I'm living in Brooklyn for a few weeks and completely dependent on my captivate gps to get around. I've tried all of the modems...jk4 was the best, and it got me where I needed to go, but still jumped/tried to reroute from time to time. Finally tried JK3. All I can say is...this is GPS perfection.

How's your battery life?
[Captivate Android Development] Johnston212:
What kernel are you using? I'm on ZKP1 w/ Perception 10.1 and I would LOVE to get even half of your battery life. Let me know any other tweaks you did to improve yours.

Btw, the ZKP1 modem has blazing dl speeds. I'm off HSPA, but haven't touched the 850 controls yet and I've already broken my max dl speed on speedtest. Reached 3.0 for a few seconds on it, nothing has ever gotten to 2.5 before. GPS isn't too bad. Haven't really tried more than just locking, but will see more in time.
[Captivate Android Development] hauj0bb:
I'm unable to use WDCMA 850 band at all on UGJK4, I'm forced to use 1900 band. If I attempt to switch to 850 band, I get no service.

I'm in the raleigh, nc area .. and I've not found a decent modem yet.

Edit: tried UGJL2 and TLJL3 .. unable to use WDCMA 850 band at all .. this is the case for every rom i've used.
[Captivate Android Development] chiefchyno:
+1... I live in the same area and have used the same modems. Is this a network issue?
[Captivate Android Development] Johnston212:
I live in Georgia and was having a similar problem. Try out ZKP1. It has worked really well so far. Sometimes though, you may need to reflash the modem. The First time or two that I tried out ZKP1, it didn't work all that well. I tried it again last night and the dl speeds alone blew me away.
[Captivate Android Development] evrionis:
I have a rogers/captivate running phoenix 4.5 using the default JK4 modem,

is it worth trying the I9000UGJL2 or the I9088ZNKP1 modem's?
[Captivate Android Development] Drew489:
Running the same set up except on att. Tried both modems. Didn't notice any real difference. Ran speedtest and slightly higher on jk4...but could be coincidence. Running jl2 right now actually...nothing different.
[Captivate Android Development] india23:
I am using speedmod's kernel. I don't download much on my phone so I can't vouch for the speeds.
[Captivate Android Development] Johnston212:
Yeah, that's what I'm using as well. I always do a speed test to make sure it will work for me. I use the internet a lot, so the higher the better.

Anyone knows whats the best modem for the 3g 1900 Band? battery life its my main concernt.

No problems with data or static yet.
[Captivate Android Development] mbc663:
agreed, jk4 and jl2 i dont get service inside the hospital i work (small room sort of underground) near philadelphia. JQ1 gets 3 bars and NEVER drops signal there where any other modem was atleast 50% of the time was looking for a signal, killing the battery. idle could be a bit better, but i am on gingerbread so who knows. im dropping about 2% hour idling.

Seems on par with JVK for me.

[Captivate Android Development] shoman94:
for me... ^^it is speed wise but at my work since on GB, ZSJPG has been best with DVJP9 second then XXJVK. I don't know what happened... but the order flip flopped since putting on GB. Now I only had a few hrs at work to play with XXJVO but its been on par with ZSJPG.

They all worked well for voice at work BUT... data is what separated them for me. Poor coverage and least data timeouts.

Anyone have any clue which of these work best in northern virginia?

I'm on froyo.
[Captivate Android Development] H3llstorm:
I've been driving around the RI/MA border since 9:00am (again, delivering Mother's Day flowers), and JVO gave me the best GPS reception/accuracy I've seen on GB, as well as passing effortlessly from EDGE to GSM to WCDMA (E/G/H) all day long.
[Captivate Android Development] Eschmacher:
So i tried out JL2 for froyo, and I now have 3 bars again at work. Seems to be working very well.
[Captivate Android Development] cytherean:
Just flashed JVO. It has 850 band and seems to have accurate GPS. Not sure on the battery yet.
[Captivate Android Development] zuN!:
Could you tell me why switching between E/G/H would be beneficial? If I needed faster data speed wouldn't a modem capable of purely staying on WCDMA be best? I'm on CM7 and we don't have the option of choosing WCDMA only so I'm curious to know the benefit of the network switching.

JVO works very well on CM7 though
[Captivate Android Development] H3llstorm:
Ideally, our phones would connect at WCDMA everywhere, all of the time. Sadly we don't live in an ideal world, and if WCDMA isn't available, connecting to GSM or EDGE is better than no connection.
[Captivate Android Development] Creshaw:
Yeah, it couldn't be written better :D
[Captivate Android Development] H3llstorm:
The only gripe I have with JVO - even after the "modem dance", it's still reluctant to switch from WCDMA 1900 to WCDMA 850.

