I9000 JPM modem support WCDMA 850 and 1900 bands

I just tested the JPM modem more carefully today after adding the WCDMA 850 to the rest of the 3 bands (COMBI, *#2263#). the addition of 850 Mhz stayed there even after the reboot (with battery removed), and stayed after I flashed in another modem by Odin 3, I guess it is saved in SIM card or other places. I also tested the force selection of the WCDMA 850 Mhz band and check the actual WCDMA band used by (*#*#197328640#*#*)-> Debug Screen-> Basic Info, and can see WCDMA 850 Mhz Band 5 shown (dynamic changing info).

I then took a short trip using Google Maps Navigation with WCDMA 850 Mhz only (no 1900 Mhz band) with my Bluetooth headset. I can hear the sound from headset when the 850 Mhz band went dead (screen showed it, too) several times, but the Google Map did not crash, cell phone did not wigout nor locked during these dead signal periods. After several seconds, the 850 Mhz band went alive again, every thing recovered. At the end of the trip, I check the (*#*#197328640#*#*)-> Debug Screen-> Basic Info and found out it still locked at WCDMA 850 Mhz band. When I return from the trip, I set it on WCDMA 1900 Mhz band only, the signal never went dead during the entire course of 1900 band.

This indicated that I9000 Froyo JPM (also JPK, I guess) modem will support WCDMA 850, 900, 1900, 2100 Mhz if you add (COMBI) them to enable.

awkward... I thought I was posting in the rom's forum. It's tayutama's, and HERE's the link to the modem.
[Captivate Android Development] boomerod:
Nice testing RC. I did not do as detailed a test as you did...instead, I added the 850 using the Combi screen, then selected auto, both in the service mode and through the Android settings. I then went out to make some service calls. I used the Google Nav app in Map mode the entire trip, as well as having my Bluetooth FM transmitter going all the time. I had no issues of any kind.

I believe it's safe to say that using an I9000 Froyo ROM with this re-oriented kernel, along with a Froyo I9000 modem is a winning deal. Battery life is excellent and all other functions work.

My only issues that remain are with Bluetooth: sound quality could be better, although it is acceptable; and, voice commands seem to do weird things to my Q1 headset: when I activate voice commands the phone responds fine, but seems to send a signal back to the headset that lowers the volume all the way down. If I try to adjust the volume during the process it often crashes the headset. I'm going to test BT VC with my old Plantronics Voyager and see what I get there.

--Edit--

No issues with the Plantronics BT. Gonna flash an older firmware for the Q1 and see if that helps.
[Captivate Android Development] pchic:
Thanks
[Captivate Android Development] boomerod:
Just went over there and looked at that...I did not experience that problem.
[Captivate Android Development] psxstudio:
I have to agree... I've also added the 850 in the combi bands and have it on automatic. Everything is working very well with Tat's SuperLite and the reoriented 2.0.1 kernel with JPM modem. Battery life is excellent, rom is stable and fast! (w/o any lagfix atm).

[Captivate Android Development] raychang:
I have observed some problems in running the standalone version of speedtest.net. It often stalled during the upload test, I am not sure if it's the problem of the I9000 modem (Froyo) or the speedtest.net program itself under Android 2.2 platform. I have not seen so often stalls or FC on the same program in Android 2.1 platform. I did tested under WCDMA 850 only and WCDMA 1900 only, and found out it's more prone to stall during the upload in the WCDMA 850 only band.

Another problem the I9000 modem may have is the smooth transition between different WCDMA and GSM band. I noticed that it's easy for the modem to make a transition from WCDMA to Edge when the signal becomes weak, but it seemed to be difficult to make a transition from Edge to WCDMA when the signal becomes strong. I am not sure if the transition between WCDMA 850 and WCDMA 1900 is smooth under this I9000 modem. I don't know if the Bell Vibrant's I9000m will have a better Froyo modem than the JPM modem. From the superficial understanding, they seemed to be the same modem except for the menu selections' default bands.
[Captivate Android Development] Tayutama:
Right so from the few posts i can read that JPM modem is quadband?

