Two weeks ago, Sprint had sms issues. Next day they cleared up for my wife, but not for me. Specifically, while she could send and receive sms on her LS990, I could only receive sms on my LS990. Called Sprint and they had me enter the ##72786# into the dialer and power cycle the phone (I think it was the 72786 code). At that point, my phone would not connect to the Sprint LTE network to make calls or access the internet. All apps dependent on an internet connection displayed errors.
Prior to this, I had problems updating the profile and PRL...meaning, I would select each option and nothing would happen. The phone would not display a new screen, no message popped. I concluded that no update happened because the PRL version remained the same.
I rooted long ago using stumpd. I also recall doing something to block the OTA OS update, though don't recall what that was now.
Okay, so the questions:
1) If I do a factory data reset, do you think my sms, internet, and phone connectivity problems will be fixed?
2) If I do a factory data reset, will I brick the phone if I do the reset before unrooting the phone?
3) I've seen a couple of threads about using the lg flashtool to unroot and return to stock and they're intimidating. Do you have any advice or a suggestion on the best resource to unroot the G#?
Thanks in advance. I hope I provided enough information for some help here.
Actually lg flash tool is not as difficult as it seems. It's the safest and simplest way to return to stock with no root. I can't speak for many roms but if you are on a stock based rom you can do a factory reset without bricking your phone, i would assume it's safe for all roms. Factory reset basically just removes and resets everything except things stored on your internal and external sd. This is likely your simplest option. Worst case you soft brick and have to use flash tool. Hard bricking is very very uncommon and even that is fixable with a paperclip. Good luck!

Thanks, Decep.
No custom ROM installed. I rooted with Stumpd, then installed the Framework to use things like G3TweaksBox.
I am wondering, though, if the factory data reset will unroot the phone? I thought I read that it did not. Hence, I think, in my problem here, that the root is what's causing the phone's connectivity issues.
I'll try the factory data reset first...and report back.
wife has had problems receiving calls. phone never rings its going straight to voice mail. hers is bone stock zva. mine is rooted and on zva and i have no problems. gonna factory reset hers and see if that helps
So uninstalled xposed and then used full unroot in SuperSU. Via root checker, I am no longer rooted.
Did factory data reset; activated phone on Sprint's network; but cannot send/receive calls/sms, etc.
Attempted to go the flashtool route, however, I cannot install the lg drivers...well, my pc says that install was successful, but when I open up device manager, I don't the lg under Ports. Can't figure out the problem. Tried running the lg installer as admin and still didn't work.

Hi all, I originally rooted my phone using this post several months ag http://forum.xda-developers.com/showthread.php?t=2380325
I'm still fairly new to the dealings of root, and have found that I only used it to have access to a couple of cool apps that required root and at that rate I don't even use any more. That being said, I finally accepted the most recent update being okay that I would likely loose my root access. The update kept failing, I assumed because of the root. I backed up my personal data, and performed a factory reset from the phone. The phone still has superuser from the reset and still fails to update. Could someone help me return my phone to fully stock configuration? Thanks!

Find out what odin is. Then..
Google "odin emergency tar (your build number here)" or something to that effect.
If you don't know your build number then you have some more research to do. Good luck.
I'd recommend using the Verizon update assistant. Much easier, but takes about half an hour to do:
1) Connect phone to PC using USB cord
2) When prompted for what action to take when this device is connected, select Verizon update assistant. Installation will take a few minutes.
3) Start the update assistant and confirm that you want to update the phone. The update will take a few minutes.
When the update is complete, you should have the most current update (MK2), and no root access. Should you need root again, try Saferoot - it's quick and easy:

Thanks for pointing me in the right direction guys, I'll do some more research into both and report back soon.

