JK3 modem, loss of all reception, drains battery, requires a reboot

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.

anyone having this issue or have any ideas?
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.

this continued the same way on perception7 with cogkernel2. no real difference.

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.

I'm using the non oc. I'm not gaming or doing anything too wild with my phone so non is just fine for me.

hmmm, makes me think that's the issue then. most of these roms have kernels that have the oc feature.

hey keener, did you have the oc version of cog?

[Q] Sudden loss of data connection?

I am quite baffled by this but it seems that my data connection is just gone somehow, I was watching TV and i looked and my little "H" symbol wasn't at the top nor an "E" and all i have is bars. My sister's phone (non-smartphone) has 3g still though. Could this be due to me doing something or should i just try flashing back to stock?
EDIT: I found out my problem, I guess I pressed data network mode by accident in the extended power menu.

If you have wifi you can flash a different modem

no access to wifi right now :|

If you have a pc you can mount to you can dl modern to pc then transfer

Do you think a new modem would really fix it though? I've been using this ROM for more than a month now and this has never happened before.

Did you call at&t to see if there are issues in your area?
Who knows if modern change will work, worth a shot

haven't called at&t yet, i'll try that.

Okay i got a hold of at&t and they told me there aren't any data outages in my area.

Normally I would say make sure your apn settings are right but if it was working and now it is not that does not make sense have you tried moving location

Hmmm, well the new modem didn't solve my problem. That sort of disappointed me, haha. But I really dont want to flash stock and the problem persist and feel like i wasted time and have to restore everything, even though i would most likely flash a new ROM which i kind of want to do anyways.

[Q] When I turn wifi off, Note does not connect to 3G or HSDPA

Hi guys,
I have this strange problem, it even seems random.
After I turn wifi off, my Note does not connect to 3g anymore.
And I have to reboot the phone to get it working again.
Does anyone experience the same problem, or knows a sollution?
I rooted KK1 and flashed LA4 using Mobile Odin.
Cheers,
Daan

I've had this problem once, but it worked again after a reboot. Haven't experienced it again. It happened on KK5, but i flashed LA4 yesterday, so it's too early to tell if it will happen again.
It also happened on my Desire HD with MIUI and also while running CM7, so it might turn out to be a bug in Android.

I guess you had turned/switched off data network mode by pressing and holding the turn off button for two seconds.
Try and turn it off and see if it is the same symptom that you had before.

No, this is not the issue.

I manually set the APN settings for Telfort, removing MMS and setting it up for "internet" only.
Did a wifi on/off cycle, with a short interval and it seems to work.
Going to test with a longer interval. Not completely convinced yet.
Hope it's fixed.
---------------
edit: Not fixed!
On wifi for half an hour, turned it off and [email protected]#$% 3g does not connect anymore.
Maybe it's just Telfort. They don't have the Note listed on their website, but still.

My infuse 4g does this. I have to put it in airplane mode then back to get my data to reconnect. It did this stock and on serindipity 7. I couldn't find a fix either.

Annoying stuff! Cycling airplane mode does not work for me, only a full reboot.
But if you had the problem too, It could be that it's the network's (in my case Telfort's) problem.
Maybe I have to get my sim replaced, but I'm switching to T-Mobile in about a month.
So it's a bit of a pain.

I am currently using the infuse on o2 in Germany, but it did it on att in the states also. I can't wait to get my note. I am just waiting for it to be released on o2 over here. They have the black but I really want a white one.

Telfort used to be O2, it has been using KPN's network for a while now.
So it's probably not connected. Though it is a strange coincidence.
I'm off today, I think I'll walk by the Telfort store to ask for a new sim or something.
Maybe they'll have to flip a switch somewhere.

