Kindle fire 2 massive battery drain "cell standby" - Kindle Fire 2 Q&A, Help and Troubleshooting

Yesterday i installed battery stats to see why my kf2 was loosing around 25% of the battery at night...
I found this:

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
I was searching and found that some galaxy s3 users experience the same issue, they flashed a .zip file to fix it...
Should i flash that file or there is another method for the kf2???

no way, don't flash any zip that is not made for your device!!! And make a nandroid backup before modding anything

Just turn data off

Looks like with a simple reboot it got fixed, but i also put it on airplane mode just in case it happened again

There is an option, somewhere in the settings, to disable data. I don't remember where offhand, but I know it's there.

NFC issues with 4.2.1

I just noticed that my NFC is not working, and I can't turn it on. Does anyone else have this problem?
I know it was working just fine on 4.2.

Tried a reboot?
And are you sure you're using a battery that supports NFC?
You could also try reinstalling the firmware as a last resort.

I tried reboot, clearing out caches, fixing permissions, and even wiping battery data.
I did get a spare battery just recently, but both of them are stock Samsung batteries that came with the phone. Also, it doesn't matter what battery I use.
Why dont you flash some other ROM/kernel to see is it a software or hardware issue?
i dont have any issues with NFC...i use it daily with NFC chips.
unfortunately i have heard of this problem before (as well as not being able to turn on bluetooth) and the only fix was a factory reset or a flashing the stock image.
I am running rooted stock ROM.
Now it also drains my battery

Tried couple of times, no luck.
In order to stop drain, I deleted nfc app from system folder, and it looks like it helped.

[Q\Help] no data on CM12 unofficial ls990

Okay so It was requested I post here over the actual thread for this help.
So I installed CM12 for the ls990 and it's showing I have LTE but it ask me to sign in. When I go to the notification it says networks blocked. I can't make calls, I can't do text or anything. I figured this was a bug with the rom but nobody's else looks to be having this issue . Any idea,what I should do ?

Hmm. Did you restore to a backup and see if everything was functional? (In terms of cellular connection.)

I deleted it by mistake and I'm going to install a stock based ROM instead

Nexus 5x sensors unavailable

Hey guys!
I recently purchased a 5x off of ebay for $200 and have been largely happy with it. Unfortunately, I've been noticing little annoyances, like not turning off the screen when I put my phone to my face. Not noticing when I pick up the phone, and not noticing when I try to rotate the screen into landscape mode.
I found some other users talking about re calibrating their accelerometers, but I think my issue may be a bit broader.
Testing with apps seems unresponsive on many levels. Using "sensor readout" app all sensors seem to have the same fate shown below. "Waiting for sensor to become available"

I don't know what that means
Edit: Newest n2g47w vendor image installed Still no sensors available
This vendor fits to Android 7.1.2 revision 12 and higher.
Still not working
Well, I just performed a "flash-all" with Google's most recent bullhead release
bullhead-n2g47w-factory-e4179e51
I am still getting "possible malfunction" in the app GPS status and toolbox.
I fixed it! I had installed the
H791-32GB-MDA89E TOT file, and repaired the sensors
Fine

Question Can't update at all?!

Hi there
I'm on 3.15 and I was prompted with a new update (weird already as when it prompted it said 3.15 again instead of 3.18 or 3.20). I tried to click download and install but after 5 seconds of not going past 0% it would just go back to the same "Download and update" button. I even got the download on my notification bar still showing 0%...
So I decided to check how to do it manually (yes I backed up everything already) but realized the three dots aren't even here to try to flash it?
Any suggestions on how I am supposed to flash the new version?

Easy
First download the Activity Launcher
Search for "System-Update" click on it and then "Local-Update" then you can manualy update your phone

I did that, (didn't need to download as was already installed) it opened exactly the same thing as in the screenshots and behaved the same way.
Edit: Nevermind I think I found it. Just searched for "local update".

So far so good, battery drain is definitely slower compared to stock
