LG V20 (H91010l) AT&T to Stock LG ROM - LG V20 Questions & Answers

Hi all! Newbie here.
This has been asked before but I need to confirm a few things.
So I just bought a used LG V20 here in the Middle East but only later realized that it is an AT&T unlocked device. I have attached a screenshot of my device software info. It has all the bloatware and is running Nougat December 2016 patch.
I read that AT&T OTA updates can only be received if it the device has the AT&T sim connected to servers in the USA. I want my device to run the original stock ROM by LG and not a carrier one as such.
I searched around and came across this thread which seems to be the closest situation as mine;
https://forum.xda-developers.com/v20/help/remove-att-rom-to-att-stock-rom-t3809173
Considering that I'm not a techie but I can run things with guidelines and the software version on my device is H91010l;
Question 1) Can I just follow the method Brian has mentioned in the thread or is there anything extra that needs to be done? I've read that some devices are blocked to have different firmwares loaded onto them.
Question 2) What kind of backup needs to be taken? I don't have any data on this phone yet so I have nothing to lose but I don't know how to take backups of system files if that's required. A guide on that would be helpful!
Apologies for the long post and repeated questions, but software help here in the Middle East is limited so I don't want to put myself into any trouble with a bricked phone.
Thanks in advance!

Just follow Brian's instructions. You don't have to root if that's what you would like to know.
Just an #FYI, before some "Senior" member gets on your case, you may want to use the search option in the LG V20 forum, as well as the search option within the threads.
Use keywords, such as "H910 to us996 no root." If you use Google search, you can use something like, "H910 to us996 xda." You're going to have to read a lot, compare information on threads, look up videos on YouTube, but know that if language seems to be a barrier, you can ask. And don't be intimidated with some jerks on here. There are plenty of experienced and knowledgeable folks on this forum...but you also have to do your part in research and troubleshooting.

AT&T Version Compatibility

First, I did search before hand, but searching for AT&T returns nothing. I'm guessing it has to do with the "&" symbol. Anyway....
I just gave up waiting for Verizon and picked up the AT&T version of the Nexus One.
I'm one of those people that managed to brick his HTC Magic when trying to switch back and forth between radios, so I guess I'm a little bit leery now.
What I'd like to know is if anyone has determined if the ROMs posted here (mainly Cyanogens ) are compatible with the AT&T Nexus One. I realise that they are just different GSM frequencies, but I just want to confirm that I won't be creating another $600 brick.
I'd also like to confirm that I don't need to switch radios, since thats where I got burned last time, and I'm guessing that most, if not all the radios available, would brick my phone.
There have been a lot of posts about cyanogenmod working without and problems on the ATT Nexus. There are no special procedures to take, just follow the cyanogen wiki here and you will be rooted and running CM in no time
http://wiki.cyanogenmod.com/index.php/Full_Update_Guide_-_Nexus_One_Firmware_to_CyanogenMod
You will NOT have to upgrade or change your radio, so don't worry about that. You will need to unlock the boot loader (which WILL void your warranty), but its literally a one line command, zero chance of bricking there.
From there you will install the AmonRA recovery, and then flash your phone with the current cyanogen. low low low chance of bricking as long as you follow the guide, and are aware of what you are doing.
Good luck!
Next time make sure you post in the correct place. Q&A.
Check the CyanogenMOD thread. He has a link to his wiki with a FAQ page that will answer your question. Also read his instructions to install his ROM and you'll be fine. Just be careful when flashing radio's.
I'm on ATT and I run enomthers rom
http://forum.xda-developers.com/showthread.php?t=614427
It will run on the as shipped radio and runs very good (stable)
I switched from the T-mobile nexus to the AT&T nexus. Both behave exactly the same when it comes to unlocking, custom roms, themes, etc.
The only difference is that the ATT version doesn't have a bunch of radio updates floating around (the default radio is fine).
Thanks to all
Thanks to all who commented. Its nice to get an answer so quickly.
As for posting in the right forum, this is an argument that has been had on other forums before (not by me) so I won't rehash any more then this:
By many (and thats enough to cause confusion), General is seen as general discussion, Q&A is seen as general questions, Accessories is clear, themes and apps is clear, development is seen for modding. Its where ROMs are discussed and distributed. I had a question about modding my phone. I posted in the most logical place.
None the less, thank you again for constructively "correcting" me.