PS: By "reluctant" I mean "un-friggin'-likely".
[Captivate Android Development] zuN!:
Wouldn't the earlier quote mean that the modem dance isn't necessary?
[Captivate Android Development] :
Meh, back to JQ1 I go. JVO didnt have near the signal strength that JQ1 does. JVO was really clear in calls though, and battery seemed to be ok, but I dont get very good signal where I live and JQ1 does the absolute best for me.
[Captivate Android Development] dizx:
I just finished testing the 2011 modems and JQ1 is the clear winner (on GB), even over my long time favorite JL2 (on Froyo, but also tested on GB).

Even with the modem dance, I'm locked on 1900 WCDMA. It's just my area I guess.
[Captivate Android Development] shoman94:
It switches all the time... when needed.
[Captivate Android Development] H3llstorm:
Perhaps, but it doesn't switch when 850 is significantly stronger than 1900 - which is when I need it.
[Captivate Android Development] shoman94:
It does for me "in my area" ;)
[Captivate Android Development] eliminat:
Dance was required for me going from KC1.
[Captivate Android Development] shoman94:
I think its gonna depend on what modem you have on. It seems the "modem dance" If you are on a North America modem ie KCI, JL2, JK4, you need the dance... but coming from TDVJP9 which is a non-NA modem with 850 by default doesn't require it. This is just what I've seen so far but I haven't tried them all to prove that. Cause TDVJP9 worked the same for me on froyo.... no dance required.
[Captivate Android Development] Loftus:
Your phone switches frequency bands based on thresholds that the network sends to the phone. You should complain to your carrier if you're not happy.
[Captivate Android Development] shoman94:
And I understand that TOTALLY... but.. why is it that some modems seem to switch quicker to 850 then others(meaning it will switch pretty instantly when signal drops below -105 but some others will hold -111 or so for a few seconds before switching) and some when it does switch to 850 hold on to 850 longer than others.
[Captivate Android Development] H3llstorm:
That's my experience with JVO. Using the GSM Status screen in SGS Tools, I've seen signal strength drop to -113 while clinging stubbornly to WCDMA 1900. When I first did the modem dance, it connected at WCDMA 850 in the -87 to -91 range.
[Captivate Android Development] shoman94:
The only time I see the modem change over to 850 at a high signal like that is if the difference between 1900 and 850 is 12 to 15db difference and that does't happen very often. Every modem has been exactly the same in that respect.
[Captivate Android Development] kobik77:
As a CM7 user I can't do the modem dance.

Does JVO and JS1 have native support of 850 band?

I think that the OP should also mention that for each modem.
[Captivate Android Development] {Angel}:
No only the modems from M, B and T variants of the I19000 support the 850 band. For the rest you need the trick.

850 modem problems

I have SimplyHoneyV3.3 runing Gingerbread2.3.3 and tried installing this modem file that definitely does have wcdma850 software in it into my 9000T that definitely has wcdma850 hardware in it (ive used wcdma850 on US-ATT-3G before)

I9000UGJL2 (Froyo)

Download for CWM3 (Gingerbread based ROMs) » modem_cwm3_ugjl2.zip

SP6160_ARIES_DB221110

But when I try to enable wcdma850 under *#2263# it give me "menu does not exist".

I've also tried another ROM - GingerReal. same thing.

The modem definitely gets flashed - under phone settings is shows the JL2.

?
[Captivate Android Development] eliminat:
If you've read father back in the thread you'd see he's trying to get rid of the poll completely. It's an old poll, and other options such as kc1 weren't around yet.
[Captivate Android Development] eliminat:
Enable it under combi-bands first, then go back and try selecting only 850 under WCDMA.
[Captivate Android Development] zuN!:
Continuing...

Really now? I would like some clarification on that :)
[Captivate Android Development] {Angel}:
Clarification on what exactly?
[Captivate Android Development] eliminat:
With JVO today I've noticed I haven't been able to get GSM to connect, just 3G or nothing, and had to go to Flight Mode and back once when I had signal, but data stopped working.
[Captivate Android Development] zuN!:
Forgive my ignorance but I'm assuming that a modem has 850MHz native support if the modem dance isn't required. Concerning JVO, I've quoted some posts which stated that the dance wasn't required.
[Captivate Android Development] alexige:
I'm not entirely sure but in my playing around with modems it would seem that JVO from what i remember I needed to do the dance to get it to work. I think I tried going straight from JK4 or TL3 and was unable to get 850 to work.
[Captivate Android Development] shoman94:
Its not required if you are coming from an i9000 modem with 850 enabled. For example, Continuum v5 comes with TDVJP9 which is i9000 with native 850 support. I can flash xxjvk or xxjvo or zsjpg and not need the dance.
[Captivate Android Development] kobik77:
Is jvo recommend over kc1?

