Bought G4 - have couple of questions

[hexen88]

Hi,

1. Is there any option (and guide) how to change stock firmware branded to stock firmware unbranded? And don't loose warranty if I want to repair phone?
2. Why G4 have so small community? This phone is great. Isn't it?

Depends on your model. I think you can just flash an unbranded kdz, if you're on H815 International.
Just use LGUP, download the proper kdz and select "refurbish", when installing via LGUP (note: this will wipe your data and system).

Official LGUP thread
20D kdz from @autoprime

Please note that this kdz is only for H815 - you can check device model under settings --> hardware information

EDIT: You don't have to be rooted or bootloader unlocked to use LGUP - So this won't affect warranty
