[Q] <DC CONNECT> IO error: msg='/127.0.01:7771 - Connection refused

In the new OTA leaked ROM base, v3.28.651.6, this seems to be happening to many people, including myself.
<DC CONNECT> IO error: msg='/127.0.01:7771 - Connection refused
This happens after turing 4G on and then turning it off. You can see this error in logcat. and it repeats endlessly!
Does anyone know why or have a solution to this?
It has also been reported HERE.
4G works fine, it doesn't break 4G, it's just some stupid looping error.

its not just the new rom, it happened on 2.1 and 2.2 ota's.

It has been concluded that this is normal behavior, since the early builds. Apparently, that's how wimax works on the evo

That's pretty lame coding on HTC's part then. Why have something that is turned of try to reconnect infinitely to something. That has to waste resources.

It happened to me yesterday but when I rebooted I could connect and stay on 4g. Weird.

In regards to the effect of this on battery life

9pm - 4g Turned on, then off.
9-~12: screen always on, multiple reboots (4g turned on/off after each reboot)
~12pm - screen off the rest of the night (while in the error state)
The results to me look like any other day under the same usage conditions. To me, at most this is an annoyance when trying to logcat for something unrelated, but doesn't seem to affect battery like people have been posting in multiple forums.

I agree, I am at work for 14 hours a day and I come home with 35-40% battery left. Prior to this new leaked OTA ROM base, I came home with 5-10%. I use the same phone the same way, so regardless of this weird arror, battery life is still good.

Like the guy in the post that you linked to on the Sprint forum says, seems to go away if you Turn off 4G and then completely power down (Hold power button, and choose Power Off). A reboot doesn't fix it, has to be complete power down.

Agreed, it's a silly leftover, I usually just use some sort of a tail-like application, and just filter those out if i need to do logcat.
It's the 4G radio that causes major battery drain, not the repeated log messages anyway

My Infinity is failing to go to sleep, and instead overheating

I have had a tablet overheat since I had the Transformer Prime which after a few updates for ICS from ASUS the tablet started overheating when I thought it was sleep.
Now I'm seeing this symptom return with Jelly Bean on the TF700T. Is anyone else having this problem?

If it's happening like that it is most likely an issue with an application you have installed. Check to see what's using the most power in the power section or install something to see what's keeping the device awake.
Mines been solid since jb and have had no overheating or sleep issues.

Google maps does that, turn of gps and location service....i think its the last update of google maps.
and because i dont use that software, i "delete" the app

I've had the same problem and posted in the Q&A section but I didn't know which app. I'm going to uninstall maps (or at least all updates) just to make sure.

I'm certain it's not an app but the OS. My Infinity wasn't overheating until it got JB.
It worked fine in ICS with the same software that I migrated over from when I had a TFP.
It did it again today, it was getting low on battery with only 50% left on the tablet and the dock completely depleted which I was going to recharge, I turn my had and look back and noticed it self-rebooted, but right after the ASUS logo it went to a black screen and it's just stuck like this until I can scramble around and find something that will fit into it's tiny little reset hole.

I'm also having this problem. Turning off gps didnt help but toggling the wifi was effective. Ive had it on for 1 day and 6 hours and still have 95% with relatively little use. The biggest battery draw was tablet idle.

Mine's done this a few times since JB, too. Never before.
You can hold down all three hard buttons to force a reboot. Hold them for about 10 seconds and you'll feel a quick vibe.

If its ok with wifi off sounds like the tablet might be trying to access the network
As you can see mine has wifi on all the time and its been 15 hours

The particular problem with mine is google maps forcing the wifi on when its supposed to be sleeping. When I manually toggle wifi off it behaves correctly.

Is there a way to fix GPS lock on Jelly Bean ?

Hi,
My GPS used to be locked within a second on stock ICS.
Now, I'm on Sky Jelly Bean, and I notice that it takes a long time to have GPS locked, and its accuracy is far from what we consider 'accurate'.
So is there a way to fix these GPS issues on Jelly Bean?
Thank you.

Install the AGPS patch in the dev section. It's never failed for me on any ROM I've used it on.

I just installed [Rom]Sky-JellyBean-4.1.2) Update 10.3 ((Base T10-(10/26/12)) GS3-Touchwiz--Vs--CM 10, and GPS wasnt locking either.

