Now I might be putting my foot in my mouth, but this just confused the hell outta me! :confused: Isn't it that CWM3 is backwards compatible so it can flash CWM2.X and CWM3, as alot of software is, or is it that that CWM 2.5 is forwards compatible with CWM3, so it can flash CWM2.5 and CWM3?

'Since you have cwm2.5 you can flash either cwm2.5 or cwm3 modems," this means cwm2.5 is forward compatible.... but

"cwm3 is backwards compatible with cwm2.5" this also means it works the other way too.

If that was the case then there would be no need to distinguish the two as they would work in either CWM.

I believe the correct answer is that CWM3 is backwards compatible with CWM2.5, someone please correct me if I'm wrong. :)
[Captivate Android Development] alexige:
I was worried that it would come across as confusing. Sorry for that.

In his case, the kernel he was running was equipped with CWM2.5. As such he could flash either cwm2.5 or cwm3 files from the op.

Now if he was using Talon for example he would be required to use CWM3 files because Talon uses CWM3.

I am able to pick the 850 band and get it to be selected and stay selected after reboots, etc. but whenever it is selected as the only band it still shows WCDMA 1900 Band 2 under the *#0011# menu. I'm confused as to what this means, because I thought if I selected WCDMA 850 if would either have no service or it would connect me to an 850 band. Could someone help me understand this?

I am running JVO on Serendipity 7
[Captivate Android Development] alexige:
You have to do the modem dance found in the OP.
[Captivate Android Development] Felixpau86:
Played with most of the newer modems on the list like kc1 jp9 etc. I find that jvo after dance is the best in terms of speed and stability.

This is for rogers customers in richmond hill/toronto area.

[Captivate Android Development] Geezer000:
The only problem I've found with JV6 is that the noise suppression SUCKS! My wife says that she can hear everything around me but not my voice very well. Not good for any type of noisy environment. I'm back to JVP and JQ1. So far there the best all around modems for me in the London/Aylmer Ontario area.
[Captivate Android Development] Uncle Irish:
I searched the thread for Orlando area and some have said JL2, JQ1, and JK3 gives the best for this area. JL2 seems to be the winner with more votes. I'm wanting to try the new COG 5 but want to get HSUPA. Are there any Captivate modems that can do this yet? Pretty spoiled by the i9000 modem speeds and don't really want to lose that.
[Captivate Android Development] Nucleartx:
JV6 couldn't hold a stream between towers for me, kept kicking me down to Edge or even GPRS in a HSPA+ market. Had to switch back to jk4. Even my favorite JVK doesn't work very well with GB for me at least.

[Captivate Android Development] H3llstorm:
I agree - mostly.

In my experience, modems that worked well on Froyo didn't work nearly as well on 2.3.3 ROMs, and modems that worked well on 2.3.3 ROMs didn't work nearly as well on the 2.3.4 ROM I'm using.

With that, some ROMs have required "GPS fixes", while others haven't, so I'd say that if you're not in the same location as me on the same version of Android as me - and possibly the same ROM as me - no amount of data collected is going to be useful to anyone else.

I'd also say that if you're not paying me to collect data, you can collect it yourself. :cool:

Could we get a CWM 3 of KE1 and KF1 for the I897 in the OP?
[Captivate Android Development] alexige:
They are in the thread if you go back to our android development page and click on the paper clip next to this title scroll through and you'll find them.
[Captivate Android Development] fuze4me:
Looks good so far. Thanks!
[Captivate Android Development] nakedninja42:
I found them no problem, they are about 5 or so pages back and used the paper clip. The point is that if I am on my phone, going to the OP would be easiest for grabbing them using the XDA app. Plus the OP needs to be updated with the new modems like it gets the I9000 modems.
[Captivate Android Development] H3llstorm:
Correction: Cell reception improved with XXJVE, but GPS reception was worse.

After trying out a few modems, I'm sticking with UCKF1. Cell reception is strong, and it made it through an oddly GPS-resistant stretch of road with only a few hiccups (and quick recovery) where other modems choked & died.
[Captivate Android Development] kobik77:
Don't know with with you guys, but JJJV5 gives best performance so far on both categories.

