[q] a way to only run edge and no 3g

Hi, sorry for the seemingly noob question, i've done some searching online but have been unable to find out anything concrete. Is there any way to turn off 3g, and just use edge? Alot of the times i just need email or rss, don't need any crazy fast internet...
thanks in advance!

Settings->Wireless and Network->Mobile networks->Network mode -> GSM

Settings- wireless and network(the topmost) -mobile network (second to last) -network mode-then tick just gsm
Sorry my sgs is german so i had to translate the steps but i hope u know where to look

Thanks alot both of you! really appreciate it!

hi there, thanks again for the help last time, however it seems, now that i have enabled gsm, i can no longer enable 3g..
my only options when i look at network mode are:
gsm/wcdma (auto mode), gsm only, and wcdma only, these are the same as the options i had before, so i don't know why it doesn't connect to 3g now

what firmware are you running? have you updated to something other than a stock Bell ROM? there have been issues with some non-North American-based firmware with enabling the 850MHz band.

im running jpx?
it's darky's 6.0 rom, the weirdest thing is it was working prior to me switching to gsm only
should i just flash back to a bell rom? if so... which rom do you recommend? the eclair or froyo? thanks!

I am running froyo, but I have found that if you are running a non-Bell modem, then using the
Settings > Wireless > Mobile Networks > Network Mode
option to switch between 2G/3G doesn't enable the 850MHz band for 3G.
Recently I have flashed the Bell JK4 modem and don't have this issue any more (but strangely now the 900MHz band doesn't get enabled, but I don't need it here so I'm fine with it).
To check for yourself, assuming you don't have SGS Tools (which you should get if you don't) go into the phone dialer, and dial:
*#2263#
This brings up the band selection option. Then go into
[4] COMBI BANDS
and select
[8] WCDMA 850 ......
Then just back button out of there. You may have to cycle your radio by going into and then out of airplane mode to see the effect faster. Let me know if you then have 3G again.

[Q] *#*#4636#*#* settings

Hi All,
I've been messing around with my phone and accessed the *#*#4636#*#* settings thru the dialer. Any one know what the following does?
Testing-->Phone Information
Scroll about half way down there's a popup menu that lets you select a whole bunch of different network types. ie WCDMA, GSM, CDMA, etc.
Does this mean if I take my Sprint phone to Europe or Asian I could use their networks without flashing a new radio?
Thanks,
Ken

This code is used for accessing Service menu of your device.
And you cant use different networks without flashing radio

Even flashing a new radio wont get you new frequencies it seems...

What the network type selection allows you to do it turn off network grades (ie, 2G/3G/LTE)
For example, I turned off my LTE as I don't need that speed and the coverage is spotty. So, in doing so I end up saving battery life bc my phone will only search for 2G/3G networks and wont flip btwn 3G and LTE all the time.
If you want to use your phone on a different carrier in a different country, you'll need to have your SIM unlocked and possibly have flashed the radios required. This should be all there is too it, but I could be wrong.
As it is, if your phone is not the dev. version, your phone will be locked to Sprint, so your phone will not connect to networks that are not Sprint.

Please help I'm in same situation and have no service issue after messing with that setting menu, i have mobilink jazz sim card and xt1526 sprint

LTE on M7 U

I have M7 U (no LTE support) I want to get LTE support on it and this what I have done so far
1. ulocked bootloader
2. s-off
3. changed CID to HTC__001
4. changed MID to PN0710000
5. flashed RUU (RUU_M7_UL_JB_50_HTC_Europe_1.28.401.7_Radio_4A.13. 3231.27_10.31.1131.05_release_310878_signed.exe) from this collection
Now (theoretically speaking) my LTE sholud be working right? it is not
(NOTE: neither my SIM or my area has support for LTE but I'm assuming that if I force my mobile to connect to LTE network there will be no bars in the phone and it will not connect to any network 2G,3G or 4G I have tried that with "LTE onoff" app but it did not work)
if my assumption is wrong, please tell me (I will contact my operator to get LTE support on my SIM and will find an area that has LTE network)
if there is something wrong I've done above, please correct me
if there is something missing I should have done but did not, please point it out
Thank you for the great help you provided to me

I believe the U is actually hardware limited to not be LTE-enabled.

