This post should really be a reply to the development thread found here:

However, due to my lack of post count, I can't post it there.
In any case, I just wanted to say thank you to the OP. Utilizing the information in that thread and a few others, I was able to get my G2X to recognize 850 MHz UTMS providers. Although I haven't yet had a chance to test the data on these bands due to my current provider not having roaming agreements with them, it seems that being able to see the UTMS network may be a step forward.
Hopefully, I will have a chance to test further tomorrow and verify that the 1900 MHz UTMS band is also working properly.
If these tests prove successful, I will post details on how to enable these bands.
That's awesome, man! Hopefully it works when you test it tomorrow. Good luck

I am the OP of the thread you referred to, the one about the Qualcomm modem commands. I am very pleased that you were able to use that information to achieve the enabling of other cell radio bands which the modem is capable of but were not available for use. I tried too and was partially successful but not to the point of enabling the recognition of cell service providers which operate on those other bands. I hope that you have succeeded in achieving full operation of the 850 and 1900 MHz UMTS bands which will enable owners of the G2X/P999 phones to connect to networks which use those bands. I am looking forward to your next post.

If I am understanding correctly, this would allow G2x phones to work with the new T-Mobile LTE 1900 Mhz signal, correct? Or am I way off base?
I believe it's AT&t's networks

Unfortunately, as suggested by Core Memory above, I have not been completely successful in this investigation; however, I will post what I discovered along the way for the benefit of others. Perhaps someone else can pickup where I left off and get things working.
First, a summary of the final status:
1) Updated NV Items to enable 850 MHz and 1900 MHz bands
2) Was able to see 850 MHz UMTS providers under the "Search Available Networks"
3) It appeared that a connection was being made to the UMTS provider based upon both the signal strength monitor in "About phone" and the Engineering Mode page that provides data regarding 3g connections
4) In the Engineering Mode page, it seemed that the device was trying to connect (login?) to the network but was not being successful with the login
5) When at the lock screen and forcing the connection to the 850 MHz UMTS network, the "Emergency Only" text appears further suggesting that the connection is working but that my configuration for the network may be wrong.
6) No 1900 MHz providers ever appeared in the network lists while searching. I am not sure whether this is because this band was not functioning or if it was because no such provider existed since I am not terribly familiar with the coverage where I am currently at.
For those who wish to follow this path and test in their own local markets, please see the following steps required to reach this point:
Tools needed:
1) QPST 2.7 (Build 366 or later)
2) QXDM 3.12.714 (or later)
Steps:
1) Install necessary tools on your computer.
2) Enable USB debugging (Settings-->Applications-->Development)
3) Connect phone to PC
4) In the hidden menu (1809#*999#), ensure that Port Setting is configured to CP USB.
5) Launch QPST Configuration
6) Under Ports, select Add New Port.
7) Locate your device and enable the port. (NOTE: There may be two ports available to you here. I believe that you want to use the one that is for Serial / USB/QC connections.
8) From QPST Configuration, launch the "Software Download" tool under the "Start Clients" heading.
9) From here, create a backup QCN file. This backup may or may not enable you to recover from making a mistake later. Also, there is alot of information in this file if you care to navigate through it.
10) Launch QXDM Professional.
11) View-->New-->Common-->NV Browser
12) Options-->Communications-->Target Port (Select your phone)
13) The previous step should have "enabled" the NV Browser lower pane
14) Read and record the following NV Items
a) (441) Band Class Preference (0xFFFF)
b) (946) Expand Band Preference 16 to 32 Bits (0xBFFF)
c) (2954) Bits 32 to 63 of Band Pref (0xFFFFFFFF)
d) (1877) RF Band Configuration (0x0000000002680380)
15) Update item 1877 per discussion below
16) Reboot phone
17) It may be necessary to configure the Modem Setting in the hidden menu to reflect the additional bands.
NV Item configuration discussion:
I am no mobile phone programming expert (< 4 hours playing with them at this level to date); however, as near as I can tell, item 1877 configures the hardware of the modem while items 441, 946, and 2954 appear to be some type of masking bits regarding what bands to prefer. As such, I believe that the original value of item 1877 enables the following RF bands:
(Bit:7) GSM (1800)
(Bit:8) GSM Extended GSM (E-GSM)
(Bit:9) GSM Primary GSM (P-GSM)
(Bit:19) GSM (850)
(Bit:21) GSM (1900)
(Bit:22) WCDMA Band I (2100)
(Bit:25) WCDMA Band IV (1700)
If you set 1877 to 0x000000006E80380, it should enable the following:
(Bit:7) GSM (1800)
(Bit:8) GSM Extended GSM (E-GSM)
(Bit:9) GSM Primary GSM (P-GSM)
(Bit:19) GSM (850)
(Bit:21) GSM (1900)
(Bit:22) WCDMA Band I (2100)
(Bit:23) WCDMA Band II (1900)
(Bit:25) WCDMA Band IV (1700)
(Bit:26) WCDMA Band V (850)
If anyone succeeds in getting any further using this information, I would be very curious to hear of your success. Also, please do share with the community such that we can collectively move forward.
Disclaimer: I accept no responsibility for any damage that you may cause to your phone with these tools or procedures. Please note that these tools give you fairly low-level access to your system that enable you to significantly mess things up. Further, please note that modifying the radio bands on this device may void your warranty and/or be in violation of local regulations as set by your local authority (e.g., the FCC).

