Which one kb3 or kf1?

Sent from my GT-I9000
[Galaxy S I9000 Android Development] XlAfbk:
here's my results (with each modem 2 runs) on german o2 network

KF1

signal 81/83(79-85)

ping 285/164

down 1303/1294

up 359/362

calls are crystal clear and a lot louder than with i9000 modems. great improvement

KB3

signal 79/79(77-83)

ping 204/147

down 2227/2514

up 1623/1596

calls not tested yet

KB3 is clearly far supperior on speed. Signal and Ping varying too slightly to make any clear statements there, would need a lot more tests to get valid results with such small variations.
[Galaxy S I9000 Android Development] Luiwammes:
Ok, I had my doubts as to this would actually work at all, but after all the positive responses here I decided to have a go.

I'm on Android 4.0.4 (Dark Knight 3), using Telfort (=KPN Network) as my provider. The office I work from is right next to a cellular station.

With JVU I got -69dBm when outside and -93dBm when I go as deep in to the office as possible.

With KF1 I got about the same results HOWEVER I was only able to make half a phone call. The other side complained to me that she could hardly understand me. After that call I tried several times, but always ended with a dead line.

With KB3 I also get anything from -69dBm to -93dBm and have been able to make a call without the other party complaining.

Honestly, so far I've not been able to notice any real difference with my JVU modem. Also my battery seems to discharge as fast as before. I'll keep using KB3 for awhile. If I come across anything worth mentioning I'll report here again.
[Galaxy S I9000 Android Development] xchasa:
Kb3. It seems better than kf1.
[Galaxy S I9000 Android Development] alcaprone:
From the comments and my experience (I'm from Italy) i suppose that KF1 is better for Europe-Asia and KB3 for America..i think it would be useful for everybody to state in each comment in which country we reside
[Galaxy S I9000 Android Development] xchasa:
I'm Australia and Kb3 is better here for me..
[Galaxy S I9000 Android Development] alom5:
I think I've is same as ...if not inferior to jvu.

kb3 looks like it may be very slightly better than jvu..tho its hard to tell add the signal strength is very similar. It does seem to have better speed on hspda. The GPS is not as good.

This is early stages as only had it an hour or so.....I will test it a bit more and post back.

Running docs v5 ics rom
[Galaxy S I9000 Android Development] .:Crack:.:
Flash UCKF1 and then XXKB3 OR XXKD1.

Yes, especially because UCKF1 has capped upload speeds.
[Galaxy S I9000 Android Development] HiKsFiles:
ok, so no luck for us canadian even with the KD1 modem ?

I went through all the pages and all I can see is that nobody got any modem to work properly here in Canada.

Am I correct ?

I really could use a better modem as I litterally work in a Faraday Cage ! :mad:
[Galaxy S I9000 Android Development] bhu1:
both modems aren't working in india here for me.
[Galaxy S I9000 Android Development] karapoutsoglou:
Damn, im so happy with kf1, the worst part of galaxy was its modem all the time.

Now with that super modem:p i have signal even....in the subway.:eek::eek:

And the calls are like crystal.

But the speed of kb3 puts me in thoughts...

to flash or not to flash?

Kf1 is working for me in Hyderabad India on th ics.
[Galaxy S I9000 Android Development] ivke101:
More dbm is beter or not?
[Galaxy S I9000 Android Development] sa1yan:
I can tell you that the KB3 has pretty good voice quality as well. Nothing wrong with flashing and testing! The signal can fluctuate though, KF1 is an all rounded modem for me :P
[Galaxy S I9000 Android Development] bennybaz:
JVU on Orange.
[Galaxy S I9000 Android Development] r3loaded2010:
These modems work perfectly for me, right up until after my first call. After that, any calls I make connect, but there is silence on both ends of the call (other party can't hear me, I can't hear them). A reboot fixes this, but it's only good for the first call made after the reboot, then it's back to the same silent call problem.

