I'm running JPG right now. I'm currently on 1900, but was on 850 all day. JPG works great on 850 for me, and I have never flashed JL2. Not sure why some people are having to jump through hoops.

I am able to directly select 850 from WCDMA bands, or in conjunction with other bands in combination. In both cases the phone switches properly. The only thing I have done is to keep WCDMA 900 disabled.

I was using KP1 and JVE previously. I flashed to JPG from JVE to the best of my knowledge.

and is the battery better than JK4/JL2?
[Captivate Android Development] shoman94:
Yes.. also faster data, better data transfers at 1 bar(-110 to -105db), also I was talking inside walmart with no bars... signal bouncing between -115 and -110db. This never happened with any other modem. Would always drop the call.

you came from KP1... thats why.... I did the same.

JQ1 modem.... I'm downloading now and will check it out.

The JS8 base.... maybe icezar1 should look at this before his JS7 release.
[Captivate Android Development] Cezar`:
I will for sure ;)
[Captivate Android Development] harpo1:
Gives us the skinny. Speed test, band selection, etc......
[Captivate Android Development] doreyu:
From your sig:

Did it connect to the 850 band?
[Captivate Android Development] mechanical tool:
I installed JPG using the JL2->JPD->JPG and 850 works well, although it does seem to prefer 1900 in areas where JK4 would use 850. JPG will switch over to 850 pretty easily though.

My testing has been by no means scientific, but ive found the battery drain on JPG to be very low while idling but seems much higher while using data. Maybe i just notice the drain because the idle drain is so low.

Yesterday I went 14h unplugged and had 71% left with 50 minutes of screen time. Most of the data was used through wifi (~5h).

Today 12h unplugged and i at 56% remaining with 50 minutes of screen time. No wifi was used today. Its not a direct comparison as I was in a different location today so signal strength wasn't the same.
[Captivate Android Development] perosredo:
It put me on 850 Band 5 by default.

No other impressions yet.

EDIT: First, impression: lowest speedtest I've seen yet (.25dn/1mbps up)--but it is primetime.
[Captivate Android Development] shoman94:
Speed is a little better than JPG.... about 200kbps on DL and 100kbps UL. This is an average. 3.5dl and 1.5ul

Yes coming from JPG with 850 working.
[Captivate Android Development] shoman94:
The WIFI data will use less battery than 3g when data is in use..... at idle 3g uses less.... main;y because wifi scans for wifi access points every 5-6 seconds. Di11i rom version 7.1.1 has changed that to 32 seconds.... this is the only rom to really fix this so far.
[Captivate Android Development] shoman94:
I was seeing a bit better.... an hour ago.... will test again later out of primetime.
[Captivate Android Development] devz3r0:
Added the JQ1 modem to the OP.

Getting average speeds now 1.5-2.5 down and 1.5ish up
[Captivate Android Development] shoman94:
Important: Do not flash the modem with the phone plugged into USB or the charger. It could cause a no service at restart.

Also if you don't have 850mhz and don't give a crap about 850mhz, then don't do this. Just flash to whatever modem you want.

Another note: If you flash a modem that has 850 enabled by default...you need to start the whole procedure over. If you do otherwise it may not work. So it is at your own risk.....

You need to flash or be on (UGJL2, TLJL3, UGJK3, UGJK4) and enable 850mhz ONLY by going into the dialer and type in *#2263# select WCDMA and select 850mhz. Boot into recovery and flash (BVJJPD or BVJJPG). Boot up and type in the dialer *#0011# and verify 850mhz. Reboot into recovery and flash (XXJVK or ZSJPG or XXJQ1 or BUJS1 or XXJVE etc). Boot up and verify 850mhz by entering *#0011# in the dialer. If you don't have 850mhz you did not do it correctly or your phone/ROM doesn't like the modem.

Once you verfified 850mhz above, go back into the dialer and enter *#2263# and select automatic then select menu> back. Then select combi bands and then select to add wcdma850. Now select menu>back and verify the * is next to all bands. IF so Press the back to to exit and let the modem do its job.

At this point more than likely the phone will stay only on 850mhz until you reboot.... then all the other bands will work properly.

