Trouble Reconnecting! (Modem T889 on T889v phone)

Hey so im afraid im on the same boat as those who flashed a t889 modem on a t899v version of the note 2. I had fixed my signal and etc so now I have a working phone which although was a pain im glad I have a working phone. But for some reason whenever it looses connection to WIND HOME, it can never connect back to it untill I reboot the phone. ALSO when I try going automatically to search for a connection it either looks forever until a force stop or nothing happenings if I do manual it shows wind home and like 6 versions of WIND AWAY, no matter what I touch it will never register it even though it claims it is trying to.
Any help would be greatly appreciated. If it helps even though its the same error throughout what ever rom I use im using a t889 modem,with tweaked 2.5

You can brick your phone if you use a modem not intended for your phone. Just flash the T889v again.

flashing t889v modem warning!!!
According to this thread and personal experience, flashing the T889V modem will result your T889V phone in bootloop. See further details in this thread: http://forum.xda-developers.com/showthread.php?t=2119074

Has any one been successful in reverting to a T889V modem?
Also, once the T889 modem is flashed on T889V phone, does that unlock all the available LTE bands? For instance, would I be able to use the AT&T, Rogers, Telus/Bell LTE bands? Or would I need to flash specific modems for those phones?
Is there a custom modem file that would enable all the LTE bands the phone is capable off?
Are there any disadvantages to installing T889 modem on T889V? Would I lose anything?

Try flashing 4.3 rom from scratch (wiping dalvik cache, data/factory reset and cache partition) ? May be this will help fixing problem
If you want you can try Stock Rom - http://forum.xda-developers.com/showthread.php?t=2589891

Also make sure you have an APN set. @Bajanman has compiled a list of several AT&T APNs in his thread here: http://forum.xda-developers.com/showthread.php?t=2172110

I had a similar issue and this post helped me.

They are not hacking my friend...
Have you verified that your IMEI and EFS folder are normal ?
And have you verified your APN settings for your carrier ??
You mention flashing several roms on the device...
The items I listed will help you determine if any damage has been done....and also help you get service again...
All are knowledge you must have to prevent bad things from happening...
If your carrier did an official update to 4.3 while the device was rooted and running custom firmware....then you absolutely need to start fresh to clean the device up again...
Are you getting Knox errors or force close issues ??
Basically....in order to help you we need a detailed status of the device...
Software version....kernel version ....and baseband.....
The information is in settings/about phone/....and will tell us how best to proceed....g

Reading your first post, ATT flashed your phone to the latest update??? And changed the SIM? And that didn't work?
Why did you leave the store when your phone didn't work?

They told me they can't do nothing about it and the warranty was voided too.

Interesting. I'm asking questions I guess really dont matter.
But why was warranty voided, or was it expired?
Again more confusion.... Just wondering why they changed sim, flashed update, then told you to hit the street with a broke **** phone.
I can understand not replacing it, warranty whatever.
I took an Atrix2 phone into the shop, no working data. I had called tech support, they had OTA refreshed it, didnt work. Set me up with tier 2 tech support, more resets. Nothing.
Went into store, got another sim. Turns out it was simple. I had turned off the data plan awhile back until I was ready to give it to my daughter.
Got online, picked a plan. Data lite off.
Point is they worked with me to find the problem on a phone that was 2-3 years old.
You probably should follow me how to in this section and flash the stock 4.1.1 and go from there.

[Solved] [Q] Bought new S3 from Amazon, can't update

I recently bought a new "Samsung Galaxy S III 16GB SGH-T999L 4G LTE White - T-Mobile" from Oakland Wireless via Amazon. This is for my fiancé, to replace her broken iPhone 4s. After popping in her T-Mobile sim card, the phone seems to work fine. However, the WiFi calling feature seems to be missing and when we try to perform a software update it ends with "process failed". The installed Android version is 4.1.1.
She went to a T-Mobile store to see if they could help. They were also unable to get the phone to update, and eventually told her that it would never work simply because we didn't buy the phone from T-Mobile. They also told her it would only be a talk and text phone, and wouldn't get data service. However, this last part is clearly false, as she has been using data without any problem.
Does anybody have experience with this issue? Were the folks at the T-Mobile store correct or mistaken?
Also, assuming they are correct and the phone can't be updated over the air, can I just download and install a stock ROM with the latest version and WiFi calling? I have a custom ROM installed on my Galaxy Exhibit, so I am familiar with installing ROMs, but my fiancé doesn't want a custom ROM, she wants stock.

Look in the t mobile s3 section there should be a Odin file you can flash (stock firmware)
Sent from my SM-N900A using XDA Free mobile app

Well first of all the T999L released with 4.1.2 so something doesn't seem right, and it may be why its not updating. To get a better idea of the phone model, can you post a screenshot of the about device section? And I assume you are not rooted correct? Download this app https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo scroll to firmware info and post it here as well

Hmmm. Maybe I got the version wrong or maybe it's not really a T999L? She isn't here with the phone right now, so I'll have to get back to you.

