Rogers?

I'm running my cappy on Rogers with CM7, I noticed that I never get HSDPA like I used to on stock. None of the codes provided in the OP worked so I have no idea if it's the modem or the rom causing this. I'm using the T595TLJL3 modem if that means anything. I'm under the impression that Rogers is supposed to operate on the 850mhz band, though coming from the Nexus One, all this is a little overwhelming.

Thanks!
[Captivate Android Development] shoman94:
hmmm. I would try running a modem that is made for GB like JVE or JVK. I have to experience with CM7 so I have no idea. What are people running in the CM7 thread? I thought I saw mention of that issue in there.
[Captivate Android Development] {Angel}:
Why did you decide to go back to JQ1? Its likely that if you wanted to go back that flashing one of the BVJ modems and following the flashing sequence should work.

Im currently testing out another new 850 modem and yet to test KC1 since I like to give modems a fair chance. But I will switched to KC1 soon enough. I am really trying to find a good native 850 modem, those european and asian modems while they work have some odd behaviour at times and the fact they are not made for our 850 modems kinda leaves a bad taste in my mouth, but I'm weird like that ... :)
[Captivate Android Development] shoman94:
Which one are you trying?
[Captivate Android Development] SweetwaterBurns:
Try running a speedtest to see if you're getting HSDPA speeds. A lot of times it will say UMTS or 3g but you'll actually be on the higher speed network.
[Captivate Android Development] autoreiv:
I have anywhere between .8 -1.8mbs download and 1 - 1.4mbs upload. Normally my speeds are a -little- faster. In any case it's not that big of a deal. I just want to make sure my actual coverage doesn't suffer.
[Captivate Android Development] perosredo:
Which build this is UGKC1 modem come from? I can see that it's an 'Aries' labeled modem from the hex but can't see the other information that is usually present--including anything identifying it as 'UGKC1'.

EDIT: So it apparently came from a Bell KC1 build and the modem is listed such in Settings/About.

EDIT2: Didn't have to do the JPD workaround to keep the 850 band when I jumped from JK4.

EDIT3: I'm getting 10m GPS accurracy with 6 satellites as opposed to only getting 30m on 11 on any other modem; perhaps this is also more battery efficient. There doesn't seem to be any data performance difference.
[Captivate Android Development] SweetwaterBurns:
I don't know what Rogers 3g is rated for, but on at&t I usually get around .7 down and .3 up on 3g. Your numbers seem closer to what I've been getting on HSDPA lately.
[Captivate Android Development] {Angel}:
I'm trying UBJP9
[Captivate Android Development] caanda45:
Other than this site where is everyone getting these new modems to test? Enlighten me please!!!!LOL
[Captivate Android Development] shoman94:
Yes because this is a native 850 modem.

I will be testing between tonight and tomorrow to see if it better than JVK for me.

i9000 forum list modems at times but mostly I get them for samfirmware.com and extract them from the firmware.
[Captivate Android Development] shoman94:
Is this one 850 enabled by default.
[Captivate Android Development] LNJ:
Can someone post the UBJP9 modem so I can test?
[Captivate Android Development] someonemx:
i'm recentrly trying UGKC1 to see how it behaves.

nice to hear another new modem with default 850 Mhz, so no trick was needed to flash it, the CWM file flash was fine.

with a couple of hours of usage battery seems fine, less than 3% per hour at idle with HSPDA enabled (watching juice plotter) and one MSN & one gmail push account enabled.
[Captivate Android Development] H3llstorm:
Are these "modems" we're downloading/testing more like (from a Windows perspective) modem drivers, modem firmwares or something else entirely? :confused:
[Captivate Android Development] LNJ:
I have no idea why it's called modem.

I have always known these as radios ever since the Windows Mobile days.
[Captivate Android Development] shoman94:
Well.... they are called modems because that what samsung calls them...lol I would agree because they are you to transmit data mainly. You can also call them radios since they broadcast by radio frequency...lol

I like modem myself.
[Captivate Android Development] H3llstorm:
I'm not overly fussed with what they're called, I'm just curious if they're drivers Android uses to communicate with the modems/radios/whatever in our phones, and how they "tune themselves", since some people say that reception can improve over time.
[Captivate Android Development] Chillyw:
I'm using Continuum v4. My fiancee is using Cognition 4.1. She was saying that the sirius xm app was cutting out on her, and that when she was using stock eclair it worked fine.

