using kf1 on my gummy rom.

I was using JVT or JVU before and getting 3g/hsdpa download speeds of up to 62 kb.

now with KF1 I am getting 122 kb download and 107 upload! that is amazing, I've tested locally here multiple times and never got anything like that.

and this is in my house, where I usually only get Edge and not even hsdpa.

thanks!

rom CM9 build 17 operator 3 ita:

jvu--> -85dbm

kf1--> -73/-81 dbm

I think it's really good ;)

nation: italy

rom: cm9 built 17 + lernel devil 1.1.6

modem: KF1

Installed and all works now i test for some hours/days to see if it's better of jvt/jvu...

thanks all :eek:

ps: after this test i try other modem :p

edit: 1st impression is that with tim italy the 3G download (HSDPA) is more stable and fast before with jvt/jvu the connection comes and goes ( :-) )

I use KB3 in Lithuania, Omnitel and now i get 3 bars Hsdpa (JVU was only 2).

Signal strength -97 dBi

Here is my speedtest results
[Galaxy S I9000 Android Development] BenjaminX2:
I'm on Codename Android 1.5.5. I'm from the Netherlands and use the Vodafone net.

I tried the 2 modems and the KB3 rules, data and phone connection are super! When trying the KF1, I recieved a message from Vodafone that they would alter my settings, because I had no data connection. They did within 1 min and I performed the speed test.

Results are in the image.
[Galaxy S I9000 Android Development] Funnnny:
Just tested KF1 and KB3.

with JVU and KF1: signal is between -71-83

with KB3: -81-87

Will test again when I arrive at home (pretty bad 3G signal in my room)
[Galaxy S I9000 Android Development] mammenj:
Thanks, just flashed KF1 on THS b17 ICS (hyderabad, India)....will report back after at least 1 day of use.

KF1 is not good for me. wifi speed is not stable. 3G is good

KB3 is "very good" for me. 3G＆WIFI is both nearly perfect:D

I come from Taiwan. 3.5G download 400-430Kb/s at outdoor.
[Galaxy S I9000 Android Development] Solictice:
That looks promising, I'm also on Vodafone and from NL.

Going to try both and see if I get the same results as you.

Kb3 works but you must flash kf1 first and then Kb3, tested on Vodafone Portugal.

Great clarity sound calls and short ping and getting good data speeds, testing GPS.

[Galaxy S I9000 Android Development] sepu79:
have anybody tested these modems in finland?
[Galaxy S I9000 Android Development] jacobuscuracao:
tried KB 3 also in Curacao (900 band, like Netherlands) but KF1 is definitely much faster in download:

KF1 was 122kb download and KB3 only 63 kb (same as JVU)

so I'm staying with KF1, amazing performance!

when I installed KF1 back I got 'no service' for 5 minutes or so, but then it was OK, switched back between H and 3G a couple of times.

later tests weren't as stunning as before - last one was also 63 kb download with 192 kb upload, but still overall faster than K3 and JVU.

[Galaxy S I9000 Android Development] pbecks1963:
I am also on vodaphone (netherlands) and couldn't get kb3 to work (no mobile provider to be found) I followed the instructions in post #1 to the letter. KF1 does works however. I also (the first time i flashed kf1) reveived a message from vodaphone (ignored it), kf1 worked right away...
[Galaxy S I9000 Android Development] Alf55:
You're right, works now! wich one did you choose to use? i would like to try the diferent one for posting later differents feed backs. thanks
[Galaxy S I9000 Android Development] rtoussaint:
Tried KF1 first. Jumped from three to five bars. KB3 didn't work for me, even after flashing KF1 first and rebooting before flashing KF1.

Flashed KF1 again, but now I have horrible results on WiFi. 1800ms ping for example. Will try again when I'm at home.
[Galaxy S I9000 Android Development] Zimbilik:
I had a weird problem. I flashed KF-1 over JVU.

I received a call from my bank. I had no problems. But after that I tried to call my brother and I couldn't hear him nor could he hear me. I tried like 5 times but it was the same result. I rebooted. Called my GF and it was crystal clear. After that call I called my brother again immediately but again got no voice transfer at all. I could see the phone was answered because the timer started.

Telus

I tried KF1 on Telus. Data speeds decreased and Cell signal was flaky.

KB3 didn't work for me, and I flashed it after KF1 as some people suggested.

So I went back to trusty UGKG3.

I wouldn't mind trying KD1 if someone can create a cwm package.

Also, I couldn't figure out how to tell what band I was on. The secret samsung codes don't seem to work on CM9.

