[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] Help me find the right radio...please

OK, I'm running Cognition 3.04 with the Speedmod Kernal.
People are telling me they can't understand me on the phone. For what I've learned through flashing over the past few months and reading around, I believe I need a different radio. Am I wrong? If not, can someone point me in the right direction?
I've seena few references to radios on here, but never with a link or a better explanation as to what details I need to look out for.
Thanks for any help.

OK, so should I be looking for modems then? 'Cause I went through that thread and flashed both UCJJ4 and UCJI6 (one at a time of course) but neither fixed the issue.

the problem is not your rom, but your modem, i believe. try jl2, jk4 if you are on i9000 rom.

Hmm...Cognition is made specifically for Captivate...was it wrong to assume is was a i867 ROM?
Is there an easy way to tell on the phone which model my ROM is built for? The "Baseband Version" reads I897UCJI6. Is that a hint?
Thanks for your help guys.

Your problem is you're using an i9000 kernel with a captivate modem. Cog is considered a pure captivate rom, so if you installed speedmod (which is based on an i9000 kernel) you need an i9000 modem. I think JK4 seems to be the most popular

This is so frustrating...I'm trying to not be a newb and figure this stuff out, but things that say they're for i897 aren't...ugh.
Well, I flashed JK4 and it works. So I guess the speedmod for Captivate isn't actually for Captivate.

Things that are for the captivate are for the captivate and the version of the speedmod kernel you flashed from the captivate forum is for the captivate, but...
What everyone is talking about above is what those things were ORIGINALLY designed and built for. In short most things out there were originally built for the i9000 (since AT&T is dragging their feet on releases) and then ported over to the captivate, meaning the code, config, etc. is changed a bit to work with the captivate. So what everyone is saying above is that speedmod started as an i9000 kernel and works best with an i9000 based modem.

[Q]Hspa on stock froyo rom....?

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?

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

[Q] Any Kernel work on back camera

I have been using I9000 rom with speedmod kernel and 850 modem for i897 device for a long time.
I installed different kind of i9000's Captivate kernel. None of the i9000 kernel's Captivate work on Tango and Fring video chat. I always get black screen on Tango video chat and Fring always crash when video turn on.
I tested on i9000 rom with Cognition 4.3's kernel and I897UCKB1 modem. The video chat work, but this I897UCKB1 modem is horrible download and upload speed while using video chat. That's why I didn't like to use I897UCKB1 rom because the 3G speed limited by AT&T. If I use any i9000's modem with Cognition 4.3's kernel, the voice call will not work.
I think i9000 kernel for Captivate must disable or remove front face camera function in order to work on Tango or Fring video calling.
Anyone know how to fix this?

Captivates have no front facing camera.

That's why need to disable front face camera on the i9000 kernel's Captivate.
And Cognition 4.3's kernel able to use video calling, but not on any i9000 kernel's Captivate.

They gave a proximity sensor and a light censor on the front that is often mistaken for a camera. As for moderns and kernels, I would recommend reading the modem thread. It will put you on the right path.

I'm pretty sure the op knows there isn't a forward facing camera, what he is saying is that the video chat works on kb1 but not on i9000, like the i9000 kernel makes the app look for a forward facing camera and then it doesn't find it and crashes or shows a black screen due to no camera. He wants the kernel to have the app go to the rear camera like it should. Right?

I knew Captivate never have front face camera since I have this phone.
The only problem i9000 kernel still contain front face camera code.
The Cognition 4.3's kernel seen like wasn't or because it is base on Captivate rom.
Either modify or disable front face camera code inside i9000 kernel or use Cognition 4.3's kernel with hsupa enable modem.

My apologies. I misunderstood.
Have you tried using the kb1 roms (cognition, fusion, torch ) with existz kb1 kernel? As far as modems, there are only 3 I think for kb1 roms (KB1,JJ4 AND JI6). If the modem doesn't match rom and kernel, weird things happen (no bluetooth, no call volume, static). I hope this helps a little, eden if it doesn't solve your problem.

All are Captivate modem (KB1, JJ4, and JI6) worked with KB1 rom except I don't have HSUPA speed which is I don't want to use AT&T modem.
i9000 rom + i9000 kernel for Captivate + i9000 modem: need to fix kernel only use back camera
i9000 rom + Captivate kernel + Captivate modem: everything work except no hsupa speed