If that so, I will try to flash jvo over kc1.
[Captivate Android Development] shoman94:
I haven't tried flashing JVO over KC1. That one might require the modem dance in my signature.

But you can try it. This is assuming of course that you need 850mhz to work.
[Captivate Android Development] someonemx:
I'm currently on jvo on gingerbread and it holds on 850 mhz according to *#0011# even when 850 band is not selected under combi bands.

At the moment with 3 days of usage JVO seems good overall, great data speed, nice call quality and great on battery.
[Captivate Android Development] BTTNext:
Is there a way to check what band the phone is using on non-Samsung ROMs?
[Captivate Android Development] gospeedgo:
Any luck in your quest to resolve this?

I just got a new phone due to warranty repair and I'm seeing this issue on the new phone. I didn't have it with my old phone.

I'm running Cog 4.4 at this time, but this is the first time I've seen this issue.
[Captivate Android Development] lanisan:
Modem Frequencies

Gonna stretch my luck here ... (slightly winces)..

Is there anywhere that shows what bands each modem uses?

I am in an area that has 1 HSDPA band (1900). There is no 850 here.. well it's in use by a competing carrier.

Additionally since flashing to GB I cannot use the *#0011# command.. get an error of "Connection problem or invalid MMI Code" ... any thoughts?

Thanks
[Captivate Android Development] kobik77:
Apparently modem dance is required.

So I'll stick with kc1 as I do need 850 band.
[Captivate Android Development] zuN!:
Seems like there's a lot of echo and people can't hear me well with JVO. I'll try out TDVJP9 since shoman says that has native 850MHz and is supposedly good on GB
[Captivate Android Development] {Angel}:
Thats correct a real 850 modem does not need the dance. As i stated all M, T, B versions of the I9000 ship with 850 modema. If its tje I9000 international like JVO you will need the dance.
[Captivate Android Development] shoman94:
You don't need the dance if you are coming from the modem versions you stated above.

WiFi Broken

I flashed JVO from KC1 and since then I can't get wifi to work. It connects to my router but keep getting no data transfer. I've tried flashing back to GB stock and reload everything but still no good. Where did I go wrong and what can I do to fix it?

Thanks in advance...

Never mind. I wiped Dalvic cache and it's connected.
[Captivate Android Development] Ranulf WolfSage:
JP9 to KC1?

I'm considering giving Continuum a shot, and notice that it has the JP9 modem. I will obviously give that modem it's chance as far as GPS accuracy and sound quality. In the past however, my GPS has been AMAZING with KC1 on froyo, the best I've EVER seen the Captivate GPS perform. If I ended up wanting to test out KC1, would I need to do the modem dance? From what I understand, I could just flash it over JP9, but I want to make sure before I try. Thanks for the advice! :)
[Captivate Android Development] Eschmacher:
Can someone explain what the "modem dance" is please?
[Captivate Android Development] Ranulf WolfSage:
It's the procedure detailed in the OP by shoman to get modems to use 850 MHz band where without the 'dance' they would tend to run at slower speeds. Look for text below in the OP and click on it for the instructions.

Flashing the JPG, JQ1, JVE, or JS1 modem?

shoman94's instructions how to properly
[Captivate Android Development] {Angel}:
In a way it just might be a shorter dance. But its not or shouldnt be 850 enabled by default. I just updated to jvh from froyo using ubjp9 and can confirm that jvo is connecting to 850. im giving it a.try so far so good.
[Captivate Android Development] rivera151:
+1 on this.
[Captivate Android Development] Oxicottin:
Ok, I have tried many ROMs and modems and I think the best modem for me was the one in Cognition 3.4 "I896UXJL1" is there a I9000 modem that is exactly the same? Thanks!
[Captivate Android Development] mbc663:
Your just listing the baseband version. Jl1 is flashable on any rom.
[Captivate Android Development] Oxicottin:
Your saying its flashable to any ROM like 2.1 and 2.2 right? If so where do I get a CWM USA version. I used the search and I just basically get cognition results. Also, what I9000 modem is basically the same so I can try it. Thanks!
[Captivate Android Development] mbc663:
Dunno how many oxys ur on but its the first page of this thread, the one u posted in. open rom manager and look at what version clock work u r running and download the appropriate zip from the OP and flash just as u would a rom. Depending on your area, u will get different results. Jk4, jl2, jq1 seem to be some popular ones in the states all though I don't believe jq1 defaults to 850mhz, you need to do the "modem dance" to get the i9000 based modems to select wcdma 850. Hope this helps.
[Captivate Android Development] alexige:
I think you might be out of luck. I9000 roms require i9000 modems. I896 modems will not work with I9000 roms. Play around with I9000 modems by flashing them through CWM and see what you like best.
[Captivate Android Development] sicmadek:
I need a lil help from the modem gurus. Everytime i go into low signal area i end up with no service but all of my friends with iphones are sitting there with 2-3 bars.

