Rogers JI2 Modem.

Has anyone had problems flashing the Rogers Modem and using it on at&t 2.2? When I flash the modem file I get Edge and able to get Data, but when the phone switches to 3G it doesn't work, and when I use *#0011* I see that the phone is on 1900band? By the way I'm in Detroit/Windsor area in Ontario. I also know Rogers is using HSDPA, because originally my phone has an H when it does use it not 3G, this was before I flashed to AT&T 2.2. The Rogers ROm has this H when it's on HSPA and or HSUPDA.

I seem to get better reception with jj4 (cognition b8), at the cost of my gps not working at all. To be honest, it wasn't working well enough on ji6 to consider it being functional anyway.

Sucks that we have to choose between gps with the i9000 roms or battery life with the captivate roms. :(

good modem for nexus s rom?

im using jl3 but i feel it eat up battery can any body suggest any modems who are running nexus s rom.
[Captivate Android Development] cachookaman:
Running JL3. Longest battery life I've been able to get is 13 hours with normal use.
[Captivate Android Development] rootnik:
I've given up on trying to find a happy medium between GPS and battery. I just have to learn not to play with my phone as much when I don't have a power source accessible. The speed/gps combo of the i9000 roms outweigh the battery life issues IMO. To many useful GPS apps out there to ignore them.
[Captivate Android Development] maxjivi05:
I get 400KBps + / - a few most test Download and around 150-170KBps Upload speeds using "update.tljl3.modem" also battery life isn't bad at all, it's by far better then what I normally use but then again I use the 1280MHz OC/UV Kernel.

Plus GPS Works Awesome using the google gps tweaks zip from the other threads.

400KBps is crazy fast for 3G Service, that's right around 4Mbps.

Guys,

Why does my band selection keeps changing by itself? I am suing JK4 modem on ATT captivate with Cezar 2.2.1 Froyo ROM (I9000). Using *#2263#, I set the band to Combi Bands. But now I am seeing that it is set at WCDMA band.

[Captivate Android Development] android158:
what is JL5? I dont see it on the list in the op.
[Captivate Android Development] RMGeren:
jL5 dropped right before Christmas. Afaik, there is an issue with gps on this modem, so jl3 is the current modem for me.
[Captivate Android Development] cocchiararo:
there are now (well, the first one is old :P) DXJPA, DXJPB and i9000BVJJPA.

The las one is sure to be 850mhz one, since the i9000b uses those bands.

Any ideas on the first 2 ? the DXJPB one came from the 2.2 ROM that droped today, SEA countries they said, DXJPE was the rom.

so this is prolly a dumb question but im still trying to figure out all of this stuff. So i currently live in an area where AT&T doesnt have a tower, but verizon does so. i cannot get service on my captivate but my friends who have verizon get 3g. is there a way to get a modem that picks up the verizon signal so that way i can get better service. idk if im using the correct terminology but ya. if someone can help that would be greatly appreciated. i am currenty running assonance 5.2 and jl3 modem.

So ATT just announced that they are going to enable HSPA+ to all handsets. So does that mean we might be able to see an actual modem file on ATT build very soon with HSPA+!?!????
[Captivate Android Development] jaxf250:
I would hope so. Looks like the Samsung Infuse handset would have it. My Q is: do our SGS-class phones have a modem chipset that can support HSPA+, or just HSPA?
[Captivate Android Development] existz:
If im not mistaking but isn't HSPA+ ATTs 4G? If so, then no, only newer phones "4G" capable will only support it...then LTE on ATT isn't expected till 2013 (5G?)...so HSPA+ is their 4G

[Captivate Android Development] jaxf250:
Whoa. Deep dove into this stuff and my head is spinning.

If I could simplify it, the HSDPA/HSUPA or HSPA+ stuff from AT&T is all just Rev. 5/6/7 of 3GPP with different MIMO antenna and QAM modulation features.... http://www.3gpp.org/HSPA

http://en.wikipedia.org/wiki/3GPP

HSPA+ is not LTE. LTE is Rev. 8 of the 3GPP spec. And not sure if the new Samsung Infuse phone will support Rev. 8 (it will support Rev. 7 HSPA+ it would seem).

I was confused before by their marketing lingo and sales-speak. OK. So without a chipset that can support Rev. 7 of 3GPP we are stuck with SGS 9000-class phones that can max out at 14.x-ish Mbit/s. Not bad. Not 4G/LTE either. OK, I can goto bed now. Brain is full.
[Captivate Android Development] grkmaster:
So the 4g phones that are being released are not going to be LTE compatible? Thats some bull**** marketing to me. Most people wont know the difference but a good amoutn of us know the difference. I am really debating on Verizons LTE depending on their pricing and if they still are keeping unlimited data on their plans.
[Captivate Android Development] awolwalker:
I was looking around last night and att intends to use hspa+ and lte. They'll launch hspa+ this year but lte is still far off. Like always they're doing a half @$$ed update to keep appearances that they can keep up.