Reverted back to JVU since that works well enough for me.
[Galaxy S I9000 Android Development] loonieryan:
Just tried KB3 on a i9000M and it doesn't work at all with Rogers.
[Galaxy S I9000 Android Development] fuzzvirus:
xxkd1 is Good for me on swisscom
[Galaxy S I9000 Android Development] ashwinds:
on BSNL - both DO work for me... settled on KB3, but i havent seen 3G in a while ... only Edge. Must check.
[Galaxy S I9000 Android Development] powerdams:
I have exactly the same problem with KF1, really sad because without this bug it will be a perfect modem for me...
[Galaxy S I9000 Android Development] bhu1:
jaipur, vodafone. not working, both.
[Galaxy S I9000 Android Development] jrafael:
Nope, lower dbm=better signal
[Galaxy S I9000 Android Development] LowRider150:
On My Galaxy S 4.0.3 Milestone 4 ICS both files doesn't work, my signal is 0 bars ;/
[Galaxy S I9000 Android Development] drew071:
Have u checked ya imei? If its blank reflash the last good modem u used. If that doesn't work go back to stock from

Drew071
[Galaxy S I9000 Android Development] .:Crack:.:
Thats not true. The higher the dbm the better the signal. (keep in mind that -87 is higher than -101 e.g.)
[Galaxy S I9000 Android Development] aaron.bufc:
I only tried KF1 and had the exact same issue. Flashed back straight away as I needed to make a call. Yet to try KB3.
[Galaxy S I9000 Android Development] fuzzvirus:
Try xxkd1 and you would not have the problem. Using this for last 2 days. A daily driver
[Galaxy S I9000 Android Development] alom5:
Back to jvu. none of these are much better than jvu.....

tried kb5 and had the best reception by far....but wifi didn't work and hspda didn't work...if anyone knows how to fix that...it would be fantastico....unbelievable...
[Galaxy S I9000 Android Development] myrddral:
I've flashed KF1 and it brings the exact same results az JVT.

Rom: AOKP M4
[Galaxy S I9000 Android Development] chrisb1977:
What sort of results are people getting in the UK? I'm currently on JVR which works well for me, so don't see a need to change unless the results are noticeable.
[Galaxy S I9000 Android Development] alom5:
not worth to goto these modems. i'm in the uk also and have reverted to the following and it's fantastic.

flash it 2 times to be sure....and you will see great reception.....i got t-mobile and getting great reception at my workplace which i struggled to get any signa...

[Galaxy S I9000 Android Development] sa1yan:
I've only tested these in the U.S (Captivate) so I can't speak for the rest of the world. Some people have been saying they have been better and some have said they have been worse. Nothing wrong with trying! I will try to find the modem regions if I can...
[Galaxy S I9000 Android Development] chrisb1977:
Thanks will flash now. I'm on t mobile too.
[Galaxy S I9000 Android Development] doc_2nas:
I'm from Indonesia,Asia, uckf1 works perfect (except for capped upload). xxkb3 and xxkd1 could not return to 3g/hsdpa after I switched to 2g. Thank you
[Galaxy S I9000 Android Development] AbuYahya:
in UK. Too me the modems are very simlilar in performance except the capped one. JVT is best for battery although the signal is not as strong as some others (but only marginal difference in the latter).
[Galaxy S I9000 Android Development] Bonta768:
I am in Melb/VIC/AU. I am on Optus.

I use XXKB3 OK (still testing). I have always used the XX* series.

AUCKF1 didnt seem to get as good signal level for me.

On ICS, teamhacksung alpha build 17.
[Galaxy S I9000 Android Development] kamalmawa:
seriously people need to stop assuming that just because they have problem with one modem doesn't mean everyone else gonna have same problems. You are forgetting that provider also an major player when it comes to modems. For an example someone from Melbourne, Australia posted in this thread that he get good reception with KB3 while I can not get any signal at all with KB3 in same location but with different provider (see the post above me you see what i'm talking about).. for me KF1 saving hell of a battery for me with good reception

it takes less than 30sec to flash one of these. And 1min to download for most of you.. And you are here spending more than 5min asking the question and checking the reply. Best answer for this question would be just give it a try ;)
[Galaxy S I9000 Android Development] sa1yan:
A very well put response. Its not like you are gonna lose your apps or anything, and mileage varies per person, so if you want to know how its gonna be, TEST IT!
[Galaxy S I9000 Android Development] diablo_ger:
Test in Germany with SGS i9000, Semaphore 0.95b and AKOP Milestone 4