So I installed it on mine, and sure enough, the data connection would die after about 5 minutes of streaming.

Tried multiple versions of the app (including known good), so figured it had to be the modem. Flashed all of the new modems, all had the same behavior. Out of desperation, flashed JK3, and it worked perfectly. Streamed for an hour without dropping.

I wonder if modems JK4-newer have some problems with tower changes while data is going on. I know in my house my phone tends to switch towers every 5-10 mins, and it seemed like it would drop shortly after flapping between 3g & H (which it does when switching towers).

I'm gonna put her on continuum with jk3 which should solve it, but it's disappointing I have to use JK3, which gives me literally half the speed of JVE.
[Captivate Android Development] shoman94:
I would say they driver that Android uses to communicate. I don't believe that they tune themselves.... they are what they are. They work the same from day one on. Android may be able to fine tune the power it uses but that would be it IMO.
[Captivate Android Development] shoman94:
Well.... I can't speak for the xm/sirius app but using Pandora I haven't had any issues with. I use it often while driving and its been used on pretty much all the modems here. You could try ugkc1 if you want and see how that works out for you.
[Captivate Android Development] caanda45:
The other millon $ question is when we find a good modem are we able or someone able to add it to the list in the op? Is the op still posting here? Would be nice to keep on adding to the list!!! IMHO
[Captivate Android Development] shoman94:
Yes the OP shows up about once a week and puts the modems in the FP. So far they are all there except for UGKC1.
[Captivate Android Development] mcmac7:
Hmm I don't get this problem. Oh well thanks for trying.
[Captivate Android Development] H3llstorm:
That's what I figured. :cool:
[Captivate Android Development] Nucleartx:
On jvk, anybody have a copy of the cwm of kc1?
[Captivate Android Development] LNJ:
It's a few pages back.
[Captivate Android Development] shoman94:
EDIT: Yea I tried it again.... it has great speed but the battery issue isn't good. The dialer is causing a battery drain....
[Captivate Android Development] Nucleartx:
Thanks, xda app cuts the filename off and couldn't tell what it was.
[Captivate Android Development] shoman94:
Yea... I've had that happen. Usually turning it in landscape takes care of that. I take it you got it?

KP1... this modem is on crack. I hit a down/up of 3.8/1.8 and GPS locks to 5 meters within 5 seconds. And battery seems to be holding up quite nicely, I'm running Cog 3.0.1
[Captivate Android Development] davwman:
You mean modem and yes it is very nice so far
[Captivate Android Development] chrisz5z:
KP1 speed is on par with JL2/JL3, but for me GPS wasn't so great.
[Captivate Android Development] hamburgertrain:
oops. it slipped. >.>
[Captivate Android Development] EGBTMagus:
I'm using KP1 and its fast but for some reason my upload is about double that of my download. I can download at 900kbps but my upload is at 1800kbps... kinda weird.

EDIT:

Forced 850 and its blazing fast now, get 2mbps easy from a Texas server, im in MN.
[Captivate Android Development] davwman:
No prob. J/K around.
[Captivate Android Development] skatcat31:
Ended up flashing back to telus with speed mod. I like my 6mb dl
[Captivate Android Development] jaxf250:
Thanks for posting KP1 - will be testing for the next couple days. So far my signal strength is better at home (a weak area to begin with) and download speeds are double for me - rockin'.

Early GPS testing is about the same as jk4 but real test will be outside driving around.

Too early to say about battery life.

via my Captivate running the latest stable flashy bits I could find
[Captivate Android Development] Aus_Azn:
Quick testing of UGJL2 (my stable) and ZNKP1 has led me to conclude the following.

ZNKP1 has a better download speed (4.6-5Mb/s as compared with UGJL2's hovering between 3.8-4)

UGJL2 has a marginally better upload speed (1.6Mb/s vs 1.5, both are very consistent)

LBSTest and Navigation are both showing UGJL2 to be better, locking 10-25m in my house as against ZNKP1 flipping between 15-50m. Will test while driving later. Lock speed is about equal.

I tend to disable HSPA anyway due to the vastly superior battery life, so I don't really know which modem I'm going to keep. Basically, let's see how GPS does in real-world testing. I'll update when I've tested. And I get faster speeds on UMTS than HSPA in my area.

EDIT: ZNKP1 has horrible accuracy as far as I'm concerned. Thus, it's worthless. UGJL2 it is.

