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.

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.

[Q] ICS and Captivate

Hey
For the past month or so I have been playing around with a few builds of ICS for captivate. I started to notice that whichever build I used whether it was teamhacksung or miui I didn't have 3g. I changed my APN multiple times, tried different radios and it go to the point when my signal in my basement (where I get crap for signal) showed full bars and 3g except the speed was terrible. Is this a common issue? Anyone able to give me a hand?
I just recently went back to my old backup of CM7 and my 3g works flawless.

Since it's not fully developed yet, there can be random bugs like that. Try a factory reset and a full reinstall. If that doesn't work, you may have to try going from stock

Droid 4 and CM10.2 data issue

Is anyone else that's running CM10.2 on Droid 4 having data connection issues? Have you fixed them? If so, how? Does the code need to bake a while longer before data starts working?
I'm running CM 10.22010831-NIGHTLY-maserati
WIFI is working, but I can't get data to work otherwise. I did a factory reset and started fresh. I've tried flashing the ROM and gapps package multiple times. I wiped cache and Dalvik. I tried repairing permissions.
Any Ideas?
Thanks,
Marty

I think i need to update my baseband radio, but I can't find a more recent baseband version for the Droid 4.
I'm currently using CDMA_N_05.11.01P LTEDC_U_09.11.00.
Anyone have a link for a newer version or any idea how to get one?

Do u have the issue on stock rom slot? If so then take it back to stock with the latest utility floating around the forum. Check for system updates if there is one dl and install to make sure u have latest radio if problem persist then it's a Good possibility it's A coverage issue or hardware related problem..

Ok, here's where I'm at now.
I updated my stock rom. baseband is now at 5.25.00. Still won't work on CM10.2.
3g will work on my stock ROM, but not on CM.
I've screwed with the mobile network settings and I can't get any difference in results.
LTE works great with CM10.2, but as soon as I'm in 3g territory, I'm dead in the water. I can receive and place voice calls and I get text messages through the messaging app, but anything that requires an actual data connection, like google voice or the browser, it won't work.
Help!?

updated PRL, still no love.

In some versions i needed to add APN manually, then it would work. In earlier version i had the same problem that 3g would not work. Also problem with reception bars - it would always show like 1 bar or smth like this but would work just fine.

It already has several APNs set up. The one I have selected is: APN: vzwinternet, MCC:311, MNC:480. Most everything else isn't set.

Set adrift without data.
Day 10: I've run out of water. The sea gulls... they mock me... with their wings... and beaks... and of course their raucous calls. They are scheming against me. My only friend is the lone shark that circles me constantly. He's attentive like that. A bit forward though. Keeps trying to kiss me. I tell him "NO KISSES FOR YOU! Not until the second date."
Also, still no data.

First off, thanks for the chuckle
Secondly, you're getting no data at all? Are you on Verizon? If so, do you have LTE in your area? My personal experience has been LTE data is working fine but 3G has been REAL spotty. I did see dhacker on twitter post a new razr build with some 3G tweaks he was testing. So that is being worked on and should filter down to us when it does get figured out.

3G was working fine on 10.1, but is nonexistent on 10.2. It actually acts like it wants to connect to a roaming tower if I switch it to GSM, but it can only see it and won't pass traffic.
I could just go back to 10.1 or run stock, but my pigheadedness, that's a word now, won't allow it.
On the brighter side, I am learning a great deal more about my phone that I had previously known.

The problem seemed to rectify itself around the nightly build on 9-15 or 9-16.

I know I'm a bit late, but I always do the * # * # 4636 # * # * in dialer and I turn off the radio, set the radio to cdma/lte and turn it back on, usually it isn't letting all those other antennas run and it seems to pick 4G LTE faster in my experience.

I think it's a CM10.2 issue...
Hi, my friend with a Galaxy S3 is having the exact same data retention issues we are having on our Droid 4's, which makes me think this is a bug in CM10.2 on various devices more than an issue with our phones. I can get LTE data when I have service, but find that once I loose service, even for a moment, the phone then never re-connects to LTE again and just sits there with white bars instead. Toggling data or airplane mode seems to usually trick it into reconnecting to LTE, but it is becoming annoying to have to constantly check and toggle around to get data back. I've tried every nightly and the M1 and have found the issue remains through the 11/19 build. I've installed the ROM into slot1, I'm not sure if overwriting the stock ROM and using the stock slot with CM10.2 helps matters at all, has anyone had any experience with using CM10.2 in the stock slot instead of Sot 1?