KF1: like JVU in 2G/3G, but no GPS

KB3: No 3G connections anymore, only 2G
[Galaxy S I9000 Android Development] alom5:
I don't think anyone is assuming anything here....the thread is for people to post their results so other people can use that info for their benefit. As you can see I posted my results and found kb5 to have best reception which is not mentioned in this thread but certain things didn't work...I didn't say it won't work for other people....but that's what it's all about posting results...so don't really need someone to have a moan about that.

Thank you.
[Galaxy S I9000 Android Development] kamalmawa:
From my understanding of English when you said "not worth goto these modems" says other wise.. sorry this is totally fault of my English teacher :D

thanks..true and true.. I saw this just after replying to a guy who posted on semaphore kernel thread that these modes will improve your signal but it will disable your 2G :eek: (true for some users) so had to say it :rolleyes:
[Galaxy S I9000 Android Development] alom5:
I just fixed my English :D

Damn these predictive things ;)
[Galaxy S I9000 Android Development] Luiwammes:
Both modems give me te same problem: Not able to make phone calls.

So for any Dutch users: These modems do not work with Telfort (KPN).

Too bad:(
[Galaxy S I9000 Android Development] asdsadas2010:
My signal bar directly goes up to 5 :D

Using KB3 in Singapore here
[Galaxy S I9000 Android Development] Luiwammes:
Erm.. your screenshot shows the results of a pretty avarage WiFi connection.
[Galaxy S I9000 Android Development] bambam1978:
Well heres the deal for the sgs users on bell canada mobile network. both of these modems work but cut in and out constantly. The kf1 when working picks up all bars and h and 3g the kb3 seems to switch by the second between h and 3g so overall for me thumbs down ill stick to the ugjl2 modem.
[Galaxy S I9000 Android Development] Marshy919:
I noticed that using kf1 and kb3 swapped me from Hsdpa:9 to edge:2. How can I fix this?
[Galaxy S I9000 Android Development] cink40:
Strange thing: after using KB3 droidwall (or any firewall) stopped working on data connection (works fine on wi-fi connection). Firewalls are not working on data connections even after i changed modem back to JVU...

Anybody can confirm firewall working on data for KB3?
[Galaxy S I9000 Android Development] asdsadas2010:
Actually i consider the results quite good since it's a shared hostel internet (600+ students) and before i tested it my friends can't even open their email using the same connection.....i've never gotten those speeds even with the comp, so yea :D
[Galaxy S I9000 Android Development] XeoNoX:
confirmed working in USA on ATT Samsung Galaxy S Captivate on MIUIv4 rom , it got me an extra 2 bars!!!!
[Galaxy S I9000 Android Development] danieleb89:
I earned about 8 dBm with KB3, not bad since I had no signal here...
[Galaxy S I9000 Android Development] sudeepm:
my experiences with Vodafone in Mumbai, India (on ICSSGS RC4.2)

JVU: pathetic download and upload speeds. Edit: Not really, stupid SpeedTest picked up some random server named "Male" and hence the pathetic speed. Repeat test showed quite comparable results with KF1 and KB3.

KF1: great download speed, upload still pathetic, only 3G connectivity, once i switched to "only 2G", i got "Emergency calls only", and then it didnt even come back to 3G

KB3: great download as well as upload speeds. Here too, got stuck with "Emergency calls only" once i switched to "only 2G". Reboots, reflash, etc didnt work. Had to reflash KF1 and then back to KB3 to get this working. Am sticking to KB3 for now, given the superb speeds. Lets see how it fares in the long run.

Edit:Only downside with KF1 and KB3 is that i cant stick to 2G network to save battery in times when i dont really need 3G speeds.
[Galaxy S I9000 Android Development] crocodylek:
I've got exactly the same experience!
[Galaxy S I9000 Android Development] XeoNoX:
wow what a jump, using KF1 modem on ATT

In Texas, no matter what I do (even KF1 -> KB3) I'm getting no signal at all with KB3.