EDIT2: More focused GPS use shows that UGJL2 has trouble tracking, whereas ZNKP1 has more trouble getting a lock in the first place. So, I guess ZNKP1 is a bit more reliable.
[Captivate Android Development] menriquez:
i know this is a total n00b question, but can someone point me to a post where they explain how to install these modems into different ROMS??? ive been searching for a half hour and have other work to do...

very appreciative...
[Captivate Android Development] m7ia:
Usually use clockwork to install the zips, see this thread http://xdaforums.com/showthread.php?t=835272
[Captivate Android Development] menriquez:
oh yeah wow....never thought to use the zip to install individual modules thought ya had to install entire ROM...after peeking thru the zip file i see exactly how install works and see how it can be used to install small pieces of shebang ALONG WITH installing entire systems...

thanks for the reply...ready to flash some new modems looks like almost 90% of xda user think UGJL2 is the top modem these days...im gonna give it a try the actual speeds of the stock modem in Continuum 1.2 GT are far below the posted numbers of UGJL2...

it remains to be seen of they work in my area....again thanks...

KP1 modem is giving me a roaming message on Rogers Captivate >.>

Back to JL2 I go.
[Captivate Android Development] cgi101:
Does KP1 default to 850 or 1900?
[Captivate Android Development] stevesteveLA:
I believe it was set to 1900 initially when I flashed Andromeda, which uses KP1.
[Captivate Android Development] Pirateghost:
it defaults to whichever is strongest in your area. for me its 850
[Captivate Android Development] mgfjd:
ZNKP1 is my favorite modem so far..Samsung sucks making software. After, trying so many modems ZNKP1 seems to perform ok. My area has UMT 1900, 850 and GSM 850 and 1900 ATT. During peak hours my phone needs to fallback to GSM before dropping the call. None of the modems I have used so far was able to perform the handover without dropping the call in a congested area.

Samsung modems are too aggressive and do not handover the call on time.

Going from a 3g to a 2g area it works fine.
[Captivate Android Development] movielover76:
KP1 seems like a winner

3.2 / 1.7 upload 180ms ping, highest speeds I've ever got.

GPS locked to 11 satelites in 10 sec

Signal strength increased dramatically.

Big improvement in internet speed and GPS lock time over JK4

Will be doing further GPS testing on the road tonight.
[Captivate Android Development] simulatordos:
Awful sound quality on the other end using ZNKP1

Back to JL3 the once and future king.
[Captivate Android Development] SAEVARM3:
If I choose 850Band I have no Service :/..... I have to choose automatic to get any service. In automatic it says "WCDMA 2100 Band 1" .... is that bad or what?
[Captivate Android Development] devz3r0:
Added I9000UGKC1 to the OP (first aries modem of 2011)

Timestamp: 2011-Mar-4 11:25:39
[Captivate Android Development] shoman94:
Yup... so far so good. It has some decent speed initially good sound quality.
[Captivate Android Development] Nucleartx:
Flashed kc1, back on jvk after 20 tests and only 1 over 3mbps. Most were around 1mbps. Hit my all time high earlier today@ 4.85mbps on jvk. So I'm sticking with it for now.
[Captivate Android Development] shoman94:
There is no doubt from me that it is slower than JVK but I'm hoping it will be overall better than other 850 default modem available.
[Captivate Android Development] devz3r0:
This UGKC1 seems to be over-sized, any idea exactly how it was ripped? Not trying to brick anyones phone
[Captivate Android Development] shoman94:
Not sure.... It came from the i9000 forums from a user that updated through Kies.
[Captivate Android Development] devz3r0:
If you notice, every single modem so far has been exactly (12,582,912 bytes)

The UGKC1 that was supplied is (13,107,200 bytes). Could be legitimate, although I don't know why it would change now.

Apparently /dev/block/bml12 isn't exactly 12,582,912 bytes (thank God it's bigger) else you would be flashing a file that's bigger than the allocated space and it would probably fail / brick :-/.
[Captivate Android Development] geokilla:
I'm on UGKC1 and didn't test it much. However I find my phone to be a bit louder. As for the data speeds, well it doesn't bother me much. As long as it gets through my daily usage just fine, I'm happy. For me, what's important is the signal quality and call quality. Battery drain is important too.

And Samsung needs to stop scamming us with their naming. KXX is supposed to be 2011. JXX is supposed to be 2010. Stupid Samsung can't even get a simple thing like that straight.

