If you are reflashing stock KDZ, you don't need to worry about unrooting, as it will wipe off everything you currently have on your phone, anyway. For information about flashing KDZs (and a whole lot more), here is a good place to start. Original stock ROMs for OG are available here -- pick the one you need.

Help on rooting back to stock rom

Hey guys, I am rooted and running Virtuous rom and I just wanted to know IF I ever wanted to go back to the stock G2 rom what would I have to do that? Thanks
Sent from my HTC Vision using XDA App
two options:
1. If you were smart, you made a nandroid of your stock ROM the minute you confirmed the root procedure worked. If you did, simply use ROM Manager or boot into recovery, wipe everything, and restore that nandroid.
If you didn't....
2. Download one of the many stock ROMs in the development subforum, and flash that through ROM manager or recovery. Remember to wipe anytime you switch between ROMs (especially Sense-to-stock, or vice versa).
Is there any stock roms on rom manager that I can just do from there?

Nope, just Cyanogen and Virtuous. Just find a stock ROM that you want to use, download the .zip file, and put that on your memory card (don't unzip it, just drop the whole .zip file as-is). Then, in ROM Manager, choose 'Install Zip from SDcard' and navigate to wherever you put that zip file. ROM Manager will give you the option to wipe and to perform a backup of your current ROM before it flashes the new one - choose both options and let it run. super easy.
Alright thanks man

That's not a stock ROM at all though, it's a custom ROM.

So it's not a stock ROM then ? If someone is looking for a stock ROM, then flashing a custom ROM isn't going to be what they need, surely ? Because they may well not want root either. Often folks ask for a stock ROM because they are doing a warranty return or similar. Or just want to go back completely to how it came from the factory.
That ROM that you linked has also got a modified RAM disk, and is zip-aligned. So it has several changes from a stock ROM.
If you're doing warranty work, that's close enough to stock. I don't thing you can 'unroot' your phone and go back to *totally* stock.

It's very straightforward to remove root, there are several guides on it in the dev section.

That's funny I never saw where he asked for a complete stock, unrooted rom for warranty purposes, guess you should give him the right link then since you seem to know what he REALLY wants. and from his second post by asking if he could find a stock rom on rom manager I would think since rom manager requires root to work, he might be looking for a stock rooted rom.
If you want to correct people please give the right awnser then, in this case give him what he's really looking for, as far as the link I provided it seems the only person not happy with the awnser is someone who didn't even ask the question, so keep up the good job "awnser police".
Just curious how much time did you spend researching that I am wrong instead of giving the OP what YOU THINK is the right link??? Time well spent.
But I guess it seems to happen, instead of awnsers we get posts trying to prove who's MORE right.
Well no hard feelings on my end, hope you have a great day, and happy posting.

[Q] E975 running e973 stock kdz

I rooted my international version E975 last night but because I'm a bit noob I didn't realise I also had to unlock the bootloader. So when I installed CWR I got stuck in the secure boot loop. I managed to get out of that with the KDZ loader through 'download mode' however I wasn't able to find the correct stock rom. Each time I tried to download the australia E975 rom it would fail download half way though, getting only 500mb or so.
I tried heaps of other links to the rom but they all seem to be broken. In the mean time I found another rom and loaded it without realising it was for the E973. So it's out of the boot loop, but it thinks it's an E973 now and I don't have any 3g/data access and the rear camera doesn't work.
So my question is: where can I find the stock rom for the australian version of E975? and ultimately I want to root, unlock bootloader and install the custom 4.3 rom. Do I first need to be back to 4.1.2 to do that? or can I do it from the wrong E973 rom, running 4.0.4?

Why not try the rooting procedure again on the existing Rom, unlock boot loader, install CWM and flash any custom Rom you want ?
Sent from my LG-E975 using Tapatalk 4
That would definitely solve the problem of not being able to find the stock rom, but I was concerned that most of the guides I've read state that the starting state should be 4.1.2.
I'm worried that starting with the E973 rom might cause some incompatibility during the root/unlock/freegee/rom install...

