i-mate PPC GSM Band

Hey folks,
Is there a utility/hack that allows you to change the GSM band from 900/1800 to just search the 1900 band? Since upping to 1.72 my radio always locks onto the 900 band and stays there for ages before locking onto my operator (on the 1900 band). I have to have at least 80% signal level. I know that 900 generally is a stronger signal (the other operator is always at least 10-20% over my operator), so thats why [note: I cannot roam with the other operator].. I know the new iPaq seems to have a band select, and my Treo 600 does too....
HTC do you have a util?
Any help greatly appreciated.
Art

under my phone settings i can choose network and set pref network and all kind of stuff like that
HTC do you have a util?

i really doubt that HTC hang around this site you i think that
any questions you want to aim at HTC have to be mailed to them

Try this: go to phone, tools, options, network, network selection and put it in Manual, select your network and OK.
Tell us if it works well thus.
If it dont work, you can install old radio version.

Thanks folks for the replies.. That's actually how I have it set now (manual on my operator), but for some reason when you turn the radio on it locks on to the 900 band and just sits there.. If I walk around until a strong enough signal is obtained from my operator it'll lock on; but as you can imagine this is really annoying.
Thanks again for your pointers. If I find anything out I'll let you know, as I've also shot an e-mail to Carrier Devices; and will shoot something directly at HTC.
I may also drop down to Radio 1.10; but I hate having to re-install all my software again..

You can make backup, install old radio version and make restore.

Samsung Omnia i900 - unlocking UMTS frequencies

Hi All,
Currently released version of Samsung Omnia i900 does not support UMTS 850/1900, which are north american 3G frequencies, according to official Samsung documentation, as well as FCC approval docs. However it has been recently established the radio chip does support those frequencies, and they are locked in the firmware only. Here is the evidence to support this claim:
This is the official FCC documentation for i900 certification:
https://fjallfoss.fcc.gov/oetcf/eas...me=N&application_id=476604&fcc_id='A3LSGHI900
On the page 4 of the "Internal Photos" document you can clearly identify the radio chip - it's Qualcomm RTR6285 and according to Qualcomm:
"Support for Eight UMTS Bands, Four EGPRS Bands, Triple-Band Receive Diversity and GPS Integrated into Power-Optimized RTR6285 Device": http://www.qualcomm.com/news/releases/2006/060213_worlds_first_single.html
So, it's only as matter of unlocking those frequencies in the current firmware. Samsung made our job a little easier, by recently making a public release of new ROM with updated firmware, so we won't have to dump it ourselves: http://www.samsungmobile.com/promotion/omnia/sg/sub02_xp.jsp#
I have limited free time and limited experience with reversing PDA firmware, to be able to achieve this by myself - please help.

I just got an Omnia and sometimes it hits the 3g network so i am sure that the firmware is there but it is locked.

more details please - where are you at? what network/carrier do you mean? do you really see 3G icon and experience fast browsing/download? what is the firmware version on your Omnia? (Settings -> System ->Version)

AT&T.I have it from Singapore.PDA:i900DXHH3/DZHH3.As i mentioned it hits 3g for a minute or so and then it goes back to edge

man i sure hope this issue gets fixed!

a US model for the Samsung Omnia is coming to the US in October via AT&T. Look for the Samsung Mirage.

AllTheWay I started this thread to solve the problem for people in US,who already have Singapore/European Omnia, the i900. It's a well known fact Mirage hits AT&T on October 21st, but it doesn't help us one bit. Unless of course, you're willing to dump the ROM from i907, reverse it and replace the i900's radio with the one from i907 with all supported UMTS frequencies unlocked

I wish somebody could help us out on this issue, I dont know enough about rom editing to be of use ;(
besides, i think the 907 is already available but not branded to at&t: http://www.celluloco.com/samsung-i907-omnia-8gb-us-3g-support-version-hsdpa850-1900-e-pr-1873.html

any update of this thread?

HTC Diamond users with US 3G - please help
I'm starting to believe it might actually be possible to tweak existing radio firmware to unlock UMTS 850/1900Mhz bands using already embedded secret debug menu from Samsung developers, rather than having to dump it, reverse it, patch and flash back. Here is the secret code to access Root Debug Menu on Omnia: *#197328640#
Option #4 "UMTS rf nv" has sub-option "umts rf nv write", which I think allows to modify the active UMTS bands in the radio. Assuming we have that set correctly, option #9 "Common" from the same Root Debug Menu has sub-option #5 "WCDMA Set Channel", which allows to specify downlink channel range.
Here is my idea: some devices, such as HTC Diamond with US 3G enabled radio, have the same Qualcomm chip as Omnia, and run the same WM 6.1 OS. So,
I'm thinking it's worth a shot if someone with US enabled HTC Diamond provided us with settings from his device for those 2 configurable menus I just mentioned. If you backup your own settings, so you could restore them if it doesn't work - I think trying settings from another device will not fry the radio, worst case scenario transceiver will just shut down and be offline until settings are restored.

