[G2 Q&A, Help & Troubleshooting] pquitonegro:
PLEASE let me explain and read me, and forgive me for my bad english writting. I'm a noob on this theme.

I have a LG G2 D802 32gb, running Stock Kitkat 4.4.2 on version "D80220d-466-92".

I installed Lollipop and got back to Kitkat many times by using Flashtool. Also, I rooted and installed TWRP with AutoRec in Kitkat a lot of times, I installed Custom ROMS, I changed Bootloader and Kernel (Dorimanx), and once I had a problem with storage, I installed by mistake a 16gb Stock KK version in my 32gb, but I fixed it.

Last week I installed Mokee ROM with TWRP, I made the Wipes (Selected all options: Dalvik Cache, System, Data, Internal Storage, Cache. Because I use USB OTG), I changed bootloader with Nevax BootloaderChanger(Lollipop Bumb), I installed the GAPPS. And it worked fine. BUT, when I tried to go back to KK Stock, Flashtool didn't work, like it didn't recognize my phone (my PC did recognize the phone, I have right installed LG Drivers). I had to converted the KDZ KK File to Zip, and flashed it with TWRP, that was the only way to go back to stock.

It seemed to work fine, but I tried re-installing KK Stock in Flashtool, and this time it worked. When I went to storage it showed just 10gb avaible, and when I got in hardware info it showed 32gb memory. And I tried fixing storage again, and it worked.

The problem came here, I noticed when I get in Download Mode, it says ROOTED in red letters. And the past times I got back to Stock these letters didn't appear. Then I didn't do anything.

I started the phone normaly, but when I tried installing Towelroot and WifiKillPro, the device didn't install them, it said "Application not installed". I could install APK's and AutoRec, Quickboot and Rootchecker normaly. Then I decided to Root the phone with ioroot25 and it worked, I used Rootchecker and all was fine.

BUT when I installed AutoRec again (I gave SuperSU permissions), and hit YES to install TWRP it just said "checking for loki...installing" and a few minutes past, I closed the App and re-opened it, but this time it said:

"error: Tried to install loki_tool, no luck, please try manually installing loki_tool, app will exit".

I chose to install it with PC (recovery.bat), but it says:

Reboot into recovery now [y/n]?

-----------------------------------------------------------------------

I used Flashtool again and again, and the red letters (ROOTED) didn't disappear.

I never had problems with this version of Kitkat, I could rooted it and install TWRP AutoRec normaly.

I made a Wipe/Factory Reset, and I rooted with ioroot25.

I WANT TO KNOW IF MY PHONE HAS A PROBLEM.

It is working fine, but the things I told you don't let me in peace.

NOTE:

I fixed storage, with the Total Commander and Minimal ADB and Fastboot method.
