Charger problems (on KK baseband) - G2 Q&A, Help & Troubleshooting

hi,
whenever my phone is running any rom based on KK modem/baseband, when i charge it i can't use the touchscreen.
but i noticed something - if my phone is running a rom that is based on JB modem (CM11/12, RR...) my touchscreen works great when it's charging.
that's a weird problem i know... but i would be glad if someone will help me to solve it. also seems to happen on kk stock but not on jb stock.
(LS980 - Sprint's variant)

[Q] Signal/connection lost on wakeup [Solved]

Hi all,
Since a couple of weeks i'm suffering from the following problem.
On newer roms the signal to my provider is lost upon waking up the phone (from standby/screen off).
A couple of things happened, i switched providers (from T-Mobile to Ziggo), i flashed a wrong modem which caused sound problems (from the omega rom 13.1). Since that moment i've had this problem. I'm not sure if its related to what happened, but that's what i know changed.
I've tried several modem files, though the modem version MI1 which works properly with Echoe v3, gives the same problems on Echoe v6, Omega 13.2 and Phoenix v5. Updating to XXUEMJ7 makes no difference at this point. I'm not quite sure whether its the modem at all due to this, but it seems the most obvious thing to look at when facing connection problems.
When the connection is active its working properly, i have data, i can call, receive SMS messages and everything. But press the off button once to lock the device, press it again to unlock it, and i see the signal status icon change to no connection.
At the moment with Omega 13.2 installed, its reconnecting quickly after i unlock my phone (something that didnt happen on the other roms), but it seems like very weird behavior. I've googled and searched the forums here for people with similar problems, but they've either not been documented yet, or i've been using the wrong keywords to find it.
Does anyone know what's going on, and how i can fix this?
Many thanks,
Amber

Hello,
Do not use roms based on mj7, use roms based on mj5 or go back to 4.2.2
I have tested all radios many kerneles with many mj7 based roms and always had this problem.
And use radio mj5 with mj5 roms likeecho illusion bobcat, visxii.
Get radio from here:

[Q] Anyone here running AOSP 4.4.2 on MK6 baseband? Signal issues?

Hi all. Long time listener..first time caller.
I have an i337m Canadian S4 variant, running AOSB v.1.3.1 (CM11 based), with the latest OTA modem available at the moment to us unfortunate - left holding our jellybeans - Canadians, which is MK6. My issue on this rom has been battery drain, although the rom is quite stable, and I'm wondering if the 4.3 modem could be the culprit (or at least one of them). Battery stats shows Cell Standby is using about 20 percent of battery on LTE, and I never get more than two signal bars with LTE enabled. Anyone else with similar findings? Does this sound like it could be fixed with a modem upgrade once one arrives?

Find the mk6 modem odin file (modem.bin) and flash in odin.... check my screenshot... installed 4.4.2 (Danvh's rom) then flashed modem. I was on mk6 but was having connection issues also....

Hey thanks for the quick response. I'll definitely do that when I get home and report back with results. I didn't know that the modem could become corrupted after a rom flash, so I'm hoping this fixes it. Do you happen to know if this is a fairly common problem?

There have been quite a few complaints about data across most 4.4.2 roms, unitl we get the matching modem, MK6 is the best we can do. I know my data did improve flashing MK6 after flashing the rom even though I was already on MK6....
So I flashed the MK6 modem again yesterday - twice, to be sure - and honestly it's about the same. Not seeing any real difference at all, so I'm thinking this is probably as good as it gets until the new OTA gets pushed. Thx Gage for ur help on this

[Q] lost wifi after flash, please help

Hi, I've had my Note II LTE for about 16 months. I found it very unstable on the stock 4.1 android it came with and eventually figured out how to flash it and went with the Slim Bean mod I found here, which has been pretty good. However with the latest build of Slim Bean 4.4.2 build 5, the volume was far too low in calls, so I decided to try the stock 4.4.2 rom [ROM] Official Stock Samsung KitKat 4.4.2 rooted & deknoxed
However although it flashed fine, my wifi now won't turn on on the phone, everything else seems to work, but the loss of wifi is a catastrophe.
Furthermore it seems to have unrooted the phone so I can't use RomManager anymore to flash any other rom.
At the moment I'm stuck, I can't seem to flash any Rom as RomManager won't work, I cant boot into recovery (no option) and the Rooting method I orginally used no longer seems to work with this 4.4.2 official Samsung stock build.
Can anyone help me? Either to fix the wifi, or to get a working rom flashed?
Thank you

well by fixed it, I mean I managed to flash a different working rom to it, not that I managed to get the wifi working with the rom I mentioned above.

[Q] Switched back to touchwiz from cyanogenmod - radios arent working - advice?

Hi all,
I've switched back to Touchwiz for the camera after having cyanogenmod on the phone.
Now it seems like a catastrophe - WIFI won't work with some roms (specifically touchwiz, and now touchwiz wont even boot) while making and receiving calls and texts won't work with lolipop or with cyanogenmod.
I've wiped totally in recovery before installing anything to ensure no issues, but I am at my wits end, about to buy an iPhone tomorrow because I need a reliable phone for business.
Any advice on what I might do? I have the I337M version (rogers)

If all else fails, Odin back to stock.
Give the lollipop Google play edition rom a try, it's been rock solid for me and many others. I will say that for whatever reason, I was never able to get WiFi working in the hyperdrive rom (since rls19) I tried changing modems and what not, but switching to a different rom worked workout issue. Try golden eye rom or one of the others from iB.

Which lolipop rom do you use, might you have a link? L is gorgeous
Will try other ROMS. I've attempted to ODIN back to 4.2.2 but wifi is not working even with clean wipe.

With the stock kernel you will ever have reboots. The only kernels without reboots are the two you mentioned.