This would be great.... Iv'e been dieing to get 3g in the usa with the omnia.... Can anyone help with this?

Any updates on this? Would be nice. Especially now since we know omnia isn't coming to ATT as i907

If possible i will donate to the guy that dicover how to enable!

It may be easier to copy the setting from an I907 Epix. That has almost identical hardware and it is ATT + Samsung + Tri Band UMTS.
When I try writing the WCDMA channel it says "That value is wrong".
Also, I can only set one number, so I assume that they want me to set one in the listed range which is WCDMA2100.
Here are the bands:
http://en.wikipedia.org/wiki/UMTS_frequency_bands
Oddly, the Channels currently set stretch a few beyond the range cited on Wiki for WCDMA 2100. They start on the same channel.
Another oddity is that there is no uplink channel. I suppose that people just use Edge for this? Does the I907 do HSUPA?

well...
i'm living in ISRAEL,
and we have GSM network but we also have another cellular company that work with "UMTS 2100/850" band..
i'm working well on 3G with the 2100 band (my onmina have only UMTS/WCDMA 2100 only without 850 also..)
i will be happy to open if it's possible the UMTS/WCDMA 850 also.. so i'll have both 2100 + 850 on WCDM/UMTS (not GSM) freq...
but i'm not shure it's possible to open what ever you like.. anyway i'll try to ask our guys (at my cellular company i'm working at) about this freq stuff...
hope this thread will bring us good information..
also, just know.. my job is with Cellular phones.. and we have "for Testing" Omnia phone with WCDMA/UMTS 2100/850 bands..
but i don't know how i can download the firmware to my pc and try to use it on my omnia back...
if anyone know how i can "take-out" the firmware explane to me and i'll try to do it....

Someone else has further evidence:

OK guys,
i had this omnia in my hands..
the Version says
PDA: i900LJJHK1/JJHK1
PHONE: i900LJJHK1
as i think.. it's diffrent model.. I900L this "L" model.. not like ours phones... (i think, it's looks exactly the same!)
i don't think the ROM will chane the bands anyway..
anyway as you asked me to do.. when i'm doing the *#2263# code
i'm getting diffrent menu then our Omnias..
i'm getting 3 options that one of them it's "WCDMA Band Select" and in there you have ALL the UMTS bands and there is "Automatic" option.. what says this phone open to all kind of UMTS networks............ (including GSM also..)

yes, it was suppose to be with "L" mabe i forgot it on Modaco forum
anyway i hope this is only Rom issue... but anyway i can't "Rip" the rom right now.. because this phone is 24/7 testing time and i can't "make it gone" from the test station to drop the rom to my PC
i hope there are more guys who have this I900L to share the rom with us..
anyway you remmeber the code that you can change the phone settings buy country?
the main code is (type it from the dailer) *#1546792*#
and the password for section "2 - Preconfiguration" is *#81230*#
it's looks like if we will have the code for the "Internal" section, mabe we will find something in there ?!?!
if we will change to another country.. like Austrlia or something.. the bands will change also? what you guys think?

Hi juvaknin I was reading on web that this i900L is for latinamerica and its frequency was
Cellularhone
Cellular_Networks: GSM850, GSM900, GSM1800, GSM1900, UMTS850, UMTS1900

Polaris Radio problem solved!!

Hi,
If your polaris having radio problem after flashing with any custom ROM (or even default) and setting the radio to Murata radio, then you can try the following solution.
The problem may include:
- you have strong GSM signal but you cannot make a call ( for example 1 success out of 10 trials)
- you cannot receive any call (dropping call) not on purpose.
- The battery power drains quickly (..few hours till a half day.)
- The GSM signal is not stabile (strong but kept frequently searching again for signal).
I have tried many ways, from flashing to original ROM and set to any Murata radios, but the problem still presists. Then I did the following.
1. Flash the polaris with any original ROM
2. Flash the polaris radio with the latest official radio version ( I just used the one that included with the official rom that I downloaded from http://www.htc.com/www/SupportDownload.aspx?p_id=59&cat=2&dl_id=113)
3. When the phone is ready, go to the setting, the phone, and then the service. From there you will have two questions, then select the first question, and choose GSM instead of auto, leave the second question intact i.e. "auto".
4. Your phone will reset its GSM connection, and then just wait. It will display "G" next to the reception bar. Then you can test by making a call or receiving a call.
5. If you still have problem, try to disable the HSPDA or any 3G services.
In my case I have T-mobile, where in Europe it is claimed to work perfectly. Learning from IPhone 3g problem in US, where Apple and T-Mobile tried to blame each other, and looking back to "poor HTC support" I could suspect that HTC has not provided the (old) Polaris with "the right" 3G driver.
I hope it helps. Let me know.

