[Q] Flash Verizon to Att - G3 Q&A, Help & Troubleshooting

Hey everyone it has been years since I have rooted, but I want some help and info. I Just switched back to att and I have a Verizon LG g3 in the drawer. I want to know if I should just use as is or try to, if even possible, flash ATT firmware on it or international firmware on it? If att firmware can be put on it, will it get att software updates?

Simple answer to all questions is no. If we could , it would be all over XDA g3 forum

Don't flash ROMs on other people's phones if they can't troubleshoot and issues themselves. Just a good rule of thumb.
And no it won't brick her phone. Only if you flash the modem/radio for Sprint will it do damage. Depends what ROM you bare flashing to know what the issues will be.

T-Mobile 4.1.2 is a lot more compatible than Sprint's.
Why ask a question if you already have you mind made up ?

At&t S3

I have a question I'll be buying a At&t S3 from someone on Friday it's not unlocked but I'll be unlocking it for tmobile cause that's what I use currently. So the question is once I unlock it and root it do I use tmobile S3 roms or do I use the AT&T custom roms ?

AT&T roms only. Your hardware is still AT&T so your software should be AT&T.
If you use a rom for another phone company's phone, you risk the chance of bricking.

Please search the forum next time. Add of right now there is no T-Mobile root. Some devs are working on a universal for for all of the G3's and there is no ETA for it yet. There is a time l rumor about possibly getting root if and when TWRP comes out but nothing's confirmed yet.

G2 Band Question

I am needing a phone that will support all bands in the UK and for ATT in the US.
Will any version of the LG G2(not g3) have the capabilities of what I am needing?
If so, is there any software tweeks that are needed?
Thank you for your time,
Dustin

Wrong forum . g3 forum here.
And they all work in the U.S. and uk but not at full speed lte and 4g if data works at all.
You would need one of each g2 euro or U.S. version

So if I am wanting full speed and data it looks like its the D802 or nothing? No software tricks, its lack of hardware?

Go to G2 forum and ask!
Wasn't it illegal for companies to have a locked bootloader? Or was it about rooting?
And why are they doing it, we pay for the phones and own it, we have the right to do whatever with it.
Yes, you do. They cannot imprison you for it, except maybe Qualcomm for the Kindle Fire HD, maybe.
So, go ahead and unlock your boot loader without fear. If you can. They don't have to make it easy for you.
