[Captivate Android Development] :
Hi to All,

My Galaxy S has the 3G 850 Hardware, I have enabled it via the menu as in the first thread but even after I installed the "JVO" modem & after dialing "*#0011#" still shows the UMTS 1900 only, why? I have done everything, am I missing anything?

Thanks a lot for any help
[Captivate Android Development] :
Hi,

I have the UMTS 850 hardware & flashed the "JVO" & everytime I dial the "*#0011#" everywhere I go my phone shows "UMTS 1900", however those areas are 850 dominated. Am I missing anything?

Thanks
[Captivate Android Development] shoman94:
What did you flash from?
[Captivate Android Development] :
I flashed the CWM 3.0 for 2.3 which I have it. All from the first thread.
[Captivate Android Development] shoman94:
No I meant what modem did you flash from.
[Captivate Android Development] :
the "JVO" modem in the first thread flashed it to my 2.3.3 official ROM.
[Captivate Android Development] alexige:
He's asking do you know what modem you were on before flashing JVO.
[Captivate Android Development] shoman94:
lol... What modem were you running before you flashed JVO? If you were running stock JVB/JVH official then it comes with JVK which you probably didn't have 850 to begin with.

SO you need to flash the modems using the method from my signature.

Thanks
[Captivate Android Development] :
Oh, sorry that I didn't understand it!! yes I was on the stock ROM JVK with it's modem. Could you please give me the link to flash "your signature" first? lol.

I'm very grateful to your time & effort.

Thanks
[Captivate Android Development] eliminat:
shoman94,

Are you planning on possibly adding JVO to your spreadsheet, or update your spreadsheet with new tests under GB to see if there's a difference with some of the modems?
[Captivate Android Development] shoman94:
Its the link in my signature that says flash JVK, JPG etc... modem.
[Captivate Android Development] shoman94:
Yea.... I would have to do a new spreadsheet for GB as it seems to me the modems act a bit different.
[Captivate Android Development] Oxicottin:
Has anyone had thier battery drain fast using JVO..... I have been using it for 3 days now and every 2 hours I drop 15% and thats just idle no wifi or gps
[Captivate Android Development] 4-2ndtwin:
I didn't experience that problem, but I did switch back to KC1 because of better signal and data speeds in my area (Arkansas).
[Captivate Android Development] megatronisabeast:
I like the signal and data speed with KC1 but when I am using the phone it drains the battery a bit quicker than JK4. I reset the battery stats and will see if that helps with the battery or not.
[Captivate Android Development] avs420:
I'm in Arkansas too and no matter what modem I try I can't get download speeds above 1Mbps

My uploads are >1Mbps (about 1.2Mbps) but my download speeds on the leaked Froyo were about 3Mbps

What gives???
[Captivate Android Development] mrhaley30705:
When you switched to 850, was it 850 only? GSM or WCDMA?
[Captivate Android Development] avs420:
WCDMA 10char CDMA
[Captivate Android Development] mrhaley30705:
I would recommend reflashing a modem, use shomans guide if you choose one of those modems. I think enabling all band and choosing automatic might help. Its possible its a carrier issue. It also depends on network traffic.
[Captivate Android Development] avs420:
I've tried whatever comes with Continnium

JK4

KC1

Same result. Tried automatic, 850/CDMA, all bands, etc. Cannot get above 1Mbps. Earlier I was hitting almost 3.5Mbps on whatever the Froyo leak was based on
[Captivate Android Development] shoman94:
Today I had an opportunity to play modem jump today. At my work... 500,000 square ft building. Steel shell and concrete inner walls. I found a spot that had a signal strenght of -100db.

I was tryingto use the xda app and it kept timing out... and my phone couldn't connect to the google server. SO I started flopping modems to see of one would work.... I was on xxjvo... went to tubjp9-nothing, went to UGKC1 nothing, went to tdvjp9, went to xxjve-nothing, went to xxjvk-nothing, went to zsjpg... boom on boot... connected to google server and recieved new email... connected xda app and was able to browse with 80% success.

