JK3 modem, loss of all reception, drains battery, requires a reboot - Captivate Q&A, Help & Troubleshooting

So, right now I am using the Axura RC1 CE (I will update later), but I have had the problem described in the topic on various other ROMs using the JK3 modem.
It works fine for a few days (time is random, I have not been able to manually reproduce the issue), then randomly I lose all reception. Switching to flight mode fails, it gives no error, it just does nothing, in the notification bar it just says (searching). I have to reboot the phone to get the phone functioning again.
Anyone else experiencing this on ATTs network, or if there is a fix, I spent the last hour searching and going through the various threads to no avail (or I just suck at searching)..

Did you try the Axura thread?

I'm having the same issue but I've tried Assonance as well and still get the random no service. Tried different i9000 modems as well--anyone know if its safe to use a captivate modem??? I'm guessing no but just want to know if anyone has tried it without borking the phone.

I'm having this same issue as well, that's why I've tried to stay away from the UGJK3 modem, however, it's seems every custom ROM is starting to use it
As far as using a captivate modem with an i9000 ROM, I've tried that also, while it didn't totally brick my phone, I did get random FCs. I've read that is a dangerous path to go down.

I feel the same way. I might try the CogKernel and see if that helps...

Please, please, PLEASE do not post these types of things in Development.

+1 Lets keep this forum area clean .. its just for development stuff guys.

I have had the same issue with all I9000 modems, the only fix that has worked for me is to enter the service menu and force WCDMA 850 Band only. Also, questions should be posted in the question forum.

[this thread is pretty relevant to development - considering the rom chefs are using this modem in their releases and it has a potential major flaw. if the mods find it better to be in Q&A, then please move it - otherwise, i think the right eyes will see it here]
yes, yes and yes!
ive been posting about it in the perception thread, but no one (save for 1 user) chimed in with the same issue.
we both noticed that we both have an issue where we will bounce from 3G to H and back fairly often. this leads me to believe that it could be part of the problem.
i just odin'ed back to stock because my phone isnt receiving incoming calls now.
what i had planned to do was flash the latest perception but use a different modem... but it seems like the only sensible modem is the JK3 (although there is word on the street a new one just leaked?). so that idea is kind of out.
someone here said they were going to try cogkernel2, but i was on setirons and cogkernel2 and it happened with both. it seems to be a modem issue.
i wanted to lock the phone to use 3G only to see if that would help, but no one shared a way how... but reading this post it seems i can do it from the service menu - though i dont know exactly what to set/change to keep it only on 3G. (any help would be great).
so i believe im going to flash perception 8 and see if i can lock it into 3g mode and go from there. this is getting pretty tiring. im hoping if a new modem releases that will help, but i honestly am not sure i can wait since it is making the phone unusable.
below are my posts from the perception thread on the issue.

i searched but did not find...
i see others have had issues with APN force closing. i do as well, but assuming that isnt a problem, i dont mind.
my issue is that after a certain period of time left asleep, my phone will completely fall off the network. changing flight and data mode dont work, nor help. a restart works. this has started a day or two ago, but was not an issue for the first week (give or take). if it is relevant, my network constantly swaps between H and 3G where i live.
i have not found a setting to force 3g (and disable hsdpa) as i figured it was the network hopping that was doing it. am i just missing that setting? anyone else with this issue? (again, i saw people with the apn force close but not complete loss of network unrelated to initial flash)
also, i think that each build should get its own thread. it is VERY difficult to find accurate information on the current build once a thread has 4 builds and 250 pages in it. even with search, it would still be a good idea.
thanks and thanks.

of note: going into wifi settings is also borked. it will eventually time out and FC. i also think that the times my phone has completely lost network and not reconnected have happened more often when charging. but that could be coincidence.

in relation to my post below yours, does locking the 850 band only force the phone to use only 3G, or is HSDPA/HSUPA still enabled but you found the 850 band to be more stable.
this is what my next attempt will be to get a solid platform going.

