Did anyone test this on a virtual machine (VirtualBox) running Windows 7 on a Ubuntu host? I use Ubuntu and when I tried to follow this instructions the process got stucked on 9% with a "Dload" message on the application. Any clues?

Edit: The problem was with my Windows 7 installation. I managed to install a fresh Windows 8 on a Virtual Box running on a Ubuntu 15.10 host and it worked just fine on the first try. Thanks a lot.

Even if you manage to flash the boot image, you phone would not start. I guess, this is what the locked bootloader is good for in the first place. MM + locked bootloader = no root.

So I had strange experience using LGUP

Win7 x64, downloaded kdz

connected phone, all drivers installed, selected upgrade and kdz file - click start

after 2-3 seconds a message pops up, saying, "installation failed, click [start] to continue" (can't remember exact wording)

in the mean time phone rebooted to download mode - and install continued as normal (I never closed the popup, just let it run)

in the end all went fine, but that message scared the sh** out of me.. :crying:

[G4 Q&A, Help & Troubleshooting] anl2304:
I THINK it did. I say think because I had to go back to 5.1.1 and I cannot truly remember. It did have a strange designation. My observations:

Doze is great. Standby time as a result is exceptional. However, there was considerable battery drain when connected to bluetooth (i.e., no phonecall, just connected). When making a phonecall, the drain was even greater. I did notice Bluetooth audio was not as clear as it was on 5.1.1. The phone is a little smoother on 6.0. My signal on 6.0 was about the same as 5.1.1. I did have to enter the correct APN settings for AT&T manually.

I was planning to keep 6.0 on the phone through the work week, but the following day (Sunday), the phone stopped taking my unlock PIN and google password (which was the backup if the PIN were "forgotten"). So I had two options: 1) new install of 6.0 or 2) downgrade to 5.1.1 (both with full wipes). I chose the latter as the safer of two options.

edit:flashed the h81510d kdz, same thing. This is how the proccedure goes. Phone connects i press start all goes well, then at about 85%~ dont remember how much exactly when it says reboot 150sec, and phone reboots once, its dead. infinite bootloop.

[G4 Q&A, Help & Troubleshooting] galerio:
No write permission to microSD after upgrading. I have a microSD formatted by phone (FAT32) when I was on LP. Yesterday I have upgraded to 20B with LGUP and I have noticed 2 things:

1- the internal memory was renamed from storage/sdcard0/ to a shortcut named "sdcard" that points to /storage/emulated/0 and so I've lost the connections between apps and their databases stored on internal memory.

2- The write permission is missing on the microSD for all the apps installed by myself! The situation is this: solid Explore, EsFile Explorer, every photocamera apps I have manually installed gets write permission denied. All apps but the ones from the rom! So the file explorer of the rom can write on the MicroSD, the photocamera app of the rom can do it and so on. I have tried to format the microSD from FAT32 to ExFat with my pc, but nothing changed. Still have access denied.
[G4 Q&A, Help & Troubleshooting] pomponazzo:
No trouble for me with ES file explorer, but there was a first step when I opened it for the first time in order to define the Sd card path (if I recall correctly). I think another app asked for the same to get the write permissions, I don't remember which one now...

Wasn't it the case for you?

By the way, UK H815, 20A from LG Bridge, and factory reset (never tried Polish pre-release).
[G4 Q&A, Help & Troubleshooting] goran_oh:
Sd card works ok?
[G4 Q&A, Help & Troubleshooting] pomponazzo:
Yes it works fine with ES explorer.
[G4 Q&A, Help & Troubleshooting] galerio:
Yes, ES File Explorer asks me to find the right location of my SD card too, and now it works. But it is the only app! All others that use sd card don't work. SnapCamera for example can't write files on sd! The same with Solid Explorer and others.
[G4 Q&A, Help & Troubleshooting] pomponazzo:
galerio, I just installed Solid explorer to be sure, it asked me the same question as ES about did the SD location, I granted all permissions, and it works all right with my SD!

Maybe apps just need to be updated, in order to ask the right permissions to write to SD on startup now with MM?
[G4 Q&A, Help & Troubleshooting] galerio:
Well, maybe this is the problem, I've made an upgrade, so I haven't reinstalled the apps. I'll try to remove some problematic apps and reinstall it. Hope it works. Thanks.

----

Just tried: Solid Explorer asked me to gain permission to access the SD card. Now it reads and writes on sd, but... it doesn't read the internal memory anymore!!! Ahahah! Damn!

SnapCamera can't save on sd even if I removed and reinstalled it.

I think it's time for a full wipe and a new custom rom.

Hay peeps just a update on my experience on mm , ive been on mm for a few days the HE520a kdz and it was great at first , knock knock code was missing but apart from that it was OK .

Then I started to run into a few problems like when some one phoned me my phone would not ring and just say I had a missed call I checked all the settings and it was set to ring and was not in do not disturb mode and I started to get internet drops alot and for me I depend on my internet connection alot ( lets just say that the wifi at work is not the best ) so I downgraded went to downgrade to lollipop which worked great, I then connected my phone to me pc to upgrade back to the latest version ( just to note im in the UK and on the ee network ) and when my phone went to upgrade it kept disconnecting about 10% into the update , i made the lg up was shut down and nothing would work , I did the whole take battery out whilst plugged in and not plugged it , i followed the on screen instructions from LG Bridge and it still would not work .

So after trying everything I uninstalled all the files that I downloaded for Lg up and retried to flash my phone through LG bridge and it worked and once it was updated I had to do a fresh install because my phone would not still ring and was getting constant internet drops , how ever once I wiped my device I can safely say its all working again , this is great if you want to upgrade to mm early and it may work for you every device is different and I appreciate the work that people put into giving us what we want . don't stop the hard work and thank you
