K so i have an i896 captivate and im on rogers, running Serendipity 4.0.1 rom.
I read somewhere that you can flash different modems, and that flashing the stock modem will help with signal and gps.
Soooooo does anyone know to flash a modem, or where i get the stock i896 modem, or what modem provides best signal gps and battery life.
Also what are the general rules of thumb for flasing modems on differnet roms..
Thanks

So far have only found instructions at to flash a 'package' of firmwares and of course dropping in a new kernel using odin but as yet havn't found out if a modem firmware can be flashed without changing the pda.
Is this possible and if so then maybe for, say closely related roms such as the various permutations of the original froyo?
If its possible then still the pda rom that remains act as if nothing is amiss the same as flashing a kernel?
And finally!
Currenly on jpy (voodoo stock)/jpy/jpy coming from unbranded froyo from my local area. Since changing I have a hunch the modem is not quite optimized for our networks and want to try the old jp5 modem with jpy pda.
Final note... Jpy seems exactly like jpo plus voodoo 5 to me except for the minor changes to ui except that battery life is TERRIBLE! When I use apps or data but the same on standbye... Hence I feel the jpy modem is not optimized.

I would like to do the same thing. Use a JP5 modem on a JPY rom (in my case Insanity Rom).
Where did you find the JP5 modem file? I tried a search on this forum and the best I could do was this but I can't find it on there.
I have flashed succefully a diferent version of modem on JPU earlier this month and worked well.I flashed JPU with pit and CSC file+repartition clicked,the i choose a JPA modem and flashed it seperatelly ,NO pit NO repartition.All went good.I guess its just a matter of versions,probably cant flash a modem of 2.1 versions,but a 2.2 would probably work.
Hello folks;
A quick question...
I have the latest SpeedMod, and in a lot of threads in the forum people recommend flashing an i-9000 modem with the kernel, with the concern of compatibility issues where you would have the i-9000 kernel with an 896/897 modem.
I haven't had any problems with the stock Rogers Froyo modem(uxlj1) and SpeedMod. Should I flash a new modem anyway? What will the benefit be? Am I just not noticing real problems that are there, or is there something to the Rogers Froyo Modem that works with SpeedMod without the need to flash a compatible modem?
Also, what could go wrong if I do? Seems some people have trouble with data and bluetooth after flashing a new modem.
If you have working bluetooth I believe there would be no need to flash another modem
Thanks for that.
Whenever I flashed Speedmod without changing over to an I9000 modem with it, I had horrible voice call issues where it would sound like I had my vocal cords removed and talked through one of those voice boxes.
Just about to flash Darky's ROM 9.3. Planning on flashing the i897 500 mhz speedmod kernel afterwards, plus of course an i897 compatible modem to match the kernel.
First, is it necessary to do a full wipe if I'm currently on a stock rooted i897 with eclair (2.1)? And must I really pull the sim, sd, and battery? If so , why?
Second, should I flash Darky's captivate fix before the rom or not?
I get conflicting reports when I search the forums.
Finally, what modem(s) would you suggest? I'm in PA (Harrisburg area) on ATT so I need the 850 Band. Suggestions? I'm assuming based on my research here I'll need an i897 modem to match the i897 version of the kernel (assuming it's really necessary to flash the i897 Speedmod instead of using the one Darky's comes with(???))
P.S. Safe to do all this with CW from recovery menu? or must I really install/use Odin? (more work, sigh)
Thanks in advance.
First, is it necessary to do a full wipe if I'm currently on a stock rooted i897 with eclair (2.1)? -Yep, it's not hard. I have 2 bugs than I not to do it. Not work Home button, and my cappy play music throw the speaker than I plug earthphone and the opposite .
And must I really pull the sim, sd, and battery? If so , why? - No. I Flash 5 times and nothing bad happens. And my phone plug into the PC via USB than I flash.
Second, should I flash Darky's captivate fix before the rom or not?
I get conflicting reports when I search the forums. - I don't know. I do not apply any fix, all works perfect.
Finally, what modem(s) would you suggest? I'm in PA (Harrisburg area) on ATT so I need the 850 Band. Suggestions? I'm assuming based on my research here I'll need an i897 modem to match the i897 version of the kernel (assuming it's really necessary to flash the i897 Speedmod instead of using the one Darky's comes with(???)) -Dont now I'm from Russia.
P.S. Safe to do all this with CW from recovery menu? or must I really install/use Odin? (more work, sigh) - I instal from Odin because before I flash CM7 (on CM7 very bad video works) Use Odin very good program. Not difficult. But if power off yve got a problem.
I have been running firefly and apex. Each of them, when I flashed UCKB1 , I get reboots over and over. I just flashed the Continuum rom. Do all the modems have to start with update? Because UCKB1 says CMWmodem.UCKB1.zip. I'm just not sure what cuases the reboots, but they do come when I flash a modem.

You need to match the modem with the kernel - if you're using an I9000 kernel (like Onix in Continuum), you need to use an I9000 modem. UCKB1 is an I897 modem, not an I9000 modem.
If you try to mix them, various bad things can happen.
EDIT: No, the modem filenames don't have to start with anything specific - they can be named pretty much anything.
Thx for the reply. I guess I'm getting in trouble by using SGS tools thinking that all the modems are compatible. So anything with a I9000 in the zip?

Probably, but like I said - the filename can be named anything.
Here's a good list of modems, broken down into I9000/I897 and 2010/2011:

(The year part doesn't really matter for compatibility - it's so you can see when it came out)
I've been running XXJVK for the past few days to test it out (on Continuum 4 + Onix 2.0.3), but among the others, ZSJPG seemed to give me the best performance.
Jk4 is a good starting modem. It.s an I9000 modem and is compatible with most all roms/kernals. Get stable then start reading the forum posted above. It will make more sense. It works well with firefly.

How do you back up the modem? I'm currently running the kf1 gb release, and I was wondering if there is a way to back up the modem. Voice quality is important to me, and the stock modem works great for my I897, unlike the I9000 based modems. I'm concerned that when the incredible devs start pumping out custom roms for this release they will use a different modem in order to enable HSUPA. Voice quality is more important for me than the mimimal difference I evperience between 3g and H. Any options?
there isnt a way to back up the modem. you can snag any modem.bin file out of any rom zip and use the regular ODIN. the phone section will accept modem.bin file, or you can use Heimdall ..... either way there is no backup, you just flash a new modem...or you can do it from CWM using a modem from the MODEM THREAD
