So I was on the latest gingerbread release and was having awesome service where I'm from, even at my girlfriends house in the country. O went back to stock froyo and was wondering if I could flash that modem to froyo? I've flashed modems on this phone before, but am not sure if that modem is compatible with froyo. Would it harm my phone?

As long as it's an I897 modem you're fine. An I9000 modem will give you sound issues on calls.

hey guys , i have flashed several rom and i really like the look and feel of the darky's rom however i have really bad reception issue. sometimes at home where i usually have full bar i have no signals at all , or last night i was traveling to Oklahoma city with my friend who is running captivate on stock rom and he had full bar while i had no service at all ! any idea what i'm doing wrong ?
Usually better to ask in the darky thread , but anyways.
Did you flash back to stock and then upgrade to darkys or did you upgrade on top of a previous rom? If the latter, flash back to stock and reinstall.
If the former, try a different modem. I am not using the modem or kernel that came with darkys rom. I am using the kernel with speedmod and ugjl2 modem and so far I have great reception. Of course that isn't saying much as I always have great reception using my cell device (can't think of its name atm.)

You are running the I9000 version and not the captivate port. This alone wont cause problems if you have the reoriented kernel but the jpy modem you have will. I believe it does not have the 850 band. Flash a different modem from the modem thread in the development section and you should be good to go.
If im mistaken please forgive as its 7:30am and I still haven't slept yet.

thanks for your reply ! well yea i did one click odin to stock 2.1 and then flash this using this guide http://forum.xda-developers.com/showthread.php?t=868262
and http://forum.xda-developers.com/showthread.php?t=808286 flashing xcaliburinhand's latest reoriented kernel (odin version) with voodoo (I9000_reoriented_v2.3.0) so i'm not sure what is the issue here ... can you all guide me what modem should i use ? i was actually thinking about the same thing because i use to have a phone that didn't have 850 bad and i had this kind of issue ! so any help of how and where to get a modem to flash will be greatly appreciated !
I personally use JK4. A lot of people find that JL3 works better for them. Either way at the moment these are the top two modems available. Both can be found here http://forum.xda-developers.com/showpost.php?p=9134296&postcount=2 and are flashable via CWM.
Also next time you are going to flash a version of Darky's just use this thread http://forum.xda-developers.com/showthread.php?t=890429 or any one that ytt3r starts because he ports them over to the captivate and you don't have to worry about messing with kernels or anything not working properly.
thanks i'll try it next week , since i'm running Axura 2.2 and so far i like it
Hi I was wondering if any bell or more appropriately Sasktel users are using any gingerbread roms and how the csc and modem is working out.
Sent from my Iphone killing I9000
I'm on Bell, used to run CyanogenMod7, now I'm testing out the latest MIUI gingerbread builds. The modem seems to work fine enough (either JL2 or KC1). I haven't had any issues. Battery efficiency could be better, but I'm not convinced that's the modem's fault.
So other than battery probs are you happy. Also all you did is flash the rom and then a new modem

Yeah, I'm on Rogers with CM7 and KC1 Modem, running smooth with great speeds on my 3g+ I just noticed your other post and yes I flashed the ROM and then the Canadian modem
Hi i have a question about allowing the hspa network on stock froyo rom....
How would i go about doing this?
Flash a new modem? Possible one from an hspa capible device like the i9000?

Would i also have to use an i9000 kernel or could i use my current existz voodoo kernel?

Kernels have to match modems. kb1 to kb1, i9000 to i9000.
So is running a i9000 kernal better than using a captivate kernal?
if so what are the pros and cons if any?
rom kernal match
Look. I've tried different kernals with stock froyo 2.2 and learned the hard way with sticking with stock modem. Call quality was crap and battery life severly dimished with having a improper mix of modems and kernals. Since those mistakes I run continuum 4 with onix kernal 2.05 and jvk modem and have great batt life and call quality and download speeds are phenomenal. The best way I have found without going flash crazy is to see what the experienced people are using on their phones. The have it listed in their stats at the bottom of each posting they make. These people have been modding for awhile and know by experience what works best. Try that and you should have no problems getting the best combo for your captivate. Hope this answers your question. Good luck!
hsupa is over rated the phone already has hsdpa. hsupa may be good if you want to video chat or teather. but if you must get hspa in full you want to flash a different rom. no one has figured out a workaround for the brokn bluetooth calling with a rom/modem mismatch on a north american captivate rom.
as for the kernel, well i haven't tried an i9000 or i9010 or i9088 kernel on kb1 but they all should work. also i haven't tried changing the modem without changing the kernel but i believe that should also work. even if it is not recomended. i have never adhered to the notion that modems and kernels should match and had good luck with modems for t959d i9000m and i9088 on i9000 i9010 and i9088 kernels without major problems. it does seem that the older modems do not work all that great on the captivate with call volume or quality problems regardless of rom and kernel. but the kp1 from i9088 and kc1 from i9000 are both great on the captivate, i think i give kc1 the edge. if it weren't for those two and maybe others that i didn't try i would recomend leaving it all kb1 for the simple fact that a phone should make good phone calls.
the adage that the modem and kernel must match is true. ie. i9000 kernel/i9000 modem i897 kernel/i897 modem....it is absolutely true you must match those. if you use an i897 modem with an i9000 kernel or vice versa, you will have data but no voice. its not just a myth
Quick question, can I use i897 modem and kernel on an i9000 rom?
Just curious.

