Trouble Reconnecting! (Modem T889 on T889v phone) - T-Mobile Samsung Galaxy Note II

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?

Note 2 I317M AWS Issues

Hello everyone,
I picked up a 2nd hand white Note 2 I317M, Canadian variant, with the intent of using with Mobilicity, which uses AWS 1700 bands. So, after I got it, I applied this mod to enable AWS http://forum.xda-developers.com/showthread.php?t=2068041 . Unfortunately, even after flashing the QCN file, the phone did not detect Mobilicity. I rooted the phone and installed skynote 8 ROM then flashed the QCN file to unlock the AWS bands, it still didnt detect Mobilicity. I then followed this guide here http://forum.xda-developers.com/showthread.php?t=2026569 and installed a T-mobile ROM, then flashed the QCN file, and it still didnt detect Mobilicity. The only networks it shows are CDN ROAMING (aka Rogers), TELUS, and some other network I cant remember. I even downgraded to stock 4.1.1 and applied the QCN, with no luck. I have two friends who have Canadian i317M Note 2s, with the AWS QCN patch applied, and both of them are using them on Mobilicity and Wind with no issues whatsoever. Does anyone have any idea whats going on here? Please help
Thanks!
EDIT: Also want to mention that earlier today when I had Skynote running, the phone connected automatically to Mobilicity after leaving it by itself for a long while. However, it couldnt call or do anything, and signal strength was very bad. After I did a reboot, the phone wouldnt find Mobilicity anymore

I just followed the instructions on the other thread by flashing the att dumimei file using qpst. I tried almost everything possible (with the exception of manually changing the nv parameters) with no luck. So i just sold it and got a t889 aws model

I downgraded mine to 4.1.1, flashed it with the one you used (att dumimei ) and it worked!
Your post was the very first one that showed up on google when I searched I317M AWS. Luck you replied right away or I'll be reading and searching the whole night looking for the right one to use.

Hey slickflick, did you do anything else?
I downgraded to 4.1.1 as well and flashed it, and it still doesn't work for me.
I had the same problem as yours. I first downgraded to 4.1.1, flashed the qcn file and reboot, it didn't detect wind. I put back 4.1.2, flashed it again, it didn't detect. In the end I put it into recovery mode, did a reset and reboot, it detected wind. Then everything works!
After I have applied the the ATT_I317_AWSMOD_dumimei.qcn file (provided by sjravi) on my Rogers SGH-I317M, it's only able to connect to the Wind network only 1/10 of the time.
Under "About device->Status", it does appear to be connected to the "Wind Home" network but it fails to establish connection with the mobile network. In fact, when I try to search for network operators, it can't find anything.
I've tried setting the Service Mode to "Automatic" and "WCDMA ALL", but nothing works.
I own a rogers i317m note 2 have had it on rogers since January 2013..
Today I devided to unlock it! (After a years of *****ing about rogers):
-First I downgraded to version 4.1.1
-Then following the guide on this form to get into the menu with the *# what ever command. I unlocked the phone (make sure to wait the 30 seconds and 60 seconds they recommend after clicking the options) then tested it on a bell sim which worked.
-Then I updated back to 4.1.2
-Next I downloaded the qcn file thing off this site for att device changed the usb option in the hidden menu then backed my file up then restored the downloaded qcn as mine and rebooted put in a wind sim had to go under mobile networks let it search for about a minute and it worked.
Been on winds network for about 9hours now with no problems. Sorry for horrible grammar posted this of my phone.. but if anyone here is having issues with there rogers phone on aws network feel free to message me.

did u get it working?? i have the note 2 i317 originally from telus...got it unlocked and then used the forum's tmobile rom and patch the qcn and it worked. i can use it both on mobilicity and wind right now.... mobilicity however has poor reception. when i switched to wind , reception is strong and my battery lasted longer too.. dunno why... just make sure when u patch the qcn, make sure there are 2 ports which u apply one on. that's how i troubleshoot it and didnt need to install anything else
I followed the instructions on unlocking the AWS bands (did it to 2 buddies Note 2 phones, and worked without issue). However, my phone OCCASIONALLY will find Wind, and will only register on main roads.
I have an S4, and it works anywhere without issues (unlocked AWS bands also), but the Note 2 will not register except main roads, and even then has choppy service.
Used the AT&T qcn file that is found on this site. Not sure if there is something I am missing for the Note 2.
Looks like the same issue as nawkwan.