In that case ill just include the JPM modem from my I9000 version in the Captivate version.

If someone would post instructions to enable the 850 band ill link to that post when i upload the next version.

Still need to figure out those damn FC issues on SuperLite :(

Howdy. Could someone kindly post a mirror for 2.0.1 for Odin (.tar)? My office in taiwan must be blocking his download link.

I've got a borked 2e recovery screen that won't let me chose with the power button!

Thanks in advance.
[Captivate Android Development] bts0uth:
has anyone gotten z4mod to work with this yet? I tried the online patcher but it gave an error
[Captivate Android Development] Tayutama:
Ill answer this instead of the OP since it's the same for all custom kernels.

The online patches only works with stock kernels atm
[Captivate Android Development] bts0uth:
ah ok thanks Tayutama. Hopefully it won't be to much longer before Voodoo is working on the Captivate
[Captivate Android Development] boomerod:
I believe that if you modify the package you would have to sign it...I tried modifying the package with some apps and the load failed when I went to flash it. IMOP, I think you should just flash the JPM or JPK modem after the ROM has been installed.

--Edit--

Check with Tayutama on this...

Also, you could use Odin or a zip...I used Odin with the modem.bin file.
[Captivate Android Development] boomerod:
Unless someone beats me to it, I'll post instructions.
[Captivate Android Development] boomerod:
Let's hope we get Froyo source code for the Captivate in this century...:D
[Captivate Android Development] loserskater:
I overwrote the modem.bin in tayutama's lite build and it worked fine. I think as long as you're replacing things and not adding/removing things you'll be fine.

Yeah right, i9000 roms are not faster then 2.1 with voodoo.

How to select WCDMA 850 Band

---Edit---

10/27/2010

Please see this post for more information on the 850 band issue: http://xdaforums.com/showpost.php?p=8833581&postcount=165

I may update the insturctions, pending further testing.

----------------------------------------------------------------------------

OP

It seems the best setting for Data for those using a Cappy with an I9000 ROM and modem is Auto (Settings > Wireless and network > Mobile networks > Network mode). That said, it appears that the WCDMA 850 band is not automatically selected in I9000 Froyo modems (although some have indicated it is in the JPK modem, I flashed to it and found it was not selected). Here is how to select it:

1) Go to phone dial Keypad;

2) Enter *#2263# (if you set to Auto, as noted above, you should see [1] Automatic [*]);

3) Select [4] Combi Bands [];

4) Select [8] WCDMA 850 (FDD V) [];

5) Select Add WCDMA_W850 [];

6) Use Menu and select Back (you should now see WCDMA 850 (FDD V) [*]);

7) Use Menu and select End.

You're done. Several of us have tested this and the setting survives a reboot.
[Captivate Android Development] boomerod:
OK, good to know. Thanks.

I was trying to add some apps, and delete a few others.
[Captivate Android Development] boomerod:
Personally, I'm looking forward to an official Captivate Froyo with working BT voice commands. I'd love to see that with Tayutama's theme. And, although we get a bunch of crap turned off cause of AT&T, DG turns it all back on for us in Cognition. Since I could care less about HSUPA, I'll be giving that forthcoming piece of work a good trial.

If I enable voodoo afterwards, it will crash?
[Captivate Android Development] tjsooley:
yes the voodoo will crash it.

how is the rom running?
[Captivate Android Development] bts0uth:
Wow this was pretty stressful. I have Tayutama Lite version installed for Captivate and from what I can tell, this reoriented kernel is already included in it (i think). I live in an Edge only area and the phone was working perfectly in every aspect but I went to town where it is 3G and my phone kept soft booting over and over every ~15 seconds. It would come back on and I would unlock the screen then it would do the vibrate thing and reset again. The data icon kept going from 3g to H and thats all it was doing in between the reboots.

