I use JPG with mine on Rogers.
You can get it here. Flash in recovery mode.

I found KG3 to work the best for me in terms of reception. The other Canadian modems with 850/1900 bands are KC1 and JL2.

Wifi signal is pretty weak for me but i think that might also depending on the kernel of the ROM (I'm currently on deodexed JVX, semaphore 2.0.0, KG3 modem, Bell network). You can always try some of the other gingerbread modems to see if wifi works better, but the 850 band may not work for you.

Thank you, I will try to change.

Sorry, but the kernel has something to do? I have 2.6.35.7-I9000XWJVQ....
Thank you!

I try the modems cwm3_bvjjpg and cwm3_zsjpg and 3g dosen't work, i try to chens the 1900 band to 850 but in zsjpg i can't because in the menu says "this menu don't esxist" and the WCDMA 850(FDD V) is number 6 in the menu.
With the bvjjpg I put the [5] WCDMA 850 (FDD V) but when I put *#0011# WDCDMA still have 1900 band 2....
With the modem UGKG3 i don't change enithing in the menu and the 3g works, but I think the 3g is slow and the wifi is not good....
Thank you!

Best Modem for Bell i9000m and ICS?

My phone is the i9000m Bell and I am on TeamHacksung v.14 and wondering what is the best modem to use?
Right now I am using UGKG3. It works but its not very strong for signal.

I used UCKG3 and it's fine on 850Mhz which is what Bell uses. To check you're on 850 dial *#*#0011#*#*
I can't post links but google 850 i9000 for instructions on how to add the 850 band if your phone isn't connected as 850 CDMA

when I do that dial this is what I get
UMTS: HOME(CS+PS)
RRC State: IDLE
WCDMA 850 band 5
FREQ DL: 1087
FREQ UL: 862
CELL_ID:*****
PSC:7a
RSCP:-101,ECIO:-10

Well you are on 850Mhz but your signal does seem low, maybe a low signal area?
If you poke around in this thread you can try other 850Mhz modems, some might work better in your location. Finding the best modem for your carrier/location seems to be a lot of trial and error

thanks rax22... I will check around.

I tried this test and it says:
WCDMA 1900 Band 2
I am in Southwestern Ontario Canada.

Same with me. I'm currently in an office with poor reception, but my settings read
UMTS: HOME (CS+PS)
RRC State: IDLE
WCDMA 1900 BAND 2
Reg PLMN 302-610, IsPCS? 1
FREQ DL: 587
FREQ UL: 187
CELL_ID:0x_______
LAC: 0x2936
PSC: 142
RSCP: -110. ECIO:-14
I was unaware that flashing a different modem may improve my reception/service, I thought it was a sort of works-or-not thing. If anyone would care to help as well that would be great
(sorry to OP, don't mean to steal thread, only gain help from it as well)

Are these two showing the signal strength?
RSCP: -110. ECIO:-14
If so what do they mean and should they be higher or lower for better signal. I have been trying lots of different modems and trying to figure out what works better for me.
thanks.

You can't use anything other than 850/1900 on Bell. 850 is for downstream, and 1900 is for upstream. KG3 is the only radio that is known to work with Bell.

I tried the JVT modem today and it worked. Ran a speed test with wifi off and got some decent results. I did go back to KG3 though.
Can I ask exactly which KG3 modem file you are using? There seems to be a few different ones floating around with different names and file sizes.

Where did you find that because it's not in that link that was listed here. Also, what region do you live in because that could have something to do with it as well.

nope
850 and 1900 are two different bands. Both can work both ways.

I'm using the UGKG3 , Since this is the baseband they gave me with my Bell Samsung S Vibrant, I managed to find an ICS rom using UGKG3 here on Xda. Might want to try it out.

No, it does not work for Bell phones. I already tried it and it messes up Hacksung rom badly.

[Q] Modem question

Hi All..
I have been having some peculiar problems regarding modems and was hoping someone could share some insight on it.. I get my modems here: http://soggycashew.weebly.com/index.html , and currently am on MIUI, but the same problem that I am facing persists with CM7, ICS, or any I9000/I897 roms too.
First off, I'm from Malaysia and using Celcom, thus these bands are used:
3g: WCDMA-2100
2g: GSM-900
The problem that im facing is, whenever I flash a modem that doesn't have 3g 850mhz by default, I break my 2g.
Something like this: Flash a modem with 850mhz by default (ones that i tried: UGKG3,BVJJW2,UGKC1,UGJK4), everything works fine.
Flash modems that don't have 850mhz by default (ones that i tried: ZSJPG, DXJV9, ZSJV6), 3g works fine (wcdma 2100) but 2g is broken and if i force it to "2g ONLY" i get emergency calls only. Checking the service menu, i realise that it is getting a signal from another carrier using the gsm-1800 band, but doesn't get anything from home network on gsm-900 band.
Any idea why and how to overcome this?

