if the tot or kdz are for H815EU, then it will works for any other H815x (including H815p).

I'm a H815p's user too.

do u know a way to check the roll back version from the download mode or the fastboot mode

AFAIK, the H815p don't have anti-rollback... so you should have ARB v0

 

[fffirass]

oh , thx then what the problem could be btw i am downloading the tot file for h815

Hey..
I have exact the same Problem while upgrading to 7.0 via tot File. After update stucks after 21% and get same error - 0x2000 invalid command response.
After Battery pulling i´ve used LG Bridge in Software Update Tab and use Correct update error, but LG Bridge tells me there is no Update Error, my System is up to date

I changed some LGUP 8994.dll files, there are some out there...nothing is working.
Try to "downgrade" H81520D_6.0.00_0115.kdz via LGUP, but after 21% it fails too.

So, what next ? Any one a working Idea for me ? Thank you.

Use v20p!

Hey the_naxhoo !
Thank you for Helping, 20p was my Key.
I´ve flashed the H81520p_00_0314.kdz.
There are some 20p Versions out there and tested them all, but only the H81520p_00_0314.kdz was worked for me after i´ve extracted the LGUP_8994.dll from the H81520p_00_0314.kdz file with the Tool Windows LGFirmwareExtract-1.2.6.1

Puhhh, i´m so Happy now.
Thank you all PPl here in XDA and wish you all a Wonderfull Christmas !

You tried the H81520p_00_0314.kdz Rom ? Only this Rom version is working for you.

LG H815 - error on every firmware

Hi guys,

I have same problem, already been through all the solutions that I have found, including H81520p_00_0314.kdz and replacing DLL from this firmware. Still got error 0x2000 :/ Any ideas? I have checked mainboar and model is H815 without any letter after.

OK, some update - extracting DLL helped, I can flash firmware, but phone stucks on LG logo and don't want to boot up :/

Hello,

Thank you so much, this method worked - H81520p_00_0314.kdz.
Now how can I install another version of android 6, which is officially in Romania? I honestly do not know which version I should install! (V20?-EUR-xx)?
Please give me all the steps to follow to install an official version.

Thx.

PS: my phone is LG H815 International version, Carrier less.