Btw we really need to get this thread stickied and renamed as the new modem thread. The one that's currently stickied is old, inactive, and outdated.
[Captivate Android Development] LNJ:
I reflashed it and it works just fine. It won't brick your phone.
[Captivate Android Development] shoman94:
The only other modem I've seen that exact size is the JI6 modem from AT&T's beta release of Froyo.

Interesting..... I wonder what the difference is.
[Captivate Android Development] shoman94:
Not sure what you mean.... JVK was packaged on March 20, 2011
[Captivate Android Development] devz3r0:
:) that has been mentioned a few times actually, I just haven't been able to track down an active mod to make it happen :(.

If you feel the same send a message to Mr. Clown, maybe if they see enough people asking it will happen faster ;). Trying to get the old poll removed too :/
[Captivate Android Development] timn2bama:
I was reading you tag lines. Where you get KP5 from? I want to try it. I have KP1 installed.
[Captivate Android Development] shoman94:
DAGR8 has a KP5 based ROM in this section.

EDIT: Located here: http://xdaforums.com/showthread.php?t=974738
[Captivate Android Development] {Angel}:
The difference is that it was extracted from the nand partition of the phone which means you get a file that is the same size of the partition. It wont brick anybodys phone. If you check the cwm file i shared the modem.bin is the same size as any other modem.bin you'll find. But its safe to flash the original as supplied, only the purist in me made me truncate it.

Edit: Looks like I posted the non truncted file. It doesn't make a difference really.
[Captivate Android Development] geokilla:
Had this discussion a couple pages back and I had no info to back it up. Now I got the info to back up my reasoning on why JXX is 2010 and KXX is 2011.

The Wave and Galaxy S uses a similar naming for its firmware and stuff. As shown above, JXX is 2010 and KXX is 2011. KC1 could mean it was released in March 2011. JVK.... some random month in 2010.
[Captivate Android Development] LNJ:
I was a little disappointed with the speed of kc1 earlier today. But this modem flies during non peak hours. I was getting over 4mb download speeds.

So far I'm liking it!
[Captivate Android Development] perosredo:
+1

I think the problem is with Speedtest as all the other bandwith-consumption I did earlier was very smooth and Speedtest only picked up now.
[Captivate Android Development] EtherealRemnant:
Where the HELL have they been hiding this magical KC1 modem? 850 out of the box, whereas JPP wouldn't connect to 850 if its life depended on it, I got **2300** upload speed (most I've ever seen before is about 1600, supposedly an at&t issue but obviously not since I was using JL2 before this and it tested 1577 immediately before this modem flash) and I got over 2000 download. This may seem like nothing to most of you but in general, I am lucky to get 500kbps download speed with JL2 or JK4 and JPP was just a joke since 1900 is almost entirely decommissioned in Aurora.

Now I need to see if the phone still drops to EDGE and occasionally GPRS when I am on calls... That's really been pissing me off and making me want to get another phone. It will hold an HSPA signal until I get on the phone, then its all over within seconds.
[Captivate Android Development] EtherealRemnant:
And we have a winner! Phone dropped from HSPA to 3G when I was on the phone but it did NOT go to EDGE, GPRS or lose data entirely. KC1 modem is the holy grail!
[Captivate Android Development] disellusional:
battery life?
[Captivate Android Development] grkmaster:
Speed with kc1 from a nj server not NY also with battery at 91% with barely any usage, mostly idle from full charge 5 and a half hours

edit: wrong picture... now correct one
[Captivate Android Development] EtherealRemnant:
I just got off a one hour, eleven minute phone call with at&t trying to get the Inspire and my phone dropped 18% in battery life AND remained on HSPA the entire phone call, something that has never, ever, ever, happened before. Usually at best, I'll end up on EDGE - at worst, I'll lose data entirely and thus will be on straight voice. Crystal clear call quality the entire call with KC1 and the data locked and stayed locked.

This is good news, especially considering I just found out that at&t is decommissioning 2G entirely in May starting from the west coast and moving east over the next several months. I shudder to think what would happen if my phone tried to drop from HSPA to GPRS when GPRS was no longer available. Hello dropped calls!
[Captivate Android Development] fractaline:
YEAH.........

STICKY'D.............

:):p;):rolleyes:

so, kc1 eh.. i don't seem to have time to find anything wrong with one before the next comes out....

my speeds and signal strength keep just getting better, call quality has always been good.

