Downgrade from MM to LP - G4 Q&A, Help & Troubleshooting

What's the best way to dwongrade from Android 6.0 MM to Android 5.1 LP?
I have the original 5.1 system image which I aquired using the method from HERE.
Can I safely flash this image over the current 6.0 MM one or should I use LG-UP and a kdz file?

Use lg up and kdz

Also when using LG UP. If you do Refurb from the get go, it'll be expecting a TOT file instead. You need to select that third radio button, select the KDZ, and then close, and choose refurb if it didn't default there already. The filepath will already be specified.

I downgraded using LG UP and everything went fine.
When selecting a file I just wrote the file name and pressed enter.

There is lot of attention bloat in there you will have to disable lot of stuff and add an to have data working.

good luck meaning dont know if your T-mo moden will work but you can always try
So your on the att note 2? If I and other tmo users try using the one click I think we would just end up in bootloop because of the modem included

When you flash the TOT or KDZ you flash the modem too so no need flash any baseband.

Think you're misunderstanding his question. Hes asking if he can flash the new baseband on a different rom that he uses for his E986. Im also wondering if this can be done on the E988. Ive done this before on my previous Sony Xperia

Baseband aka modem on stock ROMS can't be changed by flashing
only when you use LG Tools but with
KK based Stock Roms not sure.

[Q] no 4g after kdz flash e98620a

I flashed via Lgflashtool the turkish kitkat kdz rom to my e986.
But now i only have 2 and 3 g. There isnt any option to choose 4 g anymore.
Is this normal?
I have the exact same problem and I have posted a lot of questions about that, but no one seems to be able to solve the problem. I wish you good luck and you will be more lucky and find the answer.

That's not the problem, if you can connect to internet through 3g the APN settings are correct, something else seems to be the problem, but thanks anyway

Thats curios. I flashed several times 4.1.2 via lg flash tool. It always had 4g option.
Only by flashing e98620a kdz,which is turkish kitkat,i dont get 4 g.
Its not so important at ghe moment as with 3 g its fast enough, but wojld be happy if all wofks correct.

Yes. You have to put manualy your apn from Free and install 4G switcher from the play store and chose with this application LTE GSM WCDMA and you have 4G. The only problem it's you have to choose LTE GSM WCDMA with the application each time you reboot your phone to have 4G. Take mabe 30sec... That's the only problem with Free Mobile and 4.4.2.

I want to unroot and recovery to stock rom [D855]

Hey guys,
I'm using LG G3 installed BlissRom. Now, I decide to use stock ROM and unroot it.
I cannot find the information in a topic how to unroot it.
P.S. I try to use LGUP for flash the stock ROM. Unfortunately, It's found my model as unknown and doesn't allow me to continued.
When you flash the stock rom, it takes way the root privileges. Just flash the stock rom