So... just a little insight...Guess I know what modem I'm using.
[Captivate Android Development] mrhaley30705:
Keep trying different modems. Jusgo to page one of this thread, there are a lot if modems there. I've always been partial to JQ1 myself.
[Captivate Android Development] zuN!:
no modem dance? :p
[Captivate Android Development] VFO:
It's funny you mention that shoman, as you may remember we are sort of neighbors and I too have found zsjpg to be the best modem for gingerbread. The battery life has been the best as well. I would say that holding on to a signal has been where is really shows what it can do. The odd thing is when I was on froyo this modem wasn't a shining star but now that I am on gingerbread it outshines all others.
[Captivate Android Development] TonyStark R.I.P.:
Lost signal?!?

I've flashed a gb rom that has been rock solid in all respects except signal. I flashed dvjp9 which was my best while using 2.2 rom. Having done this, I now cannot send or receive ANYthing. I thought maybe it was my sim so I switched it out...no. This all has taken place in the last three days. Interestingly I do receive text msg at times (once in a great while). On boot up it always says no signal, however signal strength shows 95dbm (mobile signal widget, but says no network) nor do I have ability to use wifi.

Need help please.

EDIT: flashed I9000XXJVK back and it works again. So why am I having issues w/modem_cwm3_xxjq1
[Captivate Android Development] cisco150:
Like to know what modem's better.I have the continuum v5.4.1.I'm in the usa Pennsylvania,with at&t-straight talk,i'm using modem i9000ugjl2.Thanks again for the help,this for gives me.
[Captivate Android Development] :
You didnt try JQ1? :(
[Captivate Android Development] cole26:
In and around the Vancouver area, I find JQ1 has given me the best signal, battery life and speed. I consistently get almost 4mbps down, 1 up. I double the speed of my friends Nexus S. I haven't tried JP9 or JVO though.
[Captivate Android Development] Felixpau86:
Went from dvjp9 to jvo... Been on this for a while. Maybe a week and a bit. Reception is great, battery seems ok but I'm not 100% sure due to gb battery drain issues.
[Captivate Android Development] askpcguy:
Just a random question, is the captivate going to see any of the newer modems make it to CM7 and/or miui?

Sent from the miui matrix SGH-i897
[Captivate Android Development] alexige:
Ask those in the respective threads to make them cm7/miui compatible. You may be able to flash the cwm3 versions but im not sure.
[Captivate Android Development] zuN!:
Sweet thanks for the input. I'll try to give JQ1 a shot if I can find an area that only has 850MHz (an area with -100 or more negative dBm? Someone correct me) for a modem dance on CM7.

Do post your results with the 2 modems you haven't tried yet if you do end up using them
[Captivate Android Development] MaxRabbit:
Does flashing a new kernel overwrite the modem? I was certain that I put on zsjpg but it's now saying I'm running JVK.
[Captivate Android Development] shoman94:
Sorry... That would be a no.
[Captivate Android Development] :
You didnt even try JQ1? :(
[Captivate Android Development] shoman94:
That's the second time you write that. No I didn't. It wasn't in my sd card.

New Modem

New Modem out from I9000 JV9 GB. Shows as BUJV3 (I9000 modem). For those that care, JV9 is a Vodafone ROM.

http://xdaforums.com/attachment.php?attachmentid=600894&d=1305802070

I tested already and it doesn't even come close to KC1 where I live. May be beneficial to others though.

Flash with CWM3.
[Captivate Android Development] ccdoggy:
I went to an area I usually get 3G/H connectivity but it refused to change to either, staying on Edge.

This is with JVK installed with the 850 trick on Mosaic III just flashed yesterday.

Anyone else seeing a similar problem to this? I am pretty sure I have not changed anything else other then adding the modem doing the 850 dance.
[Captivate Android Development] shoman94:
I didn't post it because I tried all kinds of combinations and could not get 850 enabled. JV3= Fail if you need 850MHZ
[Captivate Android Development] LNJ:
JVO doesn't work on 850 anymore since C5.5

Probably needs the dance.

[Captivate Android Development] TheShamsMan:
Hey guys!