I am using jj4 captivate rom. when i use *#0011# it show wcdma 1900 not 850.
[Captivate Android Development] beerbaronstatic:
Doesn't matter what modem i use it seems to prefer the 1900 band, I can manually force it to 850, but should I bother?
[Captivate Android Development] dolph8886:
I'm no expert here but it is my understanding that AT&T uses both WCDMA 850 and 1900 bands, so depending on the location you may be using the PCS WCDMA 1900 band.

You need a modem capable of both to utilize the network as some areas (seems mostly rural) use WCDMA 850 with AT&T.

Someone please correct me if I'm wrong here.
[Captivate Android Development] sremick:
All the marketing involving "4G" right now is basically bull****. No one is really doing "4G". Not T-Mobile, not Verizon, not AT&T.
[Captivate Android Development] geokilla:
Isn't the 1900 band worse than 850 in terms of penetration and stuff?
[Captivate Android Development] beerbaronstatic:
I have no ideathat's why I was asking if it was beneficial to force to 850
[Captivate Android Development] dolph8886:
850 does have better penetration and farther reaching as to why its mostly used in rural areas, if you have a good signal on 1900 it would seem there is no reason to force 850.

Need some assistance folks.

I have Captivate SGH-I896 on the Rogers network (Canada).

I just flashed to the Ultimate v5.6 XXJPY ROM. Problem is that my phone will not accept any incoming calls now. It rings for a second and then the signal goes dead and then resets. I can make calls and access data, but can't get incoming calls.

I"ve tried using various modems including TLJL3, UGJK4, UGJK3 and UGJL2 - all with absolutely no luck.

Any thoughts?
[Captivate Android Development] grkmaster:
So any modem i use lately it seems to prefer 1900 band and my speeds have suffered.. I used to have a good connection but now i cant find the correct modem to use. not only that.. I can go losing like 10-12 percent battery over night, sometimes only 4 hours and sometimes in a 8 hour span.. It really sucks. Right now i have wifi on and my battery is barely dieing. Ugh! getting frustrated when I go out that i have to watch out how much i use my phone

I just tried flashing the tl3 modem into perception and it said that I was roaming on my phone. I reinstalled perception and the roaming message went away. Is that normal?

I'm on fido in canada.

Edit: Using UGJL2 now and I'm not sure if my signal and stuff is any better. However the roaming notification is gone now. I am also having a hard time getting a GPS signal. Stood there by the window for 5 minutes and I didn't get a single satellite in the LbsTestMode.
[Captivate Android Development] drumega:

[Captivate Android Development] Pirateghost:
Use Odin 1.7 or use a flashable zip file and drop your modem.bin into the zip in the updates folder
[Captivate Android Development] geokilla:
Just an update on this. Getting dropped calls like crazy while running stock Serendity 2.0 with UGJL2. I can only make calls, can't receive. I don't know why that's the case. Could be the modem... could be the ROM.
[Captivate Android Development] RyanFromQA:
Most of them come in a "flashable zip" which lets you dump the file on your SDcard root, and use Rom Manager (aka Clockwork Recovery Mod aka CWM) to flash it. Takes about 5 minutes (longer if you have it back up your rom)

Note about TLJL3, I didn't realize that the JL3 modem was included in Cognition 2.3B8 and I flashed the one from the thread linked in the OP. I couldn't make or receive any voice calls. Actually, I could make and receive them but the mic and speaker didn't work. Neither earpiece, speaker, or bluetooth. Very strange.

I flashed the JI6 AT&T modem and it works fine now (though I just saw that JJ4 is actually higher alphanumerically than the one I flashed, I'm happy with it. I got 3.3Mbps with HSUPA/DPA.
[Captivate Android Development] existz:
The reason you most likley had problems was cause you was using an i9000 modem (jl2, jl3, jk3, jk4..etc) on a Captivate kernel, its best to use i9000 modems with i9000 based kernels (hardcores, setirons, or firebird kernel)
[Captivate Android Development] grkmaster:
Is JI6 the only non HSPA+ modem? I might go back to it and rather have the better battery life.

I can flash it on JPY right?

