here in Mexico, Telcel we use 850mhz and none of the modems (including KD1) work on 3g, and I see no difference in 2g :( but I do get signal.

I've read all of the pages of the thread and I think 850mhz will not work on these modems :(

I tried "forcing" them into WCDMA only (3g) and lost all signal unless I am missing something, but if someone knows how to make them work at 850mhz I will appreciate it :D

i had a problem of network detection with a ROM named WeUI 0.8.6 by NightShack0

gotta say the first KB3 solved it once and for all and guess what it increased my download speed too so thank you so much for this
[Galaxy S I9000 Android Development] bopsch:
I've tried both modems and both seemed to work - at first...

Both the KF1 and the KB3 modem worked for me regarding data connection (2g and 3g). Pretty good indeed, but not much difference compared to JVU (i.e. for me)...

The sad thing however was that when I received a call by someone or when I called someone, I could not hear anything and neither could they.

Everything else was working fine (messaging, GPS).

Location is Northrhine-Westphalia, Germany, carrier is T-Mobile and current ROM (on which I've tested these modems) is Elite 7.1 beta (IMM30B)

Can anyone confirm this?
[Galaxy S I9000 Android Development] wogfella:
That could be the evil HelloHello bug. Next time it happens try muting and unmuting your phone.

If it goes away for that call, that's your bug. If not....try a different modem??
[Galaxy S I9000 Android Development] wogfella:
Ummm...maybe the modem IMPACTS something that may cause a lag in your wifi...considering these modem files are not actually supposed to be for our phones it's plausible.

But speaking as someone who has messed about (badly) in the code for kernels and took a long look at the RIL, I can tell you....no. Modem does NOT control wifi.

Kernel only matey.

I'm so happy with the KF1 modem.

Sometimes the signal goes away (super extreme ultra rare) and i have to wait a few secs to get a new signal.

I have almost always a better signal strengh and my battery life is great with it.

Now i can even do 1h of tether, and the bat wont get under 80% (with JVU ~60-70%).

Carrier: o2

Country: Germany

City: Mayence

GSM-Frequenzies: 900/1800Mhz

Modems tested: AUKF1, XXKD1 and XXKB3

Modem used before: XXJVU

KB3 did connect but only GPRS was possible.

AUKF1 and XXKD1 are working well but reception with KD1 seems a little bit better. I also chose the second modem because of the matching language code.

Didn't test the download speeds as I suppose this has mainly to do with the time of day and how many people are currently using their mobile internet.

Thoroughly testing would be neccessary which I am too lazy to do. So I simply ignore that as long as the download is decent, which it is.

Call quality with KD1 is good, though the voice of the other person sounds a bit artificial and tinny. But the awesome feature that the modem switches from 3g to HSDPA outweighs that :) Dunno if this has any measurable impact on battery life... Speaking of – couldn't tell any difference to JVU.

GPS fix in a matter of seconds – as with almost every modem I've ever used. ;)

Download JVT here, put it in the root of your internal SD card and flash via CWM.

p.s.: Did you try KD1 – it works good for me. We are at the same carrier and we are in the same country. Would be interesting to compare the findings!

Screenshot below shows my testings with KD1: notice the big scatter.
[Galaxy S I9000 Android Development] test123456789012:
Tested KB3 again and this time HSDPA and 3g worked. The modem also switches from 3g to H automatically but stays longer on H. Maybe this is why the download speeds are better with KB3 compared to KF1/KD1. I'll stay with KD1 though, because I reckon that staying longer on 3g may improve battery life.

Edit: Packed a XXKF1 and flashed it. Everything works like with XXKD1 but reception is a bit worse (-77dBm compared to -69dBm) so I didn't bother and flashed XXKD1 back. Look at my later post for download links for XXKF1.

My rating for those four modems would be (best on the right):

XXKB3 < AUKF1 < XXKF1 < XXKD1

cheerz.

** Sorry if this 2nd part is off-topic'ish because JW4 is a stock I9000 modem **

I extracted modem.bin from the ROM, put phone in airplane mode, replaced /radio/modem.bin with the one from JW4 ROM (I lazy'ly did this with root explorer), rebooted phone and then disabled airplane mode again.

