advance,
Niphoet
Flashing back to stock means everything will be wiped on the phone, including recovery and data.
You can use Odin to flash the stock ATT 4.1.1 firmware from sammobile.com. Before doing so, boot into download mode and make sure you there is nothing about warranty bit on the screen.

There ae several important things to know about upgrading your modem and firmware.
1) KNOX comes with all of the firmware since the officlal 4.3 release, MJB. The leaked version of the 4.3 release (MJ2) does not have KNOX.
2) Once on the MJB and later firmware you can no longer downgrade, you will most probably brick your phone.
3) It is possible to run the MJ2 firmware/bootloader and MJB modem combination on 4.3 and 4.4.x ROMs.
4) The MJ2 and MJB bootloader will most likely require a custom kernel if you use it on 4.4.x ROMs. Something like the kToonez kernel or iBuddler kernel found in Likewise.
5) Once you get past the 4.3 firmware do not mix firmware and modem release versions, again bricks are probably. If you have NE4 firmare, use the NE4 modem. The same goes for for if you have the NE4 modem, use the NE4 bootloader. This holds true for NH2, NJ1, and NKx.
6) The only time I have seen that you absolutely must be on NE4 or newer is for the Lollipop ROMs.

[Q] Upgrading baseband version

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.

Question on upgrading bootloader and modem on i747

I currently have bootloader and radio at version I747UCUEMJB that I would like to upgrade all the way to I747UCUFNJ2.
Can I do a jump from MJB straight to NJ2 or I would need to upgrade sequentially ie MJB->NE4->NJ2?
Also, I found this website: http://androidromupdate.com/att-samsung-galaxy-s3-sgh-i747-odin-stock-firmware/ and it has the links to the NE2 and NJ2 firwares, however, the file's size is about 900MB. Does modem and bootloader really need 900MB or is the file actually bundling everything together ie modem+bootloader+ROM = 900MB?
If latter, where can I find working links that only offer the modem and a bootloader to be flashed?
Thanks!!
The safest way would be to use Odin to flash this full NE4 firmware update. Once you're up on stock NE4, you can take OTA updates. You'll go from NE4 -> NJ1 -> NJ2.
enewman17 has posted everything you need to update manually linked to this thread. If you go this route, read that thread carefully, then read it again and make certain you understand it. You have to update sequentially MJB -> NE4 -> NJ1 -> NJ2, and you have to reboot into system between every firmware update. Be super careful if you go this route. This phone is easy to hard brick when messing with bootloader and modem.
@jason2678,
Thanks for a reply. I was using this site: http://androidromupdate.com/att-samsung-galaxy-s3-sgh-i747-odin-stock-firmware/ as my main software source and the available android software goes straight from NE4 to NJ2. So just to double confirm, I can not make a jump from NE4 straight to NJ2, correct?
I tried to do OTA while on NE4, but I do not get any update push notifications. It says all of my software is up to date.

No, don't try to go straight from NE4 to NJ2. It needs to go NE4 -> NJ1 -> NJ2; the firmware order is in the bottom of enewman17's first post in his firmware thread.. Update the firmware sequentially, and do a full reboot into system in between each firmware update.
The full reboot part is faster if you are using a custom rom as you update because if you try to update firmware without updating a Touchwiz rom it probably won't boot.
I think I start to understand.
updates NE4->NJ1 and NJ1->NJ2 are not updating everything in the Android. Those are just some *incremental* feature enhancements to various facets of OS, bootloaders and modems; hence, it now makes sense why their size is so small.
Q. Does this mean I will not lose any personal settings/apps/etc in my already configured OR it resets and I will have to re-install the apps?
Also, can I use Android's recovery (Volume UP + Home) instead of suggested TWRP or CWM? is there a reason why we should do it through custom recovery?
Lastly, I read somewhere that both modem and bootloader must be of the same version. When I do 'adb bugreport', I get
Build fingerprint: 'samsung/d2uc/d2att:4.4.2/KOT49H/I747UCUFNE4:user/release-keys'
Bootloader: I747UCUFNE4
Radio: msm
However when I use PhoneInfo app, I get
Bootloader Version: I747UCUFNE4
PDA Version: I747UCUFNE4
CSC Version: I747UCUFNE4
Baseband Version: I747UCUFNE4
Latest Firmware: N/A
Q. What is Phone: msm? I thought Phone should be equal to I747UCUFNE4 as well.
Can I or can I not proceed with an installation of the NJ1 given my current spec?
Also, some random questions:
1) Will my present OS work with NJ1 or NJ2 ( I am currently on NE4) or do I need to update the OS as well?
2) if I need to also install the NJ1 ROM,
will I need flash bootloader first, reboot into NE4 OS, reboot again into recovery and install NJ1 ROM
OR
I have to install bootloader and ROM, all at the same time within the recovery without any reboots?
Thanks!