You need to flash the same stock image as what was previously on your phone.
If you don't know what version you were on previously, flash MJ7 or MK2.
I connect my Galaxy Mega (i9205) to kies and it showed that my phone have new update. Bear in mind that my phone is rooted previously (CWM). Kies updated my phone to I9205XXUCNA3. I update my phone with no problem (it took longer time only) but unfortunately KNOX ruined everything. It keeps on saying that SuperUser is trying to access the system. Furthermore, my Wifi is not working at all. I tried to click on the toggle button but no to avail.
So after searching, I found out how to disable KNOX - By flashing using vcoreroot-v2. Done flashing with this file, and now I can't see my interna; SDCard. I'm doomed and now I don't know what to do to turn back to how it was before.
Anybody that can help me, really appreciate it.

I see that so far you have found a way to disable knox AND cripple your Mega...
IMHO the best way to fix this situation is:
1. Download once more your newest firmware I9205XXUCNA3 (e.g. from Sammobile) and flash it by Odin to resolve starting position. Or try to restore your firmware through Kies.
2. Then BEFORE YOU DO SOMETHING read forums to find information how safely root firmware with KNOX. You have to be known so probably your warranty is already void and if not so it will be on the first attempt to root your unit. You are warned... There are some threads about rooting KNOX-ed firmware and even how to come back (partially) to previous build.
BEWARE! Do not attempt to flash older firmware lest you brick your Mega. New bootloader prevent from downgrading and if you try you will have endless bootloop. Upgradindg to newest firmware is one way trip.
OK I've followed your advise:
1. Re-download I9205XXUCNA3 from Sammobile and flash using odin.
2. Re-apply vcoreroot-v2
and after reboot.... WALLA!! My phone is back to normal again! And same goes to my internal SDCard, back as normal.
I have a problem with messaging where it keeps on crashing at first. But then I boot into recovery, clear cache and apply factory reset.
Now, all back to normal.
Anyhow, thank you so much for the tips. Now I can ease out a bit

Soory stapler85. I'm posting bull****.
Again: I don't have safestrap, therefore, I've only the stock rom. However, at I'm going to do a factory reset in the near furutre, and was just curious, whether the device must be rooted afterthat or the factory reset would not affect the system apps/data.
Its funny when people post a question, get an answer, and then claim they dont like that answer.
Perhaps if you gave correct information you would get the answer related to what is going on. You said you were on a ROM slot, so factory reset of that slot will NOT make you lose root just like stappler85 said. Now you just said you are not on a slot but on regular stock, so yes a factory reset probably will make you lose root of your stock system.
If you think about it. You are going to root the stock rom anyway. Why not factory reset FIRST so you know it wont mess up. Then root and SS etc.
But im sure factory reset on rooted stock rom will mess some things up. This device seems unpredictable and probably amazon intention to deter messing around with.

If you read his post he explained that safe strap does not exist for his version of kindle. Therefore he did not receive an answer for his question and your entire post is in error, as well as utterly useless. As for this particular device I can't say but on MOST android devices I've owned root stays even after a factory reset. Must re flash or Un root on many of my other devices I've had to reset, just re downloaded supersu.

You should not lose root by doing a factory reset on a working system. You may however lose superuser app if you do not have it installed into system . Open superuser be sure binaries are updated scroll down in settings and be sure superuser is installed into system and you will be fine . To do a factory reset per security settings . Keep in mind if you want to do a reset it will wipe Sdcard and everything you have copied to tablet so backed them up onto your PC and put them back if you wish to keep it

Thanks to all who are commenting on this post. I started a similar thread earlier because I didn't realize this one was asking a question similar to what I would like to better understand.
I rooted an HDX 7 running 13.3.2.2 using Towel root. All works well. I may sell this tablet in the very near future in order to upgrade to an 8.9 HDX. Is there a simple process for fully UN-rooting this tablet and resetting it back to stock as if it just came out of the box? I am not concerned with losing any personal data on the tablet.
I stress simple because my skills are limited and I do not want to risk bricking. If the risk is too high, I would rather sell it as rooted and erase all user data.