Hmm... Use one of the modems that work for you, and the problem is solved!

You can try looking at samfirmware.com see if there is intenational package for your are and pull our the modems then put it in a cwm scrip for cm7/ics.

Yea, that works too, but all the modems that work are not even remotely meant for my region.

Actually the modem that is used here officially for the i9000 is DXJV9 and already available and is one of the modems that I tried but is giving me the problem..
I'm using BVJJW2 for now, somehow UGKG3 heats up my phone very fast.

I have similar problem.
My cappy can use only 2G network but not 3G.
I am running on Doc's Master ICS V3.1 with its default baseband.
Is there any one facing the same problem ?
Please advise.

[Q] Can't connect to 850 AT ALL

Hello everybody I'm having a bit of a problem with my SGS i9000, international version. I'm currently running CM7 with the UGJL2 modem.
I recently signed up for a data plan. My carrier is Movistar Chile.
Problem is, I can't connect at all. Not even on EDGE. I have checked the APN settings and they're OK.
I have also tried changing the settings in Service Mode to no avail. When I choose any other setting than GSM 1900, I don't get any service.
Also tried changing some settings in Testing. Nothing.
Tried flashing many modems, most of them with 850 enabled, no good.
Any ideas?

I might suggest to flash a different modem or one of the radio 850mhz files found on this site.

I can't recall if I tried that modem. Will flash and check. Thanks for your responses!
EDIT: flashed KC3, no good. There's no way it'll connect with 850, just 1900. Tried changing settings in Service Mode, nothing.
Maybe flashing another ROM?

Try this for 850mhz
I am on Telstra in Aussie and we use the 850Mhz, and when I upgraded ROMS I had to sort out the same issue you are having. I found a Telstra modem, opened a modem file, swapped my modem into it and put it into my phone. The in recovery opened the file an it all worked. Not sure if that is the correct way, but it works for me and gives me both 850 and 2100 for Telstra.

Change your rom to jvu, its sweet, and try to use the modem that was in your stock rom from chile
Im using simplicity + semaphore+ UGKG3 modem

Thanks for the reply. Sadly, the phone was imported all way from England... not the smartest thing to do...
So tecnically there is no stock Rom for the I9000 from Movistar Chile.
However, now that you mention it, Movistar used to sell the I9000B here, and I'm not sure if I could grab the modem file from a I9000B from Chile (if I happen to find one) and flash it. Are I9000 and I9000B modems compatible?
EDIT: found out something weird. I actually got a hold of a SGS2, factory unlocked, and swapped the SIM cards. In the SGS2, the APN settings from Movistar Chile are picked up automatically (preconfigured?), thought there is still no connection when Data is enabled. This (APN settings preconfigured) DOES NOT happen on the SGS1, as if there weren't any settings predefined. I have to put them manually. Why...?
With the other SIM card (Entel Chile), both phones set the APN automatically and connect to the data plan without issue.
Does this mean there's a phone issue AND a carrier issue?
I also forgot to mention that I got rid of CM7 and flashed the latest Darky's Rom, JVK modem, 850 enabled as far as I know.

The apn issue is from the preloaded apns from the rom you uses, it happened to me no other than simplicity.
The letter b on i9000 means the region, from example im in mexico and i have a i9000t that its for latinamerica, the i9000 alone its erupean and MAY BOT HAVE 850mhz antenna
Do you had 3g before the data plan weon? Hehehe

Ohhh, so the APNs are Rom related? Interesting, I might try flashing another Rom. Thanks
I have flashed Captivate modems on the SGS and they work. Could I9000B modems also be compatible?

Dont know if i9000B have 850 MHz
Bit if it have, it will work

It should have 850MHz, since that's supposedly the frequency Movistar uses here...
Still trying to figure out what to do

Have you tried to make sure it is enabled in the network mode/cell info/power info menu
in your dialer: *#0011#
and make sure under all the options 850 is enabled

Thanks for the reply, but I already tried that, didn't work SGS doesn't support 850mhz out of the box, which is why I flashed another modem in the first place.

Ok there's a cm7 radio zip it worked for me when I was on it ill find the link and post soon.
Found it here top of the page - kg3