PS: If you already have JPG, JQ1, JS1, JVE, working on 850mhz, you can flash to any of them without using the whole process above. Just flash.
[Captivate Android Development] :
Does it have to be the regular JL2 or can it be the armani JL2?
[Captivate Android Development] shoman94:
Yea... its the same.... someone just named it different
[Captivate Android Development] WoodPusher:
SO has anyone tested XXJQ1 yet? How does it compare with JL2?
[Captivate Android Development] ewingr:
Try this. I'm pretty happy with it.
[Captivate Android Development] WoodPusher:
can you flash JQ1 directly and get 850 ?
[Captivate Android Development] eliminat:
JQ1 seems to be really fast, and better signal, but I haven't had a chance to test in low signal areas yet. That'll probably be this afternoon.

850 was enabled coming from JPG for me.
[Captivate Android Development] WoodPusher:
Is the flash order required like with JPG?
[Captivate Android Development] madmack:
I know this might be a bit too early, but can you guys post your first impressions on battery life with JQ1 ? idle/not idle.
[Captivate Android Development] MaxRabbit:
It really annoys me that JPG requires this process every time I upgrade Continuum.
[Captivate Android Development] phlunkie:
Highest downloads speed i have ever had, is on jq1. Finally got 3.2 megabits/sec. North Orlando. Not sure on call quality/gps/battery yet. Running latest romkitchen i900 js8 with paragon1200. Bluetooth sound works for music. Will edit later with other testing results.
[Captivate Android Development] DDNV:
Was for me. Tried to cut corners but didn't work.

Very subjective, but seems to working well for me.

DDNV
[Captivate Android Development] phlunkie:
Agreed. i had to go through the steps. i went straight from jl2. It got stuck in g. Had to follow the sequence.
[Captivate Android Development] shoman94:
No unless you are coming for JPG or JVE with 850 working

Yup me too

Yes required

Actually I went from 3.5Beta to final....I change the Modem.bin into the final zip file so I flashed final with JQ1 in it. Worked great.
[Captivate Android Development] MaxRabbit:
I tried doing this once, but when I zipped the ROM back up, it wouldn't be recognized in CWM. Any tips?
[Captivate Android Development] xtremesv:
Same happened to me on my network.
[Captivate Android Development] shoman94:
I use winrar for zips... I open the zip using winrar.... open open the folders to where the Modem.bin is.... then open the modem zip. Same thing...open to the modem.bin then drag the modem.bin file from the modem zip and drag it into the rom zip where the modem is located. pop up... say ok.... then close winrar and you should be set.
[Captivate Android Development] shoman94:
It needs to be flashed using my method above.
[Captivate Android Development] jaxf250:
Thanks shoman - followed your sequence and now have JQ1 working on my Cap. Will be interesting to see if this does better for me here in No. FLA than JK4 has.... getting a lot of dropped calls lately and hoping this new modem helps with that... data speeds seem great at first test. I hope call audio quality is impressive as well when I test it tmrw.
[Captivate Android Development] shoman94:
Just so you are aware.... I would recommend JPG above JQ1 currently as I haven't tested enough to conclude. SO far JQ1 is on par.... I need to head to my spot that JPG holds onto and call with no bars with the signal bouncing between -115db and -111db. No other modem has been able to do that for me.

Today I saw -118db during a call on the road but it was only for 2 seconds then it started to come back up. I was clear and had one slight blurp when I saw it hit -118db but held onto the call no problem. In that location I've had every phone I've owned drop a call there.

Definately test it though... if that doesn't work out... just flash back to JPG and try that one. I'll be in Florida in a few weeks so I'll be able to test these modems in central FL for a couple weeks.
[Captivate Android Development] NISMOFO:
Is anyone running Cognition from DG? If so what is your modem of choice (and Kernal)?

I have used Speedmod + JK4 and it was faster for sure (especially the UL speeds), but not too sure on the battery life.
[Captivate Android Development] dmnall:
Well here are my findings so far tonight with jpg and jq1 and even kp1 modems. I was not getting 850 mhz bands at all on all 3 tonight, but with Jk4 it was running fine *at my house I can only get a very week 0 bar on gsm 1900 band even doing the same when trying to go back to kp1, but with jk4 I was grabbing 850 mhz Edge *2 - 4 bars* and 1 bar on HSPA network.. flash to either jpg or jq1 = 1900 mhz band until I switched back to jk4, then kp1 everything works perfectly.. Now running jq1 but I cleaned the Dalvik Cache before I rebooted the phone, 850 mhz band and works great. So try cleaning Dalvik Cache after flashing and see if that works for you. GPS under jq1 takes around 36 seconds to lock on indoors. Not too bad in my opinion but could always be faster, but I am going to test this one for the next day or so. Also forgot to mention that I am running phoenix ultimate with Suckerpunch #7 Kernel with Voodoo enabled.

