pretty sure i pulled mine from a rom now that i think about it. just looked again and couldn't find it. uploading it to mega atm though
[Captivate Android Development] Killemalll:
How do you flash the JPK modem with ODIN? The PIT file is 803? Where do I load the .tar.md5 file?
[Captivate Android Development] wmwilker:
just flash the modem in the phone slot and nothing else. Do not check repartition.
[Captivate Android Development] Killemalll:
Ok. Thanks! The PIT file is 803 for the JPK firmware. So I'm assuming for flashing the modem alone should be the same.
[Captivate Android Development] driike:
i flashed no pit, just the modem and it has run perfectly fine =-)

there is now a link for the modem on the main dev page for any who would like it

This is pretty interesting stuff.

It only took me a couple of hours to decide the JPM was not working out for me, and I went back to Cognitions version. I hated to do it as I was loving the theme, and the voice dialer.

But over the past weekend, I flashed deviant's "Fully Loaded JPK\JI6 rom with 2e kernel (10-23-10)" and have had great voice and data signals ever since. (I live in South Alabama).

If this works I will be a happy camper. ;)

After spending most of last night flashing and testing different modems. I ended up getting to a point were it didn't matter what modem I used I was getting zero signal. I ended up flashing Cog beta 9 but my phone was extremely unstable but I had a signal. I flashed the CDE ASOP beta 3 back(what I was using before I tried the i9000 roms). Then flashing the reorient kernel. Now I have working signal, good gps and vodoo lag and color fix. I am happy now till the source is released. Guess now would be a good time to try my hand at themeing.
[Captivate Android Development] clrana9017:
T-Mobile's 3G uses 1700 MHz for downlink and 2100 MHz for uplink. Well, this is going off of knowledge from 2007 when 3G was still in trials. Also, Vibrants work on AT&T 3G because it has 850 MHz support, IIRC. All Galaxy S phones are tri-band 3G/HSPA.

From my experience, the JPM modem simply does not do it for me. It does not connect to 850 MHz whatsoever, even after enabling it in the settings. I need the 850 MHz to connect to 3G here because the 1900 MHz is weaker and 850 MHz overlay is so much better.
[Captivate Android Development] Scottbg1:
JI6 modem is the ticket so far.

I flashed Tayuyama's JPM after a fresh stock 2.1 install, using CWM, and then turned right around and flashed a JI6 modem zip I found right after, and then allowed it to boot up. It nailed 3 "H" bars instantly. The acid test will be when I go outside the city limits this afternoon, and outside the 3g coverage area.

This camper is happy..........so far.
[Captivate Android Development] wmwilker:
I don't think the JI6 2.2 modem supports HSUPA
[Captivate Android Development] boomerod:
I read somewhere they weren't using the 2100 frequency, but that could be incorrect information. Also, DG noted in one of his posts on the Cog thread that a modem he tried briefly - I think in Beta 7 - was able to work on T-Mobile's 3G network. That was interesting news....would sure like to know it that, in fact, is true. But, even if it were true and, for instance, I dropped AT&T, unlocked my Captivate and went over to T-Mobile, the battery drain would be an issue.

---Edit---

Here is the post from DG about the JI2 modem being able to get on T-Mobile's 3G network: http://xdaforums.com/showpost.php?p=8748010&postcount=4853

Yes, my recent experience with the JPM modem is similar to yours. When contrasted with the JG8 modem, in Service Mode you can see that it does not allow you to select the WCDMA 850 band under WCDMA; just under Combi. That leads one to wonder is the Combi misleading.

The problem with the JI6 modem is you will, eventually, get FCs and/or soft reboots when it tries to connect to 1900 (I believe).

Yes, the JI6 modem will run HSUPA; the kernel controls whether it's able to or not.
[Captivate Android Development] chrisryn:
Which JI6 I am using the one that comes with cog beta 9 and don't get hsupa or FC's I do have the re-orient kernel is there two different types of JI6.
[Captivate Android Development] boomerod:
OK, I could be wrong...what's your speed test giving you?
[Captivate Android Development] chrisryn:
down: 1507 kbps up: 360 kbps
[Captivate Android Development] Pirateghost:
in my experience, JI6 DOES NOT have HSUPA support on the modem.
[Captivate Android Development] boomerod:
OK, that's technically borderline HSUPA...but, certainly not what I've seen on modems I am sure support HSUPA.
[Captivate Android Development] pb1866:
I tried flashing the JI6 modem from the captivate and definitely lost hsupa speeds... I'm guessing the hsupa code is in both the kernel and modem.

[Captivate Android Development] Scottbg1:
Boomerod is correct, atleast in my case.

My joy was short lived as my phone became almost unusable with FC's, and reboots.

Strange thing is, I noticed that I only had trouble when I unplugged my phone. Hence my excitement for the first hour or so I was messing with after flashing, I had it plugged in the whole time.