I've tried different modems other than jk3 and it doesn't fix the problem. Stinks that you've used Cogkernel2 and it doesn't help. I also tried the different band selection in service mode and it also hasn't help me (apparently this worked for some people). If you want to give it a shot do the following:
1. Dial *#0011#
2. menu button then soft back key
3. then phone control -> network control -> band selection
4. good luck!

ugh. that is disheartening. i will try the band lock, thanks.
can you confirm or deny that when you notice your phone goes completely out of service that it has been hopping between 3G and H? it would be interesting to see if we all have that issue as part of it.
also, fingers crossed for that supposed new modem.
/sigh

Yeah this really sucks because these roms are great with this one very big exception. I haven't noticed the hoping before I need to reboot. I have noticed that if I switch into airplane mode once I drop service I can't turn it off.

I had the same issues with Axura and Percetion. I found that switching my network control to WCDMA 1900 only pretty much fixed it. The only problem I had after was that any time I lost service naturally, ie, bad area, or shielded rooms, whenever I came back into a good service area I could never get a signal again. So I would have to reboot.
In the end, I'm back on Cog, 2.3b7 and no issues for about 14 hours now.

Separate radio for 3G?

Are there two physical radios in the Tilt/TyTN II? I ask because I'm experiencing a strange problem that nobody else seems to have seen before. That, or nobody noticed my posts here:
http://forum.xda-developers.com/showthread.php?t=335096
The problem is that phone/data work fine when the phone is in non-3G mode. (In the Comm Manager, available in most recent ROMs, I have disabled the 3G mode, so I'm using only GSM here in the US).
In 3G mode, I'll get a 3G icon (used to get an H, months ago), but will be unable to place/receive calls, and no data connections will be established -- they'll all time out or say that "the answering modem has disconnected."
So, back to my question: is it possible that my radio is partly damaged? Can that happen? I'm not sure how else to explain the utter lack of 3G on my phone.
can't have a damaged radio, you could have the wrong radio for the device and/or version of windows mobile. 3g only works if in 3g area,have it enabled and turned on through comm manager.also make sure you're network settings are correct and make sure phone is set to auto in networks tab in phone settings,not set to gsm/cdma
PS, the search tool/wiki are you're friends since this has been covered too many times

Thanks for the advice. Unfortunately, I've tried everything I can think of, and everything suggested. Nearly ever ROM I've seen, with nearly every radio; every combination of wap.cingular, isp.cingular, etc. The AT&T store thinks the phone is defective b/c they can't figure it out, either. In response to your comments: tried every version of windows mobile and most of the radios available; I'm very much in a HSDPA 3G area (used to get 5 bars "H" all the time); 3G is enabled; network settings are correct; phone is set to auto/auto.
Any other ideas, anyone? I appreciate it!
I've been have the same exact problem. I posted about it about a month and a half ago, but got nothing.
Everything worked perfectly until one day, out of nowhere, 3G stopped working for me. I've also tried multiple radios and ROMs and to no avail. The weird thing is that when it stopped working, nothing had been changed in months.
I know that I'm definitely in a 3G coverage area because I used to get 3G service all the time.
If I turn 3G on, it'll work in an edge only area, but as soon as it switches over to WCDMA, the problems occur.
This is super aggravating.

Well, the good part is, you're not alone. I found another forum online (can't remember where, I'm at work now and I found it last night) were several people were having the exact same problem -- in various countries around the world, including the US.
They had decent luck flashing the stock HTC ROM and then the French radio mentioned on the big XDA radio post (search google for "kaiser radio" and you should see it). However, I did the same and still have the 3G problem.
did you try using a shipped att rom and see if you still have this problem? if the problem goes away, then maybe its just a rom/radio mismatch problem. if it doesnt, then its more likely a hardware failure.
I'm in france, and since few days, i've the same problem, and i haven't change the radio. the phone is going for repair.

