It's odd I done a esn check on a few sites and they all report back that it had a clean esn but the seller said it has a bad esn... Guess the only way to know for sure is to take it to or call AT&T themselves. Hopefully it it's clean!
[AT&T Samsung Galaxy Note II] Product F(RED):
I just had the opposite situation with a T-Mobile Note 2 I bought. Returned that one to seller. Now I have a good T-Mobile Note 2 and I'm gonna sell my AT&T one. I'll miss being able to use my wireless charger, but I hate that AT&T disabled AWS and put a RAT lock on their modem. I know it's a dumb tradeoff (software for hardware) but for me it's a matter of principle. I bought the phone. It's mine. I don't want a carrier I'm not even using controlling it.

By the way Bad ESN could mean unpaid bill or ETF on a subsidized phone. He could be planning to not pay his ETF, making it bad in the future.

Isnt there a fix for that by enabling these hidden ones in this thread? I got it for the wireless charging and cause rn it's a lot cheaper than getting the T-Mobile version oddly somehow...

That could be but I wonder if I could take control of it somehow, I might just get a AT&T microsim and pop it in to see what it does, then if I'm able to take control of the account or somehow get it released to me try to keep half assed using AT&T as lil as possible just to have insurance on the phone just in case it gets stolen again but he'll this one might as well be padlocked to my waist. haha!
[AT&T Samsung Galaxy Note II] Product F(RED):
Well I know putting on CDMA networks when you put a phone on your account, it can't be (as far as I know) blacklisted for nonpayment by the previous owner. Not sure how it works on GSM networks. But if they bought it at contract pricing, they don't really own it yet until they pay it off.

[AT&T Samsung Galaxy Note II] DorkyDev:
What's got me curious is this is a cellphone company and reseller that owns their ebay store whom I bought it from, I believe they're also the ones who refurbished the phone. So I'm left to wonder if when they checked the esn it was about to be blacklisted and then later on the owner of the phone got it all taken care of and this could be why it's not showing up as blacklisted anymore or if they just accidentally sent me the wrong phone and thought they sent me the blacklisted one but indeed sent me a good one actually or if they just didn't know what they were doing to check the esn.

How to write nv settings in text format to phone using QXDM/QPST NV Browser

:confused::mad:

Hi Guys,

This is a very intresting thread and I'm also trying to enable AWS on my ATT note 2. I have spent last 7 hours searching and trying various things to update the nv settings for the radio. Now I have broken down and feel a need to ask.

I made several backups of NV using NV_items reader / writer and QXDM / QPST. I tried to compare my nv file to the one that manni'k's have posted to see what changes i need to make. I understand that I have to add my own IMEI number on line 550 which is not a problem. So after adding that line to manni'k's file i tried to write the text file using N-items reader-writer v1.0 using option write, but as many of you have stated that it does not work.

So basiclly now I'm stuck at how to write that TEXT file format using the QXDM/QPST as it uses are different file extension to make a backup file and uses that to restore. Can someone please highligt the missing link how you guys able to write the NV file from manni'k's post to your phone and enable the AWS.

Thanks

You need to enable those missing nv's before restoring the text file. You cannot just restore that text file. Read the OP method 2

just run qxdm, find the line listed above and click write it will enable the parameter. once your done enabling all of them just restore from the file provided by the op after changing the 01877
[AT&T Samsung Galaxy Note II] TEKHD:
Okay, listen, what you need to do is just get a copy of an NV backup of the T889 (someone you might know with a TMo Note 2) Restore it on your I317 and Done... Easiest, secure, and fastest way... The same thing applies the other way around...

I have both phones, so for me it was a piece of cake. Certainly can't post my file here for obvious reasons...

Another thing... This is completely reversible... You can flash the T-Mobile modem to the phone (I317)... That will screwup the phone and you might get into bootloops... Then go to recovey and reflash stock AT&T modem and you are back to stock NV's and phone will be back to regular Stock AT&T just like any other AT&T Note 2.

[AT&T Samsung Galaxy Note II] Product F(RED):
Not sure but I would contact them to straighten it out. And as far as your comment about wireless charging goes, yeah it sucks but like I said I prefer having AWS on all the time and being able to turn off LTE if I want. I don't like shackles. Screw AT&T. I bought the AT&T one for the same reason originally, mainly the price. But this T-Mobile one was $450 with a bunch of accessories.