Back home again and it works fine. I just flashed the modem from JPK that was posted earlier but i'm not sure thats the problem. First time I have tried using an i9000 rom
[Captivate Android Development] jhnstn00:
JP6 full rom with voodoo:

Download speed at 2.9 and up at 1.3Mb/s (very nice as my normal is 0.4) on Android speedtest app.

Battery drains pretty fast and I cant clear battery stats.

Normal problems:

Power button does not work in recovery

home button acts as back (use task os to get to home screen)

screen rotation is messed up (keep it on non-auto rotate)

Voice reception. havent tested.

I Dont use bluetooth.
[Captivate Android Development] tjsooley:
you are not using the reoriented kernal you are using the i9000 kernal that is why you are using voodoo.
[Captivate Android Development] spook:
Hi, I'm sorry if this isn't the right place to ask this question but here goes:

I've really been hoping that I can mount a samba share on Captivate but that would take a custom kernel compiled with the cifs module.

Is it possible to compile cifs into this kernel?
[Captivate Android Development] Disgustipated:
Would it be alright to use this with Cognition beta 7?
[Captivate Android Development] boomerod:
Many people have been doing just that. In fact, DG included it in the new Beta 8 that was released today.
[Captivate Android Development] bts0uth:
I'm missing something, what's the point of using this on a non i9000 rom?

Posted from my Captivate
[Captivate Android Development] id10terrordfw:
HSUPA, of course.
[Captivate Android Development] boomerod:
Don't worry, that escaped me earlier when I asked the same question. I don't do much uploading so it didn't occur to me that someone might want to do this. Lovely AT&T trying to get around providing us the full experience of this phone...like their so-called GPS fix update (JH7) which did nothing more than turn off stuff they missed turning off in the OTB firmware. Samsung and AT&T are a match made in hell...

--Edit--

Still love this phone; just wish Samsung would make it a higher priority than they have and AT&T would stop trying to screw people. This phone has tons of potential and the sleek design, IMOP, is unmatched.
[Captivate Android Development] hashish16:
does this solve the tower handshake issue which creates the screen blanking?

If it does, how can I flash just the modem.bin file? I had problems with the JG8 modem, so I went to the JPM modem without HSUPA
[Captivate Android Development] tjsooley:
jpm has hsupa

if you do that all your porblems will go away.
[Captivate Android Development] hashish16:
I haven't had any of the problems with the JPM modem as I did with the JG8 modem packaged with the kernel. I tried your settings with the JPM and it slowed things down actually.

*just tested the JPM modem, I don't think it has HSUPA. Only got 500kbps upload, where with the JG8 modem I was getting close to 1-1.2mbps (same location).
[Captivate Android Development] boomerod:
It HAS HSUPA...I've tested; check page 29, I think. All I9000 modems have HSUPA.

--Edit--

Way off on the page...here is the link to my test pic:

500kb/s is hsupa..i believe without hsupa uploads are capped at less than 300kb/s
[Captivate Android Development] tjsooley:
I got up to 1.9 megs upload with it avarage 1.25 megs
[Captivate Android Development] boomerod:
I'm not sure I follow you...the reason for adding the WCDMA 850 band is so that in case you are in a area that would use this band it will be active on your phone. It is the only band that appears to NOT be activated by default. So, once you add it you will have all bands available for GSM and WCDMA.

Download and upload speeds will often vary, I would think, depending on the network load at that time, maintenance, etc.

[Captivate Android Development] TheTodFather:
Sup, i know it in here somewhere but could you give me a detailed walkthrough on adding in that band. Ive seen it in the debug menu but didnt know how to turn on or if it would stay? thanks

ah i see it says automatic with a Astrix confused on what to do

Ok i figured it out.