I downloaded the Google Specific 3.1 below, and GPS immediately locked:

Hope it works for you too.

Actually, I spoke too soon. It looks like the patch was working since it immediately locked on. I went out for a drive and used the NAV, and initially it was working, but after a few minutes it began to drop out and report "GPS Signal Lost"...
From your screenshot, it looks like you can see at least 12 satellites with fairly decent signal.
I am using a different app, and mine seem to vary between 0, 2, 5, and 7... Constantly changing. Wish mine looked like yours.
I've already wiped everything, and going back to stock using both Kies and Odin methods, but still have the same issue.
Read somewhere to wipe the external SD and eemc, so going to try that now.
Hopefully its not the phone.
What app is that screenshot from? Want to try it.
Thanks!

It's called "GPS Test". Pretty simple app.

NFC Service gobbling up battery like CRAZY!!

Hey guys. Im on Xenon HD 3.0 (4.2.1) with Marmite Kernel 7.3. I have used many 4.2.1 ROMs but all of them have this issue that the process "NFC Service" takes up too much battery. It was there on JellyShot, Xenon HD 2.0 and SlimBean (all 4.2.1 ROMs). However it wasn't there in CM 10. My device model is i9020.
I've attached the screenshots of the battery stats. Hope someone can fix this issue. As the battery life is the Biggest problem here and I haven't seen anyone else with this similar case. Thank you

untick nfs on settings

Just noticed. I have an NFC bug. My NFC is continuously on :/ i cant change it back to OFF. Here's the Screenshot.

I'd this problem and i just delete or say just uninstalled nfc service..
No NFC battery drain here..
and i don't need NFC, if you need it and want to stop it just freeze it or disable it or you can turn off nexus s, pull out battery, press power button for few seconds, then reinsert battery and go to setting and you will be able to untick NFC setting..

What I tried:
1. Reflashed the ROM I'm on... Just the ROM and GApps. No kernel no nothing.. Still had the problem.
2. Tried freezing the app. No luck.
3. Uninstalling "NFC Service" didn't do anything either.
No luck :/ still the NFC Service is ticking on :/
Had anyone else successfully fixed this issue? Im getting it on all 4.2.1 builds :/

"NFC Service" still running... :/ even after a restart.. I'd let it settle down for a bit :/ is there a solution that makes the faulty NFC Service thing OK again? :/

Had the same problem for a day. Was freaking out. I think I used android beam or wallet. Went away after a battery cycle.

What i did after Flashing Rom is, uninstall NFC.apk and TAG.apk from system->app and then reboot.
Now i don't have NFC settings and Battery drain is gone as well..

NFC.apk can't be removed from KitKat
Uninstalling the nfc.apk did the trick for ROMs up to CM 10.2. But in KitKat based ROMs it is no longer a solution. Once you delete the apk or restrict permission, the Settings will FC when opened. Is there any other solutions?

blank screen

hey guys,
any of you had an issue with the screen going blank and never coming back on until the watch is rebooted? ( I have ambient screen on)
everything is still functioning, phone detects it as connected, i get vibration for notifications and can even get screenshots from the watch using the android wear app.
using stock watchfaces, not installed anything yet, only setup android pay, since i only intend to use for notifications and android pay.
this is really frustrating, it's happened 4 times within the first 24 hours...

if you can't touch and wake the device, you may need to send it for RMA. Do not waste time in testing, even it is a software issue. Let them fix it for you or simply replace it.

thanks, yeah that's what I was thinking too. just wondering if this was a common issue.
I'm based in hk too lol, just past the 7 day direct exchange period so i guess i'll just have to wait for a repair.

It is acceptable if the watch is loaded with many software. But not normal if it is freshly setup. You may try the official rom here and see if it is okay.

I have this problem now.
Screen sometimes starts working at random for a short while but goes back to blurry.

Mine also goes blank occasionally and only reboot helps, but it's so random, and maybe once a week? so I won't even bother sending for warranty because they might send it back saying that it's not happening to them.
Yesterday it happened while I was tracking my workout so that's a bummer but happily I was able to continue after reboot.
p.s.
I'm using always on display.