My troubles started after I unpllugged from the charger. When I got to work last night, after plugging up to my pc to wipe and reflash, it settled down and worked as it did when I first installed the modem. I unlugged it, and it was fine until I opened an app. And then it went haywire yet again. Plugged it back up, and so on.

So I went back to Cog's beta9 until I find that perfect ROM that works flawlessly, whilst having all the functions I desire.

Truth be known, if someone would port froyo's voice dialing over to eclair, (if thats even possible), I would be quite happy running that. As far as reliability, I have yet to flash a rom that is as smooth, and responsive as stock 2.1 with "unleash the beast". Other than the obvious uses like texting and phone calls, and light internet surfing, I use my phone to pass the time at work by playing games. Ive tried tons of different roms with all the must have lag fixes, and my games are no where near as smooth as with the aforementioned 2.1.

But you have to flash, right? Whenever a new one comes out, its like a carrot swinging in front of my nose. Past experiences dictate I will be let down yet again, but if I don't try it, what could I be missing out on????? ;)

Carpe' Diem my fellow Android Brethren.
[Captivate Android Development] l7777:
so does anyone actually have the JPM modem connected to the 850 WCDMA band? I got the e-mail issue sorted out on my phone so I'm running Tayutama's rom attempting and can confirm that I am unable to connect to the 850 WCDMA or GSM bands.
[Captivate Android Development] tjsooley:
I have seen a lot of Clams but no screenshots proving that his baseband is connected to this band.
[Captivate Android Development] newter55:
I can do it connecting to gsm850 but cannot test wcdma. I live in edgeland until January (yeah right ATT I will believe it when I see it :cool:) I was running Tay's rom connecting to GSM 850 and 1900. I had to have the 850 band as it is all that is usable at my house as I can barely pick up the 1900 band there.

Steps that I take are Flash to stock, flash jg8 modem, cwm to tay's rom. I have no explanation why but the flashing of the jg8 modem is something I tried when I spent half a day trying to find a modem that would connect to my gsm850 and nothing worked regardless of the settings I changed. It seems as though it does something that keeps the 850 band enabled.
[Captivate Android Development] l7777:
What modem are you using and how did you confirm 850? Quite interesting. I was going to try the jg8 modem sometime anyway to see what would happen. I'm now using jpk and if I chose 850 GSM only, I get no service. The 1900 Mhz signal is more stable than with JPM, but still no 850 anything. 850 and 1900 are both deployed here and while 1900 can provide better speeds, 850 provides better coverage as it can better penetrate obstacles since it's a lower frequency.

If anyone wants to play with different modems, I created zips of several 2.2 and 2.1 modems. Apply with CWM. Standard I am not responsible for what happens if you use them disclaimer applies.

JPK, JP6, and JPA are 2.2 modems

JG8 and JH2 are 2.1 modems

When 850 can no longer be connected to, even though you know its there, this process is needed to restore it.

Sent telepathically using vulcan mind meld app.
[Captivate Android Development] l7777:
Yes, I see what you both mean. My solution:

Make CWM backup of Tayutama 1.0.3

Applied Cognition 2.1.7 with CWM

Verified working 850 band

Applied 2.1 reorient kernel and JG8 modem with CWM

Re-verified working 850 band and forced to WCDMA 850 only

Modified Tayutama 1.0.3 ROM package with JG8 modem

Applied Modified ROM with CWM

Again checked that I was still connected to WCDMA 850

Restored CWM backup

Obsessive compulsive checking of WCDMA 850

Applied JM8 modem with CWM

Used service menu to make sure all bands were available.

Walked down to the basement where WCDMA 1900 is very weak, automatic switch to GSM 850. Upon walking up the stairs, I saw WCDMA 850 connected for a bit and then back to WCDMA 1900. Before taking the above steps, I couldn't even force any 850 connections on either GSM or WCDMA. Now I've seen both automatically selected. The real test will be when I go home this evening as WCDMA 1900 is pretty weak there and the AT&T modems switch to WCDMA 850.

My guess is that anyone who absolutely can't connect to the 850 band will need to return to a 2.1 ROM with JG8 modem, then flash to a 2.2 ROM with JG8 and then to an official 2.2 modem.

Ok, I just borrowed my co-worker's stock captivate and held them side by side with the basic information screen on. They both had nearly identical signal and both switched seamlessly to the 850 WCDMA and then to GSM at the same time when I took them down to the basement. It appears that going from 2.1 to 2.2 in sequence is key to keeping the 850 band working.

[Captivate Android Development] Killemalll:
I followed the flashing sequence you suggested in a previous post. OOC JI6, all bands enabled, flashed Tat 1.0.1, all bands enabled, flashed 1.03 patch, all bands enabled.

The phone used GSM 850 band last night when I was at home, switched to WCDMA 1900 today at work. I'm back home, and the phone is using now WCDMA 850 inside. If I walk outside, it picks a better 1900 signal and switches.