This actually seems logically possible.
If we can use a reoriented i9000 kernel + i9000 modem on a captivate rom, why can't we use a matching captivate modem+ kernel on an i9000 rom?
I thought the important thing is to match the modem and kernel...

You're right. As long as they match it's fine.
Well experimentation if the spice of life.

Well, accidentally I ended with this configuration:
ROM: Apex 9.2 (JVR)
KERNEL: Talon 4.4.22 (JVR)
MODEM: KH3
Teoretically this shouldnt be happening but everything seems to be working O.K. No Force Closes, WCDMA 850, average battery life, WiFi, etc.

you have always been able to run mix/match, until you need to make an actual phone call. no voice.

Yes I ran that combo until I got a phone call and the other person could not hear me and the volume was cutting in and out flashed back to JL2 all is good again
Running Dlevs 5.0, and latest talon kernel, modem JL2
As you can see from my signature I am still running 2.2 ROMs. I just prefer the stability, and have zero issues with both that I am using now on different captivates. One of them, Continuum 4.1 is and i9000 rom, using Onyx kernel with jk4, the other is the i897 Cognition, cog kernel, kb1.
I think, based on what I am reading here, I will try to intall the i897 modem and kernel on the Continuum 4.1 ROM. I really like this ROM but REALLY prefer the sound quality of the i897 roms because of the Audience chip.
I will experiment this weekend and report back. As of now, I prefer not to do this kind of experimentation with the GB roms. Anyone else interested in seeing how this turns out?

Hi Jack man,
if you are still considering flashing i897 kernel & modem , my captivate is still Froyo 2.2 stock (rooted), with the uckb2 modem and kernel 2.6.32.9. I already have a dump of the kernel (I checked is working) and could send you a dump of the uckb2 modem (unchecked, I'm unsure about flashing this one back, since I have the 100% battery shutdown issue and still considering a RMA) if you are willing to try.
Let me know,
Angel
Well, I experimented. Here's what I used and how it went.
I installed Continuum 4.1 (a froyo 2.2 rom) then flashed the Exist kb1 kernel along with the kb1 modem. I thought everything was going to be fine. Calls worked fine, data seemed ok but slower than I was expecting, but when I went to turn on wifi if just didn't work. I made sure it was't the router - my wife's phone was working fine on the router, along with a laptop on it.
it would also not connect to the neighbor's router either. Flashed back to Cog4.5.3 - wifi worked fine.
Too bad, because I really like the small features of Continuum 4.1
If anyone has any ideas to fix the wifi in this setup let me know. I would love to keep it.
I am new to Galaxy S but have had experience with roms, kernels and radios from a G1.
I started with Samsung 2.2 firmware and rooted it using Cyanogenmod wiki page and flashed the latest MIUI. I know kernels change speed and include Voodoo colours and sound for Galaxy S. I also now radios can change signal and gps accuracy.
1)Are modems the same as radios and if so where do I find a list of them?
2)What is the best bootloader and why does the Gingerbread one not have sd cards work? Also what else doesn't work?
3)How can I check which radio I have and if I flash any bootloaders how do I check that?
Radio, Modem and Baseband are all the same thing. You can check which one you have by going to Settings >About Phone and checking the Baseband Version.
A new modem is easy to flash as a zip file from Recovery and you can find lots of them by searching in the Dev forum, however make sure you flash a modem that is for CM7 since you have Miui installed. For guidence you can search for Modem in the Miui or CM7 thread in the Dev forum.
As for bootloader, there is no way to check which you have, but as you installed Miui directly over 2.2 you should have the froyo bootloaders. CM7 and Miui were designed for froyo bootloaders. Some people say that GB bootloaders have better battery life but if you have GB bootloaders with CM7 you can't access you external SD card and other things may not work properly. I would suggest staying with froyo loaders for now and seeing how it goes.

I have read this:
http://forum.xda-developers.com/showpost.php?p=9579987&postcount=11945
but I don't know if it still JPP is the best radio as this was back in December. For people in the UK what would be the best overall radio?
can anyone answer me which is the best CM7 modem for ORANGE ROMANIA? tks
Try jvp or jpy, I'm on orange uk, insanity cm and they both work fine for me don't forget you need cm7 modem, there are 2 threads in dev for this

About bootloaders
I have a SGS GT-I9000, and following
directions from ROM kitchen, I installed a Froyo 2.2.1 version.
It's I9000XXJPY with 2.6.32.9 [email protected] #22 kernel
and it says Rom kitchen v11.1-ZSJPK.
I wanted to install a Gingerbread version from ROM kitchen as well, but it says I have to make sure I have at least JVH bootloaders. Ummm, do I ? And what to do so i could install a gingerbread to my SGS ?
I installed a 2.2.1 froyo also from ROM kitchen I9000XXJVO with 2.6.32.9 [email protected] #22, build number XWJSD, hoping i'll install newer bootloaders with it.
But, i had problems with messaging so i'm gonna have to revert to previous one.
Do i have proper bootloaders or not and what could happen if i tried to install Gingerbread and don't have proper bootloaders.
Thanks in advance