Love it! Thank you!
Alright, I don't really know what happened or what I did, but something bad happened. To begin with, I rooted my phone with Stump and that went fine. After a month or so my phone started to lock itself out and sometimes not unlock. This bug, I don't know what it was, was probably from one of the roms. I uninstalled and removed all the roms and "unrooted" my phone. When I try to root my phone again, it sees the phone as unsupported. I did a hard reset/ I even used towelroot and that was bad. My phone also can't be used on my computer because it won't read it as an LG device with a driver. I've hard reset several times and tried many things. What I know for sure is that one rom or something didn't get removed. For example, I had an emoji switcher rom and I still have Google's emoji's instead of the default LG after reset. I can also lock my phone by double tapping the top left corner, which was another rom. This is all when "unrooted"
Can someone help me fix this? I don't have a warranty on the phone and SuperSU doesn't let me do anything on it.

after removing root, you need to flash back to stock to get it working again with the exploit.

You have to flash back to stock via the link below. Once you Unroot it is the only way of getting root back. Plus it is always nice to know how to return to stock before someone starts rooting, flashing roms etc... so when you get into this positions you already know the solution.
Edit: Make sure you do not take the System update after you flash back to 10b otherwise you will not be able to root any way.

Did you get back to stock via the method I supplied? It has to be done that way and then check in your "about phone" and verify you are on "10b". From here the phone should take the 11c update.

Did you disable anything ?
If you returned to stock v10b via the .kdz file, you will not get the OTA because your are on an earlier version of v10b than the phone released with.
You are in a perfect situation to flash bumped TWRP recovery and then the v11c modem, system, and boot images, effectively updating you just like the OTA would have.
If you require the OTA to self-apply, then you need to restore using the .TOT method.

How can I flash a newer version such as 11c(Or upcoming Android L)? Without .tot
You can't. You kdz back to keep from getting the update so you can root and bump and flash roms. You tot to get to the right version to take the update
Once L is released OTA, our noble developers will make it possible for us who have root and recovery to flash the OTA components safely, retaining root and custom recovery.
We hope.
Why would you want to take the current locked OTA?
If you TOT you can still root. Before you take the update.
I am giving two VZW GS4's to my parents for Christmas and I would like to make things as simple as possible for them, which means getting rid of all the boatware that Verizon/Samsung includes. I'm familiar with rooting/flashing etc. with my Sprint GS4, but I am still somewhat bewildered by all the info regarding the VZW phones and all the different versions.
These VZW phones are on the NC5 baseband (?) and if I understand correctly they can be rooted with towelroot but cannot install a custom recovery because the bootloader is locked.
Once I root, will the phone still receive OTA updates and install properly, or will there just be a continual message saying that the update failed?
I don't plan on trying to install a custom ROM, but if I understand correctly the only way to do so is by using safestrap?
Is it possible to backup the phone, similar to a ROM backup in TWRP for example? Will I be able to return to a full stock state after root? In other words, after I root what happens if I do a factory data reset?
Thanks in advance.

1. You are correct. The nc5 can only be rooted. The bootloader is not unlocked or even possible to workaround; safestrap is your only option.
2. Once you root, your phone will not be stock anymore so OTAs will not work. You must unroot and restore your phone back to stock in order to update via OTA. However, if you learn how to use ODIN, your life will become much easier.
3. Safestrap is the only way.
4. You can backup with Safestrap. Yes you will be able to return back to a full stock state using ODIN. If you use ODIN to factory reset, your phone becomes back to stock i.e. unrooted.

Thanks. One more question: Once rooted, if I stay on the stock rom, will the phone still receive OTA update notifications (even though it will fail install)?
I'm a little familiar with odin so I should be able to go back to full stock if necessary.

Yes, unfortunately, you will receive constant update messages. However, if you are rooted, you can stop these messages. Download an app called "titanium Backup" and freeze fwupdate.apk. That specific app is what causes all the update messages to appear.