Can someone tell me what I do when I *#2263* and change the band to 850 and it doesn't stay changed? It always reverts back to 1900.
[Captivate Android Development] F1reEng1neRed:
Did you do the dance?
[Captivate Android Development] F1reEng1neRed:
I had it on mine, but I could tell right away that it wasn't for me. Signal strength was terrible and phone was constantly jumping from band to band and having no signal in areas where I would usually get at least 2 bars with most other modems.
[Captivate Android Development] goabunny:
Sorry for asking this question but what exactly mean by 'dance' here?
[Captivate Android Development] TheShamsMan:
Definitely did the dance. Follow the instructions to the letter.

Used the dialer and SGS Tools. Neither worked. I'm on JQ1 now and it's pretty terrible here in Montreal.
[Captivate Android Development] F1reEng1neRed:
Looks in the OP or the sig of shoman94.
[Captivate Android Development] F1reEng1neRed:
So you did *#2263# and went to WCDMA bands and selected 850 only. After that you hit the menu button and selected end. You went back in and it was back to 1900? Was this with a different modem or JQ1?
[Captivate Android Development] TheShamsMan:
Correct. I just flashed JP9 and it was the same.

When I clicked 850, it'll say something like menu doesn't exist. Still experiencing the issue.
[Captivate Android Development] shoman94:
You need to start back over. I'm not sure exactly what you are trying to do. If you are trying to flash JQ1 then you need to do the modem dance in my sig. If you do that it will work fine. I see you said you followed to in detail but you having issues so I'm not sure about that. Try to be a bit more detailed in typing what you're doing so maybe I or someone may help you out.
[Captivate Android Development] Nuskul:
Any feedback on tdvjp9 battery life? Just installed and speeds are best yet (3k down and 1.8 up ) and GPS locks faster than ever 3s .

[Captivate Android Development] sfernandez:
I like what you are thinking..I would like to take it 1 step further..and if and when the tests can be done...is it at all possible to recompile a kernel with the best of all tests so we can have 1 super modem?
[Captivate Android Development] aaron8301:
MMS over EDGE

Do any of these modems fix the MMS over EDGE problem? Very rarely can I send a MMS on EDGE. And contrary to what AT&T would like you to believe, their 3G network doesn't cover "97% of all Americans," especially in many parts of Oregon where I travel every week for work (I live near Seattle).

I've researched this problem and it appears to be a Captivate thing. I'm just curious if any particular modem helps.
[Captivate Android Development] mrhaley30705:
What rom are you on, and what modem are you using?
[Captivate Android Development] shoman94:
The network does.... not the 3G network.

Not sure what could be the problem. It works fine in 3G?
[Captivate Android Development] TheShamsMan:
I'm simply trying to follow the "dance" as per instructions in the OP, but every time it'll revert back to 1900. I'm not going to complicate this by giving more details. I"m on a GB ROM and all I want to do is flash a different Modem as per OP, but for some reason, the 850 settings just won't "stick". I followed the instructions to the letter and have even enlisted help from other thread. Still not working. I've tried 3 different Modems, but always started with JK4 then JPQ then JQ1/JP9.
[Captivate Android Development] stuff:
I am running KC1, although on CM7, and running a speedtest gives me a whopping 3548 kbps download, 1277 upload.

Pretty awesome if you ask me.
[Captivate Android Development] :
We need a new up-to-date poll, or perhaps a separate poll for GB modems/roms (since they seem to act a little different than Froyo).
[Captivate Android Development] :
Hmm, I wonder if the Infuse 4G modems would be compatible with out Captivates and be able to access the "4G" side of the network? Anybody have any theorys on that?
[Captivate Android Development] eliminat:
As far as I've seen the Infuse and the Captivate have different radio chips, so if that's really the case, no.
[Captivate Android Development] :
I thought the only difference was that our captivates are only able to do HSPA 7.2 and the Infuse can do 14.4?
[Captivate Android Development] alexige:
You should do jjpg after jk4. I think that's where your problem lies.
[Captivate Android Development] eliminat:
Captivate chip can do 14.4 Mbps (HSPA) but is limited to 7.2 Mbps -