Yeah you're right, I have to troubleshoot properly. But it's such a pain
And I think I recall having this problem a few roms back as well.
I'm not sure because I was on wifi all the time.
But I have to wipe, I'll use titanium backup so it won't be such a hard blow
Man I'm going to pissed if it turns out to be the network

Thats a pain i was so tired of formating,..reformatting....coz many custom firmware have some error and new updates keep coming almost daily...and all ask to wipe for best experience..dat was when i finally decided to come bk to stock and stick to it...
yeah it doesnt hav those fancy colors and throbbing speed which a custom rom boosts about but...but hey everythin works flawlessly and i dnt have any tension of random reboots and alarm not ringing..or any smartphone related error to comeup...plus all my apps and schedule is there forever no reinstalling tension....enjoying my phone....

Okay, so I I did a full wipe and installed a deodexed rooted LA4.
I still have this issue.
Also tested on KK1 stock and still experienced this issue.
If it does this on KK1 and LA4 it's reason enough for me to believe it's the network.
I'll just wait for my T-Mobile plan to start. Meh.
edit: It seems to work just fine on CM9 :-/

[Q] My IncS completely disconnects, often!

First of all, let me start of what I've tried doing, in order.
New SIM-card, factory reset, unlock + root, custom ICS (VirtousQuattro).
None of the above solved my problem, it still persists! The problem is, the phone disconnects completely from the network (no bars) and I can't manually search for a new provider due "active package transmission" or something like that, it stays disconnected for 1-3 minutes and then reconnects. It happens fairly often, like once for every 5 times I try using the phone. I haven't noticed the problem when being connected to a WiFi, so I'd assume the problem is related to an issue between the phone and the network.
Has anybody else had this problem? Any idea how to solve it?

Have you tried flashing a new Radio? I can't see how that would differ from flashing a custom ROM, but might be worth a shot?

Yes Naforcee, I have exactly the same problem. And it never happens while using wifi as you said.
It started immediately after I updated to Sense 3 / Android 2.3.5 from HTC.

What was the version of Android in your previous Rom? I had issues when I was on Froyo and went to Gingerbread without flashing a new radio.

Don't think it's a physical problem, I have perfect connection and it just dies out for about 2 min until it reconnects, and I can't search for network when it's down due to active packet transfer..

Could try a new SIM card. Might not fix it, but worth a shot - I've seen this posted as a fix for other people.
I used to have this problem on certain radios on the Desire Z, after flashing around a bunch of radios to try all of them. Stuck with one and it went away, so it was software for me.

Try flashing this radio http://forum.xda-developers.com/showthread.php?t=1471861 using the ADB method. If that doesn't help I recommend doing a full wipe and reinstalling the ROM. There are a lot of different custom ROMs for IncS which can be found at http://forum.xda-developers.com/showthread.php?t=1136463
I personally like Niks ROM and Android Revolution HD.

Looks like rom installation issue.

My son's Inc-S having a similar problem to the OP, but more severe. A couple of weeks ago he entered airplane mode with all behaving normally, but since exiting airplane mode at the end of the flight he hasn't been able to register on the network (voice or data). We've tried:
fiddling with all the network settings
change sims (all sims work on my Inc2, none work on his IncS)
cleaning the antenna connections
reboot
factory reset
flashing new ROM (Android Revolution HD 2.3.0)
flashing new radio (3805.10.03.29_M)
So far, no satisfaction. We're still seeing no bars of reception (with an X) in the notification area, and don't have the option to manually or automatically register with any network operator (although several occasionally show up as options under "Search Networks"). We usually get the error message, "Unable to search for network while packet connection is active" when trying to select a network. Funny thing is, mobile network data has been shut off on his phone for the past month so the packet connection is definitely not active (wifi is on). Based on a network signal analyzer app, the phone is receiving the same mobile network signal as mine (-65 to -70 db) when they are side-by-side, so the problem does not appear to be in the antenna. The phone works just fine using wifi but is useless as a phone.
Any ideas about what to try next?

Probably a RIL-Radio communication issue. Recommended radio is the newer 3822.01.08.14_M radio, so maybe you should try that.

Your model is a d400, d400h or d400hn?. I have the same problem with the wifi

If going back to stock it is still the same after a factory reset (deletes all data, backup first) and with different routes then it's a hardware issue, no matter what model you have.

My problem was an update and restore the last version lol
