wow..... jpg is rockin... i did try and flash directly over jk4 because i'm in oz and there is no 1900... but nay

after jpd every thing was effortless. for me no need to change band selection it's happy staying on 850 in auto.......jq1 is lined uo to try in the next few days.

this is a strange method indeed but it works. instantly better signal and consistant data speeds.

thanks shoman94 for this amazing discovery!
[Captivate Android Development] shoman94:
Yea I didn't have to either but it didn't work that way for everyone that tried it....setting to 850 during flashing is failsafe.

Glad you like it.... I know I do.
[Captivate Android Development] devz3r0:
My apologies for being away for a few days and not being able to check my pms guys. Great work on the progress, especially shoman94!!

When time allows, I will add the direct link to your very helpful method in the OP so it doesn't get lost.

If there is a demand I can pack the current modems in the way CM7 reads them for an install.

Let me know...

P.S. Still looking for a mod / admin to remove the poll and sticky the thread. If anyone can help it's appreciated.
[Captivate Android Development] JJ133169:
what standby drain are you guys getting per hour with UGJL2 ??? seems in 3 hours of No use I went from 71% to 60... I'm doing more testing, maybe that was a bad service area ( my gfs house isnt the best for service) but what should i expect to see?

New modem

New modem here (Not really new). I leave you BVJJPG, appears to be a succesor of BVJJPD. Shipped with a 2.2.1 firmware and has the 850 mhz goodness by default. Any takers?
[Captivate Android Development] shoman94:
Shipped with which rom?

[Captivate Android Development] shoman94:
Sorry... I looked at packed by mistake. It's definitely a different modem....
[Captivate Android Development] brisknfade:
I've gotten amazing speed on JS1 with 1900mhz. 4.95 down and 1.30 up. 850mhz tipped out at 3.2 down and 1.3 up. Promising indeed.

cool new jpg...... keep us posted

+1 STICKY for sure.......
[Captivate Android Development] {Angel}:
No problem. I´ve been using it for a few days without problems. I´m looking forward to your rigorous testing. Please keep us posted. Nice to know its performing admirably for now!

Really? That sucks... I havent experienced that though. Havent noted any distracting with voice. I have been getting very good data and battery life. Im going to hang on to it a bit more to give it a chance. Ill pay more attention to the voice quality. I suppse other factors weigh in, like your location and carrier. Thanks for your feedback!

How do you feel about JQ1 vs JS1?

Hey.

Wow getting pretty confused with all those modems :D

I Live in western Germany and im searching the best modem for me. -Battery life and performance/signal strength/call quality/etc.

At the moment im using JVE and im pretty happy with it. But i would still like to know whether there is a better one out there ;) I did flash ZSJPG once but when calling, people couldn't here me?! I flashed XXJVE and everything was fine! What about that JP5 -can't find a link...

Thanks in advance!
[Captivate Android Development] geokilla:
How's the battery drain on JQ1 for you guys? I'm currently testing it and I'm on my 2nd charge. According to the battery use page, my phone's been unplugged by over 3 hours and cell standby used 38% of my phone's battery. Phone idle used 19%. Currently sitting at 85% >.<
[Captivate Android Development] shoman94:
Well.... Look at your usage stats by either going into SGStools and go into secret codes and select usage stats and device info. It will give you more battery information or in the dialer: *#*#4636#*#*

Did it only happen after flashing the modem?

What modem did you use prior to?
[Captivate Android Development] shoman94:
I answered you in the other modem thread.
[Captivate Android Development] harpo1:
Is it normal for the dialer to use most of the battery? No phone calls or texting? Just checking SGStools and settings a few times.
[Captivate Android Development] shoman94:
Yea... I never understood that... but if you click on it... there are a few apps that are attached to the dialer.... it does get better though... the more cycles you charge your phone the better... I've seen. My dialer though is using very little on Continuum v4.... Android system is the highest under sensor usage
[Captivate Android Development] shoman94:
Sorry... I don't have the odin version..... cwm so much easier
[Captivate Android Development] shoman94:
I tested both some today.... Sound quality wise...JS1 seamed to handle background noise a bit better and data been a little faster for me. JS1 IMO switches to 850 more.
[Captivate Android Development] {Angel}:
Just extract the modem.bin from the zip ans flash with odin.
[Captivate Android Development] jamesbchrist:
The serendipity 6.2 Rom comes with JK4, do I still need to start at JL2 to get to JQ1?
[Captivate Android Development] geokilla:
Running is 100% since last unplugged, which is 5 hours ago. Same with Dialer. So something is stopping the phone from sleeping it looks like. Could it be the modem? I'm at 73% now with 20% drainage from cell standby, 10% from phone idle, and 4% on voice calls. It could be that the battery isn't calibrated yet as I'm currently on my 2nd charge.