Infineon PMB 5703 - http://www.infineon.com/dgdl/SMARTi...00e17&fileId=db3a304317a748360117c036cad341b1

Infuse 4g chip can go up to 21 Mbps (HSPA+)
[Captivate Android Development] :
So then since all hardware is the same (save from the speed limitation) then we should be alble to use the Infuse's radios and get higher dl/up speeds, right?
[Captivate Android Development] alexige:
But I think you will need a kernel built off the infuse which probably also requires a rom. Would be a cool idea if that's what it takes to get hspa+ working on our phone.
[Captivate Android Development] eliminat:
Those are 2 different chips, and thus, most likely 2 different drivers, which are normally NOT compatible with each other. So using the Infuse driver on the Captivate would result on the Captivate getting NO SERVICE.

If the company that made the chip made a driver compatible with both, it may provide a small difference, but unlikely to be the kind of boost you're hoping. To get that would be more the networks upgrading their equipment.
[Captivate Android Development] garringm:
Why dont you try it and let us know someones gonna do it so it might as well be you
[Captivate Android Development] :
I thought the hardware between the two phones were the exact same... just a bump in screen size?
[Captivate Android Development] TheShamsMan:
Alright. I'll give that a whirl. Will report back.
[Captivate Android Development] mrhaley30705:
DVJJPD &DVJJPG are both"bridge"modems. I had better luck with jpd than jpg. If one doesn't work, try the other.
[Captivate Android Development] shoman94:
lol and you said you followed the instructions to the letter.... :rolleyes:
[Captivate Android Development] topiratiko:
just an fyi...getting INSANE data speeds on jvo modem... 4.45 mbps down 1.25 up
[Captivate Android Development] aaron8301:
I'm running Serendipity 6.4. I WAS using whatever modem came with it at the time of my posting, but have since switched to TUBJP9. It seems to be working OK now, whereas before I could NOT send a pic message over EDGE (everything worked fine in 3G). And although this modem gives me much lower 3G speeds, it's given me a much more reliable EDGE connection in general (data, voice & mms), so I'm gonna stick with it and consider this an answer to my question.

I don't think it's rom specific; a little Googling shows it's an inherent problem with all Captivates, both those that are rooted-customized and those that are bone stock.
[Captivate Android Development] melvinaury:
I'm running Serendipity 6.4. I live in Puerto Rico I already test all the modem and for me the JVK was the best and in second KC1 and JP9. With JVK my GPS locks in 5 seconds and in maps I have a 5 meter lock.

I don't know how to attached the test results, but in Speedtest in Carolina Puerto Rico today at 1:38 pm my test was Down 5.27 Mbps , Upload 1.27 Mbps and Ping 262 ms.

Thanks to all, for all the excellent info.
[Captivate Android Development] $omator:
i dubt that modem have impact on gps accuracy as that is even separate chip.

had some moded gps files while flashing diff modems jve/jvo and saw no change in gps performance - files were intact.
[Captivate Android Development] emuneee:
GPS calculations are done in the baseband. Modem files can have a significant effect on GPS performance.
[Captivate Android Development] H3llstorm:
Agreed. I get significantly better GPS accuracy with JVO than with any other modem - and a GB ROM.

When I was using Froyo, JVK was the modem of choice.
[Captivate Android Development] beaver2233:
I have one question, I have flashed multiple modems myself through cwm without a problem. A friend of mine isn't happy with his signal and I recommended changing modems however he doesn't have (or want to have) custom cwm...is it possible to extract the modem file from the .zip and flash via Odin, if so which file ? And if not, where could I download Odin flashable modems ?

Cheers, appreciate your time
[Captivate Android Development] :
Hi,

I'm currently using the 850 UMTS enable modem so my question is if I installed another ROM should I avoid installing the modem in order to keep the "850" enabled or it will always stay no matter what I install in the future?