I'm with original 2.3.6 JVU ROM (with Semaphore 2.5.0) and can't understand how exactly to flash that radio ? Can somebody help me, because I don't want to brick my phone. What I did so far is to download the 2 .zip files, but when I try to flash them with CWM I got error message.

The second I can try is to copy modem.bin in MODEM_I9000XXJVU_REV_00_CL1092175.tar.md5 (original modem for JVU), but I don't know which archivator program to use (WinRar don't support .tar for overwriting) and after that to flash with ODIN. But I'm affraid if that don't succeed, I'll brick the phone.

So how to flash that radio, thank's. :)
[Galaxy S I9000 Android Development] loco-:
These modems are for CM7/MIUI/ICS-based roms only. Don't try it with your stock rom.
[Galaxy S I9000 Android Development] omnicronx:
I have to go check to see whether its flipping bands, but on KB3 when I go into debug service menu it has 2100/1900/850 selected from the WCDMA Band list by default.(so it appears that it is supported)

Download speeds definitely seem to have increased but.. I need to do a proper comparison on reception and download speeds from a place not in the very middle of a building :)

Also should need to probably check that fallback is working...

This is on my Bell SGS using CM9 ALPHA build 17..
[Galaxy S I9000 Android Development] Funnnny:
You can't brick your phone if you only flash the modem, go on and try it, I even flashed the kernel.tar to modem section and still can boot into the ROM (but of course no service)

bTW, great success with KF1, I can have 2 bar signal in my room and have 3G connection (my room have very poor 3G signal before)

[Galaxy S I9000 Android Development] siky_dude:
ohh god... you don`t flash the whole package, the the modem.bin and just flash it with odin.. or replace it in a CWM3 modem... simple as that.

read the stickies before posting :)
[Galaxy S I9000 Android Development] tihomirone:
Yes, I flashed the .bin file and the phone doesn't start anymore.

P.S. Very strange. I did it again and it works ...
[Galaxy S I9000 Android Development] siky_dude:
if you flashed it in the pit file.. yes, that will happen.. but that is a bit moronic and has a chance of happening of 1.000.000 to 1.

a modem can`t impair a phone to the verge of you not being able to start it anymore...

you did something wrong.
[Galaxy S I9000 Android Development] rajeshbabushrestha:
flashed KF1 few hrs ago n i can confirm that call quality is jus awesome n 2g n 3g works better than jvt but less sats n takes lot of time for fix (7-8 sats) in gpstest plus compared to jvt (min 10-11 sats) in my place... can anyone let me know regarding gps fix in their region... anyways great modem for galaxy s... thankx

carrier: etisalat egypt

1st flash

I flashed kf1:

-tried umts, hsdpa, 2g=ok

-signal not that strong, weaker than on previous modem (jxjv6)

-i tried call someone, no ringback, call ended in a sec or so.

2nd flash

kb3:

-didn't test umts,hsdpa or 3g

-signal not that strong, inconsistent at times, about the same like kf1.

-tried calling=same behaviour like kf1.

back to jxjv6:

-call working.

nexus s is never officially launched in egypt, maybe that's why those modems/radios doesn't work. or does anyone have any other explanation(s)?
[Galaxy S I9000 Android Development] siky_dude:
have you used fasterfix?...

if yes and still no change, then this modem is not for you if you are that dependant on GPS :).

EDIT: what annoys me is everyone is leaving feedback and stuff... but on the stock modems they didn`t give a s**t about helping other users...

i`m curious,why is that?
[Galaxy S I9000 Android Development] rajeshbabushrestha:
actually i havent... lol... anyways i might as well go back to jvt soon... thank u for ur awesome modem collection :P

Edit: regarding the 2nd part... in my opinion after some time people start taking things for granted.... mayb because of that they only care abt what bothers them n people who actually value the essence of helping others decline... dont b mad bro coz there are still many who like to help others n will be there forever... jus love this community :)
[Galaxy S I9000 Android Development] tihomirone:
Ok, I flashed the both radios, but the reception get worse than the original JVU radio in Bulgaria (Vivacom). In fact the original radio is working fine - gps lock within 5-10seconds, very good Wi-Fi ... so may be the improvement is only in CM builds .
[Galaxy S I9000 Android Development] siky_dude:
MODEM has nothing to do with wifi :)

and no, not only on cm builds.. maybe it wasn`t built for your country... but i got a serious battery boost after using kf1 :)

850mhz band

Doesnt look like the 850 band works for either modem. It shows up under band selection, but any attempt to only use 850 does not work. While it does work on KG3 (bell modem).
[Galaxy S I9000 Android Development] cba1986:
I use the 850 band and both modems works great. At first flash KB3 didn''t work i went back to JF1 and it worked.

