Dear colleagues,
I have bought a Diamond in France 1 week ago and tryed to flash its ROM to a quad-band one. My device is hardSPL with diamond-hspl-1.24 and flashed the ROM 1.93.831.1 WWE.
Follow the device information:
ROM version: 1.93.831.1 WWE
ROM date: 07/18/08
Radio Version: 1.00.25.05
Protocol version: 52.29.25.12H
But is still appears at phone settings section to select GSM/UMTS band only:
UMTS (900+2100) + GSM (900+1800)
What could possibly be wrong?
Thanks.
Your radio is a quad-band radio, so you have quad-band now, if it does not show up it maybe because of the ROM that you are using, but if you were to go to a place that uses the 850 band it will pick it up, even if its not shown there, as long as you leave it on auto.
Thanks, but are you sure? Just to confirm. I am not doubting on you.
Which English ROM may I use to show up the settings GSM (850+1900).
Thanks again.
I forgot to say that when I try to make a videocall a message shows up saying that the 3G network is not available. And I am on an area with 850 MHz (State of Minas Gerais, Brazil; operator TIM).

You have a Europe Diamond, it wont work on any Americas network.
You need a US spec Diamond to work on the 850mgz 3G.
Up till know it has almost been confirmed its a Hardware matter.
All diamonds are quad.

If you say all diamonds are quad what is the problem in working in americas networks? Of course with the right rom.

As far as I know ROM has no important effect on Radio. For they are independent. Thats why they are flashed separately.
GSM frequency is one thing and another is the 3G frequency.
Greetings.
to confirm that you have 850mhz gsm which is quadband, goto phone and enter
*#*#364#*#* to launch field test.
now under the BAND section it will say 850 when you are using that frequency. try it when your in a mall or underground somewhere otherwise it will say PCS wich is 1900mhz.
i recommend leaving your phone settings to AUTO.

Ok, your phone have quad band on the GSM network, so you'll be able to use the EDGE, and GPRS data and phone service, while the 3G band on your diamond is Euro spec, so it won't pick up the 850Mhz/1900Mhz band (instead it'll pick up 900/2100mhz band).

That's correct, I didin't realize you were talkink about 3G, you'll not get it with a european diamond.
It's really strange. Me with my two friends have two T-mobile MDA Compact IV from Germany and one O2 XDA Ignito from UK.
In Menu Start-> SERVICES-> BAND-> shown:
1st) T-Mobile Germany was with original 1.37 German ROM, but I put original T-Mobile UK 1.37 ROM WWE. In both ROM's was same info.
"Select your network type"

(Where is WCDMA?!!!)
"Select your GSM/UMTS band"
- Auto
- UMTS(900+2100)+GSM(900+1800)
- UMTS(850+1900)+GSM(850+1900)
2nd) T-Mobile Germany was with same original 1.37 German ROM, but I put Diamond.ASerg.23.RUS.
"Select your network type"

- UMTS(850+2100)+GSM(900+1800)
- UMTS(850)+GSM(900+1800)
- UMTS(1700)
3rd) O2 XDA Ignito from O2 UK (original UK O2 1.93 ROM WWE):
"Select your network type"
- Auto
- GSM
- WCDMA
"Select your GSM/UMTS band"
- Auto
- GSM(900+1800)+UMTS(2100)
- GSM(1900)
Why is the difference in network's shown? Is it means that T-mobile MDA Compact IV (HTC Victor) have different hardware?
Does new ROM affect available network type?

the bands in setting can show any bands all they want, but it will only work if there is the 3G chipset to use it. So even if your phone show 850/1900 on a Euro Spec diamond, it's still not going to work with US 3G. The only reason that it showed them all is probably the rom that you are using have all the known bands to show in setting by editing the registry.

