Phone not charging like it used to after latest updates.

My phone is at "OG7" and now when I plugin my IQ anker car charger, the phone display a message that I should use the changer that came with it. Didn't see this with the older OS. Also it doesn't charge as fast as it used to with the IQ anker charger.

So did samsung or version set the phone not to charge faster with non smaung chargers?

Any thoughts?

Buying used Galaxy S4. Which softwares are "rootable"?

I was about to start a new thread asking my question, but don't like to do that until I check to see if it's been answered already. The problem with this is I'm not even confident I know the correct terms to perform a valid search.
So, here is my question: I'm planning to buy a used Samsung Galaxy S4 (AT&T) and I want to root it. Are there "versions" on this phone that are "rootable" and "non-rootable"? Which versions are which and what do I ask the seller to identify the version- the baseband version?
Can anyone tell me if this question has been answered already and if not, where should I post the above questions?
Thanks!

unpackimg Compression used: data Error!

Hello Comunity:)

I want to play around with my own build of Cyanogenmod. I have an not yet supported (Mediatek) device and want to give it a try... (It probably will not work and I will hardbrick my device but thats better than just throw it away and buy a new smartphone because mine is quite old).

I have the stock ROM already with the boot.img and recovery.img and a Windows version of Android Kitchen which contains unpackimg.

Now I tried to unpack an image (I tried both boot.img and recovery.img) but it gives an error:

Code:

Then I read about "lokied" images, which seem to be protected somehow. Because of that I downloaded the Loki-Addon and tried unlokimg. That gives me a new image which results in the same error as above.

Sorry, but for some reason I am not allowed to add links to this post, maybe because I am a new user...
But the program I used could be found in [DEV][TOOL] Android Image Kitchen - Unpack/Repack Kernel Ramdisk [Win/Android/Linux] by osm0sis.

Is this a common error and is there any way to use those images for building my own Cyanogenmod?