KF1 is working. Seems more reliable, but very inconsistant speed wise.

According to this page, UC version modem is 850 mhz.
[Galaxy S I9000 Android Development] kamalmawa:
Also tesltra Australia has a 850mhz version of nexus s if someone can find it..
[Galaxy S I9000 Android Development] sa1yan:
I have tried many of the other radios from the nexus s thread, but I've only got these 2 to work. Idk why. Anyone else have different results?
[Galaxy S I9000 Android Development] omnicronx:
I've tried every modem, even the ones that Nexus users confirmed were 850 native..

Not a single one worked when manually setting too 850 (though many of them work great on the 1900mhz band)..

It may say 850 is selected (in fact it does so by default on a few of the UC versions), but it will never actually switch too it ..

yup, also xxkd1

I am on 4.0.3 TEAM ICSSGS 4.2 with JVU modem. I live in Spain.

I flashed both modems: Signal amazing. 3G faster. GPS is good, but don't notice any difference. Calls working.

I don't feel difference between both modems. I will test it with Speed Test later.
[Galaxy S I9000 Android Development] addicted2088:
I don't think flashing the modem.zip is required. simply copying the modem.bin to /modem is enough on MTD ROMs..
[Galaxy S I9000 Android Development] chrisb1977:
After trying KF1 and KB3 I found them both had faster data than JVx, unfortunately the call quality on both modems was very poor. The callers voices sounded very robotic and distorted and I couldn't understand a word they were saying. I have settled on using JVU.

I am in the UK on T Mobile (and sharing Orange network) .
[Galaxy S I9000 Android Development] Proelio:
is radio related to the wifi signal or wifi download speed?
[Galaxy S I9000 Android Development] -ReaL-:
No, no and no!

Ok. Thanks :)
[Galaxy S I9000 Android Development] insanedreamz:
What about the calls? Are they clear?

I'm using JVT modem on BSNL, and I get 2 bars max and calls hangs when 3g goes zero. I'm on CM9.
[Galaxy S I9000 Android Development] sa1yan:
Calls are probably the best part of this modem. They greatly improve quality.

Thumbs up...

Just flashed kb3 radio, and seems to work ok.

Im on ICS, with kpn provider.

Edit : calls arn't working... Like posted before.... Had to try:D

Thanks man
[Galaxy S I9000 Android Development] combatdeity:
Flashed KF1, calls aren't working, lots of staticy noise. Any one have any ideas what's up with it? Texts work fine, and 3g and download speed are greatly increased.

In the UK on orange.
[Galaxy S I9000 Android Development] Danh2009:
Same here only im running KB3 and on the Three network (which is part of the same network).

im running Slim ICS 2.9, and I usually have issues with signal in my home, i now actually have 1~2 bars of signal but cant make phone calls, but i can confirm 3g/H download speeds are excellent!

might roll back to KF1 and post results.

EDIT: rolled back to KF1, seems to work for a little bit longer, call quality is awful its very choppy and has a lot of static.

I have found that after a few seconds of being in call you lose the call and then after that you can no longer make any more calls.

Any ideas??
[Galaxy S I9000 Android Development] -Loom-:
I'm using AOKP Build 28, on German Vodafone network.

Initially used JVU modem, and from there upgraded to KB3. I got no HSDPA signal.

Then I tried KF1. It worked but the connection wasn't better then JVU.

I flashed back to JVU, then KF1, and after a reboot KB3 - this time it worked, and reception is noticably better. From my first tries the call quality is as good if not better then JVU. And the data speed is downright brilliant.

Verdict: If you cannot get KB3 to work, flash KF1, reboot, then KB3 afterwards.
[Galaxy S I9000 Android Development] Rubysz:
I'm from Israel on Cellcom.

Tried them both. Had horrible reception. (Compared to JV6/JVU)

(Any other cellcom users around with a recommendation, by any chance?)
[Galaxy S I9000 Android Development] topp10:
I'm in the UK on Vodafone normally on JVU.

All of the modems work for me.

KF1 was the worst (slowest data speeds).