[Q] 10.2 Network and MMS problem

I've been steadily upgrading my GF's phone with Albinoman's builds and they have been working great! However, going to the September 17th build caused a very large drop in network signal strength. She still gets 4g, but its only ever 1 or 2 bars. Mobile data is sporadic at best. Also, the battery drain has been really bad on this build, and I'm assuming it has to do with the signal strength (if its unrelated I'll deal with it separately. Haven't looked at that yet as the signal is the major problem).
The other problem is that she cannot send MMS anymore. I don't know if that is related or not, but if I'd figure I'd toss it out there.
What I've done:
* 2x Reflashed the 9-17 build, and flashed the kernel using ADB. This was a factory restore before the reinstall. (S-On)
* Tried to re-do all of the APN's based on numerous websites that list AT&T APN information. Many of them just caused further problems, so I'm back to defaults (default,supl,mms @ mmsc.mobile.att.net)
* Investigated http://forum.xda-developers.com/showthread.php?t=2348361 (as per the FAQ), but it looks like that is for a different phone entirely so I wanted to get opinions before I looked into flashing a RIL.
I'm open to suggestions at this point, and if people think its important I'm sure I can re-do more of what I've already tried. Thank you all for any suggestions or assistance!

CM 11 Albinoman nightlies 21/01/2014 MMS not working

Hello.
I recently dusted off my Australian Velocity after the Nexus 5 went for a swim at the beach. I have S-off, rooted and installed the albinoman ROM.
There are a couple of issues I have noticed so far.
The 4g connection is patchy at best. Not very stable at all but I can live with that.
The battery indicator is acting strangely it stays in 100% for ages but then it starts going down very quickly until it gets to 14% where it stays for a long time but once it gets past that it just goes to full discharge very fast.
I am having the same issue that many other guys and my MMS capabilities are not working. The phone just stays sending or retrying but messages never leave.
Any suggestions about what to do? I have wiped and reinstalled the ROM a few times and it makes no difference.
On the other hand I love the overclocking capabilities makes the phone feel a bit more responsive.
Thanks and keep up the good work

As for the 4G connection, once you've accumulated 10 posts you should mention this in the CM 11 ROM thread and ask if the APN needs to be any different than normal (or if the mod changes the APN). The battery issue should get fixed if you let it fully charge and fully discharge about 3 times. The MMS capabilities is a known issue; try the specific nightlies that albinoman recommended to fix the MMS issue. New nightlies might break previous fixes and stuff.

Same Issue
I'm having the same issue here for AT&T HTC Vivid, none of my MMS were sent, nor have I received any. It's really essential for me cuz of my group, clubs have MMS and inorder for me to get those notifications I need MMS.
Calls are okay, but there are times where there's no sound on the other caller, so to fix that I end call and call again, which fixes it.
One final issue I've been having since Jellybean and Kitkat is the proximity for when calls, it does not respond. So i have to turn on Settings>Accessibility>Power button to end a call, because the phone's screen stays black during call, and 10-30 seconds after call. Camera is okay too, but doesn;t function well in video recording in apps like Snapchat and Instagram.
Overall, it's a great ROM by albinoman, I wish the Sweep2Wake is soon embedded, that's really great and wayyy better than the power button.

Many thanks, i saw the post!
Yeah I tried clearing everything. Did a manual reinstall of the APNs using a number of different configs.
Did the wipes ....... did a little dance .... pulled the battery and sim ...... sacrificed a small packet of tofu (no goats, i like goats) The gods of mobility have still not smiled my way.
Wont find networks when i do a search yet am nicely connected, can make calls etc etc.
thanks for trying. If i get no joy will reflash a nightlie and see if it resets?!

Yeah, although wiping the caches didn't do the trick, reflashing a nightly (along with wiping data, cache, and dalvik-cache) should take care of the problem. If you are really attached to your app settings, look into titanium backup for backing up your apps along with their data; it's also the way I save my WiFi passwords.

I installed xposed and Intelli3g and with a bit of mucking around now have 4g back!
Seems to work, have 4g 4 bars!
My initial attempts to force lte caused me to have no coverage (I was at work in North SYd so good LTE normally).
Using the "use all" option in Intelli3g, a reboot and swapping around towers was the trick for me.
Thanks again