[Q] No Mobile Network - Not Registering on Network

Background: (beginner level 1) I bought an i317 Note 2 online to use in Canada. Came with 4.1.2 so I did the downgrade to 4.1.1...ALJ2 modem and all to use the free unlock method. I followed the method to the letter and I thought it worked.
Problem: it just doesn't register on the network, it just displays a circle with a line through it where the network bars are supposed to be. I've spent hours, honestly, just searching through several threads and have tried almost all methods I came across to put it to stock and somehow get it to work. I've put in my Rogers sim card and even my friend's sim but same result.
So after months of quietly browsing through XDA and finding the solutions, I am forced to call the seasoned pro's to help me. Again, I've flashed the stock 4.1.1 ROM to put it back to stock and even flashed the modem for it separately and still no luck. The only other thing I suspect could be an EFS issue but I don't know if that is the case, or have the know-how to check and resolve if required. Please help.... http://forum.xda-developers.com/images/icons/icon9.gif
Thanks,

First check your imei by doing *#06# could be corrupted imei.

And cheak ur apn
Yes, I checked and made sure that the IMEI matches to both the box and the sticker on the back. Also the APN appears for Rogers when I have the sim inserted and I am able to select it as well.
Having imei showing is a good sign
Use rom from here MA3 for Rogers you can also find correct odin from that thread.

Hopefuly its not efs problem cuz I know if you have efs issue you will get that yellow box with hardware info showing once you turn on the phone. You also mention that imei is still good and showing when you enter *#06# its more on enabling data connection with Rogers network.

Yes, the IMEI shows properly and matches to the sticker on the back. Also the baseband (modem) info also shows up correctly. It just remains in Airplane Mode and everytime I attempt to disable it, the phone pretends to be "processing" but the Airplane Mode option greys out - and the airplane mode remains active. I've spent all weekend on this and still no luck - guys I need help to bring my phone back to life. Earlier today I reflashed the 4.1.1 ALJ2 stock file through ODIN and still no change.
Also can someone point/guide me on how to restore the defaults on Service Mode/Menu - I bought it second hand and not sure if the previous owner made any changes trying to unlock the phone. I just want to revert everything back to stock to end with a working phone. Will flashing a stock ROM fix/revert any changes?
(I'm talking about the Service menu that is access using the *#197328640# used to unlock the phone)
Thanks.
Guys - I reflashed the original QCN (not sure if its proper or corrupted) that I got with the phone which has returned the phone to out of airplane mode but now I'm not catching any signal. I backed it up before proceeding to try with a dumbimei qcn with the aws mode thinking that might fix my problem. I'm really dumbfounded and need help. It's been 4 days now and I'm still without a phone...

Need help with lost unlocked
Hi, I've been trying to read as much as I can to solve my issue but no luck... I'm about to give up but thought someone here might be able to help hopefully!
Here's what happened, I bought an sgh-i317 running on 4.1.1 from someone online the phone worked properly at the time. I purchased an unlocked code from internet put it in everything worked fine. I later found the way to unlocked for free with the *#197.... but I said what the heck its already done... kept on reading got excited and decided to flash 4.1.2 rooted with odin... after that my nightmare began...
First I inserted an ATT sim and got the mm#2 sim not provisioned, then I tried a friends ATT it worked but when he putted back to his iphone he got his phone block so he had to call ATT to make it work again
Whenever I insert a T-Mobile sim or simple mobile I get the phone not allow mm#6
At first I thought the phone has been reported but I called ATT and they say it isn't, then I kept reading and nothing seems to repair this
I even reflashed everything to stock 4.1.1 to try to unlocked it with the *#197... again but it seems to do nothing now
then I found this http://forum.xda-developers.com/showthread.php?t=2045563
where they say that once you are unlocked you shouldn't flash with odin... I guess I messed up...
My imei matches, the phone has not been reported, whenever I insert a foreign sim car I don't get the network lock screen but the phone not allow mm#6 message
I think that somehow when I updated to 4.1.2 with odin... I either lost or damage my unlock
could someone help?
Thanks in advance