Btw, all this talk about JS1 being better than JQ1 and JK4 makes me want to test it out. However I can't seem to find the link for it.
[Captivate Android Development] harpo1:
Here you go.

View attachment modem_bujs1.zip
[Captivate Android Development] shoman94:
Yes you can start from JK4 just follow my instructions in my sig.

100% running means your phone isn't sleeping. Not a modem issue.

Look at the sensor and partial awake and cpu etc... look for the culprit... most of the time its there.

Also to make these modems work properly you need to flash per my sig. I assume you did?

JS1 is a great modem.... link is on the first post of this thread.
[Captivate Android Development] shoman94:
You make it to easy....lol
[Captivate Android Development] geokilla:
Sensor, CPU, and GPS usage is relatively normal as the bars are less than I'd say 5 to 10% full. The dialer is full in network usage and partial wake. That's what I meant in my last post by "same with Dialer". Maybe I'll just upgrade to FireFly 2.7 and see if that changes anything. Everything was fine before anyways.

Yes sir I flashed from JK4 to JPD to JQ1 as per your sig. I'm going to flash straight from JQ1 to JS1 for now. Doesn't hurt anyways, except for maybe 5 minutes of my life wasted.

Oh I'm blind.... I didn't see it in the OP lol. So all these JXX modems are from 2010 right? Since KXX modems are the 2011.
[Captivate Android Development] shoman94:
Well... not all... Some Jxx's are 2011

When you click on dialer what does it say? Any apps?
[Captivate Android Development] harpo1:
You did it for me a few days ago so I figured I'd pass it on to someone else.
[Captivate Android Development] shoman94:
lol... yea... I'm nice sometimes.:p
[Captivate Android Development] geokilla:
That's pretty stupid... The naming scheme that is. Cus I swear KXX means 2011.

When I click on Dialer, it just says Partial Wakelock: Dialer. No mention of apps anywhere.

And I didn't know that you can click on the dialer either. I just learned something new! :P

Edit: Just flashed to JS1 from JQ1. Still have WCDMA850 =)

[Captivate Android Development] garringm:
I live right smack dab in between both of you outside of Wash. CH and JL2 seems to work best for me, JQ1 acts like it has problems holding on to the network, seems to work real well when I get to London but JL2 seems to be a decent compromise, Have you tried JS1, wondering how it works?
[Captivate Android Development] .:Crack:.:
Sorry for crossposting again.... won't happen again!

thank you, still got a few questions

1. Whats better with JPG than JVE?

2. Whats better -JPG or BVJJPG? -Or whats the difference?

3. Isn't using a "ZS" (Asia) modem bad for signal strength in Europe?

4. what about JS1`?

Thanks again!

Edit\\ I live in a pretty low signal area. My carrier is E-Plus/Medion Mobile.
[Captivate Android Development] garringm:
Easy answer start flashing until you find one that works best in your area and on your hardware, if your gonna flash these modems you mention specifically then you should follow shomans flashing modems guide its attached to his signature I think.
[Captivate Android Development] {Angel}:
Does JS1 have 850 by default or does it require the flashing trick?

Can anybody comment on battery?
[Captivate Android Development] dingokevin:
You need to do the flash trick.
[Captivate Android Development] IStern:
San Francisco bay area...went through the flashing trick and ran with JQ1 for a bit, good battery life and speed test results, but unable to place phone calls.
[Captivate Android Development] shoman94:
Weird... I would try again. Are you running an i9000 kernel?
[Captivate Android Development] garringm:
I seem to be having some problems with this js1 modem, I flash it following shoman guide and automatically i get put in airplane mode, any ideas
[Captivate Android Development] .:Crack:.:
Thanks but i have one thing to mention to "1."

My question was, why JPG better is than JVE (Ginger). Like in whihch points.

And do you like JS1 more than JPG? Had the feeling, that i have a bad signal strength with JS1 -is that right?