You've made a lot of progress, your information is very useful. I'll use it for further exploration.
Did you test it with a SIM card with a data plan which uses those bands?
Do you know how to use QPST and/or QXDM flash the phone with a binary file for the baseband?
I did try to connect using sim cards with data plans on the specified frequencies.
As for flashing a baseband, it seems that you should be able to do so with these tools; however, I didn't look into it.

The following was done while my phone is using the WIND SIM card which is my carrier and is restricted to AWS (WCDMA 1700) and Network Mode is set to WCDMA only.
I used your instructions to enable the UMTS 850 and 1900 MHz bands. One clarification is necessary. The HexaDecimal number 0x6e80380 = Decimal number 115868544 = Binary number 0b110111010000000001110000000.
The binary number is read from right to left with the first binary bit on the extreme right designated as bit 0 of the 27 bit sequence. The binary number is the key to the hexadecimal number used to program the RF Band Configuration in QXDM. For example, according to Jwells777, bit 23 is set to binary 1 to enable WCDMA Band II (band 2) and bit 26 is set to binary 1 to enable WCDMA band V (band 5). Refer to Jwells777 post in this thread which states the binary bits used to set the phone to use the phone's bands. Here's a binary-decimal-hexadecimal converter: http://www.mathsisfun.com/binary-decimal-hexadecimal-converter.html
The HexaDecimal number 0x000000006E80380 can be entered directly for setting "RF Band Configuration" at line 1877 in the NV browser. The HexaDecimal number is converted into the decimal number 115868544 which will appear when another read is performed. In Engineering Mode, the SW Enabled Band reading of my phone changed from 0x0000000102400000 to 0x0000000106C0000. When I changed the phone's setting to Automatic Band Selection, the SW EnableBand reading changed to 0x0000000106e80180. Changing the settings for Band Selection and/or Network Mode will change the SW EnableBand reading on page 5 of Engineering Mode.
In Band Selection, I enabled WCDMA 1900 which caused my connection to WIND's AWS 1700 to drop. I Looked at page 5 (RF Calibration) of Engineering Mode to see which bands were activated and found:
WCDMA1 : 22.37, 22.45, 0.00
WCDMA2 : 0.00, 0.00, 0.00
WCDMA4 : 23.47, 23.19, 0.00
WCDMA5 : 0.00, 0.00, 0.00
WCDMA8 : 0.00, 0.00, 0.00
GSM850 : 32.70, 32.63, 0.00
GSM900 : 32.76, 32.71, 0.00
DCS1800 : 29.40, 29.50, 0.00
PCS1900 : 30.10, 29.90, 0.00
LOSS:
-1.06, -1.18, -1.24
-1.54, -1.64, -1.74
-1.80, -1.79, -2.01
-2.11, -2.21
The same readings occur with Band Selection set to Automatic or manually to any other band except AWS which is the UMTS band the phone was set up to use at the factory.
This indicates that WCDMA2, 5, and 8 are not RF calibrated but DCS 1800 and PCS 1900 are RF calibrated.
I also found that
When I do a network search, it finds WIND and Public Mobile which operate on UMTS 1700 (AWS) and Bell and Telus which operate on UMTS 850 and 1900 but not Rogers which also operates on UMTS 850 and 1900. (Rogers does appear if I search for GSM networks too.)
"In Canada, UMTS coverage is being provided on the 850 MHz and 1900 MHz bands on the Rogers and Bell-Telus networks. Bell and Telus share the network. Recently, new providers Wind Mobile, Mobilicity and Videotron have begun operations in the 1700 MHz band."http://en.wikipedia.org/wiki/Universal_Mobile_Telecommunications_System
That indicates it is able to receive signals on UMTS 850 (Band 5) and 1900 (Band 2) which should enable the phone to see TELUS, Bell and Rogers.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
When I select connection to Bell or TELUS, the phone tries to register but fails with the message: "Unable to connect to this network at this time. Please try again later." That message is generated by the phone's firmware/software, not the network.
I haven't yet tested the phone with a SIM Card for Rogers or Bell or TELUS. A friend has a Rogers SIM card with a data plan but I don't think it will be of any use to test the phone's supposed additionally enabled bands.
Conclusions:
Cognitive overload.
I am finding this quite confusing because of the variable terminology used such as UMTS, WCDMA, PCS, DCS, and the various bands and transmit and receive frequencies used for each protocol. If someone could make more sense out of the information I've provided, that would be very helpful.
Questions:
Engineering Mode Page 5 (RF Calibration) indicate that WCDMA Bands 2,5, and 8 are not RF calibrated but DCS 1800 and PCS 1900 are. Does this mean that the phone will not transmit on the WCDMA Bands 2,5 and 8 because the RF calibration for transmitting is not available?
If anyone can add something useful to this thread, that would be greatly appreciated.
nvm sorry mood pls delete this
Glad to hear that someone else was able to see the other bands using the information that I posted.
I would also add that I am able to see att in the US but not connect. I receive the same error mentioned by CoreMemory. If anyone has access to an O2X and could provide the qcn dump, it may help configure any other NV Items related to the new bands that we have missed.

