Advice on rooting, creating backup, and installing custom ROM - G3 Q&A, Help & Troubleshooting

Hi, guys...I just unrooted, factory restored, and used flashtool to fully restore my sprint lgls990 following some connectivity issues. My phone is currently on android 4.4.2.
I am seeking some advice/help on basically end-to-end help. Initially, I used stump to root my phone and then installed xposed and a few other items.
What I want to do now is run the easiest root possible, create a backup, and then install a custom rom. Specifically, I'd like to use CM10 CM11: Royal Blue Cobalt from the Play Store.
I have a strong concern about rom stability, though. I want/need lte data, wifi, phone, playstore, maps, and the like, but don't want to sprint bloatware crap. Is that what a custom ROM does, keep the essentials and dump the carrier crap?
So:
I think using stump will be the easiest root process.
I have read lots about twrp, but haven't found very good instructions for a noob like me, can anyone point me to "the" thread for installing and using twrp?
Where do I find the rom so I can use the theme I have noted above?
Basically, I'm looking for a roadmap for the threads I'll need to accomplish this.
Thanks in advance for helping this noob...

Bump for a little help, please...
Is there a one-stop shop for rooting, backing up, and installing a custom ROM?

Ok - re-used stump root to re-root my phone. Dl'd root checker to confirm and it confirmed rooted. Though root checker says to dl supersu to verify root, I didn't initially. Subsequently, dl'd supersu, granted root checker access, and confirmed root.
Now I wonder if I back up now or if I should have backed up before root? Answer: Seems that I cannot make a nandroid backup without recovery and to have recovery my boot loader needs to be unlocked, er rooted, right?
Edit:
Seems unlocking the boot loader is different than rooting the phone.
I suppose I can just use TWRP to back up the device?
Edit 2:
Okay, using this site - http://lg-g3.wonderhowto.com/how-to/unlock-bootloader-install-custom-recovery-lg-g3-0157830/ - I dl'd flashify, dl'd my ls990 img to the phone via the guide and will install next.
Edit 3:
Successfully installed the lg ls990 .img via Flashify; re-booted into twrp; and successfully created a backup. Then I connected the g3 to my pc and moved the very large backup file to my pc.
Edit 4:
I didn't include EFS in the back up...problem? No problem, just did another backup and chose all options available.
Now on to installing a cm rom...
Edit 5:
Looking for a CM 11 rom for my ls990...found one but the bluetooth doesn't work - http://forum.xda-developers.com/sprint-lg-g3/orig-development/rom-cyanogenmod-11-ls990-t2941164? Dafuq?
Edit 6:
Done for the night...no custom ROM. I thought most of the CM 11s would be sorted out by now, but alas, not so.
I'd really like to get a fully customized theme on this phone and thought going to CM 11 would get me there...

[Q] Which root method?

