I'm trying to use a dual sim adaptor with the Tytn2, but when i turn on the device i get a message saying "smartchip not allowed" and then there is no signal. what can i do?
I can't help you, but i have the same problem... Is it possible to do any changes in the registry?
There is a solution for this problem I've just found it by accident when searching for the same topic. Here are the quotes of people on the forum dedicated to this problem:
"In order to solve this issue, we suggest you to change the network parameter’s of your mobile.Please desable the automatic mode and choose GSM (only) for the network and select GSM (900+1800) + UMTS (2100) for the band selection"
However there is a price for this: "Changing to GSM is disabling all 3G/HSDPA function on the device, so your data speeds will be limited to standard GPRS (50kbps) or Edge, where available (up to 120 kbps)"
Hello Guys,
I'm experiencing a problem with my Froyo Desire for probably a week now.
The thing is that in certain areas my Phone can not receive calls / sms or such. In other words "GSM services" dont work. 3g though works fine (stable, strong and fast connection) My Provider is T-Mobile.
After quite a lot of testing I was able to isolate the error:
When WCDMA / GSM is chosen by the phone automatically it seems to me as if it didnt switch "back" to register with my provider via GSM when i want to make a call or if someone wants to call me.
When i switch to "GSM only" manually everything works fine but i have no 3g of course.
I also experience this problem only in certain areas. I live in an area where there is really strong HSDPA available (up to 7mbit\s). When i go to other places of my city i still get HSDPA (not as strong) but calls / sms still work.
The last paragraph may be of no importance, i don know.. probably it helps..
I have googled quite much about this problem and also found a few persons experiencing the same issue but nobody was able to come up with a solution.
I would be very thankful if someone could try to figure this out.

gsm only Desire?
I'm having a nightmare with 3g 2g connectivity on my Desire on the three network whilst at home. If I could manually select gsm only this would be fine as I could still call and text and use wi-fi. Unfortunately my options are gsm/wcdpa (or whatever) auto or the 3g only.
can someone please advise if it is possible to select gsm only and if so, how?
many thanks
Can someone please advise me how if possible, to set the desire to gsm only?

Wireless and network-Mobile network- should be here somewhere.
Thanks, but there is no option for gsm only. It's wcdma only or gsm/wcdma auto. there has to be a way around this.
Similar problem, different version
I've experienced similar problem.
In some area, I can get steady grps signal when I switched GSM only on; but when I switched WCDMA/GSM on, I could get no data connection at all.
I'm using China Unicom's mobile service.
Solution
Hi there,
I've the same issue and I fix it allowing the option GSM/WCDMA Auto in the configuration menu.
Then enter the following code *#*#4636#*#*, select "phone Information" and set preferred network type, set "GSM car (PRL)".
Sorry about my bad english.
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
exit

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!

Thank you for the file.
I have been busy lately, and I had no time to check in.
I compared the files with a hex editor, and unfortunately there are big differences...
I am afraid to softbrick my phone, so I will research on it a little further.
I tried the methods described at
http://androidforums.com/samsung-ga...rk-frequency-your-samsung-i9000-galaxy-s.html
In the service menu
* # * # 1 9 7 3 2 8 6 4 0 # * # *
If you select:
[1] Debug Screen
+
[8] Phone Control
+
[7] Network Control
+
[2] Band Selection
Unfortunately the SGH-T679 does not have combi-band options.
Key in [4] (tap [menu], than Key in), displays a hidden menu:
"[1] GSM 850
[2] GSM 900
[3] GSM 1800
[4] GSM 1900

[7] WCDMA 1800
[8] WCDMA 1900
[9] WCDMA 2100
If you want to add other bands
choose band that youa want again"
However it doesn't change anything regardless what you choose next.
You can also enter
*#*#info#*#* (*#*#4636#*#*)
and you tap [Phone info],
then you can "Set preferred network type:"
choices are:
WCDMA preferred
GSM only
WCDMA only
GSM auto (PRL)
CDMA auto (PRL)
CDMA only
EvDo only
GSM/CDMA auto (PRL) - default by My phone
Unknown
I tried a few options but no help.
There is also a [menu] key [Select radio band], where choices are:
Automatic
EURO Band
USA Band
JAPAN Band
AUS Band
AUS2 Band
Here it accept any selected band, but i can get no signal in either 900 or 2100MHz.
USE THIS INFORMATION AT YOUR OWN RISK, I AM NOT RESPONSIBLE FOR YOUR DEVICE.
Its been a while since there was no activity here...
After countless reflash and handful of softbricks, My latest findings are:
- the baseband of the SGW does not work with Exhibit II rom - http://imageshack.us/photo/my-images/688/sc20120219093621.png/
- 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,
Hernan

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:
Current CH: 0
Set Downlink CH, Input?
0: Reset
Set CH Range :10562-10842
Set CH Range :9662-9938
Set CH Range :2937-3088
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.