I tried the JL1 modem and it makes my phone shutdown randomly. I did not notice any speed gains either so I went back to JL3....in case anyone is wanting to try it with Serendipity and a Setiron kernel.
[Captivate Android Development] s44:
That's because it is, as it says, a CAPTIVATE modem. You're running i9000 ROM and kernel, so you need an i9000 modem.

(Same for the guy asking about JI6 on JPY above. JPY = i9000)

If you just want to disable HSPA but keep UMTS, dial *#301279# , and select [2] Change HSPA Revision, then turn HSPA off, it will stick thru reboots ..give it a couple seconds to switch to 3G from H
[Captivate Android Development] lrs421:
Confused as hell...

Looking for a little guidance here, perhaps someone can send a little knowledge my way. I've tried JK3, JK4, TL3, JPP and now JL2. Each one automatically enabled 1900 band 2. I used the methods mentioned to force 850 band 5 but each time I did so my speeds suffered. I live in Brooklyn, NY and it's well known that data isn't that great in NYC, but on 1900 I'm getting around 3 down and 2.5 up and a fraction of that when I force 850. Is this correct? I see everyone making a big deal about 850 but it's just not making sense to me. By the way, JPP has given me the best performance of the group, go figure.
[Captivate Android Development] grkmaster:
I love my 2.2.1 !! lol so smooth and fast! :-) I cant go back now lol

Thanks I will try that. Hopefully that works out for me.

[Captivate Android Development] bames:
for what its worth my best gps tracking performance has been with my build 1007

[Captivate Android Development] lrs421:
Anyone? This time I got a modem to stick to 850 in first flash, after flashing back to stock by the way. Speeds still suffered. 200 KB down, and found a several all the way in MD, two states over. After switching back to 1900 I was back at 2 MB down, am I alone here? Currently running jl2.
[Captivate Android Development] s44:
Well, HSPA is HS*D*PA (which the AT&T modems have as well, and directly affects downloads -- d=downlink) as well as HSUPA (which only international modems have, and only indirectly affects downloads -- u=uplink). So turning it off entirely will throttle you pretty bad.
[Captivate Android Development] grkmaster:
I ended up actually rebooting to see what id get and man what a different.. my dl was like 7 kB/s and upload was like 140 or so ... so now i dont know. Maybe Ill have to switch to a captivate kernel
[Captivate Android Development] RMGeren:
I'm on AT&T, Charleston, SC. Using JK4 modem on Perception 10.1 I am almost always on wcdma 1900. A quick speed test just got me an average of 1.3mbps down, 900kbps up. my peak download speed was over 2.5 mbps, and one upload test failed.

This is about the same as I was getting on tljl3 modem on the 850 mhz band, so I see no reason to switch unless you're having problems. I find the gps to be better on jk4.
[Captivate Android Development] LimaI896:
Perfect fixed my calling thanks!
[Captivate Android Development] lrs421:
Ok, so I've figured this out after re-reading the JL3 modem thread. Someone pointed out over there that both 850 and 1900 are HSUPA and some areas are optimized for either/or and that one isn't necessarily "faster" than the other, it's all about location. This explains why I only get edge when locking 850 and things drastically improve on 1900. Since my earlier post I locked myself on to 1900 and have had consistent speeds, much higher than 850. 850 isn't the gold standard for everyone.

Some areas have both for penetration.

In NJ at my house, which isn't the best signal area, I can get both bands depending on what room I'm in my house

near the back of the house near windows or outside, I always lock on to 1900, and I get better data speeds

however if I go back to my room in the front of the house, I'm on 850 about 75% of the time and if for some reason I lock onto 1900 in my room, I have a much worse signal and slower data on 1900.

This leads me to conclude that for the best performance you really need a modem that works with both 850 and 1900, so it can choose what's best for every signal condition you are in, I'm sticking with Cognition 3.02, because a pure captivate modem just seems to produce much better call quality.

It is a phone first and foremost after all.
[Captivate Android Development] lrs421:
All modems I've used do both. But 850 doesn't work for me in terms of speed. Every time I leave it on auto speed bottlenecks when switched to 850. 1900 for me :D

[Captivate Android Development] existz:
You check your modem in Settings/About Phone under Baseband Version...also you cannot use a captivate modem with hardcores speedmod kernel (ji6 or jj4), it will cause alot of issues.. the kernel is a reoriented i9000 kernel, meaning its an i9000 kernel made to work on the Captivate, so you have to use an i9000 modem (jk3, jk4, jl2, jl3, jpd, kp1..etc) check the first page of hardcores thread and read my faq, also you install a modem with cwm, just choose install zip from sdcard and select it...