As mentioned in this thread, some shipments of the TyTN II have faulty hardware with broken 3G support.
No patch or driver update can fix this because it is a hardware problem. I experienced exactly the same issue with my first TyTN II and finally replaced it with a new device which works flawlessly out of the box.
I believe you should also better get your device replaced if you ever want to use 3G.

Lots of 3G dropouts!!

Hello all,
My issue with this phone has been mentioned here: http://www.google.com/support/forum/p/android/thread?tid=384f4daca48e10b1&hl=en
My basic problem is that atleast 4-5 times each and every day the 3G connection suddenly drops out. As the link says, I see the "up arrow" blinking, but no action from the "down arrow" next to the 3G symbol on the top right corner of the phone. At this point, all apps complain about no network connection. About 45-60 seconds later the connectivity is restored automatically, and I can happily do anything on the Internet again.
I've had the phone for 1 week and this happens regardless of location or signal strength. So I've had this problem at work, at home, while driving etc. The dropouts also occur even when the number of bars indicating signal strength is 3 or 4.
These constant dropouts are really infuriating and I'm not sure if it's a network problem or device problem. Has anyone else had this? I'll be very grateful with any suggestions.
Thanks.
same here, I dont know if this caused by my ****ty provider.
I'd like to try new radio but it seems it still has problem with bluetooth
I had this problem too, it was very frustrating. However the new radio 5.08 appears to have solved the issue for me (I don't use BT currently so can't report on that aspect)
Ask a work around, try setting your phone to "WCDMA Only". That improved things for me previously.

I have also had this problem and I am on stock FRF91. It really slows me down when I need to quickly perform a task that's data related.

This is exactly what I'm doing.
The internet oon the phone barely works on 2G, so I lock it on 3G only mode.
Have this problem on stock.
Also drops calls when it goes down to 1 bar (in areas where another phone with the same provider will have 2-3+ bars)
This has been discussed in detail here

Thanks for the replies guys. So if a mod completely gets rid of the problem, that means it's a software issue right? What's this radio 5.08 that solves the problem? Can I apply this chagne without rooting?

[Q] Wi-Fi To 3G

Hi,
Got a really annoying issue with my Nexus One that has been happening since the Froyo days, when I leave home to go to work I turn the Wi-Fi off on my phone to save battery. Sometimes I use the widget sometimes I go through the settings.
The problem is that the 3G doesn't alway's kick in, the only way for me to get 3G working is to turn my phone off and on which always works.
Any suggestions on why this is happening and how to resolve them?
I am running Stock Ginger Bread on my Nexus One on the the Vodafone network in the UK.
Try checking your signal strength: *#*#4636#*#*
You can try to enable 3G only and see if you can keep a signal.
My signal is sometimes intermittent due to topography. Stupid flat Ohio. Haha

Thanks, it won't be that though because once I turn the phone off then back on it's there. Also once I turn W-Fi off and 3G doesn't kick in, then it won't do untill I restart. Also another reason why I know this isn't the case is because even when I do this at work 3G doesn't kick in and there is a Vodafone 3G mast on the roof
never seen this problem before, but it sounds like something that might have to be fixed by doing a full wipe and reflashing your ROM. i know its drastic, so maybe do a nand backup first. then flash and see if the problem remains. if its still there, than just go right back to your backup and no harm and nothing lost. worth a shot.

I'm on a stock Nexus One unrooted so I shouldn't have to Root to fix an Android problem. Never Rooted before but considering it.
I got the exact same problem with Froyo and Gingerbread ROMs, can't remember if I had that issue with MIUI ROMs, but definitely with CyanogenMod ROMs.
Instead of rebooting the phone I suggest switching flight mode on/off it's faster than a full reboot
Haven't found any real solution yet and always thought I'm teh only one with that problem as I couldn't find any other person with that issue. Right now I'm testing different Radio/ROM combination and if that doesn't work I'll need to check if any app is causing the problem.
Any chance you are using Tasker?