If you're running a stock rom, you need to reflash it at each step. With stock roms, you need to use the NE4 rom on the NE4 modem, the NJ1 rom with the NJ1 modem, etc. If you don't update the rom too, then it might not boot if the rom doesn't match the modem. Even if it does boot up, you'll likely have problems like wifi not turning on. I'm not sure if you can "dirty flash" those rom zips without wiping (and keep settings and app data), or if that will fail to boot. I'd search the enewman thread for help on that. When I used these I was running CM 12.1, so I didn't have to mess with the rom. Custom roms are more flexible than stock roms in what bootloader/modem they'll work right on.

Sounds to me like you're on the NE4 bootloader, modem, and rom. You can confirm by entering this in an adb shell or a terminal app:

Nope, an NE4 rom might not boot on NJ1/2 firmware, and even if it does boot up something will be screwed up like wifi not turning on or no mobile data. To make it easier I'd just flash LOS or OctOs before messing with bootloader/modem. LOS 14 should boot on any kitkat bootloader/modem (NE4, NJ1, or NJ2).
Touchwiz roms can be finicky about booting up sometimes, first boot will last 10 - 20 minutes on a new rom, and you don't want boot to fail in between these bootloader/modem flashes. To keep it simple and faster, I'd just run a custom rom like LOS while you're updating even if you go back to stock NJ2 once you're done and everything is up to date.
@jason2678,
Thanks for your reply with the details and adb how-tos. Adb confirmed that both my bootloader and modem are indeed I747UCUFNE4. Not too long ago I flashed NE4 (CP, AP, BL, CSC) via Odin and it was very encouraging to see the same results via adb.
From what I gather, all in all, the amount of risk/benefit ratio is quite high in the context of moving from NE4 to NJ1.
Yeah, I was on LOS14 before and it was very extremely choppy on my i747. OctOs was much smoother but the dialer would not open up and image processing (photo viewing) was not very good. So that is why I flashed everything to stock NE4.
Few more questions..
I see the link for the rooted NJ1 rom, but are there unrooted NJ1 Roms available or do I have to unroot myself?
If I decide to proceed to NJ1, do I install BL/CP and ROM at the same time or I install CP/BL first, reboot and then ROM?
I see that there are two flavors of NJ1 BL/CP. One is 68MB and the other is 19MB. Which one do I use?
Thanks,

Sorry, I'm entirely certain how to go about flashing those bootloader/modem combos with stock ROMs. Those details might be covered in enewman's thread. If I had to do it, I'd just flash OctOs and set it up first, so the reboots would be quicker and it would work with any of the modems.
I flashed that nj1 rom once. It's not actually pre-rooted. It asks if you want to root after it flashes system, so you can choose not to root it.
I don't know why there would be two different nj1's. Maybe one is just the modem and the other is bootloader and modem? I'd pick the one with both bundled. You always want them to match on this phone on the firmware with Knox. Only flash stuff enewman packaged. He's the man for i747 firmware.
Yes, for for sure - I want to use only enewman's packages. The thing is: in his post at https://forum.xda-developers.com/galaxy-s3-att/general/ucufne4-to-ucufnj1-update-t2941792
he lists two NJ1 bootloader/modem files from what I can understand.
1) 68MB https://www.androidfilehost.com/?fid=95784891001611091
2) 19MB https://www.androidfilehost.com/?fid=95832962473396872
Still trying to figure out which one to use...

Sorry, I'm entirely certain how to go about flashing those bootloader/modem combos with stock ROMs. Those details might be covered in enewman's thread. If I had to do it, I'd just flash OctOs and set it up first, so the reboots would be quicker and it would work with any of the modems.
I flashed that nj1 rom once. It's not actually pre-rooted. It asks if you want to root after it flashes system, so you can choose not to root it.
I don't know why there would be two different nj1's. Maybe one is just the modem and the other is bootloader and modem? I'd pick the one with both bundled. You always want them to match on this phone on the firmware with Knox. Only flash stuff enewman packaged. He's the man for i747 firmware.

Pretty sure the 19.8 mb one is the one I used.

@jason2678,
Thanks!! I will use the 19.8MB one then.
Just burned TWRP over the stock recovery.
Tomorrow I will go to Samsung Experience center over at Best buy. I heard that they bring samsung phones to the most recent available updates. We'll see how that will go. If this route will not lead anywhere, then I will burn NJ1 and NJ2 myself.

So I went to Samsung Experience Center and guess what? My phone got upgraded from Ne4 to Nj2 directly. It took about 15 minutes. So all is working right now and I am happy to have the most recent update. It was really interesting to observe how they do it. After they connected the phone via USB and clicked something on their computer, the phone went directly from GUI into download mode without ever rebooting. I suppose they have some keys that open up a whole range of options on the phone.
The only problem that I discovered, and this has nothing to do with an upgrade, is that kit Kat is missing WebView and Google no longer supports WebView for KitKat for 442. Looking for alternatives now....
Thanks again, @jason2678, for all your help! I learned a ton. Thank you, Samsung Experience Center , for making things so easy for regular folks (who just want to use their up-to-date phone) like myself!!
