Zcka6 Trial

I went ahead and flashed the test only Zcka6 modem. Im currently waiting for it to connect to the AT&T network, it is taking unusually long. Im going to wait about 15 minutes, before reverting, if it doesnt connect, ill let you guys know tho.

update

No Go, It wouldnt connect... Cant really fiddle with it right now, ill try flashing with odin instead tonight, and see if that does anything.

[Captivate Android Development] devz3r0:
I believe it is, after looking it up. Strangely, it's in the I9000 section on samfirmware, and listed as 2.2.1. I thought the Nexus S came with 2.3 pre-installed no?

for sgh-i896, running darky 9.0.2 on speedmod kernel k12Q 500Hz i'm currently using the TLJL3 modem and its working fine... I've had no problems. But my question is: is the UGJK4 modem better? And if so can i just flash the zip file using CWM recovery. I also have the lagfixes and all tweaks enabled.
[Captivate Android Development] mattsternc:
Signal strength and bars not displaying correctly??

So I've run into something a little odd. I've tried both kp1 (ate my battery while in airplane mode overnight) and jl3 (currently running this). Both of these will only display a max of 4 bars, even in places where I should be getting 5 bars. I have a microcell and even standing right next to that, I am only getting 4 bars (5 before I changed modems, with the same db readings).

Any ideas? It's not that big of a deal really, but I found it rather curious ..... :confused:
[Captivate Android Development] Dino.:
Question, the modems also effect wifi correct?

because with ZNKP1, the wifi fails to enable. as it starts connecting, it just stops and says error. Not sure what it is, but it does bug me >.< (only fix is a restart)

Also i had only one person complain about call quality and low volume.

I guess I will switch to JL2 for now.

just for the sake of battery argument.

P10.2, Fireball 2.03, KP1

Angry birds for 30+min, like 30+sms, bln

22h 53m 8s with 31% left

1h 32m 49s 62% Display

1h 14m 9s 26% Calls

22h 53m 8s 8% Standby

21h 20m 18s 4% Idle

I think that the battery life is good with KP1. But ill see what i get with JL2.

I am using UGKC1 on my captivate running continuum version 4. I am using onix 2.0.5 kernel. I have also flashed crysis theme and HC puzzle unlock and a UOT. Zip (window animations) . Which modem is better UGKC1 or xxJVK? I see that JVK is a gingerbread one but I see lot of ppl using continuum (which is a 2.2.1 froyo based ROM). Please someone advise me on this. I am always on the lookout to improve performance of my captivate phone. Thanks a lot!

[Captivate Android Development] mrhaley30705:
Jvk is good. I'm running jq1 on a paragon kernel. To determine which is best for you, try several to see which suits you. See Shomans instructions (in his sig) for flashing certain modems.
[Captivate Android Development] antonyvijai:
Thank you! Since I already have UGKC1, can I simply flash JVK through CWM on top of it?

[Captivate Android Development] :
JQ1 has been awesome for me, but Ive been hearing a lot about JVK and now that the GB source is out and JVK shipped with it, Im wondering how is JVK compared to JQ1?

I know its all region specific, but has anybody in California used both? What does everyone else think when comparing the two modems together?
[Captivate Android Development] WickedNite:
I tried both and JVK suits best in where I'm at. JVK's gps locks faster than JQ1, sometimes JQ1 doesn't lock at all for me, I don't know why. DL speeds are better too.
[Captivate Android Development] :
I used Shoman's meathod to get JQ1 working on 850... and it seems I can just go straight to JVK from JQ1... but can I go back to JQ1 or do I have to do the happy dance all over again?
[Captivate Android Development] shoman94:
Should just be a straight shot.... It was for me. If it doesn't work, you'll have to do it all over.
[Captivate Android Development] :
Thanks to both of you for fast answers. Ill try it out right now...
[Captivate Android Development] markmunsch:
Well after a week or so of trying kc1 and jv9 I'm abandoning both to try jvk 1 more time, and will probably end up back on jq1. Both kc1 and jv9 were good by I've had weird battery drain since I flashed them, can hardly get 8 hours of use with them. Narrowed my issue down to either kernel or modem and I've switched kernels and still the same, so it can only be the modem. Has anyone else has battery drain issues? Lately I've had alot of 50% without signal issues.
[Captivate Android Development] jpcdeux:
UCKB1? Any good? This is all new to me...
[Captivate Android Development] sicmadek:
i never had drain problems but in the end jvk turned out to be the best for me. i got the best battery life ever yesterday. precision 4.0 speedmod k13e and jvk.
[Captivate Android Development] {Angel}:
I have posted about this before. I suspect that almost always this will be due to circumstance. When I have experienced this I will check battery history and find that my phone has not been sleeping and a reboot will fix it for me. I have not had this again in a while since I did a few changes to some stock apps in my phone but not sure if anything actually did anything our its just coincidence and it will pop up again.