Thank you very much man for figuring out this trick! This is awesome. I can finally enjoy HSUPA.:D

It's still not clear how flashing JPM over JG8 produces such different results than going straight from JI6 to JPM.
[Captivate Android Development] boomerod:
I thought about that. In terms of JF6 vs. JG8 the only glaring difference is one is designed for Captivate and the other for I9000. Also, I think that somehow we are not getting truly clean flashes.

[Captivate Android Development] Killemalll:
The phone is actually using WCDMA 850 now at my house. It was on the GSM band for hours last night. Kinda erratic behavior. I any cases, now i have full bars at home. It never happened before, not even with Eclair.
[Captivate Android Development] l7777:
Absolutely we are not getting clean flashes because we are not really flashing. While the kernel and modem are indeed flashed, the rest of the Rom is more like an OS install than a flash. Not knowing what goes on during the semi-first boot, I suspect that is where the difference lies. The question is what does it change that isn't touched by a CWM backup since my restoring a backup didn't break my 850 band again.

At least as it is we can get people going. Maybe we'll eventually figure out what is happening behind the scenes.

[Captivate Android Development] raychang:
I noticed in the Service Mode menu there are two items, [3] UMTS RF NV and [4] GSM RF NV. I tried to get into [3] for either Read or Write, but it does not allow me and said that the menu does not exist. From my guesses, the NV means non-volatile memory (just like where SIM lock is stored). Since the menu does not exist, it indicate that from other places (data or other menu), one can set the value of the NV memory (just like how we use COMBI to add WCDMA 850 band for the menu not exist in WCDMA 850 sub-menu). I think some data/info in the rest of the ROM has some directives to inform the CWM whether or not to clear the NV memory. The author of the CWM (Koush) should know which data/info is. I tried to use CWM to install the Shep211's stock I9000 ROM (using JPM modem) after a fresh installation of stock JF6, the WCDMA 850 does not work. That means some info in the ROM ask CWM to clear the NV memory. If Koush can help, that will be great.

You missed a, presumably, critical step. If you read boomerod's post that is linked in mine, it discusses the detail that you must flash from a 2.1 ROM with the JG8 modem to a 2.2 ROM that also has the JG8 modem before applying another i9000 modem. I modified tayutama's package that I had, but if you don't want to do that, follow boomerod's posts and he'll give you a link to Tayutama's 1.0.1 package that has the JG8 modem in it. You can then jump from that to the JPM modem. You also will not see WCDMA 850 if 1900 is good and strong or if it isn't in your area. Only way to know what you should be seeing is to note what is being picked up by the stock ROM. You can use the band selection menu to force WCDMA 850 while on JG8 and confirm it is available. Most of us that had trouble with this had both 1900 and 850 available, but 1900 was weak and couldn't be used or was sucking a lot of battery power trying to maintain a connection.
[Captivate Android Development] cnewsgrp:
Thanks. I see your point. For a newbie like me all this seems very complicated. The phone seems to be working well for me and I will hold off flashing another ROM till I see a stable one. I have done too many ROM changes in past week and don't want to challenge my luck and brick my phone.
[Captivate Android Development] l7777:
Don't let the complexity scare you, as a noob, I would recommend following the guide laid out by boomerod in this thread

http://xdaforums.com/showthread.php?t=816271

If you follow that step by step, you should be in good shape. Now that we're using clockwork recovery to apply ROMs, truly bricking your phone is difficult. At worst you'll have to go back into CWM and restore a backup. You are making backups right? ;) At this point, the most difficult thing is getting people to disable Voodoo before attempting to change ROMs or Kernels. Even that is becoming less of a problem.

[Captivate Android Development] thekurrgan:
Because the question was asked earlier if GSM was used for voice I feel that statement is missing a bit..

WCDMA (Marketed as "3G") is its own platform. It carries both voice and data. It is a common mis conception that AT&T / T-Mo use both bands (1 for voice, 1 for data) because of the fact they can do voice / data at the same time. Fact is, the reason they can do both at the same time is because the channel is wide enough, allowing them enough bandwidth to carry on a voice call + a data stream at the same time. Verizon / other "3G" CDMA carriers, use a 1mhz channel spacing which is insufficient for both at once.

When an AT&T/T-Mo phone is in WCDMA mode, it uses THAT for all traffic. GSM is MONITORED, but not used. This is primarily for fall back purposes should WCDMA become unavailable or move out of range, thus allowing a hand off mid call to a GSM tower.

In short, WCDMA (3G, NextG, HSPA, UMTS, whatever) does both voice and data.

Here are some of my questions

1) Do we need to flash to stock JF6 using odin for ROM flashes? I do that always. I lose 3 button recovery when I do that and need to flash the fix. Going forward I was thinking of flashing this rom if I need to flash to stock.

2) Is there a thread that explains what is Clockworkmod recovery and how is it different from recovery? I looked up this thread here and while it explains how to backup using CWM

3) How to you "recover" from a bad flash using CWM
[Captivate Android Development] mcx6:
All you have to do to restore from a bad flash is boot into CWM go to backup and restore using volume rocker then click power button to select, then choose restore option and it will show your backups, just choose the one you want and your good to go. Hope this helps.