Try this.

[Galaxy S I9000 Android Development] boarder.2k9:
Not entirely true, if your phone runs out of battery during the first boot there is some major balls up (technical term) and you will lose data connection no matter what you do. Even using USB jig and starting again with flashing has no effect. Off topic but make sure you have more than say 5% battery before you flash (i forgot to check).
[Galaxy S I9000 Android Development] cba1986:
Maybe it would be a good idea to the people who is having problems to dial

*#*#4636#*#*

and choose and choose between modes.

I was having problem with KB3 because it was loosing signal all the time. The problem was that the was toggling constantly between networks modes. When i chose GSM only, the problem was gone.
[Galaxy S I9000 Android Development] omnicronx:
What do you mean by use? Do you exclusively use the 850 band? Or are you like me (bell user) where 850 and 1900 are used in conjunction.

Both modems work fine, but they only seem to support 1900 (if you go into debug it actually shows that it has 850 support by default, but it does not seem to work). If I deselect every band in debug mode and only chose 850, it does not pick up a signal. (where i know there is one, and works perfectly fine on KG3)

I went KG3 -> JF1 ->KB3 and I certainly see the improvement, but I also certainly lose the 850 band which sucks for people like me who work in the very middle of a building =X

I may try going from JVT like you suggest, see if it does anything..

---------- Post added at 08:42 PM ---------- Previous post was at 08:36 PM ----------

This is what I notice.. when I flash to KF1, auto band selection mode is selected and all the right GSM/WCDMA modes are selected.

Once I flash KB3, only WDCDMA modes (abeit the correct ones) are selected.

Now I have an i9000m so this may not be the same as everyone, but KB3 seems to deselect all GSM modes by default. This be the reason that some people can't get 2G on KB3, but they can on KF1..
[Galaxy S I9000 Android Development] belmethos:
i have installed kf1 modem to running dark knight 3 with devils 1.1.6 cfs. Yes the calls sound better but battery consumption went thru the roof, also after few calls in succession i can make calls but i cant hear anything, opposite side also cant hear anything.

[Galaxy S I9000 Android Development] ausduckz:
Currently trialing KF1 in Victoria/Australia on MIUI Android v2.3.9 using Glitch Kernel v13.1.

Will report back usage in a week or so, once I've had a chance to recalibrate the battery etc.
[Galaxy S I9000 Android Development] edgarpoe:
same (bell mobility) here with kf1, sounds nice for calls but pulled my battery down like crazy!! Other modem gave me no service at all.
[Galaxy S I9000 Android Development] omnicronx:
As noted in the OP, you have to flash kf1 first then KB3 or it will not work. KF1 has terrible reception from what I've tested on my bell SGS, so its not surprising you are getting bad battery life. KB3 on the otherhand seems to have the best reception I've seen..

Only problem is neither one seem to support the 850 band regardless if it says its selected or not. I never saw it switch over once on my 40 min trip home, and when you force it to 850 only it does not work at all.

In other words, neither of these modems seem a good choice for bell users.. (unless I'm completely missing something)

You may also lose the 850 band if you switch back and have to add it manually depending on what radio you were using.. KG3 did not automatically select 850 when I switched back, but KC1 did..
[Galaxy S I9000 Android Development] cba1986:
I use exclusively the 850 band as i use only the gsm band. i forced to use only the 850 band and all is good.

Remember that most modem are regional it may not work for anyone.
[Galaxy S I9000 Android Development] sa1yan:
I am in US, and find that the KB3 is a brilliant modem. I've left it sitting idle with Wifi on and its drained only 4% in 12 hours (I went camping). This is with around a constant 3-4 bars of signal though. But I'm sticking with KB3. These modems can be weird in terms of getting service, I had to like flash it 3 times in order to get it to work. Idk, you just gotta play with it or do a flash from a fresh ROM flash. Good luck!

Second KB3 on top u can see H ... not switching to 3G and has a nice down/upload rate ... switching from 3G to 2G doesnt work... there is no no way back from 2G to 3G only flashing modem once again....

I dont know what happend if i chosse wdmca only and i am not in range to have 3G or H signal ... while i look today what happend ...

The tests yesterday are from KF1 or KB3 previous from JVK or JVT i dont know exactly ....

I have tried all possible ways of getting into the menu, but nothing worked, after I dialed the menu code numbers, they just disappears from the dial window and nothing happened. I want to set the band to select 850 only, and not switching between 1900 and 850.

I live in Thailand and I do not have 3G but this is definitely the best call sound quality I have had. Also the calls seem faster, hard to explain but there seems to be no setup time, you hit the call button and it rings instantly almost.