Also there are many reports and I can confirm this has happened to me is that upon boot the battery usage shows 50% time without signal, not sure if its drains power as I quickly toggle airplane mode to fix it. This is a known bug that affects many phones not just the galaxy s.

So check your history before knocking any kernel our modem you have just flashed.
[Captivate Android Development] markmunsch:
I ran each modem for at least 3 days, with kc1 even longer. On both I had the 50% without signal multiple times, while that was non-existant on other modems. No one else may ever have the issues I did, these phones are so un-uniform that this could be an isolated incident of just me. The data speeds and call quality were great on each one, just battery life sucked for me on both kc1 and jp9. I could go about 24 hours on standby if I didn't use the phone, but as soon as I did anything with it was lucky to squeeze 8 hours from it.
[Captivate Android Development] jpcdeux:
Installed JL2 and couldn't make phone calls. They would start, go for roughly 10 seconds then hang up. Couldn't hear ringing or anything. I'll stick with KB1, I know it works...
[Captivate Android Development] {Angel}:
Which one is jv9? Do you mean jp9? In that there are 2 different jp9s.

I can assure you the 50% time without signal is not modem related, its not even samsung related, appears to be an android problem. Do a google search if you dont believe me. Toggling airplan mode off and on fixes it. Somebody even made a small app that did this after each boot. Th reason you have not seen it before may be because you never noticed it before or you dont reboot very often. Also check bat history and see if your phone is not sleeping when you notice a massive drain. I suspect this can be due to an app that can autoboot and stop phone from sleeping.
[Captivate Android Development] {Angel}:
Where you running jl2 on a captivate kernel? If so you will have problems. You need an i9000 kernel to run jl2.
[Captivate Android Development] Madtowndave:
Refer to page 1 of this thread, original post...

If you currently running kb1, then you are clearly running an i897 Captivate kernal...so you are either stock at$t froyo, or if custom, likely on Cognition 4.x.

You MUST match kernal and modem. Almost all of the modems discussed in this thread are compatible with i9000 kernals, which is what 90% of custom ROMs

are based on.

[Captivate Android Development] markmunsch:
Yeah angel the 50% bug may not be a "modem" issue as I do see it's an Android thing, but it only showed up after flashing KC1 so it seems odd that it didn't stem from this, as that was the only thing that had changed on my phone when it appeared, no new apps, kernel changes, themes, etc. Anyways, not going to hijack the thread anymore, so I'm back to hunting for a modem that works well with good battery life.
[Captivate Android Development] jpcdeux:
I'm sure I did something wrong. This is all new and nothing is clear cut and dry

[Captivate Android Development] {Angel}:
Nothing needs to be changed for the 50% bug. It seems to happen randomly. Not a modem problem. Its just coincidence.

If you have not tried already. Ubjp9 gives me excellent excellent results. Vvjpg is one worth trying. Good luck.
[Captivate Android Development] :
Back to jq1 for me. Jvk was horrible on battery and didnt hold onto 850 as well as jq1. Oh well, now I know what works best for me.
[Captivate Android Development] sicmadek:
interesting...jvk has awesome 850 signal and super battery life for me.
[Captivate Android Development] WickedNite:
Weird for me is my phone doesn't go to 850 unless I force to, even with other Modems. That's for everywhere I go. Lol.

[Captivate Android Development] grkmaster:
Same here . I was running alright with JK4 and decided let me try JVK since I been getting decent battery life and how it compares. I went out and my battery even on idle was just dieing. I switched to JQ1 and havent had an issue yet, other than my job which I always do.

Ive also realized when I force 850 I have strong signal around -69 or so (mostly my house I realize it) and every time I put it on automatic it switches to 1900 and its still strong signal but around -80 or so. Ive noticed that most modems do this to me.