[Q] wifi keeps switching on and off

Hey all,
since a couple of days I have a problem with my wifi, it keeps switching on and off (I can see the checkbox activating and deactivating, every couple of seconds, at the moment it is unchecked and says "error")
as I said, the wifi worked before
I am running cyanogen 7 (http://android.doshaska.net/cm7) on Milestone
- But I have also tried MIUI, with the same problem
does issue sound familiar to anyone?
Maybe it is an app which force turns my wifi on/off, is there any way to check which one it is (as far as I know I don't have an of them, eg juice defender, tasker installed)
Many thanks
Have you tried other WiFi networks? Because the same error being reproduced across two different ROMs seems a little unlikely.
Well, the problem is that my wifi doesn't stay on long enough (just a couple of seconds) to scan/connect to any network.

wow, i just logged in to search for this issue myself. I have that same issue across multiple roms also. The one that did work was the Telus Lite Eclair. I liked that one, but of course I wanted to check out others. Each one was the same as you describe. Wifi scans, disconnects, scans, in a loop.
I have done searches on google for wifi disconnect loop android, and seen some stuff about kernals and stuff that is over my head at the moment. If some one has an idea on how to get it working that would be great.
I wipe before any install, I've went back to stock and it works, everytime I went to the Telus Lite one it also always worked. I dont know if theres a clue there or not?
Im on an Telus milestone in Canada, on Telus network if that makes a difference.
And since I think this is my first real post, Thanks for the work guys.
Not sure if this would work, but this is the first result that popped up: http://www.droidforums.net/forum/koush/75782-wifi-disconnect-loop-cm6-final.html
EDIT: People are saying that Hidden SSIDs and MAC filtering can cause problems when trying to connect to the WiFi network. Try forgetting the network, making the network visible(protected if you wish) and reboot the phone and try again.
ok, time for a stupid question...
where do I find suitable kernels?
I can't find anything about this (roms and kernel tweaking is a is pretty well documented though)

[Q] Mobile data connectivity issues, which radio?

Hi guys (and girls),
I'm going slightly mad trying to figure out a stable setup for my O2X. I have been switching between the latest CM7 nightlies, and MoDaCo FR19. In general, CM7 gives me quite frequent black screens, and FR19 seems quite stable. However, there is one issue that is present in both ROMs.
I am unable to get a stable mobile data connection when I switch from WiFi. Sometimes it works, and sometimes it doesn't. To get it to work again, it sometimes works to switch to 2G only (and possibly back again). I have tried several different radios recently: 218, 606, and 622, all with the appropriate RIL. The mobile data connection for 218 drops in and out at random without any clear pattern. For the other two radios switching on or off 2G only seems to achieve stable connection. However, it does not actually seem to affect whether I get a 3G or 2G signal. The display can say H or G, even when 2G only is checked. Bluetooth did not work correctly with 606.
To top everything off, the GPS does not seem to behave consistently for a all the different radio versions.
I guess that people have different experience with different radios, so which radio are the guys in Norway using? Do I really have to slog through every released radio and spend the day checking each one of them? Can I expect to find a radio/from combination that blacks to give me a stable GPS and mobile data connectivity, as well as good WiFi?
I know this has been discussed numerous times before, but people never seem to reach any conclusions. I'm just looking for advice on how to proceed to fix my problem.
I'm on cm7 .77 and i honestly havent had a blackscreen since i flashed it (yesterday morning) + battery is good now. For me this is the most stable nightly so ill stick with it for 2 weeks on my holiday )
Edit: bb .502 ril 218(i think) dont have any problems with network switching btw

You probably have to, yes. This sounds more like a problem with the specific coverage in your area and how the phone interacts with the cell-towers than an actual problem with the phone. You may be in an area with weak signals from several stations, you may be in an area suffering from sudden bursts of noise, there could be a lot of reasons for why this is happening.
First thing I'd try is to upgrade to the latest official firmware (10C - 0622 for Norway), just to have a baseline for comparison. In theory this firwmare (and baseband) has recently been validated by the norwegian carriers, and should have the best chance of success.
Then you should probably do a manual scan (in phone settings) for networks, and pick one manually.
Also try using the INFO menu (*#*#4636#*#*) and see if choosing a specific protocol helps.
If you're still unable to maintain a stable connection, I'd say that'd be grounds for returning the phone for a replacement.
Weak advice, I know, sometimes there just aren't any quick solutions.

