I picked up this tablet not knowing there is zero community backing. The radio is locked to Rogers and the OS on it is 3.01, v905r-10c baseband. Are there any guides to install newest software? 3.1? The t-Mobile update is only available in US. Only way possible I think is with .kdz file but I've yet to come across one. Help? Input?
Well, there is a bit of development still going on at the rootzwiki site
http://rootzwiki.com/forum/125-lg-g-slate-development/
I also have a rogers v905r but I flashed the t-mobile ota update about a year ago and it ended up screwing up my 3g radio. Since then I believe that they've made a cm10 rom that is flashable without overwriting the radio partition.
Also, if you'd be able/willing to make a copy of your stock v905r baseband it might be the break all of us other v905r users with broken 3g have been waiting for!
I would like to install a T-Mobile Rom or at least the flash the modem files on a Verizon S4. I switched it to T-Mobile prepaid and I feel it would have better service if I did that. Is this possible? I tried flashing basebands and a rom (i don't remember which one) and it didn't work.
You won't get better service. Only thing you can do is update modem for YOUR device, and make sure you have correct apn. Flashing rom is possible I believe but don't know the procedure, try searching the verizon forums
If flashing a T-Mobile rom won't help then I won't even bother. So updating the modem for my device may help reception for another carrier even though the baseband is for Verizon? Unless my understanding of modem/baseband is wrong. I thought that was what told the phone how to communicate with that particular carrier.
It may to some extent, but modems are not interchangeable with these devices
Dear LG Friends,
Long time XDA member, coming from the Windows Phone days HTC, then to Android HTC, bunch of Samsungs, and am now thinking about the LG space. More specifically moving from the Note 3 (T-Mobile US) running on the AT&T US, to the LG G3.
Before I do, I need some help from you guys. Which variant should I go for? I know my primary choices will be the T-Mobile and the AT&T variants (I believe they are 851 and 850)? Based on what's important to me, below, can you guys advise which variant to get?:
1. Development Support - Which variant has the MOST amount of Custom ROM options, that is on-going and kept current? I am spoiled with the Note 3, which has a massive development support. I have never tried the LG OS/Skin (escaping me what it's called), but if it's anything like the TouchWiz on Samsungs, I think it will be important to have CM/AOSP/AOKP and etc support.
2. This is related to # 1 - But I heard that only T-Mobile has the unlocked Bootloader? However, doing some research, I believe the AT&T and the Verizon and Sprint variants can also be unlocked? Is this true? If so, are they anymore limited than the factory unlocked T-Mobile variant?
3. LTE bands - I will most likely be using the phone on AT&T US, but if development options/support are higher on other variants, I might consider buying those models, even if they are missing some AT&T bands. For the Note 3 - T-Mobile is a Pentaband phone, meaning it had all the bands needed, so it could easily work on AT&T LTE, all the time. The reverse was not true.
And basically that is it. Initial instinct says to go chase the T-Mobile variant, based on my needs above. But please educate me and help me out if I have missed something. Thank you so much in advance!
Any input guys?

If you want OTA updates i suggest sticking with the AT&T variant since you have a valid AT&T sim. If you use a AT&T sim in a T-Mobile variant you wont ever get OTA updates and that means missing out on necessary fixes
1. All 3 US Variants are mostly the same, all have CM12 and all the random obscure AOSP roms as well
2. Well unlocked bootloader isnt that fancy it just means theres fastboot mode compared with the other editions where fastboot mode doesnt work properly even if you enable it. It essentially just makes installing TWRP easier since you dont have to root before installing it unlike other variants
Nevertheless Lollipop can be rooted on all US Variants right now really easily. But the only downside to it is that removing custom roms sometimes can be a pain since you have to use a way where it sometimes works and sometimes doesnt

Hi Friend,
Thanks for your response, this is very helpful!
No OTA is never a thing I consider. Everything that matters to me, is what I listed already.
So, is the development support (new ROMs, updates and etc) the same for all US variants or would you say one variant is particularly more popular?
As for the locked bootloader, I thought you needed an Unlocked bootloader to flash Custom ROMs, no? It seems like "Bump" fixes this for Verizon, Sprint, and AT&T and gets you TWRP on your phone, but do we need to do extra steps everything to the boot.img for non T-Mobile variants? Or is it a one time mod and then regular flashing and Backups with TWRP?
If it's the same for all variants after Bump, then you're right, I will likely stay with an AT&T variant, thanks to that Band 7 LTE.
Thank you again for your help, hopefully more can chime in !

No need for any steps. Its just install TWRP and your on your way to installing whatever rom you want
Unlocked bootloader means that the system doesnt security (consistency) checks on system partitions
For LG G3, its because someone cracked the encryption for the kitkat android bootloader which means people can sign non stock boot.img without having to worry about unlocking the bootloader.