Initial results of KB1, KE3, and KF1 modem test

I tested KB1, KE3, and KF1 this morning. Mind u, that I am in a rural area and was on WCDMA 850 Band 5 at the time of these tests, but thought I would share anyway, just as a friendly fyi.

I'm sure that speeds would b better (especially the upload) if I were to b on WCDMA 1900 Band 2...sooooo, here ya go. And by the way, the number of bars that are seen in the pics are reflective of when I was inside my home and took these pics with the "shoot me" app. When I did these tests I averaged 4 bars and around -89 dBm signal strength... + or - some I'm sure... Pics, in order from left to right, are KB1, KE3, then KF1

[Captivate Android Development] 4-2ndtwin:
And here are some afternoon results of the UCKF1 modem speed tests that I did where I went out and made sure that I was connecting on WCDMA 1900 Band 2 just to see if there would be different outcomes. And as well, I re tested at my home again where I was connecting on WCDMA 850 Band 5 to see if the test would prove better than this mornings.---and it did on the Upload speed at least. Of course once again, these are my results and everyone else's may vary. But just wanted to post as a fyi reference.

First pic on the left is the retest on wcdma 850 at my home and the 2nd pic is the test on 1900, which I was connecting around -67 dBm + or - some...

These last two result pics look as though that is how this I897UCKF1 modem is going to perform on average for me..."ymmv" :D

[Captivate Android Development] GeoMandell:
Are you making any changes to the HSDPA and HSUPA settings in your build.prop? What are they set to currently? I've been going around in circles trying to figure out why my data fluxuates so badly. I can be in the same room on the same modem with the same build.prop settings and data will go from 2-2.5Mb DL to 50-100Kb DL.....is it actually possible that AT&T's network sucks that badly that the change could be that bad from usage around me? Or am I missing some setting or something. I've tried numerous modems and get pretty much the same results.
[Captivate Android Development] geokilla:
Just to report that the other day I had to use GPS and Google Maps with KC1, it couldn't keep a GPS signal unless the Captivate was right in front of the dash where the windshield is. I guess it's time I switch to JK4 or to test the newer modems.

JV5 Vs. JV6 Voice Quality

I did some voice quality tests to see the different between the two modems. JV5 is a clear winner. Feel free to take a listen at my site:

http://samsung-captivate.weebly.com/modem-test.html

As for data JV5 and JV6 are dead even in my location near Redmond, WA (just east of Seattle. Last night around 12:30 AM they both spiked to 5Mpbs down and 1.5 Mbps up. This morning they are averaging around 3-3.5 Mbps down and 1-1.5 Mbps up.

I'm sticking with JV5 for now.

Which "JV5" is everyone talking about?

For me, JJJV5 is great for GPS, but sound quality on phone calls is mediocre, while NEJV5 has much better sound quality on phone calls, but seems less accurate when using my GPS.
[Captivate Android Development] xpakage:
Not my words but from a thread and I did not copy name when making a file on my computer.

Dalvik cache is a place where the Android OS re-compiles the executable programs the first time to optimize them. It does this when you make a major change like replace the kernel/modem. Clearing the Dalvik cache will force Android OS to recompile the apps for the the new kernel.

Also the main data Cache is used by the Android OS at run-time to write temporary files for specific reasons. You want to clear this out so it doesn't re-use the old cached data.

Manually clearing both caches allows the new kernel/modem to be installed in a "cleaner" environment. It's just preventative maintenance.

It constantly lost data connection and would switch between 3G and H frequently. Speeds were about the same as I would find in the JL2 modem. GPS would lock at a decent rate, however it could not KEEP the lock on when I would start driving. JL2 still reigns supreme for me in the NYC metro area.

You need to download a zip package which suits your rom/recovery.

There are packages for cwm2, cwm3 and for cm7/miui.
[Captivate Android Development] melbourne408:
Yes, plus if the modem isn't working the right way and your wanting to install a different one you could extract the modem.bin out of one zip and replace it within another zip, rezip that and flash through cm recovery.