I had my WF S S-OFF today and now I am looking forward for rooting it. But I am a bit confused about something: I read a tut about rooting WF S 2.3.3 Gingerbread with Gingerbreak apk and I also found this rooting tut on this site : http://forum.xda-developers.com/showthread.php?t=1195275
I didn't tried before being sure to not mess up with my device. So does both methods work or which one is preferred?
Thanks a lot !
My bad, wrong post... linked to the same thread
Good luck dude!
Run gingerbreak, device will restart. You are then rooted.
so you say I don't have to install custom recovery and other stuff to root it ? Just gingerbreak will be okay?
Yes unless you want to have custom roms, then you will need to install a custom recovery which can be found in the development section.
Do I have a chance to restore back the original recovery in case of visiting service if phone gets messed up?
I am wondering if it's possible to use gingerbreak, then install nandroid get everything backed up (not sure if it backups the original recovery in the phone) then un apply gingerbreak and then install custom recovery.
So this way I can restore the backup with original rom and original recovery. Is something like that possible?
Edit :
Is it a good idea / practice to install Clockword Rom Manager as it will replace the recovery menu that I have to install for rooting the device? I am not planning to checkout roms for now, but was just wondering
Nandroid backup is in the custom recovery. You can remove everything if you just install a RUU. Also you cannot backup the original recovery as you need a custom recovery to backup your ROM.
So best practice is using tut on xda, then install Clockword Rom Manager to install nandroid also and take full backup and then play with the phone?
So did i get it correct ?
Yeah, but make sure you install the CWM from the development here or else it won't work. It's very simple to install it. As your phone is S-off you can install the recovery and then backup the original unrooted rom and keep that as a backup.
So
1-) I follow this tut : http://forum.xda-developers.com/showthread.php?t=1195275
2-) Then install this CWM : http://forum.xda-developers.com/showthread.php?t=1213229
3-) Then with using nandroid (I think it's included with CWM? I read something like that on a site) I will take backup of my whole phone (I still wonder how it will backup unrooted version of rom eventho it's rooted)
4-) Remove unnecessary branded stuff (I don't know how to do that, any app for that?)
5-) Then just mess with the phone.
So my last questions is : When I install RUU, it will get back to stock recovery, and when i install the unrooted backup it will be like a legal phone right ? (Of course i will turn S-OFF back)
Sorry for asking noob questions, It's my first time using android phone and it's been only few days since i bought it
You got it all right, except if you have never updated the phone, as there was an update which blocked gingerbreak you don't need to do most of it.
Also when you flash the RUU it will all go stock. S-off will remain as it can't be turned on. Not to my knowledge anyway.
I think I wont use gingerbreak method, I checked for updates when I bought it and it said no updates. So probably that fix is already included in the WF S :/
I didn't managed to find RUU for WF S somehow but i guess for now I don't need it.
Today the guy at service shop (for breaking S-OFF) said that there is way for user to set S-OFF back, but he said he doesn't know the exact way. I thought hard reset will fix it
Thanks a lot for your help !
No problem, also you could just run gingerbreak first just to see if it does work without following the other steps.

Basic root-nothing else- and a few questions

Hi,
So there seem to be quite a few tools and methods out there with which you can root your phone, but what if I really only want to root it and nothing else; my only goal is to use apps that require root access.
I've got Android 4.1.1, but I suppose it shouldn't matter that much. Will I be able to update to a newer version with root access though?
Forgot to add:
What will I need to back up and how do I transfer my settings and contacts? I don't care much for lost apps since I don't have many.
Unlock the bootloader and flash a custom recovery. After that you make a nandroid backup and then install the superuser root script to give root acces in the rom.
Flash back the stock recovery and you are able to receive and install official ota's.
Is this all possible with this tool?
Now I don't want to act dumb or seem inept, but could you or someone else give me a more detailed description, maybe with a link or two?
Yes you can use that tool :thumbup:
Did you see my edit to the first post?
>>What will I need to back up and how do I transfer my settings and contacts? I don't care much for lost apps since I don't have many.
Can you tell me why I need to flash a custom recovery? Can't I 'just' root my phone as is and then leave it like that- rooted of course?
You can use an app called carbon to make a backup. You need a custom recovery to install the super user script. A stock one is not capable if doing that. And you don't root a phone. Only its software !
With hassoons tool, how do I flash the stock ROM back on it? I can see no option in his thread...
The stock nandroid backup needs to be installed via the custom recovery. Not with hassons tool kit. You can in that case only flash back the stock boot.img from the stock backup.
Hi, I decided I wanted to go through with my plans to root the phone and already run into a problem:
http://forum.xda-developers.com/showthread.php?p=43066305&posted=1#post43066305
Most recentpost...
EDIT: Selected Power down on the phone because I was getting impatient and paranoid and then disconnected the phone. Everything seems fine so far. I closed the console and the message "Get Token ID.." popped up and then the console reopened, apparently searching for the phone... -_-
Oh well, maybe next time. Right now I want to take a break/try something else.
Can someone tell me why Windows always trys to install new drivers even when they already are installed? Happened when I used the programm- updating drivers blabla...
I'll try again here...
Just a question:
Can I definitely receive official android/sense/hwatever ota updates but still keep the root access?
What i've gathered so far is that I need to use hassoons tool and how to guide,but only the first post.
After that I will have a rooted stock ROM with ClockworkMod recovery, right?
Then I should do a nandroid backup WITH CWM (how is this done exactly? hold volume down +power button, then recovery?)
What will be backed up with the nandroid backup? How big will this be roughly and can I/should I put it on PC to free up some space?
Regardless from this backup, I only need the recovery.img, which in my case will be MY personal backed up STOCK recovery.img,is that correct?
How do I flash my stock recovery?
Edit:
Once I have the stock recovery again, will my phone still have root access? Is everything from then on -stock- except for root access?

