Missing DLL file for AT&T V10 (H90020j)

Hello, sorry if this has already been covered, I've been searching for 2 days straight now (I'm new). So, my V10 froze a couple of days ago and restarted, then it got stuck on the LG screen. It made it to the AT&T logo twice, but then went back to the LG screen. Will not boot into Android.

I have been trying to flash my phone but keep running into issues. There seem to be two (2) programs called LGFlashTool, one of which requires a .kdz file (does not seem to exist for the H900). The other requires a .tot (found it!) and a .dll. I would really like to find this .dll file so I can flash my phone and hopefully get it working again. I'm not even trying to root it, just want to boot it up again without exchanging my phone and loosing all of my photos and videos.

There is also the LGUP program, and multiple articles about how to use it. I installed the LGUP_8994 DLL and the Store_Frame_Ver_1_14_3 version of the program. I then copied the common folder into the appropriate location. When I plug my phone in on download mode and open LGUP, it says "DLL for H90020j is not installed properly. Please install a DLL package (*.msi) for the model".

Can someone please help me find this .dll file or tell me what I am doing wrong here? All of the guides make this sound like my grandma could pull this off.

I am sorry, but proceed no further. You would be at risk for bricking your phone. There is currently no firmware available for H90020j. There is however firmware for H90010f, but you are already on Marshmallow. You will just have to be patient while we try to find a way to root the device.

There is a sticky in the lg v10 General thread for doing a .tot update. You don't need the .dll file to do the .20j update. All you need to do is download lg drivers, change the lg modem mode to com41 , follow the instructions I think there is a video also. The lgup app will take the .tot file and then it'll be flashing in refurbished mode. This will clean wipe your system to stock 6.0 marshmallow

dear all, i have been trying by myself going thru xda to solve the above issue (missing the h900 model dll). history is i messed the build.prop and the v10 att h900 goes into (bootloop?) LG logo and never got up and i tried to hard reset (showed the yes yes screen) and after that been looking at LG logo for many hours now :(

tried dl-ed LGUP but ended with unknown (shows usb port 41) and searched for a solution (including the common patch): restart after reinstall (dll first then switch), use run as admin in xp and vista compatible mode... without success and looking into LG Flash Tools route -

LG flash tool method i dl-ed 'rootedH900 TOT' and 'rootedsystemh900' file from some private file server (with xp background?) but again, struck at the v10 model dll file to start...

last attempt dl-ed LG Mobile Tools and happy to know that download mode is working still (picked up by LG Mobile Tools on phone model and updates of recovery file) so i dl-ed the 1.89gb file but failed to connect to the phone to begin updates...

dear all senior, i just bought this 2nd hand from somebody happily and ended semi-bricked by my greed to streamline the performance... i seek all senior's kind understanding and help guide me to recover my v10 - many thanks in advance

i had skyped Tungkickk777 and waiting for his add approval... while waiting, please guide me. many thanks again! - v10 newbie

previous root experience - G3, G4