sgh-i317 flashing question

Hey everyone need a question answered. I just purchased a used sgh i317 and am planning on unlocking it to use on the tmobile network. I have read and understand the process of using the aws hack to enable att modem to use the tmobile 3g/4g network. I was just wondering if it was possible to flash the factory image ( SGH-T889_TMB_T889UVBMD1_teshxx.zip) for the tmobile note II with odin from this link http://forum.xda-developers.com/showthread.php?t=2102380 . If I did this would this completely put my sgh-i317 as basically a tmobile note 2 with full data and wifi calling.
I have read in the forums that I should always keep the att modem. Is this also true of the kernal too. Or is my plan to completely turn the sgh-i317 in to an t889 possible as stated above. I really appreciate any imput you would have. thanks!
Most people flash tmobile image so they can use the native wifi calling app.
If that's not a concern for you, I would put in the tmobile sim, unlock it, then add the tmobile 4G APN and reboot. If you live in a refarmed region, you will get 4G data with no further steps.

Can't mix modem's. You end up with a bootloop. But most of the time the modem's are separate from most Rom's. But ya might want to do a double check just to make sure. So you don't run into any problems..

I appreciate it! I think I got it. The stock factory image would include the radio (I guess most custom roms do not), kernal, and OS. Since the sgh-i317 is so similar to the t889, I could technically flash the tmobile factory ROM onto the sgh-i317. I would just have to flash the att modem in place of the tmobile modem. Think I am just Going to flash a custom rom with wifi calling and just flash the newest att modem too. After I unlock the AWS and set my APN to Tmobile, I should be good to go! I appreciate your help guys! If I missed something here, please let me know.
Sounds about right. You're essentially good to go with any ROM or kernel from the I317, T889 and N7105. You should be fine as long as you don't mix modems (check the backgrounder in my T889V LTE guide if you feel like it) or flash N7100 stuff (see multiple reports of messed up IMEIs and such).

[Q] Note 2 does not work ATT To T-mobile, wife's iPhone 5 works fine

Hi,
I have note 2 from AT&T at 4.1.1 with I317UCALJ2 and I took t-mobile connection, I can not have mobile hotspot on. Also I get call drops and less 4G connection as compared with my wife's iPhone 5, she is having consistant 4G and mobile hotspot. I called t-mobile they changed my APN settings to fast-t-mobile.com, but it did not work much, then I was reading a forum and I dialed *#2263# and selected WCDMA ALL (when I did that my APN in the settings changed back to epc.tmobile.com). Now I am getting 4G band but still no mobile hotspot.
My phone is unlocked, I unlocked my phone using the key combinations posted in this forum last year. What should I do to make my phone more usable?
Thanks

I tried that, still no luck, should I put any custom ROM? if yes then which one?
No rom yet....
Since you are changing carriers entirely...have you cleaned the device to make sure no bad data is present ??
I would suggest doing a factory reset to clean the device....
Then enter in the T-Mobile APN again and test...
If the process does not help ...a new or different modem may be needed to improve your signal...
All of the steps to do this are in the general and development sections...and you should begin by searching and reading the steps....
Go slowly...until you understand the process...and only then should you attempt any flashing....
We will be here to help....but you need to learn the process if you intend to flash files to this device...
Start in the "everything" thread in the general section....
It covers the basics of root and flash procedure...and how to avoid mistakes that catch several people...
And do not update your device via OTA...
It will give you a Knox bootloader...and that is not good for users...especially new users to flashing...
Read much....learn much...and only then should you flash....g

are you seeing LTE signal? if not, then you are on T mobile's legacy 3g or possibly the reformed 1900 hspa. Since the phone will not get 42mbps hspa, your speed maybe a bit lower due to 21mbps hspa. I am using the phone on t mobile network and do not have issue. i did have the latest att modem. When I was on the 4.1 rome, I did flashed the latest modem before the 4.3 rome.

I unlocked the phone, I also have supersu and triangle away on my phone. I do not remember what all I did. But I am on 4.1.1. If I do a factory reset, will I loose everything meaning unlock etc? Or should I install a modem? If yes then which one?
If you are ready for the 40 mbps hack....here ya go...
If you have a PC and a few minutes....this link will get you on track ...
I use ATT and have never used this method...but many have...and report proper speeds after unlock to TMO...
Good luck...g

factory reset should not change your unlock. The phone should stay as SIM unlocked (if that is what you meant). Once it is sim unlocked, it will stay as unlocked. It should not affect your root either as factory reset (though I am not 100% sure since I have custom rom so cannot remember if stock rom will remove root). Often it is best to stay with the same modem as the rom version. Here is the link to the modem list: http://forum.xda-developers.com/showthread.php?t=1987541
I have the latest one but I am using 4.3 rom. I cannot recall which modem I had when I had 4.1.2 rom so do a bit search, but I think it is the MJ4.