Gotcha, thanks again mate! Another (hopefully last) question. If I buy G3, where someone had already OTA'd to 5.0+, will I still be able to root it, install TWRP and get KK ROMs, like CM11 or something?
And vice versa, if the phone comes with KK, do I need to patch with Bump and then I can install ROMs?
Thank you again!

You can root it but i dont know if installing TWRP will work. I didnt want to try it incase it doesnt work and it runs the factory reset script instead. That happened to me once before
But i would say just to be sure, downgrade back to KitKat to do it
Yeah, if the phone comes with KitKat just root, install TWRP using root permissions and then your on your way

This is helpful, once again bud. So how would I downgrade back to KK? Would I have to run a stock firmware of some sort? In Samsung, he Flash a .Tar file through their flashing tool called the Odin. Would that be similarly done here?
I've been seeing many other threads being created about this sort of topic and none of them really came to be useful in my sort of situation. I'm in a need of seeking help from anyone that could help me domestically (not internationally) perm. unlock my S4 without anything coming out of my pocket. The thing is, the S4 is locked towards MetroPCS and i'm unsure if T-Mobile will let me since both company's are considered to be one, but the phone is originally from Metro and not them, so I doubt they'll do it, I also doubt MetroPCS will let me either since I haven't had service directly with them for over a year, and this phone is extremely old. Any advice will be appreciated.
Which ROM is on the phone?
The only free method that may work would be to replace the phone's current modem to the 4.2.2 modem, root, run regionlockaway, flash back to the phone's current modem.

That seems useful actually, will try as soon as possible. Also i'm on the stock 4.4.4 ROM, so things should run more better. Thanks for the help
Edit: I haven't had any luck to grab the 4.2.2 modem and fw from any other providers. Do you know anywhere I could get the modem off of? Thanks
Hey guys! I have an LG G8 Thinq (LM-G820UM), stock OS, no root. I use Mint Mobile in the US.
I configured the APN settings according to Mint's website and I can call, send SMS/MMS, and get internet access just fine. But, I can't seem to use WiFi calling (though it's enabled on my Mint account) and I have not received a software update since March of 2021.
It says I am on the latest software version, but I have Android 10, and I've heard other Mint users are on 11 or even 12 with the same phone.
What can you recommend for me to make this work? I'd prefer not to root, but I am willing to. Can anyone ELI5 or link me a guide to fix this?
Thank you!

Well first, Mint is not a carrier, they are an MVNO. They 'resell' T-Mobile network. So, it's not Mint that would update the OS, it would be whatever OS was originally (or rather currently) on the device.
So Mint doesn't care what OS variant you're using (Sprint, VZW, ATT, etc), but that' doesn't mean all the features will work (like vowifi).
I use Mint and have found that crossflashing my Sprint device to the latest US Open OS version (a11), everything will work; VoLTE, VoWifi, data, sms/mms, etc.
Mostly, the only way you would see an OTA update is if you are using the correct OS and that carriers network. That's not completely accurate though, some carriers will send an update over wifi without a (usually needed) carrier specific sim card, but that's hit or miss, no guarantees (I've had a Sprint phone that did it, but ATT is known to never do it).
You don't have to root to crossflash. But it's a real good idea to back up your entire rom before doing anything, or at the very least the essential partitions that are specific to your phone.
cheers

Thanks so much for the explanation and the advice! I will begin researching crossflashing, pretty sure I've seen a couple of detailed posts here about it.
Is there a method to backup my ROM without root? I'm familiar with the process with TWRP installed, but not sure how to do it without. Would it be easier to just unlock the bootloader, flash TWRP + Magisk, backup, and then crossflash, rather than do it all without root?
Also, were you able to get an OTA update from Mint/T-Mobile once you crossflashed to the US Open OS version? Or would I have to flash an Android 12 ROM to upgrade?
Thanks again for the help, apologies for my newbieness. Just trying to get all my ducks in a row before I get hasty and brick my phone. lol

No worries, all good questions and not that easy to find the answers.
The best back-up method, imho, is to use the bkerler edl utilities (g search that, you'll find the github page).
Using twrp, what you can backup will be limited, but you can use dd commands to backup via twrp adb interface, but that's very time consuming.
I've never gotten an OTA update on LG phone if not running their specific OS, and not rooted or crossflashed to it. But, no big deal as pretty much now, there are no updates. Only the available KDZ and after flashing / xflashing to one of them, there won't be updates to it.
At this time, LG has not released any a12 roms, afaik. There are supposedly 'plans' to do so, but I'd bet it never happens.
cheers