Ok. Thanks. But how can I know the chipset I am using and if it is a 3G chipset? And more, When buying another phone how can I know it works in over 3G in any band?
Another thing: Taking a look in HTC french web page, in "diamond specifications" we can see:
Europe/Asie : 900/2100 MHz, USA : 850/1900 MHz
GSM triband/GPRS/EDGE :
Europe/Asie : 900/1800/1900 MHz, USA : 850/1800/1900 MHz
My Diamond was bought in France.
Sorry ... but I think you are wrong saying that it is any hardware issue or that it won't work. Please see existing threads in Raphael section, it has already been discussed.
As for Diamond !! we are 100% sure that the hardware is fine for all bands (3g and gsm) except WCDMA 800, as the calib data does exist and the hardware itself is capable. All Diamond I have seen so far have an rtr6285 and also the newer radio firmware support all bands except WCDMA 800. If using newer radio doesn't work (quadband enabled), so it is a ROM/SPL issue as it seems or your device needs updated nvitems.
As for Raphael, it is the same, except that this one might have an hardware issue (antenna).
We (me, cmonex and olipro) are working on this issue already. Once we get the diag port running on EU Diamonds, we are sure we can enable it for all bands (except 800 WCDMA).

Woooow give me some hope.
But I was 100% convinced that my euro spec Diamond could never join 850/1900 bands.
Only GSM but not 3G at 850.

Hi everyone!
does anyone know if it is possible to enable 850 & 1900 Frequency bands on the I8150? if yes, please, please, some leads for the procedure (Root, or Custom ROM or whatever it makes it work!) i´m not an expert unfortunately.
Just bought an I8150 in Malasya 900/2100 Band which does not work in my country 850/1900 (my fault, didn´t check) so i´m at present using my I8150 as an expensive 2G with a fancy Calendar!.
Thanks lot for any help!!
Hi
First, this is possible, using Samsung Service Mode.......
easiest way to do it is with this App:
https://market.android.com/details?id=com.nfye.insanity.toolbox&hl=en
It has option to enable bands in Secret Codes:
Band Selection.....
Also, read here, but for i9000, so careful:
http://androidforums.com/samsung-ga...rk-frequency-your-samsung-i9000-galaxy-s.html
Hi,
If you don't want to install nitrality (because it needs a rooted phone), you can always dial the band selection service mode directly: *#2263#
For some reason, nitrality does not work on the phone.
The band selection I´ve already tried but no asteriscks appear, selected the options anyway, but nothing happens (even after rebooting).
Thanks anyway, if you have any other comments let me know, you never know..
Hold on there!
this may sound extreeemely roocky (which in fact is) but,
do i need to have the phone rooted so when i dial the band selection in service mode the changes take effect?????!!!
Also, now i know why Nitrality didn´t work.
So i guess i´m gonna root the phone, if you have any link to recomendable instructions let me know, otherwise i´ll look over the net.
Thanks, hope this is the clue to the whole thing
Hi all,
my questions are similar to the ones joan10 asked and thus I'll simply add them to this thread.
(1) joan10: I'm very interested in your progress. Could you please post whether you got the 850MHZ band working or not? Thanks in advance!
(2) Does Samsung ship different versions of the i8150? I'm asking since the Samsung Hongkong website explicitely states that the i8150 is a UMTS (3G) quadband device. However most resellers (and actually most websites like gsmchoice.com) here in Europe sell the phone as a dualband UMTS device.
(3) If there are different versions: How do I find out in advance if the phone I'm buying is a Quadband UMTS device? I guess that the usual sales assistants in electronic stores cannot tell me. I intend to buy the phone in Europe.
(4) Given the posts in this forum, I guess that I will have to enable all bands manually using the so called "service mode". Is there any reason why Samsung does not ship the phones with that configuration even though it is a quadband device? Are there any disadvantages if all bands are enabled?
(5) Will I have to root the device in order to enable all bands? If so, will that affect the warranty?
Thank you *very* much in advance!
Hi,
I can tell you about the experience I've had with the SGW (i8150) and 850MHz UMTS. I bought the phone from UK to try it in my country which uses GSM-1800, UMTS-850. As of today I have not been able to connect to the mobile network, even after rooting and trying different ROMs from Europe and Asia.
I also tried to selecting the 850 band from service mode, but like you mentioned, the asterisk does not show up at 850.
My phone company regularly publishes a list of the phone models that are compatible with its network, and to my surprise the SGW is listed there but with the model i8150B, firmware versions: I8150BVJKJ5 and I8150BVJKH1.
From what I have read in this forum, I suspect the i8150B is a model first launched for the Brazilian market which uses UMTS850 and UMTS2100. So i8150B probably has a different antenna design.
I've been thinking of getting a hold of an i8150B ROM and flashing it to see what happens, or perhaps I'll just give up and try to sell it.
If you do try it, plz update here with the resaults... Hope it will work!