I'm sorry I do not quite understand here ...flash official ROM and official radio? then what? can I then flash any cooked ROM? or ported radio from other device? Thanks.

i have an official rom 1.40.466.1 WWE with Radio rom 1.58.25.21 and also i had this radio and low signal problem since i got the phone, never had a good signal at home.
tried to set the band in phone settings to GSM as you said not AUTO and it worked like a charm. thanks a lot

Hi Deepthroat,
I just did it with the official ROM, (ROM version 3.13.405.0 WWE, Radio version 1.59.42.15). However, some reactions confirm that it also works for any custom ROM and Murata-radio. Honestly, I have not tried to any other combination, just give it a try on your current configuration.
Thus, you can skip step 1 and step 2. Just minor correction on step 3, you go to Settings, choose Phone, and choose tab Band (not service as previously posted), choose "GSM" on the "Select your network type", and leave "Auto" for the "Select your GSM/UMTS band" and finally OK.
In my case, now I still have my polaris battery fairly full even after one day. Before the battery already dropped to 50% or less in after one day.
Please confirm if it works, you will save a lot of desperate polaris owners....
thanks

I can confirm the band tab change: network type from auto to gsm and gsm/umts to umts 900+1200 + gsm 900+1800 as a solution to battery drain and poor signal related problems as written on the first post.
I'm using gullum's latest rom TF2D III with the latest radio rom 1.59.44.02.
My reception is excellent, GPS works good and battery drain is not dreadful.

About the fact that 3G is letting the battery drain very quickly.
This is not a problem, but it's just the way 3G works. 3G just requires more battery power to function.

It means that we can't use HTC cruise/polaris for video call ??
I bought the polaris at vietnam and then I used it at Indonesia using Telkomsel as carrier. before I have bad signal also after upgraded the rom to the 6.1 it became good reception for GSM connection but when I need to use the 3G/HSDPA connection there is no signal. (using Band selection )
I already upgraded the RADIO to 1.59.44.02 and the problem still the same..
could anyone help to give info how to activate the 3g connection ?
thx

As I understood, Telkomsel Indonesia has a deal with Siemens to implement 3G/W-CDMA(or popular with UMTS) but not yet HSPDA (http://www.thejakartapost.com/news/...n-contract-set-3gwcdma-network-telkomsel.html). The 3G/ HSPDA allows networks based on UMTS to have higher data transfer speeds and capacity, however not all countries have implemented it (this is commonly termed as 3.5G network). So I guess in that case, you should set the band setting tab, Networktype to "GSM" and Select your GSM/UMTS band to the one suitable to your operator.
The problem with current polaris radio is that it is still not efficient to distinguish GSM and W-CDMA networks that leads to many side-problems (stability, quick battery drain, not working camera and etc). Though, I have not tried, some of friends claimed that polaris can support perfectly video call. So you have to work hard to find the right setting for your net. provider.
goodlucks

Actually I just want to use video call. Oh...very sad to hear that..
so do you think it's the polaris inherent problem that we can't do anything..?
I just try all setting..and I try also other operator like Indosat and proxl and the problem is same.
When I set the Band selection to W-CDMa or auto, sometimes After soft reset, polaris detect the 3G network but in 3 second dismiss and change to GSM network in most of the time just no signal.
everything is ok when I select the GSM only.
so no other option ?
thanks

If I were you, I will do the following:
Telkomsel requireshttp://www.telkomsel.com/web/info_3g, in Indonesian)
1. your phone is 3g (fulfilled by polaris)
2. You have registered to 3g service
3. You are in the area where 3g is supported
4. You have sufficient 3g signal.
In addition, Telkomsel uses 3G / UMTS / WCDMA / 2100 MHz. So if you have met the requirements, just set "GSM" and "GSM+UMTS 2100" in your polaris band tab (phone setting) and don't forget to enable the HSPDA in connection tab. If it does not work, reflash your radio rom to latest official release:1.59.42.15.
If it still does not work try to use 3g service in another supported handset (nokia or ericsson), if it works then it is the time to sell your polaris (just kidding!!!).
goodluck!!

