I'm trying to use galaxsim unlock to unlock my I9195. The app says that I need a baseband ending with MJ7 or older.
At the moment the phone is on stock firmware
I9195XXUCOD3, which is android 4.4.2.
I have tried using Odin to flash two different modem files, one is a MJ7 modem file that I downloaded on its own, the other one is one that I extracted from some older 4.2.2 firmware. In both cases they flash successfully, the phone boots up, but there is neither mobile nor wifi connectivity. I assume that this is because the older modem file is not compatible with the newer firmware? I have successfully extracted modem files from stock ROMs and flashed them in the past, so I'm fairly sure I'm doing that bit properly.
I have also attempted flashing the older 4.2.2 firmware in it's entirety, rather than just the modem file, but it won't flash because the bootloader is older than the current one.
Any help for how I go from here would be greatly appreciated.
edit: i have also now tried flashing the I9195UBUBNE2 brazilian firmware that allows for downgrading from 4.4.2 to 4.2.2. even with this firmware, there is still no connectivity after i flash the MJ7 modem. so as far as i can establish, any MJ7 or older modem is not compatible with the later bootloader?

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.
Hello experts,
I need an explanation for the following issue:
- M919 flashed via Odin with NK2 stock firmware
- flashed TWRP via heimdall
- flashed Mokee firmware via TWRP
- baseband is changed to M919UVUFNB4
Now I flashed my wife's M919 which is on M919UVUEMK2 with Mokee but the baseband stays at MK2. Why?
Do I need to flash her phone to NK2 and then flash Mokee to get the M919UVUFNB4 baseband?
Why would you want NB4 baseband?
You may have had mismatched baseband /bootloader on your phone to begin with.
You should always have the latest modem running NH7 or NK2, even if you downgrade bootloader.
Pp.
The point is why was the baseband downgraded when I flashed Mokee on my phone but not upgraded when I flashed Mokee on my wife's phone?
Mokee roms will not install modem or change firmware, these are not included in the rom.
Your baseband must have been at NB4 before you flashed mokee.
Its possible that when you flashed the stock firmware the modem didn't stick and stayed NB4.
Your wife's phone had the matching baseband /firmware already, so it stayed the same.
All you have to do is flash the nk2 modem on your phone using Odin and you'll be all set.
Pp.
@PanchoPlanet: Yes you are right. While flashing the stock ROM NK2 the modem didn't stick. I had to flash it 3 times on my phone and 2 times on my wife's phone. Now they are both on NK2 baseband. But unfortunately that didn't solve the low WiFi signal on my wife's phone...
If you can see a side by side comparison of both phones on the same wifi network and one has more signal than the other, you may be having a hardware issue with your wife's phone.
Hardware related could be the physical radio on m/b or the antenna wire.
Find a wifi analysis app in the play store and run it on both phones and check your readings.
If they match it could just be that the displayed value could be off.

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
I have a Canadian Galaxy S3, on 4.1.1 DLK4 Official. I rooted it, and have TWRP.
I want to upgrade my rom to a CM12/13 but of course with root and custom recovery, OTA updates are blocked.
I need newer bootloaders and modem to run the newer android versions.
Should I install them now, while on 4.1.1, and then flash CM12, or should I sequentially update each of the AT&T firmwares until I get up to 4.4.2?
Do official roms have the bootloaders and modems in them and install them automatically?
Should I use the Kies restore method?
The Canadian and att s3 phones are not the same model number. Don't flash an att bootloader to your Canadian phone as this may brick the phone.
Flash latest stock rom from Sammobile.com, flash twrp, flash cm.

Okay, but i can use AT&T roms tho?
The i747m will work with d2can, d2lte, and d2att Roms.
Is it safe to flash straight from 4.1.1 to 4.4.2 using a sammobile rom? will i brick due to Knox bootloader and modem?
Can I flash it using TWRP?
If someone could link a tutorial that would be very helpful.
I keep reading stuff that says to flash the newer bootloader before flashing a 4.3 firmware, and some that say the opposite. Others say that people should incrementally update.
I want to go from 4.1.1 original with Root and TWRP, to CM13.
Thank you.
Yes, you can flash the latest stock 4.4.2 rom from Sammobile.com directly to your phone. No need to do anything other than backing up your data.

Now I just need to get the balls again to use odin. Flashing the custom recovery using the Universal Tool Kit that had step by step walkthrough was adrenaline rush enough LOL.
I could also use Kies, as that has 4.4.2 OB3 (telus), and also has "emergency firmware recovery" feature if a brick ever happens. Though ideally the only time boot.img gets flashed is only with Full Stock Firmware files.
I find kies to be unreliable when I have tried to restore firmware so I always stuck with Odin.
I'm using a SGH-I747M (d2can) phone can flashed a d2att LineageOS rom. Everyone works except data. I'm able to receive/send texts and phone calls without issue. I've read that I may need to flash my modem, however I can't find a mirror anywhere. There was a complete list posted here a few years ago but all the links are dead. First of all, do you guys think it's a modem issue, and if so, where can I find the correct one to flash?
Edit:
So I've downloaded stock firmware and tried to extract the modem.bin file in order to flash it, but I can't find. I unzip the firmware, extract the md5 file, extract the NON-HLOS file, which has a bunch of modem.b01 files, but there's no modem.bin anywhere. Any advice?
Was the phone running the latest stock i747m ROM before flashing Lineage?
It was running a stock ROM, but I don't think it was the latest. I rooted the phone and Samsung stopped pushing updates because it was tampered with. I installed a stock rom (4.4.2) on the phone and it seems to be working okay, however is there anyway to install Lineage OS with the right modem?
The latest modem and bootloader is all that should be required. There is no specific modem that is made for Lineage.
Have you tried a different version of TWRP?
Does anyone have a link for lineages 14.1 sgh i747m? The links at official website aren't working.
