LG G2- Making a Backup, and flashing a new ROM - G2 Q&A, Help & Troubleshooting

Bought the Verizon G2, brought it home, rooted it. So basically I have nothing but Super Su and a crap ton of bloatware haha! Any threads showing me how to make a backup of what I have now, then a tutorial on how to flash a new ROM? I just wanna be safe having a backup recovery of the phone basically all stock with root acess.

You need to Loki first to get TWRP, check the Verizon sub for details. Once you do that you can make a back up of your current phone. Once compete, you can wipe data and flash a new Rom safely. Fyi, the flash takes a long time, just wait it out.

I don't know what LOKI is, but if you're rooted then chose a recovery (twrp or cwm), install it, and then do a nandroid backup. Then you can flash whatever ROM or mod you want.

Pretty sure you don't need Loki...that's for devs only. TWRP is already pre-lokied for your convenience.

^Exactly. Though you should probably use TWRP.

Ok, so what's the real word on the OTA for rooted users?

None of these random workarounds posted in the dev section by random users who just seem to be guessing at things. Is there any word from a real dev working on allowing currently rooted users to install the OTA without un-rooting or flashing things through fastboot? Either by modifying the .zip itself or by creating a method to flash the provided .zip? I'm tired of seeing posts that read along the lines of "Oh, do this in post X then this in post Y and it SHOULD work, but if it doesn't check post Z and hope things work after that."
Download the nandroid backup that was posted. Restore it using Clockwork, then while still in recovery, choose mounts, and then mount /system, then flash the superuser zip from Koush's rooting tutorial, then you will have the OTA stock + rooted + stock recovery + stock boot + everything.
This is how I was able to upgrade.

Yes, but I don't want stock recovery. I want to keep ClockworkMod.

Yes. You're restoring a nandroid.
Read this post, pretty much you're rerooting again and another step so it doesn't keep going back to stock recovery. Easy.

From the nandroid backup OP:
"Edit: According to xda member Luxferro the new update introduced /etc/install-recovery which may have not been in 2.3, but anyways, it runs this on bootup, and if the MD5 of the recovery doesn't match what is expected, it reflashes the stock recovery back over, so if you dont want the stock recovery to be flashed everytime you boot if your on clockwork or another non stock rom, just rename it to prevent it from running on boot. And for those of you who want to return your phone back to stock this nandroid will do that for you since it also flashes the stock recovery."
Just wipe and flash Paul's Gingerbread ROM.

Pretty much every time you flash an OTA update you're gonna lose root.
If someone took the time to modify the OTA update so you don't lose root, then it's not an OTA update anymore

Will I have OTA updates with Clockwork mod?

Sorry if this is redundant, but I tried to find an answer searching. apologies in advance if this is a repeat question.
I've rooted and run custom roms on other android devices in the past, but these were devices that never received OTA updates from the carrier/manufacturers. With that said, I have one single question. If I root my nexus 4 and run clockwork mod recovery, will I still receive OTA updates? I don't want to run a custom rom at this time, but I wouldn't mind doing so in the future. I also want the ability to run titanium backup and adjust the color profile of my screen. Part of the appeal of the nexus 4 is receiving updates directly from google and I would like to keep this feature. Any insight would be appreciated.
I run a mac, so I was planning on running this instruction set as there isn't a toolkit for macs (at least that I know of).
http://www.androidrootz.com/2012/11/how-to-root-nexus-4-on-mac.html
You will receive the update but it will fail at installation because of the custom recovery. You can however, flash the .zip file through recovery to successfully update.
If I simply root my device (keep the bootloader locked and do not install clockwork mod), will I receive OTA updates? I'm a big fan of getting OTA'. I believe I only need root access to run titanium mod and screen calibration tools.
You need to unlock your bootloader to fastboot boot a custom recovery to flash the SU binaries.
If you unlock your bootloader and just boot the custom recovery (not flash it) to gain root, you will get the OTA. It will only install successfully if you keep it stock and don't change the kernel, system UI, or anything else.
I decided to throw caution to the wind. I'm going all in and running clockwork mod and so forth. Very simple to complete. I don't know why I why I was so concerned about the OTA updates.