Unlocked i747 - stock rom connects to 2 other carriers - CM12.1 does not

Hello!
I am currently with Telus and have just unlocked my S3 after purchasing the unlock code. If the phone is on the stock Samsung ROM, I can insert a Wind or Rogers SIM and it works fine. However, on the CM-12.1-20150519-NIGHTLY-d2att ROM, it will _not_ connect to any other network. I tried manually searching for network but it fails with a message like Unable to search networks.
I'm not sure why this is happening or how to troubleshoot this. I would prefer to stick with a Lollipop ROM for now.
The CM d2att wikki page does say that since CM11, we should be using the d2lte version for this phone. So should I be installing the d2lte ROM instead?
Thank you

I installed cm-11-20141112-SNAPSHOT-M12-d2lte and unfortunately you were right. I still can't connect to WIND.
I have another fully stock S3 and I ran the Samsung Phone Info app on both to compare. Under the Firmware tab, the PDA version and CSC version is empty on the phone running CM11. Please see screenshots attached which shows this.
Also, I ran the SIM Toolkit app, tapped Manager Services and it gave me a ME returned a temporary error.
Any help would be greatly appreciated to troubleshoot this. To me it does not make any sense that on a unlocked phone, with stock or custom ROM, Telus (this phone was locked to Telus originally) connects just fine. With stock ROM, I can connect to WIND and Rogers but cannot connect to either when running a custom ROM
aaaaaahhhh !!!! @audit13 , hhhhheeeellllpppp !! (please) :what:
"all i can really do , is stay out of my own way and let the will of heaven be done"
The case is missing because there is no carrier customization on a custom rom.
It was my understanding that wind uses aws which the s3 does not natively support although there are hacks to enable these frequencies.
I am not sure how it could connect to wind on a stock rom.

Hello Mr audit13! It's not just that I can't connect to WIND when runnning CM11, I also can't connect to Rogers. Does that still mean there is a frequency issue?
Edit: Looking at WINDs website: (http://www.windmobile.ca/my-wind/faq/devices)
"The WIND Mobile network uses a frequency called AWS, with bands 1700/2100 MHz.(Phones compatible with the U.S. T-Mobile network often work with WIND)"
When you load cm11 or cm12, does your phone show the correct imei?
Which stock rom will connect to wind and Rogers?
Which baseband are you using with cm11 and cm12?
Crazy autocorrect on my iPad changed csc to case
autocorrect OFF. lol. ty for coming to help. :thumbup:
"all i can really do , is stay out of my own way and let the will of heaven be done"
I just did a sanity check. Installed stock ROM and put the WIND SIM in it. It wouldn't connect automatically so I searched for network and it does not show WIND in that list. It only shows WIND Away which is Rogers or Telus I think.
@audit13, you were correct. This phone will not connect to WIND.
I guess I'll just buy a new phone. Nexus 6, here I come!
Anyone in the market for 2 S3's? One is unlocked.
The i747m can connect to wind with a software hack; however, the hack must be applied every time you reboot the phone.
How much for the s3? It's still a great phone.

I see a couple of S3 on sale on Kijiji for 180. Both phones are in pretty good condition. So I am hoping 180 for the unlocked and 160 for the locked one.
Just wanted to let you know that I bought a refurb s3 from koodo for 90 and a refurb note 2 for 180 from koodo. Both come with a 1 year Samsung warranty. They both looked new. You can't find the phones on their website, you need to call the store and ask for stock. I got these phones with no contract, unlocked them via code, and are being used on Rogers and bell.
Oh, hmm. Well, I guess I will try my luck on Kjiji.
Thanks for all your help.
I've checked out kijiji and craigslist and the prices are similar to your asking price. Many people don't know that Koodo sells refurb phones and it was just a matter if luck for me when I got the phones. They weren't even for me! I've been using an old HTC One X from Rogers for the past 8 months
After reading news that Factory Reset leaves most of the data on the phone (research done at Cambridge University), I am very very hesitant to sell my phones now.

That only applies to the ROMs up to 4.3. Why not just flash 4.4.2 a few times, encrypt, decrypt, re-flash? I'm not positive these steps will make it better but it's the only thing I know of.
