GSM Band and WM2003

Hi,
Is there a tool similaire ton GSM Band switch working for WM2003?
I need to change the GSM freqeuncy to 1900 since i need to go in Canada with an European XDA 900/1800.
I know i can do it from the bootloader, but each time i change it i get a full reset of my device, not so great

The bandswitch tool will not make your phone a tri-band phone, it will be 100mhz off frequency when on 1900, but heres the link anyway.

[Q] Does the European Optimus 7 supports WCDMA 850?

I bought an European Optimus 7 and it shows on the box "WCDMA 900/1900/2100, GSM850/900/1800/1900"
There's any way to put this phone to work on 3G WCDMA 850 networks at full speed?
Thanks

I own a Telus version of Optimus 7. My phone has the 900 3G band on it. I will tell you how to check whether your modem supports 850 or not. First, you open up the dialer and enter ##634#. This will install the MFG app, that will be accessible through your app list. The password that it asks is 277634#*#. Now you have access to the manufacturer test/setting menu. Proceed to the Engineer Menu, and then Modem Setting, followed by Band setting. There, you should see all the bands that are available, and WCMDA basically means UTMS or 3G. If you have the 850 band, it should be available in this menu. There are two other things you need to do before gaining access to this band, if available. But in order for me to continue, I need to know which carrier you plan to use this phone on. I am going to assume you want to use this in North America and you have already unlocked it. Let me know, and I shall help you further on making your phone functional for a 3G connection. BTW, I am typing this on my Optimus 7...the keyboard is seriously great, and if it wasn't for the loose buttons, I would have absolutely no regret over my purchase.

Thanks.
I saw here, there are these options available:
1.Automatic
2.WCDMA Only
3.GSM Only
4.WCDMA 850
5.WCDMA 1900
6.WCDMA 2100
7.GSM 850
8.GSM 900
9.GSM 1800
10.GSM 1900
11.WCDMA 900

Sorry for picking up this old thread again but there is no final answer on this.
The point is that I'm having the same problem, I have a european E900 and I can see the WCDMA 850 in the MFG settings. So is this working?
I'm going to Thailand next week and wanted to use True Move 3G which is on 850 Mhz.

Ok, just for the record - I am in Thailand now and the 850Mhz 3G Network from True Move is not working on the European E900.
Hope this helps for those who were looking for this answer.

LG Optimus 7 E900 Unlock 850 Mhz Band?

Hey all,
I just realized the E900 and E900h have the same modem. The problem with the E900 is that the 850Mhz band is locked. Is there any way to unlock the 850 mhz band? I need it for better reception with ATT.

On the e900 in the MFG menu I have the option to select both cmda and gsm 850mhz band.
I did load the att apn and developer unlock my phone, but I never looked for that band before so you might not need to do those things.

I just developer unlocked my phone. However the 850 Mhz WCDMA band is still locked. Can you receive WCDMA 850?
I'm wondering if one can flash an lg e900 with an e900h rom. By doing this, will this enable the 850Mhz band?
Thanks

Can I flash an E900H rom onto an E900?

I don't know about flashing the e900 rom, I have the stock vodophone rom updated to mango.
and I have 850, 1900 and 2100 bands displayed in my engineering menu > modem options > band selections. Not sure what to tell you.

@Etaduck
Yes I have the 850mhz WCDMA option in MFG. However it is not picking up an actual 850 WCDMA signal. Is your phone picking up 850 for 3g?

I select 850 wcdma restart and get 3g / h depending on where I'm located, but I usually just leave it on wmda automatic
I'm not sure if there is any other way to test what band I'm using, but I'm assuming that selecting it from the MFG menu would be using the 850 band.

can you tell me the exact configuration of your phone? Did you use MFG or Network setup? I desperately need the band as 3g in my area is 850.

AFAIK mobile devices need different communication hardware to physically access some frequencies.
Whilst there may be a software switch to activate access to a frequency.. that does not mean that the unit will contain the hardware to do so.
If I am wrong on this I would appreciate advice.
EDIT: More on this topic and an aswer similar to above here...

E900 and E900h have different hardware conf, most likely different flash ic so its not recomended to cross flash it.

[Q] How to unlock the default wcdma bands of LG G2-D803

Hello !
I m using LG G2 Model D803.
I try to connect 3G but i could not.
I checked and i am in 3G zone, my APN is correct as per Mobile service provider.
After alot of searching on internet and reading threads and blogs,
i came to know about 3845#*803#, from where i went into hidden menu --> WCDMA only --> Modem Settings --> Network Mode.
And i found that the default band of WCDMA is 850 Mhz, while the service provider here in my region have WCDMA band of 2100 Mhz.
Therefore i want to know how to change the default band of WCDMA from 850 Mhz to 2100 Mhz.
Another thing, which i am not sure about is when i select only WCDMA or HSPA, my mobile signals gone (zero) !!!
Is this the reason of having the default WCDMA at 850 Mhz and service provider is providing 2100 Mhz.
I am really confused.
Please help me !!!
I have attached the screen shot of hidden setting where the WCDMA is 850 Mhz.

still waiting for reply ?