[Q] Root without installing custom recovery g3??

I can see from the questions that you can flash SuperSU and get root without installing a custom recovery on the One Mini but is this possible to do on the LG G3?
I've searched and I can't come up with anything.
I want to root simply to remove apps so I don't want to install CWM/TWRP as having a custom recovery annoys the HELL out of me. I don't understand why a custom recovery is needed? Can't the one that comes with the phone do everything those can?
IMO, they are just there cause they look prettier. LOL
Anyway, I have the T-Mobile G3. I had it rooted but unrooted to install latest update (that was hell, turned out my drivers were not updated). I used PurpleDrake last time but it installed TWRP and as I said, I don't want TWRP.
Any ideas?
Good question! Bumping this for you as I'm interested too!

I have the T-Mobile G3 as well. I rooted and got Supersu way before installing TWRP! It's possible. TWRP is a custom recovery that allows you to backup your entire phone (including software) in case you make a mistake. It also allows you to "flash" things to your phone. It has a lot of features and is needed to install a custom ROM or update that custom ROM.
You don't need it, but I would suggest it highly. The ability to backup everything is a must when you're doing something to your phone. It essentially prevents you from bricking your phone -- which I did. However, I made a full backup before deleting everything, so all I did was go into TWRP and undo the bricking by restoring a backup.
You can root your phone without a custom recovery. Then you can go into the play store and download SuperSu, then you can download Titanium Backup to remove the bloatware. A custom recovery isn't needed for any of this.

[Q] Any reason not to update firmware on new2me G3?

Hi all. This is my first LG phone and I looked around but didn't see any reason not to fully upgrade firmware before I root. Any input any drawbacks of upgrading fully? Also, this is a t-mobile used phone and the back of the battery case has a wireless charging stickon in it. Is this standard for this phone? I havent researched the look/brand of it yet as I have just got it. Thanks. Its a nice phone. Can't wait to get tweaking!

The latest build 10R broke all the rooting tools.
Assuming you are still on build "c" or "m"...
Root first w/ PurpleDrake and make sure it installed (TWRP) custom recovery. It should also install SuperSU but I can't remeber, you may have to read a bit.
I would then update to the latest TWRP version which can be done easily with TWRP manager. Make sure you install busy box when prompted by TWRP manager!
Perform a nandroid backup before updating!!!
Then flash the "R" firmware with TWRP flashable zips available here.
Be certain to flash SuperSU before rebooting! If you forget there is no way to get root again after a reboot.
Good luck...

Thank you. I actually found that out the hard way. Flashed back a version and got root. Wifi calling and text not working yet so I found the exact thread you posted and was gonna try. Great tip on flashing supersu though. I'm new to LG but looking forward to getting this phone right. Thanks for the input.
@Bubba Fett
Here is another great source of various upgrade, downgrade and restore to stock flashing methods and tools including TWRP flashable Stock ROMS. Make sure to read ThePagels OP carefully before proceeding.
Also in the OP: "Strengthens and weaknesses for each method click here" is also well worth reading.

[Q] V50020f Root and Recovery Install?

Hi all. It's been a while since I've flashed anything on my v500, but last night I decided to try and update to the latest TWRP. Well, I soft bricked it somehow. It was running CM 12.x with TRWP great before, but I just had to mess with it. Anyway, I was able to use the LG Mobile Support Tool and I got the pad up and running again, so here I am sitting on stock v50020f 4.4.2 firmware. This is where I'm lost. Most threads I see about rooting/loki/TWRP are for 4.2.2 and below.
I originally used Kingoroot, and was able to get root with that, but couldn't update binaries with SuperSU or SuperUser. I'm not totally comfortable with that method anyway (sending data to Chinese servers and all), so I disabled it. Can anybody point me to threads about successfully rooting and installing custom recovery from 20f? I've been reading around in circles and my head is swimming.
I appreciate any help. I don't need hand-holding, just a push in the right direction.
Thanks!
EDIT: I was able to get root using the ioroot sideload method. Just not sure how to install TWRP.
EDIT2: I installed TWRP using the method in this thread http://forum.xda-developers.com/lg-g-pad-83/orig-development/recovery-official-twrp-t3135886 with Rashr. Went to restore an old backup, and it softbricked again. I'm guessing that backup was corrupt. The TWRP I flashed should have Loki (or whatever bypass) built in, right?