If it's anything like the Nexus 7 or Galaxy Nexus this isn't true. On those device it will reboot to the recovery and fail initially but it gives you the option to start the installation. Once you do that it installs successfully and then CWMR asks if you want to keep root, then asks if you want to restore permanent recovery.

This must be a new feature of CWR. It wasn't like that in the past.

It could be new. I haven't owned Nexus devices for a long period of time. Running v6+ on all of them.
Edit: I didn't see you were talking about clockwork mod recovery here! Sorry for not reading!

[Q] ParanoidAndroid - should I root before installing?

topic.
N4 is my 2nd Android phone (my 1st is an old HTC Magic) and have never rooted a device before.
I'd like to install PA. So do I need to root it first?
Also I have already installed some apps, I'd like to do backup before factory reset. What is the easiest way for this?
Thank you

Firstly Install carbon backup app (like titanium backup) from the play store to backup your app and app data. It is good because you don't need to root your device in order to backup.
However in order to root, you need to unlock the bootloader which will delete everything from your phone. After that it is easy to root your phone using the guides in the forum. I suggest you don't use toolkit if you want to learn how everything works.
Only after rooting, you can install PA.

You don't need to root. Open boot loader, install custom recovery preferably twrp and you can install the zip files you need. Roms come rooted by default you don't need to worry about that.
i think root will make it easy to install app

Thanks moles. I didn't know that you didn't need to be rooted to your roms. I guess you learn something new everyday. Btw I love your PA roms. This is my first android device and PA is the only ROM I've ever flash. Keep the good work.

I did the "Casual" TWRP Recovery and Root for my AT&T S4 and love it. I booted into recovery and flashed a backup image of my stock device and saved the 3.56 GB nandoid file on both the internal and external SD and put another copy of my original phone image or nandroid or backup or whatever flavor you want to call it, on my PC.
I've frozen 37 phone functions with Titanium Backup and dodged a bullet. I heard there was another over the airwaves update from AT&T a couple days ago, and I am pleased to see it never appeared on my S4. I couldn't be happier. I have yet to try any custom roms as cyanogenmod doesn't seem to be getting any love lately, plus I would not want to give up the universal remote in the on board "watch on" app.
Why do you want to undo TWRP custom recovery and lose root? Titanium Backup needs root. Did you flash a custom rom without going into recovery first and making a backup of your stock handset once you got root and TWRP?
In any case I think there is an Odin thread you need to read: http://forum.xda-developers.com/showthread.php?p=40976805

well.....Theres nothing wrong with TWRP recovery and root, its just that I have no need for it. I have tried a few custom roms and none offer battery life better than that of the stock TW software so I decided to just stay stock. As you said like 2 days ago at&t rolled out another OTA, however I dont think my phone installed it. It booted into TWRP and it started installing a zip. I wasnt sure if that was the OTA or not. I just dont need the TWRP and root as of now and its kind of a hastle in my current state to flash the new OTA's instead of having it automatically install via stock recovery.

[Q] General question about backing up

I'm just starting with android and planning on rooting my phone (vD800) eventually. I made a backup here: all settings> general> backup and reset but I don't think this is what I need for recovering from a failed root. What do I need to get so I can make an image of the phone? I have lots of questions but that'll do it for now.
You need to first root then install custom recovery then make a back up...

What do you mean by failed root? I've never experienced such a thing. To root follow this:
http://forum.xda-developers.com/showpost.php?p=48709232&postcount=869
You don't replace the OS until after the custom recovery (such as TWRP) is installed. So after you install TWRP or whichever recovery you want just boot in to the recovery and then backup there. Then flash whichever ROM you want.
Ok I get the part about not replacing the OS until you are rooted. So just root it and if I fail post here and see if anyone can help?
I guess I'm just trying to be sure I understand what I'm getting into before I do something that could seriously mess up my phone.
You can use the LG backup app on your phone, it's quite good. Then move or copy the backup file to the computer for safekeeping. I did this when I downgraded back to jellybean from kitkat in order to root kitkat and it worked perfectly. There's nothing about the root process for jellybean that will hurt the phone or cause data loss.
