[Q] Basebands on 4.3+ - T-Mobile, Samsung Galaxy SIII

Hey guys,
So I odin'd the the latest stock T999 firmware UVUEMJC. Everything went smooth but when I had installed other ROMs like CM11 or Carbon 4.3.1, I'm not able use any other basebands except for UVUEMJC. It won't connect to data at all if I use another baseband. Am I only able to use the UVUEMJC baseband or did I forget to do something?

Check your APN. If its set to epc.t-mobile.com.
Someone else recently reported the same case. Possibly it does not let you flash another modem.

So when I would flash the UVUEMJC modem, all the APN's are there but when I flash any others they're all gone.

In that case use APN Backup & Restore to make a backup while on UVUEMJC.

[Q] Flashing Stock Rom

I want to flash back to stock rom 4.1(cant recall if 4.1.1 is the newest one or not) in a similar manner to how I flash to custom roms such as:
MAKE A NANDROID
Boot into recovery
Wipe data/factory reset, wipe cache, and wipe dalvik cache
Flash ROM
Reboot
I'm currently on PA ROM stable. So here are my questions
1) Can I flash like this instead of going through ODIN and losing root etc
2) Can I keep my root and flashing this like a custom rom, but in actuality a stock rom
3) If this is possible can ATT stock rom work on Roger's i747m, i suspect it would as long as i dont touch the modem. Not sure if there will be LTE issues.
I couldnt find anything on XDA or google, it seems that all stock revert it to original setting and no root.
Thanks

Well i must hang my head in shame for not being able to find this.
This is a good way of flashing a "custom" stock rom without odin and keeping root.
Have you heard of any issues (LTE or any other) with ATT stock on Canadian i747m?
THanks

You'll have to flash the stock for your carrier if you don't want issues.

It's just that I noticed this part of the forum referred to AT&T, Rogers, Bell, Telus, I wondered if they would be interchangeable.
A lot of the ROMs out there like CM10 and AOKP support ATT but can be ran on canadian i747m's, so thats why I was wondering if ATT stock can run ok on i747ms
EDIT: in beerdroid's link he did enter "**WARNING!** All information and attached links are for the I747 and I747M ONLY!"........so I'm going to assume that the ATT stock rom can run on i747m's without issue.

I think it would be for the most part, would just have to change the modem (I think?).
Either way, always safer to go with your carrier's.

Good find. I had forgotten about that one.
Typically, if you flash an att modem on a Canadian phone it will destroy the imei. I would think that the same would be true for Canadian modems on Att s3's.

[Q] No Wifi or 3G on LG Optimus G LS970 (Sprint) with Kitkat, stock works

Hi,
My LS970 works fine with the stock ROM (4.0.4) but as soon as I install a custom ROM with Kitkat neither 3G, 4G or Wifi work. I have tried CM11, JellyBam and SlimBeans but all show the same behavior. Does anybody have this working or an idea what could be wrong?
Cheers!

If your on Stock 4.0.4 that should be ZV9 and that radio won't work for JB and any CM Rom's. You need to upgrade your radio.
There are a few options:
Let your phone upgrade to ZVC. It should be trying to do that already.
Or, if you are rooted and unlocked already and have TWRP, then you can flash the radio/modem. I would also recommend using a Stock based Rom to start.
The flashable radio/modems are here. http://forum.xda-developers.com/showthread.php?p=40169203
The Stock Rom I would use is here. http://www.androidfilehost.com/?fid=23212708291680187
So in recovery, flash the radio, then the ROM. It might not hurt to flash the radio a second time before you reboot.

I couldn't go back to stock and use the OTA because I have been told that using the OTA stock update will brick the phone if the bootloader is unlocked. So I have downloaded the file LS970ZVC-M9615A-CEFWMAZM-3.0.10646 from your link and flashed it.
WIFI works now. Thanks! But I still don't have 3G or LTE. Any ideas what else could be missing?
Thanks again! I was already ready to throw out the phone and get a Nexus 5.

Try flashing a stock rom, the one linked above. Then go to Settings>System Updates and update profile and prl. You can also go to Settings>Activate this device after those 2. This is the only way we can update those. CM/AOSP can't do that. That should get you going.

Sometimes I have to dirty flash "flash rom zip again over top of original flash" without wiping dalvik or anything to get signals to pick up and I'm current on Zvc , prl , ect. Never hurts anything and always seems to work if the traditional way doesn't, if you see this problem again might try.

try a factory wipe/reset maybe? you'll still be rooted after that...couldn't hurt till someone else may chime in
this is also why you always, always, always make nandroid backups via recovery before doing anything to change your system

damn...hopefully someone can help you out before I would say use my 2nd link in my signature and completely reinstall the entire 4.3 operating system and then root all over again...did you attempt while on the stock rom, going to settings>more>system update and then update your prl and profile?
edit...actually, you can try this, 4.3 mk3 stock roms already rooted...see what happens, it has some other stuff too in it that might help you out with your errors:

PRL and Profile reset-from the dialer on a TW ROM, dial ##72786# it will reset itself after two automatic reboots (don't touch anything while process is occurring).
Do you mean I should flash tw rom first ?
Then call ##72786# and the phone will work fine as before
Can I flash tw rom because my stock rom is 4.3 ?
And I hear that if we have 4.3 rom we cannot downgrade to anyrom