1700 and 2100 wcdma on N7100 intational

So I was playing around with my unlocked note nd I found a selection of bands nd I can select them but not sure yet if it does unable 1700 nd 2100 bands to work on wind mobile or tmobile any ideas ive the pictures

What code did you enter to find those options?

Note 1 had the same menu options.
It doesn't mean anything without actual support in the phone.
I assume, like the Note 1, if you turn those on your phone is going to reject your sim card.

Hi just peeked into this and was able to select 1700 band, go to comi bands and select 1700 wcdma and any other missing band and it will be selected. If it makes any difference i dont know since im in a good refarm area for tmobile.

By the sound of it our hardware just don't have the bands but yet we can select them kinda strange but if you could try using tmobile sim let use know what happens

I was able to do this also, with the leaked XXDLJ2 FW (4.1.2) - I tried with earlier FW before and couldn';t get into the menu - could be total noob error though...
Remove SIM card first.
Then power up Phone, dial #*197328640*
Select: DEBUG/PHONE CONTROL/NETWORK CONTROL/SELECT WCDMA BANDS
from there, it seems you can select ALL, or add the bands you want. (I'm on TMO USA so I selected 1700/1900/2100)
Now, what I don't know is...once you re-insert the SIM ( and you have to power cycle to do that) does the TMO SIM override the changes I just made? I have very weak 4G near my house so I cannot check if 4G is working or not.
CORRECTION: Forget what I said about removing SIM card !!! I was able to access the menu with the SIM inserted, and it looks like my settings are holding ( there's an asterisk next to the WCDMA bands I chose). This is promising!

I did this on a stock rom and after rebooting settings stay the same. Cant tell if itll make any difference since im at work and dont get good coverage. Will report as soon as i can and im on tmobile california

Sadly, it appears that any other setting than Automatic will disable WCDMA altogether - I sat in my car for 20 minutes right under a cell tower tryin to make it work, but was stuck on Edge...as soon as I selected AUTO, my phone jumped to H+ ...and it was on the 1900 Band since the 1700 band is automatically unchecked when switching to Auto. Oh well...gotta wait for the damn TMo refarm then.

The TMUS reframe is killin' me. Neither my house or work are in a reframed area. However, there are several points on my commute that are reframed, and I did have a chance to eat dinner in one. Holy moly is HSPA+ fast! EDGE is virtually useless with these devices.

you can select mulit bands that way you dont have to use auto as it does turn em off ,i used the last selection it lets you select what you want

Sorry to check in late but with these changes I notice that my signal sticks to 2g and barely wants to switch to H or H+. Maybe when Im off work Im gonna try to select all wcdma band and switch to wcdma only in network mode. when selecting network mode i notice it changes all the settings in the service menu.

that's what I've been doing - COMBI BANDS, and add GSM 850/900/1800/1900 and WCDMA 1700/1900/2100.
But it didn't work for me, phone remains stuck on EDGE -

I dont think this does much only put me in Edge mode or no data at all. Its weird that theres an option for it. So ya no luck here...

Disable GSM, use LTE/WCDMA only

I tried searching however could not find anything. Perhaps I may be using the wrong wording.
What I am trying to accomplish is to disable the GSM mode. What I find is the phone likes to jump to the GSM network and with that the internet connection just doesn't move at all. If I force the phone to WCDMA mode it work just fine standing in the same spot, so the phone is still picking GSM over WCDMA even when there is a good signal for WCDMA.
Current modes:
LTE/WCDMA/GSM (auto connect)
WCDMA/GSM (auto connect)
WCDMA Only
GMS only
Is it possible to have a LTE/WCDMA option?

If I force the phone to WCDMA mode it work just fine standing in the same spot, so the phone is still picking GSM over WCDMA even when there is a good signal for WCDMA.
Current modes:
LTE/WCDMA/GSM (auto connect)
WCDMA/GSM (auto connect)
WCDMA Only
GMS only
Is it possible to have a LTE/WCDMA option?

I miss this option. The Xperia Z had this mode, I loved it. It was reachable via the common code *#*#4636#*#*. But this code doesn't work on the GT-I9505 with stock Samsung ROMs. But even with custom ROM, and working code. This special mode is missing. There are 2 switches for "LTE only" and "WCDMA only" but not both

App doesn't seem to work, when I hit "Select Radio Band" it comes up with "Set GSM/UMTS Band" and nothing else.

