Hi all, I'm trying to downgrade my LG G4 H815 from v20p to v20g. This because I downgraded from v29a and only v20p flashing was successful (through lgup). Now I need to downgrade to v20g but I cannot do it and I didn't find anything on the Internet. I tried both with 0.0.3.2.3 and 0.0.4 dll versions on lgup and it sticks (both with v20p and v29a).
What can I do? I have to downgrade to lollipop and then upgrade?
Note: I have unlocked bootloader and the possibility to root and install twrp.
Thanks in advance

Hey there,
I actually have an V10i rooted stock on my G3 (D855 version, rooted with Towelroot).
Can I upgrade it with the OTA V10n proposed, without losing the root ?
Anyone here have already did it ?
Tks for the answers.

No OTA will remove root or brick your phone if you have twrp installed
Flash 10n kdz and reroot using purpledrake

Or flash any other version (V10A,B,C ...), then OTA to V10n and root.

but now i'm in boot loop, already did a hard heset but still nothing
Can anyone help me upgrade to the latest factory firmware (MM) from LP? I origionally downgraded with LGUP and rooted. Then i had a bootloop and was only able to use the LP firmware via LGUP again, and instead of rooting 13b again i would like to go to MM and try the UsU and Magisk method i found...
Can anyone tell me how I can get to MM? or link me to firmware or a TUT? No updates show up as a OTA on the phone...