Yes, you need to be running any TW based ROM (stock, Wicked Sensations, MOAR, etc.) to run a PRL and Profile reset from your dialer, this function does not work on AOSP based ROM's. Hopefully you have a backup of your stock ROM, otherwise you will need to download one, and be patient because the file size is huge.
As to the second part of your post, stock is TW, and the downgrade rumor is only applicable if you 1) Have the Knox bootloader and 2) try to use Odin to change to a different firmware version that contains a non-Knox bootloader. You can flash any Android version of any ROM that you want when using custom recovery like Philz Touch.
Are you on 4.3? If so, no modem lower than MK3 will give you data if you do that
thank you guys and especially mr struck i already make the phone work again after dial ##72786#
and also i use someone trick that i should take out the battery for an hour after dial the code , so i take it out for a whole day and when i try the phone everything is working normally again.
thank you

That does not resolve the problem, the problem is the 4.4.2 kitkat and 4.3, Im having that signal issue also, and I have tried other firmwares. I also have a Note 2 and when it runs 4.1.1, this version has no issue. The new firmware with the modem inside it, its what causing it the problem. Your best bet is, as I have posted in a few section is for someone to make a back up copy of the QCN, of the original stock M919V modem file QCN, its very easy to make a backup of the QCN, with that we can reflash it in QSPST and make the AWS work, I need someone here with a videotron s4 model M919V to make a backup copy of the QCN file so we can try it out, if not we need to wait till they release a newer version. My model is the S4 but my model is i337M, but you can flash the M919V firmware because its the same modem inside it, NE1.

[Modem][Baseband]4.4.2 Modems for I747/I747M

WARNING!!!!
Do not flash a 4.4.2 modem if you are running 4.3 firmware (bootloaders)!!!!
This will cause a permanent hard-brick!!! There is no fix!!!​
The only reason anyone should need to flash one of these is if they had flashed a 4.3 or earlier modem for whatever reason. Once updated to 4.4.2 firmware, ONLY that matching modem will work. Flashing anything else will result in no signal and most likely an "Unknown" baseband and IMEI. If you flashed an older modem, you will need to flash back to the 4.4.2 one and these will all come back.
This has happened a number of times already, and continues to happen still. So I figured I would put them in a separate thread to make them easier to find.
Flash from the recovery of your choice, or Mobile Odin. The updater-script for these includes an assert that should prevent flashing on anything that does not have the correct bootloader.
Full Disclosure: I do not have an I747 or I747M, and as such, I am unable to test any of these. I have full confidence they will work as expected though. (I have been doing the modems for the T999 for a couple of years now). Still, you should know they are currently untested.

These modems will only work if you have updated to the latest 4.4.2 base firmware and bootloaders. The ROM you are running is irrelevant. If everything is currently working, you have no need for these.

Hello Doc, I have an issue trying to upload the modem on my sgh i747 because when I downloaded the CWM modem gives me Error 7 and dont let me upload the modem actually I have I747UCUEMJB and 4.4.4 slimkat, but my bigger problem is the imei, baseband null. helpme please all the night I wastryng many solutions and I am so tired now.. thanks
You probably never updated your firmware to 4.4.2.
To know for sure open terminal emulator and enter this.
getprop ro.bootloader
If it says MJB, you haven't updated your firmware yet and flashing this modem would permanently break your phone. If it is MJB, flash the same firmware via Odin and factory reset. That often fixes the imei problem. If it does not, pm me for further help with it. Can't post those instructions here.

Thanks for keeping the support for this phone going. I have the latest bootloader ..uemk5 for my Rogers sghI747m.
I tried to flash this and got a status 7.
I have been using the ..UEND3 Modem up till now.
You need to update first or this modem would permanently brick your device. MK5 is a 4.3 build. I think the latest Rogers is NF2. You cannot flash this modem unless you've already updated. And then you won't need this. I released these because some mistakenly flash the older 4.3 modems after updating and find it won't work, so they needed a way back.

No Cell data after root and new rom and recovery.
Hi,
This is a repost from the S3 help forum as the OP here seems very knowledgeable about modems and bootloaders. Excuse the redundancy.
I was given a used ATT I747 s3 which had stock 4.3 , modem/bootloader mjb, and knox. I rooted, removed knox and installed slim 4.4.4 rom, lean 4.4.4 kernel and latest philz recovery. All running ok
including cell calls to/from phone, mms, apps and wifi data. Same modem/bootloader (MJB), IMEI accurate after upgrade. However ATT cellular data will not connect and or transmit and/or receive using att, phone or lte APN.
Any help/thoughts appreciated?
Could be the rom. I've been hearing about a lot of connection issues on cm/aosp based roms lately. Try flashing back to stock to see if it works.
Sent from my SAMSUNG-SGH-I747 using Tapatalk
Nevermind I re read. Did it work before you installed lean kernel?
Sent from my SGH-I747M using XDA Free mobile app
In my upgrade process, the first thing I did, after the recovery had been updated to Philz, was install slim rom and lean kernel together and at the same time. That was when the problems began. They went away when I reinstalled slim rom only (without lean kernel). Everything now ok. Hope that helps.
I'll start by saying I'm very much a noob but read and read as much as I can and have been following quite closely a lot of the s3 development so anyone feel free to correct me if I'm wrong.
It seems in the past few months a lot has changed with kernels and compatibility has broken numerous times. If the dates of the releases of kernel and Rom aren't quite close then some commits in the rom could break data, wifi, etc. If your running the latest nightly Rom make sure your using a recent kernel. Always just make a backup before flashing custom kernel and then you can revert right back if the kernel breaks anything.
Hope that helps...