SGH-I337M Model Questions

Hello everyone, new user here - apologies in advance if I'm not following a rule or some related item. I've read the rules, etc, etc, but my mind isn't very good at retaining that sort of information so help me out if I'm doing anything wrong.
Two days ago I purchased a Samsung Galaxy S 4 and I freakin' love it. I've already installed a new launcher (Nova) and have done several changes to my device which puts it more into a zone that I am comfortable with, but after reading further into this I've learned that the best way to get the most out of your device is too root it and install custom ROMs. I'm heavily into the customization aspect of my devices and I'm usually quite knowledgeable about this sort of thing, however doing this on a phone is completely new to me. I've done things like Jailbreaking on iOS for my iPod (which was put to rest by this new guy), but on a phone this is all new to me, especially on a Samsung.
I'm Canadian and what I can gather from the various Q&A threads and various posts around the forum - is that the carrier and model number of your device are very important when rooting. I've checked and the information on my phone is as follows:
Model Number: SGH-I337M
Android Version: 4.2.2
Kernel Version:
3.4.0-897376
[email protected] #1
Not sure if more information is needed, but if it is, by all means ask and I shall provide.
Anyways, I'm looking into this all and I've found several threads - among which this one seems to provide the necessary information I need.
My question is, as is, and assuming I follow the instructions described in that thread, will I successfully root my phone without issues and be able to install/use custom ROMs, etc, or do I need to perform some actions such as downgrading my device firmware, changing something or other around, or whatever else may be neccessary? Or will I seriously screw up my phone?
Also as an added side note, my carrier is Rogers Wireless and that will be the only carrier used on the phone, do I need to unlock this thing or can I leave that as is? It doesn't seem like something I'd want to mess with, but will do if necessary.
Thanks in advance for any response! It's greatly appreciated, I just don't want to brick my new baby!

Hi,
Let me direct you to THIS THREAD
You are quite right to root your device with Chainfire's method for the SGH-I337.
Use the rest of that forum ,including the "Stupid questions" thread,to find more information pertaining to your phone.

[Q] LG G2 unlock

Hi! I hope this is being posted in the correct place first and foremost.
I'm pretty pissed to find out today that EE will not be releasing the KitKat update for my G2
I received an email from LG confirming this and so replied with the obvious question 'How can I do it then please? '.
They said I would need to get my phone unlocked from EE. Now, being a complete noob when it comes to this sort of thing I don't really know what I'm doing. So I have a couple of questions I'd like to ask before I attempt any unlocking.
1. Once I've managed to unlock my phone can I still use the Sim Card that came with it? I have a 24 month contract with EE and can't really afford to run two tariffs.....
and
2. Is there not an easier way to go about getting KitKat? I had a Galaxy S2 and when I wanted to upgrade the firmware on there I used ODIN. But I can't seem to find a way that is similar to that for LG phones.......
I apologise if this post is not in the correct thread but I really would appreciate any help anyone could give me.
Many thanks!

well the g2 has a tool like odin if you looked in the general thread there is a return to stock guide which can be used to flash any firmware as long as its for your device, I do know that the d802 can flash any d802 kdz file even if it's for another carrier, I do not own one but you can always ask around to make sure you don't do something wrong

Xt1684 xt1685 uk

Hi guys and gals
Any information on functionality of this model after unlocking bootloader, flashing TWRP and choice of rom.
Why I posted was to check that whoever reads this post can be assured of at least getting the same experience of the stock OS, but with all the goodies that come with Oreo, preferably 64bit version.
One thing I have noticed is that download links tend to have a specific model ie pixel experience shows xt1686 on androidfilehost.
So any information regarding UK only model can be kept in one place, if anyone has spent any time reading the G5plus forums its a right mess between the different models, and the same questions and answers are going around again and again, so for us if having one Country specific post can help any confusion, great in my book.
Any non UK owners, please do not clutter up this thread, suggest you create your own model/country specific new post.
Regards
Ray
I've only just got my xt1685, so haven't rooted yet.
I want to use android pay so need to read up on that first.
I've also have a G3 and I prosume this will be the same and any regnal version for a G5 plus will work.