Hi freditoc....
I have the opinion that you will need a suitable, for your region, Phone i.e. Modem/Radio FW to take advantage of the Bands in your area.....
I think the phone has the radio HW OK.....but needs the proper Regional FW.
Perhaps there is a way with ODIN to flash sepetately regional Phone FW?? and keep other upgrades.....
I don't think Euro or Asian Phone FW is appropriate in America.....South/Central???
So maybe more research for ppl who bought Euro or Asia phone, but want to use in Brazil or Costa Rica, etc.
Makes sense....No or Yes??
I think this is mentioned in the I9000 thread I referred to earlier..

I have a SGH-T679 (EXHIBIT II), that I use in Europe and My local providers use 900/2100 MHz for UMTS (3G).
I can connect to any GSM network (900/1800MHz), but no 3G service because 850/1900MHz US radio.
There is no way to put the * to 900/2100MHz in the service menu only 850/1900MHz.
I think that the baseband sw is diferent and it might work for SGW and that of the SGW for the Exhibit II.
Here is the backup of My radio.bin http://www.mediafire.com/?vtbrp8ecwyxtfdx . Baseband T678UVKJ1.
Please upload some European i8150 basebands.
You can use adb and following commands
adb shell
su
dd if=/dev/block/mmcblk0p8 of=/sdcard/modem.bin bs=4096

Hi all,
I'm really interested in the outcome of that discussion. However I'd have some additional questions:
(1) Wouldn't it be possible to simply read out hardware information from your devices? So that you see which UMTS module is built into your device and find out if it's quadband-capable?
(2) Can you tell me what the file 'modem.bin' acutally does? Why doesn't Samsung deliver the devices with only two bands activated?
Thanks in advance!
Sorry, there is a mistake in my last question. I wanted to ask "Why does Samsung deliver the devices with only two bands activated?"
Additionally, I want to refer to the Hong Kong website from Samsung (..samsung.com/hk_en/support/model/GT-I8150FKATGY-techspecs), which states that the phone is a quadband UMTS device. Maybe you can get the appropriate firmware from Samsung Hong Kong.
Please let me know about any progress. Thanks in advance!
Cheers!

Its been a while since there was no activity here...
After countless reflash and handful of softbricks, My latest findings are:

- you can crossflash the Exhibit II with SGW rom - http://imageshack.us/photo/my-images/821/sc20120219100916.png/
Issues are:
- swapped keys,
- no camera,
- can't enter into service mode and
- no 900/2100MHz 3G !!!
Basically everything else works.
And NO, there is NO overclock, the phone runs on stock 1024Mhz.
i8150 with 850?
Have you got your i8150 working in 850? Do you have the baseband file?
Thanks in advance,

The band selection menu can be accessed by dialling *#2263#.
I tried Menu key -> Key Input -> 4
The list of 9 bands came up, but nothing happens after selecting any one of them.
Strangely, if I select [2] WCDMA Band Preference -> [6] WCDMA ALL (that means it's on WCDMA only and it receive signal of all bands), the 850MHz-only network in Australia (Telstra NextG) came up in manual network search under Settings -> Wireless and network -> Mobile networks -> Network operators.
If I select [2] WCDMA 2100, Telstra doesn't come up because it uses 850MHz.
I'm on Vodafone Australia which uses 850MHz and 2100MHz in metropolitan areas and 900MHz in rural areas.

One more bit of information that might help you fix this.
In Service Mode -> MAIN MENU -> [3] UMTS RF NV -> [1] RF NV READ and [2] RF NV WRITE,
There are 4 bands,
[1] WCDMA 2100
[2] WCDMA 1900
[3] WCDMA 900
[4] WCDMA 850
That means the phone is coded to get reception from these 4 bands.
But when I tried to get in [2] RF NV WRITE -> [4] WCDMA 850, the process com.android.phone crashed. Is that a corrupted program file? Is this the cause of the problem?
Under [1] RF NV READ, information for all 4 bands can be accessed.
Hello. I would like to get a Galaxy W too, but I have the same problem as you: In my country 3G uses the 850 frequency!
Please let me know of your progress. Some Android devices come with a baseband changer (cyanogenmod 7.2 on Motorola Defy), but maybe it's because the phone does support both frequencies?
Thanks.

