Nailed it!!!!!!!!! My 4g is back again

demension21 · Feb 13, 2013

Last week, I did the most stupid thing on my note 2 (SGH-t889). I saw a rom that i liked for the n7100 and flashed on my 889v. Of course, rom works fine but no DATA OR VOICE :crying:crying:

So I flashed my phone with my previous rom and I had data again. All of a sudden, after installing all my apps, I lost the connection. My phone went completely crazy
i saw unknown baseband on settings / phone status; phone rebooted itself. I tried to flash a stock rom, or even flash the 889v modem on any rom and no luck; i was on a constant boot loop

I had to flash another modem from T-Mobile to get out of boot looping (MODEM: T889UVALL4_Modem-Jan_16_13-teshxx) but i couldn't get on any network even if I my phone could detect them (I'm on Videotron).

I've searched xda and other sitEs for solution on how to fix an almost empty esf folder. On a tmo modem my emei was 0 0 and on videotron modem it was null.

SOLUTION

My efs folder was almost empty; no nv_data.bin and those other files.

I went across this site

http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-enable-t-mobile-3g4g-aws-bands-on-att-galaxy-note-2-sgh-i317/

It's a tutorial on how to enable aws on the AT&T note 2. It had just what i needed: a qcn file. Ive follwed the directions on the site; flashed the qcn file with the QPST software and rebooted the phone. My emei was a bunch of 0. No signal still but the battle wasn't loss.

I've used the EMEI NVitem generator to create en encrypted file of my EMEI
Put it on the the NV reader / writer, reboted the phone

And VOILA!!!!!!!!!!!!!

i got my signal back but with a tmo modem (MODEM: T889UVALL4_Modem-Jan_16_13-teshxx)
my 4g is back and my gps is working flawwless

Now, just to let you know, I'm not a developer and i take no credit for this. Even if this thread get approved or deleted, I just wanted to help other members like me who are stuck on the same situation (especially 889v owners). At the end.... MY PHONE IS BACK !!!!!!!!!!!!!!!!!!!!!!!

ohhhh! i allmost forgot....

I AM NOT RESPONSIBLE FOR YOUR PHONE

Problem was I used serveral tools to try to fix this and they did not not requirer the check digit at the end of the imei. The CDWS imei converter requires it. I'm back up and running !!!

Wow. I followed your steps to the letter and it worked, thank you so much!!

Have you flashed back to a VTR modem or would that mess everything up? Thanks again for your help.

From past experience flashing the videotron modem would bring me back to boot loop, wouldnt lose imei or signal but would start then after 30secs reboot.. Im stuck with tmo modem. Works fine but signal seems a little weaker.

i have canadian note2 t889v that i got from craigs the other day. everything seemed fine, didnt have sim to try for mobilicity that im on (aws band), he said he used it with rogers fine
I put the sim card, went to search networks but my provider was not listed there. So I rooted the phone , loaded twrp, flashed prerooted factory rom for t889v ( from mrrobins) , no network, than i flashed original factory rom, still no luck, than i flashed t889v modem and still the same.
My imei is present, and matches one on back of the phone. My efs folder is there and is populated (dont know if anything is missing from there)
I dont have backup of efs or imei. What are the chances it is corrupted ? Does anyone have any suggestion, and should i try this method to try to fix it ?

You may have to put your apn settings manually for your carrier. I would try that to start.

Have you check the *#2263# menu to make sure it is on the correct band, also in network setting you can switch to gsm, wcdma, so on. As for imei as far as I know if it were corrupt your imei would be bad. Is it possible the phone has been blacklisted?

knnrsk · Apr 24, 2013

That code dont work in stock dialer. And mobilicity dont block imei #