Cheers,

Charlie
[Captivate Android Development] akuru:
No GPS connection after flashing kp1, jq1 or jl2

My Captivate was on jl3, but the reception was not satisfactory so I decided to try alternative modems listed here.

I've tried kp1, jq1 and jl2 so far. Although GSM, UMTS, BT and WiFi is working fine with these modems, I couldn't get the GPS working. Almost no reception at all with all of these modems on open ground and under clear sky! Waited more than ten minutes, caught only 1 or 2 satellites at best. Never able to get a fix.

With all modems I've tested, I've cleared the dalvik and main cache through CWM after flashing. Is there any other special steps to take before getting GPS to work? Can anybody tell me what I'm missing here?

Here are some details about my configuration:

Location: Turkey.

ROM: Darky's v9.3 (Froyo v2.2.1)

Kernel: Speedmod K13c 500hz

Thanks in advance!
[Captivate Android Development] MaxRabbit:
Thank you!
[Captivate Android Development] johnsonxray:
lol can anyone come to an conclusion JPG or JQ1 performs better in battery life? as in idle and usage? JPG saves more battery? or JQ1? I don care about GPS i seldom use that my main concern is battery life lol
[Captivate Android Development] jayjr1105:
I finally got my captivate unlocked for tmobile. Do I need to use vibrant modems or are they the same?
[Captivate Android Development] caanda45:
Looking at all the modems is there any pattern or coding to them for compatibility etc. and what goes with what? I have used I9000UGJK4 (Froyo) and it worked well but had huge issues with my in car bluetooth from Parrot a MKi 9200. Now I am on this modem T959TLJL3 (Froyo) and this one seems to like my bluetooth much better.

So any way to figure out what to try and what not to try? Rom is 2.6 FireFly, Kernel is 2.6.32.9 speedmod i-897-kc13 #28 and of course the T959TLJL3 . Just trying to understand the numbers and what goes with what. The other aspect that I am toying with is using SuckerPunch-Voodoo #9[Sound v5, Lagfix, Color & Sharpness][UV Support] kernel. So any advice would be appreciated!!!
[Captivate Android Development] WickedNite:
Using JQ1 now, reception and data speed seems great. Let's see how it performs regarding battery life.
[Captivate Android Development] WoodPusher:
ok so I have JPG on 850 working. I already went back to Automatic in band selection. If I want to go to JQ1 can I just flash on top or do I have to repeat the process?

thanks!
[Captivate Android Development] Pierce533:
I'm looking forward to reading your results. I know it is early, but what is your impression of this modem compared with UGJK4, if you have used UGJK4 before? If not, then please ignore this message. ;)
[Captivate Android Development] WickedNite:
I used JK4 before but that was like a day or 2 only. I don't know but JL2 performs better in terms of battery life for me. So right now, I'm testing JQ1 and see it if performs better than JL2.
[Captivate Android Development] Pierce533:
Ah, ok, thanks for the response. I used JL2 for about a day and had to return to JK4. AT&T signal in the Seattle area is sucky, from my experience, and so I am always looking to improve signal. I'll have to give JQ1 a trial run to see what it does.
[Captivate Android Development] harpo1:
Voice quality is far superior to JK4 in the Northern California area. Even in my house where I get terrible reception. So far I'd compare this modem to JPD and JPG in voice quality. As far as data speeds I haven't had a chance to test them yet. I do this away from my house because I get terrible results in my house.

Battery life really depends on your setup. I have wifi sleep policy set to When screen turns off and background and sync off. I manually sync my programs and email and usually get 40 to 50 hours of light use.
[Captivate Android Development] doreyu:
Currently on JQ1 and it's been performing very nicely.

from a full charge I got about the same amout of battery life compared to JPG with the same usage
[Captivate Android Development] markmunsch:
Using jq1 right now for the first full day, battery life still at 84% after 8 hours, 35 minutes of screen time. Showing 4 full bars on the 850 band, out in South Texas where reception can be spotty. So far liking it.
[Captivate Android Development] Pierce533:
Thanks for the info. I tried JQ1 about an hour ago and it just doesn't pick up signal like JK4 does for me. Other than that the call quality was good (when it picked up strong signal) and it switched bands nicely.
[Captivate Android Development] dmnall:
Actually jq1 is actually picking up signal very similar to jk4 for myself, if you are experiencing issues with jq1 not picking up signal, go into recovery advanced and then clean Dalvik Cache is what worked for my phone. Sounds like it is not switching over to 850 mhz band on your phone. So I would try that before ruling out the whole issue with jq1 not picking up signal. I bet you, your phone is still riding the 1900 mhz band.