Some Brazilian guys on this thread have the GT-I8150B, which seems to work with the 850 band.
http://forum.xda-developers.com/showthread.php?t=1466740
Here you can download 2.3.6 brazilian firmware for that model and extract the radio file to try on the GT-I8150 if you're brave.
http://www.sammobile.com/firmware/
If someone tries, let us know how it went!
My Galaxy W was sourced from Hong Kong and it was marketed as a quad-band (850/900/1900/2100) 3G device by both Samsung Hong Kong and the only 850MHz 3G carrier in Hong Kong, SmarTone. (Note that my phone is not network-locked.)
I notice that the CH configurations for WCDMA 850 are missing from service menu.
Under Service Mode (by whatever means you get in) -> MAIN MENU -> [6] COMMON -> [5] WCDMA SET CHANNEL:

10562-10842 are 2100MHz DL channels
9662-9938 are 1900MHz DL channels
2937-3088 are 900MHz DL channels
4357 – 4458 (850MHz DL channels) are missing
As DL channels of 850MHz are missing from this menu, my phone couldn't have possibly registered to any 850MHz network.
Is there any way to add them to the phone? Samsung is supposed to have done that, but they left it out.
Firmware version: I8150ZSLM4
According some other websites, the version number can be explained as:
I8150: model, ZS: China, Hong Kong, L: 2012, M: (Unknown month) 4: Version
Did anyone ever figure out if this is possible? I don't understand why the specs for this phone show 850 as a usable band if it's impossible to use.
i have a galaxy s plus.
i want to enable the 850 mhz band.
anyone know how?
i have a Galaxy S I9000, i'm supose it's similare:
On y phone, 850Mhz band is desactivated by default.
try on phone keyboard:
*#*#0011#*#*
You must arrive on a menu:
do back and go to Phone controle and Band Selection
Doing this enable band activation on software, if your phone's modem not enable to working with this band, the result is it's not working with the band frequency anyway...
I'm try this for enable USA 3g band on my I9000 from europe, and i'm able to activate band, but it's only partialy working (have 2100Mhz 3G (VTR) working with this, but not the 900Mhz/1900Mhz band used here by Movistar(Chile) for 3G.
it does not work. i see the menu but when i press
back, i do not get anywhere
A family member gifted me a Galaxy S4, however it is the SGH-M919. I currently live in Europe and 3G bands in my region are GSM 900/1800. At the moment I can't access 3G and any other type of data for that matter (LTE is not supported here). Is there a way to change T-mobile 950 and 1900 bands to my region ones?
Thanks for taking your time to answer
Sadly not.
Since the radio does not support those frequencies for hsdpa

So there's no way to fix it?
Hello Flex,
I have the same phone "Samsung S4 SGH-M919 - Tmobile" and I live in Hungary, it works fine with me all you have to do is just to switch form WCDMA/GSM to any other option "like GSM only" then back to WCDMA/GSM as a kind of refresh and the 3G will work fine after that, you can find this inside Settings > More Networks > Mobile Networks > Network mode, but unfortunately you have to do this every time you restart your device.
There is also another alternative solution is to reset the Access point names to default, you can find this inside Settings > More Networks > Mobile Networks > Access Point Names.
to be honest I don't know the reason of this error, but try what I described and tell me if it works with you.
Good Luck
Well. I have the exact same phone and have tried several ROMs, either custom or stock and basebands also. Nothing seems to work. The very few users who reported it was working didn't provide much evidence of it. Even Wikipedia says no 3G 900MHz availability for this phone. A simple edit to NV 1877 values won't solve it. I've tried that too.

so you saying am on 3G actually but the icon will be displaying the 4G.?
i used an app intelli3g to switch but still showed 4g.
could it be that am on 4g and predetermined on phone.?? could i access the hidden menu and select the 3g band? ??'
i dont need 4G..
Dial 277634#*# on dialer which will open up hidden menu go to field test / modem settings / network mode try changing different wcdma version but i dont think ur 4g is going to change like i told u even in g3 3g its shows 4g...u can try subscribing to 3g packages of ur carrier thats how i avoid that too