[AT&T Samsung Galaxy Note II] Product F(RED):
You'd have to get a QCN backup of the T-Mobile version, strip out the IMEI, and then restore it on the AT&T version to see if it works. Always make a backup of your own, of course, in case it doesn't work.
[AT&T Samsung Galaxy Note II] DorkyDev:
Well yup it really does have a clean esn, I had a Go!Phone account active I went up to AT&T and told them I needed a microSIM and they asked what kinda phone I have so I showed them my normal old flip phone and told them I had the sim card adapter and wanted a microSIM cause I was about to upgrade and I'd be swapping it in and out a lot so they took my name and number and activated the sim card and gave it to me, then later on I popped it in my Note 2 and everything works okay it...

Ok, so I've done this mod. However now I'm looking to update my modem to the latest to see if it fixes the spotty signal coverage I have in my apartment. Downside is I don't have a pc available to me so, is there anyway to reenable the 1700 band after modem update without a pc available?
[AT&T Samsung Galaxy Note II] van131:
I need to update my tmobile modem. How do I do it?
[AT&T Samsung Galaxy Note II] Product F(RED):
No, sorry. The settings required to enable 1700 MHz are inaccessible from the phone itself, which is why you have to flash the QCN backup file.

Go to the T-Mobile Note II section of the site, find the modem thread, download the latest modem zip file, put it on your phone and flash it in recovery. Wipe cache and dalvik cache.

IF You're on an AT&T i317 Note 2, you can't update to a T-Mobile Modem... Well wait actually, you can if ya wanna brick your device. But if ya want the best reception for T-Mobile, then like I said a few posts ago, flash a AT&T i317 Note 2 rom that doesn't have any Modems in it.
[AT&T Samsung Galaxy Note II] Product F(RED):
I thought the person was on a T-Mobile Note 2. But anyways, I've done what you're talking about. All that happens is the phone loads with no signal, and Baseband and IMEI show up as "Unknown" until you flash back the AT&T modem. Oh and the phone reboots.

I used the modem debug code on the T-Mobile Note 2, and realized how many items AT&T had Samsung strip out. Simple things like being able to lock the frequency to any one you want, to being able to turn off LTE (no RAT lock):

If I want to update my modem should I revert my saved QCN then flash the newer modem or just flash the new modem and then reflash the hacked QCN? Or is there no real benefit ?
[AT&T Samsung Galaxy Note II] Product F(RED):
All the hacked QCN file does is turn on the internal setting for 1700 MHz. The reason you always have to reflash it when you reflash any modem, is because the AT&T modems turn it back off. So you would flash whatever modem you want and then reflash the QCN.

So I updated my modem to the latest, it's a godsend for me since was 3 versions back. I have no way to do this mod again at this time but currently with 2 bar connection I'm still pushing 17563 kb's (17.5 mbs) so for now I'm reasonably content. (Before modem update coverage was 3g 2-4 mb's)

[AT&T Samsung Galaxy Note II] wickity:
Ok so to clarify. The QCN flash/mod won't mess the imei or serial number etc. Just enable aws bands correct?
[AT&T Samsung Galaxy Note II] inspron:
That is correct. I have done this many times.
[AT&T Samsung Galaxy Note II] Product F(RED):
The IMEI # is stripped out for that reason; so yours isn't written with the one that was originally in the backup. In other words, this backup has no IMEI in it.
[AT&T Samsung Galaxy Note II] sonny21:
Someone could correct me, but even if they didn't strip the imei, it wouldn't override your current device one.

I think he removed it just for privacy /etc.
[AT&T Samsung Galaxy Note II] Product F(RED):
It would overwrite. The logic is that before you apply this QCN backup, you're asked to make your own backup.

Sent from my Galaxy Note 2
[AT&T Samsung Galaxy Note II] sjravi:
Imei cannot be overwritten by just flasing the qcn file. The qcn file in the thread has an imei but has been changed for privacy :)
[AT&T Samsung Galaxy Note II] Product F(RED):
In general, a QCN file

WILL

overwrite an IMEI if it has one contained within it,

but the one for this mod does NOT have one in it.

That's it.
[AT&T Samsung Galaxy Note II] sonny21:
That's why I am confused, two opposite opinions . I believe sjravi is correct though, cause the file still technically has an imei, just wrong one. No?