I stopped posting the OTA's simply because they're next to useless for us. Fladhing the firmware via Odin has a much greater success rate snd OTA's are notorious for causing all sorts of problems. Just wasn't worth the trouble to post them anymore.

I attached the screenshots from the phone info app. Looks like maybe it's not the LTE model after all? I looked behind the battery, and it also says SGH-T999 with no "L" on the end.
The strange thing is that it shows an LTE mode in the network settings. However, I've never seen it actually use LTE mode, even though T-mobile says it should work at our location (Seattle). Using the Ookla speed test app, I get ~4 Mbps down (the same speed as my Galaxy Exhibit).
I'm thinking about returning the phone if it is not the correct model. I'm curious though, if I try updating the firmware and it doesn't work, can I restore everything exactly to it's current state before I return it? I don't want them to refuse the return because I messed with the firmware.

Ok looks like you got a Frankenstein phone.. That's an at&t bootloader with a Canadian product/model name & T999 build that I've never heard of.. I would just return it or ask for an exchange, not worth it to keep messing with it

Yup. Another one! And its got a csc from the I9300! The LEM build, if I remember right, was the original stock 4.0.4 firmware. But there is way too much conflicting info there for me to be comfortable recommending much of anything.
I just installed that app to make sure it wasn't giving bad info, and it is showing everything correctly for mine.
As for the LTE showing up in the menu, that isnt too uncommon. If you want to know what you are really connected to, check Settings, About Device, Status, Network Type. Best to do this during a large download.
But aside from it being a franken-phone, everything that is related to the T-Mobile model points to it being a non-LTE T999.

Yeah I noticed that too but guess I forgot to mention it ? so odd how out of nowhere there this wave of franken-phones going around

I-747 (AT&T) with T-Mobile ROM (For WiFi Calling)

Hi all, I have a AT&T I-747 S3 that is running CarbonROM (Aosp) at the moment. I'd like to flash a T-Mobile ROM onto it, so I can use native WiFi calling with my T-Mobile SIM Card.
Baseband: I747UCUEMJB
Bootloader AP SWREV - 2
I have the 4.3 Bootloader because I took the OTA update a few months back.
Does anyone have a T-Mobile ROM suggestion that will work and has WIFI calling?
Thanks all

All stock based T-Mobile touchwiz roms have wifi calling. Not sure itll work, but just give any of them a try. (NC2 is our latest build. Check out StockMod)

Thanks for the reply. I was concerned about bootloaders etc and didn't want to mess my phone up too badly. I was hoping someone would know what actual ROM would work with my specific modem/bootloader, since I think AT&T is much more locked up than TMO is.

As long as the ONLY things being flashed are the system and kernel, everything should work fine. You may have some minor connectivity issues, but I kind of doubt it since youre using it on T-Mobile's networks. Still, it is a possibility.
Anyway, just mske sure you never flash any base (or full) firmware or modem that is not specifically for the I747. Flashing the T-Mobile modem most likely just wont work (as opposed to bricking), but flashing T-Mobile firmware will almost certainly hard brick it.
Depending on the rom, you may need a d2tmo recovery. You probably wont run into that problem, but it is a possibility. It should be completely safe to flash the d2tmo TWRP or CWM recoveries if required though.
let me know if you have any other questions. also let us know whether or not wifi calling ends up working. Good luck!

I know this isn't the right place for this but I saw doc holidays name and know he's the man.but I have 4.1.2 and get get any kitkat rom to flash. I keep getting all types of error messages. How can I accomplish this feat. ..thanks and sorry again...please help...

I'm sorry, its been awhile since I've been on here. In recovery. It usually says error in sd card/ ...error 7. And also I can't seem to find a flashable boot loader. But besides that I can even get kk to flash period...thanks again

If you are trying to flash Touchwiz it wont work unless you Odin flash the 4.3 firmware

Usually cm...but the flash will give you an error and will abort installation because a bottloader isn't there...?...its not that my phone won't boot, I mean as soon as I flash it it will say opening package/installation...Then say something to the effect of error:/sdcard blah blah blah (error 7)...then say FAILED...

If its a Status 7 error it means you dont have a bootloader matching what they wrote into the updater-script. With CM it means its either too old, or too new. They dont update their scripts so when new firmware comes out it will no longer flash, regardless of whether or not it will work ok.
Try searching the rom thread to see if anyone ever posted one with a fixed script.
Or you can edit the asserts yourself.

