[Q] 850mhz 2.3 modems?

Do any of the 2.3 based modems support 850mhz for 3g?
I've tried JVH and JVO, but neither seem grab an 850mhz signal. I've gone into secret codes and added 850 to the combi bands, but the phone never grabs 850.
This leaves me sitting on edge while at home, with weak signal. On 2.2 based roms I have no problem with the various modems that support 850mhz for 3g.
This is on a Bell i9000m.

Flash JL2, set 850 as the only one, then flash JPD then you'll be able to flash anyone you'd want.

those will work ok on a gingerbread based rom? They were released with froyo roms, just want to make sure I am not going to kill anything.

The modem files are firmware agnostic....they can be used with either froyo or gingerbread.

Thanks guys.
Did as directed:
Flashed JL2, set it to 850 only, rebooted, flashed jpd, rebooted, flashed jq1, set it back to auto and added 850 to combi.
Seems to be working!

Questions about Bootloaders, Kernels and Modems

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

I9000 Bootloader

i have captivate with at&t bootloader,if i flash a custom rom which is built in i9000 bootloader is it make any difference ?. after flashing i9000 bootloader can i use galaxy s custom rom on my captivate?.

Custom roms don't usually have bootloaders built in. That us something that"stock" roms do. ROM developers usually remove them, providing a link in the op of their thread for those that need them.

The i897 and i9000 gingerbread boot loaders should work for any non-CM7 based ROM in the development section. The only issue you may have with an unmatched boot loader to the ROM is the stock music player skipping when the phone is locked.

From my understanding att gb roms doesn't work on i9000 gb bl. Can someone confirm this? Also cm7 roms works on GB bootladers (both att and i9000) for most people.

i897 GB bootloaders and I9000 should work each way. As mentioned before the music player issue is there. That being said Some devs feel that if you are running I897 BL on a I9000 port and its acting funky could because of the BL. Same applies if you are on a I897 rom with i9000 bl's. As to my knowledge CM7 and MIUI work on both eclair bl or GB bl, I do believe there might be kernels for specific bl? Not sure anymore, stopped following a while back.

Don't know about cm7, but i9000 loaders on MIUI can cause a few minor acts of weirdness, the biggest being not able to see your external sd card. Also, in my experience you haves to be on a Samsung based ROM because if the file system to change bootloaders. I've tried ato c change while still on MIUI and I got nothing but boot loops. As for kernels, bothGlitch and Platypus kernels will work on the I897 GB bootloaders now.

[Q] Gingerbread modem

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.

[Q] Miui Rom for Canada

I would like to know which GT-i9000 MIUI Rom is being used for Bell in Canada?
Also which modem file?
Thanks

I've not tried any of the MIUI roms.
My experience is with various other roms, both ICS and JB.
I've always had to flash a modem over the stock that comes with the custom roms.
The modem I use is from cm7 and it's a KG3.
The specific modem zip file I found on xda thread [CM7/MIUI/ICS/CM9][06.01.12] Modems + Bootloaders(MD5) is:
radio-cm-7-GalaxyS-KG3-signed.zip
ps. I'm currently on the Bell network.

Your i9000 is working on the Bell network.
You are using the KG3 modem.
Would you please tell me the version of ICS or JB you are using?
Also did You install the first version and then update to your current rom version, or can I just install the latest version?
Thank You
