[Q] Darky's rom v 7.7 reception issue

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

[Q] Ginger Clone 2.2 Final R5 best kernel and modem combo

what would be the best kernal and modem combo for this rom i really want good battery life I just got my captivate 6 days ago and out of 3 roms i like this one just want to know the best choices.

Speedmod k12t kernel and KP1 modem.
Take a look at my signature, results speak!!

Nothing against what any particular person will state or tell you to use, not all combination's will necessarily have the same effect from phone to phone. This is really the same as which ROM is the best because what works well on phone "A" might not work the same as phone "B". Just try different combos to find what your phone likes because these phones are very finicky.

i've been reading and this is what i come up with looking at the rom i flashed this is what is says.
model #sgh-i897
firmware 2.2
baseband i9000ugjk3
kernal version 2.6.32.9
build # gingerr5
off this info which kernal would i flash the one for captvate or the one for galaxy s i9000.i just dont want to do something stupid sorry for the questions.

You would flash an sgh-i897 kernel.
Here's a link to hardcore's kernel, http://forum.xda-developers.com/showthread.php?t=893880.
you can use sgs kernel flasher to install it.
The link is at the bottom of the original post in the attached files box

not to ask more ? but is that because my phone is still based on captivate but with just a base rom.and what is really a base rom 2.2 mod to work on captivate?

Yes, the captivate sgh-i897 doesn't have 2.2 froyo yet, because it hasn't been released yet, but developers used the leaked version of froyo to base their roms off of. An i9000 rom is actually a rom from an i9000 galaxy s phone that was adapted for the captivate. But basically, all you have to worry about is whether or not the numbers match up.

Modems, Base rom, and kernels

From my understanding... a i9000 base rom should be used with an i9000 modem and kernel. At the same time a captivate base rom should be used with a captivate based modem. Please correct me if this is not true.
Now, what I don't understand is why are there roms that mix it up? Firefly uses the rogers Froyo.. which is JL1 captivate base rom, but at the same time use a JK4 modem which is i9000 from bell.
I'm not exactly sure where JPY, JS3 and more recently JS5 came from either.

generally using a an att or rogers rom will be incompatable with another modem. not that the phone wont work but you lose bluetooth audio. it is posible that this doesn't apply to the official rogers froyo or that they have accepted this as a minor compromise for adding hsupa.
i dont know of another reason to match modem to anything, many say to match it to the kernel but in the case of an att rom that doesn't help any, and i have run t959d modems on i9000 kernels and roms and there are no ill effects. so that theory is out.
some even like to run captivate modems on other roms giving up hsupa because they get more stable results.
really the non rogers/att modem on a rogers/att rom is the only known problem. all other "rules" are mearly safe suggestions, but if we did things the safe way all the time we wouldn't learn anything.
the only other criteria to choose a modem is that on att or in canada you want to use a modem that defaults to the 850 band. basically if you want hsupa use a bell or telus modem on i9000 kernel and non att/rogers rom. there are also chinese and austrailian and newzeland and other modems that work just fine. i find the kp1 from china to be the most versitile. i think the modem has all the bands so it's better for international use and i get the most satalites with it though the positioning is less stable untill you tweak the gps settings a little.

@ dani897 are you meaning the kp1 has all 5 wcdma bands enabled? i know of 850/900/1700/1900/2100 that would be handy.... is there any known draw backs or just try and see? it would be nice to change countries/carriers without finding/ flashing a new modem. great info thanks.

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

I9000M Questions

I have a Bell (Unlocked running on Telus) I9000M SGS and I have tried many different ROMs to try to get the GPS to work, but there is always something about the ROM that makes me change.
I have tried ICS as well, but that didn't work at all. I have tried ROMs from Europe (JVR and JVS) and while the GPS did work, the phone didn't have the reception it should have had. I am now back on stock GB 2.3.3 - UGKG3.
Has anyone ever solved the GPS problem with the Bell ROMs? Has anyone used any other ROM that worked as well as the stock ROM, but with working GPS? For those with an I9000M, what is the best ROM/kernel you have used.
Another thing, I have had the M/B replaced due to the dreaded internal memory problem and with the non-existent GPS and the lack of Android updates to Canada, will you get another Samsung phone? I would love the Note, but can I trust Samsung?
Thanks for the info,
Ian

I have a i9000m through lleb and I have been using this modem i9000 ugjl2 and my gps is perfect.
And if your using google map I also find if you change yout scripts from N-America to europe you'll also get a faster gps find.