@shoman94... was hsupa enabled on that jh3 modem? i use telstra but never used stock so i've considered trying that modem but always thought of it as a downgrade....
[Captivate Android Development] EtherealRemnant:
KC1 is by far the best modem I've tried for the 850 band, I don't know about the others. But seriously, my phone generally drops to EDGE or GPRS within 5 minutes of starting a phone call and it didn't waver a bit with KC1 whereas JK3, JK4, and JL3 all did the same damn thing.
[Captivate Android Development] Nucleartx:
Got 4.68Mbps down a little while ago on KC1, giving it another try just for Sh*ts and giggles.
[Captivate Android Development] .:Crack:.:
Hey,

will there be any problems when using UGKC1 on my European/International Galaxy S or should i use JVK/JVE (JS8 ROM)?

Thanks
[Captivate Android Development] shoman94:
Yes...hsupa is enabled. The only issue was the dialer was causing a battery drain.
[Captivate Android Development] shoman94:
Well.... 900 is not enabled by default so I'm not sure if you can just enable it. So far it is a very good modem but it's not better than jvk. In fact highway background noise is the same quality as jvk but idling the phone prefers 1900 mhz more than jvk. Got more testing at work today.
[Captivate Android Development] shoman94:
F@#kin right... Finally a sticky!
[Captivate Android Development] grkmaster:
I figured, as usual, data speeds in the office at work, always will be up and down. Like right now i barely went over 100 kB/s on dl/ul
[Captivate Android Development] geokilla:
It's all thanks to me! I PMed xtremekilla asking if he knew any mods that can sticky it! Hehe. Well I thank xtreme for passing the info along to his friend/team member who is a mod.

Anyways I haven't done any testing but I'm loving KC1. Gets rid of the roaming message since it's a Bell modem, and it readily switches to 2G when I need it to. Banzai!
[Captivate Android Development] caanda45:
Just put on KC1 an hour ago, and the voice quality and voice volume seem very good!! Downloading changes in my house from room to room. My office is slow and I go into the living room and it is 2 x faster!!! Can`t figure out that one, maybe it is the picture window. I will try it in the car on BT as I have the day off today to play!! Looking good so far.
[Captivate Android Development] shoman94:
What I find funny is that it won't hang on to 850 like jvk does. Because jvk is not even meant for 850mhz. Where I am at work... It's -115 to -110 in 1900 and -102 to -106 in 850. So of course data doesn't work in 1900 with that signal but 850 does. Why the **** these modems operate like this is beyond me. We need someone that can change settings on these. I would do it like mad if someone would come out and expose what the binary settings are in these modems..... It's definitely a step up from all the other 850 native modems but not as good as zsjpg and xxjvk. IMO of course.
[Captivate Android Development] EtherealRemnant:
Weird that I am getting a constant 850 lock with this modem and you aren't. I will try JVK later but the last time I used a modem that wasn't meant for 850, I got hosed and stuck on 1900 (JPP)...

Voice quality, volume, download, and upload are all phenomenal using this particular modem. I can't believe how much louder my phone calls are now.
[Captivate Android Development] shoman94:
They work fine if you flash per instructions in my SIG.
[Captivate Android Development] geokilla:
True that.

I just checked the GSM Status and indeed I am on WCDMA1900. However at home I'm on WCDMA850 so I guess it switches bands when it needs to. As long as the battery life and call quality is good, I don't mind it if it stays on WCDMA1900.
[Captivate Android Development] EtherealRemnant:
I'll have to try that but looking at your testing, KC1 appears to be the best modem overall for speeds and the voice quality I'm getting is stellar so I don't really feel the need to change it. If I start having 1900 problems, I'll just disable 1900.
[Captivate Android Development] LNJ:
JVK used to jump to 1900 for me as well but I never lost data or coverage. So far KC1 seems similar to me.
[Captivate Android Development] markmunsch:
Well, just flashed UCKC1 and the first few speedtests I ran were typical mid-range, 2600kbps down, 1300kbps up. Just ran another speedtest about 5 minutes after flashing...4600kbps down, 1300kbps. Thought this was a fluke so ran 3 more, all still over 4000kbps down, fastest download speeds I've ever gotten. Now to test out voice quality and gps to see where this sits, but so far I'm liking it :D

EDIT: Just noticed the sticky, very nice :D
[Captivate Android Development] MPKO:
"Modem"=firmware of radio hardware. Basically takes care of the lower layer functionalitys like supported gsm/ umts/hsdpa bands, wifi and bluetooth and then these are controlled by telecom software which takes care that all the functionalitys are following the specificafion based on the 3gpp.