[Q] Havent been able to load new roms after having to fix soft brick

First off I NEVER have had rom issues before this, it all started with a failed encryption attempt that soft bricked my phone. instead of re posting what i wrote here is a link to the 2 pg thread in which i received help and thus this is where i am at.
http://forum.xda-developers.com/showthread.php?t=2701706
OK now ever since then i have never been able to update to a new rom. I believe it let me do it once and i believe i am using an older version of S3Rx.
I believe it may be due to how I updated to 4.3 I would like to get 4.4 as i believe kit kat (tell me if im wrong) will probably be the last android os the S3 will support so i basically want to get the most out of it as i can and also be able to try other roms in general like i used to. Because i currently do not have a sd card I have yet to try anything drastic as i normally use my sd card for backups and rom installs because if something happens to the phone i have the sd card backup.
So in all What should I DO, I have fears of using Odin as the one time it failed on me i bricked a phone and I cant really afford to hard brick this one like i did the other. Although the only thing I can think of being a dumb leach user and non dev. Would be to use odin with the most recent root66 then go from there? Although again lol all i can think of is the above.
Thanks for reading and i hope like the last time I will recieve help to bring back the life to this device. TIA!!

Can you give a little more info on why you can't flash, like an error message or something?

HRM i guess im ok i just installed the latest S3Rx as i wanted to see what made it stop so i chose this rom (because i needed to update anyway) and it had aroma so I thought perfect ill know when it fails but it worked out ive downloaded and tried to install likewise several time at first i thought i got a bad download but ive tried again and for some reason. I have yet to try a 4.4 (i wanted to try likewise so thats why i chose it) so without trying other roms my issue has something to do with going to 4.4 from 4.3 IDK though as i have not tried other roms but no one else seams to have this issue with this rom port?
Any 4.4 rom suggestion to try to find out what the issue is?
currently installed base-band modem should have no impact on rom installation only the fact i wont get signal right?
I just cant think of any reason why i am having the issue?? any ideas anything i should check to make sure its right on my mobile? BTW thanks for coming back to help as this is possibly a stupidity problem which is hard to help how do you help stupid lol?

Try S3rx 4.4.2 or do you mean aosp/cm?.. And correct, baseband/modem won't matter on ROM installation.. I'm sure it's not stupidity, believe me we all get issues we cannot understand at times and the next time you try, problem is gone lol

i personally prefer touchwiz so no aosp or cm and the latest version of s3Rx i though is what i just installed but its only 4.3 not 4.4
http://forum.xda-developers.com/showthread.php?t=2326763
installing that works but i still cant get to 4.4 im going to search for one that has aroma maybe it will work do you have any suggestions on a good touchwiz based rom on the latest version of android?
To me Likewise looked the best but trying to get that rom working is what prompted this OP.
I still have yet to try again after this recent rom update as I havent had the time and the battery level is not high enough yet to start as i will need to create a new backup and delete my old ones as i have the 12 gb model and currently no sd card.
I will post back when that has been done to show my results. In the mean time ill be searching for another possibly suitable rom like i already said something with aroma and if you have a preference ill try that first.

You could be on a 4.3 ROM, but have a 4.1.x bootloader.. Download latest 4.3 firmware for your device and flash it with Odin

So yes i must be on 4.1.2 as that was the last time i flashed with odin so i believe you help3ed me with my main isssue now this is something i would like to be sure of:
Can i simply flash the following posted on the s3rx page or will i have to use odin i prefer not to as well i don't know much about it and it scares me as idk how to if possible backup in case of error as the only unfixed problem i have ever had was a while rooting a galaxy s 4g (the one that came with inception) and i walked away and the cord was unplugged and there was an error that it still has about firmware upgrade failure connect to kies and neither kies nor odin will connect to it so its currently in the same situation. So i am fearful of using odin unless it must be done.
Complete 4.3 T999, T999L and T999V bootloader and modem packages.
After flashing DO NOT try to install any older bootloaders or use any other odin.tar other then the latest 4.3 or you will brick your phone.

Would this be enough (would probably use NC2) or will i be better of using the latest root66 with odin? and if so can you give me some tips on odin usage as i would get the latest odin and the latest root66 rom and flash it hoping it works I would try to learn more also but yeah.

It's better to flash the full firmware with Odin imo, but it should be fine. And yes, use nc2

So i think the best cleanest way is to use odin although i have a few questions
First the latest version of odin should work right so 3.09 or 3.10?
Can a backup before this? is there a way to do it?
Lastly the best rom to flash is root 66 NC2 fot t999
Then i will be on a 4.3 bootloader and will be able to use 4.3+ roms?
I have the drivers the latest odin and the root66 image can you direct me on how to do it as a refresher?
I appreciate all your help!!

Please go to Android development an look at [baseband] an just go to first page should help with everything

I believe the root66 thread has instructions