Does any body have direct link for XXJW4 Modem Only
[Galaxy S I9000 Android Development] lockzackary:
I tried this for a week and here are my findings:

(note: location is Philippines at any area in Luzon)

having only two major telco's in our country, its easy to identify which places we would receive bad reception

I would just like to post this for the benefit of other Pinoys who'd like to test the modem

In reality, this really enhances signal reception

including wifi --> I believe the JVU modems had a cap on wifi data transfer (maybe for battery saving purposes), which was lifted-out when switching modems to either KF1 or KB3

Unfortunately, the KF1 and KB3 modem has priority over 3G signals, and seems to disregard 2G signals

I am not sure about this but I tried doing a modem dance, and a 2G signal was never picked up on my usual hang-out places (where before when I was on JVU, I get at least 2bars of 2G signal)

So here in the philippines, since 3G is not everywhere, you really could not extract any benefit at all with this modem

except if you are on the metro (Central Manila, Makati area)

[Galaxy S I9000 Android Development] -Loom-:
I too noticed that KF1 is reverting to 3G, and quickly switching to HSDPA if needed.

I spotted a similar behaviour on some kind of modem back in the Froyo days.

I just wonder if 3G is really helping to conserve battery. 2G for sure is, but whatever I do, once I switch to 2G, it never finds the way back to HSDPA, It just stays on 'G' until the next reboot. I have yet to find a modem where the switch to 2G and back to HSDPA is working flawlessly all the time in all directions.

I was extremely happy with KF1. Because it kicked away the nasty "hello hello bug" I was having since 3 months. But suddenly I'd notice that signal strength is less, maybe even weaker than JVU. Now I'm back to JVU, and again weak signals but no HHB yet! I'll stay with it for a while.

I moved KF1 modem.bin into a stock/gingerbread compatible cwm zip and flashed it.

Seems pretty good on my JW1 rom, may be a placebo but the connection seems pretty stable in my room (which usually has slow transfer speeds). Bars haven't changed much (possibly spends slightly more time on 2 bars, it's hard to objectively tell). 2G and 3G seem to work too.

The only thing left to test is GPS... hope it works lol.

I've uploaded it for anyone who wants to try on stock gingerbread.

Going to try KB3 now.

EDIT: went outside to test GPS on KF!, got 9 sats lock within 10 seconds, this is better than JVU =)

EDIT2: KB3 3G working good too, signal seems to be identical to KF1. Now will test 2G and GPS.

[Galaxy S I9000 Android Development] .:Crack:.:
I'm using Eplus. But when flashin XXKF1 and looking into settings-info-status it says "kein Betrieb" (or somethig similar) under "Servicestatus". On UCKF1,XXKB3 (*),XXKD1(*) as well as on XXJVU and XXJW1 it says "In Betrieb".

*When flashing them on top of UCKF1.
[Galaxy S I9000 Android Development] lohho:
I guess thats because Eplus has bad network, mainly the old 2g (edge) one in the most areas.

Problem with all those modem is that they simply dont support ANY 2g networks because the 2g chip on the sgs is diffrent and thatswhy you don't get any reception.

JVU or JW4 would change to 2g, thatswhy you got reception with those.
[Galaxy S I9000 Android Development] -Loom-:
I'm using KF1 with Vodafone Germany, and when HSDPA or 3G is not available, the modem is using "G".

So, recpetion is given in all available standards.
[Galaxy S I9000 Android Development] lohho:
DO you really have a SGS I 9000? ^^ - i can't get any 2g connections with tmobile, no matter what i try (with those modems).

Edit:And btw: G (i suppose still a 3g network) != E (2g network). Try to get E with those modems.
[Galaxy S I9000 Android Development] -Loom-:
Sure I got an SGS I9000 ;)

Simple overview, from slow to fast:

2G = GPRS

2.5G = EDGE

3G = UMTS

3.5G = HSDPA/HSUPA

So, basically there are two groups (or generations)

GPRS & EDGE + 3G & HSDPA

Each group shares the same standard, but EDGE and HSDPA are evolutions of the original standard, providing more speed.

Those Nexus modems are quite difficult to install. I had success only when I flashed JVU or JW4, then KB3, and afterwards KF1.

A jump to KF1 directly from JVU/JW4 did not work. And don't forget to reboot between those modem installs.

And I'm not sure about EDGE availability for T-Mobile or Vodafone. I haven't spotted an EDGE connection ever, at least with Vodafone Germany.
[Galaxy S I9000 Android Development] lohho:
So if you switch to "use 2g networks only" do you get any network?
[Galaxy S I9000 Android Development] -Loom-:
I usually don't switch manually.

But in areas of weak reception, I see "G", meaning it's the slowest speed in the 2G network.

I tried the power-saving features once, but never got them to work. I assume the problem is more in the implementation of the switching method. When I manually switched to 2G, I never got back to 3G or HSDPA - until the next reboot.