Hey,

Did anybody try I9010XXJK9 (Armani Modem)?
[Captivate Android Development] alexige:
I saw this same type of thing in the Xperia X10 forum. Since that is a 3G phone the settings are more in tune with the Captivate. It depends on the provider what the exact specs are but for AT&T they are:

ro.ril.hep=1

ro.ril.hsxpa=2

ro.ril.enable.dtm=0

ro.ril.gprsclass=10

ro.ril.hsdpa.category=8

ro.ril.enable.a53=0

ro.ril.hsupa.category=5

When I tried this in South Orange County, Ca on a number of I9000 modems the benefit was negligible. I tried it for a good month but took it out in the last few weeks. This just gets pasted in the build.prop file in the system folder.

[Captivate Android Development] RandomZero:
So I've been having problems with my modem (or so believe) for the past couple of weeks.

About two weeks ago, I was unable to send txt msgs to one person and then an hour or two later I lost connectivity completely. After troubleshooting with my SP (Rogers) for a while and after pretty much getting no where, the issue resolved itself after I had done a master restore.

But now, the problem is back. They've decided to issue me a swap, but I want to find out what's really going on.

I have an older phone (Sony Ericsson K790) that works fine, aside from the SMS problem.

I'm using firefly 2.9 with Speedmod k13E and the default modem (JK4 I believe).

Anyone have any ideas of what I could do? I'm thinking of switching to the xxjpy modem and seeing if that'll help.
[Captivate Android Development] mbc663:
why not just try them all and see what works best for you?
[Captivate Android Development] RandomZero:
Will they all work in Canada on Rogers?
[Captivate Android Development] mechanical tool:
Yes, they will all generally work on Rogers. If the modem is not 850 native, you will have to flash it via the special method listed here:

I recommend DVJP9

I'm in australia where DVJP9 is the official modem used by the 2.2.1 firmware released by Telstra

It defaults to 850mhz also which is cool
[Captivate Android Development] shoman94:
Now that I'm back from vacation in my testing grounds..... I am gonna test this modem.

It definitely defaults 850.... no flash trick.
[Captivate Android Development] sicmadek:
meaning it will try to stay connected to 850 before 1900? i would like a good modem that will that so i can just leave it on auto in *#2263#
[Captivate Android Development] andrewdroid:
I'm testing DVJP9 in NYC. Something to maybe help us is to think about which companies have issued which modems. Telstra,the australian one (DVJP9), at least according to Wikipedia, supposedly uses the 850mhz band in their mobile service in Australia.

Where do the other modems come from and what does Aries actually mean? Etc etc.

[Captivate Android Development] fractaline:
I'm in australia, been using jvk for a while now and didn't think it could be topped.....

I've been testing dvjp9 and finally got a chance to take it through a known dead spot. So far only jvk made it through keeping 3g. ... But jp9 kept it as well. To me they seem equal in speed, signal strength, and call quality but I've had the best gps performance with jp9.

telstra uses 850/2100 but the 2100 is negligible, I've never seem my phone go to 2100. so it wouldn't surprise me if it preferred 850.

So fwiw, I think it stands up against jvk....... if only just....
[Captivate Android Development] fatjoez:
Same here I was using UGJL2 for almost 3weeks because of the initial recommendations in this thread

UGJL2 gave me absolute rubbish performance/reliability and I was always wondering why my Telstra Australia Stock firmware of 2.1 had a better modem performance

Now that Telstra has released 2.2.1 using DVJP9 i'm using that modem and the performance is much better

Another guy recommended JVK modem as better performance but I'm not bothered, I'll stick with what Telstra has tested and approved
[Captivate Android Development] LNJ:
I believe JL2 is a Telus modem and when I used it, it was pretty good but I'm in Canada and Telus is a Canadian provider so it's probably tuned differently than a european or Australian based provider modem.

I recently visited my mother on Long Island and was shocked at how horrible AT&T's service was. I switched to JVK - which on automatic connected on GSM 850 most of the time (forcing WCDMA typically resulted in "No Service") - because I could rarely get any connection out of any of the 13 other modems I downloaded to my phone, even my former fav TUBJP9.

no thread that I'm aware of.

I always believed that radios should match the kernel version they're running (kernels could be calling different APIs in each modem version) so i'm running JVK. Battery life has been awesome so far, specially in idle. Much better than having JVK on froyo builds/kernels.

For the newbies to this thread, when people talk about the "Modem Dance", this is what they are referring to: http://xdaforums.com/showpost.php?p=12156313&postcount=438. Since that seems to be a consensus term, maybe the first post should even be edited to mention that ;).

Second question/comment: I wonder if it would help our speeds and connectivity if we disabled the unused bands in our areas. For example, Band 900 and Band 2100 are *not* used in the USA/Canada at all. I wonder if maybe our modems are trying to access those Bands sometimes with "automatic" turned on.