I wonder if the qcn dump from the O2X is useful since it has a different modem, it doesn't have the Qualcomm MDM6600 which is in the G2X/P999.
If we could get a qcn dump from another phone which uses the MDM6600 on the bands we want to get working, that would be a lot of help.
The Qualcomm Mobile Data Modem Software Interface 80-Vr001-2 manual would be very useful too.

I didn't think of the fact that the modems are different. I agree with you that it would probably be more useful to have the dump from a phone with the 6600 that is configured for the new bands

I bought my 1+ from the website and it was working on Wind's network (1700/2100 MHz) until just now. I flashed CM12 nightly and realized I couldn't make phone calls (data and WiFi were fine). So I followed a thread on XDA and changed my band to USA/Europe (*#*#4636#*#*), but none of these have 1700 or 2100 selected. Now, my phone won't detect Wind's network in Settings > Network Operators and data/SMS/voice won't work.
I tried many different modems (CM12, 44S, etc.) but it only shows Bell, Telus, Rogers on the network scan. Any ideas on how to get Wind back?
Update, here's my analysis (this is for CM12 nightly):
In the stock 44S ROM there was an option to choose "Auto" for GSM/UMTS band under the phone testing menu (open Phone, dial *#*#4636#*#*, click Phone Info). Auto lets the phone pick up frequencies that are not specified in the other 2 choices: USA and Europe, such as 1700 MHz and 2100 MHz.
If Europe or USA is chosen for the GSM/UMTS band, there is no way to go back to Auto and the phone is locked out of connecting to networks running on the 1700 and 2100 MHz frequencies, such as Wind Mobile in Canada and other AWS providers. This is urgent and the only way to fix it was to flash back to stock, choose Auto, and reflash later versions. Changing ROMs or modems did not work.
Does anyone else have a similar issue (you can check whether or not you have the Auto option in the testing menu) or is there a way to fix this that I'm oblivious to? I've raised a JIRA to Cyanogenmod.