Is there a reliable way to root my S7 Edge SM-G935A?

I'm not very tech savvy, but rooting this model (S7 Edge SM-935A) seems to be hard according to what I have found. I would like to root it and get rid of all the bloatware and try a custom ROM, but don't want to mess things up. Can anyone point me in the right direction? Thanks very much for any info.
I have an AT&T S7 Edge and wanted to get rid of the bloatware also. I installed this ROM and all is working great. I didn't root device but I have no bloatware. It also get's OTA updates quick.

Not really difficult. Need a special version of odin, modded by someone who goes by the alias Prince Comey. Then must rught click on the exe file in winblowz and select 'run as administrator'.
The non-modded versions will error out and won't complete the flashing process. Must be careful, and be sure that you are are flashing the correct files for your particular phone. I rooted my AT&T S7 Edge by flashing just one file.
The trickiest part is finding the files for your variant, whether it's AT&T, Verizon, or other. Also must install the usb driver for Samsung and the adb driver, both on your windows computer.

Text Message Recovery on S7 Edge (AT&T)
I have an AT&T Samsung S7 Edge (smg935a). I think I need to root mine so I can undelete my text messages. If I am headed in the right direction, can you provide links to the special Odin version and file you flashed?
I'm in the same boat and I think this is the link that leads to the Odin you want.

There is no engineering bootloader available for Oreo yet, so you will have to drop back to Nougat. From there, you can either go with AT&T firmware or the Unlocked firmware, depending on how badly you want WiFi calling and VoLTE. (If you aren't an AT&T customer, this is a really easy call).
Just going with the U firmware will remove the vast majority of the bloat right out of the box. You can root it and get the rest, but I haven't found it to be worth the effort, as the U firmware is pretty good as it is.

Samsung S7 edge and S7 flat variants do not allow TWRP to remain installed upon rebooting. There are ways to still root with it however. I found a post on X.D.A. that states SM-G935A ( AT&T variant of the 7s Edge ) runs fine after flashing the SM-G935U firmware. I had flashed it without issues myself, however I never tested it before running across the comboRom that I was originally looking for. Just place all 5 files in the correct positions ( BL,AP,CP,CSC,USER) of Odin. If Odin is only allowing you to 4 spots to flash. You need to use a different version of Odin. I used the "patched" version of Odin. Unsure if that is one and the same as the prince version.
S7 Edge while 'rooted' at least by the way I had rooted them. Runs very very HOT and lags to the point of annoyance.
So if you 'think' you need to root your phone. Make sure you need to first and fore most because was a back and forth headache to root. make changes, then unroot. then test. then root again. then test agian, then unroot.. etc.
https://forum.xda-developers.com/verizon-s7-edge/development/easyroot-unroot-t3859762
that link is for bootloader V4 to root.
When flashing SU make sure you use the system version and not the system-less version if you follow the instructions for OREO (Android version 8 ). The instructions I originally followed never stated that aspect and I had gone in circles for an hour until i discovered the problem.
Verizon variant had a few different ways to root/un-root, with different walk-thrus of which I 'think' would work with different carriers. Just instead of using the S935V firmware, You would just need to use your carriers firmware while flashing it with Odin but I could be wrong so please double check the comments of whichever way you choose to root your phone for someone else with similar question/concerns as yours.
If you had been using your phone after the messages were deleted ( especially if its been awhile since you deleted them ) then you are likely S.O.L. However if it's worth the time spent for you to try, then it's worth the effort to try.

