I'm happy with ubjp9 but flashed dvjp9 anyways. It's been a bit inconsistent for me during calls a few times walking through areas at work where ubjp9 would keep the call steady, also I am noticing slighty higher battery drain but it may be my imagination so will report on that a bit later. Its getting harder to noice any diff. With these modems lately.
[Captivate Android Development] grkmaster:
I flashed and since i did it where my phone has connection to 1900 I got no service on the initial flash. Gotta figure this out. Maybe force it to 850 somehow
[Captivate Android Development] Felixpau86:
Mine won't switch to 1900. It's constantly on 850. Haven't made any calls yet.
[Captivate Android Development] fractaline:
@angel... I hear you, it's hard to tell the difference between circumstances ands modems sometimes.....

@grkmaster

That's what I'm thinking,.... Is that you may have to some how force 1900 if you want it .....

EDIT

My guess would be to use say, kc1 that is native to both 850 and 1900 and enable 1900 before flashing DVJP9.

The opposite to shoman's method. But again I can't test it as I have no access to 1900....

Grkmaster: does it pick up 850 if you move your phone?

I cant test that here as I only have 850. Telstras network.is pretty different from other 850 networks pehaps that could be a problem.
[Captivate Android Development] grkmaster:
I couldnt even get servicemode working to force anything so iwent to jl2 and forced 850 and now flashing back
[Captivate Android Development] grkmaster:
KK so I forced 850 and it worked with a signal and then I went into Servicemode and force 1900 and that worked. Now the test is to see if it switches when i put it back on automatic
[Captivate Android Development] shoman94:
Hmmm I forced it to 1900 and it went. I out it back to auto and it prefers 850. It did switch to 1900 at one point I noticed.

Edit: I'm sitting in parking lot and it switched to 1900. Seems 1900 is stronger where I'm sitting now.
[Captivate Android Development] grkmaster:
I put it on automatic and I switched hands and it switched from 850 to 1900 like normal. So maybe we have to force to 1900 initially then back to 850 to get this working
[Captivate Android Development] shoman94:
Mine worked like normal right from flashing it. Except out seems to prefer 850.
[Captivate Android Development] fractaline:
Well, I can say that so far DVJP9 is equal to JVK in data speeds....

And signal is stronger by a few dbm... Gps faster.

Can't comment on battery life or call quality yet.

Hi. I live in India and here 3g network is still in infancy, I mean roll out is still not complete. All the service provider here have their 3g services in WCDMA2100 band. We have our GSM services in GSM 900(mostly) and GSM 1800 bands.

Most of the times I'll be using GSM services due to lack of 3g rollout.

What will be the recommended modem for me?

I tried 2 of the aries radios and I don't get a ringing noise when i call people but i called my landline and it dialed out and i heard static only on the landline. Is this radio related or is it related to me upgrading to cognition 4.3?
[Captivate Android Development] LNJ:
Cognition is a Captivate based ROM is it not?

So chances are that it has a KB1 based kernel so you can only use captivate modems.

If you have a i9000 based kernel, you can use any of the modems listed in this thread.
[Captivate Android Development] shoman94:
What rom and kernel are you running?
[Captivate Android Development] dspielman:
kernel 2.6.32.9

cognition 4.3
[Captivate Android Development] shoman94:
That is a Captivate based rom and kernel. If you wanna use an i9000 modem then you need to flash to an i9000 kernel as well. If not then your options for modems are limited to JI6, JJ4, and KB1.
[Captivate Android Development] dspielman:
ok the data side is working great so i figured it might have been the rom. I'll flash it accordingly. Thanks!
[Captivate Android Development] dspielman:
I flashed I897UCKB1 and its working great now. Ty!

ive noticed today on dvjp9 my signal fluctuates a lot
[Captivate Android Development] RichMD:
FYI that after I had this working on JQ1 and automatic, I tried another modem finally and lost the ability to select 850mhz. I flashed back to JK4 and still did not have the 850mhz as an option (no *). I flashed ucJI6 and the status said 850 - I didn't try to select it - I think it gives an error if you try. After flashing JK4, I again had the option to select the 850mhz band.

