UPDATE: PLEASE SEE CHN110's SIGNATURE FOR AN AMSS MODIFIED Tmobile MODEM (thanks to hotwir3 and delacrow) WITH UNRESTRICTED RAT ACCESS!
The following method is still the one that works with UCLF6. BUT I WILL MODIFY THOSE AMSS BIN FILES AS HOTWIR3 HAS AND SEE IF THE WORKAROUND CAN BE ELIMINATED!

UPDATE 2: USING THE AMSS FILES FROM THE N7005 ROM WITH UCLF6 MODEM DID NOT WORK...STILL HAVE TO ACCESS
RAT USING THE WORKAROUND.

Is it just me or has anyone else noticed we are not locked out of RAT selection on this base?
I'm on edge now...cool. slow but cool. Have to use a previously known work around but it does work. :good: I would like to see if it works for someone else before I post the method I used, PM me if you have want to know how to set it.

Here is the workaround...as I said it is a previously known process, I just decided to give it a try and it works:

First I suggest you must be on one of the new DXLJ2 based ROMs (never tried any other base, its possible 4.1 kanged and aosp Roms may work also)...heres the dialer method I used, with phone powered on take your SIM card out (pry it up a little to get past the battery), reboot the phone then after startup is complete make sure wifi and airplane mode are turned off, dial:
*#197328640# or (short cut) *#2263#...then follow the menu options: (DEBUG SCREEN/ PHONE CONTROL/ NETWORK CONTROL/ BAND SELECTION/ now here you have several options but to get "edge" choose GSM BAND PREFERENCE/ GSM850) THIS IS IMPORTANT> then press on the phone menu key and press "BACK" make sure you see the asterik in parenthesis next to the option you have chosen...then use the phone menu key to select "end". reinsert SIM then restart phone ( dont pull the battery to insert sim).You will also have to check your APN settings and select "bearer unspecified" at the bottom of APN SETUP. Thats it...its an old workaround from when I used my Captivate and SII primarily. Cant remember where I got it (on here somewhere I'm sure) but I had the method saved as text in a notepad file and came across it yesterday.


Good luck and enjoy.

My bad...that might be a mislabel by me, its just a label but to your point I guess it should read egprs..but it is edge (2.5g) and not 3g or 4g.
This from a google search:
General packet radio service (GPRS) is a packet oriented mobile data .... Such mobiles are considered pseudo-Class A, sometimes referred to as ... EGPRS ( EDGE), 236.8, 59.2 (Class 8, 10 and MCS-9), 4+1 ...
and some further searching...

Thanks chn110 for directing me to the modified UVLG3 modem in his sig that allows RATaccess using dialer method without having to pull sim or reboot. All bands are able to be changed...awesome
As for the UCLF6 modem, the workaround in the first post is still applicable.

think this modified modem will allow me to change the band preference (disable LTE) in a cm/aosp build?

I dont see why not, I think it would...not sure but it wouldn't hurt to try. Just have another modem on your sd to flash if it didn't.

Actually this isn't a mod it is a 'workaround' to achieve RAT access on UCLF6. The UVLG3 modem (was modded to carry the amss files from the N7005 base) and does not have restricted access so you wouldn't need to use this method. Although switching bands thru the settings menu is not yet fully functional, you can use the dialer (ussd) code to choose any band...and it basically allows you to switch off LTE and use 3g only. Helps save data when say your near your monthly limit or whenever. As far as the modem from Tmobile goes, basically it probably only is a benefit for ATT users (being unresticted to change RAT selection). It has the 1900 band added so they (Tmobile) could sell the iphone. The speeds when I tested it were unfortunately typical and not impressive.The reason Tmobile bought out Metropcs was to accrue access to their LTE network, so after that becomes final then Tmobile users will finally get the most out of their Notes...be patient it's coming.

Just a quick FYI, I did this selecting only the GSM Band 850 and thought I had hosed my sim/phone. Nothing worked after I did this. I did however go back and select the 850/1900 band and that fixed it. Seems some AT&T area may use both bands.

Were you on UVLG3 when that happened? When you say hosed you mean no cell signal at all? I believe UVLG3 only has 1900 band available for the ATT user. The workaround is for UCLF6 and when something similar happened to me I found that when I changed the last line (bearer) in the APN settings to unspecified that it will work. This is mentioned at the end of the first post. Please let me know as it would be interesting to see which modem you were on when it happened.

I'm on UCLF6, but I'm not on ATT so my Bearer is always set to unspecified

Yeah phone just showed the circle w/ a line through it for the cell signal. So it saw the sim card, but the radio wouldn't attach to just the 850 frequency. If I remember correctly, I believe that AT&T uses two frequencies. One for uplink, the other for downlink, which is why it started working after I picked the 850/1900 line.