Open sgs tools go to debug / phone controls/ network control/ band selection/ combi bands/ click on wcdma 850/ click add wcdma ...you done!! easy as pie

which brings me to another question...what bands are stictly ATT because if we are on bands that do not pertain to us then wouldnt that waste battery?
[Captivate Android Development] boomerod:
Well, good point. AT&T uses 850 and 1900 in the US. I don't know if having other bands selected would consume more battery. However, I've adjusted my settings to only 850 and 1900. Posted is my speed test at 11:40PM, CST, in Dallas, TX.
[Captivate Android Development] raychang:
You can add all the bands, but at any moment of the time, the modem will only pick one of the band of your choices based on the signals available at your location. 2 days ago, in my area both 850 and 1900 signals were present, I can select WCDMA 850 only and the dynamic debug screen info did show that it was using WCDMA 850. Today, I guess AT&T switch off the 850 band in my area, even if I selected WCDMA 850 band only, it eventually pick WCDMA1900 instead. Sometimes, it said no signal when I choose WCDMA 850 only today. If you choose all GSM and WCDMA and both WCDMA 850 and 1900 signals are not present, it will fall back to the GSM signals if they are present. No extra battery will be used for more than one band.
[Captivate Android Development] hashish16:
Well I installed the JPM modem and I haven't noticed problems yet. Only one "Refreshing Sim Data" message that I've noticed. Super happy with Froyo, thanks for all the hard work!

Side note, does anyone know how to get the speed dial view of the apps menu? I've done it by accident a couple of times now and I can't find out how I did it.
[Captivate Android Development] hashish16:
Another thing, has any one using Tayutama's ROM been brave enough to install Voodoo 5 preview on it?

No we need someone to build it into this reorienent kernel for us to use. I can't wait to try it though seems like we haven't got a new version of this kernel for a couple days so maybe he's working on something nice!

Just need a little help

I downloaded I9000 Open Markt Froyo.rar from the I9000 forum.

The instructions for the I9000 are to flash with Odin3 putting

I9000XWJP6-REV03-ALL-low-CL618121.tar.md5 In PDA

MODEM_I9000XXJPM.tar.md5 In Phone

GT-I9000-CSC-XENJP2.tar.md5 In CSC

So my questions are these:

1) Can I flash without CSC?

2) Will I loose my 3 button combo? (I fixed it with the SBL doing update.zip If I loose DL mode then I cannot reflash this update.zip because of recovery 3e)

3) Before flashing, could I replace the ZImage in I9000XWJP6-REV03-ALL-low-CL618121.tar.md5 and repackage it for Odin? (I'm on WinXP, I'd love some instructions) So that I have the correct kernel from the get go?

4) What did you use to root JP6?

THANKS!

Edit: From http://xdaforums.com/showthread.php?t=794425 I got the instructions to replace both zImage and Sbl.bin with the correct versions. I'm going to try later and report.

Edit 2: Bricked my phone :( It flashed ok, when it rebooted it got into 2e recovery, selected reboot, now it wont turn on or go into recovery or download, so DON'T DO IT THIS WAY
[Captivate Android Development] Disgustipated:
Ok so every time I try to flash this ROM, it gets stuck @ Zimage and doesn't flash the kernel. What am I doing wrong? I put it in PDA and start the flash and it doesn't work. I even tried adding the 512 pitfile... no go.

Edit: I did this with RyanZA's OneClickLagFix installed. Do I need to disable this? I can't get back into Android... so am I screwed or what?

Reversed upright compass

Per my signature, you can see I'm running Shep's rom along with the reorient kernel.

Tonight, I used some of my compass apps (magnetic, not GPS) for the first time since switching to this configuration. I was shocked to discover that, when held in an upright position (edge facing the sky), the compass was reversed; north is south, south is north. Yes, I know how to calibrate the magnetic compass, my compass has previously always worked without error.

When held flat, such as on a table, the compass suddenly reverts to normal operation; north is north. Pick it upright, and the poles appear to reverse.

On the hunch that it may be related to the reorient kernel, I flashed in another (non-reorient) I9000 kernel.

Sure enough, the compass now works in both orientations.

Can anyone else confirm this upright compass problem when using an I9000 rom and the reorient kernel?

Thanks for any input.