HTH,

Charlie
[Captivate Android Development] white00gt:
I tried it and my phone was working on 1900 and had a crappy signal so I had to go back to JK4 , might try clearing delvik cache after installing it again
[Captivate Android Development] shoman94:
I'm back to JPG and for one reason... Data..... JQ1 can't quite handle the data for me. Voice was great as it would hold onto 850 when needed but data wasn't quite there as JPG is when at -105db or less. Although JQ1 is definitely a step up from JVE and JJPD IMO.
[Captivate Android Development] shoman94:
Did you use use process I posted above?
[Captivate Android Development] :
JQ1 seems to be really good signal wise and call quality to me sounds about as loud and clear as KB1. Ill have to do some data tests and see if GPS, battery and wifi are any good with it. Im holding onto a strong 850 WCDMA signal where I wasnt this morning with JK4, so thats a great sign!
[Captivate Android Development] Pierce533:
Thanks but it was on the 850 band and I did clear the Dalvik cache. It is just poor signal in my area and JK4 seems to work better for me. Anyone else's mileage may vary. :)

Edit: I gave the installation another shot and this time I am getting better signal from JQ1 than from my earlier installation, but it is equal to JK4, not better, but still just as good. I don't know what the differences are between the installations I did, but it could be a bit somewhere decided to play ball this time around. Stuff like that occasionally happens, though. If the battery use turns out better I will report here. Otherwise, I will go back to the "tank" which JK4 seems to be.
[Captivate Android Development] Overgloc:
Tried the kb1 on dragon rom and getting reboot and alot of FC. Getting good gps and clear talk when it work. Any idea why it rebooting?
[Captivate Android Development] shoman94:
When you say it was on 850 band... do you mean you had the 850 option only checked? Or in the basic screen (*#0011#) it was actually on 850mhz
[Captivate Android Development] shoman94:
KB1 is not made for that rom. Any ROM using an i90xx based kernel needs a i9000 modem.
[Captivate Android Development] WoodPusher:
How was it battery wise compared to JPG? also to go back to JPG did you have go through the flashing processes again or just went straight back to JPG ?
[Captivate Android Development] shoman94:
Battery was similar. It was so close for me. Yea, just flash JPG over JQ1 and you are set.
[Captivate Android Development] Pierce533:
That it was actually

ON

850 as I said before. I have had a similar problem flashing other modems where a reflash seems to help out with signal. I don't know why, but it happens at times.
[Captivate Android Development] mgfjd:
After trying so many modems and going back to JK4.. there is a new King in town...

1. JPG ( Follow flashing instructions)

2. JK4

3. KNP1

Could you please post the flashing instructions for JPG and JQ1 on the first page to keep the thread clean?

I have not tried JQ1 because JPG performs excellent so not need..
[Captivate Android Development] brendanmurphy:
JQ1 is useless on Telus in Canada. It will only connect to GSM 1900 band. And as Telus only has data on Hspa i can only receive calls.
[Captivate Android Development] eliminat:
I had been using JK4, as JPG just didn't have the signal for me in low signal areas, but after trying JQ1 for a few days I believe a have a new favorite. Very Fast, best signal I've gotten so far (basically par with JK4), and low battery usage. I haven't had a chance to try the GPS yet though.
[Captivate Android Development] shoman94:
Weird.

I've PM'd the OP.... he didn't reply to me about it.

My list:

1.JPG

2.JQ1

3.KP1

4.JL2
[Captivate Android Development] shoman94:
Thats because you didn't flash using my method above.
[Captivate Android Development] grkmaster:
ahh!!! the method that wont disappear!! Maybe putting it our signatures will help more people?
[Captivate Android Development] shoman94:
I was thinking about that..... here goes...
[Captivate Android Development] Ikonomi:
Finally got a chance to test JQ1. Pulled 5+ down on 850 and 3+ down on 1900. That 850 result is by far the fastest I've had in this area, but 1900 is average, and JPG was in fact faster most of the time. Upload on 1900 was absolutely anemic, as well, coming in at 0.3 or so, but I'd like to test it in some other areas before I really decide.

