Has anyone tried the other modems to work with the stock froyo to see if they work better?
Not tried any myself since flashing KB1, but when on JJ4, trying any non AT&T Froyo modem.bin would result in a loss of sound during voice calls. HSUPA however would work under such a condition. Too bad I need this device to work as a phone first. To get a non AT&T modem, you needed to go with a non AT&T kernel, and then bluetooth voice would be static, so you also need a non AT&T framework. With a native ROM, you are pretty much HSDPA only, unless someone figures out how to patch in necessary code to enable the required handshaking.
I tried some other modems, but none had working sound in phone calls. You might be able to get vibrant modems to work, but then you'd lose 3g
When I was first working on HSUPA for the Captivate, I found that no alternate modem worked properly on the Captivate software. I believe this is due to the code being "wired up" a little differently. Every alternate modem lacked sound in phone calls and the only way around this was to use an I9000 (or Vibrant, etc) ROM with a matching modem. I think everyone stopped trying to find out exactly why the other modems don't work with Captivate ROMs once it reoriented kernels solved any issues we had with running I9000 ROMs on the Captivate. It was just a lot easier to use an I9000 ROM with an I9000 modem.
What we need is some kind of spreadsheet with ROMs down the side and modems across the top, and 3 different symbols representing Data, Voice, and GPS. You would colour each one RED, YELLOW or GREEN depending on how well it performed at that task on a given ROM.

I'm just wondering if someone can list any ROMs or flashing methods/guides that work on Bell I9000M phones without losing the 850mhz band.
I'd really like to give Tayutama's SuperLite version a go (for example), but I need the 850mhz band; is it safe? If not is there something we can do to re-enable it without going back to a stock ROM?
I've looked around the forum and not seen any clear answer to this.
Input is appreciated!
I second this.. But im thinking ill be disappointed as ive read a few places that the bell galaxy s cant be flashed with the i9000 roms out there without minor to major issues
i believe if you flash only the pda and leave jh2 modem and jh2 csc. you can flash any of the newer roms 2.1 eclair.. but havent tried it myself.. my one exerience with jm7 when i didnt do this and only kept the csc i lost my 850 mhz.

Does it have to be Eclair ROMs only?
I just spent the night trying various ones and got squat. I did find this post here (forum.xda-developers.com/showpost.php?p=8299301&postcount=18) but it seems to be older and references the JH2 files, and not necessarily a specific ROM.
If I find one that works, I'll post it here.
For now, I'm heading back down to 2.1 stock version (ugh).
http://lmgtfy.com/?q=site:+xda-developers.com+"i9000m"+froyo
I would also like to know as well... I am quite interested in trying Darky's Froyo rom
(Apparently it is safe, will probably give it a shot today at some point)
if you flash only the pda of a rom, and the jh2 modem/csc files, know that you may experience battery drain issues because they do not match. i flashed jpk with jh2 modem/csc for few days and the battery drain was insane. only fix was to flash the full jpk, then re-enable all the bands.
Would love to get an answer for this as well.
Phone crashed on first day from the store. Touchwiz issue had to wipe. So i dont see the down side to flashing when the stock can crash too.
And no gps which is such a letdown. Cant lock location ever.

Okay here are some straight facts - you can flash any of the new roms on a Bell SGS. You need the Bell version of the modem to maintain 850 - it works with 2.2 - it may or may not not be fully optimized for 2.2 but it works just as well as it does on 2.1. It just doesn't matter that much in the grans scheme of things.
All other so-called issues with battery drain, SD card, bricking, weird behavour, etc. are not caused by the ROMs either but rather the execution of underlying apps - usually optimization and timing related issues - if you have a problem it is most likely software related - i.e the app has not been optimized under FROYO.
Seriously, this is not rocket science. You cannot permanently brick your phone from FROYO - it is impossible.
If you want to successfully implement Froyo but are skeptical, pick a ROM, flash the Bell modem and then try it out for a week or two BEFORE dumping a bunch of new apps on it. Then decide if you want to keep it - which you will. Then start finding apps that are Froyo optimized and you will have no issues. Seriously.

I didn't flash a bell specific modem. I used the one that came packaged in Docs JPM froyo. Works perfect with no loss of any 850mhz 3G band.
Good job and clarification - as long as the modem supports 850 it does not need to be Bell.
First off for those that think you have WCDMA 850 working after a rom flash designed for another region, make sure you actually try and run only the WCDMA 850 band to see if you actually have it. If your not running on Bell and your network doesn't have WCDMA 850 available to you then you can't check and it won't matter. Any rom designed for a region that doesn't use WCDMA 850 will not give you WCDMA 850 and why should it.
Install whatever rom you want and simply flash your JH2 modem to get your WCDMA 850 back. After the modem flash make sure you put your phone into automatic mode and select all to refresh the modem band availability.
If your able to flash your modem AND your csc you might even get your product code back.... maybe.
For Bell users it would be nice to have a Froyo modem that will support WCDMA 1900 and 850. The 2.1 JH2 works fine though with Froyo.