im not sure if you will get what you want. it would require a lot of knowledge of the sources and mixing captivate and i9000 sources from a 2.2 kernel and a 2.2.1 kernel. not that it is nessessaily hard, it might be easy for an experienced dev. the devs dont really know till they try but im not sure they will mess around with it. most of the significant kernel work is being done on irc chat and in the i9000 forum, most of it is not i897 centric but latter ported to i897. it may tak a while to get something like this done and after the source for 2.3.3 is realeased im not sure that it will ever get done. problem is that noone requests it. i understand the need for hsupa in combination with video chat. without a 2 way connection hsupa is almost useless. many broadband isp's dont provide an equivilent to hsupa upload speeds. well right now atleast you need to choose between slow choppy video calls on hsdpa or no video calls at all on hspa making hspa fairly useless. what a conundrum
have you tried using a pure i9000 rom and not a captivate port? like strait out of the i9000 forum with a reorient kernel? because they may have something in the settings apk to swap the active camera for that.i dont know for sure though.
edit, forgot but you can triy the ursa minor kernel. it is the i9010 kernel but it is 2.2. there is also the i9088 2.2.1 kernels from kp2 and kp5 but it is hard to find and you might have to settle for a stock kernel in that case.

well try the andromeda rom or the ursa minor kernel from andromeda thread.
i really suggest trying andromeda if you are gonna use a 2.2 kernel. not much sense in 2.2.1 without the kernel. andromeda has some fantastic battery life for most users and alot more, i suggest changing the modem though jk4 doesn't work well for me or many other captivate users. calls suck. kp1 and kc1 are two that i can verify work well.
there may also be a kp5 dump around here somewhere with the kernel but you wont have voodoo anything. still you get a 2.2.1 kernel for the captivate with hsupa
edit: http://forum.xda-developers.com/attachment.php?attachmentid=531565&d=1299080836
this should contain a kp5 kernel with voodoo injected in. it was the origonal kernel used in dragon. dont think it has voodoo sound just lagfix
edit edit: http://forum.xda-developers.com/attachment.php?attachmentid=558036&d=1301688592 this is the ursa minor kernel for andromeda built from i9010
sources. as far as 2.2 kernels for captivate go this is the one to have! 2.2.1 may benchmark a bit better but this is a seriously fast kernel with hsupa support. use kc1 modem you will be happy.
Edit 3: I use glitterballs' kernel v.5. It is a pain in the arse but it is jpx/y 2.2.1 like the other i9000 kernels and is working for me on fring with dragon rom. I just downloaded fringe and did a test call. I can see the image from my rear camera in the lower corner. Glitterbslls really knows what he is doing. He needs to come back to the board. If you use this kernel disable all lagfix first and convert to ext4 after to include the /system partition. Also flash with neldars app. You will have problems flashing in recovery because of steam. You can also extract the zimage and .tar it for odin flashing.

we spent a long time on that rom. it started its inception in December and made its debut on XDA in January.....you will be hard pressed to find any REAL issues

if there is a rom to flash and use long term andromeda is it. i had andromeda 1.something for almost 2 months i didn't change the kernel or overclock it and i didn't even have the stock rom for that long. but switched because i was curious about the roms from the i9088. would go back but dragon keeps getting better and i want to see what dagr8 produces for the final release, he was a dev on andromeda. i think the whole andromeda team komin dev group does top notch work.

[Q] During call other party hearing loud ticking noises when using a custom rom

Hi guys,
Rogers Captivate, i896.
While using my headset on the following custom ROMs I am finding that the other party can hear these VERY VERY loud ticking noises. However if I unlock the screen during the call (while using my headphones, the noise will not occur)... of course locking the phone during the call while using the headset will cause this noise to appear at short intervals. There is no noise at all without using a headset.
This problem however does not occur while on the rogers stock 2.2 ROM. The headset does not cause any sounds on the iPhone either.
Any ideas as to what is causing the noise so that I can start using custom ROMs again? I cant live without my firefly....
Thanks in advance.

had similar issues with 2.2 roms. what roms modem kernel are you using?
should be good with speedmod and kc1 modem or kp1 modem.

I got the ticking noises with Pheonix (the release before ultimate) and Ultimate, Serendipity 6.2-6.3, Firefly 2.6-2.9

what kernel/s do those use. also change the modem.bin to one of the newwer ones. it is a i9000 modem on captivate issue. jk3 and jk4 really are not captivate friendly. kp1 is. kc1 is also doing well despite being an i9000 modem.
some are even using the gingerbread modems if yo want to try one.

After a quick run through i am noticing that most run speedmod k12 / k13.
Hmm so you are thinking its a modem issue?
I suppose ill try flashing alternate modems this time. I guess i have some reading to do
Perhaps i might even try out some other roms that have alternate default modems.

speedmod shouldnt be a problem but if you are not interested in overclocking you can try maybe ursa minor. it is the andromeda kernel and 2.2 rather than 2.2.1 but it is no oredinary 2.2 kernel. it might not benchmark in quadrant and linpack as well as speedmod but feels quite speedy. it uses kernel modules that can turn on and off to minimize overhead as i understand it.