I'm now trying the KC1 modem.
[Captivate Android Development] sicmadek:
Im having the same problem after going straight from jq1 to dvjp9
[Captivate Android Development] RichMD:
Did you try JI6 and it didn't work? I assume if you want to try some other modem that you don't select automatic until you are on the final modem. I had been on JQ1 with automatic for a while. I didn't think to try to go back to 850 only (assuming it was still an option) before flashing JVK which is why I lost the option. I was surprised that I didn't get it back on JK4 though.
[Captivate Android Development] sicmadek:
I flashed ji6 then *#2263* was restricted
[Captivate Android Development] xtremesv:
Maroc Telecom uses 2100 band for 3G so you can go for any I9000 modem you like. You should check your speed with your carrier, modems aren't supposed to restrict your connection. It could be a problem with your specific location.
[Captivate Android Development] LOSTLOGIC89:
Ok thank you so much.
[Captivate Android Development] fractaline:
That is strange, because DVJP9 would certainly default to 850...

But there have been many different reports on keeping 850 through different modem flashes..

I've only need the trick once and have flashed a variety of modems since.

Unfortunately, there doesn't seem to be an answer as to why

It works for some and not others.....

I forced 850 before hand on Jq1 before flashing DVJP9, and then switched to Automatic after wards ( or you can force 1900 first and then do automatic to be sure)
[Captivate Android Development] shoman94:
Like stated in my flashing post... after you have flashed one of the modems requiring my method...for example jvk...then to go to js1 or jpg or jq1 etc.... Doesn't require it impress you go back to say jk4 our something.

[Captivate Android Development] Vivified:
I would chalk it up to user error tbh. I tried shoman's method after having similar success when flashing from the "bridge" modem, JJPD, when this issue was first noticed with KP1 and JPG and have been using it for every modem I've flashed since with no issues whatsoever. I work in the IT Dept where I work and some people just don't know how to RTFM and follow it to the 't'.
[Captivate Android Development] fractaline:
True enough....

Some of the comments I've seen seem to prove that skimming is not the same as reading and paying attention.

I don't want to assume the worst, but it shows that some ppl are just not following the instructions....

[Captivate Android Development] LNJ:
I propose that Shoman's guide be posted on the first page rather than linked in the OP sig line.

If the steps are right there, then maybe newbies will read and follow it the first time rather than just dl the modem of choice and flash and then try to figure out how they fudged up!
[Captivate Android Development] shoman94:
It's linked in the first post at the bottom.
[Captivate Android Development] zerkai:
Maybe the op should make it clear by putting something next to the download link. If I haven't been following this thread, I would think its pretty straight forward to pick a modem and flash.
[Captivate Android Development] H3llstorm:
While it's unfortunate that you work with people who can't read, that doesn't mean people here on the forum are similarly disabled.

As I stated earlier in this thread:

Given the varieties of ROMs, kernels and builds (for example, mine's 1007) - plus what appears to be a cumulative effect of flashing modem firmware (hence the need to flash JK4 and JPD in order to get some modems to connect at 850) - it's not hard to believe that different people can have different issues despite their having RTFM.
[Captivate Android Development] shoman94:
Well yes...like I stated earlier... I don't recommend starting with kc1... You need to start from one of the 4 I have in my instructions. This is why I never updated my instructions that kc1 could be used. I left them the same.... So if people are starting with kc1 then they are assuming and not rtfm. Lol
[Captivate Android Development] LNJ:
That's the problem...it's at the bottom near the OP sig line.

Not near the top where it should be.

A link is an extra step. if the steps were integrated on the post we could eliminate lots of questions.