Thanks! you and garringm are really helping me!
[Captivate Android Development] chase10784:
I am confused. I am trying to flash js1 to my phone to give it a little test run and every time i do the little trick to flash it i go from jk4 to jpd, to js1 and i have no service at all. However i can flash to JQ1 and it works just fine on the 850 band....so i mean what could i be doing wrong?
[Captivate Android Development] grkmaster:
JS1 gives me a nice X with no service! JQ1 works fine but when I flashed JS1 once before JQ1 and after, i still get no service.. how is that possible? I have full service with 1900 and 850 here at my house
[Captivate Android Development] chase10784:
sounds like your in my boat.
[Captivate Android Development] grkmaster:
Maybe there's another trick? lol but for now till we find out why JQ1 will do justice as I had luck in the past with it
[Captivate Android Development] garringm:
If there is another trick i havrnt foynd it yet
[Captivate Android Development] geokilla:
Has anyone experienced a problem where their Captivate has signal, but the network can't be used? It happened to me twice today, at two different locations. As usual, it happened to me at school where it showed I had 2 bars and a 3G connection. However when I tried to send a SMS, make a call, or browse the web, nothing worked. Everyone else around me is fine though, and same with my old Sony Ericsson so it is definitely a modem/phone problem. I already switched the SIM out for a new one too. I even got a reconditioned Captivate from Rogers to test it out, but still got the same problem.

The 2nd time it happened to me today was just outside of the subway station. Keyword is outside. I wasn't underground. I had full bars, but again I couldn't use the network.
[Captivate Android Development] eliminat:
I had that happen to me when I tried the KP1 modem. Haven't had the problem with any other modem I've tried though.
[Captivate Android Development] garringm:
Happens to me all the time Im still trying to figure out the js1 going stright into airplane mode
[Captivate Android Development] :
Im in Southern Cali and JQ1 is by far the best modem Ive ever used. JK4 was my best modem, but JQ1 blows it out of the water. Ive now been running it over a week, still fantastic performance across the board.
[Captivate Android Development] geokilla:
It's happened to me for every single modem I've tried. This includes stock Rogers modem, UGJL2, UGJK4, and atm JS1. The more I test it the more I think it's a phone problem and not network problem.

Both the reconditioned and my own Captivate are manufactured in 1010, which I guess October 2010.
[Captivate Android Development] AReynante:
Inland Empire, or So Cal, I'm doing alright on JQ1. My dl/ul speeds were better on JL3, but jk4 and jq1 are about equal for me. Idk what it is, because everyone else is raving about it.

Also, I can go from jq1 to jk4 or jl3 without the trick right? its only for going to jq1?
[Captivate Android Development] askpcguy:
Not true. You can flash a i9000 kernel along with a i9000 modem.

Note: Bluetooth heatset will produce static. Use a wired headset if desired.
[Captivate Android Development] askpcguy:
Is jq1 an i9000 based modem?
[Captivate Android Development] {Angel}:
Yeah it is.
[Captivate Android Development] shoman94:
JPG has better data service at minimal service areas... also faster data speeds.

So far I like JS1 a little better. My recent test with a JS8 based rom, JS1 gives me just a little better sounds quality. Signal strength is the same with either.

No trick
[Captivate Android Development] garringm:
JVE at least for me had problems staying locked onto the network, when it did it would hang on to the weaker signal and wouldn't handover until it dropped signal altogether, jpg works decent when I am out in the open in stronger signal areas, not in my house or work, since obviously these are the 2 places I frequent the most I must tailor my phone to suit, with this in mind I am running the jl2 modem this seems to be the best compromise between both, I am still doing extensive testing with modems trying to find one that gives me decent call quality as well as a good data connection in my house this is where I use my cappy the most. I am starting to suspect that the rom or kernel is my problem with the JS1 modem.

For those of you that are running the JS1 modem what ROM and KERNEL combo are you running, here is mine

ROM--> CONTINUUM V4 THEMED (JS8)

KERNEL--> LATEST ONIX I AM NOT RUNNING ANY OC OR UV

I have downloaded the file several times ruling out a bad download I have even dropped it into the ROM zip and flashed the entire rom ?? still no go
[Captivate Android Development] rajendra82:
I am having a weird issue here. I tried to use the UGJL2 modem that everyone seems to like per the (now outdated) poll, but when I flashed it, I could not get the downloads to be any faster that the AT&T crippled non HSUPA speed of 300 kbps. When I flashed over TLJL3 instead, and stood in the same spot to run the test I got HSUPA (granted it was only about a 2 bar signal, about the best I can do near my house in the Atlanta northern burbs).

Has anyone seen this before? What would cause HSUPA to be disabled with UGJL2, but enabled with TLJL3? I have a build 1007, i897, and am running the Onix 2.0.2 kernel, on a rooted and debloated stock KB1 ROM and framework.