Are you sure that you have the WCDMA 850 band functional with the JPM modem? Didn't work for me. Are you on Bell's network?
So is there a way to get the gps working? I can wait on Froyo but the GPS issue is terrible. Also any way to do a true backup of the phone. like an image.

Can someone confirm whether there is or is not a GPS fix for I9000M for Bell?

No, im not on bells network. I am on rogers network. Rogers in my area only has 850mhz 3G in this area. I have 3G service and in service mode it says WCDMA 850 Band 5. It works. Its also working on the girlfriends.
Version info:
PDA: i9000XWJP6
PHONE: I9000XXJPM
CSC: I9000XEEJP4
Build: 2010.10
As for the GPS its a bit better but still sucks.
I've never had a GPS problem so I can't tell you if its an issue with the hardware/software/location/interference, etc. Since day 1 (three months ago) I have had no issues locking satellites to 10m accuracy, regardless of firmware. Actually the only time I had an issue was on Osoyoos lake but I suspect that may have had more to do with the proximity to the border crossing.

Getting a fix isn't the issue. Its active tracking.
Active tracking has been a-o-k the whole time as well which I thought was implied by using the "locking to 10m accuracy" terminology.
I have been doing enough hacking of my Captivate, I got 2.2, rooted it, installed tons of stuff (most of witch I am sure I do not need)
but anyways, any quick hack to get HSPA on my Captivate, with a update.zip or something. also, I read that sometimes BlueTooth stops working right, I use it a lot so thats not an option
Ideas?
thanks
captivate roms dont show an "H" but hsdpa is enabled. hsupa on the other hand need an i-9000 or vibrant modem.bin and for some inexplicable reason breaks bluetooth audio but not bluetooth connectivity. bluetooth file transfers work and pairing works on all devices but the audio comes through messed up. if you dont like it get a sim unlocked vibrant or an i9000. the devs are still looking for a solution as far as i know but i may not be up to speed in that area. now there are many modem.bin files and kernels for the i9000 and vibrant have been modded to work on the captivate in both eclair and froyo so there may be a working combo that i just dont know about.

congratulations, you have just asked what everyone has been asking for months now.....
as of right now, if you want HSUPA (we already have HSDPA), you will lose some Bluetooth capabilities....its a fact and there are lots of devs working on making it work right....unless you can code, i would suggest you just read the dev forums and wait for a proper kernel/rom combo to become available for you to use.
Alright guys, here's my problem:
When I first got my phone, I had excellent cell reception and all my calling features worked, i.e. bluetooth calling in particular. But this was on JF6/JH7 STOCK.
I will not go back to stock, I just love my custom ROM too much. But the problem I have is that I've lost my bluetooth usability and my cell reception is questionable at best sometimes. I live in Maryland, and it's now a law that we can't use cell phones at all while we're driving unless we use it handsfree.
I've tried a slew of combinations including Speedmod and Firebird2 with at least 4 different modems including JK3, JK4, JL2, and JL3.
So here's my question to you all:
With your custom kernel/modem selection, do you have usable bluetooth WITH good cell reception? And if you happen to have a FORD vehicle with SYNC in it, does your setup work clearly with it? (Even though I'd imagine it to be the same with Honda/Acura/Nissan/etc...)
Please include your setup in your post!
Long island ny, in know that is not your area, but speed mod, dill pickle, firebird, ursa minor, sucker punch, paragon kernels with jk3, jk4, jl2, npk1 modems all work with my ford sync fine.
Current set up is
Paragon rom
Dill pickle kernel
Jk4 modem
In PA running Serendipity 5.10, Suckerpunch #50 and JK4. Sync also works great in my car and cell reception is also good.
I have a Sprint tab. I wan't to upgrade to gingerbread, and I don't care about CDMA service, but I have to have wifi. GPS would be preferred but I can live without it. It would also be nice if it wasn't a brick afterwards.
What are my options? Can I just flash Overcome without a modem file? Is there some sort of null modem file I can flash? Is there a different ROM or kernel I should use?