This thread is only 1 page long with 10 previous posts before yours. Out of those 10 posts, 3-4 of them describes what you're seeking...
Guessing you saw the threads title and bcuz of that you clicked on it and asked your question. Did it ever dawn on you that your question is nearly identical to the title of this thread? This is how forums work, if a threads subject is similar to the subject that you're interested in then, the thread may contain your answer. Next, is where quite a few folks seem to really struggle, sort of like yourself but it's ok, everyone was new once. This is where you'd want to pay close attention, really concentrate and use every bit of brain power to focus on this next step. I'm going to reiterate, just in case I lost ya: You just located a thread that it's title is very similar to a question that you have (you did a good job searching & your instincts to click/open it are on point, well done). A threads title tells you that the discussion(s) inside there relate to that topic. Upon opening the thread, you'll see rectangles vertically aligned, when members add thoughts or ideas to the topic, they're separated by the rectangles. They're arranged in chronological order the top being the first, the most recent or latest entry being the bottom. And thats how forums like this one and many others work. Pretty simple idea, I think, yet its highly effective.
Now, with this knowledge, Im sure your already 10 steps ahead of me, but I'll mention anyway for anyone else. To fully utilize the resourceful contents here, as it contains vast amounts of invaluable info, one must simply READ and COMPREHEND info that pertains to the subject that brought you here. That means reading (& understanding what you just read), each one of the posts inside the threads. No really, it really is that simple! Unless your device is new, theres likely someone who already asked your question or someone already posted a set of instructions describing the task youre needing. You can test this theory with this same thread youve commented in.
Amazing isn't it? By now, you've probably already figured it out and concluded that posting your message which mirrors the first one here wasn't necessary, nor was including your phone number.. If it wasnt already obvious, you're the lone outcast whom shared their number on a public forum. Most of us here, refrain from such similar activity, since the forum has option to directly contact members via the internal private messaging system. Some highly value their privacy and anonymity. But I cant decide for you, obviously you're comfortable with it.

@Talysdaddy
So that was the most condescensing, egotistical, and just blatantly rude response I have ever seen given on this site.. I promise you, I have a very impressive ability to retain knowledge, but considering I was on this site in the first place due to the fact that I have never been interested in, or ever even attempted to mess with my phone before in any type of way, I am slightly uneducated on this PARTICULAR topic. However, that IS NOT because i lack the ability to learn, comprehend and/or retain information, understood?
It is due to the fact that I have never sat down and educated myself on it.. WHICH BY THE WAY, is WHY I'm on this site in the first place, you know that IS the entire PURPOSE of this site? ....
You see how that works? .. Let me break it down for you! Pay close attention and try to follow me and actually comprehend what I am saying! (if you're able to, that is). ANYWAYS, as I was saying, I CAME TO THIS SITE TO TRY TO EDUCATE MYSELF on something I NEEDED to educated on! ALSO to be able to interact with other people, and ask those people questions! To be able to recieve responses from those people, in order to obtain the information THAT I CAME HERE FOR! WHICH BY THE WAY, IS EXACTLY WHAT THIS SITE IS SUPPOSED TO BE USED FOR! Hopefully I have yet to lose you, because this is the most important part! Let's try to read this next part, and actually try and COMPREHEND and UNDERSTAND what I'm saying. I CAME HERE TO USE THIS WEBSITE IN THE EXACT WAY THAT IT IS MEANT TO BE USED! .. To be able to share information! To exchange information! And to obtain information that I am not privy to or an expert on prior to visiting the site!! .. If I was educated on these things I WOULD NOT BE HERE!! Obviously! Soooooo, instead of being an arrogant and cocky JERK, do EVERYONE on this site a huge FAVOR, and next time NOT leave such a RUDE, SMART COMMENT!! Thanks!
P.S. isn't it funny how just from that comment, I could tell you exactly what you look like, the life you live, how insecure you are in yourself, and how you deal with that by trying to belittle others, in an attempt to make yourself feel superior.. BUT, and yes, there is a BUT!! Just because you might know more about this topic than myself, absolutely does not make you ANY more intelligent than myself.. Because I promise, anybody who leaves the response that you left, when I am using the site for its specific purpose in the first place, welllll... let's just say anyone who would do that, and who would do it to boost their superiority complex as a defense to their pathetic insecurities, well, let's just say I would bet my life on the fact that my IQ would make yours look SORT OF like you TRIED to make me look and feel when you left that comment
That's all, hope you find something better to do with your time than this in the future.. it is kind of sad! If you're not here to help, then don't comment! That goes for everyone's posts! Jerk.