You have to use "prefered network type" as seen here

This should work

Here is my screenshot. It only has "LTE/CDMA", which only allows me to use LTE. There is no "LTE/WCDMA" option.
Perhaps, this might be an idea for rom creators?

also interested in this.

yes, please add this function LTE/WCDMA only into ROM CYANOGENMOD.
because LTE/GSM auto (PRL) connect to 2G/3G/4G, and i'm not interested for 2G.

Did anyone ever find a solution to this?

Solution please ! I have the same problem also

True. I am able to use the following:
LTE/GSM (prl)
WCDMA (prl)
GSM Only (prl)
I am unable to use LTE/WCDMA/GSM
I am using XXUGNG8 modem, and I am unable to use 2G (network won't connect).
3G works in most cases, but it is still dropping. Only technology which works correctly is LTE...stable and fast.
I am unable to switch the network band to any other one. I tried it with service menu tool, but it does not work either (allows me to change to defined items above, and reverts back to LTE/GSM if I'll select anything else).
Is there a way to add support for more network modes? I am confident that my issues are not related to HW, as both bootloader, GSM modem and LTE modem are all of the same version - XXUGNG8, and I do have very good reception for whole band. I am just unable to switch over to 2G, and 3G is still dropping.
I live in Prague, Czech Republic, and I own GT-9505i variant

Any solutions guys?

any solution to this date? im interested in the same thing.

I finally found a solution that works on my Samsung Galaxy S5. Enter code *#2263# into your dialer. An option menu will open with "LTE/WCDMA Mode" only as an option. Works like a charm!

Wrong posted.

Hi,
Sorry to bump this but I have the same issue. I have a Galaxy S4 and it is very weird with its network selection.
The default setting is LTE/GSM auto, which I believe is LTE combined with the GSM Auto mode that everyone knows about - this being, prefer 2G instead of 3G in weak signal areas.
I have the following options:
LTE Only
LTE/GSM Auto
GSM Auto
WCDMA Only
GSM Only
WCDMA Preferred
Plus a load of other stuff about CDMA and EvDo (I'm sure that the GT-I9505 doesn't support CDMA or EvDo?).
The problem I am having is as follows:
Immediately when I got the S4, I realized that it was preferring GSM over WCDMA/HSPA. This was confirmed when compared with a Samsung Galaxy Ace Plus, on the same network, in the same location, and the Ace Plus (S7500) was choosing 3G, whilst the S4 chose 2G. Doing a bit of Googling led me to find the WCDMA setting, and after choosing that, the S4 chose 3G.
So all was good for the last 2 years, using WCDMA Only mode on my S4, as my mobile operator (Virgin Mobile) didn't have 4G access. Losing LTE wasn't a problem.
However, now I have switched to the EE network, I now face a problem. As mentioned above, there is the WCDMA Only mode, and the LTE Only mode - meaning that I am unable to have both 3G (WCDMA) and 4G (LTE) without also having GSM, and there is no way that I want to ever use GSM again, especially since that EDGE/GPRS are barely usable as data connections, GSM has sub-standard voice quality, and the S4 is choosing GSM over WCDMA.
A couple of examples, once on my way home, the S4 dropped from 4G to 2G and completely ignored 3G - despite being right next to a 3G mast operated by EE (albeit on the old Orange code). On WCDMA mode, the phone always connects to the Orange 3G mast. Thankfully, a bit later on, it did pick up 4G again, but if I was streaming Tunein Radio, that would have been a disaster (it would have dropped the stream).
A bit later on, on the same journey, the phone also went to 2G, from 4G - despite being in a reasonable signal area for 3G. Why didn't the phone choose 3G? I'd had enough by then and switched to WCDMA Only mode; result? 28% 3G signal (3 bars)!
It's also happened on my local mast, until a few weeks ago. The S4 was choosing 4G from a more distant mast (strength 50%), instead of 3G from the local mast (strength 60%). When I went downstairs, to the kitchen, the signal strength dropped and the phone went straight to GPRS! GPRS is likely to give about 30kbps max, so I don't know why the phone was doing this - although about 20-30 seconds later, it did then go to the 3G from the local mast.
I can't use LTE Only mode as (a) the 4G rollout isn't complete, and (b) the S4 does not support Voice Over LTE (VOLTE), meaning that in 4G only mode, I have no way of accepting or receiving calls.
I need a 3G/4G mode (LTE/WCDMA) on my S4, that doesn't use 2G at all, because 3G/4G signals are present virtually everywhere on the EE network, and it would stop the S4's crazy behavior.
Any suggestions to remedy this would be appreciated. I am not rooted, though if someone knew how to root the phone for me, it could be a possibility, as it is out of warranty.