It's easy to test, sjravi have tested this yourself btw?
[AT&T Samsung Galaxy Note II] Product F(RED):
What I said is correct... I know because that's how you back up your IMEI on the US/Canadian Galaxy S3 and Note 2. Unlike the non-LTE versions, they don't use an EFS file to hold the IMEI. You use QPST to make a backup QCN which contains your IMEI and internal modem settings. The QCN you're told to download in this thread is someone else's backup, but they took out the IMEI so it doesn't overwrite yours (and obviously for privacy reasons).
[AT&T Samsung Galaxy Note II] sjravi:
This mod was developed by me, so I guess I know this qcn file better :D

It has an imei but is not a valid one. Rest assured your imei will not change even if you flash a qcn file with valid imei.

FYI, I have flashed multiple qcn files from other devices with valid imei on my device.

Also the qcn file in the post is from my device:)
[AT&T Samsung Galaxy Note II] Product F(RED):
Exactly; it's been zero'd out so that it doesn't overwrite your current one. But in general, an unmodified QCN file from another Note 2 CAN overwrite your own device if you restore it on anything other than the one it came from. That's what I'm saying.
[AT&T Samsung Galaxy Note II] sjravi:
Zero'd?? I disagree, its not zero for sure;)

And by the way 0 is also a valid value :D
[AT&T Samsung Galaxy Note II] Product F(RED):
When I open it up with an IMEI editor, it shows up as a string of 0's. That's why I said that.
[AT&T Samsung Galaxy Note II] sonny21:
He has personally tried different qcn backups which contain valid imei in which case it did not overwrite it to new device.

So while qcn backup may hold imei, it will not overwrite a present one via restore.

Got that right sjravi?

Got another question. Qxdm couldn't install for me, I wanted to know how to manually edit an imei contained with qnc backup.

I downloaded HxD which I guess is hex editor and etc, opened qcn backup and found the imei in two locations.

Line 00001700 and 0001bf10, wondering if easier /more effective way to edit imei from qcn backup without Qxdm?

Thanks.
[AT&T Samsung Galaxy Note II] sjravi:
Yes you got it right.

I used hex editor to change the imei. Qxdm did not change the imei for me.
[AT&T Samsung Galaxy Note II] sonny21:
Was it at the same lines for you for imei that I listed? I found one part weird, using my own qcn backup, I found the imei in both those locations. However checking the file you uploaded, the first location was 01 which is fine but then second one was 00. So I am wondering, did you change the imei on one line or more?
[AT&T Samsung Galaxy Note II] sjravi:
Sonny21, I did change imei at 2 locations and both to 01's. May be the location on my qcn is different
[AT&T Samsung Galaxy Note II] sonny21:
Yeah it could be, but the first location was right. Yet the 2nd one on your file was 00 instead of 01. Anyways, which hex editor are you using?

How do you personally find the imei of a qcn that's not yours, search for 08 hex value?

Thanks.

[AT&T Samsung Galaxy Note II] Poke_N_PDA:
so I did this mod several months back. It's been nice, but I've often wondered about my performance. It seems pretty poor. Both in network data and in wifi data. When I do speed test for my wifi, it is ALWAYS Much poorer than my computers. Also, I can hardly ever get any data to work on edge. I've wondered if I should try just blowing everything away and starting over. Has anything been updated For this thread?

Also, if I wanted to start over, my understanding is that a restore to stock would wipe my radio and undo this change but would not cause me to loose my carrier unlock. Is this correct?
[AT&T Samsung Galaxy Note II] inspron:
Your problem isn't this AWS mod. I also have experienced what you are describing.

There are two reasons for your i317 slow connectivity performance:

1) You must update your modem to the latest version i317UCAMC3. The throughput has significantly improved since prior versions but more importantly, the connection stability has been improved.

2) Network performance in your neighborhood, there is not much you can do about this.
[AT&T Samsung Galaxy Note II] REAVER117:
Yes, I would recommend restoring your backed up QCN file before flashing a modem, as I don't think you need to flash the entire ROM. Also WiFi speeds should not be affected at all by this mod, your laptop likely just has a better antenna/wireless card.
[AT&T Samsung Galaxy Note II] Poke_N_PDA:
Thanks a lot for your help guys. So from what I'm hearing, this is what I should do.

1. Restore my backup QCN file to my phone.

2. Flash the new modem. I'm thinking I'll do this by just flashing the most recent stock build for the phone in ODIN as it should include all the most recent firmware for everything else.

3. Re-flash the AWS mod QCN file per the directions on the first post.

4. Flash the ROM of my choice and enjoy. :)

Does that all sound correct? Also, I checked this thread and the most recent modem it showed was i317UCALJ2. Is that just old? Also, what is the most recent Stock build?
