I downloaded a KDZ file and tried to load it using LGUP, but it only allows for TOT files. Where as the KDZ is of .kdz extension..

Any ideas? Cheers

Just change .KDZ to.TOT and it'll work the same..

[G4 Q&A, Help & Troubleshooting] bbenz3:
Since the dll I used came from this thread I thought I might ask here also. Does anyone know how to get a newer version. I have bricked my phone through my own stupidity and when I run the LGUP tool it is giving an error message stating the dll isn't installed for the version of MM that I have.

[G4 Q&A, Help & Troubleshooting] bbenz3:

Hi.

How can I downgrade from v10g to other previous LL version ? selecting Refurbish?

[G4 Q&A, Help & Troubleshooting] juannicolas:
Selecting Refurbish will factory reset your devices while installing the version of rom, just to FYI. But yes, that is the right option to select.

Hi ITM. Do you remember where did you download the KDZ file for your TWN version of H815? I also have TWN version and not sure if I need a specific TWN version of LP or can use any LP KDZ file. Thanks!
[G4 Q&A, Help & Troubleshooting] seeee7:
make a backup (its probably the best to use LG Backup and Titanium Backup), then try it out using the UPGRADE option in LGUP. If you lose your data you can try LG Backup on MM and if that doesnt work you can simply flash a lollipop kdz, reroot, and recover your Titanium backup.
[G4 Q&A, Help & Troubleshooting] a tiny ant:
I'm interested in this as well. From what I could find it doesn't matter which version you flash. As long as the model number is correct. However some earlier versions might be susceptible to the Stagefright exploit. I'd personally get the E version from storagecow.

I did hear something about anti rollback in newer versions. I don't have it with my Dutch v20d but some American models/updates have this problem.

You should look this up on XDA. I don't have time now to look up the link but it shouldn't be hard to find.
[G4 Q&A, Help & Troubleshooting] seeee7:
Yeah I used 10c and 10d without a flaw (although 10d gives 10c and 10c gives 10b)

Hi

I tried LGUP, but I can't select kdz files, only .tot files. It doesn't give me the option to allow "all files" or "tot + kdz files" in the drop down menu. What could be the cause of this? I'm on Windows 10 64 Bit, first installed LGUP_8994_DLL_Ver_0_0_3_23.msi, then LGUP_Install_Ver_1_14_3.msi.

instead of *.tot filename type *.kdz and hit enter

You could also put *.tot,*.kdz registry addon in LGUP registry and writeprotect it or make readonly

Hi guys,

I want to revert to LP from MM but LGUP don't recognize my phone... i tried everything without luck, even this:

"ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?

Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it."