KB3 was the fastest download speed but slower upload (compared to JVU).

JVU was fastest upload and only slightly slower download speed (compared to KB3).

Calls were fine on all 3 (I don't make that many calls).

I've remained on KB3 because of the slightly faster download speed...
[Galaxy S I9000 Android Development] tanivula:
Love these nexus modems! Only trouble is that 2g doesn't get me anywhere. On 3g it finds both my network (2degrees) and vodafone but when switched to 2g it only finds vodafone leaving me with no access!

Still amazed how seamless the umts - hsxpa works and how quickly Wi-Fi connects. Haven't really noticed any difference in call quality (no thorough testing).
[Galaxy S I9000 Android Development] Perka:
I did not get a better result with Nexus s modem on my sgs1,

pls check my tweets for testing log.

Glad it works for some :)
[Galaxy S I9000 Android Development] blakrepublic:
This might sound dumb but does this work on the nexus s 4g
[Galaxy S I9000 Android Development] sa1yan:
Haha, this won't. Go to the nexus s 4g thread, and look for radios and how to install them. I believe you have to use "fastboot" and our phones don't use that..
[Galaxy S I9000 Android Development] mygmy:
Any middle east users tried this with umts 2100 and gsm 900 and 1800?
[Galaxy S I9000 Android Development] mmjuban:
i've installed KB3 several days ago and it working great here in Vietnam! Aside from the faster download speeds, the battery life seems to have almost doubled! I think this modem is much more conservative when switching between networks and not wasting too much time trying to connect to very weak signals which is great coz the 3G signal here is quite spotty. Thanks so much for sharing this! I can hold off buying a new phone for a while longer (i'm itching to know what the SGS 3 will come out to be, right now I'm eyeing the HTC One S)
[Galaxy S I9000 Android Development] sa1yan:
I'm glad it work fine! Trying to squeeze out as much as our phones can handle here :P

Hi,

KB3 for me I can't switch to 2G.. I can but left on Emergency mode!
[Galaxy S I9000 Android Development] alom5:
I have tried again the modems...and kf1 has amazing download speeds...but Call clarity is lacking...kb3 got no signal over and over...then replaced modem.bin from jvu and the results are a follows.....
[Galaxy S I9000 Android Development] sa1yan:
I had the same problem. Maybe try KF1?

Those are pretty decent speeds. I guess it all depends on each particular individual. I've had a good experience, though I'm off AOSP roms so I've gotta stick with my AT&T crap :/
[Galaxy S I9000 Android Development] misterpro:
Tried both. KF1 signal is the Same as JVU. KB3 signal is a little bit better.

Both modems are slower than JVU for me though. (JVU 2 or 3 times faster download speed.) At least that's how it is for me here in Belgium (Proximus)

Thanks for sharing anyway.
[Galaxy S I9000 Android Development] sa1yan:
I have found that wiping cache before flashing the KF1 does wonders. In case anyone else is having problems..
[Galaxy S I9000 Android Development] lohho:
I guess that does not include 2g?
[Galaxy S I9000 Android Development] misterpro:
That indeed made them perform better. Thanks.

Sadly KB3 is still slower than JVU or KF1 (they are both the same regarding download speeds now, and KF1 is probably better for battery considering it swaps back to 3G when connection isn't used). I would very much want to stick with KF1 if upload wasn't capped so horribly low... I tried flashing XXKF1 instead of UCKF1 but somehow that radio doesn't work with our I9000's...

So still... Back to JVU (sadly)
[Galaxy S I9000 Android Development] nemanja066:
KF1 -All works fine (calls, mms/sms, 2G (EDGE)/3G(H)), voice in calls is a little louder

KB3 - All works fine unless 3G, quality of voice in calls is same at JVU

I am using KF1! :D

[Galaxy S I9000 Android Development] NXJeff:
For those who said modem doesn't related to the Wi-Fi signal strength

I want to make a correction.

It DOES affect the WiFi signal.

This modem have a slower/longer latency compared to other modem.

doesn't impact for normal user but if you use some application that remoting a PC or wat. you'll see the significant lag.

switch back to JVU everything seems okay now.