I recommend above the modem downloads.
[Captivate Android Development] H3llstorm:
I don't know where other people started, but I wasn't starting from KC1. I had already flashed JK4 & JPD at 850 in order to get JS1 to connect at 850 prior to flashing KC1. When I found I didn't like it, I had to re-flash JK4 & JPD at 850 in order to get JS1 to connect at 850 again.
[Captivate Android Development] shoman94:
That's exactly what I was trying to tell you. If you flash kc1... Our any other 850 default enabled modem you need to start over with the procedure.
[Captivate Android Development] H3llstorm:
While I figured that out for myself, it would have been handy to know in advance - and it still has nothing to do with an unwillingness or inability to RTFM.
[Captivate Android Development] fractaline:
right... so I flashed jk4/jpd/jpg...jq1/jpg. then tried kc1, meh went directly back to jpg no prob and have since used jvk and dvjp9.....

so we've had different results from the same (almost) set of circumstances...
[Captivate Android Development] H3llstorm:
Except JPG isn't JS1...

I haven't had problems moving between any other modems, only going directly from KC1 to JS1.
[Captivate Android Development] shoman94:
I'm not saying that there aren't possibilities of other ways working for some... But I'm not gonna post a procedure that only works for some. The whole point of the procedure is to enable 850 on a modem that doesn't have it enabled by default. So for anyone listening... If you flash a modem that has 850 enabled by default...you need to start the whole procedure over. If you do otherwise out may not work. So still at your own risk.....

There is that better? I well edit my procedure in my post.

JVK modem package with Edify script for CWM 3+ / CM7

There doesn't seem to be an Edify-scripted JVK modem package, so I created one. USE AT YOUR OWN RISK.

The attached .zip is the JVK modem from the OP redone for use with CWM 3+ and its Edify-scripted updates. I copied the script, folder structure, and update binary from the cm7-captivate-radio-JL3.zip found in the modems package on TeamHacksung Captivate SF. I did not sign this .zip properly, but I don't think that matters.

Why create this? Because I'd already loaded CM7 and I wanted to experiment with PlumbBob's GPS fix 2.0b11 for JVK.

Hope this helps someone else!

Radio Switching

Thanks for great thread about radios. I came to this thread because of extremely poor download speeds at times around 300kbps, however sometimes download speeds were above 1000kbps.

So I started flashing radios and playing around with the settings. Sure enough some of the newer radios have excellent download speeds.

However, this is my problem no matter what radio I use even the stock radio UCKB1, the download speeds would be fast sometimes and then very slow.

By using *#0011#, I was able to determine the problem occurs when using automatic mode selection the radio or operating system is constantly switching back and forth between the 850 and 1900 bands. The real problem was not which radio but the automatic band selection mode. When using automatic band selection mode, the radio is constantly switching between 850 and 1900 bands. This happens even when setting in my office. I learned the trick in this tread to lock the band to 850 but I don't consider this the best solution. Works great at work, but what happens when you have to hit the road?

At least in my area the 1900 band has extremely poor download speeds, always below 400kbps (sometimes even worse). That is the reason for the extremely poor download speeds when the radio switches to the 1900 band.

Is there any way to improve the automatic band selection to lock on the strongest band or signal? It would be great for me to at least have the radio prefer the 850 band. At least in my area the 850 band has the best signal.

This switching between band in the automatic mode occurs with any radio I have tried including the stock radio.

Currently using TUBJP9 locking to the 850 band because it has the fastest download speeds for me. Battery life is okay about the same as XXJVK.

Thanks

[Captivate Android Development] rootnik:
Playing around with modems over the past couple months, this is how they react with my phone:

JK4 - Well balanced, jack of all trades ;)

JL2 - Pretty well rounded, slightly better signal than JK4 (but lower battery life).

JL3 - Gets a more reliable signal where other modems have trouble. Good GPS.

KP1 - Fastest speeds, even with a low signal. Unfortunately my battery hates it.

JPE - Best battery life, doesn't seem too reliable in low cell signal situations though.

I've concluded that JL3 is best for my phone for everyday use. All of these modems have their perks though, so I keep them available unless I need them.