Also very interested in this.
I recently put quite a bit of effort into getting GB to run on my Sprint tab. I use WIFI only so I was not concerned with a working CDMA radio. I attempted to flash the European GSM firmware to my device. I tried flashing the kernel and system only, leaving the CDMA radio file intact. I also tried flashing several GSM radio files to the device. In the end I was unsuccessful, and it took several hours to recover the device to an operational state.
If you WERE to get GSM GB working, there is a good chance that GPS and BT wouldn't function. That's kind of a deal breaker for me.
tldr; Sprint users are screwed until the official release of GB because the Overcome team doesn't care about us and the only guy who seems to know how to work the CDMA is making a crappy honeycomb build instead.
IMHO other devs should make a version of the ROM with all data taken out because it'll work for Sprint users and GSM users who tether instead of paying out the rear for a data plan on their tab.
----------------------------
tonman23: Thanks, but i was looking for gingerbread, not honeycomb. It's great that spacemoose can prove it in concept, but I don't like the honeycomb interface, and I'm not interested in flashing a half broken version of it to my phone. I want a stable gingerbread build for the improved performance and minor UI features.
etvaugha: BT & GPS are handled by chips completely independent of the modem. I can't post a link because I'm still new here but the ifixit galaxy tab teardown shows clearly that GSM tabs have distinct BT/WLAN & GPS chips. That's pretty standard fair for android devices, so I doubt they changed it simply for the CDMA models.
It also clearly shows that the modem is a GSM only chip, so the bin files are completely incompatible. The only solution is ROMs that will boot even if the modem isn't working right.
----------------------------
According the the Overcome 2.0 FAQ, the problem is that the phone won't finish booting if a valid modem.bin is not installed. Apparently the phone waits indefinitely (one user, PFOI, mentioned something about it working after 30 min or so) or crashes during the boot because it doesn't get a proper response from the modem chip.
This could easily be overcome if the devs would compile a WIFI only version of the rom/kernel, that doesn't require or support either modem (CDMA nor GSM). It seems to me that the this would be good for both sides, as the data plans for tabs are a rip off and smart users are going to tether their tabs in a mobile situation anyway. It would also probably be better for battery life considering there'd be one less chip running and less bus activity.
I'd imagine all that would be required is removing the modem initialization during the boot sequence. There might be a need to replace the functions that query the modem's status with static value return statements, but when the tab first boots it reports no service, so it's got an inherent ability to deal with not having network access. All that's needed is a couple little snippets to tell the device it doesn't, and to keep it from trying to get it.
Hello All,
Have just started using this forum and failed to introduce myself previously, my name is Jay; I am 27 from DC but in Afghanistan for a few more months (yea..sucks) new to rooting, flashing and all that but I have recent interest in it and it passes the time better than most thing we are "allowed" to do over here.
I just switched from a HTC Desire to a Galaxy Captivate
So far...I have unlocked it (via cellunlocker.net), upgraded to the leaked 2.3.4 Gingerbread, Rooted using the 10step method posted here, Installed Victory v1.5 Rom, tried flashing Talon kernel but bricked the phone and had to redo the above...
My question is to those more knowledgeable than myself with all this...what is the best Kernel, Rom, Modem...whatever else...that I can have on this device to keep it running smoothly, fast and reliable?
I do all the basic call, txt, surf...play games, watch movies, use apps, etc...not a developer but want my phone to be tweaked as much as possible so it does not seem outdated or lag with new things being added.
My current settings are:
Baseband I897UCKH3
Firmware 2.3.4
Kernel 2.6.35.7-I897UCKH3-CL461307
Build VictoryRom_v1.5
There is nothing wrong with the phone...as I said above, if I could do more to it and have an overall better device and pass some time here I would enjoy that. Victory seems great but all I notice myself is the battery indicator has changed and...thats about it (a lot likely goes unnoticed by me)
I do have one problem with the phone that maybe a different modem can fix? (I hope) for some reason my GPRS will not work out here with my browser...I can use the market and apps that connect to the internet but my browser seems to be WiFi only. I have changed the settings from usa to europe since I am using a sim from over here but no luck...and added the gprs settings to the phone which allowed apps internet access but zero for browser..any ideas?
I really thank anyone who takes the time to reply...I am sure teaching a new person in this is annoying just as showing the new guy here how to clean his weapon...lol...but we were all new at everything once and I thank you all for reading my novel
-Jay
Jay,
Thank you so much for your service and contribution to our freedom, I know it must be hard to be away from the life you once knew. Hang in there It's not for nothing. Hopefully someone will be able to help with your GPRS settings. I am running the same setup on my captivate only I have used Boogs kernel to install clockwork recovery as well. You can flash boogs kernel over the kernel you have now and that will let you flash roms or speedmods later. If I were you I'd keep my eyes peeled for GPRS settings in your area and wait for EXT or speedmod kernel for the 2.3.4 They are saying RFS is pretty quick to begin with though. It may be hard to beat but im sure one of these great Devs will figure out a way to make 2.3.4 smokin fast. Once again thanks for doing what you do. Keep your head down Soldier!

If you like using your mobile providers Net, you might give I9000 ports a try. They allow for better Upload speeds but you will sacrifice Audience chip support (noise suppression processor that only I897 have). Also since I9000 source usually drop first they have all sorts of kernel mods like Voodoo sound, Voodoo color fix, BLN, init.d files tweaks like V6, among many more. Sadly I897 native roms always play catch up with I9000's.
Personally I prefer native rom, because they tend to run smoother for longer periods of time (I9000 tend to slow down over time on my phone, but thats just my experience) and I don't use ATT's network a whole lot (90% of the time I'm around a wifi connection) and I like the audience chip, it is a phone before anything else.
Edit: Also there isn't a "best" rom, kernel or modem. Each rom has their own pros and cons, same as Kernels. And no 2 phones are the exact same so not all of them take well to all the tweaks, mods, etc. And most of the time i9000 kernels wont work with i897 roms, at least in GB.