[Captivate Android Development] grkmaster:
Ive done the same linking to your post
[Captivate Android Development] bubba9004:
I got a couple of questions:

1st how do you actually read the gsm status screen, the rscp/ecio part do you want the #'s to be lower or higher.

2nd I followed the steps to use JQ1 and used it for the past 2 days. I just decided to go back to JPG and now its on 1900, but all the setting are still the same with 850 checked. Just curious as to why?
[Captivate Android Development] shoman94:
1st: You want the numbers to be lower.... usually -110db to -105db gives you 1 bar.... -90db or less gives you full signal

2nd: Its ok to be on 850. The phone will switch to 850 when needed.... you'll see it go back and forth. Usually just idle...it will prefer 1900 unless the signal gets poor. Example...My drive to works prefers 1900 but if I'm on the phone during the drive it prefers 850 most of the way. If you went from JQ1 to JPG it should work fine.... it has for me and some others. I can actually go back and forth between JPG and JQ1 if I want.

If you have a low signal area in your house ans you can cup your hands around the phone trying to force it into 850 just to verify it works..... if 850 doesn't work it usually drops to GSM1900....if the latter, then you will have to reflash the procedure.

IMO let the modem do the work and enjoy the better battery life from it.

Hope that helps... good luck.
[Captivate Android Development] zerkai:
I always thought it was better to leave it one one band rather than automatic, cause switching bands automatically would consume more battery?
[Captivate Android Development] shoman94:
I've run it both ways...no matter what band you have it on it is always talking to multiple towers.

Same battery either way.
[Captivate Android Development] lmaoxlong:
Hi, I live in California, bay area. Does anyone know what modem would be best? I've tried a few so far, but it's hard to get a definitive answer. Thanks!
[Captivate Android Development] zerkai:
I followed the procedure for jq1 and confirmed that 850 is working. But when switching to automatic (and before enabling 850 in combi) 0011 says its still on 850.
[Captivate Android Development] OBatRFan:
Never flashed a modem before and I have a question: Do I need to flash modems in order? I'm currently on Precision 3.5 with the KP1 modem and I want to flash JK4. If I do need to flash in order, what might that order be?
[Captivate Android Development] shoman94:
If you are flashing jk4 you can just flash that one. Nothing special needed.
[Captivate Android Development] OBatRFan:
Thank you!
[Captivate Android Development] Pierce533:
Sticky Please?

This thread is immensely helpful. I vote it gets stickied to the top of the forum so it doesn't drop out of sight.
[Captivate Android Development] ThisWasATriumph:
I have a v1006 launch captivate which seems to hate every modem. On i9000 modems like jl3 or jk4 it gets no service all the time and on cognition with KB1, it puts the person on hold or something and you cant hear them if you try to answer a call.

What should I try now? Is there any hope at all, or is this phone just plain defective?
[Captivate Android Development] shoman94:
What is your rom and kernel?
[Captivate Android Development] ThisWasATriumph:
Well right now its stock Cognition 4.1.1.
[Captivate Android Development] thunderteaser:
I'm sorry for my noobiness, but I was wondering: what's the point in having 850 MHz band? Is there some mobile operator which doesn't use SGS default frequencies?
[Captivate Android Development] shoman94:
If you are running the kernel it came with you can only use captivate modems. So your choices are kb1, jj4, ji6
[Captivate Android Development] shoman94:
It depends where you sure located. 850mhz is a frequency used in the USA and Canada. The lower frequency give better in building coverage and travels further from the tower. Which usually leads to better coverage.

Typing and driving.... Not good to do...lol
[Captivate Android Development] NISMOFO:
Huge help!! Seems like Cog really has its limitations on modems. I hate kb1...I might have to drop cognition just because of modem selection.
[Captivate Android Development] shoman94:
I wouldn't blame you myself.
[Captivate Android Development] ThisWasATriumph:
yeah i'm flashing serendipity again so i can try out some of the new i9000 modems.
[Captivate Android Development] eliminat:
I'm still on Cognition 3.04 and firebird kernel myself.
[Captivate Android Development] NISMOFO:
The static I'm experiencing is on the speedmod FAQ page and says its due to using a captivate modem rather than i9000. But I have both an i9000 kernel (speedmod) and an i9000 modem, but I'm on the latest Cognition which is not i9000 based. Confusing why I have the static...it might be one of the downsides to mixing & matching.
[Captivate Android Development] OBatRFan:
...so flash a Captivate kernel and modem? i9000 with i9000 and Captivate with Captivate.
[Captivate Android Development] froli13:
nevermind...
