[G3 Q&A, Help & Troubleshooting] murciano79:
Hello everyone from Murcia!

First of all, sorry for my bad English. I hope you can understand me. I'll try my best.

I come from HTCMania.com to see if I can solve here some specific doubts I have, so I am able to replace the ROM soon.

As a good computer documentary (digital documentalist), I like to share my experiences from my humble contribution in appreciation for so many hours of work shared altruistically, when there is no advertising, at least initially, although sometimes I understand it.

There are times that because of lack of time I do not investigate more on this forum to find out about things, and here you can not always help to everyone or there is no luck to be replied.

I'm very afraid to damage my cell phone even though there are tutorials to unbrick it.

As you know, each one establishes his own goals of how far anyone wants to get complicated life in this world, some because they are good programming and therefore are developers, others are satisfied with less, but in different degrees of depth knowledge, so there are different groups. Well, I fit into the second group, but I would like to install the ROMs cleanly.

I'm not going to do a lot of experiments to the mobile, just the right ones, I know perfectly well where I can get in and where not, because in advanced configuration issues of kernel, CPU and battery I prefer not to go deep in changing codes (sometimes I have tested some tweaks to get more performance, but I am not interested in testing all I read, because although I know the logging tools and other tweaks, having studied the forum for years, I'm scared, although I dabble in Odin and several Samsung models and a Sony with two bricks and then other installations of simple ROMS without complicate too much my life.

Until then my introduction, I start by asking the questions:

1) Do you need to do wipes three times or when you are going to format?

2) I would like to know if it is worth with the current versions of Android to have the root if one is not clumsy, simply to be able to use some application that requires it or if it improves the consumption of the battery.

3) What root method is best today for the LG G3 D855?

4) Is it worth upgrading from Android 6 to 7 or not because it is not the latest version of ROM Stock? Does it work well if anyone have tried on some Custom ROM?

5) What is the difference between revision 30N and 30B of LG firmware for Android M. I suppose some security bugs are corrected, but referring to what? Is it referred only improvements in stability, battery consumption and performance without specifying more anyplace? Is it worth upgrading to 30N knowing that it does not have root, are those improvements so significant?

6) Do the MultiROM work well?

I think my questions are interesting, even if for many they are easy to answer. At least they seem very useful to me if you answer them and I will archive your answers so as not to forget and to consult them.

I ask those questions because I found it harder to find an answer to them in the forum or board. As soon as anyone respond and from the data they visualize in my profile, I will get to work, but first I need to be sure of those things.

Many will already know this, but I not, and many others will not either.

Thank you very much in advance.

Regards!

Pedro