JVO gave me EDGE rather than no coverage in the RI/MA area.
[Captivate Android Development] sicmadek:

[Captivate Android Development] :
A few guys in your area said that JK4 was pretty goo too, might give that one a shot if JVO dosent work for you.
[Captivate Android Development] sicmadek:
Yea i downloaded a few to try. I forgot to mention im on serendipity 6.4. Have you noticed the modems to work better on gb roms?
[Captivate Android Development] :
I tried them all and JQ1 treated me the best. I jumped from Serendipity to GR 9 (which is a GB rom) and it came with JK4. JK4 was pretty good for me, but JQ1 was still the king. Thats when i realized that the modems worked the exact same on both versions of Android.
[Captivate Android Development] H3llstorm:
JQ1 was the best GB modem for me - until I tried JVO.

JVK was the best modem for me on Serendipity, but not so great on GB.

[Captivate Android Development] nappent:
JL3, JVK, and JVO all work well from me around Seattle. JVK gave me the best data speed but JVO seems to over the best battery life with very slight decrease in data speeds. It's been about 4 months since I've used JL3 but I never had any problems with it. It just doesn't compare with data speed like JVK and JVO.

After doing the modem dance (http://xdaforums.com/showthread.php?t=1042113), i am no longer able to enable HSDPA. In the servicemode menu, i can see the two 0s next to HSDPA and HSUPA, but enabling them in the other menu doesn't change these numbers. Weirdly though, whenever i go on the web, HSDPA turns back on (definately). The bad part is, after flashing to CM7, HSDPA no longer works at all.

I've looked at literally every thread that mentions HSDPA on the galaxy, but none of them were useful.

Any ideas on how to enable it properly (on stock rom)?

[Captivate Android Development] :
Here ya go, this link will take you to the correct page for the JVO modem.
[Captivate Android Development] zerkai:
UBJP9 is best for me in Seattle. JK4 does a great job holding onto calls, but it seems as though during times it typically "should" drop a call it replaces that moment with static. JVO holds onto 1900 more than it should, it would rather fail to send a text or make a call than switch to 850 for success. JL2 is better than KC1 for me in terms of call quality and reception.

My preference: ubjp9, jl2, and jq1.

The "dance" required jjpg is good too. Jq1 also requires the dance BTW.

What was the biggest difference you noticed between JK4 and KC1? I am getting about the same speed and battery life out of both. Will try phone calling in a bit to see if it is better. JK4 always seems to be shallow. I don't have any static but I turn up the volume all of the way but it sounds like someone is talking quietly on the other end.

Did the dance and using JQ1 now. So far, so good.
[Captivate Android Development] mrhaley30705:
If it is a cwm2 zip, you should be able to flash it. You will probably have to do the modem dance to get 850mhz to hold. I dont know that i would try any modem outside this thread. Could have very undesirable consequences.

Perka's File Stash

Ok, I have been using the JVO for two days it was on "Automatic" so I changed to 850 only and its been working great, voice sounds clear and battery is good and my GPS lock is good. I found a link to a "Perka's File Stash" which has a lot of 19000 modems and 850 enabled modems for DL can I use them on the captivate running 19000 kernal? They are CWM files but some of them are CWM3.

I also found an app in the market called Perkas Stash which lets you DL these files on your phone. The free is limited to 10 DL a month and the pro is only .99 and well worth the $.....

Thanks,

If everything is good with JVO why change?
[Captivate Android Development] Oxicottin:
I'm not changing from JVO just stating my experience with it to help others and I haven't tested modem but two days so I might change because where I live there are a lot of hills and I haven't really been in the valleys yet also, JVO isn't in the first post of this thread

that I have seen

and going threw the files I thought some were missing from this thread so I posted the link to help others...
