[Q] Only 10GB available after recovery ?

Hi ! .. So I just got my LG G2 yesterday, and today I tried a few different things wich ended in me having to use the LG Mobile Support Tool to "force" an firmware update (stock), and after the rollback were done. I only had the possibility to use 10GB of my 32GB storage.
Anyone have any idea why?
It says that I have a total of 10GB storage when I connect the phone to the computer. And I have no idea why or what to do.
I havent encountered this issue before at all, and I feel that I'm somewhat decent when it comes to installing firmwares on phones. Regardless of brand.
And it does say that the model is the 32GB when I check the hardware-info on the android itself.
Maybe this has something to do with me using the adbcommand for mounting storage incorrectly?
I thought however it would be reset when I used the LG Mobile Support Tool to hardreset everything though.
Anyone got any tips on the matter?
Edit:
Just noticed this guy got the exact same problem;

[Q] Strange touch behaviour after Stock Rom flash and root befor

Hi there,
I realy need your help on my problems with the G2 32GB D802.
I bought it on ebay and instead of getting it from GB it came from HongKong and I didn't think about it that it does not have a european ROM.
First I wanted to root and flash custom recovery and cloudyG3 rom. After rooting with ioroot and installing the TWRP I stuck in the fastboot mode. First problem I did not make a backup because I never reached TWRP. Download mode only appeared for a second an then disappeared again.
After a lot of searching I found that probably the 802autorec.apk was wrong, since I don't have a european model. So I installed via fastboot a laf.img for a D800. After that the download mode was working again and I installed different roms via flashtool2014. The installation worked again but after rebooting the phone I had a lot of trouble with it. That the reason for trying different roms as I sad befor.
First, the fingertip points at different areas of the screen but not there where you are touching the screen. So you can not reach the buttons or write on the keyboard.
Second, after connection to pc I recognized that my 32GB model had only 10GB internal memory.
Finaly I can not use the phone. For me it seems that I burned my partitions and need your help to get it right again.
Please give me a chance.
Best regards an thanks for helping me.
p.s.: I tried to go to the settings menu in the phone and reached it after a lot of confusing taps on the screen. All the phones informations like IMEI and all the other disappeared. Something realy went wrong with it.
No one an idea how to get back to normal?

I now have the answer from the dealer that my G2 has the Firmware D80220B.
Just try and test it. Good luck.
@Angryyolk
I just ask myself how to enter engeniering mode?
Thanks for your help.
I walked one step forward now.
But there is still no solution for my problem. I found a link to LG "http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI" to get the information about the version of my stock ROM. Just replace IMEI by your real number and you will get it.
In the meantime I flashed the rom with flashtool but the screen behaviour is still the same.
I later rooted the phone with towleroot and then installed the correct autorek.apk for the D802. That worked properly. I reached TWRP but in fact of the weired screen behaviour I couldnt do something. I tried to fix my IMEI problem with QPST but this tool showed only empty tables on my PC when I connected my G2 with usb.
I tried an update of the screen firmware as posted above. The code that has to be entered on the dialer is 3845#*802# but it wont work for me since I can't enter "settings" the service menu. That's because of the weired behaviour.
Beste regards
I now was able to enter the hidden menu. And I was able to get to the menu point "update touch firmware" but nothing happend.

Upgraded from 4.2.2 to 5.0.1 via LG Mobile support tool, sudden loss of storage space

Hello, i decided today i wanted to go from 4.2.2 to 5.0.2 (mistype in title) on my D802 LG G2. Phone running stock with root but read up on it and people (xda for example) said the only thing that would happen was a loss of root, which didn't bother me that much. Fast forward to update completed and now the majority of my memory space on my 32GB LG G2 is gone. Going in to Settings > Storage it shows "Total space 32GB", and "Available 6.69GB". Looking further into it, going in to "Misc", there "System Data" taking up 21.86GB, which seems way more than it would have too.
I upgraded via the LG Mobile Support Tool from here: http://www.lg.com/uk/support-mobile/lg-D802 and everything is working, expect the storage space issue.
Connecting the phone to my computer it says internal storage is 10.6GB, which leads me to believe somehow i've gotten the 16GB firmware, question is how since i upgraded via the LG Tool? The only weird thing is that the phone says in settings that total storage is 32GB.
So what is there to do now?

Something went wrong with the LG update, used this guide: http://forum.xda-developers.com/showpost.php?p=50790181&postcount=49 and all is working well now.

LG G2 display problem after going back to stock

a few feeks ago bought a second hand lg g2 d802 running kitkat 4.4.2 wich was only detecting 2g when i try to connect to the internet, i tried to solve this problem by entering the hidden menu and selecting the network types it could detect but no luck, so i decided to upgrade to lollipop, i downloaded the lg support tool and went for it, when the update was done i found myself with an almost completly functioning device except it had the "imei=null" problem, meaning no network at all --"
i tried the QPST but it was unable to detect my phone, so i decided to root my phone and go for a custom rom, the cyanogenmod13 nightly (i don't really know what i was thinking at that point :s ) and when done i was stuck in a bootloop, so i tried flashing a stock rom kdz method but the lg flash tool would stop automatically. since then i've been trying to flash stock TOT roms, the process would stop at 94% and the phone reboots. the screen shows random pixels and lines, the start up lg tune is there and i feel vibration when i press the home buttons location, i've tried to reset it to factory settings and i've used theLGUP_8974.dll, selecting the BOARD DL option in the lg flash tool but that didn't solve the problem. i have read somwhere that it could be a kernal problem, i don't know if i should go that way ( am at that point where i don't want to mess up my device anymore xD ) what do you guys think?
thank you for your help

Sounds like to me you may not have a D802. You'll need to take the back cover off, and look and see what model #s you see. As if your having screen issues that sounds like your flashing a D802 firmware on a D800 or D801.
Also remember flashing will almost always stop before 99%.. Anything after 85% its done this is normal and will almost always happen.
These D802's have a LONG history (mostly bought referbs) of not being what they are being sold as.