Thanks for any answer
[Captivate Android Development] $omator:
basicly

i guess modem.bin contain 'firmware'/patches for BCM4751 and as well for the BCM4329

but like said i have not seen any noticable difference betwen some

froyo modem i used 'back then' and gb ones

much more changed while i experimented with hmm deamons and libs that 'run this circus' ...

Anyone try the KE4 modem from the SGSII yet? http://xdaforums.com/showpost.php?p=14011308&postcount=150
[Captivate Android Development] justmart:
I think you can not use other phone modems... like u can not use vibrant modems on captivate. We use i9000 modem because we have i9000 kernels.
[Captivate Android Development] :
Oh, I thought we could with the latest GB rom builds off of the SGSII. Oh well...
[Captivate Android Development] alexige:
This sounds like your friend is stock. He's not going to be able to use other modems like the ones in the OP of this thread unless he runs a reoriented i9000 kernel (such as onix for froyo or talon for gb). And he can only use reoriented i9000 kernels if using a custom rom.
[Captivate Android Development] justmart:
Those roms are not builds of sgs2. They are i9000 builds... But with things of sgs2... Like widgets apps etc.

[Captivate Android Development] Nismo88:
i want to try flashing a couple different modems, im running GR-12, which is gingerbread, however it still has the CWM2. so im wondering do i still choose the CWM3 file? also which modems would you recommend trying in canada, iv read JL2, and KC1. thanks
[Captivate Android Development] alexige:
If its CWM2 your going to want to use CWM2 modems gingerbread has nothing to do with it its the recovery you have to consider in regards to your location i do not know.
[Captivate Android Development] eliminat:
If you still have CWM2 something went wrong. GR-12 comes with a kernel that has CWM3.
[Captivate Android Development] Nismo88:
hmm, when i go into recovery says CWM v2.5.1.2

definitely on gr-12, with the latest 1.2 reoriented xcal kernal. should i be trying to get CWM3 on there?
[Captivate Android Development] Holmes108:
I can't comment on the kernel that comes with GR, but I know Xcal's latest posted kernel is CWM2, because he just mentioned CWM3 will be in the next release shortly.

If the person above is correct, it's possible Xcal included a newer version of the kernel with the Rom. (for example, Continuum often has a version of Talons kernel that hasn't been released in the kernel thread yet).

Did you (re)flash the kernel after the flashing the Rom?
[Captivate Android Development] tjsooley:
do any of the sgs i9000 gingerbred modems have 850?

I am on cm7 and would like to test with newer modems.
[Captivate Android Development] eliminat:
Re-reading the thread I may actually be wrong. I thought it came with CWM3, but since I've changed kernels since then I can't check.
[Captivate Android Development] nkrick:
You mention two Broadcom chips; the 4751 is a GPS chip and the 4329 is a 802.11b/g/n + Bluetooth and TM radio chip. Neither of these chips is the modem used for Cellular signals and what I have read indicates that they have nothing to do with the modem.bin. There are constantly some people saying that the modem affects GPS, and other people saying it has no impact. I'd love to see hard evidence that the modem controls GPS, or WiFi, or anything else because it would help settle this matter.
[Captivate Android Development] tjsooley:
Just my 2 cents.

I have use the same rom with 2 modems jl3 and kc1 and do see a difference in gps fuction on both. I have a batch 1 1007 captivate that has not been on a i897 modem from the day froyo source came out.
[Captivate Android Development] $omator:
hehe yea was a bit wasted, its YYN1N7438A8 with PMB 5703 SMARTi UE

modem.bin is a package that contains fw/updates for chipsets that we got,

that includes baseband as well as wifi, gps and others that can be flashed/updated

other thing that matters are drivers/deamons - lets call it 'software' that 'run that circuss' ;]

both fw and 'software' have impact on overall performance.

some modems are targeted for specific countries for example,

sometimes chip fw needs a patch or simply there is new fw version developed.

latest drivers on the other hand are here to deliver latest fixes, tweaks and compatibility fixes

one thing i can say bout modem and wifi is that JVE have better wifi than JVO and i see no difference on GPS performance here

but i can change GPS performance mixing 'software' from other fw releases or phone models even ;]

like atm i am using nexuss gps files =)