I thought that the snapdragon 600 already has LTE modem but if you are talking about frequencies I do not know about it
there is an article about it but I cannot post it because I have less than 10 posts you can find it in Android Revolution HD page (it is 3 months old)

The S600 does indeed support LTE, but I believe the modems are not integrated into the SoC. That's why the Korean/Chinese version have SD slots. The radio chips are smaller/different than the international one and thus they have space for SD. I could be wrong though.

you could be right, but my purpose of this is to be sure if we can activate the LTE in the U version or not because when I search the internet I do not see a clear answer I just see assumptions with no actual experience and some people are waiting for others to do it to avoid bricking there devices but me I'm taking the risk because I cannot just set there not sure if I can do more with my device or not ( maybe I'm nuts )
BTW if some has any idea on how supposedly activate the LTE on M7 U (even if not sure) I'm willing to try it

Hi,
You can try this , it might or might not work..
I don't have HTC one yet so I don't know what will be the effect, it might brick the device so do it at your own risk.

I Guess last option will be to flash European Radio and try again.

correct me if I'm wrong but I think the European radio is included in the RUU I used (it is mentioned above)

I have seen this post and I got that there is a possibility of activating LTE on my device but still I do not know how.

Hi! Please post a screenshot of the version of the baseband you have in Settings->About phone
After that I'd like to ask if the settings already has the LTE options in mobile data?
If yes then what happens if you select it there?
Do you lose signal?
Does it revert back to GSM or HSPA or whatever?
Does it make your phone crash?

Any update about this?

sorry for being late
in the options there is no (LTE only) option but I have used LTE onoff app to select that option and it reverts back to GSM or auto or whatever, I never lose signal and my phone never crashes
thank you for trying to help
in the attachments you will find two screenshots, one for the base band and one for the network options

I'm trying to revive this thread
so, if anybody has any idea about activating LTE on my phone I would be grateful

Just an idea, but have you tried entering *#*#4636#*#* In the dialer. Then selecting "phone information" then setting manually there?
Not sure if that'll work though still.

I tried to set it on LTE only but It does not work, though the problem is not losing signal bars but it keeps reverting back to the previously selected option.

Even on LTE models the option reverts back when no LTE signal is available
Also I have already confirmed this on a different post months ago that it's not possible.
The HTC One uses 2 different type of power amplifier which controls the frequency signals of the phone and unfortunately the U version's amplifier was not made to recieve LTE frequencies.
Only option to fix this is to physically replace the power amplifier of the device.

is it possible to change the power amplifier for HTC one? you know it has 1/10 rating in IFixit
if it is possible I think I'm welling to try
anyone has a map of HTC one hardware?

HTC m7 - LTE - frequency unlock ?

hello
I have HTC M7_UL model, and trying to connect to LTE network with no luck, is there a way to check or diagnose LTE modem in the phone itself?
LTE discovery app shows 'one bar' on range permanently and no additional information regarding signal, *#*#4636#*#* and switching to LTE also fails
Thanks
-----EDIT---
Case solved, device do not support frequencies served by my operator, it is Sprint version and I need europe freqs, anyobody know if it is possible to turn on all the LTE frequencies in HTC m7 ?? I tried NV but values aren't writable ????
cheers

Question How to lock the Mi11 LTE bands

Hi ,
As I know, the mi11(M2011K2C) only support band28a, but my operater not support that.
I found when the LTE change to band28(LTE 700), the mi11 is swap from LTE to 3G(WCDMA).
May I disable the band? How to do that?
Thanks.

Go to settings- about- all specs- tap the internal memory until it opens the network test page- go to set prefer network type and choose the network types you want to have.

Or by Dial *#*#4636#*#*
Usefull for check connectivity, Dual Sim, IMS, etc...

Hi,
Thanks for the reply.
But in this method, only LTE can be selected, and the band in LTE cannot be selected.

Download activity launcher>phone services>set radio band mode(choose the 2nd one coz there's 2 radio band mode in results).