Sort of. In this thread http://forum.xda-developers.com/showthread.php?t=1035041 you'll find complete ROMs of the previous versions. Install one of those with SmartFlash, then run the LG Mobile Update tool to get the latest.

Okay, I see, downloading now. So it is good enough to use one of the smartflash files, I don't have to use nvflash?

No, you don't have to use NVFlash. The advantage of using the smartflash method is that you get a completely "factory fresh" phone, with all the stock content present (movies, music, pre-installed apps) and you're sure to get a matching baseband and ROM.
Note that you have to flash both files, both the baseband and the ROM. The LG update tool won't update if you have a "new" baseband on an old ROM.
::Trym
So the firmwares from that post do not include the baseband? Anyway, I'm currently running baseband 405, so I guess this is sufficient to get the new update. And the new update will then overwrite everything to the latest official version, both ROM and baseband, correct?

Yes, it does. Each firmware pack comes with TWO files, the baseband and the ROM. To make sure you avoid any trouble, just flash them both, though, as you say, you can probably stay on the one you have, as yes, the LG Mobile Update tool will overwrite both the baseband and the ROM with the new versions.

Flashing of old firmware, with subsequent upgrade to latest release for Norway is complete.
I got version V10c, with baseband 1035.21_20110622, kernel 2.6.32.9. My mobile data seems to be enabled as soon as I get mobile coverage (which admittedly is poor right where I live). Even though it pains me, I guess I should leave it as stock for a day or so to see how it behaves.
I guess rooting it shouldn't affect performance in any way?
My initial experience is that it is much more snappy than the stock firmware that the phone came with, but time will show

Yeah, you probably should, as your mission right now is to find out whether you can get a stable mobile data connection or not.

Not to my knowledge, but I'd still advise you to wait a few days while sorting out the connection issue. Not that I think rooting it would affect that one way or another, but if you can't get it work as it is, you can return the phone in the state it is now, factory fresh.

It certainly is. It also *stays* snappy over time, which can't be said for the 10a/b versions.

The first test drive with the new firmware has been completed. On the way out it switched to mobile data flawlessly, but a longer drive it started falling out and reappearing for only short periods. When we stopped at the destination seemed to stabilise with a 3G connection again.
For the return trip I selected use only 2G network. The network connection remained stable for the entire journey.
I will have to test more, but the conclusion seems to be that it has trouble switching between the 2G and 3G networks when moving. I will try the same trip with a Telenor SIM card, and with different combinations of enabling 2G and 3G modes.
By the way, what is the difference between forcing 2G in the regular settings menu and in the special information menu?

The 2G only setting in the phone menu equals the "GSM only" setting in the INFO-menu. I'm far from an expert in these matters, this thread has an overview: http://forum.xda-developers.com/showthread.php?t=675136& of what the different modes do.

More testing seems to indicate that as long as i leave "use 2G only" check, my mobile data connection seems to be pretty stable. It even switches between 2G and 3G, although apparently a bit more conservatively.
I guess I get to keep my phone anyway
Now for some rooting...
Just an update on the results from my testing. The second time I went out my mobile connection never appeared. This was with only 2G checked in the settings menu. In the Info menu, this corresponded to GSM only.
I then changed it to GSM auto (PRL), and then I got my intermittent mobile data again. I then change it to WCDMA preferred, and my data connection seems to be stable for now. This apparently requires much more testing...
F another chapter in the connectivity saga. Having WCDMA preferred selected in the Info menu, things mostly work, although the data connection drops sometimes.
Another problem I'm noticing with the stock ROM is that it usually is unable to reconnect to my home WiFi network when it comes within range. I have the money was selected to reconnect. Sometimes I even find it disabled in the list.