I'm not an expert, but I believe you can flash any Rom as long as you do a clean wipe, and the hardware supports it.
Edit:
Well, maybe you better wait till a real expert confirms this.

Guide to Update to KitKat on a Rooted Phone

Hi All,
With all the threads about bricked phones, I wanted to take the safer route and outright ask for the best method to upgrade to KitKat on a rooted phone running 4.2.2 stock? I've already 'bricked" my phone once last year doing an OTA update, so I'm trying to avoid doing that again. I know this is a noob question, but I haven't been able to locate a sprint specific guide consolidating all of the information out there. Any help is appreciated.

Thank you for the reply. I'll give this a shot tonight!
I have a question: I already screwed up and applied the KitKat update to my rooted G2 without thinking. It's now stuck booting to TWRP, where I was a moron and of course didn't create a backup at any point. Is there a way for me to sideload the ROM onto my phone at this point?
Any ideas?

Even sideload may not help you, if you can access down load mode. You might get to use tot, back to stock.
But there is no stock zvc yet for ls980.

I actually read a bit more and decided to hold off on the update. I'm happy with my phone's performance, so I really don't have the time to troubleshoot should the update go awry.

I'm the same way, but I figured that I should just go ahead.
So I'll throw that out, anyone pick one of these methods have a preference? I'm on TWRP, rooted, stock ZVA. Some mods including tether and camera. Thanks.

OTA update bricked my phone. Need advice

Hi all,
mt LG Optimous Pro G E988 has been working fine for 6 months,
But over night there was a OTA update, and now my phone is "stuck"
I say stuck because it will boot with the message
"Secure Booting Error"
"Cause: Device Unlock!! So Boot Sucess!!!"
then it goes into my CWM Recovery....
I had rooted with cwm
Here is where I am having the problem. It never fully installed the OTA update, because I had a boot loader installed.
I had tried to wipe everything and do a factory update, but no use.
I also tried using LG Mobile Support Tool to reflash the factory ROM
as per: http://forum.xda-developers.com/showpost.php?p=45953380&postcount=1
Yesterday when I tried it, the LG f;lash tool said it was not able to connect to the LG Server
But today the program is saying there is not enough power and may cause a problem.
I have just charged the phone for 9 hrs straight. I don't believe that it's undercharged
Is there a way for me to flash the phone with the original ROM without connecting to LG's server (using their Support Tool)?
Please help.
Thanks
Since you already have CWM installed I hope you have a backup which you can restore. Backup your apps and settings using tools like super backup or titanium. Then reload the JB 4.1.2 kdz from pc. You can look for the steps on xda forums. Once that is done successfully you will loose root. Then try official update via OTA. Or you can try to update via pc tool. Someone already shared the kitkat kdz on xda forums. You can try that too. All the best.

Unfortunately I do not have the backup anymore.
I also tried updating via the LG Mobile Support Tool, which did not work as it gives an error about not being able to connect to the server
I tried the guide from Madmack "[GUIDE] [E980] Fix soft bricks. Flash back to stock using LGFLashTools"
But I have not been able to locate the TOT file for the international E988
I tried to use the one he provided and it did not work (yea I'm desperate to try anything now)
Anyone out there have a TOT file for the international E988?
Or is there a way to crate one from the KDZ files?
please help
thanks
Not sure why you need a tot file. Kdz is fine. Look in xda for guides on loading the kdz file. That is a sure way of unbricking your phone. If it is still bricking after kdz load go jnto stock recovery and clear all caches and reboot. Most guides i have used mention this as an optional step.

[Q] from CM11 to stock rooted

Soooo I'm on CM11 M8 right now and I want to go back to a stock LG ROM (never thought I'd be saying that). I had to downgrade to zv8 to get cm to work, is there anything special I have to do going back? This is my 5th android device and like the 10th that I've rooted/tinkered with, and I've never seen such convoluted methods involved with flashing/OTAs etc. And I thought rooting my T-Mobile G2 (HTC desire z/vision/whatever) was a process. So yeah I just thought I'd ask before I flash this stock rooted zip. I've had to TOT this phone twice already and I don't feel like going through all that again.
