Return to stock rom when rooted already - D852

I have a LG G3 D852 that I rooted and installed TRWP on it. I modified many things on this stock lollipop rom. I want to return it back to original condition. I tried the factory reset and it works except it says "Unfortunately, home is not responding." I cant get into the home screen.

Is there a way I can flash a rom to get it back to stock?

D852 power on/off issue

First off, sorry if this was answered before, I searched but there is little info to be found about the D852 in particular.

The phone is from Fido, which should be the same as Rogers since they are the same company. The original firmware was 20c, Lollipop 5.0.1. The phone is currently running TWRP 2.8.7.0 and CM12.1 nightlies.

The main issue is when I power off either in System or Recovery, SOMETIMES it will not power back on without pulling the battery. The odd thing is the randomness of it, I cannot figure out a pattern.

I also tried the CM recovery that ships with the CM nightlies. I tried several revisions of those CM nightlies. I tried several TWRP revisions as well. Same power off/on issue, which brings be to believe this may be a bootloader issue.

Any ideas what I should try next? I could try reflashing the original software that came with the phone, but I'd like that to be a last resort. I spent far too much time rooting, flashing TWRP and CM to revert.

Thanks for reading.

d852 issue with Lollipop and rogers internet. please help

Hi All,

I've been reading a lot of the development post and could not fix my issue yet. Hopefully someone can help here.

I have a Rogers d852 with kitkat and rooted.

I'm trying to install a candy5 lollipop custom rom and when I do that, I cannot connect to the roger internet.... it also does not allow me to connect to 5ghz wifi until I install the lp_modem... anyways, after installing the modem, the wifi works but still no roger internet at all... even after selecting the right APN.

I also tried installing the modem and then the stock lollipop rom and it works fine....
when I put the candy5 rom on after, I lose the networks again...


What am I missing here to have custom roms other than the stock lollipop rom working with the right modem?


thanks

Launcher for LG G3 D852

What's the best launcher for the LG G3 D852?

On my previous Nexus 4, I used AWS and I liked it. I'm assuming LG is :TouchWiz? Is that the best? Least resource intensive?