What are the disadvantages of TLJL3, and what is the current consensus on the modems (if one exists). I tried XXJVE for a short while, but found the signal strength very low, saw a fluctuating Roaming issue after dialing *#0011#, and could never really get the phone to flip over to 850 MHz, or force that band in any way. On a KB1 based eXistZ kernel and KB1 modem, most times I seem to be on 850 MHz band with an occasional switch over to 1900 MHz, and never have any signal issues. Since I am trying to play with an i9000 kernel, I would like to find an equally reliable, but HSUPA capable modem.
[Captivate Android Development] garringm:
try reverting back to jk4 modem as a base before flashing others, this seems to be an overall universal modem for everyone, this should enable the hsupa feature dial *#2263# check in your combi bands make sure that wcdma 850 is starred, then check to make sure you are actually utilizing the 850 band with 0011. after all that try reflashing ugjl2 modem again.

The JQ1 modem is pretty good for low signal areas with good data connection at low signal as well, you may try this, if you feel like trying this one youll have to follow shomans guide I believe is now on the first post.

I have my wifes phone on the jl3 modem it seems to be doing alright for her, I used it for awhile, I think its comparable to ugjl2 modem
[Captivate Android Development] rajendra82:
OK thanks. I'll try XXJQ1. What about BUJS1? Does that require the serial flashing procedure too? Some people here seem to like it as well as XXJQ1.
[Captivate Android Development] goodolsen:
I tried the JS1, but it wasn't nearly as effective for me as JQ1 which I'm currently using. I also happen to be one of the lucky ones who has H coverage where I live.
[Captivate Android Development] rajendra82:
Does JQ1 switch to 850 the first chance it can like JS3, or park on 1900 as long as it can like everything else I've tried so far? This seems to be the key to my success with TLJL3. Here in Atlanta, the signal quality and speed seem far more robust on the 850 band than on 1900.

I tried JS1, and it could not even download a 7 second long voice mail I left myself for a call quality check. On the other hand JL3 got it down instantaneously.
[Captivate Android Development] grkmaster:
How did you get JS1 to work for you. Just like you, if im not mistaken, on Continuum v4 themed with onix and you have no problem with JS1 while i cant connect. I dont understand why
[Captivate Android Development] LNJ:
I like the BVJJPG. Seems to default to 850 and works as good as the JL2.

Only the ZSJPG is listed on the first page but if you guys wanna try out the BVJJPG, you can get it from this post: http://xdaforums.com/showpost.php?p=12156313&postcount=438

I have read the thread and successfully gone from JL3 using shoman94`s process. Worked well except for a major/minor glitch. I have no idea how I did this but I changed the [5] wcdma band 5 to a [6], then of course had no service what so ever....figured out that using the key input button got it back to the right number. In searching/playing I must of changed it by accident...lol a few tense moments...

I will report my thoughts on JS1 testing and then I will also test JQ1. Thanks guys all the posts have been a great tutorial on how to do it right!!! Except for my curiosity/stupidity!!!
[Captivate Android Development] olo567:
I used the serial flashing procedure to get JQ1 working, but like you I get no signal connection with JS1 even following the same procedure or flashing from JQ1. No clue why.
[Captivate Android Development] H3llstorm:
I've found that JS1 works best for me if I keep it on 850 rather than automatic.
[Captivate Android Development] shoman94:
Funny you mention that. It happened to me once. So I went from jl2-jjpd-jpg-jq1. Enable 850 in jl2 first. Try that let me know.

Edit: do not flash with the usb or charger plugged in.
[Captivate Android Development] zerkai:
I can't get js1 to work either,no matter what I do. Oh well.

I'm trying out bvjjpg. Impressions for signal: good. Best I could get with any modem in my room is 2 bars with a rare jump to 3. With this, I get a consistent 3 and a rare jump to 4.

Not that I could notice the difference voice call / texting wise though lol :-P (between 2-3 bars) but its nice seeing my signal status light up 3/4 most the time :-)

The only time I see this is if I use gsm850, but according to *#0011# its wcdma850 ;-)

[Captivate Android Development] zerkai:
Well, not all in one go... what I mean is that I went from jl2 (enabled 850), then jpd, then jpg. Then days later I went straight to jq1, then days later today I tried js1 and failed so went to bvjjpg.

But I have already tried jl2 jpd js1 and jl2 jpd jpg js1. I don't understand why it has to be so troublesome lol

[Captivate Android Development] olo567:
Just tries the sequence you suggested, service on wcdma 850 up until js1 again. Then nothing. Flashed straight to jq1 from there and good signal again. Guess I'll just stick with that.
[Captivate Android Development] shoman94:
Because they are not made for our phones. I'm not sure why its not working for you.... They all work fine for me and many others.... I don't know if it is ROM related either as I have flashed 10 different ROMS and they all worked fine.
