[Q] Changing Modem - G3 Q&A, Help & Troubleshooting

Ok, maybe a realy dumb question., but, can we change the frequencies supported by a version of this phone let's say make the D850 support 900Mhz on 3G? I mean by changing the modem or whatever need to be changed, or it's just not a sofware thing and it's set in sillicon forever.

[Q] Changing the frequency of the HTC Desire HD?

Is it possibe to change the frequency that the Desire HD uses?
I just got an HTC Desire HD but it apparently doesn't use the same frequency as my other phone did so I'm stuck on insanely slow EDGE.
I know this request may sound a little odd but I'm desperate to change it.
At the moment the frequency is: HSPA/WCDMA: 900/2100 MHz
And I need to get to: 850/1900MHz
I saw that you can apperently flash "Radios", is this what is needed? What exactly would flashing a Radio do?
If anyone could help me here it would be GREATLY appreciated, I mean what's a smartphone without 3G internet?
Edit: I just realized that both Rogers and the HTC Desire HD share the 1900 frequency, is there any way I could enable the 3G on that frequency?

radio frequencies are "hard coded" into the cpu chipset so cannot be changed...
I dont know if this is what you are after but when youre in telephone mode,
dial *#*#4636#*#*
A menu will come up, choose phone information, then scroll down, you will see "set preferred network type" . There you can change it.
Goodluck

I don't know I'm sorry, hopefully one from the guru's will come and answer your question. In the mean time, why don't you test it...

In "set preferred network type", i choose "WCDMA preferred" already.
You can't change the frequencies!

[Q] Frequency Question

I don't know if this is the right section, if not, can administrator please move it to the right one for me, please.
So I got an unlock Galaxy Note II (T-889V), which works on AWS. I know Telus / Bell / Rogers got a different frequency, but if i want to use my phone on their network instead, would it be a software issue or hardware issue to change the frequency? e.g. will adding their modem file work?
Thanks

[Q] mod SGH-T999 to work on 900mhz 3G

I'm new on this forum and maybe the question I'm gonna make was discussed before, but I wanna know if I flash my T-mobile T999 with another compatible OS version mod, it will get the 900mhz frequency in order to make it work on another country that use that freq or if is the hardware of this device does not support this.
It should work without making any changes to the OS as long as it is sim unlocked.
not work for 3G only EDGE

It works for voice calls (GSM) but on Data only EDGE not 3G.
Are you sure there is 3g on that frequency? If yes, then try APN settings or try to force HSPA only for data.

[Q] D851 LTE europe doesn't work

hello every one.
My lte doesn't work. I already test with the rom paranoid and CM.
I m from morocco our 4g is new and i think is the same as the europe 4g (lte).
Do you have any idea ?
Pls help
Thank you for your time
up
Help pls i need to flash modem ?
Which carrier are you using in Europe? Are you roaming from T-Mobile or have you purchased a different service/SIM card in Europe?
Also, what country are you in specifically?
There was a guide somewhere on XDA regarding Qualcomm processors and band unlocking using QXDM (LTE) and QPST (GSM/WCDMA) though I forget the exact name. I believe there was also concern that it could damage antennas. Also I have no idea if it actually works and mucking around in the NV RAM space is very risky. I would not advise it.
Is at least the GSM service working? If so, is it really that bad that you need LTE? Personally I would leave it at "oh the gsm works, I'm good". :good:
Depends on the carrier you are using, is your phone unlocked? I would assume that it is since your can receive gsm signal.... Anyways, what you would want to do is check your network's APN and check our phones APN settings and add the 4g/LTE APN settings to your phone manually... Then restart your phone and try again, make sure you select the apn after adding it so you know it's active. Try that. If that doesnt work, then go into your APN settings again and just do (reset apn setings) or something along the lines of that which resets/restores your apn settings back to normal/default.... either one could work, try the first one first ofc!

activate preferred LTE band(s) permanently

I have G710EAW (LG G7+) which has by default active LTE Bands 1,3,5,7,8,28. However I live in Europe and I with my carrier I would benefit from band 20 as well.
What I am doing currently, is via service menu I am activating manually all the bands I need (including band 20) in modem settings. This works perfectly fine, actually I am so used to it I can do it within seconds. Naturally after phone restart all is reverted.
It is a minor inconvenience, hence the question: any idea how to make the setting persistent or any tool that would do it after each reboot?
I would like to avoid installing firmware from other model (if that's even possible, I am layman in this...)

I don't know if Tasker needs root but you may be able to accomplish it with Tasker.
Although it may be a pain to setup i think tasker has a subreddit that you may be able to ask somebody who uses it more than I do

Hi, I'm also looking to buy the EAW version for the dual sim feature. So you confirm the phone has all the LTE bands but some of them are locked by the software installed?
I need a phone dual sim that works in Europe and USA....

Well I do believe Qualcomm Snapdragon is an excellent platform and the build-in modem is capable of all bands. I do have EAW version (I think originally from Hong Kong).
The band selection is not available from OS, but if you dial *#546368#*710# there is a hidden menu where in
Field Test -> Modem Settings -> LTE Band Selection I have these bands available:
1,2,3,4,5,7,8,12,13,17,20,25,28,29,30,38,40
To my limited experience any combination works just fine (I am in central EU). The drawback is that after reboot (or airplane mode) only the default (1,3,5,7,8,28) are on.
Just for the hell of it. I tried on my US phone, can't even access the menu Sucks.

It works for me on the T-Mobile variant you have to use the stock lg dialer and type the code in you cant just copy it in
How do you know this has worked? I toggled on the bands that I need bu there was no 'success' or save prompt and if I exit and re-do the process all the boxes are un-ticked when I navigate to the LTE bands page.

Sorry for late reply.. I'm using stock dialer, and enter in manually, still doesn't work.. Maybe it is a T-mobile code or something.. I'm not use to having a phone were I can't access the hidden menues..
