Questions on ROM development

I am able to extract System.img from the 4.4.4 ODEN install and mount it in Ubunto. I can modify the folders and files to remove bloat, etc. I am able to repack back and use FlashFire to flash the 4.4.4 modified firmware.

My question is related to 5.0. I have tried the same method and after several modifled attempts, was able to extract and mount the System.img. After debloating, etc. I tried to repack it the same way but in FlashFire, it fails the MD5 check.

I tried another approach. Instead of repacking the full firmware package, I just created the System.img as a stand alone flash-able package. I then install 5.0 through ODEN, install Root and FlashFire.

When I try to flash my modified System.img through FlashFire, it passes the MD5 and installs successfully but it never boots. It never even makes it to the initial boot screen.

After that, I have to ODEN back again and start over. Any dev's out there that might know what I might be missing or can point me to some documentation on the process for 5.0?

AirPlane Mode - keep BT and WiFi on

Hi.

//some info :
Samsung Galaxy Note 4
Beanstalk 6.12 (based on CM, android 6.0.1)
Xposed enabled, rooted etc.

Coverage in my school is pretty bad - low to no signal. Too much concrete I guess. Because of it my battery drops pretty fast even when I'm not using my phone.

I made a tasker profile to enable the airplane mode when there's no signal. Task detect if BT/WiFi was enabled before and turns it on again. Task disables Airplane mode after 20 mins to check for signal, and whole task restart.

However the problem is that BT is disconnected for a while, which is anoying and disables smart lock (up to first unlock), disconnect BT headphones and watch. Tweak is worth it ; now battery drops much slower. I want it to keep checking every 20 mins because there are some places where signal is pretty good.

//the question
I'm looking for a way to tweak airplane mode (or just disable signal with other method), and leave BT/WiFi untouched.

So far I found this :

I guess it's for older android versions, but tried anyway. In this folder I have almost right file. It's called "settings.db-journal". SQLite editor can't open it and build in editor shows Chinese? letters?.

If you could help me that would be awesome.

Thanks,
Peter.

Can't use or uninstall Titanium Backup

I've used Titanium Backup successfully on various phones, including my One Plus Two.

But last night I noticed that when I made a backup any app, it looked like all was working, but no backup was made (and no error message).

So I decided to re-install the app. But when I try to uninstall it, the phone immediately reboots. I've never had this problem with any app before, so I'm wondering if anyone can help me resolve it.

SM-G900F or SM-G900P

Ok so I bought a new samsung s5 I checked everything and I'm pretty sure it's original.
So, I was about to root it when I got into download mode and realized it said the device model was SM-G900P but the thing is in the about device menu it says it's 900F. I took out the battery and checked and it says it's a 900F.
Therefore I'm confused. I don't know what to do since I don't wanna brick it. I would really appreciate some help. Thanks in advance
